ABSTRACT
<p><b>OBJECTIVE</b>To investigate the frequency of cyclin A overexpression in hepatocellular carcinoma (HCC) and its relationship with clinical significance and HBx gene integration.</p><p><b>METHODS</b>PCR, RT-PCR and Western blot were used to detect the gene, mRNA and protein level of cyclin A in the tumor and nontumorous tissue. PCR and Southern blot were used to detect the integration of HBx gene in HCC.</p><p><b>RESULTS</b>Amplification of cyclin A gene was found in 1 of 35 patients; overexpression of cyclin A mRNA and protein was found in 16 of 35, 21 of 35 patients, respectively. Overexpression of cyclin A protein was correlated with patient's age, tumor size and HBx integration.</p><p><b>CONCLUSION</b>Overexpression of cyclin A occurs in the early stage of HCC carcinogenesis. It may be one of the important approaches by which HBV affects the normal cell cycle of hepatocyte.</p>
