ALDH2 is an enzyme involved in redox homeostasis as well as the detoxification process in alc. metabolism Nearly 8% of the world′s population have an inactivating mutation in the ALDH2 gene. Herein, we report that ALDH2 is expressed in skeletal muscle and is localized to the mitochondrial fraction. Oxidative muscles had a higher amount of ALDH2 protein than glycolytic muscles. We next comprehensively investigated whether ALDH2 knockout in mice induces mitochondrial adaptations in gastrocnemius muscle (for example, content, enzymic activity, respiratory function, supercomplex formation, and functional networking). We found that ALDH2 deficiency resulted in partial mitochondrial dysfunction in gastrocnemius muscle because it increased mitochondrial reactive oxygen species (ROS) emission (2′,7′-dichlorofluorescein and MitoSOX oxidation rate during respiration) and the frequency of regional mitochondrial depolarization. Moreover, we determined whether ALDH2 deficiency and the related mitochondrial dysfunction trigger mitochondrial stress and quality control responses in gastrocnemius muscle (for example, mitophagy markers, dynamics, and the unfolded protein response). We found that ALDH2 deficiency upregulated the mitochondrial serine protease Omi/HtrA2 (a marker of the activation of a branch of the mitochondrial unfolded protein response). In summary, ALDH2 deficiency leads to greater mitochondrial ROS production, but homeostasis can be maintained via an appropriate stress response.

An Arabidopsis mutant over-expressing subtilase SBT4.13 uncovers the role of oxidative stress in the inhibition of growth by intracellular acidification was written by Bissoli, Gaetano;Munoz-Bertomeu, Jesus;Bueso, Eduardo;Sayas, Enric;Vilcara, Edgardo A.;Felipo, Amelia;Ninoles, Regina;Rubio, Lourdes;Fernandez, Jose A.;Serrano, Ramon. And the article was included in International Journal of Molecular Sciences in 2020.Reference of 76-54-0 This article mentions the following:

Intracellular acid stress inhibits plant growth by unknown mechanisms and it occurs in acidic soils and as consequence of other stresses. In order to identify mechanisms of acid toxicity, we screened activation-tagging lines of Arabidopsis thaliana for tolerance to intracellular acidification induced by organic acids. A ominant mutant, Sbt4.13-1D, was isolated twice and shown to over-express subtilase SBT4.13, a protease secreted into endoplasmic reticulum. Activity measurements and immuno-detection indicate that the mutant contains less plasma membrane H+-ATPase (PMA) than wild type, explaining the small size, elec. depolarization and decreased cytosolic pH of the mutant but not organic acid tolerance. Addition of acetic acid to wild-type plantlets induces production of ROS (Reactive Oxygen Species) measured by dichlorodihydrofluorescein diacetate. Acid-induced ROS production is greatly decreased in sbt4.13-1D and atrboh-D,F mutants. The latter is deficient in two major NADPH oxidases (NOXs) and is tolerant to organic acids. These results suggest that intracellular acidification activates NOXs and the resulting oxidative stress is important for inhibition of growth. The inhibition of acid-activated NOXs in the sbt4.13-1D mutant compensates inhibition of PMA to increase acid tolerance.

Peptide controlled assembly of palladium nanoparticles on high-aspect-ratio gold nanorods was written by Wagner, John Tyler;Long, Analeece K.;Sumner, Michael B.

The use of gold nanorods as a template for bimetallic applications, including plasmonics, imaging, and phototherapy, is widely studied due to the unique optical properties of the gold materials. Generally, gold nanorods prepared with a Ag-assisted method are used, with a typical aspect ratio (length vs. width) around 3, resulting in surface plasmons resonating within the UV-visible range. Due to these unique properties, gold nanorods are often combined with a catalytically active second metal to increase their range of applicability. The use of higher-aspect-ratio gold nanorods as a bimetallic template is an attractive alternative to the typical method as the longitudinal plasmon of these materials can be adjusted into the near-IR (NIR) range. This adjustment expands the applications of bimetallic Au nanorods in the second-NIR biol. window, which spans 1000-1700 nm. A materials-binding peptide, CPd4, is used to control the size and shape formation of palladium nanoparticles onto the surface of high-aspect-ratio gold nanorods. Through variation of the solvent used when attaching the peptide, the concentration of CPd4 retained on the nanorods can be manipulated. Higher concentrations of peptide, once palladium was added, were seen to result in smaller cubelike nanoparticles on the surface, whereas lower concentrations of peptide yielded larger spherical palladium nanoparticles. The ability to tune the size and shape of palladium nanorods on the gold nanorod surface allows for optimization of catalytic activity with applications in the NIR range.

