A mutant or damaged gene may be a cause of a severe, mysterious form of nonalcoholic fatty liver disease, University of Illinois Urbana-Champaign researchers have found. Mice and human liver cells lacking the SRSF1 gene show all the hallmarks of nonalcoholic steatohepatitis, also known as NASH, the researchers found.

When Auinash Kalsotra (CGD/GNDP), member of the Cancer Center at Illinois, Associate Professor and the William C. Rose Scholar of Biochemistry, attended college at Birla Institute of Technology and Science in India, he knew he wanted to pursue an entrepreneurial career inspired by his family members. Instead of following a traditional business route, Kalsotra’s enterprising genes have led him down a trailblazing scientific journey – uncovering intricacies of cell biological mechanisms that may lead to more targeted and improved cancer therapies.

The liver has a rare superpower among body organs – the ability to regenerate, even if 70% of its mass is removed. It also keeps up its metabolic and toxin-removing work during the process of regeneration, thanks to a subset of cells that expand their workload while the rest focus on multiplication, a new study in mice found.

Roughly 80% of people with myotonic dystrophy – a common form of muscular dystrophy – experience dangerous heart ailments, and heart rhythm defects are the second-leading cause of death in those with the condition. In a new study, researchers traced the molecular events that lead to heart abnormalities in myotonic dystrophy and recreated the disease in a mouse model.

They report their findings in the journal Developmental Cell.

In Greek mythology, Zeus punishes the trickster Prometheus by chaining him to a rock and sending an eagle to eat a portion of his liver every day, in perpetuity. It was the right organ to target – the liver has the ability to regenerate itself, though not overnight nor for eternity.

The grant to Prof. Kalsotra provides $300,000 over a three-year period to study the molecular basis for cardiac arrhythmias in Myotonic Dystrophy, a multi-systemic disease that affects about 1 in 8000 people with no cure.

The heart is a dynamic muscle that grows and shrinks in response to stressors such as exercise and disease. The secret to its malleability lies in individual cells, which get bigger or smaller depending on the heart’s needs. A new study of mouse hearts reveals a previously unknown mechanism by which heart cells control their size by ramping up or stopping the production of a key factor called PABPC1.
