Chromogranins are acidic secretory glycoproteins with a widespread but specific distribution in neuroendocrine tissues. The chromogranin family is heterogenous, consisting of propeptides such as chromogranin-A, chromogranin-B and secretogranin II, which can either elicit an effect themselves, or serve as precursors to a large number of peptides, which are biologically more active.

Chromogranin A is also elevated in 80% to 90% of patients with symptomatic foregut and midgut tumors. -Urine serotonin is in most circumstances the least likely marker to be elevated. The exception is tumors (usually foregut tumors) that produce predominately 5-HTP, rather than serotonin, and also secrete little, if any, chromogranin A.

CRP is an acute phase reactant, which can be used as a test for inflammatory diseases, infections, and neoplastic diseases. Progressive increases correlate with increases of inflammation/injury. CRP is a more sensitive, rapidly responding indicator than ESR. CRP may be used to detect early postoperative wound infection and to follow therapeutic ... Chromogranin-A ( Cga) or parathyroid secretory protein 1 is encoded in the human by the gene CHGA. Cga is a member of the granin family of neuroendocrine secretory proteins. As such, it is located in secretory vesicles of neurons and endocrine cells such as islet beta cell secretory granules in the pancreas. [5] Serum chromogranin A (CgA), a hydrophilic, acidic single-chain glycoprotein (439 amino acids), also known as parathyroid secretory protein 1, is the best studied member of the larger chromogranin family and serves as a marker for the identification and staging of neuroendocrine tumors (NETs) (10, 11). CgA acts as a precursor of different ...Chromogranin A is a useful diagnostic biomarker for neuroendocrine tumors such as carcinoid tumors, pheochromocytoma and neuroblastoma.

Carcinoid tumors, which typically form in the lungs or gastrointestinal tract are often associated with increased CGA ...Chromogranin A (CgA), which is an intrinsically disordered protein that belongs to the granin family, was first discovered in the bovine adrenal medulla, and later identified in various organs. Under certain physiological conditions, CgA is cleaved into functionally diverse peptides, such as vasostatin-1, pancreastatin, and catestatin. In this review, we first describe the historical and ...
