Abstract:
Background and purpose:To study the expression of PTEN and P53 and analyse their roles in HGC oncogenesis,and to discover a good marker for diagnosis and prognosis of HGC.Methods:The expression of PTEN mRNA,PTEN protein and P53 protein were detected by in situ hybridization(DNA-RNA) and immunohistochemistry(SP method) in 64 cases of HGC.We took 22 cases of gallbladder adenoma and 10 cases of chronic cholecystitis as controls.Results:① The positive expression rates of PTEN mRNA and protein in HGC(56.3%,59.4%) were significantly lower than that in gallbladder adenoma(81.8%,90.8%) and chronic cholecystitis(100%,100%)(P
