摘      要：AIM: To investigate gene expression profiles of intergringenes in hepatocellular carcinoma (HCC) through theusage of Atlas Human Cancer Array membranes, semi-quantitative reverse transcription polymerase chainreaction (RT-PCR) and Northern ***: Hybridization of cDNA array membrane wasperformed with α 32P-labeled cDNA probes synthesizedfrom RNA isolated from hepatocellular carcinoma andadjacent non-cirrhotic liver. AtlasImage, which is asoftware specific to array, was used to analyze theresult. RT-PCR of 24 pairs specimen and Northern blotof 4 pairs specimen were used to confirm the expressionpattern of some intergrin genes identified by Atlasarrays ***: Among 588 genes spotted in membrane, 17genes were related to intergrin. Four genes were up-regulated, such as intergrin alpha8, beta1, beta7 andbeta8 in HCC. Whereas there were no genes down-regulated in HCC. RT-PCR and Northern blot analysisof intergrin beta1 gene gave results consistent withcDNA array ***: Investigation of these intergrin genesshould help to disclose the molecular mechanism of thecell adhesion, invasive and metastasis of HCC. A fewgenes are reported to have changed in HCC for the firsttime. The quick and high-throughout method of profilinggene expression by cDNA array provides us overviewof key factors that may involved in HCC, and may findthe clue of the study of HCC metastasis and moleculartargets of anti-metastasis therapy. The preciserelationship between the altered genes and HCC is amatter of further investigation.
