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...
Activation of chimeric and full-length growth hormone receptors by growth hormone receptor monoclonal antibodies. A specific conformational change may be required for full-length receptor signaling.
Signal transduction by the growth hormone receptor (GHR) occurs through growth hormone (GH)-induced dimerization of two GHRs to form a trimeric complex. It is thought that dimerization alone is sufficient for signaling, since monoclonal antibodies (mAbs) against the extracellular domain of the GHR elicit proliferation of FDC-P1 cells transfected with a chimeric receptor comprising the extracell...
متن کاملThyroid hormone responsiveness in human growth hormone-related genes. Possible correlation with receptor-induced DNA conformational changes.
Triiodothyronine (T3) induces the transcription of the human chorionic somatomammotropin (hCS) promoter transfected into rat pituitary (GC) cells, but does not stimulate the homologous human growth hormone (hGH) promoter. As demonstrated by forward and reverse mutagenesis, this differential T3 responsiveness is due to subtle structural differences in a T3 response element located between nucleo...
متن کاملNegative regulation of growth hormone receptor signaling.
GH has been of significant scientific interest for decades because of its capacity to dramatically change physiological growth parameters. Furthermore, GH interacts with a range of other hormonal pathways and is an established pharmacological agent for which novel therapeutical applications can be foreseen. It is easy to see the requirement for a number of postreceptor mechanisms to regulate an...
متن کاملAlterations in growth hormone receptor abundance regulate growth hormone signaling in murine obstructive cholestasis.
Children with cholestatic liver diseases, in particular biliary atresia, may develop an acquired growth hormone (GH) resistance. This is characterized by normal GH secretion, reduced liver GH receptor (GHR) abundance, and reduced circulating insulin-like growth factor I (IGF-I). Consequences include linear growth failure, reduced muscle mass, and increased perioperative morbidity and mortality....
