Dr. Zigman finds ghrelin affects exercise and food intake
The hormone ghrelin and its receptor influence both exercise endurance and food intake following exercise, new research from UT Southwestern indicates. “Circulating ghrelin concentrations increase as an adaptation to counter metabolically and behaviorally stressful environments. Our results suggest that exercise is another condition that raises levels of the hormone,” said Dr. Jeffrey Zigman, senior author of the study.
Liver cancer screening rates must improve
Patients with cirrhosis should be screened regularly for liver cancer, though few are – in part because busy physicians often don’t order the screening tests, said UT Southwestern oncologists.
“The frequency of liver cancer is increasing rapidly in the U.S. and liver cancer-related mortality has nearly doubled over the past decade. The poor prognosis of the disease is largely driven by the failure to diagnose the disease at an early stage,” said Dr. Amit G. Singal, Medical Director of the Liver Tumor Program at UT Southwestern’s Harold C. Simmons Comprehensive Cancer Center.

Dr. Levine's prescription for life
Exercise can reverse damage to sedentary, aging hearts and help prevent risk of future heart failure – if it’s enough exercise, and if it’s begun in time, according to a new study by cardiologists at UT Southwestern and Texas Health Resources. “Based on a series of studies performed by our team over the past 5 years, this ‘dose’ of exercise has become my prescription for life,” said senior author Dr. Benjamin Levine, Director of the Institute and Professor of Internal Medicine at UT Southwestern.
Drs. Courtney and Brugarolas publish finding on HIF-2a inhibitors
Metastatic kidney cancer remains largely incurable. Despite a dozen treatments and several immunotherapies, survival rates beyond 5 years remain around 10 percent. A study published in the Journal of Clinical Oncology reports initial findings with a novel drug belonging to a new class of medicines called HIF-2a inhibitors that show promise in treating metastatic kidney cancer.
