Background: Procollagen Type 1 N-Terminal Propeptide

Procollagen type I N-terminal propeptide, also called P1NP, is a bone formation marker that is indicative of type I collagen disposition (1). P1NP is generated from the major bone protein Type I Collagen and is cleaved by proteases at the amino (N) terminal and released into the bloodstream (1-3). Typically, P1NP is released in a trimeric form, consisting of two alpha-1 chains and one alpha-2 chain, prior to being broken-down into monomers or fragments (1). Antibodies to P1NP commonly detect the trimeric structure using ELISA or radioimmunoassay applications (1). P1NP is most notably known for being a bone turnover marker, along with CTX-1, and is particularly useful for osteoporosis studies (2-4). While P1NP is used to detect bone formation, C-terminal telopeptide of type I collagen (CTX-1) is contrastingly used for bone resorption (2-4). Bone mineral density (BMD) as measured by dual-energy X-ray absorptiometry (DXA) is a common measurement of osteoporosis status and is frequently used in conjunction with P1NP and CTX-1 levels (2-4). P1NP can be collected and measured either via a blood test or urine test and is beneficial in that its levels are largely unaffected by food intake or circadian rhythms (3-4). One study of postmenopausal females found that the osteoporotic group had significantly higher average P1NP levels (51.7 ng/mL), suggestive of high bone turnover, compared to the normal range in the healthy, control group (38.9 ng/mL) and is inversely correlated with BMD (2). P1NP levels have also been shown to increase following antiresorptive therapy (3). Additionally, P1NP is considered a diagnostic marker for bone metastasis in breast cancer and prostate cancer (5). Specifically, studies found elevated P1NP serum levels is correlated with presence of bone metastasis and skeletal lesions (5).
