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 کاملPotentiation of cytotoxic chemotherapy by growth hormone-releasing hormone agonists.
The dismal prognosis of malignant brain tumors drives the development of new treatment modalities. In view of the multiple activities of growth hormone-releasing hormone (GHRH), we hypothesized that pretreatment with a GHRH agonist, JI-34, might increase the susceptibility of U-87 MG glioblastoma multiforme (GBM) cells to subsequent treatment with the cytotoxic drug, doxorubicin (DOX). This con...
متن کاملGrowth hormone releasing hormone or growth hormone treatment in growth hormone insufficiency?
Sixteen prepubertal children who were insufficient for growth hormone were treated with growth hormone releasing hormone (GHRH) 1-40 and GHRH 1-29 for a mean time of nine months (range 6-12 months) with each peptide. Eleven children received GHRH 1-40 in four subcutaneous nocturnal pulses (dose 4-8 micrograms/kg/day) and eight (three of whom were also treated with GHRH 1-40) received GHRH 1-29 ...
متن کاملRadioprotection and Molecular Therapy
The dose limiting toxicities of Ionizing Radiation (IR) in radiosensitive normal tissues, such as bone marrow, intestine, and skin, precludes the delivery of curative or effective palliative doses of radiation in many cases. Despite of the intense research effort in the past to find new effective and well-tolerated radioprotectors, only one drug has been approved by FDA for this indication. One...
