Renal tubular epithelial cell (TEC) injury and fibrosis are the key factors of the pathogenesis of chronic kidney disease. Here, we reported that tectorigenin is effectively protected against obstructive nephropathy established by unilateral ureteral obstruction (UUO). In vivo, tectorigenin administration significantly alleviated the deteriorations of renal functions including blood urea nitrogen and creatinine. Meanwhile, results from the histol. suggested that renal injury characterized by tubular cell damage and fibrosis lesions of kidneys in UUO group were markedly attenuated following tectorigenin treatment. Mechanistically, we found that tectorigenin treatment greatly inhibited Smad3 phosphorylation, and the transcription and protein level of Nox4, a newly identified direct downstream mol. of Smad3 and a modulator of ferroptosis, while it indirectly restored the expression of glutathione peroxidase 4, a neg. regulator of ferroptosis. Consistent with in vivo studies, treatment with tectorigenin also suppressed the ferroptosis induced by erastin/RSL3 and fibrosis stimulated by transforming growth factor β1 (TGF-β1) in primary renal TECs. What is more, treatment with ferroptosis inhibitor, ferrostatin-1, also impeded TGF-β1 stimulated the profibrotic effects in TECs, indicating that tectorigenin may relieve fibrosis by inhibiting ferroptosis in TECs. In addition, tectorigenin treatment exhibited a similar tendency, which inhibited Smad3 activation, and the docking anal. revealed that tectorigenin docked well into the Smad3 binding cavity with strong binding affinity (-7.9 kcal/mol). Thus, this study deciphers the protective effect of tectorigenin against obstructive nephropathy through inhibiting Smad3-mediated ferroptosis and fibrosis.

A series of 2,7-disubstituted thieno[3,2-d]pyrimidine derivatives I [R1 = 2-methoxy, 3-acetyl, 3-methylsulfonyl, etc.], II [R2 = methylcarbamoyl, piperidine-3-carbonylamino, diethoxyphosphorylmethyl, etc.], III [R3 = H, Me, ethoxy, etc.; R4 = H, fluoro, methyl; R5 = H, fluoro] and IV [R6 = pyrrolidin-3-yl, tetrahydro-2H-pyran-4-yl, piperidin-3-ylmethyl, etc.] were synthesized and evaluated as novel focal adhesion kinase (FAK) inhibitors. The novel 2,7-disubstituted thieno[3,2-d]pyrimidine scaffold was designed as a new kinase inhibitor platform that mimics the bioactive conformation of the well-known diaminopyrimidine motif. Most of the compounds potently suppressed the enzymic activities of FAK and potently inhibited the proliferation of U-87MG, A-549 and MDA-MB-231 cancer cell lines. Among these derivatives, the optimized compound III [R3 = R5 = H, R4 = fluoro] potently inhibited the enzyme (IC50 = 28.2 nM) and displayed stronger potency than TAE-226 in U-87MG, A-549 and MDA-MB-231 cells, with IC50 values of 0.16, 0.27, and 0.19μM, resp. Compound III [R3 = R5 = H, R4 = fluoro] also exhibited relatively less cytotoxicity (IC50 = 3.32μM) toward a normal human cell line, HK2. According to the flow cytometry results, compound III [R3 = R5 = H, R4 = fluoro] induced the apoptosis of MDA-MB-231 cells in a dose-dependent manner and effectively arrested MDA-MB-231 cells in G0/G1 phase. Further investigations revealed that compound III [R3 = R5 = H, R4 = fluoro] potently suppressed the migration of MDA-MB-231 cells. Collectively, these data support the further development of compound III [R3 = R5 = H, R4 = fluoro] as a lead compound for FAK-targeted anticancer drug discovery.

Fatty acid composition is an important aspect of meat quality in ruminants. Improving the beneficial fatty acid level in cashmere goat meat is important to its economic value. To investigate microRNAs (miRNAs) and mRNAs that regulate or coregulate polyunsaturated fatty acid (PUFA) synthesis and metabolism in the Inner Mongolia cashmere goat, we used longissimus dorsi muscle (WLM) and biceps femoris muscle (WBM) for transcript-level sequencing. RT-qPCR was used to evaluate the expression of mRNAs and miRNAs associated with PUFA synthesis and metabolism The total PUFA content in the WBM was significantly higher than that in the WLM (P < 0.05). Our study is the first to systematically report miRNAs in cashmere goat meat. At the mRNA level, 20,375 genes were identified. ACSL1, CD36 and TECRL were at the center of a gene regulatory network and contributed significantly to the accumulation and metabolic regulation of fatty acids. At the miRNA level, 426 known miRNAs and 30 novel miRNAs were identified. KEGG anal. revealed that the miRNA target genes were involved mainly in the PPAR signaling pathway. The mRNA-miRNA coregulation anal. showed that ACSL1 was neg. targeted by nine miRNAs: chi-miR-10a-5p, chi-miR-10b- 5p, chi-miR-130b-5p, chi-miR-15a-5p_R-1, chi-miR-15b-5p, chi-miR-16a-5p, chi-miR- 16b-5p, chi-miR-181c-5p_R+1, and chi-miR-26b-5p. Finally, we speculated that the simultaneous silencing of ACSL1 by one or more of these nine miRNAs through PPAR signaling led to low ACSL1 expression in the WLM and, ultimately to high PUFA content in the WBM. Our study helps elucidate the metabolic regulation of fatty acids in Inner Mongolia cashmere goats.

