Hepatology 2021 Mar 13. Epub 2021 Mar 13.

Department of Cardiology, The First Affiliated Hospital, School of Medicine, Zhejiang University.

Characterized by hepatocyte steatosis, inflammation, and fibrosis, nonalcoholic steatohepatitis (NASH) is a complicated process that contributes to end-stage liver disease and, eventually, hepatocellular carcinoma (HCC). Tumor necrosis factor alpha (TNF-α)-induced protein 8-like 1 (TIPE1), a new member of the TNF-α-induced protein 8 family, has been explored in immunology and oncology research, but little is known about its role in metabolic diseases.
