To evaluate the role of wild promoter of L-phenylalanine dehydrogenase (PheDH) gene, referred to as pdh, from Bacillus sphaericus in expression, cloning of pdh gene in Bacillus subtilis was performed. The whole pdh gene was cloned in pHY300PLK shuttle vector and amplified, construct (pHYDH) then transformed in B. subtilis ISW1214 and E. coli JM109. The pdh endogenous promoter presented no effec...
Breast cancer is a public health problem in the Western countries. Several studies have shown that BRCA2, like BRCA1 oncosuppressors, are strongly involved in hereditary and sporadic mammary carcinogenesis. It has also been suggested that soy has a protective effect against breast cancer in Asia and, more particularly, phytoestrogens such as daidzein and genistein. Thus, phytoestrogens may have...
background : ovarian cancer is the leading cause of death among gynecological cancers. changes in the methylation of brca1 and brca2 may be an effective mechanism for breast and ovarian cancer. this study evaluates the protein expression and methylation status of brca2 in iranian patients. methods : we assessed 60 mullerian-type ovarian cancers by methylation-specific pcr assays and immunohisto...
Single Nucleotide Polymorphisms (SNPs) in genes involved in the DNA Base Excision Repair (BER) pathway could be associated with cancer risk in carriers of mutations in the high-penetrance susceptibility genes BRCA1 and BRCA2, given the relation of synthetic lethality that exists between one of the components of the BER pathway, PARP1 (poly ADP ribose polymerase), and both BRCA1 and BRCA2. In th...
The aim of this study was to estimate the contribution of deleterious mutations in BRCA1, BRCA2, MLH1, MSH2, MSH6 and PMS2 to invasive epithelial ovarian cancer (EOC) in the population. The coding sequence and splice site boundaries of all six genes were amplified in germline DNA from 2240 invasive EOC cases and 1535 controls. Barcoded fragment libraries were sequenced using the Illumina GAII o...
PURPOSE Several epidemiologic studies have reported that carriers of germline mutations in the BRCA2 gene have an increased risk of prostate cancer, with the highest risk observed in men diagnosed at earlier ages. However, studies of the contribution of BRCA2 mutations to the etiology of hereditary prostate cancer (HPC) have been inconsistent. EXPERIMENTAL DESIGN To further address this issue...
Mutation in homologous recombination repair (HRR) pathway is well established ovarian cancers. Multiple trials have shown variable efficacy prostate Mutations other than BRCA1/BRCA2 been recently reported We describe a unique case of an elderly male with metastatic castration-resistant cancer. He responded to hormonal therapy for 6 months but later progressed. Chemotherapy docetaxel produced se...
the biosynthetic pathways of saturated and unsaturated fatty acids consist of many steps controlled by various enzymes. one of the methods for improving oil quality is to change the fatty acid profile through genetic manipulation which requires isolation and characterization of the genes and other cis-acting elements, such as the promoter, involved in fatty acid biosynthesis. b-ketoacyl-coa syn...
Acatalogue ofmolecular aberrations that cause ovarian cancer is critical for developing and deploying therapies thatwill improve patients’ lives. The Cancer Genome Atlas project has analysed messenger RNA expression, microRNA expression, promoter methylation and DNA copy number in 489 high-grade serous ovarian adenocarcinomas and the DNA sequences of exons from coding genes in 316 of these tumo...
