Baicalein inhibits nuclear factor-κB and apoptosis via c-FLIP and MAPK in D-GalN/LPS induced acute liver failure in murine models.
Chem Biol Interact 2010; 188(3):526-34CB

Abstract

The hepatoprotective effects and molecular mechanisms of baicalein on acute liver failure induced by d-galactosamine (d-GalN)/lipopolysaccharides (LPS) were investigated in vivo. Mice were administered with different doses of baicalein (50, 100 or 150mg/kg, p.o.) 1h before injection of d-GalN (700mg/kg)/LPS (10μg/kg) and then sacrificed 6h after treatment with d-GalN/LPS. Pretreatment with baicalein prevented d-GalN/LPS-induced liver damage by preventing associated increases of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) and by reducing serum tumor necrosis factor α (TNF-α), nitric oxide (NO) or inducible nitric oxide synthase (iNOS) expressions. The molecular mechanisms involved in baicalein-induced inhibition of d-GalN/LPS-caused apoptosis were associated with the protection of mitochondria, increasing the Bcl-2/Bax ratio, blocking the release of cytochrome c, and suppressing the phosphorylation of IκBα, ERK and JNK. Moreover, baicalein activated c-FLIP(L), XIAP and cIAP2 proteins, potentially blocking the recruitment of NF-κB signaling molecules. The results support the investigation of baicalein as a therapeutic candidate for acute liver apoptosis or injury and indicate that baicalein might inhibit liver apoptosis by mediating one or more of these pathways.
