Parathyroid hormone exacerbates pulmonary hypertension through hypoxia-induced parathyroid hormone receptor upregulation.

Pulmonary hypertension (PH) is an incurable right heart failure disease. Parathyroid hormone (PTH) is secreted from the parathyroid gland and plays a crucial role in calcium homeostasis. PTH also acts on the cardiovascular system and affects cardiovascular prognosis. We assessed whether the regulation of PTH affected PH in a hypoxia (Hx)-induced PH mouse model. PTH treatment exacerbated right ventricular hypertrophy and right ventricular systolic pressure in Hx mice. Our data showed how is PTH effected for PH model murine lung. To investigate the regulation of PTH affected PH.Hypoxia (Hx)-induced PH mice were administered PTH daily for 3 weeks.
