BACKGROUND Non-melanoma skin cancers are one of the most common human malignancies accounting for 2-3% of tumors in the US and represent a significant health burden. Epidemiology studies have implicated Tp53 mutations triggered by UV exposure, and human papilloma virus (HPV) infection to be significant causes of non-melanoma skin cancer. However, the relationship between Tp53 and cutaneous HPV ...
The aim of the study was to determine an association of TP53 codon 72 (Arg72Pro, G>C transversion, rs1042522) and MDM2 SNP309 (T>G change, rs2279744) polymorphisms in endometrial cancer (EC) of postmenopausal women, regarding grading and staging of EC. In the study, endometrial samples from 202 postmenopausal female patients (the study group, n = 152, was women with EC; the control group, n = 5...
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...
The p53 tumor suppressor gene plays two important roles in genomic stability: blocking cell proliferation after DNA damage until it has been repaired, and starting apoptosis if the damage is too critical. Codon 72 exon4 polymorphism (Arg72Pro) of the P53 gene has been implicated in cancer risk. Various studies have been done to investigate the status of p53 at codon 72 for arginine (Arg) and pr...
Breast cancer is the most common female malignancy worldwide. Despite the high incidence of sporadic cases, the rate of familial breast cancer is low. The tumor suppressor gene TP53 (alias p53), located on chromosome 17, has been involved in various malignancies. Mutations in codon 72 of TP53 have been studied in breast cancer and most solid tumors. For study of polymorphisms and allele frequen...
INTRODUCTION The aim of this study was to detect TP53 Arg72Pro polymorphism in postmenopausal patients with endometrial cancer (EC), to evaluate the risk of EC connected with it, as well to check for possible relationships with staging, grading and some risk factors of this neoplasm. MATERIAL AND METHODS Endometrial samples from 152 women with EC and from 50 cancer-free ones were taken for ge...
Human TP53 gene is characterised by a polymorphism at codon 72 leading to an Arginine-to-Proline (R/P) substitution. The two resulting p53 isoforms have a different subcellular localisation after stress (more nuclear or more mitochondrial for the P or R isoform, respectively). p53P72 variant is more efficient than p53R72 in inducing the expression of genes involved in nuclear DNA repair. Since ...
