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 reaction-mediated single-strand conformation polymorphism (PCR-SSCP) 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...

PURPOSE to evaluate the frequency of TP53 codon 72 polymorphism in infertile women with endometriosis, women with idiopathic infertility, controls and its relation to the disease. METHODS a case-control study that included 198 infertile women with endometriosis, 70 women with idiopathic infertility and 169 fertile women without endometriosis as control. Detection of TP53 codon 72 gene polymor...

BACKGROUND TP53 mutations are the most common genetic alterations in human cancers. There are also several polymorphisms in both exons and introns of TP53 that may influence its anti-tumor functions and increase the risk of cancer development. Associations of the TP53 intron 6 G13964C polymorphism with increased risk of development of several cancers have been investigated in numerous studies, ...

TP53 accumulation in human primary breast carcinomas was studied by a quantitative luminometric immunoassay (LIA), and TP53 gene alterations, exons 5-8, were examined by single-strand conformation polymorphism (SSCP) analysis. In 48 of 142 breast tumor samples, a TP53 gene alteration was identified. In tumor samples without a TP53 gene alteration, the median cytosolic TP53 protein level, as det...

Although it is known that chronic hepatitis C virus (HCV) infection may contribute to tumor initiation and development, the molecular processes causing hepatocellular carcinoma (HCC) remain unclear. Microindels are unique, infrequent mutations that result in inserted and deleted sequences at the same nucleotide position, and are important contributors to cancer. To date, microindels in the p53 ...

The present study analyzed the association of tumor protein p53 (TP53) Pro72Arg polymorphism with esophageal squamous cell carcinoma (ESCC) in the Mongolian population of Tongliao (Inner Mongolia, China). Restriction fragment length polymorphism-polymerase chain reaction was used to detect the genotype distribution of TP53 Pro72Arg polymorphism in 100 patients with ESCC and 50 healthy controls ...

The association between TP53 gene polymorphisms and breast cancer (BC) in Brazilian women is a controversial topic. In this cross-sectional study, we evaluated the association between clinical pathological variables and three polymorphisms (TP53*11, TP53*72, and TP53*248) in BC patients and controls. Genomic DNA was extracted from the blood cells of 393 participants; the cancer-free control sub...

Breast cancer is the most common neoplasia as well as the main cause of cancer-related death among women, experiencing a 0.5% increase in incidence per year. The disease results from a series of mutations in the DNA development and repair genes. Approximately 50% of human carcinomas present mutations in the TP53 gene. Polymorphisms of TP53 include codon 72 containing either arginine (CGC) or pr...

The pattern of somatic mutations in TP53 is distinct for particular cancers and carcinogenic exposures, providing clues to disease etiology, e.g. G:C-->T:A mutations in TP53 are more frequently observed in smoking-associated lung cancers. In order to investigate possible causes and mechanisms of lung cancer susceptibility differences, the TP53 gene was sequenced in a case-only study of lung can...

BACKGROUND Although many epidemiologic studies investigated the TP53 codon 72 polymorphism and its association with cervical cancer (CC), definite conclusions cannot be drawn. AIM OF THE STUDY To evaluate the association between TP53 codon 72 polymorphism and risk of cervical cancer in the Chinese population. METHODS A computerized literature search was carried out in PubMed, Springer Link,...
