PIAS2 Overexpression Attenuates Erastin-Induced Ferroptotic Changes and Is Associated With Increased GPX4 Protein and Enhanced GPX4-Related SUMO3 Signaling in Hepatocellular Carcinoma Cells.
BACKGROUND Protein inhibitor of activated STAT 2 (PIAS2) is highly expressed in various solid tumors. Its precise function as a ferroptosis regulator in hepatocellular carcinoma (HCC) is still unknown. The purpose of this work was to determine whether PIAS2 overexpression attenuates erastin-induced ferroptotic changes...
