Parathyroid hormone-related protein (PTHrP) gene expression in solid tumours associated with normocalcaemia and hypercalcaemia

Parathyroid hormone‐related protein (PTHrP) is an important humoral factor in the syndrome of humoral hypercalcaemia of malignancy (HHM) and its importance is evident by the many studies examining either PTHrP mRNA expression, intracellular peptide, or circulating PTHrP levels in patients with malignancy. However, the relationship between PTHrP mRNA expression, intracellular localization of peptide, and circulating PTHrP levels in the same group...
