Core Tip

Core Tip: Abnormal expression of insulin-like growth factor-1 receptor (IGF-1R) was associated with hepatocellular carcinoma (HCC). IGF-1R level was significantly higher in HCC more than that in their noncancerous tissues. Circulating IGF-1R continued to increase from benign liver disease to HCC. Down-regulating expression of IGF-1R with a specific sgRNA was markedly affected on biological behaviors of HCC cells, including inhibiting cell proliferation, decreasing cell migration or invasion potential, increasing cell apoptosis and enhancing cell susceptibility to anti-tumor drugs and indicated that oncogenic IGF-1R should be a promising targeted-molecule for HCC therapy.
