DNA methyltransferase inhibitor, 5-azacitidine (AC) is effective in myelodysplastic syndromes (MDS) and can induce re-expression in cancer. We analyzed the methylation of 25 tumor suppressor genes in AC-treated MDS. Hypermethylation of CDKN2B, FHIT, ESR1, and IGSF4 gene was detected in 9/44 patients. In concordance with the clinical response, a lack of or decreased methylation in 4 patients wit...
مقدمه : شواهد نشان میدهد که پلی مورفیسم در ژن گیرنده استروژن- (ESR1) a با سرطان پستان و اشکال با ل ینی آن در میان سفید پوستان ارتباط مستقیم دارد. مطالعات اپیدمیولوژی نشان میدهد که سن ابتلا به بیماری در میان سفید پوستان خاور میانه و غربی متفاوت است. در این مطالعه پلی مورفیسم در ژن ESR1 و ارتباط آن با خطر ابتلا به سرطان پستان در ایران مورد بررسی قرار گرفته است. مواد و روشها : نوع مطالعه مورد ...
Oestrogen is known to affect multiple aspects of human health, including complex traits such as cardiovascular disease, cancer, fracture risk, arthritis, behaviour and Alzheimer’s disease. Oestrogen receptor a (ESR1), one of two known oestrogen activated transcription factors, is expressed throughout many tissues. It can regulate gene expression by both oestrogen-dependent and oestrogenindepend...
Approximately 80% of human breast carcinomas present as oestrogen receptor a-positive (ER+ve) disease, and ER status is a critical factor in treatment decision-making. Recently, single nucleotide polymorphisms (SNPs) in the region immediately upstream of the ER gene (ESR1) on 6q25.1 have been associated with breast cancer risk. Our investigation of factors associated with the level of expressio...
Understanding the mechanisms by which estrogens affect cardiovascular disease risk, including the role of variation in the gene for estrogen receptor alpha (ESR1), may be key to new treatment strategies. We investigated whether the CC genotype at ESR1 c.454-397T>C is associated with increased risk among men. Study of more than 7000 whites in 5 cohorts from 4 countries provided evidence that gen...
BACKGROUND Although host immune response is an emerging prognostic factor for colorectal cancer, there is no consensus on the optimal methodology, surrogate markers or tissue for study. PATIENTS AND METHODS Tumour blocks were prospectively collected from 344 patients with stage II/III colorectal cancer (CRC) treated with adjuvant chemotherapy. Whole section lymphocytic infiltration was studie...
Left ventricular (LV) mass and other LV measures have been shown to be heritable. In this study we hypothesized that functional variation in the gene coding for estrogen receptor-alpha (ESR1), known for mediating the effect of estrogens on myocardium, is associated with age-related changes in LV structure. Four genetic markers (ESR1 TA repeat; rs2077647, or +30T>C; rs2234693, or PvuII; and rs93...
Background: The major issue to address in endometriosis etiology is to identify the genetic changes in the disease and their occurrence in different populations. Uncovering these genetic changes may be important in developing potential biomarkers for early diagnosis and prognosis of endometriosis. Among all endometriosis susceptibility genes studied before, convincing association has been found...
Susceptibility to breast cancer is significantly increased in individuals with germ line mutations RECQ1 (also known as RECQL or RECQL1), a gene encoding DNA helicase essential for genome maintenance. We previously reported that expression predicts clinical outcomes sporadic patients stratified by estrogen receptor (ER) status. Here, we utilized an unbiased integrative genomics approach delinea...