Nanoparticles can potentially stimulate tumor microenvironments to elicit antitumor immunity. Herein, we demonstrate effective immunotherapy of colorectal cancer via systemic delivery of an immunostimulatory chemotherapeutic combination in nanoscale coordination polymer (NCP) core-shell particles. Oxaliplatin and dihydroartemesinin have contrasting physicochem. properties but strong synergy in reactive oxygen species (ROS) generation and anticancer activity. The combined ROS generation is harnessed for immune activation to synergize with an anti-PD-L1 antibody for the treatment of murine colorectal cancer tumors. The favorable biodistribution and tumor uptake of NCPs and the absence of peripheral neuropathy allow for repeated dosing to afford 100% tumor eradication. The involvement of innate and adaptive immune systems elicit strong and long lasting antitumor immunity which prevents tumor formation when cured mice are challenged with cancer cells. The intrinsically biodegradable, well tolerated, and systemically available immunostimulatory NCP promises to enter clin. testing as an immunotherapy against colorectal cancer.

Epidemiol. studies have consistently linked exposure to PM2.5 with adverse health effects. The oxidative potential (OP) of aerosol particles has been widely suggested as a measure of their potential toxicity. Several acellular chem. assays are now readily employed to measure OP; however, uncertainty remains regarding the atm. conditions and specific chem. components of PM2.5 that drive OP. A limited number of studies have simultaneously utilized multiple OP assays with a wide range of concurrent measurements and investigated the seasonality of PM2.5 OP. In this work, filter samples were collected in winter 2016 and summer 2017 during the atm. pollution and human health in a Chinese megacity campaign (APHHBeijing), and PM2.5 OP was analyzed using four acellular methods: ascorbic acid (AA), dithiothreitol (DTT), 2,7- dichlorofluorescin/hydrogen peroxidase (DCFH) and ESR spectroscopy (EPR). Each assay reflects different oxidising properties of PM2.5, including particle-bound reactive oxygen species (DCFH), superoxide radical production (EPR) and catalytic redox chem. (DTT/AA), and a combination of these four assays provided a detailed overall picture of the oxidising properties of PM2.5 at a central site in Beijing. Pos. correlations of OP (normalized per volume of air) of all four assays with overall PM2.5 mass were observed, with stronger correlations in winter compared to summer. In contrast, when OP assay values were normalized for particle mass, days with higher PM2.5 mass concentrations (μgm-3) were found to have lower mass-normalized OP values as measured by AA and DTT. This finding supports that total PM2.5 mass concentrations alone may not always be the best indicator for particle toxicity. Univariate anal. of OP values and an extensive range of addnl. measurements, 107 in total, including PM2.5 composition, gas-phase composition and meteorol. data, provided detailed insight into the chem. components and atm. processes that determine PM2.5 OP variability. Multivariate statistical analyses highlighted associations of OP assay responses with varying chem. components in PM2.5 for both mass- and volume-normalized data. AA and DTT assays were well predicted by a small set of measurements in multiple linear regression (MLR) models and indicated fossil fuel combustion, vehicle emissions and biogenic secondary organic aerosol (SOA) as influential particle sources in the assay response. Mass MLR models of OP associated with compositional source profiles predicted OP almost as well as volume MLR models, illustrating the influence of mass composition on both particle-level OP and total volume OP. Univariate and multivariate anal. showed that different assays cover different chem. spaces, and through comparison of mass- and volume-normalized data we demonstrate that mass-normalized OP provides a more nuanced picture of compositional drivers and sources of OP compared to volume-normalized anal. This study constitutes one of the most extensive and comprehensive composition datasets currently available and provides a unique opportunity to explore chem. variations in PM2.5 and how they affect both PM2.5 OP and the concentrations of particlebound reactive oxygen species.

In this study, we fabricated four new photobase generating monomers, in which carbamate units functioned as the photobase generating moieties, methacrylate units served as the polymerizable groups and four different groups, succinimido, camphorquinone 3-oximino, di-2-thienyl ketoximino and difuril dioximino units, acted as photosensitive species. The effect of different photosensitive species on the photochem. behavior of the monomers was investigated in detail. The results demonstrate that, among the four monomers, succinimido methacryloxyethyl carbamate (SMC) exhibits the most stable photobase generating property. Furthermore, a copolymer containing SMC is used for a fluorescence imaging material.

