New study uncovers potential treatment for non-alcoholic fatty liver disease

NAFLD encompasses various metabolic diseases such as fatty hepatitis and cirrhosis resulting from excessive fat accumulation. Despite its prevalence, effective treatments for NAFLD have been limited. However, this groundbreaking research sheds light on potential therapeutic approaches.

Through animal experiments conducted on rats, the research team demonstrated that Thrap3 directly binds to AMPK within the liver. This interaction prevents AMPK from translocating from the nucleus to the cytoplasm and impairs autophagy -- a process crucial for breaking down triglycerides and reducing cholesterol levels. In essence, inhibiting Thrap3 expression presents a promising avenue for effectively treating NAFLD.

"We have encountered significant challenges while developing treatment strategies for non-alcoholic fatty liver disease. However, our discovery of the Thrap3 gene provides us with an effective method to tackle this condition," commented Professor Choi.

Additionally, it was confirmed that suppressing Thrap3 expression effectively improves non-alcoholic steatohepatitis -- an inflammatory disease stemming from fatty liver.

Supported by funding from Korea Research Foundation under the Ministry of Science and ICT, National Mouse Phenotype Analysis Group (KMPC), and UNIST Future Lead Project; this research was published online on August 1st in Experimental and Molecular Medicine. Professor Jang Hyun Choi, alongside Professor Sung Ho Park, served as corresponding authors of the paper, with Dr. Hyun-Jun Jang and Dr. Yo Han Lee from the Department of Biological Sciences at UNIST participating as co-authors.
