Non-islet cell tumor hypoglycemia (NICTH) is a rare paraneoplastic syndrome in which secretes high molecular weight (“big”) IGF-2, causing hypoglycemia. Big IGF-2 product of abnormal processing precursors with defective gene transcription and expression. Tumors involved are usually mesenchymal, vascular, or epithelial origin have burden. We report an unusual case NICTH patient concomitant spind...

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 ...

Background: Morphine is wildly used as a painkiller in clinics, but causes several side effects such as hyperalgesia, depression and more notably amnesia. Here, we assumed that insulin-like Growth Factor-1 (IGF-1) as a peptide with widespread distribution of receptors in brain regions, especially hippocampus, might be capable to alleviate morphine-induced amnesia. Meth...

As a tool for measuring the aging process, life span has been invaluable in dissecting the genes that modulate longevity. Studies over the past few decades have identified several hundred genes that can modify life span in model organisms such as yeast, worms, and flies. Yet, despite this vast amount of research, we still do not fully understand how the genes that affect life span influence how...

growth hormone and insulin-like growth factor 1 are anabolic hormones which play a vital role in developing body tracts especially in childhood and adolescence years. exercise is a motive which influences gh and igf-1 secretion. today, water sports are highly recommended due to creating delight in children. therefore, the purpose of this study was to examine the effect of eight weeks of water t...

in teleosts the insulin-like growth factor-i, a member of igf system, play an important role in the control of growth and reproduction including metabolism, cell division, oogenesis, final oocyte maturation and secretory activity. this system is controlled by several hormones and metabolic status. serum igf-i, thyroxine (t4) and cortisol levels were studied in two female brood stocks (caught fr...
