Background and Objective: Apoptosis plays a key role in the pathogenesis of a variety of cardiovascular diseases, especially cardiac failure. Therefore, the purpose of this study was investigating the effect of Origanum vulgare extract supplementation with and without exercise training on p53 and cytochrome c gene expression in myocardium of male rats. Materials and Methods: Nineteen three-...
Objectives and Background: Mutation directed inactivation of the tumor suppressor gene p53 have been found incountries with high frequency for hepatocellular carcinomas (HCCs). Our goal in the present study was screening of the p53 gene in tumor tissues from HCC affected individuals in southwest Iran for putative mutations in exons 7 and 8 that are known as hot spot regions. Materials & Met...
the p63 gene, a member of the p53 gene family, is expressed into at least six protein isoforms.the transcription factor p63 is a homologue of the tumor suppressor p53. unlike p53, which is dispensable for normal development, p63 is critical for the development of stratified epithelial tissues such as epidermis, breast, and prostate. p63, , is transcribed from two different promoters giving rise...
Background and Objectives: Breast cancer (BC) is the most common invasive malignancy affecting women worldwide. The tumor-suppressor P53 gene (P53) is frequently mutated in breast tumors. To use P53 as a target for therapy, it is important to accurately assess p53 mutation status in tumor samples. Materials and Methods: A total of 102 tumor samples were collected from breast cancer patients ref...
Introduction: The use of drug delivery systems can increase the effectiveness of chemotherapy and reduce its side effects in the treatment of breast cancer. This study aimed to evaluate the effect of doxorubicin-containing silk fibroin nanoparticles (NF-DOX) on P53 gene expression in breast cancer cell lines and to measure its toxicity in vitro. Methods: NF-DOX was synthesized and characterize...
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 ...
The objective of the present study was to compare P53 protein expression in aggressive and non-aggressive Basal Cell Carcinoma(BCC). BCC is the most common skin cancer in whites and is seen in men more than in women. P53 is a tumor suppressor gene and has role in cell growth control. Mutation in this gene leads to loss of cell growth control and, therefore, malignancy. Various studies...
Backround: The present study investigated the correlation between p53 gene codon 72 polymorphism and 6 other genetic single nucleotide polymorphisms (SNPs) in patients with cervical cancer infected by HPV. Methods: 450 patients with cervical cancer (280 Squamous cell carcinoma and 170 Adenocarcinoma) were followed at hospitals in Iran from Dec. 2014 to Apr. 2015. Moreover, 100 age/sex-matche...
Introduction: Human hematopoietic stem cells (hHSCs) have been used for transplantation in hematologic failures. Because the number of hHSCs per cord blood unit is limited, the expansion of these cells is important for clinical application. It has been reported that cytokines and feeder layer provide a perspective to in vitro expansion of hHSCs. In this regard, cord blood CD34+ cells ex...
Many studies have been focused on cytogenetic and molecular genetic defects in brain tumors; therefore the role of ATM as a tumor suppressor gene in these tumors is poorly considered. In this study mutation analysis of exon 19 and 39 of ATM gene and P53 accumulation were investigated by PCR-SSCP, sequencing, and flow cytometry . Four polymorphisms including D1853N, IVS 38-8 T?C, F858L, P872T we...
