Calcitonin gene-related peptide stimulates proliferation of human endothelial cells.

Calcitonin gene-related peptide stimulates proliferation of human endothelial cells.

The effects of the vasoactive perivascular neuropeptides calcitonin gene-related peptide (CGRP), neurokinin A (NKA), neuropeptide Y (NPY), and vasoactive intestinal polypeptide (VIP) on proliferation of cultured human umbilical vein endothelial cells (HUVECs) were investigated. CGRP was shown to increase both cell number and DNA synthesis, whereas NKA, NPY, and VIP were ineffective. 125I-labele...

Calcitonin gene-related peptide stimulates proliferation of alveolar epithelial cells

BACKGROUND Alveolar epithelial cells are known as progenitor cells for the restoration from the damage in the lung. Calcitonin gene-related peptide (CGRP) has been reported to play an important role in the proliferation of various types of epithelial and endothelial cells. We investigated the effects of CGRP on the proliferation of alveolar epithelial cells in vitro and in vivo. METHODS A549 ...

Calcitonin gene-related peptide promotes Schwann cell proliferation

Schwann cells in culture divide in response to defined mitogens such as PDGF and glial growth factor (GGF), but proliferation is greatly enhanced if agents such as forskolin, which increases Schwann cell intracellular cAMP, are added at the same time as PDGF or GGF (Davis, J. B., and P. Stroobant. 1990. J. Cell Biol. 110:1353-1360). The effect of forskolin is probably due to an increase in numb...

Calcitonin Gene-Related Peptide (CGRP)

Calcitonin gene-related peptide (CGRP) is a 37 amino acid vasoactive neuropeptide that is widely distributed in central and peripheral nervous systems in mammals. CGRP was discovered in 1982 by molecular cloning of calcitonin (CT) gene. CGRP-specific mRNA appears to predominate in the hypothalamus while CT mRNA predominates in the thyroid. CGRP has an amphiphilic α-helical secondary structure i...
