The recent report on maternal insulin-like growth factor-I is very interesting. Yang et al. concluded that “maternal serum IGF-I is significantly related to GA, maternal BW, and BMI during pregnancy.” In fact, there are some previous reports on this issue. Pathmaperuma et al. made a completely different observation. In their report, it was reported that serum IGF-I “did not correlate with newbo...

We have prepared by semisynthetic methods a two-chain insulin/insulin-like growth factor I hybrid that contains a synthetic peptide related to residues 22-41 of insulin-like growth factor I linked via peptide bond to ArgB22 of des-octapeptide-(B23-B30)-insulin and have applied the analog to the analysis of ligand interactions with the type I insulin-like growth factor and insulin receptors of p...

PURPOSE To study the growth regulation of bovine corneal endothelium, the effects of insulin and insulin-like growth factor-I on the expression of the c-fos proto-oncogene as well as on DNA synthesis were analyzed. Bovine corneal endothelial cells were also analyzed for the presence of insulin and insulin-like growth factor-I receptors. METHODS Indirect immunofluorescence was used to assess t...

Insulin-like growth factor (IGF)-I and its binding protein IGF binding protein 5 (IGFBP-5) were highly expressed in inflamed and fibrotic intestine in experimental Crohn's disease. IGF-I induced proliferation and increased collagen synthesis by smooth muscle cells and fibroblasts/myofibroblasts in vitro. Here we studied IGF-I and IGFBP-5 in Crohn's disease tissue. Tissue was collected from pati...

Serum insulin-like growth factor-I and insulin-like growth factor binding protein-3 are simply-determined screening analytes if growth hormone deficiency is suspected. The analysis of growth hormone secretion using standardised stimulation tests and secretion profiles is complicated and expensive in comparison. In retrospect, we have examined the value of insulin-like growth factor-I and its bi...
