The Good Food Institute launches global $3-M competitive research grant program The Good Food Institute launches a $3-million competitive research grant program to encourage universities and others to pursue plant-based and clean meat research. This money will be awarded to projects led by scientists from around the world and from any sector to advance knowledge within the fields of plant-based and clean meat. Plant-based and clean meat has become quite the attraction in Silicon Valley, enticing investments from the biggest names in tech and venture capital, from Bill Gates and Sergey Brin to DFJ, Kleiner Perkins, and Google Ventures. Even global meat giants Tyson, Cargill, and Maple Leaf have backed plantbased and clean meat startups. Despite its potential to revolutionize

the food system and allow researchers to solve some of the world’s biggest problems – from climate change to antibiotic resistance – the Good Food Institute (GFI) estimates that less than 0.3 percent of the world’s universities are currently engaged in plant-based meat (PBM) or clean meat (CM) research. To jump-start this research, the Good Food Institute (GFI) has identified the universities with the greatest potential to advance the important fields of plant-based and clean meat. These 24 global universities have been identified for their relevant technical expertise, research capabilities, and private-sector partnerships. They are (in alphabetical order):

“While most of these schools are not yet working in these fields, their potential to become leaders in plant-based and clean meat research is impressive,” notes GFI Scientific Foundations liaison Dr. Erin Rees Clayton. “We would be thrilled to work with them to realize their potential to do cutting-edge science that will ultimately improve global health, food security, and environmental stewardship.” There have already been examples of universities having a major impact in the space. USDA-funded research at the University of Missouri was key for the plant-based meat company Beyond Meat. Dr. Mark Post’s research at Maastricht University led to the first

NSERC awards Plantform and Guelph scientist with Engage Grant

The Natural Sciences and Engineering Research Council of Canada (NSERC) grants PlantForm Corporation and a University of Guelph scientist a $25,000 Engage Grant. The funding will advance research by Dr. Lewis Lukens who is focused

on understanding and limiting defense mechanisms in host plants with the goal of increasing the yield of target proteins produced in PlantForm’s vivoXPRESS manufacturing process. The high-yield, low-cost vivoXPRESS system uses tobacco plants infiltrated

with Agrobacterium to express target proteins for development of biologic medicines and vaccines to treat cancer, inflammatory diseases and other life-threatening or debilitating conditions. Although the process uses nonvirulent strains, infiltration with Agrobacterium triggers defense responses in the plants that can limit the yield of the desired proteins. The $25,000 Engage Grant will support research aimed at providing a comprehensive analysis of small RNA molecules (sRNA) generated in response to Agrobacterium infiltration and how they impact protein expression. “Small RNAs (sRNAs) are known to play a role in plant defense and gene silencing,” says Lukens, an associate professor in Guelph’s Department of Plant Agriculture and a leading expert in bioinformatics and quantitative genetics. “The goal of this research is to identify and quantify sRNAs generated in response to Agrobacterium infiltration and transient transgene expres-

clean meat burger in 2013, followed by the formation of the clean meat company Mosa Meats. “There are so many interesting scientific questions to answer,” says Dr. David Welch, GFI’s director of Science and Technology. “What are the best cell types and cell culture methods for clean meat production? Which crops produce the best plant-based meats and are best suited for growth in each region of the world? It’s a curious mind’s dream.” Uma Valeti, MD, co-founder of clean meat company Memphis Meats, made the move from medicine to meat to maximize his impact. “If I continued as a cardiologist, I might save maybe a few thousand lives over the next thirty years. But if I am successful in helping to change the way meat is made, I could positively impact billions of human lives and trillions of animal lives.” To see this story online visit https://laboratoryfocus.ca/the-goodfood-institute-launches-global-3-mcompetitive-research-grant-program/

sion, and to investigate if production of specific sRNA correlate with transgene expression and protein production.” The project will help PlantForm continue to advance and improve the vivoXPRESS platform. On a commercial scale, a 10 per cent increase in the production of therapeutic proteins can result in millions of dollars in additional cost savings or revenue for the company. “We’re very pleased to be working with Dr. Lukens and his team to develop methods to suppress transgene silencing and increase yields of recombinant proteins,” says Dr. Don Stewart, PlantForm’s president and CEO. “This project will generate novel insights into the role of sRNA in protein expression and further advance PlantForm’s strategy to make life-saving medications available at much lower cost.” To see this story online visit https://laboratoryfocus.ca/nsercawards-plantform-and-guelphscientist-with-engage-grant/

