Endocrinology·2022

Parathyroid hormone (PTH) research evolved over a century, revealing its crucial role in calcium regulation. Surprisingly, PTH can now be used to build bone, offering new osteoporosis treatments.

Area of Science:

  • Endocrinology
  • Calcium and Bone Biology

Background:

  • Parathyroid hormone (PTH) research spans over a century.
  • Early work established PTH's role in calcium homeostasis and gland function.
  • Understanding PTH's pathophysiology in excess (bone loss) and deficiency (hypocalcemia) followed.

Purpose of the Study:

  • To review the historical progression of parathyroid hormone (PTH) research.
  • To highlight key discoveries in PTH structure, receptor identification, and physiological actions.
  • To discuss the therapeutic implications of PTH in bone building.

Main Methods:

  • Historical review of scientific literature on parathyroid hormone (PTH).
  • Analysis of key milestones in understanding calcium and bone physiology.
  • Examination of research leading to the pharmacological use of PTH.

Main Results:

  • PTH's function in calcium physiology was clarified by 1925.
  • The structure of PTH and its receptor (PTHR1) were elucidated.
  • Pharmacological administration of PTH was found to build bone, impacting osteoporosis therapy.

Conclusions:

  • PTH research has progressed through distinct phases, significantly advancing bone and calcium biology.
  • The discovery of PTH's bone-building potential offers a paradigm shift in osteoporosis treatment.
  • Further research into PTH continues to open new therapeutic avenues.
