At lunchtime last Wednesday, the NIH Clinical Center’s FAES Terrace echoed with the joyful sounds of scientists nourishing their bodies and their brains. While those stopping by the annual NIH Research Festival poster session could be forgiven for making a beeline straight for the food — including the submissions to this year’s Scientific Directors’ baking competition — once their plates were full, they took advantage of the opportunity to satiate their scientific curiosity as well by checking out the dozens of posters on display.

The NIH’s main campus in Bethesda, Maryland, may have the look and feel of a university campus, but the world-renowned research institution does not grant credentials like an M.D. or Ph.D. Instead, the Graduate Partnerships Program offers graduate students from schools around the world the opportunity to complete research for their Ph.D. dissertations in IRP labs while pursuing advanced degrees from their ‘host’ institutions.
Potential biomarker may contribute to personalized treatments

Until recently, medical treatment has largely been one-size-fits-all, with doctors unable to separate patients into distinct groups that might benefit more or less from a particular approach. However, researchers are increasingly finding that individuals with the same disease can differ markedly in ways that might one day influence their care. A recent IRP study has identified a particular molecule that may have just such an impact for patients with damaged lungs.

Food companies have long marketed carbohydrate-rich drinks and energy bars to athletes with the message that the energy those snacks provide is key to lifting heavier and running farther. A new mouse study by IRP researchers, however, suggests that skipping a meal (or several) might be far more effective for increasing athletic prowess1.
Unlike modern Americans used to three square meals a day, our ancient ancestors couldn’t exactly throw a TV dinner in the microwave whenever they felt a bit peckish. As a result, they probably found themselves hunting wooly mammoths and fending off saber-toothed tigers on an empty stomach.
“From an evolutionary perspective, animals in the wild – particularly predators – need to be able to function at a high level when they’re in a food-deprived state,” says IRP Senior Investigator Mark P. Mattson, Ph.D., the study’s senior author. “Individuals who were able to perform at a high level in a fasted state had a survival advantage.”

Dr. Hong Xu's team’s expertise in mitochondrial DNA genetics, along with a strong mitochondrial biology research group in the IRP, allowed them to solve the fundamental biological question of how organisms are able to stop the accumulation of mitochondrial DNA mutations from being passed on to future generations.

Mitochondria are dynamic cellular organelles involved in ATP synthesis and in apoptotic mechanisms (programmed cell death). However, in addition to these classically known functions, recent studies at the NIH have deciphered another intriguing role for mitochondria in the development and plasticity of neurons.
