hsa_circ_0092306 Targeting miR-197-3p Promotes Gastric Cancer Development by Regulating PRKCB in MKN-45 Cells

Gastric cancer (GC) is one of the most common cancers worldwide and is thus a global cancer burden. Here, we focused on a novel circular RNA hsa_circ_0092306 and explored the potential molecular mechanism to provide a new target for and novel insights into GC treatment. The GEO microarray was mined and analyzed with R software. Sanger sequencing and RNase R assay were applied to verify the identification of hsa_circ_0092306. Quantitative real-time PCR and western blot were performed to measure the mRNA and protein levels. Pull-down and luciferase reporter assays were conducted to confirm the target relationships. Annexin V-PI apoptosisflowcytometry, 3-(4,5Dimethylthiazol- yl)-2,5Dimethylthiazol-2-yl)-2,5diphenyltetrazolium bromide (MTT), wound healing, and Transwell assays were applied to detect cell apoptosis, viability, migration, and invasion in MKN-45 cells, respectively. A xenograft in vivo experiment was conducted to confirm the cell experiment results. hsa_circ_0092306 was upregulated in GC tissues and GC cells, and promoted GC development in MKN-45 cells. hsa_circ_0092306 inhibited tumor suppressor miR-197-3p expression but promoted tumor promotor protein kinase C beta (PRKCB) expression in MKN-45 cells. hsa_circ_0092306 and PRKCB had a common target (miR-197-3p) and were negatively related to miR-197-3p expression. hsa_circ_0092306 promoted the development of GC by regulating the pathway of miR-197-3p/PRKCB in MKN-45 cells.

Immunomodulatory effects of flavonoids: An experimental study on natural-killer-cell-mediated cytotoxicity against lung cancer and cytotoxic granule secretion profile

Background: A new approach involving immune-cell-mediated cancer therapy has been adopted extensively for the sake of lung cancer treatments by utilizing natural killer (NK) cells. NK cell activity can be enhanced with certain agents, and among them are flavonoids. Thus, this study was conducted to investigate the immunomodulatory roles of apigenin, luteolin and quercetin on NK cell activity against lung cancer cells and on the secretions of perforin and granulysin profile. Methods: The NK-92 cells were grown in complete alpha-Minimum Essential Medium (MEM). NCI-H460 lung cancer cells were cultured in Roswell Park Memorial Institute 1640 media. NK cell activity against lung cancer cells were done using MTT(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. The secretions of perforin and granulysin profiles were then analysed using enzyme-linked immunosorbent assay. Results: Apigenin, luteolin and quercetin significantly increased the NK-cell-mediated cytotoxic activity against lung cancer cells at concentrations 12.5 mu g/ml and 25 mu g/ml (P < 0.001). The secretion levels of perforin and granulysin from NK cells were also significantly enhanced with apigenin and luteolin treatment but not with quercetin. Conclusions: All three flavonoid compounds possessed some significant immunomodulatory actions on NK cell cytotoxic activity and granule secretion profiles towards lung cancer therapy.

Evaluation of Anticancer Activity and Apoptosis inducing ability of Suaeda monoica on Breast Cancer Cell Line

Breast cancer is the most frequently diagnosed cancer in women but rarely found in men. It is an invasive tumor majorly formed in lobules or ducts of the breast. The present study investigates the anticancer activity of Suaeda monoica with different solvent extracts against estrogen receptor-positive MCF-7 using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (M) assay. The different solvents used for this study were ethanol, methanol, acetone and diethyl ether. The diethyl ether extract of the plant showed the highest anticancer activity with an IC50 value of 186.78 mu g/ml in comparison with other solvent extracts. The morphological changes were then observed under an inverted phase-contrast microscope. Fluorescence imaging using propidium iodide stain was done to confirm the changes associated with apoptosis. The study shows that the plant has appreciable anticancer activity against the MCF-7 cell line and further the bioactive compound responsible for the anticancer activity should be isolated and purified.

