NEWSLETTER OF THE INSTITUTE FOR RESEARCH IN BIOMEDICINE

Building the architecture of life

IRB Barcelona gets on the project leadership bandwagon

2009 will be a busy year for some IRB Barcelona PhD students. At least until November 2-3, when the first IRB Barcelona PhD student symposium, ‘The Architecture of Life,’ is scheduled to take place.

IRB Barcelona has been granted the coordination of two European projects, making the Institute a leader in Spain, together with the Spanish National Research Council. The EC will grant IRB Barcelona funding of more than 5 million euros from 2009 to 2011.

Staff at the newly created Advanced Digital Microscopy Core Facility have been busy these past months purchasing a wide range of advanced microscopes, which will be soon fully operational to support IRB Barcelona researchers.

“Our mission is to look for outstanding speakers. The good news is that some of our top choices have already confirmed. The program is ambitious in that it will cover numerous facets of the architecture of life. Sessions will include DNA and RNA, as well as proteins and cells and up to entire tissues and organisms.”

“After months of negotiations, we've managed to reach an agreement with CosmoCaixa to host the symposium for us. We work as the liaison between the museum and IRB Barcelona, and deal with all the venuerelated aspects, including room allocation, poster session coordination, catering and communications.”

“We're scientists, but we're not scared of finances!

Working on budget details is a bit tedious, but definitely worth it as a learning process. It's a skill that will help us in our future careers.

AWARDS & HONORS

FACES TO NAMES

Awarded for breakthrough research on metastasis

Alan Smrcka. Visiting professor, IRB Barcelona group on

IRB Barcelona Adjunct Director Joan Massagué received on December 13 the “Outstanding Investigator Award for Breast Cancer Research” given by the American Association for Cancer Research (AACR). Massagué was selected for this award for the impact of his studies on the metastasis of breast cancer to the lung. A leading expert in cancer metastasis and head of the Cancer Biology and Genetics Program at the Sloan Kettering Cancer Center in New York, Massagué has devoted more than twenty years to elucidating the role of the TGFBeta protein in cell growth and division.

“Many great ideas in science are processed in the subconscious”

The research carried out by IRB Barcelona Principal Investigator Miquel Pons recently passed the critical eye of a panel of more than one hundred evaluation experts. ‘La Marató de TV3 Foundation’ selected Pons on November 25 to head a three-year research study on key proteins linked to abnormal heart growth. The Foundation will devote more than 7 million euros to fund a total of 26 research projects that address cardiovascular diseases.

Among the most influential IRB Barcelona Director and Adjunct Director Joan Guinovart and Joan Massagué made it for a fourth consecutive year into the ranking of the top 25 most influential scientists in Spain, published this January by the Spanish newspaper El Mundo. Guinovart was chosen for his pioneering work on diabetes and neurodegenerative diseases, and Massagué for his breakthrough research on metastasis.

Green light to study key proteins in heart diseases

Design, Synthesis and Structure of Peptides and Proteins

ANNA ALSINA

Alan Smrcka (New York, 1958) has taken a break from his teaching and research duties at the University of Rochester to spend a sabbatical year working at IRB Barcelona in the Design, Synthesis and Structure of Peptides and Proteins group. A professor in pharmacology, physiology, oncology, biochemistry and biophysics, he was honored by the Wilmot Cancer Center in 2007 for his research into protein and cell interactions targeting new therapies for cancer and heart diseases.

- Why Barcelona for your sabbatical year?

“My wife and two children wanted to go somewhere out of America where we could get not only a scientifically enriching experience but also a cultural one. I started looking at the type of research that was being done in Barcelona with the idea that if I couldn't find really good science, we wouldn't take the step. I came across Ernest Giralt's work at IRB Barcelona, and I was very impressed with what I saw. It put to rest any reservations I had about leaving my own lab.”

- For instance?

Alan Smrcka (left) during the interview in the PCB Cafeteria.

- That's quick ...

“The secret in science is to be excited about what you're doing to keep your motivation going. You shouldn't give up just because it gets tough.”

- Have you ever given up?

“Sometimes you have no choice. When you get stuck for too long you have to be willing to give up on certain short-term goals to find your way around and get to where you want it to go.”

“Mainly to do cutting-edge research and be - How do you get the overall picture when able to take new research ideas back home.” all you have is scattered data?

- Is one year enough time?

“I'm a strong believer that many great ideas “My goal is to develop a new method for looking at G-protein dynamics through mass spectrometry and amino spectroscopy in order to target heart diseases, inflammation and pain medication. I think there's a really good chance of succeeding. We have already very exciting data showing that the methods we're using will work.”

in science are processed in the subconscious outside the lab, when you stop focusing about specific problems you have to solve.

