Raf kinase inhibitory protein (RKIP), besides regulating important intracellular signaling cascades, was described to be associated with progression, metastasis and prognosis in several human neoplasms. But its role in hepatic fibrogenesis remains unclear. In the present study, we found that the absence of RKIP expression significantly enhanced the proliferation of HSC-T6 cells. Reduced RKIP expression promoted the activation of HSCs and the accumulation of collagen, as evidenced by the increases in the levels of collagen I and α-smooth muscle actin. Moreover, down-regulating RKIP expression led to severe histopathological changes and collagen accumulation in hepatic tissues of rats with liver fibrosis. Furthermore, the absence of RKIP promoted the activation of ERK/MAPK pathway in vitro and in vivo. Our findings clearly demonstrate an inverse correlation between RKIP level and the degree of the liver injury and fibrosis. Loss of RKIP may be associated with malignant progression in hepatic fibrosis.
