Upon pathological examination, a
coffee preparation treatment significantly reduced liver damage and symptoms of liver fibrosis. The mRNA expression of collagen I, collagen III, bcl-2, vascular endothelial growth factor (VEGF) and transforming growth factor-beta1 (TGF-beta1) were markedly increased by CCl(4) treatment but suppressed by a coffee preparation treatment. Whereas compared with the CCl(4) group, the mRNA expression of Bax was increased in the coffee preparation group.
