WebCauses of primary hyperparathyroidism include: A noncancerous (benign) growth, called an adenoma, forms on a single parathyroid gland. The adenoma causes the gland to overact and make more PTH. This is the most common cause. Two or more of your parathyroid glands become enlarged, a condition called hyperplasia, and produce too much hormone. WebIn renal epithelium, PTH promotes conversion of Vitamin D to its active form, lowers Ca ++ excretion and increases phosphate excretion (1, 2, 9). PTH also increases hematopoietic stem cell proliferation and mobilization and induces arterial vasodilation by regulating Ca ++ influx in PTH1R-expressing arterial smooth muscle (8, 13). northern spotted owl r adult size
