It is the central tenet of modern biology: The information in our DNA (right) is translated into RNA (center), which moves these coded instructions from the cellular nucleus and translates them into proteins (upper left). In turn, proteins are the machines that power virtually all aspects of biology. Burnham scientists spend their careers studying these interactions. Each year they learn more about how cells function and what can go awry to cause disease.

The Year in Translation The recently opened Conrad Prebys Center for Chemical Genomics facility at Lake Nona can conduct hundreds of thousands of assays to find chemical compounds that can alter protein function (see page 11).
Translation has a variety of definitions. It can mean translating one language into another. In scientific parlance, translation can describe how the information from our genetic code is converted into proteins. Also, translational research is the process by which basic scientific discoveries are moved from the laboratory to the clinic.
While these three definitions describe very different processes, they all apply to the work being done at Burnham. And 2009 was a very good year for translation. It is no secret that the biological sciences have a language all their own. Complicated terminology is often required to describe complicated processes. However, Burnham has succeeded in making our investigations more accessible, and the world has taken notice. In the past year, Burnham science has been described in the New York Times, Wall Street Journal,
San Diego Union-Tribune and Orlando Sentinel, as well as on National Public Radio, Fox Business News and many other outlets. These stories allow the world to see the incredible work being done at Burnham and help advance scientific understanding. In 2009, Burnham scientists published more than 300 research papers, many in high-profile journals. The vast majority of these papers illuminated some aspect of translation. According to Thompson Scientific, in the past 10 years Burnham research has received the highest number of citations,
in biology and biochemistry, of any institution publishing more than 500 papers. In other words, Burnham discoveries spark the creativity of scientists around the world. With the opening of our new facility at Lake Nona and a new Center for Nanomedicine in Santa Barbara, Burnham expands both our basic and translational research capabilities. New scientific and administrative leadership, as well as multiple collaborations, will advance the science and help transform basic discoveries into new medicines.

called Tks5, which controls the formation of these invadopodia in cancer cells. Recently the Courtneidge laboratory showed, in an article in Science Signaling, that reactive oxygens, such as superoxide and hydrogen peroxide, play a key role in forming invadopodia. Inhibiting reactive oxygen reduces invadopodia formation and limits cancer cell invasion. “Reactive oxygen has a complex cellular role,” says Dr. Courtneidge. “Normal cells use reactive oxygen to signal, grow and move. Immune cells, such as neutrophils, produce reactive oxygen to destroy bacteria. Now we find that reactive oxygen is necessary for invadopodia formation, which allows cancer cells to become metastatic.” Invadopodia, seen as orange dots in this image, are found in metastatic cancer cells.
NCI-Designated Cancer Center Battling Meta stas i s Metastasis is a word no one wants to hear. Cells that should never leave their biological home migrate to distant parts of the body. Many things have to go wrong with cellular checks and balances for this to happen, yet it happens all too frequently. To metastasize, cells must acquire a number of properties, including the abilities to move, survive in the bloodstream, cross tissue boundaries and grow in foreign organs. These last two properties require the activity of proteases, enzymatic proteins that break down other proteins. Sara A. Courtneidge, Ph.D., director of the Tumor Microenvironment Program, studies how the activity of these proteases is controlled by cell surface structures called invadopodia. These finger-like projections from the cell membrane are found in metastatic cancer cells but not in non-invasive cells. Dr. Courtneidge’s laboratory discovered a protein,