Five data management challenges

in genomics research labs

Back in 2010 the then-CEO of Google, Eric Schmidt, was quoted as saying

Moving the data

that every two days we create as much information as we did from the dawn of civilization up until 2003, which he figured was approximately five exabytes of data. To put that into perspective, one exabyte (EB) of data is equivalent to one million

The first challenge customers experience is moving the genomics data. Not only is the size of the datasets an issue, so too is moving data from different storage layers by manual scripts — which often involves a team of IT administrators. First, the data needs to be moved out of the genomics sequencer into a high performance computing setup. From there, it needs to go into production storage and later into secondary storage for longer-term retention. Creating the manual scripts required to move the data from one stage to the next is time-consuming and expensive. However, if this process were automated, the lab could not only save time but also reduce the number of employees it takes to do the job from a team to one IT admin. Automating the process also improves the accuracy of the data and avoids drop downs of manual scripts, which are less reliable because human error is inevitable. While there are no specific percentages of how much time is saved with automation versus manu-

terabytes (TB). Take that and compare it to how much data a genomics research lab creates. For example, a small- to mid-sized research lab would have between three and five DNA sequencers — an instrument that converts a physical DNA sample into data. Each sequencer would generate 500-600 TB of data per year, which is equivalent to 0.0005-0.0006 EB or 0.0015 or 0.0018 EB for three sequencers and up to 0.0025 or 0.0030 EB for five sequencers. Worldwide there are now more than 2,000 next-generation sequencers and that number will continue to increase. Because of the volume of data involved, many of the challenges surrounding genomics and data management derive from the technologies needed to store and analyze the raw

sequencing data. On top of that, the availability of deep and large genomic datasets raises concerns over who has access to what data, data security, as well as subject/patient privacy. These challenges can be broken down into five key areas that need to be addressed in order for the field to continue its rapid advances in medical and scientific research. The following challenges are based on speaking to real-life customers where use-verification models were applied to mirror the data management process a genomics research lab would typically adopt. All of the customers identified these challenges and said a solution to automate the process would help in terms of time and cost savings.

al scripts due to the fact that each lab is different and the amount of data they handle varies, it is a very high percentage and the benefits far exceed moving the data manually. Automation can be achieved with software that offers storage lifecycle management, making it easy to move the data in and out of secondary storage for when it might be needed in production to analyze or search the data, for example.

Understanding the data Once the data is where it needs to be, the second challenge is indexing the data in a repository so that it can be searched and analyzed. This process also requires manual scripts and can be improved with automation. Storage lifecycle management software offers indexing capabilities to make the data searchable in a virtual repository, which means that the lab doesn’t have to invest the time and money associated with moving it from a physical location. Instead, a virtual repository can be created and connected to indexing and reporting structures as well as analytics Application Programming Interfaces.

Sharing and securing the data The next two challenges are particularly important given the sensitivity and private nature of the data. How the data is shared and with whom it’s shared, without losing any of the data or failing to meet compliance regulations, is a significant challenge. An endpoint and edge solution can be added to allow data sharing with very high security and data protection levels, along with auditing/reporting to let the IT administrators know what they’re sharing, who they’re sharing it with and what levels of access each person has to that data. As explained above, the virtual data repository can be connected to reporting structures, which gives IT administrators policy driven information about who has access to what data and what types of levels of access they have. This adds a high level of security and protection around the data if it can’t be backed up for some reason. Because of the extremely large size of the dataset, protecting that data without automation involves a significant investment in time, money and resources. However, by automating this process and linking it to the lab’s policies, data security can be streamlined, saving time and resources while preventing the data from getting into the wrong hands.

The first challenge customers experience is moving the genomics data. Not only is the size of the datasets an issue, so too is moving data from different storage layers by manual scripts — which often involves a team of IT administrators. Pipelining the data The final challenge is data pipelining, in which the data is run through different levels of analysis from step to step. As outlined above, the first step is moving from the genomics sequencer to the high performance compute environment and then onto the production and secondary layers of storage, depending on what the lab is doing with the data at that particular point in time. With the data processed, the lab can get real-time notifications when certain steps in the pipeline process have been performed on that data. Once level one (as outlined in the first challenge) is complete, then the IT admin knows it’s time to proceed to the next step. With one data management platform rolled out across the lab, IT administrators and researchers can address all the data management challenges. Depending what they already have in place, they can take all of the solution, including hardware and software, or parts of it as they need. Overall, the platform saves them time managing, developing and administering manual scripts. On top of that, they gain an added protection layer that will save them money on traditional backup. The latter benefit is particularly pertinent for these labs as often these types of research institutions fully depend on public and private research funding and budgets, so they are looking to achieve their goals from a business and scientific standpoint with the least amount of cost. The time saved also helps contribute to the bottom line as labs that have automated these processes for data can be more productive because they can depend on one admin looking after the entire process from a single screen.

