靶點詳情

  • 功能：
    Liver-produced hormone that constitutes the main circulating regulator of iron absorption and distribution across tissues. Acts by promoting endocytosis and degradation of ferroportin/SLC40A1, leading to the retention of iron in iron-exporting cells and decreased flow of iron into plasma. Controls the major flows of iron into plasma: absorption of dietary iron in the intestine, recycling of iron by macrophages, which phagocytose old erythrocytes and other cells, and mobilization of stored iron from hepatocytes.; Has strong antimicrobial activity against E.coli ML35P N.cinerea and weaker against S.epidermidis, S.aureus and group b streptococcus bacteria. Active against the fungus C.albicans. No activity against P.aeruginosa.

    8. Data suggest that magnitude of up-regulation of serum hepcidin levels in response to acute exercise in adults is dependent on pre-exercise iron nutritional status (ferritin levels) and on circulating pro-inflammatory cytokines (prominently interleukin-6). [REVIEW] PMID: 29443922
    9. The present study provides new evidence that ASP decreases hepcidin expression, which can reduce iron burden and inhibit tumor proliferation. These findings might aid ASP developed as a potential candidate for cancer treatment in patients with iron overload. PMID: 29843136

    13. Increasing adiposity in the pediatric population is associated with increasing IL-6, which stimulates hepcidin synthesis, leading to functional iron deficiency due to inhibition of iron absorption and mobilization from iron stores. PMID: 28604755
    14. Suggest that pentoxifylline may be a clinically and biologically meaningful modulator of hepcidin-25 in dialysis of patients with ESA-hyporesponsive anaemia. PMID: 27171136
    15. Among low birth weight infants, gestational age, IL-6, erythropoietin, and soluble transferrin receptor were associated with Hep25 levels. Therefore, prematurity, inflammation, hypoxia, and erythropoietic activity may be important perinatal factors that affect hepcidin levels. PMID: 28601871
    16. genetic association studies in cohort of infants in Spain: Data suggest that serum hepcidin levels increase in infants during first year of life and are positively associated with iron status only in infants with wild-type HFE gene (not in infants with genetic polymorphisms C282Y, H63D, and S65C). (HFE, homeostatic iron regulator) PMID: 29404719
    17. Data suggest that circulating hepcidin levels (a biomarker for iron-deficiency anemia) may be regulated by dietary factors other than iron; here, one-time high-dose vitamin D3 reduces plasma hepcidin levels in adults one week post-dosing, without changes in plasma pro-inflammatory cytokine or ferritin concentrations.

    19. Data suggest that hematologic parameters in children consuming lacto-ovo vegetarian diets are comparable with those of control children, but ferritin levels are lower; inclusion of novel serum biomarkers, soluble transferrin receptor and hepcidin, in nutritional assessment can better detect subclinical iron deficiency in children following vegetarian diet. This study was conducted in Poland with children ages 4.5-9 years. PMID: 28342014

    22. increased intracellular iron content in recombinant-TfR1 HepG2 cells did not increase hepcidin responses compared to wild-type cells, resembling hemochromatosis PMID: 27667164

    25. Of the non-HFE forms of iron overload, TFR2-, HFE2-, and HAMP-related forms are predicted to be rare, with pathogenic allele frequencies in the range of 0.00007 to 0.0005.

    26. Data (including data from studies using knockout mice) suggest that MT2/TMPRSS6 suppresses hepcidin expression in hepatocytes independently of HJV; MT2/TMPRSS6 cleaves ALK2, ALK3, ACTRIIA, BMPR2, HFE, and, to a lesser extent, HJV and TFR2; thus, MT2/TMPRSS6 suppresses hepcidin expression by cleaving multiple components of the hepcidin induction pathway. (MT2/TMPRSS6 = matriptase-2; HJV = hemojuvelin) PMID: 28924039
    27. two unrelated hepatocellular carcinoma patients bore the HAMP:c.-153C>T mutation at the heterozygous state, which is associated with increased risk of iron overload and severe hemochromatosis PMID: 26474245

CD14+ monocytes from individuals with the rs10421768 GG genotype secreted significantly less hepcidin in response to M. tuberculosis lipoarabinomannan compared with cells from individuals with either the AA or AG genotypes.

    37. Main pathways of systemic and genetic regulation of hepcidin, as well as its influence on the disorders related to iron metabolism. Review. PMID: 28514781
    38. Data suggest hepcidin is the master regulator of systemic iron homeostasis; hepcidin levels are suppressed when erythropoiesis is stimulated; the erythroid-derived hormone erythroferrone appears to be a convincing candidate for link between increased erythropoiesis and hepcidin suppression. [REVIEW] PMID: 27146013
    39. Data suggest that proinflammatory cytokine interleukin-1beta (IL1B) up-regulates hepcidin expression in hepatocytes; inflammation induces IL1B production in Kupffer cells and hepatocytes; IL1B up-regulates CEBPD (CCAAT/enhancer binding protein delta) expression in hepatocytes; up-regulation of CEBPD expression up-regulates hepcidin transcription. PMID: 28438835
    40. modification of HS structure mediated by heparanase overexpression affects hepcidin expression and iron homeostasis PMID: 27711215
    41. Serum hepcidin levels increased in premenopausal women participating in brisk walking exercises. PMID: 28361576

    46. The data of in vitro and in vivo research evidenced on involvement of Hepc in formation of breast cancer cells malignant phenotype and their resistance to doxorubicin. PMID: 27356575
    47. Hepcidin was a more influential determinant of iron stores than blood loss and dietary factors combined, and increased hepcidin diminished the positive association between iron intake and iron stores. PMID: 27598194
    48. These results suggest that the ingestion of a high (compared to low) CHO diet over a seven-day training period is ineffective in attenuating post-exercise IL-6 and hepcidin responses. Such results may be due to the modest training load, the increased protein intake in the low-CHO trial, and a 48 h recovery period prior to sample collection on day 7, allowing a full recovery of muscle glycogen status between exercise sessi PMID: 27379793
    49. The NGAL/hepcidin ratio is more strongly associated with severe of acute kidney injury than the single biomarkers alone PMID: 25479470