Voltage imaging with fluorescent indicators offers a powerful complement to traditional electrode or Ca2+-imaging approaches for monitoring elec. activity. Small mol. fluorescent indicators present the unique opportunity for exquisite control over mol. structure, enabling detailed investigations of structure/function relationships. In this paper, we tune the conjugation between aniline donors and aromatic π systems within the context of photoinduced electron transfer (PeT) based voltage indicators. We describe the design and synthesis of four new voltage-sensitive fluorophores (VoltageFluors, or VFs). Three of these dyes have higher relative voltage sensitivities (ΔF/F) than the previously-reported indicator, VF2.1.Cl. We pair these new indicators with existing VFs to construct a library of voltage indicators with varying degrees of conjugation between the aniline nitrogen lone pair and the aromatic π system. Using a combination of steady-state and time-resolved fluorescence spectroscopy, cellular electrophysiol., fluorescence lifetime imaging microscopy (FLIM), and functional imaging in mammalian neurons and human cardiomyocytes, we establish a detailed link between the photophys. properties of VF dyes and their ability to report on membrane potential dynamics with high signal-to-noise. Anilines with intermediate degrees of conjugation to the aromaticπ system experience intermediate rates of PeT and possess the highest absolute voltage sensitivities. Measured using FLIM in patch-clamped HEK cells, we find that the absolute voltage sensitivity of fluorescence lifetime (Δτfl per mV), coupled with traditional fluorescence intensity-based metrics like ΔF/F and signal-to-noise ratio (SNR), provides a powerful method to both predict and understand indicator performance in cellular systems.

Organic anion transporting polypeptide 1B1 (OATP1B1) is a key hepatic uptake transporter whose inhibition could lead to adverse drug-drug and drug-food interactions. Flavonoids are widely distributed in food and beverages and thus our bodies are frequently exposed to them. Therefore, investigation of the interactions between OATP1B1 and flavonoids could be of great significance. In the present study, 25 common flavonoids were investigated for their interactions with OATP1B1 using the fluorescent substrate 2′,7′-dichlorofluorescein (DCF) and three-dimensional quant. structure-activity relationship (3D-QSAR) anal. Kinetic study showed that OATP1B1-mediated DCF uptake exhibited a monophasic saturation kinetics with a Km value of 9.7 ± 2.4 μM. Inhibition assay for flavonoids on OATP1B1-mediated DCF uptake was performed and their IC50 values were determined upon which reliable and predictive CoMFA (q2 = 0.604, r2 = 0.841) and CoMSIA (q2 = 0.534, r2 = 0.807) models were developed. Our exptl. and computational results showed that flavonoid aglycons interacted with OATP1B1 much stronger than their glycosides such as 3-O- and 7-O-glycosides as bulky hydrophilic and hydrogen-bond forming substituents at C-3 and C-7 positions on rings A and C were unfavorable for their binding. On the other hand, the presence of hydrogen-bond forming groups on ring B was beneficial as long as the number of hydroxyl groups was not >2. Our results also indicated that flavones usually interacted with OATP1B1 much stronger than their 3-hydroxyflavone counterparts (flavonols). The obtained information and 3D-QSAR models could be useful for elucidating and predicting the interactions between flavonoids and human OATP1B1.

In this study, we investigated the effects of the four kinds of derivatization reagents, including fluorescamine, o-phthaladehyde, fluorescein isothiocyanate isomer and 2,3-naphthalenedicarboxaldehyde. A high performance liquid chromatog. with fluorescence detection method for the rapid determination of 16 sulfonamide residues in beef was developed by using improved QuEChERS method for sample pretreatment and fluorescamine for online post-column derivatization. The beef samples were extracted with acetonitrile containing 1% (volume/volume) acetic acid, cleaned-up by QuEChERS method, injected for online post-column derivatization with fluorescamine, and then analyzed with fluorescence detection. Under the optimized conditions of QuEChERS and chromatog., the 16 sulfonamide residues showed good linearities in the range of 0.024-2.533 mg/L with the correlation coefficients (γ) higher than 0.992. The limits of detection of the method were 1.6 to 8.2 μg/kg. The average recoveries of the 16 sulfonamide residues were in the range of 66.6%-109.5% with the relative standard deviations from 0.9% to 9.9%. The method has the advantages of rapidity, simplicity, high sensitivity and better purification effect. It is suitable for the rapid determination of the sulfonamide residues in beef. In the experiment, the researchers used many compounds, for example, 4-Phenyl-3H,3’H-spiro[furan-2,1′-isobenzofuran]-3,3′-dione (cas: 38183-12-9Category: benzofurans).

4-Phenyl-3H,3’H-spiro[furan-2,1′-isobenzofuran]-3,3′-dione (cas: 38183-12-9) belongs to benzofurans derivatives. Many natural or synthetic compounds containing benzofuran skeletons have been found to possess remarkable activity as agrochemicals and pharmaceuticals. Substituted benzofurans find applications such as fluorescent sensors, oxidants, in drug discovery, and in another field of chemistry and agriculture.Category: benzofurans
