MicroRNA-130b inhibits cerebral ischemia/reperfusion induced cell apoptosis via regulation of IRF1

OBJECTIVE: Cerebral ischemia/reperfusion (CIR) frequently causes serious disabilities and correlates with certain neurological processes. Some studies have shown that microRNAs (miRNAs) exert a neuroprotective effect by modulating the inflammatory process in CIR. However, the biofunction and the mechanism of miR-130b in CIR need to be fully elucidated. MATERIALS AND METHODS: An oxygen-glucose deprivation/reperfusion (OGD/R) model was constructed using SH-SYSY cell line to analyze the function of miR-130b in CIR. Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was used to examine the expression levels of miR-130b and IRF1. Western blot was performed to detect the protein levels of IRF1, Bax, and Bcl-2. Cell viability was determined using MTT (3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assays. Dual-Luciferase reporter assay was conducted to confirm the target gene of miR-130b. RESULTS: In this study, we found that miR-130b level was prominently decreased after treatment with OGD/R. Through gain and loss assays, we concluded that miR-130b restoration promoted cell proliferation and inhibited cell apoptosis in OGD/R-treated cells. Moreover, we also identified IRF1 as an important target of miR-130b. Additionally, IRF1 knockdown remarkably abrogated the protection mediated by miR-130b against the injuries in OGD/R-treated cells. CONCLUSIONS: Taken together, our results suggested that miR-130b facilitated cell viability and suppressed cell apoptosis of CIR via negatively regulating of IRF1.

Copper(ii) complexes with NNO ligands: synthesis, crystal structures, DNA cleavage, and anticancer activities

Three novel copper(ii) complexes, Cu(L1)(2) (1), Cu(L2)(2)2DMF (2), and Cu(L3)(2)2DMF (3), were synthesized using three aroylhydrazone ligands, (E)-2-hydroxy-N ‘-(1-(pyrazin-2-yl)ethylidene)benzohydrazide (HL1), (E)-3-hydroxy-N ‘-(1-(pyrazin-2-yl)ethylidene)benzohydrazide (HL2) and (E)-4-hydroxy-N ‘-(1-(pyrazin-2-yl)ethylidene)benzohydrazide (HL3). The complexes were characterized by elemental analysis, infrared (IR), and Ultraviolet-visible light (UV-vis) spectroscopy. The X-ray crystal structures of the complexes all possess a distorted octahedral coordination geometry. Both an absorption spectral titration and a competitive binding assay (ethidium bromide, 4 ‘,6-diamidino-2-phenylindole (DAPI), and methyl green) revealed that complexes 2 and 3 bind readily to calf thymus DNA (ctDNA) through intercalative and minor groove binding modes. Complexes 2 and 3 also exhibited oxidative cleavage of supercoiled plasmid DNA (pUC19) in the presence of ascorbic acid as an activator. Cytotoxicity studies showed that complexes 2 and 3 possessed high cytotoxicities toward the HeLa human cervical cancer cell line, but weak toxicities toward the L929 normal mouse fibroblast cell line. We therefore have reason to believe that complexes 2 and 3 both show potential as promising anticancer candidate drugs.

Circ_0010729 regulates hypoxia-induced cardiomyocyte injuries by activating TRAF5 via sponging miR-27a-3p

Ischemic cardiomyopathy is a severe cardiovascular disease with high mortality. Circular RNAs (circRNAs) are widely regulated in diverse human diseases, including Ischemic cardiomyopathy. This study aimed to investigate a novel functional mechanism of circRNA circ_0010729 in hypoxia-induced cardiomyocyte injuries. Human cardiomyocytes (AC16) were exposed to hypoxia to mimic ischemic cardiomyopathy in vitro. Cell viability, apoptosis/necrosis and glycolysis progress, were determined using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay, flow cytometry assay and glycolysis stress test, respectively. Cell apoptosis was also assessed by the activity of cleaved caspase-3/7. The levels of glycolysis-related proteins and tumor necrosis factor receptor-associated factor 5 (TRAF5) were examined by western blot. The expression of circ_0010729 and miR-27a-3p was measured by real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR). The prediction about the targeted relationship was verified by dual-luciferase reporter assay, RNA immunoprecipitation (RIP) assay and RNA pull-down assay. As a result, hypoxia treatment inhibited cell viability, induced cell apoptosis and blocked glycolysis, however, these injuries were alleviated by circ_0010729 knockdown. MiR-27a-3p was targeted by circ_0010729, and miR-27a-3p inhibition reversed the role of circ_0010729 knockdown, leading to the deterioration of cell injuries. Further, TRAF5 was a target of miR-27a-3p, and circ_0010729 upregulated the expression of TRAF5 by sponging miR-27a-3p. MiR-27a-3p restoration enhanced cell viability, depleted cell apoptosis and promoted glycolysis of hypoxia-induced AC16 cells, while these effects were abolished by TRAF5 overexpression. In conclusion, circ_0010729 knockdown alleviated hypoxia-induced AC16 cell injuries by mediating the miR-27a-3p/TRAF5 axis.