It's happened to me a number of times to have come up with keen ideas after subconsciously thinking about them. Even when I'm sleeping the scattered data I've collected in the back of my head is being processed!”

IN BRIEF

NEWS FROM THE PARK

Team building in the cold More than thirty researchers from the IRB Barcelona Molecular Programme traveled to Vall de Núria in the Pyrenees at the end of October to spend two days together. The reason? The annual programme retreat, a team-building activity conceived to promote interaction among the research groups, as well as exchange of ideas and scientific goals. Full days of science were combined with time off to enjoy the mountains and breathe clean air.

Special guest editor for SEBBM IRB Barcelona press officer Sònia Armengou recently put her journalistic and editing skills to work by contributing to the December issue of the Spanish Society for Biochemistry and Molecular Biology (SEBBM)'s magazine. Invited as a special editor, Sònia coordinated and edited the journal's special section dedicated to Women in Science.

The calm after the fire IRB Barcelona Director Joan Guinovart crossed the Atlantic ocean to visit the construction site of the Faculty of Sciences at the Austral University of Chile on November 20. Invited by the vice-chancellor as a token of thanks for the continued support received from IRB Barcelona, Guinovart took a guided tour of the facilities to see the reconstruction work with his own eyes. The last time he had visited the university was in December 2007, soon after the ferocious fire had devoured the faculty.

SPOTLIGHT Stars for a day

I

RB Barcelona researchers Laura Nocito, Marc Liesa and Dèlia Zafra proved to be good at handling the pressure of being filmed on November 7.

Their mentoring experience to students who had carried their research project at the Institute was chosen to be part of an online video library of interviews and educational material for a new web channel the Ersilia Foundation will release this February. The three researchers spent over two hours with the Ersilia team answering questions in front of the camera.

NEW AT IRB BARCELONA Zhanna Shcheprova (Russia, 1981) has recently moved from Switzerland to Barcelona for personal and professional reasons.

Her decision to choose the Cell Division Laboratory at IRB Barcelona to work as a postdoctoral fellow was motivated by the lab's research direction and the working atmosphere. Her challenges are now to get familiar working with Drosophila in order to study the mechanisms of rejuvenation and achieving immortality in certain types of cells. There's no doubt she's qualified to dig into this area of research. Zhanna's work on rejuvenation in yeast during her PhD studies was so impressive that it made it into Nature magazine last year.

Katharina Kreymborg (Germany, 1980) decided not to move to the United States to work as a postdoctoral fellow because she was convinced that research possibilities in Europe were very strong. A biologist with a PhD in neuroimmunology, she has recently joined Eduardo Soriano's research group at IRB Barcelona attracted by the wide range of areas of expertise within the laboratory, and also by the challenge of working for the first time in her life in the field of neurology.

Sònia Saborit (Spain, 1975) has proven to be good at dealing (Front) Marc Liesa and his two students were the first ones to stand in front of the camera. In the background, Dèlia (right) and Laura (second right).

- What was the filming experience like?

“We were a bit shy at first—it was the first time we were taped and interviewed together! It turned out to be a fun and original experience to take a break from our routine.”

- What kind of questions were you asked?

“They digged into the details and conclusions of the research work carried out by the students we had mentored as part of the PCB programme ‘Tutoring for Secondary School Students.’

- What have you learned from tutoring?

“Participating in this kind of initiative has helped us to improve our teaching skills. It's very rewarding to see how students show interest and get excited about the learning process.”

- What's your advice for students?

“The key to enjoy and succeed in their work is to choose a subject they really like, always ask a lot of questions, and keep in mind that patience is the key, as experiments don't always work at first.”

with walk-in appointments. Since she started her new position as Project and Grant Officer in November, many IRB Barcelona researchers have stopped by her desk searching for answers about project and grant applications. Sònia is in charge of disseminating grant calls and providing support in funding applications, drawing up internal procedures for project evaluation, and coordinating institutional grants. She holds a degree in Philosophy and a Master of Business Administration, and carries many years of experience in project management for research centers in Barcelona.

ON THE MOVE David Vilchez (Spain, 1978) has made a new year's resolution: the commitment to change his lifestyle. After five years of work toward his thesis in the Metabolic Engineering and Diabetes Therapy group, he's now moving to San Diego to work as a postdoctoral research associate at the Salk Institute. He's leaving with mixed feelings about saying goodbye to his coworkers and optimism about what the future holds. “Some times stirring up life is good for career advancement in science,” he says.

Marc Liesa (Spain, 1981) will be moving abroad in March to start new research work at the Boston University Medical Center. He sees his change as an opportunity to complete his training as a scientist in a city known for its high level of research activity per square kilometer. He's leaving IRB Barcelona with his Doctor title under his arm after having successfully completed his thesis on the role of mitochondrial dynamics under the supervision of Principal Investigator Antonio Zorzano.
