The emergence of optochem. approaches has had a diverse impact over a broad range of biol. research due to spatiotemporal regulation. Herein, we integrate this feature into the bioorthogonal chem. reporter strategy, which enables visible light-controlled spatiotemporal labeling of cell-surface glycans, lipids, and proteins. The metabolic precursors were first incorporated into live cells, and next the bioorthogonal reaction converted the azide/alkyne into a photo-active functional group, which allowed for subsequent photo-click reaction. We demonstrated this strategy by specifically labeling sialome, mucin-type O-glycome, phospholipids and newly-synthesized membrane proteins, resp. The sequential photoirradiation-orthogonal reporter tagging (SPORT) should facilitate the probing of biomols. in complex biol. systems with high spatiotemporal precision.

The relationship between gut microbial dysbiosis and acute or chronic kidney disease (CKD) is still unclear. Here, we show that oral administration of the probiotic Lactobacillus casei Zhang (L. casei Zhang) corrected bilateral renal ischemia-reperfusion (I/R)-induced gut microbial dysbiosis, alleviated kidney injury, and delayed its progression to CKD in mice. L. casei Zhang elevated the levels of short-chain fatty acids (SCFAs) and nicotinamide in the serum and kidney, resulting in reduced renal inflammation and damage to renal tubular epithelial cells. We also performed a 1-yr phase 1 placebo-controlled study of oral L. casei Zhang use (Chinese clin. trial registry, ChiCTR-INR-17013952), which was well tolerated and slowed the decline of kidney function in individuals with stage 3-5 CKD. These results show that oral administration of L. casei Zhang, by altering SCFAs and nicotinamide metabolism, is a potential therapy to mitigate kidney injury and slow the progression of renal decline.

Ugawa, Tohru; Kurihara, Kenzo published the artcile< Enhancement of canine taste responses to umami substances by salts>, Category: alcohols-buliding-blocks, the main research area is taste umami substance dog salt type; MSG taste dog salt type; GMP taste dog salt type.

The effects of salts on canine taste responses to umami substances were examined by recording the activity of the chorda tympani nerve. The responses to monosodium glutamate (MSG), disodium 5′-guanylate (GMP), and that induced by the synergism between MSG and GMP were enhanced by the presence of various salts. The effective salts were those carrying inorganic cations such as Na, K, and Mg, while CaCl2 had no enhancing effect. Salts carrying organic cations such as tris(hydroxymethyl)aminomethane (Tris), choline, N-methyl-D-glucamine, and 1,3-bis[tris(hydroxymethyl)methylamino]propane also produced pos. results. The dependence of the umami responses on NaCl and MgCl2 concentrations showed a bell-shaped response curve with the maximal enhancing effect being seen at 100 mM NaCl and 3-10 mM MgCl2. The degree of the enhancement depended not only on the species of the cation, but also on that of anion. For example, 100 mM NaCl showed a much larger enhancing effect than Na phosphate, Na2SO4, and Na4Fe(CN)6 at equimolar Na. The enhancing effects of salts on the responses to the umami substances could not be simply explained in terms of the permeability of cation and anion of salts. It was speculated that the binding of both cations and anions to the receptor membranes leads to changes in the interaction of the umami substances with the receptor proteins.

Fontaine, Fanny; Hequet, Arnaud; Voisin-Chiret, Anne-Sophie; Bouillon, Alexandre; Lesnard, Aurelien; Cresteil, Thierry; Jolivalt, Claude; Rault, Sylvain published the artcile< First identification of boronic species as novel potential inhibitors of the Staphylococcus aureus NorA efflux pump>, Recommanded Product: 2-Methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine, the main research area is boron compound transport protein NorA Staphylococcus.

Overexpression of efflux pumps is an important mechanism of bacterial resistance that results in the extrusion of antimicrobial agents outside the bacterial cell. Inhibition of such pumps appears to be a promising strategy that could restore the potency of existing antibiotics. The NorA efflux pump of Staphylococcus aureus confers resistance to a wide range of unrelated substrates, such as hydrophilic fluoroquinolones, leading to a multidrug-resistance phenotype. Here, 150 heterocyclic boronic species were evaluated for their activity against susceptible and resistant strains of S. aureus. Twenty-four hit compounds, although inactive when tested alone, were found to potentiate ciprofloxacin activity by a 4-fold increase at concentrations ranging from 0.5 to 8 μg/mL against S. aureus 1199B, which overexpresses NorA. Boron-free analogs showed no biol. activity, thus revealing that the boron atom is crucial for biol. activity. This work describes the first reported efflux pump inhibitory activity of boronic acid derivatives

