It is a major risk factor for cirrhosis and liver cancer. And because treatment options are limited, MASH is the second leading cause for liver transplants in the United States after cirrhosis caused by chronic hepatitis C infection. A better understanding of the pathological processes that drive MASH is critical to creating effective treatments. In a new paper published August 19, 2024 in PNAS, a team of scientists from Sanford Burnham Prebys, the University of California San Diego School of Medicine and elsewhere, describe the complex interplay between diseased liver cells and macrophages -- a type of white blood cell whose jobs include killing and removing harmful cells and pathogens and helping to spur normal healing.

The new study shows that this protein also supports the maintenance of heart structure and function, but when it is overactive it causes thickening of the heart muscle, which is associated with heart disease.

In a new study published in the journal Nature Cancer, first author Sanju Sinha, Ph.D., at Sanford Burnham Prebys, with senior authors Eytan Ruppin, M.D., Ph.D., and Alejandro Schaffer, Ph.D., at the National Cancer Institute--and colleagues--describe a first-of-its-kind computational pipeline to systematically predict patient response to cancer drugs at single-cell resolution.

By studying the conversation among the liver, the immune system, heart and kidneys, Dhar hopes to discover signals that could be used to detect metabolic disorders, especially metabolic-associated steatohepatitis (MASH), and liver cancer much earlier, when they're easier to treat.