Design and Fabrication of Anionic/Cationic Surfactant Foams Stabilized by Lignin-Cellulose Nanofibrils for Enhanced Oil Recovery

It has been decades since foams were adapted in further developing water-flooded oilfields. Foam stability is regarded as the governing factor that directly determines the enhanced oil recovery (EOR) efficiency of a foam injection. In this paper, we focus on a series of anionic surfactant-based foaming agent [sodium dodecyl sulfate (SDS)] and non-ionic surfactant-based foaming agent [alkyl polyglycoside (APG)] stabilized by lignin-cellulose nanofibrils (LCNFs), in the absence or presence of a cationic surfactant [hexadecyltrimethylammonium bromide (CTAB)]. Particular attention was placed on the proportion of LCNFs/SDS/CTAB and LCNFs/APG/CTAB as well as their synergism assessment, including foamability, drainage half-time, foam decay, surface tension, and micromorphology. Our results demonstrate that the synergism between cationic/anionic surfactants and LCNFs retarded film drainage and, thus, produced robust foams. The synergism mechanism, contributed to the electrostatic reaction and hydrogen bond between LCNFs and the surfactants, has been discussed and proposed.

Metallaphotoredox aryl and alkyl radiomethylation for PET ligand discovery

Positron emission tomography (PET) radioligands (radioactively labelled tracer compounds) are extremely useful for in vivo characterization of central nervous system drug candidates, neurodegenerative diseases and numerous oncology targets(1). Both tritium and carbon-11 radioisotopologues are generally necessary for in vitro and in vivo characterization of radioligands(2), yet there exist few radiolabelling protocols for the synthesis of either, inhibiting the development of PET radioligands. The synthesis of such radioligands also needs to be very rapid owing to the short half-life of carbon-11. Here we report a versatile and rapid metallaphotoredox-catalysed method for late-stage installation of both tritium and carbon-11 into the desired compounds via methylation of pharmaceutical precursors bearing aryl and alkyl bromides. Methyl groups are among the most prevalent structural elements found in bioactive molecules, and so this synthetic approach simplifies the discovery of radioligands. To demonstrate the breadth of applicability of this technique, we perform rapid synthesis of 20 tritiated and 10 carbon-11-labelled complex pharmaceuticals and PET radioligands, including a one-step radiosynthesis of the clinically used compounds [C-11]UCB-J and [C-11]PHNO. We further outline the direct utility of this protocol for preclinical PET imaging and its translation to automated radiosynthesis for routine radiotracer production in human clinical imaging. We also demonstrate this protocol for the installation of other diverse and pharmaceutically useful isotopes, including carbon-14, carbon-13 and deuterium.

Cytotoxic effect of graphene oxide-functionalized gold nanoparticles in human breast cancer cell lines

As the global burden of cancer is on the rise it is essential to develop alternate therapeutics that confer zero or minimum side effects. In this experiment, we evaluated the anticancer efficacy of graphene oxide-functionalized gold nanoparticles (GO-AuNPs) in human breast cancer cell lines MCF7 and MDA-MB-231. MTT assay revealed a dose-dependent decline in cancer cell survival. Significant alterations were detected in normal cellular morphology after treatment. Two different cell staining methods viz. acridine orange-ethidium bromide staining and annexin-cy3.18/6-carboxyfluorescein diacetate staining confirmed that the GO-AuNPs rendered their detrimental effect in cancer cells through apoptosis. To decipher the mode of apoptosis Western blotting was performed in which expression pattern of several proteins (PARP1, P53, P21, Bcl2, Bax, Caspase 9 and Caspase 3) established the intrinsic apoptosis pathway in these cell lines after GO-AuNP exposure. Intracellular calcium level, as measured by energy dispersive X-ray fluorescence analysis, was present at non-detectable level following treatment that can be linked to the cell cycle arrest and apoptotic cell death in them. Thus, GO-AuNPs were found effective in both types of human breast cancer cells viz. hormone-responsive MCF7 and chemoresistant MDA-MB-231 and can be considered as a highly potential anticancer agent in breast cancer therapy.

