MAPK8 and Hepatic fibrosis: Tumor necrosis factor superfamily 14 (TNFSF14), highly expressed in the context of fibrosis, binds to the lymphotoxin β receptor (LTβR) and activates JNK signaling, thereby regulating TGF-β1 expression, which can contribute to liver fibrosis in vitro (Liang et al., 2021).
