Study indicates that chga may play an important role in nervous system development during the early embryonic stages.
Elevated CHGA expression resulted in underlying bioenergetic dysfunction in ATP production despite higher mitochondrial mass. The outcome was unregulated negative feedback of LDCV exocytosis and secretion, resulting in elevated levels of circulating catecholamine and consequently the hypertensive phenotype.
Chromogranin-A and its role in the pathogenesis of diabetes mellitus is reviewed.
Study using live-cell imaging at single vesicle resolution revealed a normal number of fusion events upon bursts of action potentials in CgA/B-/- neurons. Data indicate that the two chromogranins are dispensable for cargo sorting in the regulated secretory pathway and dense-core vesicle in mouse hippocampal neurons.
Data suggest that hybrid insulin peptides (HIPs), formed in insulin-secreting-cells by fusion of insulin C-peptide fragments to peptide fragments of chromogranin A or islet amyloid polypeptide, and reactivity of CD4+-T-lymphocytes to HIPs may act as biomarkers of autoimmunity in type 1 diabetes.

Increased myocardial CgA glycosylation and impaired CgA processing to catestatin in heart failure be considered detrimental because CST reduces diastolic Ca2+ leak via direct CaMKIIdelta inhibition.
performance of CgA-deficient Chga-KO mice in treadmill exercise was impaired. CgA deficiency renders the muscle energy deficient, impairs performance in treadmill exercise and prevents regeneration after exercise-induced tissue damage.

Chromogranin A contributes to a highly efficient system that directly mediates monoamine accumulation and exocytosis in large dense core secretory vesicles.
Data indicate that circulating chromogranin A (CgA) has a better overall accuracy in the follow-up setting [Review and Meta-analysis].
Elevated serum CGA was negatively associated with overall survival in men with metastatic castrate resistant prostate cancer. Serum CGA represents a prognostic biomarker that may complement circulating tumor cells enumeration.
Patients with higher catestatin levels developed worse ventricular function during the follow-up period. Single-point catestatin was effective to predict LVEDD change. And concurrently increasing catestatin and NT-proBNP levels predicted the highest risk of LV remodeling. This study suggests an important prognostic information of catestatin on LV remodeling.
CgA and NSE are clinically valuable tumor markers in neuroblastoma and they merit prospective clinical evaluations as such.
Vasostatin-1 is stably overexpressed in serum of patients with ileal and pancreatic neuroendocrine neoplasms.
Results suggest that severe atopic dermatitis is associated with higher stress levels. Simple salivary CgA measurements may be useful as an objective assessment of patient stress.
cardiac atria express but do not secrete CgA into circulation in patients with atrial disease
These results suggest that circulating full-length CgA is an important inhibitor of angiogenesis and tumor growth, and that cleavage of its C-terminal region markedly reduces its activity. Pathophysiological changes in CgA blood levels and/or its fragmentation might regulate disease progression in cancer patients.
Results show that chronic lymphocytic leukemia (CLL) patients had increased plasma levels of chromogranin A (CgA), compared to normal subjects, particularly those >70-year-old or those treated with proton pump inhibitors.
The authors show that CHGA-415 T/C polymorphism is an independent risk factor of poor prognosis in critically ill patients
Concurrent increases in plasma BNP (B-type natriuretic peptide) and CST levels predicted the highest risk for both all-cause and cardiac deaths in chronic heart failure patients.
Full-length CgA is an independent indicator of atherosclerotic plaques in carotid artery stenosis.
Even a single baseline measurement of CgA can be useful in establishing prognosis in this group, if this parameter exceeds its upper normal limit more than tenfold.
Compared with chromogranin A, chromogranin B may be more useful during proton pump inhibitor treatment and can detect tumors without liver metastases.
Salivary impairments and high levels of CHGA are associated with T2DM patients. In addition, CGHA polymorphisms might be associated with salivary gland hypofunction and higher salivary CHGA production in T2DM patients. This could be a significant insight to establish a role for salivary CHGA as a potential clinical biomarker to T2DM.
we could provide evidence that established stress-related biomarkers ET-1, MCP-1, CGA were differentially regulated among patients with AF compared to healthy controls.
Combined plasma CgA concentrations and World Health Organization grading may assist in better stratification of PNET patients in terms of the risk of recurrence.
Metastatic castration-resistant prostate cancer patients with an early high CGA rise may demonstrate a subgroup with poor outcome due to underlying small cell/neuroendocrine cell transformation.
genetic association studies in population in India: Data suggest that common polymorphisms (SNPs) in CHGA promoter are associated with cardiometabolic disorders; c-Rel has a role in activating CHGA promoter haplotype 2 (variant T alleles at -1018 and -57 bp) under basal and pathophysiological conditions.

Cateslytin adopts a dominant beta-sheet character upon interaction with negatively charged membranes, whereas it is essentially unstructured in water as are most short linear antimicrobial peptides.
The protein encoded by this gene is a member of the chromogranin/secretogranin family of neuroendocrine secretory proteins. It is found in secretory vesicles of neurons and endocrine cells. This gene product is a precursor to three biologically active peptides\; vasostatin, pancreastatin, and parastatin. These peptides act as autocrine or paracrine negative modulators of the neuroendocrine system. Other peptides, including chromostatin, beta-granin, WE-14 and GE-25, are also derived from the full-length protein. However, biological activities for these molecules have not been shown.
