immunohistochemical expression of p53 and bcl-2 proteins in advanced esophageal cancer patients
the current challenges in the management of esophageal cancer are to obtain a better understanding of underlying molecular alterations to provide new treatment options. we studied the p53 and bcl-2 protein expression in esophageal carcinomas to correlate molecular alterations with clinicopathological findings. tissue samples of 37 patients with advanced esophageal carcinoma were analyzed by imm...
متن کاملImmunohistochemical expression of PCNA, p53, bax and bcl-2 in oral lichen planus and epithelial dysplasia.
The potential for malignant transformation of oral lichen planus is still controversial. The expression of proteins related to cell proliferation and apoptosis in oral lichen planus and epithelial dysplasia was analyzed to evaluate the true potential for malignant transformation of this disease. Twenty-four cases of each lesion were subjected to the streptoavidin-biotin technique for identifyin...
متن کاملO-39: Evaluation the Expression of Bax,Bcl-2, p53 & Survivin After Treatment ofCryptorchidism in Mouse
Background: Experimental cryptorchidism is a common model for examining the expression and function of heat-induced spermatogenesis related genes in testis. In this study the expression of genes & proteins thatinvolved in programmed cell death after treatment of cryptorchidism was examined. Materials and Methods: To induce bilateral cryptorchid model immature mice were anesthetized and a small ...
متن کاملExpression of p53, p21/waf, bcl-2, bax, Rb and Ki67 proteins in colorectal adenocarcinomas.
This study investigated the combined immunoexpression of p53, p21, bcl-2, bax, Rb and Ki67 proteins in colorectal adenocarcinomas and correlated expression patterns with tumour stage and grade. Paraffin sections from 98 cases of colorectal adenocarcinomas were stained by immunohistochemistry for p53, p21, bcl-2, bax, Rb and MIB-1 (Ki67) proteins. In addition, 12 cases of colorectal adenomas and...
متن کاملestimation of malignant transformation rate in cases of oral epithelial dysplasia and lichen planus using immunohistochemical expression of ki-67, p53, bcl-2, and bax markers
background: materials and methods: this was a cross-sectional study carried out among 70 samples, including 10 samples from normal healthy mucosa categorized into group 1, group 2 (30 olp), and group 3 (30 oed) samples. five sections (4 μm thick) were obtained and stained with monoclonal antibodies such as ki-67, p53, bcl-2, and bax and analyzed for number of positive cells and also for inten...
