Background
Chromogranin A (CgA) belongs to chromogranin family and regulates neuroendocrine granule storage as well as hormone processing and secretion. CgA is packaged within secretory vesicles of neuroendocrine cells and co-released together with hormones. Proteolytic cleavage of CgA yields multiple bioactive peptides modulating hormone release, vascular homeostasis and inflammatory responses. CgA is abundant in pituitary, adrenal medulla and gastrointestinal neuroendocrine cells. It is highly expressed in neuroendocrine tumors and represents a critical diagnostic biomarker. Circulating CgA also serves as auxiliary serological indicator for certain neuroendocrine neoplasms.
