Immunohistochemical Expression of p53 and bcl2 in Colorectal Adenomas and Carcinomas Using Automated Cellular Imaging System
Background & Objective: The current approaches to reduce the risk of colorectal carcinoma are through the detection and removal of the precursor lesion” adenomatous polyps”. The study was conducted to evaluate the immunohistochemical expression of p53 and bcl2 in colorectal adenomas and carcinomas. Patients and Methods: A total of 86 cases, 33 colorectal adenomas, 33 colorect...
متن کاملP53 and Ki67 protein expression in ocular squamous cell carcinomas of dairy cattle
Role of the protein overexpression is very important in the pathogenesis, diagnosis and prognosis of neoplasia. Cases of overexpression of p53 and Ki67 proteins were investigated in 19 ocular squamous cell carcinomas (OSCC) in dairy cows. Microscopically, insix cases the tumors were carcinoma in situ (noninvasive carcinoma, G0), and in the remaining 13 cases the tumors were invasive carcinoma. ...
متن کاملA preliminary study of microsatellite instability analysis in different genotypes of p53 codon 72 in breast invasive ductal carcinomas
Abstract Background: The polymorphic variants at codon 72 of the p53 gene, encoding either proline or arginine at residue 72, produce marked change in the structure of p53. From the evidence that the DNAmismatch repair system and p53 interact to maintain genomic integrity, we hypothesized that the codon 72 variation may influence the prevalence of microsatellite instability a featur...
متن کاملLoss of heterozygosity of p53 gene and p53 protein expression in human colorectal carcinomas.
The p53 gene is a tumor suppressor gene located on chromosome 17p. Deletions of this chromosome and point mutations of p53 have been implicated in the development of colonic neoplasms. We have analyzed the loss of heterozygosity of the human p53 tumor suppressor gene in 40 cases of colorectal carcinoma using two restriction fragment length polymorphisms detected by BglII and AccII restriction e...
