Title: EXPRESSION OF INSULIN-LIKE GROWTH FACTOR II(IGF-II)IN HUMAN HEPATOCELLULAR CARCINOMA AND LIVER CIRRHOSIS:ITS RELATIONSHIP WITH HEPATITIS B VIRUS X PROTEIN EXPRESSION
Abstract: Sixty cases of hepatocellular carcinoma (HCC) and47 cases of liver cirrhosis (LC) were examined withimmunocytochemistry method using antibodies againstIGF-II and HBxAg on formalin-fixed, paraffin-embeddedtissue sections. 32 HCC and 37 LC were found to bepositive to HBxAg, in which the positive rates of IGF-IIwere 100% (32/32) and 94.6% (35/37) respectively. 28HCC and 10 LC were found to be HBxAg negative, IGF-IIwas positive in 23 HCC (83.1%) and 6 LC:(60%) Thepositive expression rates of IGF-II in HBxAg positivetissues were significanfly higher than those in HBxAgnegative tissues (P<0.05). There were three types ofdistribution of IGF-II expression in HCC and LC (1)perinucleus: (2) diffuse in cytoplasm; (3) inside nucleus.IGF-II was highly expressed in most of hyperplastic andneoplastic nodules hepatocytes and some of regenerationnodules. Small polygonal liver cells (SPLCs) were foundin the liver tissues surrounding the tumor and cirrhosisand they were positive to both IGF-II and HBxAg. Thepositive rates
