Effects of retinoic acid on growth hormone-releasing hormone receptor, growth hormone secretagogue receptor gene expression and growth hormone secretion in rat anterior pituitary cells

Comparison of Expression of Growth Hormone-Releasing Hormone and Its Receptor Splice Variant 1 in Different Stages of Endometriosis

Pituitary-specific expression and Pit-1 regulation of the rat growth hormone-releasing hormone receptor gene.

The GHRH receptor is expressed in the somatotroph cell of the anterior pituitary, where it functions to mediate GHRH-stimulated GH release. To study pituitary and somatotroph cell-specific expression of this gene, a transgenic mouse model and complementary cell culture experiments were developed. The activity of the 1.6-kb proximal rat GHRH receptor promoter was examined in vivo by generating t...

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...

Atrazine Binds to the Growth Hormone–Releasing Hormone Receptor and Affects Growth Hormone Gene Expression

BACKGROUND Atrazine (ATR), a commonly used herbicide in the United States, is widely distributed in water and soil because of its mobility through ecosystems and its persistence in the environment. ATR has been associated with defects in sexual development in animals, but studies on mammalian systems have failed to clearly identify a cellular target. OBJECTIVES Our goal in this study was to i...

Pituitary growth hormone and growth hormone-releasing hormone receptor genes and associations with mammographic measures and serum growth hormone.

BACKGROUND Mammographic density is a strong risk factor for breast cancer that is heritable and associated with blood levels of growth hormone and insulin-like growth factor-I (IGF-I). We tested single nucleotide polymorphisms (SNP) in pituitary growth hormone (GH1) and growth hormone-releasing hormone receptor (GHRHR) genes for an association with mammographic density, hormones of the growth h...
