Hepatic fibrosis refers to the excessive deposition of collagen fibers and subsequently evolves liver cirrhosis to HCC. Currently, there is not successful therapeutic approach to liver fibrosis in addition to liver transplantation for patients with decompensate liver cirrhosis. Therefore, it is important to identify cellular and molecular mechanism that promote liver damage or provide hepatoprotection for development of therapeutic approaches. The GH-IGF-IGFBP axis consists of growth hormone (GH), two growth factors (IGF-I and IGF-II), theirreceptors (IGF-IR and IGF-IIR) and a group of binding proteins  (IGFBP1-7). In the recent years, accumulating evidences have demonstrated that the elements of this axis play the important roles in the pathogenesis of liver fibrosis. In this review, we first summarize genomic and pathological information of the IGF-IGFBP axis and further review the roles of each element of this axis in the pathogenesis of liver fibrosis.
