If, in the course of monitoring a patient, the assay method used for determining Chromogranin A levels is changed, additional tests should be carried out toAbstract. Background: Chromogranin A (CgA) is a biomarker for neuroendocrine tumors (NETs). The aims of this study were to evaluate differences in measurement between the ThermoFisher Brahms CgA Kryptor assay and the CisBio assay and to investigate the influence of patient covariates. Temperature stability of CgA using …Product Description. This antibody cocktail recognizes a protein of 68-75 kDa, identified as Chromogranin A antibody. The combination of LK2H10 and PHE5 is specifically designed for sensitive detection of Chromogranin A in formalin-fixed, paraffin-embedded (FFPE) tissues. Chromogranin A is present in neuroendocrine cells throughout the body.Chromogranin A (CgA) is a protein present in neuroendocrine vesicles. Small cell lung cancer (SCLC) is considered a neuroendocrine tumour. It is possible to demonstrate CgA expression in SCLC by immunohistochemical methods. Since CgA is released to the circulation it might also work as a clinical tumour marker.Chromogranin A (CgA) is a prohormone initially extracted from the adrenal medulla, however, increased quantities of CgA are secreted by a wide array of human tissues in the course of a variety of disorders. This protein exhibits a number of interesting endocrine and non-endocrine functions. Here we briefly review the possible involvements of ...

Chromogranin A (CgA) is an 86 kDa protein that is the major member of the granin family of acidic secretory glycoproteins located in neuroendocrine cells. CgA is believed to play a role in targeting peptide hormones and neurotransmitters to granules of the regulated pathways and inhibit hormone and neurotransmitter release. Also, the widespread ...

Chromogranin A is a soluble protein that is stored and released with catecholamines from their secretory vesicles. Its measurement is a probe of exocytotic sympathoadrenal activity, and in plasma it may also be a useful tool in the diagnosis of peptide producing endocrine neoplasms. Because we have found that chromogranin A is elevated in ...

Additional Information. Histamine is synthesized from the amino acid L-histidine through the action of the enzyme histidine decarboxylase. 1 This small molecule is primarily produced by mast cells and basophils. These cells are morphologically characterized by numerous, electron dense cytoplasmic granules, which contain histamine and other ...• Histamine (LabCorp; plasma) • Tryptase (LabCorp; serum) • Prostaglandin D2 (PGD2) (Quest; 24-hour urine) • Chromogranin A (Quest; serum) Prior to collecting samples for these tests, a provocation is generally recommended whereby the patient consumes foods known to be high in histamine, resulting in the triggering ofChromogranin A, like NSE, is found in all identifiable endocrine cells of the gut ( Facer et al., 1985) ( Fig. 13) and can be detected in human fetal gut before peptides ( Fig. 14 ). Its concentration within a cell fluctuates with the granule content. Unlike NSE, which is often only weakly immunostained in the large bowel, chromogranin A shows ...Chromogranin A is a member of the granin glycoprotein family that is expressed by the endocrine and neuroendocrine cells of different organs. Intracellularly, chromogranin A contributes to the regulation of secretion and gives several cleavage products after secretion. Some of its cleavage products modify the hormone functions in autocrine and ...

Chromogranin A, due to its primary expression throughout the neuroendocrine system, is a widely accepted biomarker for the assessment of neuro-endocrine tumors. It has been traditionally used in the management of patients with tumors of gastro-enteropancreatic origin. Lately, it has also been implicated in various conditions …

Here we show how pro-hormone Chromogranin A (CgA), produced by the enteroendocrine cells, and Catestatin (CST: hCgA 352-372 ), the most abundant CgA-derived proteolytic peptide, affect the gut barrier. Methods: Colon tissues from region-specific CST-knockout (CST-KO) mice, CgA-knockout (CgA-KO) and WT mice were analysed by immunohistochemistry ...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 granule ...Ferritin is found in virtually all cells of the body and serves as the cellular storage repository for iron. 2,3 Ferritin is a macromolecule with an average molecular weight of near 440 kD that varies depending on the iron content. Ferritin consists of a protein shell (apoferritin) of 24 subunits surrounding an iron core consisting of up to 4000 ferric iron ions.Chromogranin A (CgA) is a non-specific biomarker excreted by neuroendocrine tumor (NET) cells. Elevation of circulating CgA level can be detected in gastroenteropancreatic (GEP)-NET patients and has been shown to correlate with tumor burden. The prognostic and predictive roles of CgA level and the change of CgA level …Small bowel was the primary tumor site in 44 patients (57%), and 49 patients had metastasis to the liver (64%). Sensitivity and specificity of serum pancreastatin was 85.7% and 66.7%, respectively, which compared with 61.5% and 43.8% for chromogranin A, in identifying liver metastasis in patients with primary tumors of the small bowel.

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 ...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.
