Abstract:
Objective To study the clinicopathological significance of the expression of glutameta decarboxylase 65(GDA65) and protein kinase C(PKC) in the central cancer tissues, cancer edge tissues, paracancerous liver tissue and non-cancer liver tissues. Methods The expression of GDA65 and PKC were detected by immunohistochemical method in 10% neutral formalin- fixed and routinely paraffin-embedded sections in 37 hepatic cancer specimen. Results The positive rate and the score of GDA65 and PKC in the cancer tissues were significantly higher than that in the paracancer tissues or non-cancer liver tissues, but the PKC expression was no difference between the central cancer tissues and the cancer edge tissues . The expression of GDA 65 was related to the pathological types, differentiated degrees, liver cirrhosis or metastasis of hepatocarcinomas. No correlation was found between the expression of PKC and the clinicopathological features of hepatocarcinomas. Conclusions The expression of GDA65 and PKC might be closely related to the carcinogenesis of hepatocarcinoma, they might be important biological markers of hepatocarcinoma.
