Abstract:
Objective To investigate the expression of hMLH_1 in gastric cancer and its significance,Methods The expressions of hMLH_1 protein and mRNA were detected by immunohistochemistry and reverse transcription polymerase chain reaction(RT-PCR) in 68 cases of gastric cancer tissues,33 cases of para-cancer tissues and(35 cases) of normal gastric tissues.Apoptosis was assayed by terminal deoxytransferase mediated dUTP nicked labeling.Results The positive expression rates of hMLH_1 mRNA were 63.3%(43/68),100%(33/33) and 100%(35/35),and those of protein were 61.8%(42/68),93.9%(31/33),100%(35/35),respectively,in gastric cancer tissues,para-cancer tissues and normal gastric tissues.There was a correlation between the expression of hMLH_1 and clinical grade of gastric cancer(r=0.531,P