Where is the PACS for genomics? While these challenges can be addressed by a data management platform, there is still no equivalent for the genomics world like the picture archiving and communication system (PACS) system for the imaging world. Data management does bring

some sanity to the madness of the enormous genomics research datasets and the complexity that comes with them. Beyond these challenges, however, there’s still the question of cloud computing and what role it has to play in genomics research. To date, most of the data in genomics research has been stored on premise due to the size and sensitivity of the data. But that doesn’t rule out the cloud completely. One of the main challenges is the size of the data sets — because you’re dealing with hundreds of terabytes or Petabytes of data, there’s an inherent bandwidth issue with upload and download times when it comes to moving data in and out of the cloud. This is also quite a complex and costly exercise compared to moving data around on-premise. On top of that, storage isn’t cheap. However, if storage consumption can be brought under control by a data management platform, then the workloads can be automated and managed from a single dashboard. This makes it easier to move the data into production when needed for analysis and then back into secondary storage when it isn’t needed. In turn, this helps to optimize cost performance. When it comes to sharing the data with other labs, one of the biggest challenges aside from those already mentioned is that unlike imaging data, which is used for diagnostic purposes, genomics data is used for research and varies from one institution to another. The process under which the data is collected, stored and analyzed is also more ad hoc compared to a unified system like a PACS in the imaging world. One of the key reasons for this is the genetic sequencers are siloed. Until this changes, there will always be components of the data gathering, management, storage and analysis that require an outside platform to connect them. The way in which the data can be interpreted also varies greatly compared with imaging data. Genomics data can be used in a multitude of ways by different research institutes and organizations, meaning that a one-size-fits-all platform

won’t work in all cases and it needs to be configured on a case-by-case basis.

The future of genomics Although automation is tackling many of these challenges head on, there’s still a long way to go before genomics research labs can really reap the rewards that data management platforms promise. Many vendors are still looking at how they can take data management out to the market and apply it in a real world scenario. The study of genomics in Canada is growing and this country is one of the leaders in the field. All of the main universities in Canada have research labs that are involved with genomics research. Canada is also recognized worldwide for Genome Canada, a not-for-profit organization funded by the Government of Canada and working to harness the power of genomics for the benefit of Canadians, including the fields of health, agriculture, forestry, fisheries and aquaculture, the environment, energy and mining. As technology improves, so does our ability to gain better insights from the study of genomics and enhance the lives of people across Canada and around the world. But it’s important to remember that genomics data is only as strong as our capacity to manage it. Labs must find solutions that solve the five data management challenges in order to keep up with the rapid advances researchers are making in genomic science.

How to Evaluate Your Next Ultra-Low Temperature Freezer Purchase: Caveat Emptor

The development of ultra-low temperature freezers spans decades of progress in component design, electronic supervision and cabinet construction.

rom refrigerants and compressors to controllers, cabinet insulation and data logging, manufacturers have established a myriad of internal operating metrics shaped to position their ultra-low temperature freezers as the best on the market. In recent years, however, the industry-wide creation of ENERGY STAR® criteria for universal assessment of freezer performance has begun to bring credible, third-party insight into a reality that was previously left to manufacturers alone. Today, facility and biorepository managers, along with end users, are

becoming more knowledgeable about key performance factors that ultimately define the suitability of an ultra-low temperature freezer for their application. As a result, the demand for independent testing and comparative evaluation of leading ultra-low temperature freezers on the market has grown, while purchasers have broadened their view of freezer specifications to evaluate the concept of performance at a higher level. This embraces three primary deliverables essential to stored product safety: reliability, recovery and energy efficiency. The first of these is reliability.

