Study the activity of P53 & Bcl-2 genes in the biopsies of inflamed colon from patients of ulcerative colitis

Abstract

The study has been done on 36 samples of biopsies which drawn from patients suffered from ulcerative colitis, the samples were taken from female & male of different ages. The goal was to observe the gene expression of the suppresser tumor gene P53, & the suppresser apoptosis gene Bcl-2, by using in situ hybridization technique. The results showed that there were relationships between both genes (P53 & Bcl-2) in patients suffered from ulcerative colitis compared with healthy individuals. The suppresser gene P53 gave 63% in the high grade(3) , 29 % in the intermediate stage (2) & 8% in the low grade (1) .While for the suppresser apoptosis gene Bcl-2 , the results showed increasing in the activity of this gene , which gave 66% in the high grade(3) , 27% in the intermediate stage (2) , & 7% in the low grade (1) . These results indicate accumulated mutations in the gene P53 & increase in the activity of gene Bcl-2 in inflamed colonic tissue of chronic ulcerative colitis. This gave an indication of early detection for diagnostic, therapeutic and monitoring purposes.