Zingiberis Rhizoma (ZR) has nutritional value and application potentiality, while Zingiberis Rhizoma Praeparatum (ZRP) and Carbonised Ginger (CG) are two main processed products of ZR based on different methods. Here, we performed a widely targeted metabolomics method with Sequential Windowed Acquisition of all Theor. fragment ions (SWATH) mode to analyze differential metabolites in ZR, ZRP and CG. Addnl., the chem. derivatization was applied to characterize different submetabolomes and improve the separation effect and MS response of metabolites. In total, 369 metabolites were identified and divided into 14 categories, 104 of which were differential metabolites. Our results suggest that carbohydrates, nucleotides, organic acids, vitamins, lipids, indoles, alkaloids, and terpenes contributed to a downward trend after processing, but the maximum content of flavanones, phenylpropanes and polyphenols appeared in ZRP, and that of alcs. appeared in CG. These findings serve as promising perspectives for developing functional food in ZR, ZRP and CG.

Zhou, Sha; Wang, Jieying; Chen, Lan; Wang, Jun; Zhao, Fazhu published the artcile< Microbial community structure and functional genes drive soil priming effect following afforestation>, Synthetic Route of 87-73-0, the main research area is soil microorganism carbon afforestation biodegradation gene enzyme metagenome; (13)C-glucose labeling; Afforestation; Metagenomic sequencing; Microbial function; Stable C.

Afforestation substantially modifies native soil organic carbon (SOC) decomposition via plant carbon inputs (the priming effect), and in turn, triggers vital biogeochem. processes that influence the regulation of soil carbon dynamics. Soil microbes are crucial in regulating the direction and magnitude of the priming effect. In the present study, we performed metagenomic sequencing and 13C-glucose labeling analyses of microbial communities and priming effects across a Robinia pseudoacacia afforestation chronosequence (14-, 20-, 30-, and 45-yr-old stands) in the Loess Plateau in China, with adjacent farmland being selected as a control. Our results revealed that the cumulative priming effect across five sites along the afforestation chronosequence initially increased and approached a peak value in the 20-yr-old stand, after which it declined. The priming effect was predominantly driven by the microbial community structure (i.e., the fungal-to-bacterial ratios and relative abundances of Proteobacteria and Actinobacteria), and stable C decomposition genes and C-degrading enzymes. Specifically, among the key functional genes correlated with priming effect, which were identified in orders Rhizobiales and Pseudonocardiales, considerably promoted SOC priming. Overall, our findings indicate that afforestation alters soil microbial community structure and function, particularly with respect to enhancing stable soil C decomposition genes, which may promote SOC priming. The findings of the present study could enhance our understanding of fresh C input-induced changes associated with C mineralization in the context of the revegetation of ecol. fragile areas. The sequencing data have been deposited into the NCBI database with the accession number SRP319300.

Yuan, Li; Zhou, Mengmeng; Huang, Dawei; Wasan, Harpreet S; Zhang, Kai; Sun, Leitao; Huang, Hong; Ma, Shenglin; Shen, Minhe; Ruan, Shanming published the artcile< Resveratrol inhibits the invasion and metastasis of colon cancer through reversal of epithelial‑ mesenchymal transition via the AKT/GSK‑3β/Snail signaling pathway.>, Quality Control of 501-36-0, the main research area is .

The identification of safe and effective drugs that inhibit tumor invasion and metastasis is required to improve the clinical outcome of patients with colon cancer. The present study aimed to investigate the inhibitory effects and possible mechanisms of action of resveratrol against the invasion and metastasis of colon cancer. AKT1‑knockdown SW480 and SW620 colon cancer cells were used to detect the effects of resveratrol on cell invasion and metastasis, as well as changes in the expression of epithelial‑mesenchymal transition (EMT) markers and serine/threonine kinase (AKT)/glycogen synthase kinase (GSK)‑3β/Snail signaling pathway‑related molecules in vitro. Furthermore, nude mice were inoculated with SW480 cells in the tail vein to establish an in vivo lung metastasis model of colon cancer, to investigate the effects of resveratrol on lung metastasis in colon cancer. The results revealed that resveratrol treatment and AKT1 knockdown significantly inhibited cell migration and invasion in colon cancer, and markedly increased E‑cadherin expression and decreased that of N‑cadherin, phospho (p)‑AKT1, p‑GSK‑3β, and Snail in colon cancer both in vitro and in vivo. Furthermore, the effects of resveratrol were significantly weaker in the AKT1‑knockdown cells. In conclusion, resveratrol may suppress the invasion and metastasis of colon cancer through reversal of EMT via the AKT/GSK‑3β/Snail signaling pathway. AKT1 may therefore be a key regulator of EMT in colon cancer cells and a potential therapeutic target for this disease.