Reliability Because an ultra-low temperature freezer is acquired to safeguard years or even decades of clinical research at temperature setpoints of -80°C, or -70°C, failure is never an option. The value of frozen contents is difficult or even impossible to determine. Specimens are often irreplaceable. Therefore, uptime is the most important function of an ultra-low temperature freezer. It is also the single most challenging attribute that leads to uncertainty and impact on reproducibility in scientific research. This chronic uncertainty weighs on the entire industry. The global repository of generations of research depends on the performance of a cold storage product group that, if not properly engineered, places inordinate stress on the machines as well as the people who place their life’s work inside. In the life science market, there is no central agency to corroborate manufacturers’ claims of reliability, uptime and other performance attributes critical to safe storage of biological materials. Purchasers must depend on the integrity and social responsibil-

ity of the manufacturer, truthfulness of published specifications, referrals from colleagues and testing performed by their own institutions or by independent agencies. Consultation with facility maintenance personnel responsible for outof-warranty service, or those who are factory trained and authorized to perform in-warranty service, can be highly credible sources of information. Independent service repair companies with reputable service technicians are unlikely to recommend poor performing freezers in order to earn money fixing them; the stakes are too high. Whether in-house or independent companies, these insights can offer valuable context in advance of a purchase decision.

Recovery The exponential worldwide growth in the volume of stored frozen biologicals has brought forth a demand for better energy management. New cooling systems have established impressive statistics for reducing power requirements. These include cascade platforms with variable speed compressors as well as alternative

engines. All must maintain ultra-low temperatures for indefinite storage while restoring setpoint temperature quickly and efficiently following door openings. Unfortunately, the need to reduce energy consumption has pushed some systems to the edges of prudent performance. Temperature recovery requires a combination of system anticipation and rapid platform response within the parameters of a safe mechanical performance envelope. Thus, the freezer must be designed for the worst-case reality of daily operation where room temperatures can be high, line voltages may fluctuate due to aggregate power demands leading to brown-out conditions, and access to stored product may be more frequent than normal. The accumulation of frost on door gaskets and dust on condenser coils is another reality that engineers must confront. While recovery and uniformity are related, recovery speed, which is a prime indicator of reserve refrigeration capacity and high ambient temperature tolerance, remains at the forefront of performance attributes. Interior temperature recovery and uniformity are essential to the relationship between storage location and the viability of stored product over the long term. A thorough evaluation of ultra-low temperature freezer purchase alternatives demands an understanding of recovery rates, measuring criteria such as ambient temperature at time of test, control probe location, duration of outer and inner door openings, and freezer load. Manufacturers who publish best-case recovery rates measured under ideal conditions may not account for actual use scenarios in their literature. Independent documentation of recovery performance should be a prerequisite when comparing competitive freezers, and an essential consideration when purchasing any ultra-low temperature freezer whether for replacement or new laboratory design.

Energy Efficiency Development of more energy efficient ultra-low temperature freezers has continued to reveal significant improvements in the interplay between electronic sensors embedded within the cooling circuit, firmware with algorithms programmed to anticipate cooling demand, and cooling engines or compressors designed to remove heat from the cabinet to the outside environment. As a result, the power consumption gap between leading ultra-low temperature freezers from various manufacturers has narrowed. Today, purchasers must emphasize reliability over initial acquisition cost.

An energy-efficient freezer that cannot respond to high ambient temperatures or cannot recover quickly following door openings neglects a key requirement for stable, long-term storage at ultra-low temperatures.

Purchasers must demand temperature recovery and uniformity more than insignificantly different energy costs. And purchasers must demand a rebalanced performance equation where reliability, recovery and operating costs are properly apportioned to protect a priceless inventory. An energy-efficient freezer that cannot respond to high ambient temperatures or cannot recover quickly following door openings neglects a key requirement for stable, long-term storage at ultra-low temperatures. The industry-wide adoption of ENERGY STAR criteria for measuring and documenting power consumption has offered a new set of standards by which freezers can be evaluated. Energy consumption alone, however, should not be a primary performance attribute if achieved at the expense of recovery and uniformity. As energy efficiencies continue to equalize, customers should expect energy savings over the life of the freezer that supersede the cost of operating installed freezers running on older conventional platforms. Most importantly, investments in energy efficient freezers should be made only within the context of why freezers are required in the first place: reliable, uni-

form and responsive ultra-low temperature storage of critical research. Toward this end, purchasers should demand comparative data generated through independent evaluation of all products under consideration. Through this effort, test conditions and criteria should remain constant across the board so that strengths and shortcomings can emerge in support of a purchase decision.

Laboratory compared three leading upright ultra-low temperature freezers under controlled conditions.

