Vitamin D 17-26 parathyroid hormone Rattus norvegicus 50-69 25294851-8 2015 Importantly, in rat SHPT, the correction of vitamin D deficiency effectively reversed the resistance to paricalcitol induction of C/EBPbeta to suppress ADAM17 expression and PTG enlargement, reducing PTH by 50%.

Vitamin D 61-70 parathyroid hormone Rattus norvegicus 86-89 2212016-3 1990 PTH mRNA levels were increased by 3 wk of calcium deficiency (five times), a vitamin D-deficient diet (two times), and combined deficiency (10 times), but not changed by high calcium.
