Using a rat model of chronic renal failure (CRF), we examined insulin-like growth factor I (IGF-I) clearance, degradation, organ distribution, and IGF binding profiles in plasma. The effects of IGF-binding proteins (IGFBP) on IGF clearance and degradation in CRF were studied using the IGF-I analogues des-(1-3)IGF-I and LR3IGF-I, which bind poorly to IGFBP. Although total clearance of IGF-I was not significantly altered in CRF, half-life and area under the curve were increased in the rapid distribution phase and were reduced in the slow elimination phase. Total clearance of LR3IGF-I was significantly increased. Reduced binding of IGF-I in the 150-kDa complex and increased binding to smaller-molecular-weight IGFBP were observed in CRF. Increased degradation of both IGF-I and LR3IGF-I was associated with reduced IGF binding in the 150-kDa complex. The results suggest that the accumulation of lower-molecular-weight IGFBP with reduced IGF binding in the 150-kDa complex, associated with increased degradation of peptide, may explain, at least in part, the reduced bioactivity of IGF-I observed in CRF.
