Chromogranin a labcorp.

Nonhormonal secretory products, such as chromogranin A, pancreastatin, and pancreatic polypeptide are often produced by both functional and nonfunctional NETs, and can serve as circulating serum tumor markers . In addition to these hormonal and nonhormonal peptide markers, novel circulating RNA-based tests have been developed that are ...LabCorp is a trusted name in the healthcare industry, known for its commitment to providing quality laboratory services.

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]Chromogranin A. The most important marker, chromogranin A (CgA), is a constitutive secretory product of most neuroendocrine tumors. Depending on the extent of the disease, plasma CgA is elevated in > 60% of patients. CgA levels may correlate with tumor volumes, but care should be taken in measuring CgA and interpreting the results.Chromogranin A (CGA), 48-75 kDa, 439 amino acids, is the diagnostically most important of these glycoproteins, and probably the major target of the argyrophilic Grimelius staining reaction. Post-translational processing of CGA gives rise to fragments with biologic activities such as autocrine and paracrine functions. A number of CGA fragments ...

Chromogranin A (CgA) is a 49-kDa acidic glycoprotein that belongs to the granin family, a principal component of dense-core granules in neuroendocrine cells. Its expression generally correlates with the number of dense-core granules in neuroendocrine cells. CgA and hormones are co-secreted from neuroendocrine cells during the secretory …

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 ...