Baicalin Inhibits Biofilm Formation and the Quorum-Sensing System by Regulating the MsrA Drug Efflux Pump in Staphylococcus saprophyticus

Staphylococcus saprophyticus (S. saprophyticus) is one of the main pathogens that cause serious infection due to its acquisition of antibiotic resistance. The efflux pump decreases antibiotic abundance, and biofilm compromises the penetration of antibiotics. It has been reported that baicalin is a potential agent to inhibit efflux pumps, biofilm formation, and quorum-sensing systems. The purpose of this study was to investigate whether baicalin can inhibit S. saprophyticus biofilm formation and the quorum-sensing system by inhibiting the MsrA efflux pump. First, the mechanism of baicalin inhibiting efflux was investigated by the ethidium bromide (EtBr) efflux assay, measurement of ATP content, and pyruvate kinase (PK) activities. These results revealed that baicalin significantly reduced the efflux of EtBr, the ATP content, and the activity of PK. Moreover, its role in biofilm formation and the agr system was studied by crystal violet staining, confocal laser scanning microscopy, scanning electron microscopy, and real-time polymerase chain reaction. These results showed that baicalin decreased biofilm formation, inhibited bacterial aggregation, and downregulated mRNA transcription levels of the quorum-sensing system regulators agrA, agrC, RNAIII, and sarA. Correlation analysis indicated that there was a strong positive correlation between the efflux pump and biofilm formation and the agr system. We demonstrate for the first time that baicalin inhibits biofilm formation and the agr quorum-sensing system by inhibiting the efflux pump in S. saprophyticus. Therefore, baicalin is a potential therapeutic agent for S. saprophyticus biofilm-associated infections.

Nickel-Coordinated Carbon Nitride as a Metallaphotoredox Platform for the Cross-Coupling of Aryl Halides with Alcohols

Light-driven dual catalysis that combines photosensitizers and transition-metal complexes has become a powerful approach for diverse cross-coupling reactions. Heterogeneous photocatalysts recently have gained growing attention to build such catalytic system for controllable reaction kinetics and enhanced activity. Incorporating a metal catalyst into the framework of the photocatalyst could endow unique metallaphotoredox platforms. Herein, we assemble carbon nitride and nickel (C3N4-Ni) via direct coordination of Ni2+ to C3N4 nitrogen, for visible-light-driven carbon-oxygen cross-coupling. By operating with an imidazole auxiliary ligand, C3N4-Ni efficiently catalyzed etherification of a variety of aryl bromides with alcohols or hydroxylation with water, exhibiting turnover numbers of >500. Ni maintained as isolated single site without aggregation after photoreaction and the recovered catalyst demonstrate sustained activity without additional Ni loading. Our work signifies the potential of uniting dual catalysis in well-designed sensitizer-metal architecture for complex organic transformations.

Evaluation of the Antiviral Potential of Halogenated Dihydrorugosaflavonoids and Molecular Modeling with nsP3 Protein of Chikungunya Virus (CHIKV)

