Parathyroid hormone-related protein (PTHrP) is a proteinaceous hormone and a member of the parathyroid hormone family secreted by mesenchymal stem cells. It is occasionally secreted by cancer cells (for example, breast cancer , certain types of lung cancer including squamous-cell lung carcinoma ).
The parathyroid glands are quite easily recognizable from the thyroid as they have densely packed cells, in contrast with the follicular structure of the thyroid. [6] Two unique types of cells are present in the parathyroid gland: Chief cells, which synthesize and release parathyroid hormone. These cells are small, and appear dark when loaded ...
Teriparatide, sold under the brand name Forteo, is a form of parathyroid hormone (PTH) consisting of the first 34 amino acids, which is the bioactive portion of the hormone. [13] It is an effective anabolic (promoting bone formation) agent [ 15 ] used in the treatment of some forms of osteoporosis .
Parathyroid hormone (PTH) is a polypeptidic hormone primarily involved in calcium metabolism. The parathyroid hormone-related protein (PTH-rP) is a related protein with predominantly paracrine function and possibly an endocrine role in lactation, as PTHrP has been found to be secreted by mammary glands into the circulation and increase bone ...
Calcitriol is a hormone and the active form of vitamin D, normally made in the kidney. [8] [9] [10] It is also known as 1,25-dihydroxycholecalciferol.It binds to and activates the vitamin D receptor in the nucleus of the cell, which then increases the expression of many genes. [11]
Parathyroid chief cells (also called parathyroid principal cells or simply parathyroid cells) are the primary cell type of the parathyroid gland. They produce and secrete parathyroid hormone (PTH) in response to low calcium levels. PTH plays an important role in regulating blood calcium levels by raising the amount of calcium in the blood. [1]
Calcitonin is a polypeptide hormone of 32 amino acids, with a molecular weight of 3454.93 daltons. Its structure comprises a single alpha helix. [40] Alternative splicing of the gene coding for calcitonin produces a distantly related peptide of 37 amino acids, called calcitonin gene-related peptide (CGRP), beta type. [41]
