Insulin-like growth factor 1 mediates negative feedback to somatotroph GH expression via POU1F1/CREB binding protein interactions.

Circulating insulin-like growth factor 1 (IGF-1) has been shown to act as a negative feedback regulator of growth hormone (GH) gene expression; however, the mechanism of this negative feedback is poorly understood. Activation and regulation of GH gene expression require the binding of the transcription factor POU1F1 to the GH promoter along with cyclic AMP (cAMP) response element binding protei...

Vertex balding, plasma insulin-like growth factor 1, and insulin-like growth factor binding protein 3.

BACKGROUND A recent report suggested that men with vertex balding have higher levels of plasma insulin-like growth factor 1 (IGF-1). The association of its major carrier protein, insulin-like growth factor binding protein 3 (IGFBP-3), with male pattern hair loss has not been examined. OBJECTIVE We evaluated the relations of plasma concentrations of IGF-1 and IGFBP-3 with vertex balding in mid...

Insulin-like growth factors sustain insulin-like growth factor-binding protein-5 expression in osteoblasts.

Insulin-like growth factors (IGFs) I and II are considered to be autocrine regulators of bone cell function. Recently, we demonstrated that IGF-I induces IGF-binding protein-5 (IGFBP-5) expression in cultures of osteoblast-enriched cells from 22-day fetal rat calvariae (Ob cells). In the present study, we postulated that IGFs play an autocrine role in the maintenance of IGFBP-5 basal expression...

Insulin-like growth factor-binding protein-1 and prostate cancer.

There is growing and persuasive evidence, both experimental (1–4) and epidemiologic (5–7), that the peptide hormone insulin-like growth factor-I (IGF-I) is a critical factor in the development of prostate cancer. Because of their central role in the regulation of bioavailable IGF-I, the insulin-like growth factor-binding proteins (IGFBPs) have also come under scrutiny as potential mediators of ...

Immunoassay of insulin-like growth factor binding protein-1.

Accurate measurement of insulin-like growth factor (IGF) binding protein-1 (IGFBP-1) is important for precise definition of its physiological roles and potential diagnostic values. Because altered phosphorylation results in altered IGFBP-1 immunoreactivity, current assays may significantly underestimate or fail to detect physiological changes in the IGFBP-1 concentrations. We developed three EL...
