تأثیر پلی مورفیسم های ژن های هورمون رشد growth hormone و گیرنده ژن هورمون رشد growth hormone receptor روی برخی صفات اقتصادی بز مرغز ایران
در این پژوهش به بررسی وجود پلی مورفیسم در ناحیه پروموتور و اگزون 10 ژن های gh و ghr و ارتباط آنها با صفات رشد در بزهای مرغز پرداخته شد. بدین منظور از سیاهرگ وداج تعداد 160 بز مرغز موجود در ایستگاه اصلاح نژاد استان کردستان خونگیری و dna نمونه ها با استفاده از کیت استخراج گردید. قطعه 391 جفت بازی از ژن gh و 361 جفت بازی از ژن ghr تکثیر شدند. از تفاوت چندشکلی فضایی تک رشته ها (sscp) و توالی یابی ب...
Somatostatin regulates hepatic growth hormone sensitivity by internalizing growth hormone receptors and by decreasing transcription of growth hormone receptor mRNAs.
Somatostatins (SSs), a diverse family of peptide hormones, have been shown to inhibit the release of growth hormone (GH) from the pituitary. In this study, we used rainbow trout to determine whether or not SSs affect growth in an extrapituitary manner, in particular, by decreasing GH sensitivity in liver. SS-14 significantly decreased hepatic GH binding in fish implanted (5.8 x 10(-11) mol/h) f...
متن کاملNew insights into growth hormone receptor function and clinical implications.
Although used as a therapeutic for 50 years, it is only recently that the application of molecular techniques has provided a basis for understanding growth hormone's (GH) clinical actions. This article reviews progress in our current knowledge of the molecular mechanism of growth hormone (GH) receptor activation based on a number of physicochemical techniques, and documents insights gained into...
متن کاملInsights from growth hormone receptor blockade.
Pegvisomant is a genetically manipulated growth hormone (GH) that disables signal transduction through the GH receptor and thus functions as a GH receptor antagonist. In a series of studies of the metabolic effects of GH in healthy male individuals, pegvisomant has been used to create a model of acute GH deficiency but without the typical alterations in body composition. This review summarizes ...
متن کاملPersian sturgeon growth hormone elaboration and purification
In this study Escherichia coli DE3 containing expression vector (pET21a) with cloned Persian sturgeon growth hormone (psGH) gene was grown in 10 mL LB broth on a 150 rpm shaker, at the temperature of 37 °C. At the late log phase (determined by OD standard curve) 100 &muL isopropyl &beta-D-1-thiogalactopyranoside (IPTG) was added for induction of GH synthesis. Samples were taken every 2 hours an...
