摘要: AIM: To investigate cytpchrome P4502E1 (CYP2E1) gene expression in occurrence and progression of hepatocellular carcinoma (HCC). METHODS: The human liver arrayed library was spotted onto the nylon membranes to make cDNA array. Hybridization array performed with labeled probes synthesized from RNA isolated HCC adjacent tissues. Sprague-Dawley rats were administrated diethylnitrosamine (DENA) induce HCC. CYP2E1 detected by method RT-PCR Northern blot analysis. RESULTS: found hybridization express differently between only expressed liver, but did not tissues lowly cirrhotic In cirrhosis HCC, level gradually decreased hardly until late stage HCC. CONCLUSION: Using arrays is an effective find differential genes. a unique expressing descended along initiation which noteworthy further investigations its significance development
