WebPTH is packaged into either secretory granules for exocytosis or storage granules. Secretion of de novo synthesized PTH is believed to occur within 30 min of prepro-PTH formation … WebWe studied the effect of PTH (10–100 nM) on transductive mechanisms (adenylate cyclase activity, Ca 2+ metabolism, IP 3 levels) in cell cultures derived from normal and otosclerotic human bone fragments. The cultured cells were osteoblast-like but with calcitonin-receptors still present and with PTH receptors coupled with the adenylate cyclase system.