The Sec ret World of P roteins Ubiquitination is the process that marks proteins for destruction and is critical to cellular health. Recently, Dieter Wolf, M.D., and colleagues, in an article in Molecular Cell, illuminated how competition between proteins enhances diversity during ubiquitination. Using S. pombe fission yeast as a model, the Wolf laboratory uncovered an intricate relationship, in which an array of proteins (called F-box proteins) alternately attach to and are kicked off a protein called CRL1. There are 16 different types of F-box proteins, and one of them must attach for CRL1 to fulfill its role of marking a protein for destruction. If ubiquitination goes awry, aberrant proteins can accumulate and lead to diseases such as cancer. Dr. Wolf ’s research shows that these proteins attach to CRL1 but are kicked off by the competing protein CAND1. F-box proteins and CAND1 continue to trade places until they come in contact with the appropriate part of the protein being degraded. “The tension between CAND1 and F-box gives more F-box proteins the opportunity to attach to CRL1,” says Dr. Wolf. “Without CAND1, more prevalent F-box proteins would dominate the process.” Another way proteins communicate is through enzymes called caspases (a type of protease), which cleave, or nick, other proteins to alter their function. Again, understanding how this process works leads to a better understanding of how proteins collaborate and the differences between healthy and diseased cells. Using an advanced proteomic technique called N-terminomics, Guy Salvesen, Ph.D., Dr. Sara A. Courtneidge professor and director of the Apoptosis and
B u r n h a m t h e y e a r in tr a n s l a tion
Cell Death Research Program, graduate student John Timmer and others determined the cleavage sites on target proteins. Prior to this study, published in Nature Structural and Molecular Biology, scientists believed that proteases primarily cleave in unstructured loops, unstable parts of proteins that are readily accessible. The Dr. Dieter Wolf discovery that caspase-3 also cleaves α-helices contradicted that belief and offered new insights into protein signaling pathways. “This was a big surprise because there shouldn’t be anything for a protease to grab onto in a helix,” says Dr. Salvesen. “We found that the basic concept that they don’t cleave to helices is wrong. However, though we’ve found that proteases can cleave helices, we don’t believe that’s their biological function.” Because they alter the functions of other proteins, proteases like caspase-3 are critical to cell signaling. Understanding how and where they interface with target proteins enhances our ability to understand disease.

Kristiina Vuori, M. D., Ph. D., director of the Burnham Cancer Center, and colleagues found that Caspase-8, a protein long known to play a major role in promoting programmed cell death (apoptosis), helps relay signals that can cause cancer cells to proliferate, migrate and invade surrounding tissues. For the first time, Caspase-8 was shown to play a key role in relaying the growth signals from the protein EGF that cause cell division and invasion. Published in Cancer Research. Minoru Fukuda , Ph. D., and colleagues discovered that specialized complex sugar molecules (glycans) that anchor cells into place act as tumor suppressors in breast and prostate cancers. These glycans play a critical role in cell adhesion in normal cells, and their decrease or loss leads to increased cell migration by invasive cancer cells. Published in Proceedings of the National Academy of Sciences. G ary C hiang , Ph. D., and colleagues have elucidated how the stability of the REDD1 protein is regulated. The REDD1 protein is a critical inhibitor of the mTOR signaling pathway, which controls cell growth and proliferation. Published in EMBO Reports. Stefan Rie dl , Ph.

This revealed a key mechanism in the induction of programmed cell death and unraveled a novel mechanism in receptor signaling. Published in Nature. Wei J iang , Ph. D., and colleagues have demonstrated important new roles for the protein kinase complex Cdc7/Dbf4 or Cdc7/Drf1 (Ddk) in monitoring damage control during : 8E:<I :<EK<I DNA replication and reinitiating replication following DNA repair. Since Ddk is often deregulated in human cancers, this new understanding of its role in DNA damage control could help shape new cancer therapies. Published in Molecular Cell.

When President Barack Obama reversed the federal restrictions on funding for embryonic stem cell research, he raised the hopes of millions of people around the world…Now that these unnecessary, indeed harmful, regulations have been removed, American researchers can ethically and conscientiously pursue these advances, accelerated by access to federal research funds. Burnham President and CEO John C. Reed, M.D., Ph.D., in a March 27, 2009, op-ed in the San Diego Union-Tribune
The picture in the San Diego Union-Tribune showed a hand removing a sticker—a small action with deep significance. The sticker, and others like it, described federal restrictions on stem cell research. These rules dictated that federally funded equipment was off limits. When the restrictions were reversed, the stickers came off, and the promise of stem cell research could be pursued more effectively. “The federal rules forced us to operate kind of like a kosher kitchen,” says Evan Snyder, M.D., Ph.D., director, Stem Cells and Regenerative Biology. “We just couldn’t use federally funded equipment, no matter how inefficient that made the science.” When the ban was lifted, world attention focused on
How Do Stem Cell s Function ? One of the goals of the Stem Cell and Regenerative Biology program is to understand the processes that help stem cells decide whether to differentiate, or not, and what type of tissue they should differentiate into. Alexey Terskikh, Dr. Alexey Terskikh Ph.D., is invesBurnham and other leaders in tigating the earliest neural stem cell research. The Wall pathways taken by Street Journal, Fox Business News, the BBC and many other news outlets came to Torrey Pines Mesa to find out what these changes meant for current science and future treatments. For the scientists who have dedicated their careers to stem cell research, this new freedom means expanded opportunities to translate stem cells into cures.

