Expression of VEGF-A, Otx Homeobox and p53 Family Genes in Proliferative Vitreoretinopathy
INTRODUCTION Proliferative vitreoretinopathy (PVR) is a severe inflammatory complication of retinal detachment. Pathological epiretinal membranes grow on the retina surface leading to contraction, and surgery fails in 5% to 10% of the cases. We evaluated the expression of VEGF-A, Otx1, Otx2, Otx3, and p53 family members from PVR specimens to correlate their role in inducing or preventing the pa...
متن کاملThe origins and evolution of the p53 family of genes.
A common ancestor to the three p53 family members of human genes p53, p63, and p73 is first detected in the evolution of modern-day sea anemones, in which both structurally and functionally it acts to protect the germ line from genomic instabilities in response to stresses. This p63/p73 common ancestor gene is found in almost all invertebrates and first duplicates to produce a p53 gene and a p6...
متن کاملComparison of the Expression Level of P53 and Proliferating Cell Nuclear Antigen (PCNA) Genes in the Inflamed and Non-Inflamed Dentigerous Cysts
Background & Aims: The role of P53 and proliferating cell nuclear antigen (PCNA) genes in inflamed and non-inflamed odontogenic cysts is related to cell proliferation but it is unclear. The aim of this study was immunohistochemical evaluation of P53 and PCNA expression in inflamed and non-inflamed dentigerous cysts Methods: In the present study, 23 dentigerous cysts (12 inflamed and 11 non-infl...
متن کاملBCL2 Family Related Genes Expression and Chemotherapy Response in Diffuse Large B-Cell Lymphoma
Background and Objective: Approximately half of patients with diffuse large B-cell lymphoma are cured with current chemotherapy regimens. The purpose of this study was to evaluate Bax and Bcl2 expression and their relationship with the response to chemotherapy. Materials and Methods This study was a prospective analysis on 44 patients with diffuse large B-cell lymphoma. Their specimens we...
متن کاملp53 expression and K-ras mutation in colorectal adenomas.
The frequency of p53 overexpression and K-ras codon 12 mutation was investigated in a series of colorectal adenomas. p53 was detected by immunohistochemistry in only 5% of tumours, whereas K-ras mutation was found in eight of 30 adenomas examined. In vitro, mutant p53 and ras genes cooperate to transform primary rat cells into a tumourigenic cell line. The presence of both p53 overexpression an...