Electrostatic Powder Coating

for Pharmaceutical Applications

harmaceutical solid dosages such as tablets, capsules and pellets are often coated with a thin layer coating material for many purposes. Esthetically, the coating improves the appearance, market image and brand recognition of the products. The coatings also serve many practical functions such as ease of packaging, ease of swallowing and improved physical and chemical stability of the products. Applying functional coatings on solid dosage forms is an important and versatile tool to modify the drug release profiles. There are many pharmaceutical products in the market with functional coatings for taste masking, odor masking, enteric release and extended release applications. Pharmaceutical coating technologies have evolved over the years from sugar coating to solvent coating to more environmentally friendly aqueous coating. These coating processes are liquid based processes. For solvent coating, the polymeric coating materials are dissolved in the organic solvent for spraying onto the substrate. Polymeric materials are either suspended or dissolved in water for aqueous coating. Due to strict environmental regulations, aqueous coating has quickly replaced solvent coating for a majority of liquid coating processes except for some controlled released applications such as osmotic delivery and pellet formulations which still require solvent coating processes. The major limitations associated with liquid coating processes are: • Microbial contamination in aqueous coating processes • Aqueous coating is not suitable for moisture sensitive drugs • Potential moisture related product stability issues of the finished products

• Expensive air handling systems are required to remove water vapor and solvents • Strict solvent emission regulations limiting the use of solvent coating processes

Electrostatic Powder Coating for Solid Pharmaceutical Dosage Forms Solvent free and water free powder coatings are desirable alternatives to overcome the short comings of liquid based coating. A patented electrostatic powder coating technology for pharmaceuticals was invented by Professor Jesse Zhu at Western University after over two decades of research in powder coating.1-6 The technology utilizes pharmaceutically acceptable materials and a combination of electrostatic force, thermal energy, hydrodynamic force from the powder spray and mechanical energy from the rotation of a coating pan to coat pharmaceutical substrate directly with dry powder. The electrostatic powder coating technology has overcome the major technical challenges facing pharmaceutical powder coating to make the coating process amendable for commercial use. The challenges include powder flow, reduction of glass transition temperature of the polymer used and powder adhesion to the substrate and curing to form a uniform coat. The electrostatic powder coating process is shown schematically in Figure 1. The substrate is loaded into a pan coater and pre-heated to approximately 60°C. A suitable plasticizer is sprayed onto the substrate to lower the glass-transition temperature of coating polymer to soften it and facilitate powder adhesion on the substrate. Ultrafine powder is sprayed onto the substrate using an

electrostatic spray gun. The coating pan is grounded to create a potential difference leading to electrostatic attraction between the substrate and the charged powder. The coated substrate cures at a temperature slightly above the glass-transition temperature of the polymeric coating material to form a uniform film coat. Many commercially available pharmaceutical coating materials from major coating materials suppliers such as Evonik, Colorcon, Dow Chemical and Kodak for controlled release applications have been successfully applied on tablets, HPMC capsules and pellets using the electrostatic powder coating technology. Immediate release coating materials include Eudragit® EPO (taste masking), as well as Opadry® II and Opadry® AMB (moisture barrier). Enter-

ic release coating materials include Eudragit® L100 and Acryl-EZE® MP. Extended release coating materials include Eudragit® RL100 and Eudragit®RS100, ETHOCEL™ and Cellulose Acetate from Kodak (Omotic delivery devices). Other coating materials to target drug release at the lower GI track can also be used in the electrostatic powder coating. A comparison of powder coating and liquid coating for pharmaceutical applications is shown in Table 1. Key advantages of powder coating are listed below. 1. Avoid moisture related problems 2. Energy efficient and environmentally friendly 3. No need for expensive exhaust equipment and air handling system to remove water vapor or solvent. The equipment and facility

terial deposited on the substrate; and hence, the thickness of the coating, can be controlled by the electrical voltage setting of the powder spray gun. The electrostatic repulsion of the charged powder particles promotes even distribution of the powder on the surface to form a uniform smooth coating. The coating uniformity of powder coated tablets with different coating polymers has been studied using Laser Induced Breakdown Spectroscopy LIBS. The coating materials usually contain titanium dioxide and sometime magnesium stearate. Upon vaporization by a laser, the titanium and magnesium form excited ions which emit photons. The emission intensity is related to the amount of titanium and magnesium in the coating. By measuring the variability of the ion intensity from different locations or depths of the tablets, the variation of the coating thickness and uniformity can be assessed. Three ibuprofen tablet batches were coated with three different types of functional coating polymer for taste masking, enteric release and extended release.4 The LIBS data of the three powder coated batches were compared to a marketed ibu-