differentiating embryonic stem cells. He notes that cells derived from the neural crest (embryonic cells that give rise to neurons, skeletal elements, smooth muscle, etc.) become peripheral cells throughout the body—but how is that specification acquired? “When they start migrating, they’re all the same. But then they become specialized; they know what they’re supposed to do,” says Dr. Terskikh. The ultimate goal is to create cells for clinical use. The Terskikh laboratory has developed a protocol to rapidly differentiate human embryonic stem cells into neural progenitor cells that may be ideal for transplantation. Their research, published in Cell Death and Differentiation, could be adapted to produce committed neural precursor cells, one of the key requirements for clinical use.

Department of Neurosurgery, received a disease team grant from the California Institute for Regenerative Medicine. The team, which includes the Ludwig Institute, UC San Diego, and UCLA, received more than $19 million to study using neural stem cells—genetically engineered to contain a tumor-killing gene—to home in on glioblastoma multiforme. This approach is based on Dr. Snyder’s discovery that stem cells seek out cancer cells, including primary and metastatic brain tumor cells. In addition, Dr. Snyder discovered that stem cells could be engineered to deliver a range of genes, including tumorkilling genes. The goal is to launch a clinical trial within four years. P rogres s on N eurod egenerative Disea ses There is a direct relationship between how a protein is folded and what that protein does. Many diseases can trace their roots to problem proteins. This is particularly true in neurodegenerative diseases, which are commonly caused by misfolded proteins. Recently, Stuart Lipton, M.D., Ph.D., director of the Del E. Webb Center for Neuroscience, Aging and Stem Cell Research and colleagues found that normal synaptic activity in nerve cells (the electrical activity in the brain that allows nerve cells to communicate) protects the brain from the misfolded proteins associated with Huntington’s disease. They also found that the drug Memantine, which is approved to treat Alzheimer’s, successfully treated Huntington’s disease in mice by preserving normal synaptic elec-
trical activity and suppressing excessive extrasynaptic electrical activity. “We show here, for the first time, that electrical activity controls protein folding, and if you have a drug that can adjust the electrical activity to the correct levels, you can protect against misfolding,” says Dr. Lipton. “This verifies that appropriate electrical activity is protective, supporting the concept of the ‘use it or lose it theory’ of Dr. Huaxi Xu brain activity at the molecular level. Published in Nature Medicine, this finding may explain why epidemiologists have found that ‘using’ your brain by performing crossword puzzles and other games can stave off cognitive decline in diseases like Alzheimer’s.” Burnham researchers also made progress in understanding Alzheimer’s disease. Huaxi Xu, Ph.D., acting director of the Neurodegenerative Disease Research program, and others identified a novel mouse gene that reduces the accumulation of two toxic proteins that are major players in Alzheimer’s: amyloid beta and tau. Amyloid beta is responsible for the plaques found in the brains of Alzheimer’s patients. Tau causes the tangles found within patients’ brain cells. The study was published in Neuron. “From the point of view of treating Alzheimer’s disease, if we can express the mouse gene in human brain cells, we may be able to control the buildup of amyloid beta and tau neurofibrillary tangles,” says Dr. Xu.

Proteins play a key role in determining stem cell fates, and phosphorylation (the biochemical process that modifies proteins by adding a phosphate molecule) is central to protein activity. Evan Snyder, M.D., Ph.D., director of Burnham’s Stem Cell and Regenerative Biology program, and Laurence Brill, Ph.D., and others have catalogued 2,546 phosphorylation sites on 1,602 phosphoproteins. Identifying these sites will help us understand the mechanisms that influence self-renewal and differentiation. Published in Cell Stem Cell. A great deal of work has been done on aging as a systemic process throughout the body, but now researchers are looking more closely at how aging affects individual organs. Rolf Bodmer, Ph.D., director, Development and Aging, has found that the protein d4eBP controls cardiac aging in Drosophila (fruit flies). The team also found that d4eBP protects heart function against aging. Published in Aging Cell. Gregg Duester, Ph.D., Xianling Zhao, Ph.D., and colleagues have clarified the role that retinoic acid plays in limb development. The study showed that retinoic acid controls the development (or budding) of forelimbs, but not hindlimbs, and that retinoic acid is not responsible for patterning (or differentiation of the parts) of limbs. This research corrects longstanding misconceptions about limb development and provides new insights into congenital limb defects. Published in Current Biology. The Lipton laboratory has demonstrated that attacks on the mitochondrial protein Drp1 by the free radical nitric oxide—which causes a chemical reaction called S-nitrosylation—mediates neurodegeneration associated with Alzheimer’s disease. Prior to this study, the mechanism by which beta-amyloid protein caused synaptic damage to neurons in Alzheimer’s disease was unknown. These findings suggest that preventing S-nitrosylation of Drp1 may reduce or even prevent neurodegeneration in Alzheimer’s patients. Published in Science.

