Chromogranin A. Storage and release in hypertension.
The chromogranins/secretogranins are a family of acidic, soluble proteins with widespread neuroendocrine distribution in secretory vesicles. Although the precise function of the chromogranins remains elusive, knowledge of their structure, distribution, and potential intracellular and extracellular roles, especially that of chromogranin A, has greatly expanded during recent years. Chromogranin A...
متن کاملChromogranin A in Physiology and Oncology ( chromogranin / neuroendocrine tumours / cleavage fragments / extracellular functions / intracellular functions / tumour marker )
Chromogranin A (CgA) is a hydrophilic acidic one-chain peptide containing 439 amino acids, preceded by NH 2 -terminal 18-amino-acid signal peptide; the complete pre-chromogranin A molecule thus encompasses 457 amino acids. It is a member of the chromogranin family that comprises several proteins. The CgA gene is a single-copy gene localized in the locus 14q32. Chromogranin A is produced by endo...

"There appears to be a direct correlation between tumor burden and serum CgA levels. Rising serum levels of CgA can predeed radiographic evidence of recurrence. . . . .Using serum CgA level above 30 U/ml, one is able to discriminate between disease free patients and those with recurrent metastatic disease with a sensitivity of 92% and specificity of 96%. This is superior to measuring urinary 5-...
متن کامل[Chromogranin A and neuroendocrine tumors].
Chromogranin A (CgA) is the most abundant granin in gastroenteropancreatic neuroendocrine tumors (GEP-NETs). As a tumor marker is moderately sensitive and nonspecific. Despite the limitations of testing methods, which require careful interpretation, especially in the case of gastrinomas, patients treated with somatostatin analogues, and poorly differentiated tumors, it is the best tumor marker ...
متن کاملChromogranin A in heart failure.
Since the initial demonstration of increased circulating norepinephrine in patients with chronic heart failure, a large number of investigations on neuroendocrine activation in heart failure have followed. It is now clear that persistent activation of neuroendocrine systems, notably the adrenergic system and the renin–angiotensin system is maladaptive in heart failure (reviewed in). In this iss...
