Modified Hormone Protects Damaged Hearts

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.

IRP’s Michael Gottesman Elected to National Academy of Sciences

NIH Investigator Recognized for Insights into Drug Resistance in Cancer

Dr. Michael Gottesman

The National Academy of Sciences, a private society established in 1863, is made up of the United States’ most distinguished scientific scholars, including nearly 500 members who have won Nobel Prizes. Members of the NAS are elected by their peers and charged with the responsibility of providing independent, objective advice on national matters related to science and technology in an effort to further scientific innovation in the U.S.

IRP Senior Investigator Michael Gottesman, M.D., is one of four IRP researchers who were elected to the Academy over the past two years. At the NIH, Dr. Gottesman plays two very different but equally important roles, serving as Deputy Director for Intramural Research while also leading the Laboratory of Cell Biology at the National Cancer Institute (NCI).

Postbac Life: A Week in an IRP Lab

What does a postbac actually do in the NIH IRP? Maybe you have an image of someone mixing colorful chemicals together like a mad scientist (which sometimes isn’t too far from the truth).

Although I am not creating any diabolical concoctions, I am kept quite busy running tests to examine whether our treatments reverse the effects of lung fibrosis, a thickening and scarring of lung tissue. Here’s what a typical week looks like for me.

Postbac Life: Wading Into Drug Discovery Research

“That machine? You’re gonna have to get up close and personal with it,” Josh, my fellow postbac, told me. I looked at this small metal contraption and nodded, trying to appear as if I understood, while thinking: he just means that people spend so much time sectioning organs on the microtome that it’s like spending an extended amount of time with a loved one, right?

Fast forward a few days, and I find myself breathing warm, moist air onto a paraffin-embedded mouse lung to soften the wax, just before I slice four-micrometer sections of mouse lung tissue that will later be stained and examined under a microscope. “He wasn’t kidding,” I muttered.

Life of a Postbac: My Experience Joining the NIH Family

It was picture day, and I sat stiffly in front of a wrinkly blue curtain, nervously patting my hair into place. “You can smile, but just make sure no teeth are showing,” the person taking my picture told me. I laughed at that, and she also laughed, adding, “Everyone gets a good chuckle out of that one,” as she snapped my photo. A few days later, I picked up my photo, printed (not so) nicely with a vertical stripe running down my face. I didn’t even notice. I thought, this is real, as I proudly held up my official NIH ID badge.

Repurposed Drugs Could Curb Cancer Drug Resistance

Much of the time, new therapies are built from the ground up, with researchers closely scrutinizing a specific molecule or cellular process and designing compounds that can influence it. In some cases, however, scientists take the opposite approach, throwing a multitude of therapeutic darts at the disease dartboard to see what sticks, and then working backwards to unravel why a drug was effective. IRP researchers recently used this method to identify potential treatments for drug-resistant ovarian cancer and determine how some of those tumors become impervious to a particular chemotherapy.