Combination of Imidazolium Bromine and Tetrabutylammonium Bromide for CH4 Purification from Simulated Biogas by Hydrate-Based Gas Separation

Biogas is one of the green energy resources. To enhance usage of biogas (64.0 mol % CH4/CO2) and reduce the greenhouse effect, CH4 purification by the hydrate-based gas separation (HBGS) technology was studied in this work. Green solvent ionic liquid [BMIm] Br and thermodynamic promoter tetrabutylammonium bromide (TBAB) were added as hydrate additives to investigate their influence on hydrate formation. [BMIm] Br has an inhibition effect on CH4 and CH4/CO2 hydrate phase equilibrium. The combination of [BMIm] Br and TBAB decreased CH4/CO2 hydrate phase equilibrium pressure under identical temperature. Kinetics of CH4 and CO2 hydrate formation in [BMIm] Br solution were investigated. Gas uptake in the hydrate phase increased when [BMIm] Br concentrations changed from 1000 to 2000 and 3000 ppm. The influence factors of gas liquid ratio, temperature, pressure, and concentration on biogas hydrate separation were studied. Separation results were analyzed based on CH4 mole fraction in the residual gas, CH4 recovery, separation factor, phase equilibrium constant, and hydrate ratio of CH4 and CO2. CH4 in residual-phase gas can be enriched from initial 64.00 to 79.13 mol %, and the maximum CH4 recovery was 85.19%. For the combination of TBAB and [BMIm] Br on simulated biogas hydrate separation study, the CH4 value in residual gas was enhanced to 76.96 mol % and CH4 recovery was above 90%. The synergistic effect of TBAB + [BMIm] Br was not obvious compared to the result in pure [BMIm] Br solution, and gas storage in the hydrate phase decreased on the whole.

Understanding the mass-transfer of Br species in an aqueous and quaternary ammonium polybromide biphasic system via particle-impact electrochemical analysis

In this article, we present our studies on the mass-transfer of Br species existing in an acidic aqueous solution containing quaternary ammonium bromide (QBr) during electro-oxidation of Br-. We found that the mass-transfer of quaternary ammonium polybromide (QBr(2n)(+1)) droplets toward a Pt ultra-microelectrode (UME) are mainly governed by diffusion, although their migration is not negligible. We further revealed that the migration of Br- in a QBr(2n)(+1) droplet significantly affects the current associated with the electro-oxidation of Br- during the collision of the droplet on a Pt UME. Finally, we observed current spikes in which the current decayed and reached a certain steady state with a non-zero value. These were interpreted based on Br–transfer at the interface between water and a QBr(2n)(+1) droplet (water vertical bar QBr(2n+1)) using finite element analysis. The presented electrochemical analyses would be potentially important to understand the operating mechanism of redox flow batteries (RFBs) using Br-/Br-2 as a half redox reaction to inhibit the self-discharge that occurs during the charging process.

Quantitative Structure-Cytotoxicity Relationship of 2-Arylazolylchromones and 2-Triazolylchromones

Background/Aim: 4H-1-Benzopyran-4-one (chromone), present in various flavonoids as a backbone structure, has been used for the synthesis of anticancer drugs. The study aimed at investigating the cytotoxicity of eight 2-arylazolylchromones and twelve 2-triazolylchromones against four human oral squamous cell carcinoma (OSCC) cell lines and three human normal mesenchymal oral cells, and then performed a quantitative structure-activity relationship (QSAR) analysis. Materials and Methods: Cell viability was determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide method. The distribution of cells to various phases of cell cycle was determined by cell cycle analysis. A total of 3,218 physicochemical, structural and quantum chemical features were calculated for QSAR analysis from the most stabilized structure optimized using CORINA. Results: 2-[4-(4-fluorophenyl)-1H-imidazol-1-yl]-4H-1-benzopyran-4-one [6] had the highest tumor-specificity (TS), comparable with that of 5-flurouracil (5-FU) and doxorubicin, inducing cytostatic growth inhibition, accumulation of G(2)+M phase cells with no cells in the G(1) phase. All eight 2-triazolylchromones showed much lower tumor-specificity, confirming our previous finding. Tumor-specificity was also correlated with 3D shape, topological shape, size, ionization potential, and the presence of more than two aromatic rings in the molecule and imidazole ring in the nitrogen-containing heterocyclic ring. Conclusion: [6] can be a lead compound for designing anticancer drugs.
