Non-alcoholic fatty liver disease (NAFLD), commonly known as fatty liver disease, is a prevalent disease frequently seen in obese people. Having high fat content in the liver is detrimental, as it is strongly associated with severe health problems like diabetes, high blood pressure, and liver cancer. A research team led by Dr. Chi Bun Chan, Assistant Professor from the School of Biological Sciences, Faculty of Science, the University of Hong Kong (HKU), has uncovered a new protective mechanism against this disorder. The research findings have recently been published in the world-leading scientific journal Hepatology.
