ABSTRACT
OBJECTIVE: To evaluate the relatinship between the expression of P51, P73 and the oncogenesis and development of human gastric carcinoma. METHODS: The expression of P73 mRNA were detected both in 32 human gastric carcinoma tissues and adjacent normal gastric tissues by reverse transcriptase polymerase chain reaction (RT-PCR). RESULTS: Overexpressions of P73 mRNA were found in 17/32 gastric carcinoma tissues,in 2/32 adjacent normal gastric tissues.The positive expression rate of P73 mRNA in gastric carcinooma tissues was significantly higher than in adjacent normal gastric tissues( P<0.01). However, a significant correlation was found between the positive expression rate of P73 mRNA in gastric carcinoma tissues and the TNM staging(P<0.05). THe low expressions of P51A mRNA and P51B were found in all gastric carcinoma tissues and adjacent normal gastric tissues. The expression of P51A in gastric carcinoma tissues were much higher than adjacent normal gastric tissues (P<0.05). The expression of P51B is no significant correlation was observed between gastirc carcinoma tissues and adjacent normal gastric tissues. CONCLUSION: The results suggest that there is an overexpression odf P73 and P51A mRNA in gastric cancer tissues, and their expressions is relationship with oncogenesis and developnment of gastric carcinoma.
