Single-strand conformation polymorphism analysis to detect p53 mutations: characterization and development of controls.

تعیین جهش در اگزون 8 ژن p53 در بیماران مبتلا به تومور مغزی از نوع آستروسایتوما

Background: Most studies have shown that there are association between the development and malignancy of brain tumors and tumor suppressor genes and oncogenes. The aim of this project was to investigate the P53 gene mutations in exon 8 in patients with astrocytoma type’s brain tumor. Methods: In this present survey, The DNA isolation from 30 samples of brain tissue was done by phenol-c...

Association of Two Polymorphic Codons in P53 and ABCC1 Promoter with Prostate Cancer

Background: In prostate cancer, mutated p53 alleles typically contain missense single-base substitution in codon 72 that resides within exons 5-8. Stable p53 proteins in tumor cell nuclei have been associated with malignancy. A role of p53 is the regulation of drug transporters like ABCC1 (MRP1) by an effect on promoter region. Objectives: The objective of this study was to identify association...

Carrier Determination in a Hemophilia B Family Using Single Strand Conformation Polymorphism (SSCP) and Sequencing

Detection of P 53 gene mutations in exons 5 and 8 in patients of familial breast cancer with PCR-SSCP methode.

 Background: Breast cancer is one of the most common cancer of women in the world.  Although different genetic alteration has been reported in this malignancy, but P 53 gene  mutations has more frequency. P 53 gene is one of the most important suppressor genes and it  play a central role in breast cancer and detecting of mutations in this gene would be very helpful in understanding of genetic m...

Molecular Epidemiology of Breast Cancer among Iranian-Azeri Population based on P53 Research

Background: This study was done in order to enhance our understanding about molecular and epidemiological features of breast cancer among the Azeri population with special emphasis on the detection of TP53 mutations. We also analyzed the role of the P53codon72 polymorphism (rs1042522) and its role in susceptibility to breast cancer. Methods: ...