Infectious and Inflammatory Disease Center New str ategies , New I n s igh t s Viruses may have invented planned obsolescence. Humans, and other higher organisms, have sophisticated error-correction mechanisms to carefully limit the number of mutations in our DNA. Not so with viruses. In fact, they are designed to mutate to better evade our immune systems. But occasionally, a viral protein is resistant to mutation because its function is so complex any changes would render it useless. In February, Robert Liddington, Ph.D., director, Infectious Disease Program, along with collaborators at the Dana-Farber Cancer Institute and the Centers for Disease Control, found such a vulnerability in the influenza virus. The team identified human monoclonal antibodies that neutralize numerous influenza viruses, including bird flu, previous pandemic influenza viruses and potentially H1N1. The study was published in Nature Structural and Molecular Biology. “The head portion of hemagglutinin (the protein
that binds the virus to a cell) is highly changeable, leading to forms of the virus that can evade neutralizing antibodies,” says Dr. Liddington. “However, the stem region of hemagglutinin is highly conserved because it undergoes a dramatic conformational change to allow entry of viral RNA into the host cell. It’s very difficult to get a mutation that doesn’t destroy
that function, which explains why these antibodies neutralize such a variety of influenza strains.” The ripples from this paper were felt worldwide. With international concern over the avian flu, the possibility that researchers might have found a way to target multiple influenza strains garnered considerable interest.

Hundreds of news outlets, including CNN, the New York Times and Time Magazine, reported on this breakthrough, and interest continued for several weeks. As fall approached and H1N1 (swine) flu became a growing concern, there was renewed interest in this research. In October, Burnham sponsored an experts panel to sort fact from fiction in the H1N1 discussion. The panel featured Dr. Liddington; Steve Waterman, M.D., medical epidemiologist for the Centers for Disease Control; Patricia Skoglund, R.N., administrative director of Disaster Preparedness for Scripps Health; and Nathan Fletcher, state assemblyman representing California’s 75th District.

we come up with personalized markers? The Stedman Center has already begun to find chemical markers that identify individuals who might go on to develop insulin resistance and diabetes. This technology could also be applied to heart disease and different forms of cancer— both in making a diagnosis and looking at the severity of the disease. “The bottom line is: how do we individualize treatment?” Coll a bor ations Collaborating with clinical institutions is a key element of Burnham’s strategy to rapidly move discoveries from the laboratory to the clinic. In fact, just prior to the dedication ceremony, the University of Florida announced that they too will build a facility in the Medical City. Their presence will add additional firepower to an already potent lineup of Burnham partners, including M.D. Anderson Cancer Center Orlando and the University of Central Florida. The Florida Hospital-Burnham Translational Research Institute (TRI) is a great example of how these basic research/clinical partnerships will work. The TRI combines scientists and clinicians with incredible technologies to enhance translational research and bring new treatments to patients. Recently, Steven R. Smith, M.D., was recruited as the TRI’s executive director, one of many new faculty brought to Lake Nona in 2009. Dr. Smith’s work bridges the gap between cellular and molecular biology and clinical care. His research is focused on obesity, diabetes and the metabolic origins of cardiovascular disease. Specifically, Dr. Smith investigates why some people burn fat when fed a fatty diet while others fail to burn fat and develop health problems like diabetes. He is also trying to understand how obesity leads to type 2 diabetes and examining the relationship between inflammation and diabetes. “We recently discovered that in some obese people, adipose (fat) tissue becomes hypoxic (starved of oxygen) because there are not enough small blood vessels,” says Dr. Smith. “This leads to inflammation in adipose tissue. There is a growing body of science that shows that inflammation is a major player in the development of type 2 diabetes.”
Dr. Steven R. Smith
On the clinical side, Dr. Smith wants to identify and validate drugs to treat obesity and diabetes. His translational work has demonstrated that everyone is unique at the molecular level, suggesting new ways to match therapies to the individual—in other words, personalized medicine. “One new area that I will be working on in Florida is using antiobesity drugs to treat diabetes,” says Dr. Smith. “We know that the first 10 to 15 pounds lost has a big impact on blood sugar control and metabolism. Many diabetes drugs cause weight gain. Since most people become diabetic because they are overweight, we believe that weight gain is not a desirable effect of diabetes drugs. Weight loss can also prevent the development of diabetes.”

