BACKGROUND The TP53 Arg72Pro polymorphism encodes two p53 variants with different biochemical properties. Here we investigated the impact of this polymorphism on the expression of key p53 target genes in a panel of human breast carcinomas, breast cancer risk, and age at onset. METHODOLOGY/PRINCIPAL FINDINGS The Arg72Pro polymorphism was genotyped in 270 breast cancer patients and 221 control ...

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...

Mutations in the gene TP53, which codifies the tumor suppressor protein p53, are found in about 50% of tumors. These mutations can occur not only at somatic level, but also in germline. Pediatric cancer patients, mostly with additional family history of malignancy, should be considered as potential TP53 germline mutation carriers. Germline TP53 mutations and polymorphisms have been widely studi...

BACKGROUND Colorectal cancer (CRC) is one of the leading causes of mortality and morbidity. The Kashmir valley, in Northern India, has been described as a high-risk area for colorectal cancer. AIM The aim was to make a preliminary attempt to study mutations in exons 5-8 (the DNA binding domain) of the tumour suppressor gene TP53 in 42 CRC patients from Kashmir. MATERIALS AND METHODS The stu...

The p53 tumor suppressor gene (TP53; OMIM: 191170) plays an important role in tumorigenesis in lung epithelial cells. TP53 encodes a sequence-specific DNA-binding protein that regulates transcription of several genes in response to DNA damage promoting cell cycle arrest, DNA repair or apoptosis. A mutation does not necessarily alter the protein function and since not all altered tumor protein p...

Background: The p53 tumor suppressor gene plays important roles in genomic stability. Several reports have noted racial differences in the prevalence of p53 genotypes at the codon 72 in patients with endometriosis.To study the association of endometriosis with p53 codon 72 polymorphism in the population of Isfahan. Materials and Methods: We undertook a case–control study to examine the possible...

background: the tumor suppressor gene tp53 (alias p53) located on chromosome 17 is involved in various cancers. case-control studies have shown that p53 codon 72 polymorphism modulates the prognosis and susceptibility to various malignancies. we undertook the present study to explore a possible association between mucinous and non-mucinous adenocarcinomas with different genotypes or alleles at ...

Breast cancer in families with germ line mutations in the TP53 gene has been described in the medical literature. Mutation screening for susceptibility genes should allow effective prophylactic and preventive measures. Using single-strand conformational polymorphism, we screened for mutations in exons 5, 6, 7 and 8 of gene TP53 in the peripheral blood of 8 young non-affected members (17 to 36 y...
