PURPOSE A common polymorphism of the tumor suppressor gene TP53 at codon 72 has been associated with human cancer susceptibility. The prognostic role of the polymorphism was assessed in 102 patients with advanced gastric adenocarcinoma. EXPERIMENTAL DESIGN We followed up 102 consecutive Caucasian patients with advanced gastric adenocarcinoma for >5 years and determined the status of the TP53 ...
This study was conducted in order to investigate the implications of the R72P polymorphism in the TP53 gene in breast cancer risk. The enlightenment of this matter might provide a piece of information about the potential implications of this polymorphism in patient risk. A meta-analysis was conducted considering a large sample size from studies with conflicting results on the R72P polymorphism ...
The amino acid substitution Arg72Pro in the TP53 protein has an impact on the biochemical and biological activity of this protein, and is associated with several types of cancers. However, the Arg72Pro polymorphism exhibits inconsistent contribution as a risk factor in various cancer types. Therefore, using PCR-RFLPs, we investigated the distribution of Arg72Pro genotypes and alleles in patient...

Monoallelic TP53 inactivation is associated with poor prognosis in chronic lymphocytic leukemia: results from a detailed genetic characterization with long-term follow-up. Blood. 2008;112(8): 3322-3329. 2. Malcikova J, Smardova J, Rocnova L, et al. Monoallelic and biallelic inactivation of TP53 gene in chronic lymphocytic leukemia: selection, impact on sur...
BACKGROUND TP53 mutations have been associated with resistance to anthracyclines but not to taxanes in breast cancer patients. The MDM2 promoter single nucleotide polymorphism (SNP) T309G increases MDM2 activity and may reduce wild-type p53 protein activity. Here, we explored the predictive and prognostic value of TP53 and CHEK2 mutation status together with MDM2 SNP309 genotype in stage III br...
Somatic mutations in TP53 are the most frequent events in human cancer and lead to inactivation of the gene, loss of tumour suppressor function, and in some cases generation of a dominant negative form of p53. Eleven exons make up the primary transcript of TP53, of which exons 2-11 encode the protein. Five conserved domains exist in exons 1, 4, 5, 7, and 8, which are considered essential for no...
Recent studies have suggested that genetic polymorphisms in the TP53 pathway influence tumour formation, progression and response to therapy. We analysed the three most common TP53 gene polymorphisms as potential genetic markers to predict the development and prognosis of breast cancer. The incidence of R72P, PIN3 Ins 16bp and PIN6 G13494A polymorphisms was determined in a cohort of 117 breast ...
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...
