Naringenin-loaded nanoparticles modulate HIF-driven oxygen-sensing pathways in lung adenocarcinoma cells

BMC Research Notes, Год журнала: 2025, Номер 18(1)

Опубликована: Фев. 12, 2025

Abstract Background Hypoxia is a common symptom of lung cancer. Proliferation and neovascularization mediated by hypoxia-inducible factors (HIF) influence several adaptations. It has recently been established that naringenin (NAR) its nanoparticles are chemo-preventive flavonoids in Aim Adjust HIF activity reviving oxygen-sensing enzyme while considering possible therapeutic targets. Method The bindings NAR to target proteins were examined using computational modeling techniques. Additionally, (NARNPs) synthesized characterized. Normal fibroblast cells A549 used determine cytotoxicity. Colorimetric analysis α-ketoglutarate detection for hydroxylases. Results According molecular modeling, have high affinity. PHD FIH activities significantly stimulated. Conclusion NARNPs diminish hypoxia cancer stimulating

New Insights Into the Effects of Electrode Polarization of Chitosan on Graphene Nanomaterials

Advanced Materials Interfaces, Год журнала: 2025, Номер unknown

Abstract The efficient transfer of electrons between the electrode and analyte, influenced by polarization (EP), is a crucial yet often overlooked factor in assessing performance electrochemical systems. This study explores use chitosan as an EP suppressor for graphene oxide (GO) reduced (RGO) ferri/ferro cyanide redox probe, using cyclic voltammetry (CV) impedance spectroscopy (EIS) techniques. CV results indicate that GO has greater pseudocapacitance than RGO does, indicating abundance oxygen‐containing functional groups facilitate stronger interfacial interactions with chitosan. By reducing capacitive current, shown through EIS, sensitivity toward Fe 2+/3+ couple at double layer enhanced. These findings align density theory (DFT) calculations, which charge distortion favoring chitosan, thereby allowing more intrinsic electron within aromatic rings GO/RGO nanomaterials. research holds significant potential advancing development sensors energy storage devices.

Lead contamination in water poses significant health risks, making its removal imperative. In this study, magnetic strontium ferrite (SrFe12O19) nanoparticles were facilely synthesized by the Pechini sol–gel method and subsequently functionalized with a novel chitosan–Schiff base ligand to obtain inorganic/organic nanocomposite for removing Pb(II) ions from aqueous solutions. The was through reaction of chitosan 2,4,5-trihydroxybenzaldehyde. presence two X-ray diffraction (XRD) peaks at 2Ɵ = 10.5° 20.5°, alongside characteristic SrFe12O19 peaks, confirmed functionalization ligand. Additionally, decrease saturation magnetization value 40.29 emu/g pure 17.32 further verified functionalization. carbon (C) nitrogen (N) atoms energy-dispersive (EDX) pattern nanocomposite, addition iron (Fe), (Sr), oxygen (O), also nanocomposite’s maximum adsorption capacity 390.63 mg/g. Moreover, process is endothermic, spontaneous, chemical, occurring via complexation -C=N -OH groups, it fits well Langmuir equilibrium isotherm pseudo-second-order kinetic equation.
