UNLABELLED TP53 is a major gene involved in the determination of proliferation or growth arrest at the cellular level. The polymorphism of p53 at codon 72 has been widely studied; this variation has been associated with cancer susceptibility and disease outcome. The specific aim of this study was to investigate whether the p53 codon 72 polymorphism is associated with individual susceptibility t...
BACKGROUND Stomach cancer (SC) and colorectal cancer (CRC) present with high rates of incidence and mortality in the worldwide population. These 2 tumors are characterized by great genetic heterogeneity. Up to now, there have been no molecular studies that analyze the mutations in the APC, KRAS, and TP53 genes in the Colombian/Latin American population. OBJECTIVES To analyze mutations in the ...
The TP53 5'-untranslated region flanking the gene WRAP53 (also known as WDR79 and TCAB1) has been hypothesized to be associated with cancer risk due to its critical function in regulating p53 levels. In this review, we analyzed the association between the WRAP53 gene rs2287499 C>G polymorphism and risk of cancer using five case-control studies, comprising seven datasets. All analyses were perfo...
Somatic mutations affecting the mitochondrial DNA (mtDNA) have been frequently observed in human cancers and proposed as important oncological biomarkers. However, the clinical significance of mtDNA mutations in cancer remains unclear. This study was therefore performed to explore the possible clinical use in assessing oral squamous cell carcinoma (OSCC) of pathogenic mtDNA mutations. The entir...
Purpose: The germ-line polymorphisms TP53 Arg72Pro and MDM2 SNP309 T>G are risk factors for tumor development and affect response to chemotherapy and survival in several cancers, but their prognostic and predictive value in patients with high-grade osteosarcomas is not yet defined. The purpose of this study was to investigate the effect of the TP53 Arg72Pro and the MDM2 SNP309 on the risk of os...
In the United States and the San Francisco Bay Area, whites are nearly twice as likely as non-whites to develop brain cancer. To test whether prevalence and types of alterations in the p53 pathway in brain tumor development may explain some of this difference in risk, we have analyzed the p53 status of astrocytic gliomas from a population-based sample of cases within our San Francisco Bay Area ...
The prevalence and significance of genetic abnormalities in older patients with acute myeloid leukemia (AML) are unknown. Polymerase chain reactions and single-stranded conformational polymorphism analyses were used to examine 140 elderly AML patients enrolled in the Southwest Oncology Group study 9031 for FLT3, RAS, and TP53 mutations, which were found in 34%, 19%, and 9% of patients, respecti...
سابقه و هدف: سرطان پستان، شایعترین سرطان در زنان است که ژن سرکوبگر توموری TP53 نیز از فراوانترین ژنهای تغییر یافته در سرطانهای انسانی می باشد. ارزیابی دقیق جهش های ژن TP53 در مبتلایان سرطان می تواند در تشخیص ، پیش آگهی یا درمان اهمیت داشته باشد. این مطالعه به منظور شناسایی جهشهای این ژن در مبتلایان سرطان پستان انجام شد. مواد و روش ها: در این مطالعه توصیفی، تعداد 102 نمونه توموری از زنان آذ...
BACKGROUND TP53 defects, i.e., 17p13 deletion and/or nucleotide mutations, associate with short survival and chemorefractoriness in chronic lymphocytic leukemia (CLL). In this context, since direct sequencing of the TP53 gene does not evaluate TP53 functionality, a functional assessment of TP53 pathway may be of interest to identify high risk CLL. By taking advantage of a training cohort of 100...
introduction: endometriosis is a prevalent gynecological disorder among women which is diagnosed by the growth of endometrial tissue outside of uterus and is mainly accompanied by severe pelvic pain and infertility. p53 also known as cellular tumor antigen p53 inside codons 11, 72 and 248 are contained with single nucleotide changes in which tends to be nearly rampant.this will probably be incr...
