background: in prostate cancer, mutated p53 alleles typically contain missense single-base substitution in codon 72 that resides within exons 5-8. stable p53 proteins in tumor cell nuclei have been associated with malignancy. a role of p53 is the regulation of drug transporters like abcc1 (mrp1) by an effect on promoter region.objectives: the objective of this study was to identify association ...
Primary open angle glaucoma (POAG) is the most common type of glaucoma. The p53 codon 72 Arg-Pro (CGC to CCC) polymorphism of exon 4 affects various biological properties; recently, it was reported that this polymorphism affects the ability to induce apoptosis in vitro. Various genotypes have been found to be significantly associated with POAG. We examined the distribution of this polymorphism ...
Previous reports have indicated that MDM2 T309G polymorphism might be a risk factor for various cancers. Increasing studies have been conducted on the association of MDM2 T309G polymorphism with hepatocellular carcinoma (HCC) risk. However, the results remain inconclusive. Thus, the present study aimed to address this controversy by meta-analysis. Relevant literature up to Oct 2014 was searched...
Oral lichen planus (OLP) is a chronic relapsing inflammatory disease. It involves T-lymphocyte aggression targeted to the basal layer of oral mucosa.p53 plays central role in prevention normal cells from development malignant phenotype. Somatic alterations p53 cause defects function. Wild type an important repairable damage cell due cellular stresses. Over-expression, as well polymorphic varian...
PURPOSE It is known that a common p53 polymorphism, encodingeither proline (Pro) or arginine (Arg) at residue 72, produces marked change in the structure of p53. Furthermore, the Arg72-containing allele is preferentially mutated and retained in various human tumors, suggesting that polymorphic residue within p53 modifies mutant behavior. We studied to determine whether Arg72 could be a risk fac...
introduction: endometriosis is a prevalent gynecological disorder among women which is diagnosed by the growth of endometrial tissue outside of uterus and is mainly accompanied by severe pelvic pain and infertility. p53 also known as cellular tumor antigen p53 inside codons 11, 72 and 248 are contained with single nucleotide changes in which tends to be nearly rampant.this will probably be incr...
BACKGROUND AND AIM p53 activity plays a role in muscle homeostasis and skeletal muscle differentiation; all pathways that lead to sarcopenia are related to p53 activities. We investigate the allelic frequency of the TP53 codon 72 in exon 4 polymorphism in the Italian female population and the association with appendicular skeletal muscle mass index in normal weight (NW), normal weight obese (NW...
BACKGROUND Many studies have reported that the p53 codon 72 polymorphism is associated with acute myeloid leukemia (AML) susceptibility; however, the conclusions are inconsistent. Therefore, we performed this meta-analysis to obtain a more precise result. MATERIAL AND METHODS We searched PubMed to identify relevant studies, and 6 published case-control studies were retrieved, including 924 AM...
Tumor suppressor p53 is a critical player in the fight against cancer as it controls the cell cycle check point, apoptotic pathways and genomic stability. It is known to be the most frequently mutated gene in a wide variety of human cancers. Single-nucleotide polymorphism of p53 at codon72 leading to substitution of proline (Pro) in place of arginine (Arg) has been identified as a risk factor f...
Although there is evidence suggesting genetic susceptibility for keloids, studies investigating the association between Arg72Pro polymorphism in the P53 gene and tendency to form keloids have given variable results. We made a meta-analysis of the effects of P53 Arg72Pro polymorphism on keloid risk in the Chinese population by conducting searches of the published literature in Pubmed, Embas...