Example 1: Powder coating for enteric formulations Enteric coating is insoluble in low pH and allows coated tablets and capsules to pass through the stomach without releasing the drug. The coating helps to protect the acid labile drugs from hydrolysis by the stomach acid and prevent stomach irritation caused by drugs such as Aspirin. Aspirin tablets and HPMC capsules containing Aspirin (81 mg and 325 mg strengths) have been successfully coated with Eudragit® L100 - 55. The dissolution profiles of the enteric coated Aspirin tablets and capsules and the commercial Bayer Aspirin Tablets are shown in Figure 2. The powder coated tablets and capsules meets the USP dissolution requirement of less than 10% release during the acid stage testing. Example 2: Powder coating for small pellets Small pellets pass through the GI track at a steady pace which is very desirable for controlled release applications. Also, multiple coating layers for different functions can be applied on the pellets successively (Figure 3a). Piroxicam pellets with a particle size of 0.9–1.18 mm have been successfully coated in a pan coater with Eudragit® L100 – 55, Eudragit® EPO and Eudragit® RS/RL for enteric release, taste masking and extended release applications respectively. The dissolution profiles of the pellets with the three different polymers are shown in Figure 3b. It is worth noting that coating of small pellets usually requires the use of a fluid bed coater to suspend the pellets in mid air to prevent pellet cohesion. Example 3: Powder Coating for Osmotic Drug Delivery Systems Osmotic Drug Delivery Systems are the only true zero order release delivery system and the drug release is independent of food intake. Cellulose acetate has been successfully applied by powder coating onto an osmotic tablet core containing salbutamol to form a semi-permeable coat for osmotic delivery applications. The resulting osmotic delivery system and the dissolution profiles are shown in Figure 4. It is noteworthy that solvent coating is typically

Proteogenomics as an approach to improve cancer treatment

n recent years, precision medicine has opened new avenues for the targeted treatment of cancer (or other diseases), using the best available therapy. Upon identification of somatic genetic alterations (point mutations, deletions, amplifications, etc.), specific drugs can be selected that allow the targeted treatment of a tumour.1 Genomics-based precision medicine has been successfully applied to heal cancer patients by ensuring that each patient receives the optimal treatment, but response rates are still often unexpectedly low. For some cancers, up to 50 % of patients may not respond to the predicted targeted drug treatment.2 A variety of reasons contribute to these modest success rates. One reason is that the genome defines only the potential template of an organism (its genotype) and is rather static, while biological processes are highly dynamic. This dynamic is controlled not only by those biomolecules that are encoded in the genome (i.e., proteins), but also by metabolites and lipids. The proteome is defined as the complement of all proteins expressed by an organism, tissue or cell at a given time point and condition. Its composition depends not only upon which genes are active (i.e. protein translation), but also protein degradation and post-translational modifications that alter the structure of the protein and therefore its function and activity. Thus, the proteome of an organism reflects of the actual state of the organism (its phenotype) more accurately than does the genome, and the proteome depends on a multitude of factors: environment, diet, age, gender physical activity, health status, medication, etc. To understand the causes as well as the consequences of disease on a molecular level, it is essential to understand which genes are actually

feature agglomerate of multiple cell types (cancerous and healthy), not every predicted mutation is actually present or relevant. • How many copies of each protein are really present in the tumour? Depending on the protein, the copy number can vary from a few to a several million molecules per cell and copy number is often changed in tumours compared to healthy cells or tissues. Such changes can indicate increased or reduced activity of central pathways, and these changes are not readily predictable from the genome. • Are protein activities or signalling pathways altered? Dysregulated signalling (protein phosphorylation) is one of the main causes of cancer, and many drugs target tyrosine kinases.5 Protein phosphorylation levels and alterations, however, cannot be predicted from the genome.

