ABSTRACT Chronic inflammatory diseases are often associated with anemia. In such conditions, anemia is generally treated with erythropoiesis stimulating agents (ESAs) which are associated with potentially hazardous side effects and poor outcomes. Suboptimal erythropoiesis in chronic inflammation is believed to be caused by elevated hepcidin levels, which causes blockade of iron in tissue stores. In the current work using rodent models of inflammation, an orally available small molecule prolyl… Expand

Prolyl hydroxylase inhibitor desidustat protects against acute and chronic kidney injury by reducing inflammatory cytokines and oxidative stress
TLDR
Desidustat treatment reduced the renal fibrosis and inflammation along with a reduction in anemia in preclinical models of kidney injury, which may translate to protective effects in CKD patients. Expand
Black pepper prevents anemia of inflammation by inhibiting hepcidin over-expression through BMP6-SMAD1/ IL6-STAT3 signaling pathway.
TLDR
Black pepper is suggested as a therapeutic candidate for the treatment of anemia of inflammation after in vitro and in vivo studies found BPME and piperine to be most effective in downregulating transcription of hepcidin gene. Expand
HIF Prolyl Hydroxylase Inhibitors for COVID-19 Treatment: Pros and Cons
TLDR
HIF prolyl hydroxylase inhibitors may serve as a promising treatment of COVID-19 complications, but they are unlikely to aid in the prevention of the initial stages of infection. Expand

Hepcidin‐dependent and hepcidin‐independent regulation of erythropoiesis in a mouse model of anemia of chronic inflammation
TLDR
Differences in erythrocyte parameters suggest anemia in many inflammatory states may not be fully explained by hepcidin‐mediated iron sequestration, and chronic anemia associated with inflammation may benefit from interventions protecting ery Throcyte number in addition to anti‐hePCidin interventions aimed at enhancing iron availability. Expand
Novel erythropoiesis stimulating protein (darbepoetin alfa) alleviates anemia associated with chronic inflammatory disease in a rodent model.
TLDR
Darbepoetin alfa treatment reversed ACD in this rodent model by increasing RBC production and RBC hemoglobinization while reducing siderosis and hypoferremia. Expand
Hepcidin regulation in the anemia of inflammation
TLDR
Recent studies confirm an important role for the hepcidin–ferroportin axis in the development of anemia of inflammation, but also highlight the diverse and complex pathogenesis of this disorder depending on the underlying disease. Expand
Pharmacological Characterization of ZYAN1, a Novel Prolyl Hydroxylase Inhibitor for the Treatment of Anemia.
TLDR
The efficacy of ZYAN1 in disease models of different etiologies suggests that it will be useful in treating wide spectrum of anemia patients and hematinic potential by combined effects on EPO release and efficient iron utilization is demonstrated. Expand
Erythropoietin's inhibiting impact on hepcidin expression occurs indirectly.
TLDR
It is suggested that the role of Epo is to stimulate the synthesis of the erythroid regulator ERFE in erythroblasts, which ultimately downregulates hepcidin. Expand
Prolyl Hydroxylase Inhibitors: A Breakthrough in the Therapy of Anemia Associated with Chronic Diseases.
TLDR
The role of PHD inhibitors in the treatment of anemia associated with chronic diseases is discussed and many orally active PHD inhibitor like roxadUSTat, molidustat, vadadustats, and desidustat are in late phase clinical trials. Expand

TLDR
Regulation of hepcidin and iron availability for erythropoiesis has revealed unexpected pathways and much complexity and the renaissance of the study of iron regulation continues to reward researchers with interesting biology and potential therapeutic targets. Expand
Hypoxia-inducible factor regulates hepcidin via erythropoietin-induced erythropoiesis.
TLDR
In vivo evidence is provided that Hamp1 suppression by the HIF pathway occurs indirectly through stimulation of EPO-induced erythropoiesis, the molecular basis of hypoxia/HIF-mediated hepcidin suppression in the liver remains unclear. Expand
The gene encoding the iron regulatory peptide hepcidin is regulated by anemia, hypoxia, and inflammation.
TLDR
Modifications of hepcidin gene expression suggest a key role for hepciridin in iron homeostasis under various pathophysiological conditions, which may support the pharmaceutical use of hePCidin agonists and antagonists in various ironHomeostasis disorders. Expand
Inhibition of prolyl hydroxylases increases erythropoietin production in ESRD.
TLDR
The data demonstrate that pharmacologic manipulation of the HIF system can stimulate endogenous EPO production and indicate that deranged oxygen sensing--not a loss of EPOProduction capacity--causes renal anemia. Expand
