Serum insulin-like growth factors and insulin-like growth factor-binding proteins: clinical implications.

The last decade has been characterized by a major investigative thrust into the physiology of two unique but ubiquitous peptides, insulin-like growth factor (IGF)-I and IGF-II. The regulatory systems that control the tissue bioactivity of the IGFs have been delineated, and subcellular signaling mechanisms have been clarified. Clearly, both tissue and circulating growth factor concentrations are...

Insulin-like growth factor binding proteins modulate Müller cell responses to insulin-like growth factors.

PURPOSE Müller cells are consistently identified in diabetic fibrocontractive ocular tissues and, in response to insulin-like growth factor I, generate tractional forces of the type that cause retinal detachment. Recent studies suggest that diabetes-associated increases in vitreous insulin-like growth factor activity cannot be attributed to simple increases in concentration alone, suggesting th...

Serum insulin-like growth factors, insulin-like growth factor binding proteins, and breast cancer risk in postmenopausal women.

BACKGROUND Studies have shown a positive association between serum insulin-like growth factor (IGF)-I and breast cancer risk in premenopausal but not postmenopausal women. IGF-II and estrogen receptor (ER) status has never been investigated. We examined the association between IGF-I, IGF-II, IGF binding protein (IGFBP)-2, IGFBP-3, and IGFBP-3 protease activity and breast cancer risk in postmeno...

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...

Null association between insulin-like growth factors, insulin-like growth factor-binding proteins, and prostate cancer in a prospective study.

Introduction IGF-1 regulates normal and neoplastic growth in the prostate (1), and higher serum IGF-1 levels (2) appear to increase prostate cancer risk in epidemiological studies. Other aspects of the IGF axis, such as IGFBP-3 (3), inconsistently affect risk. Retrospective studies dominate the literature on this topic, and we, therefore, investigated IGF-I and IGFBP-3 in a pilot study from the...
