PLP in atrial secretory vesicles suggests possible cardiac endocrine role; leaves open any human physiologic or clinical relevance.
p-value: p=<0.001
Deftos et al. (1993) studied Normal cardiac physiology (n=9). Atrial cardiac tissue vs. Ventricular cardiac tissue was evaluated on Parathyroid hormone-like protein (PLP) concentration and secretion (p=<0.001). Parathyroid hormone-like protein is present in secretory vesicles of atrial myocytes, with atria containing and secreting significantly higher concentrations than ventricles (P<0.001).
