The tumor suppressor gene p53 and its downstream effector p21 are thought to play major roles in the development of human malignancy. Polymorphic variants of p53 at codon 72, and p21 at codon 31, have been found to be associated with cancer susceptibility, but few studies have investigated their effect on prostate cancer risk. In this case-control study, we investigated the association of p53 c...
OBJECTIVE Individual studies of the associations between P53 codon 72 polymorphism (rs1042522) and bladder cancer susceptibility have shown inconclusive results. To derive a more precise estimation of the relationship, we performed this systemic review and meta-analysis based on 15 publications. METHODS We used odds ratios (ORs) with 95% confidence intervals (CIs) to assess the strength of th...
BACKGROUND The polymorphism of TP53 codon 72, a transversion of G to C (Arg to Pro), has been demonstrated to be associated with the risk for lung cancer. However, individual studies conducted in Chinese have provided conflicting and inconclusive findings. Thus, we performed a meta-analysis by pooling all currently available case-control studies to estimate the effect of TP53 codon 72 Arg/Pro p...
PURPOSE Glaucoma is a complex neurodegenerative disorder of the eye. Primary Open Angle Glaucoma (POAG) is the most common type, accounting for over half of the total cases. Recently, a significant difference in the distribution of the codon 72 polymorphism of the tumor suppressor gene p53 between control subjects and POAG patients of Chinese origin (p=0.00782) was demonstrated. The proline res...
Meta-analysis demonstrates no association between p53 codon 72 polymorphism and prostate cancer risk
To evaluate the association of the TP53 codon 72 (rs 1042522) alone or in combination with HDM2 SNP309 (rs 2279744) polymorphisms with human infertility and IVF outcome, we collected 1450 infertility women undergoing their first controlled ovarian stimulation for IVF treatment and 250 fertile controls in the case-control study. Frequencies, distribution, interaction of genes, and correlation wi...
In addition to a common polymorphism at codon 72, the p53 tumor suppressor gene also contains a rare single nucleotide polymorphism at amino acid 47. Wild type p53 encodes proline at this residue, but in <5% of African Americans, this amino acid is serine. Notably, phosphorylation of the adjacent serine 46 by the proline-directed kinase p38 MAPK is known to greatly enhance the ability of p53 to...
Mutations of the p53 gene represent the most common genetic alterations in human cancer. Several reports have focused on p53 polymorphisms as risk factors in lung cancer, in particular at codon 72 of exon 4, encoding either an arginine (Arg72R) or a proline (Pro72P) amino acid. Polymorphisms at codon 72 of the p53 gene were determined using a PCR-RFLP-based method. We analysed the relationship ...