Sanford Health are establishing an integrated, academic/pediatric research network. Recently, Sanford researchers from Sioux Falls and La Jolla met for the Second Annual Sanford Scientific Symposium to share their research and discuss how best to move forward with efforts to cure childhood diseases. Held at Burnham’s La Jolla campus, the symposium addressed the convergence of basic scientific and clinical research and how the collaborations between Burnham and Sanford Health could lead to new treatments. “This collaboration is working on many levels,” says Fred Levine, M.D., Ph.D., director, Sanford Children’s Health Research Center. “Scientists from Sioux Falls and Burnham are periodically comparing research findings. One scientist from La Jolla has been recruited to Sioux Falls, and others are applying for positions there. So we are developing the cross-pollination we hoped to achieve, and that will lead to new and important insights into childhood diseases.”

The Yamaguchi laboratory genetically modified the Has2 gene so that the gene can be conditionally disrupted in mice. This is the first time a conditional Has2 knockout mouse has been created, a breakthrough that opens vast possibilities for future research. Published in Development. José Luis M ill án, Ph.

When HPP patient “Baby Amy” was flown from her home in Ireland to Winnipeg, Canada, she was transported in an insulated box to prevent her bones from breaking. However, after receiving an enzyme replacement therapy developed by Dr. Millán and others, she was healthy enough to be held by her mother and make the trip home to Ireland.

Conrad Prebys Center for Chemical Genomics “The idea of saving just one life is remarkable, but the opportunity to use this technology to find cures that will affect millions of people, that’s incredible.” Conrad T. Prebys Conrad T. Prebys
I n Searc h of New Me d i cine s In 2001, Burnham leadership, as part of the Institute’s 10-year plan, decided to pursue the study of chemical genomics. This decision was not without risk, as creating the scientific infrastructure would require a large capital investment. On the other hand, the potential rewards were immense. Much of the science at Burnham involves asking important questions about how genes and proteins function. Chemical genomics is a powerful way to answer many of those questions. Now, eight years later, scientists at the Conrad Prebys Center for Chemical Genomics are carrying out the formidable task of finding chemical compounds that can alter protein function. Robotic screening systems test large chemical libraries (with nearly a half million compounds) against biological material—like a single protein or a specific type of cancer cell. These screens are intended to find the handful
of molecules that can regulate a specific gene or protein by turning it on or off. A chemical “hit” can have a number of uses. The ability to manipulate a protein can help researchers determine what that protein does. In some instances, a compound may have drug-like properties that can be optimized by medicinal chemists and pharmacologists and perhaps advanced to clinical trials. A Soun d Deci s ion Burnham’s expertise in chemical genomics has been recognized nationwide and has become a magnet for public and private investment. In September 2008, Burnham was awarded a $98 million grant to establish a comprehensive screening center as part of the National Institute of Health’s Molecular Libraries Probe Production Centers Network— one of only four such screening centers in the country. In early 2009, Burnham signed an assay development and license agreement with Johnson & Johnson
Pharmaceutical Research and Development (J&JPRD), Burnham’s first broad-based partnership with a large pharmaceutical company. Under this multi-year agreement, Burnham will provide J&JPRD with access to screening technologies to investigate drug targets for inflammatory diseases. In January 2009, Conrad Prebys donated $10 million to name the screening center. For Prebys, a longtime San Diego real estate developer, the decision to support chemical genomics was built on his desire

