زمینه و هدف: دوران بارداری بهعنوان بخش مهمی از زندگی زنان، از جوانب مختلف ازجمله فعالیت بدنی می تواند بر شاخصهای مختلف سلامت نوزاد موثر باشد. یکی از بیماریهای رایج و رو به گسترش زنان سرطان سینه است که BRCA1 و TP53 از شاخصهای مرتبط با آن است. لذا تحقیق حاضر با هدف بررسی تأثیر تمرین هوازی در دوران بارداری در موشهای صحرایی باردار بر بیان ژن BRCA1 و TP53 در بافت پستان فرزندان آنان انجام شد. ر...
Introduction: Breast cancer is one of the leading causes of cancer death in women. Variations in the BRCA1, BRCA2, CDH1, STK11 and TP53 genes increase the risk of developing breast cancer. In addition to specific genetic changes, environmental factors may influence an individual’s risk of developing breast cancer. Lead is one of the most dangerous chemicals in the air as well as many products,...
Breast cancer 1 (BRCA1) and insulin-like growth factor 1 receptor (IGF1R) are critical in ovarian cancer progression. However, the crosstalk between the BRCA1 and IGF1R signaling pathways in ovarian cancer remains largely unknown. The effects of BRCA1 on IGF1R were assessed in 121 serous ovarian cancer patients (BRCA1 mutation, n=30; non-BRCA1 mutation, n=32; hypermethylated BRCA1 promoter, n=2...

مقدمه: سرطان پستان شایعترین سرطان در زنان است. سرطان پستان فامیلی10درصد کل سرطان های پستان را شامل می شوند. جهش های ارثی در دو ژن brca1 و brca2 به عنوان ژن های مستعد کننده سرطان پستان زودرس با نفوذ بالا، شانس ابتلا به این سرطان را تا 87 درصد بالا می برند. brca1و brca2 ژن های سرکوبگر تومور اند که در تعمیر dna نقش مهمی دارند. به نظر می رسد که هر جمعیت و نژادی دارای جهش های ویژه ی خود می باشد. هدف...
The BRCA1 gene product plays numerous roles in regulating genome integrity. Its role in assembling supermolecular complexes in response to DNA damage has been extensively studied; however, much less is understood about its role as a transcriptional coregulator. Loss or mutation is associated with hereditary breast and ovarian cancers, whereas altered expression occurs frequently in sporadic for...
The breast- and ovarian-specific tumor suppressor BRCA1 has been implicated in numerous cellular processes, including transcription, ubiquitination, and DNA repair. Its tumor suppression activity is tightly linked to that of BARD1, a protein that heterodimerizes with BRCA1. It has been previously shown that BRCA1 binds to DNA, an interesting functional observation in light of the genetic data l...
Breast tumors from BRCA1 germ line mutation carriers typically exhibit features of the basal-like molecular subtype. However, the specific genes recurrently mutated as a consequence of BRCA1 dysfunction have not been fully elucidated. In this study, we used gene expression profiling to molecularly subtype 577 breast tumors, including 73 breast tumors from BRCA1/2 mutation carriers. Focusing on ...
PURPOSE The purpose of this study was to investigate the clinical features of epithelial ovarian cancer (EOC) patients according to BRCA1/2 mutation status (mutation, variant of uncertain significance [VUS], or wild type). MATERIALS AND METHODS We analyzed 116 patients whose BRCA1/2 genetic test results were available for mutation type and clinical features, including progression-free surviva...
Inherited mutations in BRCA1 confer susceptibility to breast and ovarian neoplasms. However, the function of BRCA1 and the role of BRCA1 in noninherited cancer remain unknown. Characterization of alternately spliced forms of BRCA1 may identify functional regions; thus, we constructed expression vectors of BRCA1 and a splice variant lacking exon 11, designated BRCA1 delta 672-4095. Immunofluores...
