Hepatic expression of HIF-1α (A,B), EPO (C), VEGF (D) and iNOS (E, F) transcripts in rats with BDL and TAA-induced fibrosis. Transcripts were quantified by TaqMan PCR, normalized to GAPDH and expressed as x-fold change (means±SD). PF – peak of fibrosis; *p<0.05 vs the corresponding fibrosis control.
