Research presented today by UT Southwestern cardiologists at the annual American Heart Association (AHA) Scientific Sessions 2020 showed that Black and Hispanic people were more likely to be hospitalized with COVID-19 than white patients, and that nonwhite men with cardiovascular disease or risk factors were more likely to die.

As you drift into unconsciousness before a surgery, general anesthetic drugs flowing through your blood are putting you to sleep by binding mainly to a protein in the brain called the ɣ-aminobutyric acid type A (GABAA) receptor.

An autoimmune side effect of immune checkpoint inhibitor (ICI) drugs could signal improved control of kidney cancer, according to a new study by researchers in UT Southwestern’s Kidney Cancer Program (KCP).

A team led by UT Southwestern has derived a new “intermediate” embryonic stem cell type from multiple species that can contribute to chimeras and create precursors to sperm and eggs in a culture dish.

Ralph DeBerardinis, M.D., Ph.D., a professor at the Children’s Medical Center Research Institute at UT Southwestern (CRI), has been elected to the National Academy of Medicine (NAM), one of the highest honors in the fields of health and medicine.

Mice fed diets high in sugar developed worse colitis, a type of inflammatory bowel disease (IBD), and researchers examining their large intestines found more of the bacteria that can damage the gut’s protective mucus layer.

UT Southwestern researchers have discovered a mechanism that cells use to degrade microRNAs (miRNAs), genetic molecules that regulate the amounts of proteins in cells.

About half of all tumors have mutations of the gene p53, normally responsible for warding off cancer. Now, UT Southwestern scientists have discovered a new role for p53 in its fight against tumors: preventing retrotransposons, or “jumping genes,” from hopping around the human genome.

Less than three weeks after getting on an organ transplant list for HIV-positive patients, John Welch got the call. A liver was available from a deceased donor, and it was an excellent match.

Restricting calories has long been recognized as a powerful way to live longer, with periods of intermittent fasting proving more effective than a steady diet. However, the mechanism behind this phenomenon has been unclear.
