Unconventional Genetic Strategy Could Enhance Production of Medical Treatments
Tuesday, March 23, 2021
We all have bad days on the job — your colleague keeps bugging you, your boss yelled at you for an innocent mistake, and you skipped lunch because you have 10 different deadlines coming up. Understandably, many people find it much harder to get their work done under such stressful circumstances. Microbes that produce chemicals for medicine and scientific research experience similar struggles, but a recent IRP study has found that short-circuiting their stress response makes them far more efficient at that task.
Inhibiting Energy Production Pathway Delays Tumor Formation in Mice
Tuesday, November 10, 2020
Despite the common misconception that sugary treats send kids bouncing off the walls, fat actually provides more than twice as much energy as sugar and other carbohydrates. This energy can be a double-edged sword, fueling not just healthy cells but also cancerous ones. A new IRP study in mice suggests that reducing the body’s ability to burn fat molecules for energy could slow the formation of tumors, potentially extending the lives of individuals with strong genetic predispositions to cancer.
Program Boosts Initiatives Supporting Researchers Across NIH

From Superbowl-winning football teams to comic book cohorts like The Avengers, combining the efforts of multiple talented individuals is a proven strategy for achieving remarkable results. It may come as no surprise, then, that the NIH’s Intramural Research Program (IRP) strongly encourages collaborations that breach the boundaries of its 24 Institutes and Centers. One example of these efforts is the Director’s Challenge Innovation Awards Program, which since 2009 has funded high-impact scientific projects that bring together researchers from across the IRP.
Mouse Study Supports Potential of Ketone-Elevating Treatment

Whether from candy, soda, or fruit, sugar is the preferred source of sustenance for many people, and also for their brains. However, in patients with Alzheimer's disease, brain cells are less capable of turning sugar into energy. New IRP research provides evidence that this problem and the cognitive symptoms it causes could be partially solved by providing the brain with an alternative fuel.
Volunteering for Studies Allows Me to Help Myself and Others

Watching my dad carry the luggage to the car has become an all-too-familiar sight. It’s time for my mom and me to head to the NIH again, another trip in a lifelong journey for answers. I give my dad a long hug goodbye, and then I watch him stand alone in the driveway as we back away. The gravel arduously aches and crunches under our tires, a sound as uncomfortable as my symptoms even on my good days — few as there are.

The more scientists have learned about the community of benign bacteria inside our bodies, known as the microbiome, the more effort they have put into recruiting it in the fight against disease. What’s more, scientists occasionally discover that treatments long thought to work completely independently of our native microbes also relieve symptoms by interacting with them. New IRP research into the most commonly used medication for type 2 diabetes has led to just such a revelation by demonstrating that its benefits stem in part from its ability to kill off a particular species of bacteria in the human digestive tract.

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.”

Last month I moderated our annual retreat with the NIH Scientific Directors, those individuals tasked with leading their Institute or Center (IC)-based intramural research program. We were joined by many of the IC Clinical Directors. And this year we decided to do something a little different: listen to a series of talks about exciting, new IRP research.

Many scientists at the NIH used the metabolic chamber—a room constructed as a scientific instrument in which volunteers could live—to study how our bodies use air, food, and water under different conditions. Would you have volunteered for a study? Today's NIH Intramural investigators have even more advanced technologies to learn about energy expenditure's affects on obesity.

The solution to obesity seems simple on the surface—fewer calories in, more calories out—but for those who have tried to lose weight, it's usually not an easy task, partly because weight is the product of many interrelated factors: environment, family history and genetics, behavior, metabolism, and others. Investigators at the NIH Intramural Research Program (IRP) are studying all of those aspects and more to further understand the disease and better inform public health initiatives.