Antiviral therapy is crucial for the circumvention of viral epidemics. The unavailability of a specific antiviral drug against the chikungunya virus (CHIKV) disease has created an alarming situation to identify or develop potent chemical molecules for remedial management of CHIKV. In the present investigation, in silico studies of dihydrorugosaflavonoid derivatives (5a-f) with non-structural protein-3 (nsP3) were carried out. nsP3 replication protein has recently been considered as a possible antiviral target in which crucial inhibitors fit into the adenosine-binding pocket of the macrodomain. The 4′-halogenated dihydrorugosaflavonoids displayed intrinsic binding with the nsp3 macrodomain (PDB ID: 3GPO) of CHIKV. Compounds 5c and 5d showed docking scores of -7.54 and -6.86 kcal mol(-1), respectively. Various in vitro assays were performed to confirm their (5a-f) antiviral potential against CHIKV. The non-cytotoxic dose was determined by 3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and was found to be <100 mu M. The compounds 5c and 5d showed their inhibitory potential for CHIKV, which was determined through cytopathic effect assay and plaque reduction assay, which show inhibition up to 95 and 92% for 70 mu M concentration of the compounds, respectively. The quantitative real-time polymerase chain reaction assay result confirmed the ability of 5c and 5d to reduce the viral RNA level at 70 mu M concentration of compounds to nearly 95 and 93% concentration, respectively, in cells with CHIKV infection. Further, the CHIKV-inhibitory capacity of these compounds was corroborated by execution of immunofluorescence assay. The executed work will be meaningful for the future research of studied dihydrorugosaflavonoids against prime antiviral entrants, leading to remedial management to preclude CHIKV infection.

Quadruple hydrogen bonded hyperbranched supramolecular polymers with aggregation-induced emission for artificial light-harvesting

In the present work, a tetraphenylethylene (TPE) derivative with four ureidopyrimidinones (TPE-tetraUPy) was synthesized through a two-step reaction, which could make up supramolecular hyperbranched polymers in CHCl3 through quadruple hydrogen bonding interactions with aggregation-induced emission (ME). The supramolecular hyperbranched polymers were characterized by Fourier transformed infrared (FT-IR), viscosity measurement, H-1 NMR spectra, and steady-state spectra. The as-prepared supramolecular hyperbranched polymers can further self-assemble to form nanoparticles in CHCl3/hexane mixture (1:99, v/v) or form nanoparticles in uniform shape and size using the miniemulsion method with cetyltrimethyl ammonium bromide (CTAB) as a surfactant. From the supramolecular nanoparticles prepared in the miniemulsion method, we construct a light-harvesting system to study the excitation energy transfer properties by using the electrostatic assembly of negatively charged sulforhodamine 101 (SR101) on the nanoparticles, which exhibited a high energy transfer efficiency (37.2%) and antenna effect (30.7).

Studies on the self-aggregation, interfacial and thermodynamic properties of a surface active imidazolium-based ionic liquid in aqueous solution: Effects of salt and temperature

The influence of four sodium salts (NaCl, NaBr, Na2SO4, and Na3PO4) on the self-aggregation, interfacial, and thermodynamic properties of a surface active ionic liquid (1-hexadecyl-3-methylimidazolium chloride, C(16)MImCl) has been explored in aqueous solutions by conductometry, tensiometry, spectrofluorimetry, isothermal titration calorimetry and dynamic light scattering (DLS). Analyses of the critical micellar concentration (cmc) values indicate that the anions of the added salts promote the self-aggregation of C(16)MImCl in the order: Cl- < Br- < PO43-< SO42-. Dehydration of imidazolium head groups, in general, governs the process of micellization of aqueous C(16)MImCl in presence of the investigated salts within the investigated temperature range (298.15-318.15 K), while the melting of iceberg takes the leading role below 303.15 K for the C(16)MImCl-Na3PO4 system. The results indicate that addition of salt leads to a greater spontaneity of micellization, and that exothermicity prevails in these systems. Differential effect of the salts on the interfacial properties of C(16)MeImCl has been interpreted on the basis of the coupled influence of the electrostatic charge neutralization of surfactants at the interface, and the van der Wa-als repulsion of surfactant tails and electrostatic repulsion of surfactant head groups. C(16)MeImCl has been predicted to form spherical micelles in presence of varying amounts of NaCl, Na2SO4 and Na3PO4, while there occurs probably a transition in the micellar geometry from spherical to non-spherical shape when added NaBr concentration exceeds 0.01 mol.kg(-1). Fluorescence studies demonstrate that a combined quenching mechanism is operative for the quenching of pyrene fluorescence in the investigated C(16)MImCl-salt systems. Micellar aggregation numbers obtained from Steady State Fluorescence Quenching method have always been found be somewhat smaller than those estimated from Time Resolved Fluorescence Quenching method. The order of instability of the C(16)MImCl-micelles ascertained from Zeta potential measurements conform to what has been inferred from the cmc values. The hydrodynamic diameters of C(16)MImCl-micelles, obtained from DLS studies, have been found to increase with increasing salinity of the solutions. (C) 2020 Published by Elsevier B.V.
