Description

General description

Collagen type I is present in soft connective tissues and bone, where it constitutes more than 90% of the organic matrix.1 During bone formation collagen type I is synthesized from pro-collagen type I, which is secreted from fibroblasts and osteoblasts.2 Pro-collagen type I contains N-and C-terminal extensions, which are removed by specific proteases during the conversion of procollagen to collagen.3 Measurements of N- terminal propeptides of procollagen type I (PINP) can be of value in assessing bone formation. Recent evidence indicates that PINP can serve as a serum biomarker of bone formation, as it accurately identifies those patients who are responding to anabolic or antiresorptive therapy within 3 months of the start of treatment.4 The use of this biomarker in patients being treated for osteoporosis may significantly improve therapy adherence and clinical outcomes.4
