Background: Prostate cancer is one of the most commonly diagnosed cancers in males. Tumor suppressor gene p53 plays an important role in causing cell cycle arrest and allowing apoptosis to proceed. Objective: To investigate the expression of p53 protein and its relation to apoptosis and prostate cancer traditional prognostic indicators. Methods: In this study expression of p53 was examined in p...

p53 and PCNA expression in keratocystic odontogenic tumors compared with selected odontogenic cysts Summary: The aim of this study was to evaluate p53 and PCNA expression in different odontogenic lesions regarding their different clinical behaviors. Slices prepared from 94 paraffin-embedded tissue blocks (25 radicular cysts (RC), 23 dentigerous cysts (DC), 23 keratocystic odontogenic tumors (KC...
cyclin e, her-2 and p53, are considered as major prognostic markers in breast cancer. as they are related in patho-clinical level, we aimed to check if they have any direct interaction on expression of each other. to study the effect of cyclin e on her-2 expression, cell lines stably overexpressing cyclin e or its low molecular weight (lmw) isoforms were generated. to understand the results of ...
Background and Objective: Breast cancer is the most commonly diagnosed cancer in women worldwide, which alone accounts for 30% of all new cancer cases in women. The development of cancer is a multistep process. The complex series of cellular and molecular changes participating in cancer development are mediated by a diversity of stimuli such as Oxidative stress that is known to cause DNA damag...
background there is a potential risk for malignancy in patients with diabetes mellitus. theoretically, a noninvasive method for detection of precancerous changes can be conducted on oral exfoliated cell smears. objectives in this study, the immunocytochemistry of p53 in exfoliated oral mucosal cells in patients with type 2 diabetes was investigated. patients and methods oral mucosal smears were...
Introduction & Objective: Hodgkin lymphoma accounts for about 1% of all cancers. Cyclooxygenase 2 (COX2) is a cytoplasmic enzyme. Oncogene, and growth factor induce over expression of COX2. COX2 is apoptotic inhibitor. Mutation of the p53 tumor suppressor gene represents the most common genetic alternation in human tumors. This study aimed to evaluate the expression of COX2 and p53 in subtype...
the p53 protein function is essential for the maintenance of the nontumorigenic cell phenotype. pancreatic tumor cells show a very high frequency of p53 mutation. to determine if restoration of wild type p53 function can be used to eliminate the tumorigenic phenotype in these cells, pancreatic tumor cell lines, panc-1 and htb80, differing in p53 status were stably transfected with exogenous wil...
Background: Widespread and growing sources of electromagnetic radiation raised concerns attributed to the potential adverse health risk of radiofrequency fields. Given the functional importance of the hippocampus, this study aimed to investigate the effects of electromagnetic waves radiated by mobile jammer on hippocampal expression of p21 and p53 genes as regulators of cellular apoptosis...
