Abstract	Abnormal expression of insulin-like growth factor I receptor (IGF-IR) is associated with hepatocellular carcinoma (HCC) progression with largely unknown mechanisms. In this study, IGF-IR expression among different HCC cell lines and silencing its gene transcription on effects of HCC were investigated by short hairpin RNA (shRNA). Specific shRNA was successfully transfected into Bel-7404 or PLC/PRF/5 cells with 90 or 71 % efficiency. The inhibiting rate of IGF-IR at mRNA level were 54.9 % in Bel-7404 or 59.6 % in PLC/PRF/5 cells in accordance with its protein suppression, with the cell cycles at the G$_{1}$ phase arrest and decreasing cyclinD1 via promoting apoptosis in vitro. With the xenograft models of PLC/PRF/5 cells inserted specific shRNA in vivo, the tumor-forming time (14.0 ± 1.1 days) or tumor volume (143 ± 24 mm$^{3}$) in the shRNA group was significantly lengthened or smaller than those in the control group (7.2 ± 0.8 days or 372 ± 46 mm$^{3}$, P < 0.001) or in the neg-shRNA group (7.5 ± 1.0 days or 350 ± 50 mm$^{3}$, P < 0.001). Silencing the IGF-IR gene transcription inhibited cell proliferation or xenograft tumor growth of HCC, suggesting that IGF-IR might be a novel potential target for HCC gene therapy.
