Sites of Translation: Unraveling the Genes of Barbados
It’s hard to define a “typical day” working for the Barbados Nutrition Study—and that isn’t a bad thing. This internship allows me to work in three different locations: Dr. Galler’s office in Brookline, Judge Baker’s Children Center in Mission Hill, and UMass Medical School in Worcester. Aside from the newly-increased MBTA fares, the change in scenery keeps things interesting and exciting. Even more importantly, working in multiple environments has made the
connection between an evolutionary perspective and global health clearer to me.
Dr. Galler’s office basement holds towers of data since the 1970s, from teacher assessments of post-malnourished children to the psychiatric clinical interviews of those same kids later as adults. My two co-workers and I are working on organizing this data and making sense of it for future papers. It’s actually quite enlightening sifting through this history; we’ve seen some interesting commentary on people potentially undiagnosed with some mental or heart disorder. Here, the connection between the papers I’ve read and the Barbadian people come alive. Collectively, those musty, yellowed pages reveal the lasting impact of child malnutrition. The truth is, this impact goes beyond the sad infomercials about starving boys and girls

Here, the connection between the papers I’ve read and the Barbadian people come alive. Collectively, those musty, yellowed pages reveal the lasting impact of child malnutrition. The truth is, this impact goes beyond the sad infomercials about starving boys and girls
in developing countries. Starvation at that critical point of development means dire consequences into adulthood, even after the child is rehabilitated to a normal weight early on. It affects the child’s mind, health, family relationships, and future ability to make a living—so the
cycle of child malnutrition and adult poverty continues.
Judge Baker’s Children Center is the main center where Dr. Galler conducts her research and her collaborating teams meet. My specific project is to link nutrition and epigenetics to mental health. Two questions asked by the Barbados Nutrition Study are whether perinatal malnutrition can lead to mental disorders and what the epigenetic mechanisms are. To answer these questions, we look at the Barbadian cohort data that has already been collected. We’re also deciding on genes to study (that’s my job!) in malnourished and stressed rats. Hopefully we will then examine these genes in blood samples of the Barbadian cohort. So far, I’ve researched genes that are up- or down-regulated in conditions like ADHD or schizophrenia. But it’s harder to find studies on malnourished rats, or even on a human population that went through a brief famine. Apparently the connection between nutrition and the brain is not a highly-researched topic.
Finally, I am working with Dr. Galler’s phD student, Ana, at the UMass lab. Traveling there takes up most of my day, but once I arrive, I learn the technical procedures of the rat studies. Their brains are already harvested and separated, so we perform Western blot and ChIP DNA experiments to see which proteins of the genes we’re studying are expressed in stressed and malnourished rats.
In my previous post, I mentioned my interest in child malnutrition and the resulting adult complications with obesity and chronic diseases. The evolutionary reasons for this are not new, and in a way the hypothetical connection makes sense (search Developmental Origins of Health and Disease). Learning about malnutrition’s link to mental and neurological diseases adds a whole new element. These additional consequences of malnutrition make it even more difficult to lift oneself out of poverty through education—a very important issue in developing countries. Granted, Barbados has done quite well over the decades, and, today, hardly anyone is starving. But the effects of past starvation still remain. It will be very interesting to see what happens in generation two, the children of the original previously malnourished children…

About the Blogger
| Riana Balahadia is studying Human Evolutionary Biology with a secondary in Global Health & Health Policy and pre-med in Kirkland House at Harvard (class of 2014). During the semester she enjoys singing with the Veritones, a premier co-ed a capella group, and planning activities for Harvard Philippine Forum and the Undergraduate Global Health Forum. This summer she will be living in Winthrop as part of the SURF (Summer Undergraduate Research Fellowship) Program hosted by the Global Health Institute. Her mentor is Dr. Janina R. Galler, who has been working on the Barbados Nutrition Study (BNS) for the past 40 years. Riana's primary research will be on linking malnutrition and epigenetics to mental health, and then comparing that information with the BNS cohort in Barbados. She plans on listening to awesome music during her commutes to Judge Baker's Children Center in Mission Hill, Dr. Galler's office in Brookline, and the epigenetics lab in U Mass Medical School in Worcester. "Scientista is an invaluable resource for young women pursuing careers that traditionally represent few females. Not only does it provide connections and inspiration, it also offers a voice to new, female scientists. The women on Scientista send a positive message saying, "Yes! You can succeed in the hard sciences because she did too." - Riana Balahadia |
