PARK7 deficiency inhibits fatty acid β-oxidation via PTEN to delay liver regeneration after hepatectomy.

ABSTRACT:

Background & aims

Transient regeneration-associated steatosis (TRAS) is a process of temporary hepatic lipid accumulation and is essential for liver regeneration by providing energy generated from fatty acid β-oxidation, but the regulatory mechanism underlying TRAS remains unknown. Parkinsonism-associated deglycase (Park7)/Dj1 is an important regulator involved in various liver diseases. In nonalcoholic fatty liver diseased mice, induced by a high-fat diet, Park7 deficiency improves hepatic steatosis, but its role in liver regeneration remains unknown METHODS: Park7 knockout (Park7^-/- ), hepatocyte-specific Park7 knockout (Park7^△hep ) and hepatocyte-specific Park7-Pten double knockout mice were subjected to 2/3 partial hepatectomy (PHx) RESULTS: Increased PARK
