Mouse Study Points to Approach for Preventing Diabetes-Related Heart Failure
Tuesday, June 7, 2022
Our cells love to lap up sugar from our blood, but as is often the case, too much of a good thing can cause problems. In people with diabetes, chronically high blood sugar can harm organs, including the heart. In an effort to combat this life-threatening problem, IRP researchers demonstrated in mice that activating a specific biological pathway in heart cells can reduce diabetes’ damaging effects on the vital organ.
IRP’s Ph.D. and Medical Students Present Research at Virtual Event
Thursday, March 10, 2022
The IRP isn’t concerned only with discovering the secrets of how our bodies work and developing new therapies to treat disease. Senior scientists and many other employees at NIH also are actively involved in training the next generation of researchers. One place where the benefits of those efforts is strikingly clear is at NIH’s annual Graduate Student Research Symposium, where graduate students performing research in NIH labs show of the fruits of their partnerships with IRP researchers.
On February 16 and 17, more than 100 of the IRP’s graduate students presented their work virtually at the 18th edition of the event. These young scientists discussed the results of studies on a huge range of topics, from how hunger changes during pregnancy to how viruses cause cancer. Read on to learn about a small sampling of the projects they’ve been hard at work on.
Custom-Built Molecule May Improve On Its Natural Counterpart
Monday, February 22, 2021
Ten years ago, a young woman from Chicago came to the National Institutes of Health with a rare genetic condition. A mutation in her DNA was making her metabolic system malfunction, causing levels of fat molecules called triglycerides in her blood to skyrocket far out of the normal range. This triggered inflammation in her pancreas, a painful and potentially life-threatening condition known as pancreatitis. She couldn’t understand why there wasn’t any kind of treatment to help her.
IRP senior investigator Alan T. Remaley, M.D., Ph.D., took on the challenge with the help of Anna Wolska, Ph.D., a research fellow in his lab. Dr. Remaley leads the Lipoprotein Metabolism Section in the National Heart, Lung, and Blood Institute (NHLBI), where he and Dr. Wolska study lipoproteins, small particles that transport fats such as cholesterol and triglycerides through the bloodstream to be broken down and used by cells for energy. Their efforts to help that young woman ultimately led to the discovery — published last January — of a new strategy for reducing triglycerides in order to treat serious ailments like pancreatitis and heart disease.
Alteration Helps Prospective Drug Persist Longer in Rodents’ Bodies

Even the best construction crew cannot repair a building if it is called away from the site before it can begin its work. Similarly, while the body’s ability to cleanse itself of chemicals can prevent the buildup of toxins, it can also stymie the therapeutic effects of medications. IRP researchers recently found that modifying a prospective treatment for heart failure to help it persist longer in the body boosted its beneficial effects in mice.

The IRP has been home to a number of truly remarkable scientists who spent decades making discoveries and developing technologies that would go on to improve the lives of many. One of these giants was Theodor Kolobow, M.D., who passed away in March of last year at age 87. During his many years at the NIH's National Heart, Lung, and Blood Institute (NHLBI), Dr. Kolobow made momentous contributions to the study of our lungs and cardiovascular systems, including advancements in the development of artificial organs and key insights into the biological processes behind acute lung injury.
Dr. Kolobow's legacy lives on not only through his colleagues' fond memories and his lasting influence on medical practice, but also through the NIH's historical archives. Read on for a tour through Dr. Kolobow's life and career, as can only be told by the Office of NIH History.

Sometimes as a museum curator, I come across a box in the collection with a vague marking and full of bits and pieces of … something. One of the coolest things is finding out what that something was and who created it. This photo shows pieces from the NIH lab of Dr. Stanley Sarnoff, dating from 1954-1962.

Using real-time MRI, Dr. Keith Horvath's group at the NIH's National Heart, Lung, and Blood Institute (NHLBI) can precisely implant a replacement porcine heart valve using a collapsible stent more safely and quickly than with standard techniques.
"The reason for using [real-time] MRI is three-fold," Dr. Horvath explains...