Mounting evidence indicates the key role of nitrogen (N) on diverse processes in plant, including development and defense. Using a combined transcriptomics and metabolomics approach, we studied the response of seedlings to N starvation of two different tetraploid wheat genotypes from the two main domesticated subspecies: emmer and durum wheat. We found that durum wheat exhibits broader and stronger response in comparison to emmer as seen from the expression pattern of both genes and metabolites and gene enrichment anal. They showed major differences in the responses to N starvation for transcription factor families, emmer showed differential reduction in the levels of primary metabolites while durum wheat exhibited increased levels of most of them to N starvation. The correlation-based networks, including the differentially expressed genes and metabolites, revealed tighter regulation of metabolism in durum wheat in comparison to emmer. We also found that glutamate and γ-aminobutyric acid (GABA) had highest values of centrality in the metabolic correlation network, suggesting their critical role in the genotype-specific response to N starvation of emmer and durum wheat, resp. Moreover, this finding indicates that there might be contrasting strategies associated to GABA and glutamate signaling modulating shoot vs. root growth in the two different wheat subspecies.

Schulz, Patrick; Dueck, Benjamin; Mourot, Alexandre; Hatahet, Lina; Fendler, Klaus published the artcile< Measuring ion channels on solid supported membranes>, Reference of 35564-86-4, the main research area is measurement ion channel solid supported membrane.

Application of solid supported membranes (SSMs) for the functional investigation of ion channels is presented. SSM-based electrophysiol., which has been introduced previously for the investigation of active transport systems, is expanded for the anal. of ion channels. Membranes or liposomes containing ion channels are adsorbed to an SSM and a concentration gradient of a permeant ion is applied. Transient currents representing ion channel transport activity are recorded via capacitive coupling. The authors demonstrate the application of the technique to liposomes reconstituted with the peptide cation channel gramicidin, vesicles from native tissue containing the nicotinic acetylcholine receptor, and membranes from a recombinant cell line expressing the ionotropic P2X2 receptor. It is shown that stable ion gradients, both inside as well as outside directed, can be applied and currents are recorded with an excellent signal/noise ratio. For the nicotinic acetylcholine receptor and the P2X2 receptor excellent assay quality factors of Z’ = 0.55 and Z’ = 0.67, resp., are obtained. This technique opens up new possibilities in cases where conventional electrophysiol. fails like the functional characterization of ion channels from intracellular compartments. It also allows for robust fully automatic assays for drug screening.

Dyck, Garrison J. B.; Raj, Pema; Zieroth, Shelley; Dyck, Jason R. B.; Ezekowitz, Justin A. published the artcile< The effects of resveratrol in patients with cardiovascular disease and heart failure: a narrative review>, Application In Synthesis of 501-36-0 , the main research area is review resveratrol cardioprotectant cardiovascular disease heart failure; CVD; heart failure; resveratrol.

A review. Cardiovascular disease (CVD) is the main cause of death globally and responsible for the second highest number of deaths in Canada. Medical advancements in the treatment of CVD have led to patients living longer with CVD but often progressing to another condition called heart failure (HF). As a result, HF has emerged in the last decade as a major medical concern. Fortunately, various “”traditional”” pharmacotherapies for HF exist and have shown success in reducing HF-associated mortality. However, to augment the treatment of patients with CVD and/or HF, alternative pharmacotherapies using nutraceuticals have also shown promise in the prevention and treatment of these two conditions. One of these natural compounds considered to potentially help treat HF and CVD and prevent their development is resveratrol. Herein, we review the clin. findings of resveratrol’s ability to be used as an effective treatment to potentially help treat HF and CVD. This will allow us to gain a more fulsome appreciation for the effects of resveratrol in the health outcomes of specific patient populations who have various disorders that constitute CVD.