Genomics-based precision medicine has been successfully applied to heal cancer patients by ensuring that each patient receives the optimal treatment, but response rates are still often unexpectedly low. For some cancers, up to 50 % of patients may not respond to the predicted targeted drug treatment.2 being actively translated into proteins, which are the real drivers of biology. Indeed, genomics will fail to distinguish the tadpole from the frog. Although these two are very distinct stages (phenotypes) in the life cycle of the very same organism, they share an identical genome but can be clearly differentiated by their proteomes. In a similar way, in many cases, the molecular basis of an individual cancer cannot be completely understood by using only genomic approaches. Therefore, the combination of genomic data with quantitative proteomic data on both

protein expression and post-translational protein modifications – a novel approach termed proteogenomics3 – is now thought to be a very promising approach for improving precision medicine so that it better predicts individualized treatment for cancer patients. This unique combination will enable researchers and clinicians to address several fundamental questions: • Which genes and mutations are actually active and are being translated into proteins in a tumour? Although a tumour cell contains more than 10,000 different proteins4 and tumours are an

Proteogenomic analysis of tumour biopsies holds the unique potential to allow researchers and clinicians to fully understand the molecular basis of an individual tumour by combining precise information on its genotype and its phenotype. Ideally, this will allow clinicians to select the best available treatment strategy, or to develop new treatments that not only effectively kill all of the cancer cells, but also prevent relapse. At the Segal Cancer Proteomics Centre, we have already begun to translate our proteogenomics strategy into the clinic. We have extensively analyzed colorectal cancer tumour specimens using state-of-the-art proteomics technologies based on nano-LC-MS/MS using a non-targeted “shotgun” approach which provides an unbiased identification and quantification of proteins. This has enabled the high confidence identification of more than 8,000 proteins from individual tumours. Aligning this data with the corresponding genomic data from the same tumour samples (the genotype), has allowed us to clearly verify the presence of predicted mutations within the tumour on the protein level (the phenotype). Using this approach, we have been able to verify the presence of known driver mutations, such as KRAS G12V, in the tumour samples. After the specific mutation has been verified, we were then able to develop very sensitive targeted mass spectrometry assays which allow us to determine the actual level of that mutation in individual tumours using absolute quantification methods with high sensitivity and precision. Our goal is to provide unique

molecular signatures for individual tumours. This will allow us to better define why specific patients do not respond to treatments predicted based on their genomic profiles, and thus improve the selection of appropriate treatment strategies.

Liquid Biopsy Test Roche announces the global availability of FoundationOne Liquid, a liquid biopsy test. Many cancer patients have an insufficient or inadequate tissue for genomic testing and may therefore benefit from FoundationOne Liquid. This new test joins FoundationOne CDx to deliver a complementary portfolio which provides insights to personalise a patient’s treatment plan. FoundationOne Liquid can identify circulating tumour DNA in the blood of people living with cancer and can identify 70 of the most commonly mutated genes in solid tumours, including microsatellite instability, a genomic signature which may help inform cancer immunotherapy-based treatment decisions. From a single blood sample, the liquid biopsy offers a quick and convenient option for some patients with solid tumours. FoundationOne Liquid meets a need for comprehensive genomic profiling for people who have an insufficient or inadequate tissue, including those with advanced non-small cell lung cancer, where an estimated 15 per cent of patients are not eligible for tissue biopsy and approximately 10 per cent have a biopsy size that is insufficient to evaluate. FoundationOne Liquid works well with FoundationOne CDx, a tissue-based genomic profiling test launched in the US earlier this year, to deliver a portfolio of comprehensive genomic profiling services for healthcare professionals.

A society in transition The cannabis industry has exploded this past year in prep for the now national legalization of marijuana. This has caused an influx of companies – producers and affiliated parties – to seek the smoky trail that will bring them to the forefront of the cannabis market. According to the Canadian Marijuana Index, the value of cannabis stocks has risen nearly tenfold over the past two years. As well as that, there have been multiple mergers and acquisitions as companies fight for the top spot that keep investors eyes firmly set on the Canadian market. With expectations of the cannabis market to grow larger than the hard liquor market, it should come as no surprise that there are many companies jumping on the bandwagon to plant their seed in an advantageous spot. There are now some two dozen publicly-traded marijuana companies with an estimated combined market value of $23-billion. With this only expected to rise, it will be interesting to see what happens in this lucrative market. Canadian consumers expect high-quality product, and depending on the province, will be offered online or in government-run stores. Undoubtedly the demand will change depending on location and product offered. This ground-breaking transition is complex, and every detail needs to be intricately balanced. Public safety and privacy is paramount. However, this opens many doors for entrepreneurs and fosters innovation that can be a positive contributor to the national economy as Canada takes a leadership role in making Canada the first G7 country to legalize recreational cannabis nationally.
