靶點詳情

  • 功能：
    Strongly inhibits glucose induced insulin release from the pancreas.; Inhibits catecholamine release from chromaffin cells and noradrenergic neurons by acting as a non-competitive nicotinic cholinergic antagonist. Displays antibacterial activity against Gram-positive bacteria S.aureus and M.luteus, and Gram-negative bacteria E.coli and P.aeruginosa. Can induce mast cell migration, degranulation and production of cytokines and chemokines. Acts as a potent scavenger of free radicals in vitro. May play a role in the regulation of cardiac function and blood pressure.; Regulates granule biogenesis in endocrine cells by up-regulating the transcription of protease nexin 1 (SERPINE2) via a cAMP-PKA-SP1 pathway. This leads to inhibition of granule protein degradation in the Golgi complex which in turn promotes granule formation.
  • 基因功能參考文獻：
    1. 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. PMID: 29858590
    2. 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. PMID: 28397784
    3. CgA and NSE are clinically valuable tumor markers in neuroblastoma and they merit prospective clinical evaluations as such. PMID: 29737901
    4. Vasostatin-1 is stably overexpressed in serum of patients with ileal and pancreatic neuroendocrine neoplasms. PMID: 29723285
    5. 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. PMID: 28406540
    6. cardiac atria express but do not secrete CgA into circulation in patients with atrial disease PMID: 28685598
    7. 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. PMID: 27683038
    8. 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. PMID: 27203389
    9. The authors show that CHGA-415 T/C polymorphism is an independent risk factor of poor prognosis in critically ill patients PMID: 28254729
    10. 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. PMID: 27771336
    11. Full-length CgA is an independent indicator of atherosclerotic plaques in carotid artery stenosis. PMID: 28190616
    12. 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. PMID: 28095720
    13. Compared with chromogranin A, chromogranin B may be more useful during proton pump inhibitor treatment and can detect tumors without liver metastases. PMID: 28334992
    14. 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. PMID: 26750135
    15. 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. PMID: 28886122
    16. Combined plasma CgA concentrations and World Health Organization grading may assist in better stratification of PNET patients in terms of the risk of recurrence. PMID: 28043759
    17. 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. PMID: 28870943
    18. 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. (CHGA = chromogranin A; c-Rel = c-Rel proto-oncogene protein) PMID: 28667172

    23. 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. PMID: 28209766
    24. Data suggest pancreastatin, a 49 residue post-translational fragment of chromogranin A, as a routinely tested biomarker in neuroendocrine tumors (NETs) and in particular small bowel NET. PMID: 26684860
    25. Data indicate that measurement of chromogranin A (CgA) alone is sufficient in the management of patients with neuroendocrine tumours (NETs) and that routine additional measurement of chromogranin B (CgB) provides little added value. PMID: 26608723
    26. Data show that chrysin suppressed cell proliferation and reducing expression of achaete-scute complex-like 1 (ASCL1) and the neuroendocrine biomarker chromogranin A (CgA). PMID: 26403073
    27. In a Japanese population, the Ser-364 allele was associated with elevated systolic blood pressure and pulse pressure, consistent with increased arterial stiffness. PMID: 26211667
    28. ChrA levels were not effective in predicting outcomes or detecting recurrences of Merkel cell carcinoma. PMID: 26299616
    29. Decreased CSF levels of chromogranin A were found in Parkinson disease patients with orthostatic hypotension. PMID: 26359267
    30. In both mice and men the Gly364Ser polymorphism conferred metabolic traits such as elevated HDL and lowered norepinephrine levels; it was associated with superior baroreflex function and therefore better response to stress. PMID: 26556564
    31. In patients with resected pancreatic neuroendocrine tumors, an elevated preoperative CgA level was negatively associated with disease-free survival and overall survival. PMID: 26850182
    32. In astrocytes from multiple sclerosis white matter lesions the expression of chromogranin A is increased. PMID: 26683597
    33. Receiver operating characteristic analyses showed that ChgA autoantibodies are valuable in the predictive diagnosis of non-small cell lung cancer (NSCLC), suggesting that serum autoantibodies to ChgA-derived peptides are promising novel markers of NSCLC PMID: 26186986
    34. Diagnostic value of circulating chromogranin a for neuroendocrine tumors PMID: 25894842
    35. Data indicate that ADP-ribosylation factor 1 (Arf1) colocalizes with chromogranin A and regulates secretion of insulin like growth factor 1 (IGF-1) and is required for anchorage dependent growth. PMID: 25754106

    37. The CHGA 3'-UTR C+87T disrupts an miR-107 motif, with differential effects on CHGA expression, and a cis:trans (mRNA:miR) interaction regulates the association of CHGA with BP and hypertensive nephropathy. PMID: 25392232
    38. Chromogranin A measurements are significantly assay-dependent and caution should be applied in the interpretation of CgA measurement for assessment of neuroendocrine tumor status. PMID: 25532001
    39. Chromogranin A (10-19) and chromogranin A (43-52) were identified as antigens for autoreactive CD8(+) T cells in Type 1 diabetes patients. PMID: 25958206