He is discussing Star Trek’s sophisticated hand-held medical devices and all they could do for patients. “Ideally, you would like to have a device like Dr. McCoy’s

that could both diagnose and treat,” says Dr. Ruoslahti. “I think eventually we will have devices like small MRI machines that can do just that.” Though this level of technology is still many years off, Dr. Ruoslahti is leading projects that might seem like science fiction. A former Burnham president and CEO, Dr. Ruoslahti established the Burnham connection to
The B urnham Repor t | www.burnham.org
UCSB in 2006. He is building on his earlier discovery that a peptide (a piece of protein) called RGD is attracted to cell attachment proteins called integrins. What makes this so important is that tumor blood vessels express RGD-binding integrins, allowing researchers to custom-make peptides that home in on tumors. Taking that a step further, Dr. Ruoslahti has been collaborating with engineers at UC Santa Barbara to build medicine-containing nanoparticles. By combining these two technologies, researchers hope to create therapeutic nanoparticles that home directly to a cancer and release their therapeutic payloads inside the tumor. “We have succeeded in putting targeting molecules on nanoparticle drugs and have shown that they are more effective and less toxic,” says Dr. Ruoslahti.
by researchers worldwide to selectively remove genes to study their functions in specific cells and tissues at specific times. But over time, Dr. Marth realized that there was more to cells than what DNA, RNA and proteins were teaching us. “We have been looking to genes to find the origins of disease,” says Dr. Marth, “but genomic variation has not explained the origins of many common grievous diseases, such as diabetes, autoimmune conditions and various neurodegenerative disorders.” When his research revealed that mechanisms responsible for at least some of these diseases were attributed
Filling in th e P uzzle Nanoparticles, like this micelle, may be the future of medicine. Jamey Marth, Ph.D., who directs the new to non-genetic alterations of joint Center for Nanomedicine cells, Dr. Marth began to see established by Burnham and things differently. UC Santa Barbara, began his “Genes and proteins are career studying genes. In fact, important, but cells are also he helped develop Cre-loxP made up of two other major technology, which is used structural components:
B u r n h a m t h e y e a r in tr a n s l a tion
glycans (sugars) and lipids (fats). We need to come to a better understanding of how they operate and malfunction in causing disease.” Dr. Marth notes that glycans and lipids are much more difficult to study because they are not template-driven.
What is
In other words, a specific sequence of DNA is a template for a specific sequence of RNA, which in turn creates a sequence of amino acids that build a protein. Lipids and glycans, on the other hand, are not so easy to trace. Dr. Jamey Marth “There will continue to be profound discoveries in the genome, but we’re going to miss things if we don’t look at the cell in a more holistic, rigorous way,” says Dr. Marth. “We need to develop highthroughput structural analysis of glycans and lipids so we can see inside that black box.
Nanotechnology is the best way to achieve this and incorporating these components more broadly into nanomedicine is expected to further enrich our current approaches to diseases that we still have trouble treating effectively.” A Marriage of Biologi st s an d Engineers One of the main reasons Drs. Ruoslahti and Marth set up labs at UC Santa Barbara was to take advantage of the university’s world-class engineering. “Because of my knowledge of homing peptides, engineers began approaching me about using this technology to help target nanoparticles,” says Dr. Ruoslahti. “I realized that molecular biology and chemistry have made great contributions to medicine, but we needed to do more. It was time to also focus on physics.”
When the UCSB-Burnham Center for Nanomedicine was created in summer 2009, it was built on the idea that fruitful collaborations between biologists, chemists, physicists, engineers and others could lead to amazing breakthroughs. “The typical approach has been to start from the biomedical side by cherry-picking a few talented engineers and moving them out of their comfort zone into a biomedical research environment,” says Dr. Marth. “But here we have done the opposite and started with an environment rich with superb engineers. We are creating a collaborative environment without walls between disciplines and that will lead to new approaches and new knowledge and will give us the best opportunities to develop needed advances in diagnostics and therapeutics for disease prevention, treatment and cure.”
Nanomedicine?
Rudolph Virchow, the father of pathology, noted that “all diseases are reducible to active or passive disturbances of cells.” Unfortunately, most medical technologies are designed to function more on the macro than the cellular level. Surgery deals with large masses of cells or entire organs. Many medicines, including chemotherapies, are delivered through the bloodstream and affect most of the body. Radiation, both for treatment and diagnosis, also works on a larger scale. On the other hand, biological research over the past 50 years
has focused on key parts of the cell, including genes and proteins. Nanomedicine seeks to redefine treatment and diagnosis by engineering microscopic devices with multiple functions to focus on the cellular roots of disease. Using impossibly tiny machines (some as small as a nanometer, one millionth of a meter), researchers and physicians hope to diagnose and treat cancer, diabetes and heart disease; repair tissue damaged by trauma; and diagnose life-threatening conditions on the cellular level, long before there are recognizable symptoms.

