The protective effect of red cabbage extract (RCE) was evaluated in rats with streptozotocin-induced diabetes, assessing a probable role of this extract in the prevention of erythrocyte impairments associated with a high risk of vascular complications in diabetes. RCE was analyzed by ultrahigh performance liquid chromatography and mass spectrometry, and 11 anthocyanins, 3 hydroxybenzoic acids and 9 hydroxycinnamic acids were identified. Type 1 diabetes was induced by streptozotocin (60 mg kg-1 ) in Wistar male rats (n = 8 per group)...

The prevalence of Iron Deficiency Anemia (IDA) is predominant in women and children especially in developing countries. The disorder affects cognitive functions and physical activity. While oral iron supplementation and parenteral therapy remains the preferred choice of treatment, gastric side effects and risk of iron overload decreases adherence to therapy. Transdermal route is an established approach which circumvents the side-effects associated with conventional therapy. In this project, an attempt was made to investigate the use of rapidly dissolving microneedles loaded with Ferric pyrophosphate (FPP) as a potential therapeutic approach for management of IDA...

BACKGROUND: Epoetin beta pegol (continuous erythropoietin receptor activator; C.E.R.A.) is currently widely used for the treatment of anemia associated with chronic kidney disease (CKD). Therapeutic control of anemia is assessed by monitoring haemoglobin (Hb) levels. However, certain qualitative aspects of erythrocytes are also impaired in CKD, including loss of deformability and shortened life-span. Therefore, monitoring Hb alone could potentially fail to reveal pathological changes in erythrocytes...

Inhibition of hypoxia inducible factor prolyl hydroxylase (PHD) represents a promising strategy for the discovery of a next generation treatment for renal anemia. We identified several 5,6-fused ring systems as novel scaffolds of the PHD inhibitor on the basis of pharmacophore analysis. In particular, triazolopyridine derivatives showed potent PHD2 inhibitory activities. Examination of the predominance of the triazolopyridines in potency by electrostatic calculations suggested favorable π-π stacking interactions with Tyr310...

Arginine vasopressin (AVP) made by hypothalamic neurons is released into the circulation to stimulate water resorption by the kidneys and restore water balance after blood loss. Patients who lack this antidiuretic hormone suffer from central diabetes insipidus. We observed that many of these patients were anemic and asked whether AVP might play a role in red blood cell (RBC) production. We found that all three AVP receptors are expressed in human and mouse hematopoietic stem and progenitor cells. The AVPR1B appears to play the most important role in regulating erythropoiesis in both human and mouse cells...

Lead-induced hepatotoxicity is characterized by an extensive oxidative stress. Grape seed procyanidin extract (GSPE) possesses abundant biological activities. Herein, we investigated the protective role of GSPE against lead-induced liver injury and determined the potential molecular mechanisms. In vivo, rats were treated with/without lead acetate (PbAc) (0.05%, w/v) in the presence/absence of GSPE (200 mg/kg). In vitro, hepatocytes were pretreated with/without GSPE (100 μg/ml) in the presence/absence of PbAc (100 μM)...

Luteolin (Lut) belongs to the flavonoid family with various beneficial bioactivities. Here, we investigated whether Lut attenuate mercuric chloride (HgCl2)-induced renal injury in rat. We found that oral gavage administration of Lut (80mg/kg) alleviated anemia and renal histology upon HgCl2 treatment (80mg/L). Lut also significantly reduced HgCl2-induced oxidative stress and inflammatory, presenting as the reduced malondialdehyde (MDA) formation, increased glutathione (GSH) level, and inhibited activation of nuclear factor kappa B (NF-κB)...

The carcinogenic potential of roxadustat (FG-4592), a novel orally active, heterocyclic small molecule inhibitor of hypoxia-inducible factor prolyl hydroxylase (HIF-PH) enzymes in clinical development for treatment of anemia, was evaluated in CD-1 mice and Sprague Dawley rats. Inhibition of HIF-PH by roxadustat leads to a rapid increase in cytoplasmic HIF-α concentrations, followed by translocation of HIF-α to the nucleus and upregulation of HIF-responsive genes, including erythropoietin. Roxadustat was dosed by oral gavage 3 times weekly (TIW) for up to 104 weeks in mice at 0, 15, 30, and 60 mg/kg and in rats at 0, 2...

