Objective(s): The aim of the present study was to investigate the effects of genistein and exercise on the spatial memory and expression of microRNA-132, BDNF, and IGF-1 in the hippocampus of ovariectomized rats. Materials and Methods: Sixty animals were divided into six groups of control, sham, ovariectomy (OVX), ovariectomized with 8 weeks of genistein administration (OVX.G), with 8 weeks of ...
Activated macrophages release tissue forms of insulin-like growth factor I (IGF-I), 20-25-kD products of the IGF-I gene, thus providing an extracellular growth and differentiation signal at sites of inflammation. To examine the control of IGF-I gene expression in mononuclear phagocytes, the human macrophage-like cell line U937 was evaluated at rest and after surface activation with phorbol myri...
Insulin receptor substrate-1 (Irs1) is one of the major substrates for insulin and insulin-like growth factor-1 (IGF-1) tyrosine kinases. Systemic Irs1-deficient mice show retardation, with resistance to IGF-1, although underlying mechanisms remain poorly understood. For this study, we generated brain-specific deletion Irs1 (NIrs1KO mice). The NIrs1KO exhibited lower body weights, shorter bodie...
Reprogramming of gene expression contributes to structural and functional adaptation of muscle tissue in response to altered use. The aim of this study was to investigate mechanisms for observed improvements in leg extension strength, gain in relative thigh muscle mass and loss of body and thigh fat content in response to eccentric and conventional strength training in elderly men (n = 14) and ...
Severe cardiovascular diseases, such as myocardial infarction or heart failure, can alter thyroid hormone (TH) secretion and peripheral conversion, leading to low triiodothyronine (T3) syndrome. Accumulating evidence suggests that TH has protective properties against diseases treatment with effectively reduce damage after (MI). Our aim is investigate the effect of T3 pretreatment on cardiac fun...
The formation of oligodendrocytes (oligodendrogenesis) and myelin is regulated by several neurotrophic factors. Strategies to increase the level of these trophic molecules may facilitate repair in demyelinating conditions, such as multiple sclerosis (MS). Because leukocytes are a source of neurotrophic factors, and as glatiramer acetate (GA) generates T helper 2 (Th2) lymphocytes that are not k...
We recently reported increased leg lean mass and strength in men with chronic obstructive pulmonary disease (COPD) receiving 10 wk of testosterone (T) and leg resistance training (R) (Casaburi R, Bhasin S, Cosentino L, Porszasz J, Somfay A, Lewis M, Fournier M, Storer T. Am J Respir Crit Care Med 170: 870-878, 2004). The present study evaluates the role of muscle IGF and related factors as pote...
Wharton’s jelly mesenchymal stem cells (HWJMSCs) hold promise for myocardial regeneration, but optimal treatment regimen (preferably with a growth factor) is required to maximize functional benefits. The aim of this study was to explore the cardioprotective and angiogenesis effects of HWJMSCs combined with insulin-like growth factor-1 (IGF-1) in the treatment of acute myocardial infarction. Th...
تخمدان های 49 ماهی کپور معمولی مولد از فروردین تا مهرماه 1389 نمونه گیری شدند. جهت انجام بخش بافت شناسی تحقیق، قطعات کوچکی از تخمدان ها در محلول ثبوتی بوئن و فرمالین 10% قرار داده شدند. مقاطع بافتی به ضخامت 6- 5 میکرون تهیه شده و توسط h&e، pas، سودان سیاه و تری کروم ماسون رنگ آمیزی شدند. جهت بررسی میزان بیان ژن های igf-1 و tgf-?1 به روشreal- time pcr، قطعات 20- 15 میلی گرمی از تخمدان ها در محلو...
