[Insulin-like growth factor (IGF) receptor in human fetal erythrocytes and fetal rat liver].
In order to clarify the potential role of IGF-I in fetal growth, the dynamics of IGF receptor were investigated in comparison with insulin receptor in human and rat fetuses. In humans, the serum levels of IGF-I measured by IGF-I radioimmunoassay after acid-ethanol extraction were significantly lower in fetuses than in adult controls. Conversely, serum insulin levels in fetuses were not indistin...
متن کاملInsulin-like growth factor-I (IGF-I) and clinical nutrition.
IGF-I (insulin-like growth factor-I) is a peptide hormone, produced predominantly by the liver in response to pituitary GH (growth hormone), which is involved in a wide variety of physiological processes. It acts in an endocrine, paracrine and autocrine manner to promote growth. The production of IGF-I signals the availability of nutrients needed for its anabolic actions. Recently, there has be...
متن کامل[Insulin-like growth factor I (IGF-I) and liver cirrhosis].
Insulin-like growth factor I (IGF-I) is a polypeptide hormone secreted by multiple tissues in response to growth hormone (GH). It is partly responsible for GH activity, and also has glucose-lowering and anabolizing effects. Ninety percent of circulating IGF-I originates in the liver and has autocrine, paracrine, and endocrine effects, the latter on multiple tissues. Liver cirrhosis results in a...
متن کاملExpression of Insulin-like Growth Factor (IGF)-Il and IGF-I Receptor during Proliferation and Differentiation
We have studied the expression of insulin-like growth fador type II (IGF-ll) and its autocrine role during the proliferation and differentiation of the CaCo-2 colon carcinoma cell line. ICE-Il RNA levels were high in proliferating cells and decreased by more than 10-fold when cells ceased to proliferate and differentiated. Immunoreadive ICE-Il protein was high in the conditioned media of prolif...
متن کاملThe use of urinary Insulin-like Growth Factor-I (IGF-I) for determining skeletal age of participants
Introduction: Biochemical markers play an important role in the growth and repair of bone and can be evaluated in different biological fluids. Therefore, the aim of this study was to evaluate the level of insulin-like growth factor-I (IGF-I) in urine as a puberty index and to compare it with cervical vertebral maturational stages (CVMSs) in lateral cephalometry. Materials&Methods: In this cros...
