Application

Chromogranin A (parathyroid secretory protein 1) is a precursor of the vasostatin, pancreastatin, catestatin, parastatin, chromostatin, GE-25 and WE-14. WE 14 is used to search for its as yet undefined physiological roles.

Catestatin (bovine CgA(344-364)) is a cationic peptide, which besides reducing catecholamine secretion from chromaffin cells in vitro also acts a potent vasodilator in the rat in vivo. The alleged histamine releasing effect of catestatin was tested in vitro in rat

WE-14 is generated in subpopulations of chromogranin A immunopositive endocrine cells and neurons including those innervating the anterior uvea. This study investigated WE-14 in intact sclero-limbo-corneal tissue from embryonic (E17), neonatal (N0-N16), and adult mice using immunocytochemistry and confocal scanning

The neuropeptide WE-14 is derived from the posttranslational processing of chromogranin A (CgA). While CgA is expressed in a preponderance of neuroendocrine cells, WE-14 is generated in a distinct subpopulation of CgA-immunopositive cells, most notably in the adrenal, pituitary, and

Immunohistochemical analysis of the male and female rat adenohypophysis revealed that chromogranin A (CgA), beta-granin and WE-14 immunostaining was localised to follicle stimulating hormone (FSH) producing cells, while luteinizing hormone (LH) producing cells exhibited chromogranin A and beta-granin immunostaining.
