We examined the effects of two levels of gestational undernutrition (50 % and 40 % of ad libitum) on postnatal growth rate, skeletal muscle cellularity and the expression of genes that control muscle growth, in the offspring at weaning. The results showed that the rat pups born to mothers fed the 50 % diet during gestation and a control diet during lactation had an increased postnatal growth ra...
The insulin receptor-related receptor (IRR) gene encodes a protein that is homologous to the receptors for insulin and insulin-like growth factor-I (IGF-I). We have cloned a full-length cDNA encoding the human IRR by screening a human kidney cDNA library. The nucleotide sequence of our cDNA is identical to the sequence predicted from the human IRR gene except for the presence of an insertion of...
سابقه و هدف: فاکتور‌های نروتروفیک مشتق از مغز (BDNF) و رشد شبه انسولینی-1 (IGF-1) دارای دامنه وسیعی از فعالیت‌های زیستی هستند که تحت تأثیر چاقی دوران کودکی قرار می‌گیرند. لذا هدف از مطالعه حاضر بررسی اثر هشت هفته‌ای مصرف ویتامین C و تمرین هوازی بر سطوح BDNF و IGF-1 سرمی در دختران چاق بود. مواد و روش‌ها: در این تحقیق نیمه تجربی، 28 دختر چاق انتخاب و به طور تصادفی به چهار گروه کنترل، تمرین، ویتام...
Introduction Insulin-like growth factor I (IGF-I) which is produced in abundance in the normal adult liver, is deeply involved in hepatocyte survival, growth, and differentiation during liver development. IGF-I plays the roles via the receptor (IGF-IR) signaling pathway. IGF-IR unlike IGF-I is expressed strongly in the developing liver, but much more weakly in adults. Objective: We hypothesi...
Muscle wasting affects large numbers of people, but few therapeutic approaches exist to treat and/or reverse this condition. The beta(2)-adrenoceptor agonist clenbuterol produces a muscle-specific protein anabolism in both normal and catabolic muscle and has been used to limit muscle wasting in humans. Because clenbuterol appears to interact with or mimic innervation, its effect on the expressi...
We applied K-means cluster analysis to test the hypothesis that muscle-specific factors known to modulate protein synthesis and satellite cell activity would be differentially expressed during progressive resistance training (PRT, 16 wk) in 66 human subjects experiencing extreme, modest, and failed myofiber hypertrophy. Muscle mRNA expression of IGF-I isoform Ea (IGF-IEa), mechanogrowth factor ...
Histone deacetylases (HDACs) affect cell growth at the transcriptional level by regulating the acetylation status of nucleosomal histones. HDAC inhibition induces differentiation and/or apoptosis in transformed cells. We recently showed that HDAC inhibitors, such as suberoylanilide hydroxamic acid (SAHA), potently induce apoptosis of human multiple myeloma (MM) cells. In this study, we focused ...
هدف از انجام این پژوهش، ارزیابی اثر فاکتور رشد شبه انسولین- یک ( igf-1 ) در محیط کشت آزمـایشگاهی بـر قابلیت تکویـن رویـان هـای گـاوی تولید ش«ده از اووسیتهای تحت تنش گرمایی بود. اووسیتهای نابالغ به طور تصادفی به دو گروه تقسیم شدند و 12 ساعت اول دوره بلوغ آزمایشگاهی را در 5/38 یا 41 (گروه تنش گرمایی) درجه سانتی گراد و 12 ساعت دوم را در 5/38 درجه سانتی گراد سپری کردند. بعد از بلوغ و لقاح آزمایشگ...
Insulin-like growth factor I (IGF-I) is a widely distributed mitogen that mediates the growth-promoting effects of platelet-derived growth factor in mesenchymal cells. We show that rat aortic IGF-I messenger RNA (mRNA) is induced 24 hours after deendothelialization, at a time when smooth muscle cell proliferation within the intima is still not apparent. After 7 days, IGF-I mRNA induction peaks ...
