Obsjective: To investigate the difference of expression of Cx26 mRNA, Cx32 mRNA and Cx43 mRNA between HCC tissues and liver tissues. To probe the regularity and significance of expression of Cx26, Cx32 and Cx43 in HCC. Method: HCC tissues and liver tissues were collected from 28 cases of pathological proved hepatocellular carcinoma. RT-PCR methods were then adopted to detect the expression of Cx26 mRNA, Cx32 mRNA and Cx43 mRNA in all tissues. Result: Cx26 mRNA and Cx32 mRNA were found to expressi...