Chronic kidney disease (CKD) is accompanied by a variety of complications, typically renal anemia and kidney fibrosis. Accordingly, it is desirable to develop the novel therapeutics that can treat these CKD conditions. Since nitric oxide (NO) has multiple functions including hypoxia inducible factor (HIF) stabilizing, anti-inflammatory, anti-oxidative and anti-apoptoic activities, the use of NO for the CKD therapy has attracted considerable interest. Here, we evaluate the therapeutic impacts of S-nitrosated human serum albumin (SNO-HSA), a long-lasting NO donor, on two animal models of CKD...

Plasma levels of FGF23 are increased in patients with chronic kidney disease. Beside its role in phosphate homeostasis, iron deficiency and anemia are associated with increased FGF23 plasma levels. Recently, FGF23 plasma levels were shown to be increased in mice after treatment with hypoxia inducible factor-proline hydroxylase (HIF-PH) inhibitors which are strong inducers of erythropoietin and erythropoiesis and are known to modulate iron uptake and availability. Therefore we investigated a potential context between expression of FGF23 and stimulation of erythropoiesis using a HIF-PH inhibitor and erythropoietin in rats...

The prevalence of diabetes mellitus is steadily growing throughout the world. Traditional medicine has an excellent potential in the treatment of diabetes mellitus. The present study was undertaken to evaluate the potential antidiabetic effect of peppermint essential oil (PEO) on streptozotocin (STZ) and nicotinamide induced diabetic rats. Diabetes was induced in rats fasting overnight by the intraperitoneal administration of nicotinamide followed by a single dose of STZ. After 72h, two groups of diabetic rats were treated with different doses of PEO (40 and 80mg/kg BW) respectively and one group was treated with the standard hypoglycemic agent glibenclamide...

Erythropoietin (EPO) is the main hormone driving mammalian erythropoiesis, with activity mediated via the surface receptor, EPO-R, on erythroid progenitor cells. Recombinant human EPO is currently used clinically for the treatment of anemia in patients with end-stage renal disease, and in certain cancer patients suffering from anemia induced either by the tumor itself or by chemotherapy. EPO-R expression is also detected in non-erythroid cells, including macrophages present in the peritoneum, spleen, and bone marrow (BM)...

Iron deficiency anemia is a frequent complication in clinical conditions such as chronic kidney disease, chronic heart failure, inflammatory bowel disease, cancer, and excessive blood loss. Given the ability of iron to catalyze redox reactions, iron therapy can be associated with oxidative stress. The lung is uniquely susceptible to oxidative stress, and little is known about the effects of intravenous iron treatment in this organ. This study characterized changes in markers of oxidative/nitrosative stress and inflammation in the lung of non-iron deficient, non-anemic rats treated with five weekly doses (40 mg iron per kg body weight) of low molecular weight iron dextran (LMWID), iron sucrose (IS), ferric carboxymaltose (FCM), ferumoxytol (FMX), iron isomaltoside 1000 (IIM), or saline (control)...

Amphotericin B (AmB) is widely applied in treatment of systemic fungal infections. However, the emergence of severe adverse effects, such as nephrotoxicity, hepatotoxicity and hemolytic anemia, can limit its clinical use. Poly(lactide-co-glycolide) (PLGA) or poly(lactide-co-glycolide)-poly(ethylene glycol) (PLGA-PEG) blend nanoparticles containing AmB were developed with the aim to decrease AmB toxicity and propose the oral route for AmB delivery. Nanoparticles were characterized by particle size, polydispersity index, Fourier transform infrared spectroscopy, differential scanning calorimetry and X-ray diffraction analyses...

BACKGROUND: The cardiorenal syndrome (CRS) is a major health problem in our aging population. The term was introduced to cover disorders of the kidneys and heart, whereby dysfunction of one organ may induce dysfunction of the other. As the natural history of the CRS is mostly slow, hence difficult to explore in clinical trials, adequate animal models combining cardiovascular and renal disease are required. Therefore, we developed and characterized a usable model for CRS type 4, i.e. chronic kidney disease (CKD) causing cardiac dysfunction...

Neuronal apoptotic cell death plays an important role in many neurological disorders, including Alzheimer's disease, Parkinson's disease, and ischemic stroke. Spatholobi Caulis (SC) has been widely used in traditional herbal medicine for the treatment of cancer, inflammation, viral infection, and anemia. However, the protective effects of SC extract (SCE) against apoptotic cell death in the brain have not been reported. We investigated the protective effects of SCE against neuronal injury etoposide-induced neurotoxicity and in rats subjected to focal transient ischemic stroke middle cerebral artery occlusion (MCAO) for 45 min, followed by 7 days of reperfusion...
