molecular genetics selection on individual genes is a promising method to genetically improve economically important traits in livestock. the insulin like growth factor-i (igf-i) gene may play important roles in growth of multiple tissues, including muscle cells, cartilage and bone. the objectives of the present study were the estimate the haplotype frequencies of the igf-i gene polymorphisms i...
Aim Insulin-like growth factor 1 (IGF-1), which is primarily produced in hepatocytes and associated with liver functional reserve, plays a crucial role the pathological condition of cirrhosis. This study aimed to investigate usefulness serum IGF-1 levels for predicting long-term prognosis decompensation development patients Methods We retrospectively evaluated 148 cirrhosis divided them into th...
راویداکت اندام هدفی برای هورمون های استروژن و پروژسترون تولید شده در پاسخ به هورمون های lhو fsh تخمدان است. بنظر می رسد عمل پرو/زسترون وابسته به نوع سلول مورد استفاده در هم کشتی باشد. استروژن ممکن است بر رشد اولیه جنین از طریق مکانیسم های مختلف که توسط نوع سلولهای موجود واسطه می شود تاثیر داشته باشد. استروئیدها تنظیم کننده های اصلی عملکرد سلولی شامل رشد و تمایز در لوله تناسلی هستند. اثرات هورمو...
مقدمه: انسولین در مغز نقشی در انتقال گلوکز به نورون‌ها ندارد، ولی با واسطه‌ی گزارش از بافت‌های محیطی به مغز جذب می‌شود که بر بقا و عملکرد نورون‌ها تأثیرگذار است. در مدل‌های حیوانی مقاوم به انسولین، جذب انسولین از بافت‌های محیطی به مغز کاهش می‌یابد. با توجه به این که عامل رشد شبه انسولینی (IGF-I) نیز به موازات انسولین و با واسطه‌ی گیرنده‌ی انسولین در مغز عمل می‌کند، بیان آن در بیشتر مناطق مغز مو...
Background & Aims: Malignant neoplasm of the colon wall or colon cancer (or colorectal cancer) is the fourth and third most common cancer in men and women worldwide, respectively. Risk factors for colon cancer are complex and the drug therapies did not have a great survival chance. Regarding the probable role of the physical activity in preventing the incidence and severity of cancer, the prese...
Background & Aims: Retinopathy of prematurity (ROP) is one of the most causes of retinal detachment and blindness. Although many studies have been conducted on the pathophysiology of ROP, the exact mechanism is yet under investigation. This study aimed at evaluating the role of serum vascular endothelial growth factor (VEGF), insulin like growth factor-I (IGF-I), and its binding protein (IGFBP-...
Background & Objective: Prostate cancer is the most common cancer in men. The purpose of this study was to determine the effect of combined training (aerobic-resistance) on serum levels of insulin-like growth factor-I (IGF-I) and insulin-like growth factor-binding proteins 3 (IGFBP-3) in men with prostate cancer. Materials & Methods: 20 eligible men with prostate cancer with an average age...
An efficient expression system in Escherichia coli for several biologically active insulin-like growth factor-I (IGF-I) fusion peptide analogues is described. These novel IGF-I fusion protein analogues have properties that make them very useful reagents in the investigation of IGF-I action. The analogues comprise an IGF-I sequence and the first 11 amino acids of methionyl porcine growth hormone...
Zinc (Zn(2+)), a multifunctional micronutrient, was recently shown to lower the affinity of cell-associated insulin-like growth factor (IGF) binding protein (IGFBP)-3 and IGFBP-5 for both IGF-I and IGF-II, but to increase the affinity of the cell surface type 1 IGF receptor (IGF-1R) for the same two ligands. However, there is a need for data concerning the effects of Zn(2+) on soluble IGFBPs an...
