Abstract (sommario):

Abstract. Binding of 125I-insulin-like growth factor-I and 125I-ovine somatomedin-C/IGF-I to monolayer cultures of muscle-derived ovine fibroblasts is described. Preliminary competitive binding experiments indicate that ovine fibroblasts possess independent cell surface receptors for IGF-I. Affinity of rIGF-II for IGF-I binding sites is minimal; rIGF-II binds to Type I IGF receptors at 1/1000 the strength of IGF-I. Insulin binds to the Type I IGF receptor at 1/100 the strength of IGF-I, whereas ovine somatomedin-C/IGF-I displays equivalent IGF-I binding as evidenced by overlapping competition

ABSTRACT The application of a human somatomedin-C radioimmunoassay for the determination of somatomedin-C in chicken plasma has been examined. Parallel inhibition of binding of 125I-labelled somatomedin-C to antisera raised against somatomedin-C was observed with acid-treated human and chicken plasma. The concentration of immunoreactive (IR)-somatomedin-C in the plasma of the domestic fowl appears to be GH dependent. Plasma concentrations of IR-somatomedin-C were reduced after hypophysectomy and partially restored by replacement therapy with chicken GH. The age/development pattern of circulati

ABSTRACT A human primary haemangiosarcoma was derived from a patient with severe hypoglycaemia. Cell line established from that tumour secreted somatomedin C in serum-free culture media. Immunoreactive somatomedin from the media eluted from Sephacryl S-200 in two peaks of 160 000 and 8000 molecular weights. Similar results were obtained when medium was acidified and chromatographed on Sephadex G-50. Binding of tracer concentrations of 125I-labelled somatomedin C to human haemangiosarcoma cells was much higher than that of 125I-labelled insulin. Half-maximal displacement of 125I-labelled somato

Abstract (sommario):

ABSTRACTSomatomedin C and other hormones, as well as blood metabolites, were measured during the dry period and during lactation in dairy cows, given different amounts of energy and protein, to study metabolic and endocrine adaptations. Somatomedin C, specifically measured by radioimmunoassay after separation from its binding protein, did not exhibit typical diurnal variations, in contrast to somatotropin and insulin, which increased particularly after concentrate intake. Somatomedin C markedly decreased at parturition and reached lowest values around the peak of lactation, while levels of som

The mechanisms by which triiodothyronine (T3) stimulates growth and maturation of growth-plate cartilage in vitro were studied by incubating embryonic chick pelvic cartilages in serum-free medium in the presence and absence of T3 for 3 days. To determine whether T3 might stimulate production of somatomedins by the cartilage, medium from cartilage incubated with and without T3 was assayed for somatomedin C (Sm-C) by radioimmunoassay. No difference in Sm-C content was found. However, cartilage incubated with T3 and increasing amounts of human Sm-C (0.5-20 ng/ml) weighed more and had greater amou

Abstract. Human somatomedins (Sm) are heterogeneous on separation by chromatofocussing. Besides the 'classic' insulin-like growth factor I and II (IGF-I/Sm-C and IGF-II), a number of minor peaks emerge which can be classified as IGF-I/Sm-C-like or as IGF-II-like. The aim of the current study was to investigate whether or not polymorphism of somatomedins is present in individuals and whether or not the polymorphic pattern changes during development. Serum extracts from normal healthy children and adults were fractionated by chromatofocussing and the various somatomedin-like peptides were quanti

It was concluded that fetal somatomedin-like activity is not GH dependent. After hypophysectomy fetal lambs showed no reduction in body weight or length at term. J. Endocr. (1985) 104, 193–199

Abstract (sommario):

Abstract Since the original somatomedin hypothesis was conceived, a number of important discoveries have allowed investigators to modify the concept. Originally somatic growth was thought to be controlled by pituitary GH and mediated by circulating insulin-like growth factor-I (IGF-I, somatomedin C) expressed exclusively by the liver. With the discovery that IGF-I is produced by most, if not all, tissues, the role of autocrine/paracrine IGF-I vs. the circulating form has been hotly debated. Recent experiments using transgenic and gene-deletion technologies have attempted to answer these questi

Abstract (sommario):

It has been reported that there is a striking homology between the basic insulin-like growth factors (IGF) – somatomedins (SM) found in humans and rats. The radioimmunoassay (RIA) developed for the human hormone IGF-I (basic somatomedin, B-SM) can measure immunoreactive IGF-I in rat serum (IrIGF-I). Using this RIA, the profile of serum IrIGF-I was measured at each day of gestation in groups of inbred and Charles River Wistar rats. In each case IrIGF-I showed a gradual increase in early and mid gestation followed by a sharp decrease that occurred late in gestation to values 20–40% of control. T

Abstract. Selenium intake (5.0 ppm) induces growth retardation, accumulation of selenium in somatotrophs, lack of growth hormone response to GHRH and an 80 per cent reduction in serum somatomedin C in infant rats. In addition, it induces a slight reduction in serum albumin and occasionally slight central liver necrosis. In order to determine the role of insufficient growth hormone production, the influence of exogenous growth hormone was studied during selenium intake in groups of rats during 25 to 46 days of age (post-weaning).

Abstract. Six somatomedin-like peptides were purified from human plasma Cohn fraction IV by a six-step procedure which included ethanol precipitation, reversed-phase extraction, gel filtration, chromatofocusing and reversed-phase high pressure liquid chromatography (HPLC). Purification was monitored with a competitive protein binding assay using a crude preparations of somatomedin carrier protein. The peptides isolated were homogeneous by reversed-phase HPLC and sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). Their apparent isoelectric points determined by chromatofocusi

Abstract (sommario):

The ubiquitous nucleotide pyrophosphatases/phosphodiesterases NPP1–3 consist of a short intracellular N-terminal domain, a single transmembrane domain and a large extracellular part, comprising two somatomedin-B-like domains, a catalytic domain and a poorly defined C-terminal domain. We show here that the C-terminal domain of NPP1–3 is structurally related to a family of DNA/RNA non-specific endonucleases. However, none of the residues that are essential for catalysis by the endonucleases are conserved in NPP1–NPP3, suggesting that the nuclease-like domain of NPP1–3 does not represent a second

Abstract (sommario):

ABSTRACT Daily changes in the concentrations of plasma corticosterone, prolactin, thyroid hormones and somatomedin C were measured in 28-day-old fat and lean lines of broilers produced by selection for high and low concentrations of very low density lipoproteins (VLDL). The effects of daily injections of corticosterone on the concentrations of these hormones and on fattening were compared in the two lines. The selection procedure had no effect on the concentrations of any of the hormones. However, daily rhythms in concentrations of plasma corticosterone, tri-iodothyronine (T3) and prolactin we
