Background TP53 R72P polymorphism has been proposed as a risk factor for breast cancer and is more likely to differ among different ethnic populations. We carried out the study to determine the role of R72P polymorphism in breast cancer patients of Kashmir, an ethnic population by PCR-RFLP. Methods To evaluate the role of this polymorphism in our ethnic Kashmiri population, we devised our stu...

We examined TP53 mutation in 57 patients with myelodysplastic syndrome (MDS) at either the MDS phase or at the terminal leukemic phase using polymerase chain reactionmediated single-strand conformation polymorphism (PCRSSCP) analysis. TP53 mutations within exons 5 through 8 were found in seven patients. All these mutations were detected at the presentation of MDS whether these patients showed l...

PURPOSE The tumor suppressor p53 is known to be inactivated frequently in various cancers. In addition, germline polymorphisms in TP53 are known to affect protein function and influence risk of developing different types of cancers. In this study, we analyzed the association of TP53 Pro72Arg polymorphism with squamous cell carcinoma of oral tongue (SCCOT) and esophagus (ESCC) in India. METHOD...

PURPOSE To determine the frequency and association of polymorphisms in the TP53 and RB1 genes with clinical characteristics in a group of children with retinoblastoma (RB) in northern Mexico. METHODS A prospective, longitudinal, and analytical study of 11 patients diagnosed with RB was conducted. Endpoint PCR and high-resolution real-time PCR were performed. Chi-square and Student t tests wer...

background: tumour suppressor genes such as tp53, brca1 and rad51 are involved in dna repair and their malfunctions result in genomic instability and cancer. wild type (wt) tp53 binds to brca1and rad51 in vivo and in vitro. however, mutated tp53 in tumours can interfere with wt tp53 function. we studied how mutation of tp53 in mda-mb-468 cell line could affect its binding capacity and interfere...

BACKGROUND TP53 gene is one of the most important tumor suppressor genes. We undertook this meta-analysis to explore the association between TP53 Arg72Pro polymorphism and the risk of skin cancer mainly in Caucasians. METHODS We searched PubMed for case-control studies published up to March 2013. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of associa...

The TP53 tumor suppressor gene plays an important role in cell cycle regulation; polymorphisms of this gene have been associated with endometriosis. We examined the role of TP53 codon 72 polymorphism by comparing genotypes of 235 healthy Mexican women (controls with surgically excluded endometriosis) with the genotypes of 151 Mexican women with endometriosis. The observed genotype frequenc...

The genotype of the fibroblast growth factor receptor 4 (FGFR4) gene and TP53 mutation have been reported as prognostic factors for cancers of the head and neck, bladder, breast and colon. To determine whether they are applicable for oral squamous cell carcinoma (OSCC), we investigated these two genes in OSCC samples from 150 patients who had undergone radical surgery and in 100 cancer-free ind...

Several previous studies evaluated the association between the Arg72Pro (rs1042522) polymorphism in the TP53 tumor suppressor gene and colorectal cancer (CRC). However, the results are conflicting. This meta-analysis aimed to shed new light on the precise association between TP53 variants and CRC. We analyzed 32 published case-control studies involving 8,586 cases and 10,275 controls using crud...
