WebPTHrP is cleaved into N-terminal (1-86) and C-terminal (109-141) peptides, and various attempts have been made to develop assays that target the N-terminal or C-terminal PTHrP peptide. The Nichols Institute of Diagnostics in 1993 first described a sandwich immunoradiometric assay for PTHrP, with a reference range of <0.7 – 2.6 pmol/L. ... Parathyroid hormone-related protein (PTHrP) is a proteinaceous hormone and a member of the parathyroid hormone family secreted by mesenchymal stem cells. It is occasionally secreted by cancer cells (for example, breast cancer, certain types of lung cancer including squamous-cell lung carcinoma). However, it also has normal functions in bone, teeth, vascular tissues and other tissues.
