در این بررسی به‌منظور آگاهی از روند تکاملی و مولکولی توالی نوکلئوتیدی جایگاه ژن FASN در پستانداران شمار 38 رأس گاو هلشتاین شیری (18 رأس کم تولید و 20 رأس پر تولید) انتخاب و خون‌گیری از ورید دمی آنها انجام شد. استخراج DNA از خون کامل به روش فنول-کلروفرم صورت گرفت. واکنش زنجیرهای پلیمراز برای افزایش قطعۀ 750 جفت بازی واقع در ناحیۀ اگزون 37 تا 39 جایگاه ژن FASN با استفاده از جفت آغازگرهای اختصاص...
اسید چرب سنتتاز (FASN)، یک پروتئین چندعاملی است که سنتز اسیدهای چرب را انجام می‌دهد، توسط ژن FASN رمزگذاری می‌شود و یکی از ژن‌های کاندیدای عمده شناخته شده است که نقش اصلی در بازسازی سنتز چربی‌ها در پستانداران ایفا می‌کند. این مطالعه به منظور شناسایی چندشکلی‌های تک نوکلئوتیدی ژن FASN و کاوش ارتباط آنها با سه صفت اقتصادی مهم شامل تولید شیر (M)، فاصله گوساله‌زایی (CI) و نرخ آبستنی (CR) در گاوهای ه...
Fatty acid synthase (FASN) expression is elevated in several cancers, and this over-expression is associated with poor prognosis. Inhibitors of FASN, such as orlistat, reportedly show antitumor effects against cancers that over-express FASN, making FASN a promising therapeutic target. However, large variations in FASN expression levels in individual tumors have been observed, and methods to pre...
Ovarian cancer (OC) is caused by genetic aberrations in networks that control growth and survival. Importantly, aberrant cancer metabolism interacts with oncogenic signaling providing additional drug targets. Tumors overexpress the lipogenic enzyme fatty acid synthase (FASN) and are inhibited by FASN blockers, whereas normal cells are FASN-negative and FASN-inhibitor-resistant. Here, we demonst...
CONTEXT Circulating fatty acid synthase (FASN) is a biomarker of metabolically demanding human diseases. The aim of this study was to determine whether circulating FASN could be a biomarker of overnutrition-induced metabolic stress and insulin resistance in common metabolic disorders. RESEARCH DESIGN AND METHODS Circulating FASN was evaluated in two cross-sectional studies in association with...
Human fatty acid synthase (FASN) is a 270-kDa cytosolic dimeric enzyme that is responsible for palmitate synthesis. FASN is slowly emerging and rediscovered as a marker for diagnosis and prognosis of human cancers. Recent studies showed that FASN is an oncogene and inhibition of FASN effectively and selectively kill cancer cells. With recent publications of the FASN crystal structure and the ne...
The enzyme FASN (fatty acid synthase) is potentially related with hypertension and metabolic dysfunction. FASN is highly expressed in the human placenta. We aimed to investigate the relationship circulating FASN has with blood pressure, maternal metabolism and newborn parameters in healthy pregnant women. Circulating FASN was assessed in 115 asymptomatic pregnant women in the second trimester o...
Fatty acid synthase (FASN) is the enzyme that synthesizes fatty acids de novo in human cells. Although FASN is generally expressed at low levels in most normal tissues, its expression is highly upregulated in many cancers. Consistent with this notion, inhibition of FASN activity has demonstrated potential to halt proliferation and induce cell death in vitro and to block tumor growth in vivo. Co...
Fatty acid synthesis is an important process of the lipogenesis [1]. Fatty acid synthesis is tightly regulated by key enzymes including fatty acid synthase (FASN) [1]. FASN and lipogenesis related enzymes are upregulated in various cancer cells and associated with oncogenic progression [1]. FASN is being an indicator of poor prognosis and a chemotherapeutic target in breast cancers [1]. Fatty a...
Multidrug resistance is a major problem in successful cancer chemotherapy. Various mechanisms of resistance, such as ABC transporter-mediated drug efflux, have been discovered using established model cancer cell lines. While characterizing a drug-resistant breast cancer cell line, MCF7/AdVp3000, we found that fatty acid synthase (FASN) is overexpressed. In this study, we showed that ectopic ove...
