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...
مقدمه: جهش‌های ژنی BRCA1 و BRCA2 در سلول‌های رده زایا، باعث خطر ابتلاء به سرطان پستان و تخمدان می‌شوند. ژن‌های BRCA1 و BRCA2، عامل 20% از موارد سرطان پستان ارثی هستند. اکثریت جهش‌های موجود در ژن‌های BRCA1 و BRCA2 باعث اتمام زودرس پروتئین می‌شوند. مطالعه حاضر با هدف بررسی نقش جهش‌های BRCA1/2 در ابتلاء به سرطان پستان و معرفی برخی جهش‌های مرتبط با این ژن‌ها انجام شد. روش‌کار: در این مطالعه مروری س...
The aim of this study was to focus on clinicopathological characteristics and prognosis in men with prostate cancer (PCa) harboring a breast cancer 2 (BRCA2) gene mutation and to offer convincing evidence to consider BRCA2 mutation as a marker of poor prognosis in the molecular classification of PCa. We searched relevant articles from PubMed, Embase, Web of Science, and the Cochrane Library dat...
The human DNA mismatch repair gene hMSH2 is involved in the development of sporadic and hereditary nonpolyposis colorectal cancer. An increased risk of colorectal cancer has also been suggested in BRCA1 and BRCA2 mutation carriers. To address the relationship between the expression level of these genes and colorectal tumorigenesis, we studied BRCA1, BRCA2 and hMSH2 mRNA expression by real-time ...
We recently experienced a case of endometrial cancer 5 years after the diagnosis of breast cancer in a patient with a mutation in the BRCA2 gene. A 55-year-old Korean woman who had a past history of breast cancer in her 50s underwent an operation for endometrial cancer. Final pathology confirmed stage Ia, and no adjuvant treatment was performed. After surgery, considering her history of sequent...
Germline mutations in the breast cancer type 2 susceptibility gene (BRCA2) are linked to familial breast cancer and the progressive bone marrow failure syndrome Fanconi anaemia. Established Brca2 mouse knockout models show embryonic lethality, but those with a truncating mutation at the C-terminus survive to birth and develop thymic lymphoma at an early age. To overcome early lethality and inve...
Background and Aim: Different regulation processes have an effect on osteoblastic differentiation of mesenchymal stem cells (MSCs), and among them Wnt signaling pathway is particularly desirable. In Wnt signaling pathway, Adenomatous Polyposis Coli (APC) bind to β-catenin and induce its degradation, thereby acting as a negative regulator of canonical Wnt pathway. In this study, gene expression ...
Objective: Identity the genetic aspects and major gene influence on energy balance, milk production, fertility, food safety and consumer are the recent interests of genetic and breeding researchers. Methods: Najdi Cattle is the most prominent breeds in Khuzestan province. To do this plan in Shoushtar Najdi Cattle Station, blood samples were taken from 15 Najdi Cattles. DNA was extracted from wh...
background:estrogens play a substantial role in the proliferation, progression and treatment of breast cancer by binding with two estrogen receptors, alpha and beta (erα and erβ). resistance to endocrine therapy is a major problem in the treatment of breast cancers and, in some cases, may be related to loss of er gene expression. we have already showed that erα methylation occurs in high freque...
This is by far the largest study of its kind to date, and further suggests that AIB1 does not play a substantial role in modifying the phenotype of BRCA1 and BRCA2 carriers. The AIB1 gene encodes the AIB1/SRC-3 steroid hormone receptor coactivator, and amplification of the gene and/or protein occurs in breast and ovarian tumors. A CAG/CAA repeat length polymorphism encodes a stretch of 17 to 29...
