“…7,8 More importantly, no sign of toxicity was observed in animals or humans treated with CUR, indicating its in vivo safety. 9 However, its clinical application is still restricted by poor solubility in aqueous solution, poor oral bioavailability and extensive first-pass metabolism. 10 Nanotechnology has been widely used in the field of drug delivery and cancer therapy due to its advantages in developing aqueous-based formulations for hydrophobic drugs.…”

Background It has been widely reported that curcumin (CUR) exhibits anticancer activity and triggers the apoptosis of human A549 non-small-cell lung cancer (NSCLC) cells. However, its application is limited owing to its poor solubility and bioavailability. Therefore, there is an urgent need to develop a new CUR formulation with higher water solubility and better biocompatibility for clinical application in the future. Materials and methods In this study, CUR-loaded methoxy polyethylene glycol–polylactide (CUR/mPEG–PLA) polymeric micelles were prepared by a thin-film hydration method. Their characteristics and antitumor effects were evaluated subsequently. Results The average size of CUR/mPEG–PLA micelles was 34.9±2.1 nm with its polydispersity index (PDI) in the range of 0.067–0.168. The encapsulation efficiency and drug loading were 90.2%±0.78% and 9.1%±0.07%, respectively. CUR was constantly released from the CUR/mPEG–PLA micelles, and its cellular uptake in A549 cells was significantly increased. It was also found that CUR/mPEG–PLA micelles inhibited A549 cell proliferation, increased the cell cytotoxicity, induced G2/M stage arrest and promoted cell apoptosis. Moreover, the CUR/mPEG–PLA micelles suppressed the migration and invasion of A549 cells more obviously than free CUR. Additionally, CUR/mPEG–PLA micelles inhibited human umbilical vein endothelial cells migration, invasion and corresponding tube formation, implying the antiangiogenesis ability. Its enhanced antitumor mechanism may be related to the reduced expression of vascular endothelial growth factor, matrix metalloproteinase (MMP)-2, MMP-9 and Bcl-2 as well as the increased expression of Bax. Conclusion The mPEG–PLA copolymer micelles can serve as an efficient carrier for CUR. The CUR/mPEG–PLA micelles have promising clinical potential in treating NSCLC.

“…Research for more than two decades has revealed the pleiotropic nature of the biological effects of this molecule. More than 7000 published articles have shed light on the various aspects of curcumin, including its antioxidant, hypoglycemic, anti-inflammatory and anti-cancer activities (Ghosh et al, 2015). Apart from these wellknown actions, this natural compound also exerts its beneficial effects by modulating different signalling molecules including transcription factors, tumour suppressor genes, chemokines, cytokines, etc.…”

“…To this end, in the present study, we assessed 12 pure natural compounds with the potential to modulate iron metabolism. All these compounds are extracts from traditional Chinese herbal medicinal plants, and many of them have been reported to be effective therapeutically for multiple disorders, including inflammation, oxidative injuries and cardiovascular diseases (12)(13)(14)(15)(16)(17)(18)(19)(20). According to the Chinese Pharmacopoeia (21), all of these compounds are capable of improving microcirculation and have the potential to modulate blood cell formation.…”

Abstract. Systemic iron homeostasis is strictly controlled under normal conditions to ensure a balance between the absorption, utilization, storage and recycling of iron. The hepcidin-ferroportin (FPN) axis is of critical importance in the maintenance of iron homeostasis. Hepcidin deficiency gives rise to enhanced dietary iron absorption, as well as to increased iron release from macrophages, and this in turn results in iron accumulation in the plasma and organs, and is associated with a range of tissue pathologies. Low hepcidin levels have been demonstrated in most forms of hereditary hemochromatosis (HH), as well as in β-thalassemia. Therapies that increase hepcidin concentrations may potentially play a role in the treatment of these iron overload-related diseases. To date, natural compounds have not been extensively investigated for this purpose, to the best of our knowledge. Thus, in the present study, we screened natural compounds that have the potential to regulate hepcidin expression. By performing hepcidin promoter-luciferase assay, RT-qPCR and animal experiments, we demonstrated that icariin and berberine were potent stimulators of hepcidin transcription.Mechanistic experiments indicated that icariin and berberine increased hepcidin expression by activating the signal transducer and activator of transcription 3 (Stat3) and Smad1/5/8 signaling pathways. The induction of hepcidin was confirmed in mice following icariin administration, coupled with associated changes in serum and tissue iron concentrations. In support of these findings, the icariin analogues, epimedin A, B and C, also increased hepatic hepcidin expression. However, these changes were not observed in hepcidin-deficient [Hamp1 -/-or Hamp1-knockout (KO)] mice following icariin administration, thereby verifying hepatic hepcidin as the target of icariin. Although berberine exhibited a robust capacity to promote hepcidin expression in vitro, it failed to alter hepcidin expression in mice. Taken together, the findings of the present study suggest that icariin exhibits a robust capacity to increase hepatic hepcidin expression and to modulate systemic iron homeostasis. The present study therefore highlights the significance of using natural compounds to ameliorate iron disorders through the regulation of hepcidin expression. IntroductionIron is an essential metal involved in a large array of biological processes, such as energy metabolism, DNA replication and other important cellular functions (1-3). Systemic iron homeostasis is accurately and strictly governed to ensure a balance between iron absorption, utilization and storage in mammals (4). Hepcidin is the central hormone secreted by hepatocytes that plays a fundamental role in the regulation of iron flow through limiting dietary iron absorption from the duodenum and reducing iron egress from macrophages (5). Hepcidin achieves this effect by binding to its receptor, ferroportin (FPN; the only known iron exporter thus far), on the plasma membrane of target cells and inducing its internalization ...