Greg Lucier knows biotechnology. As Chief Executive Officer of Life Technologies (the parent company of Invitrogen and Applied Biosystems), one of the world’s largest providers of systems, reagents and services to support biomedical research, Lucier understands what it takes to succeed in the laboratory. In fact, you can hardly turn a corner at Burnham without seeing Life Technologies products being used to perform critical experiments.

Lucier has been a Burnham trustee since 2005 and succeeded Malin Burnham as board chair in October. He chose to volunteer his time and effort at Burnham for several reasons. Naturally, the Institute provides a great complement to his “day job.” Lucier was also attracted to Burnham by the Institute’s strong leadership. “I have been really impressed by Dr. Reed, Dr. Vuori and others,” says Lucier. “I like working with the best, and Burnham has the best.” But most importantly, he is a fervent believer in the work that Burnham accomplishes every day.
The B urnham Repor t | www.burnham.org
“Basic research is the foundation for future commercial application,” says Lucier. “A developed country like the United States is morally bound to fund basic research because of the multiplier effect. Whether the multiplier is saving lives by curing disease, coming up with new methods to improve food production or finding new ways to make fuel from biological materials, this is critically important work.” A Busy Season Lucier takes over board leadership at a very hectic time. One of his first duties was helping dedicate Burnham’s new Lake Nona facility. “I was blown away by the excitement at Lake Nona,” says Lucier. “The facility looks great, but I was really impressed by how passionate the entire community is. Scientists, administrators, government leaders, local supporters—they were all ready to go.” In addition to opening the Lake Nona facility, Burnham expanded its presence at UC Santa Barbara and acquired new facilities on Torrey Pines Mesa. Lucier knows there is a great deal to be accomplished in the next few years, but feels
strongly that Burnham has the right people in place for continued success. Looking Forwar d In the coming years, Lucier sees Burnham playing a significant role in redefining how biomedical research is done. “I believe we are going to see new models for research,” says Lucier. “We have the opportunity to bring together universities, independent academic institutions, contract research organizations, pharmaceutical companies and other organizations to advance the science and bring us closer to new treatments. We are already seeing this kind of collaboration, both in La Jolla and Lake Nona, and it is our job to make sure we continue to expand those partnerships.” Lucier notes that he and the other members of the board of trustees are very excited about where Burnham is going. “Our role is to work with Burnham leadership to bring the organization to the next level, just as previous boards have done. We’re here to look after the short and long-term welfare of the institution through advice, financial support, moral support and good governance. This is an incredible moment in Burnham’s history, and I am very pleased to be a part of it.”

Her family home had been destroyed during a bombing raid and, at 17, she volunteered to be an ambulance driver. Later she became a military intelligence officer in the British Army. “All the men, including my brothers, had left home to fight for Britain,” says Siegel. “It was then I realized the need to give back.” Sascha Siegel and Lillian Fishman Siegel moved to the United States in the 1940s and built a family and Dr. Na i-Ying a career as a fashion designer and M ic h elle Yang, of television talk show host.

An
Amazing Year
As the year 2009 draws to a close, we reflect on our progress and take pride in the many accomplishments that have advanced our medical research mission, giving hope to those suffering from disease. By all accounts, 2009 has been a great year for Burnham. Multiple breakthroughs were made in our efforts to reveal the fundamental causes of disease and to develop innovative prototype therapeutics. This year, Burnham gained the top ranking in publication quality, with more citations per publication than any other organization worldwide in the fields of Biology and

In October, Malin Burnham stepped down as Board of Trustees Chair after a very successful two-year term, and Greg Lucier has assumed that position. He will help us develop our strategy for the next decade, as we near the end of our current 10-year plan and begin thinking about what’s next for Burnham. In 2009, we almost doubled our facilities, including opening our gorgeous and environmentally friendly building in Orlando, acquiring a large research building in San Diego, expanding our footprint in Santa Barbara and committing to occupy space in the Sanford Center for Regenerative Medicine building, soon to be under construction. Burnham is growing and prospering, thanks to much hard work and your support. Your generosity provides the seed capital that allows Burnham scientists and supporting professionals to excel at what they do best— great science. In turn, that science provides the basis to win the large research grants that fuel 80 to 90 percent of our biomedical research enterprise. With so much accomplished in 2009, and with your help, we look forward with great anticipation to advancing our medical research mission to new heights in 2010.