The present work investigates the proficiency of green silver oxide nanocatalyst synthesized from Monotheca buxifolia (Falc.) Dcne. leaves extract, and their application for biodiesel synthesis from novel Prunus bokhariensis seed oil (non-edible). The seed oil content of 55% and FFA content of 0.80 mg KOH/g were reported. Several anal. tools (EDX, FT-IR, SEM and XRD) were used to characterize the Ag2O nanocatalyst. Maximum (89%) FAME yield of the PBSOB (Prunus bokhariensis seed oil biodiesel) was achieved at ambient transesterification conditions i.e. 3.5 wt% nanocatalyst loading, 2.5 h reaction time, 130°C of reaction temperature and 12:1 alc. to oil ratio. The synthesized PBSOB was addnl. characterised by anal. methods like, GC-MS and FT-IR. The different aspects of fuel were identified i.e. flash point (84°C), kinematic viscosity (4.01 cSt @ 40°C), sulfur content (0.0003 wt %), d. (0.853 kg/L) and acid number (0.167 mg KOH/g). All the above properties were verified and agreed well with biodiesel international standards (European Union (14214)), China GB/T (20828) and ASTM (6751, 951). In general, Prunus bokhariensis seed oil and Ag2O nanocatalyst seem to be remarkably active, cheap and stable candidates for the biodiesel industry in future.

Geahlen, Robert L.; Loudon, G. Marc; Paige, Lisa A.; Lloyd, David published the artcile< A general method for preparation of peptides biotinylated at the carboxy terminus>, HPLC of Formula: 112-63-0, the main research area is biotinylated peptide C terminus; Merrifield synthesis biotinylated peptide.

A method for the preparation of a biotinylated resin that can be elongated by standard methods of solid-phase peptide synthesis to give peptides biotinylated at the carboxy terminus is described. This methodol. is particularly important for the preparation of biotinylated peptides in which a free amino terminus is required. Coupling of Nε-9-fluorenylmethoxycarbonyl(Fmoc)-Nα-tert-butyloxycarbonyl(Boc)-L-lysine to p-methylbenzhydrylamine resin, followed by removal of the Fmoc protecting group and reaction with (+)-biotin-4-nitrophenyl ester yielded Nα-Boc-biocytin-p-methylbenzhydrylamine resin. The utility of this resin was tested by the synthesis of a biotinylated peptide, Gly-Asn-Ala-Ala-Ala-Ala-Arg-Arg-biocytin-NH2, for use as an in vitro substrate for myristoyl-CoA:protein N-myristoyltransferase (NMT), the enzyme that catalyzes protein N-myristoylation. Anal. of the peptide derivative by HPLC and mass spectrometry revealed a single major product of the expected mass, indicating that the biotin group survived cleavage and deprotection with HF. The biotinylated peptide served as a substrate for NMT, and the resulting myristoylated peptide could be quant. recovered by adsorption to immobilized avidin.

We investigated the laser photolysis of tetrasodium 1,3,6,8-pyrene-tetrasulfonate (Na4PS4) and sodium 1-pyrenesulfonate (NaPS) in aqueous and reverse micellar solutions The photoproducts as well as their yields were found to strongly depend on the reaction parameters such as pH, dissolved gases and the size of water pool. The primary reaction in aqueous solution was commonly presented by laser-induced formation of the cation radicals followed by hydroxylation of them. In the case of PS44-, pyranine was efficiently and highly selectively formed, possibly via desulfonation of the cation radical, P√+S44-, followed by the hydroxylation. On the other hand, from PS-, hydroxypyrenesulfonate (PSOH) was initially formed in alk. solution and desulfonation occurred secondarily, leading to the formation of hydroxypyrene. These photoreactions were markedly suppressed within a small water pool of the reverse micelle. As the size of water pool increased similar photochem. reactions occurred depending on the dissolved gases. The observed micellar effects could be explained based on the pH of water pool and the nature of the cation radicals in it.

Shift-workers show an increased incidence of type 2 diabetes mellitus (T2DM). A possible mechanism is the disruption of the circadian timing of glucose homeostasis. Skeletal muscle mitochondrial function is modulated by the mol. clock. We used time-restricted feeding (TRF) during the inactive phase to investigate how mistimed feeding affects muscle mitochondrial metabolism Rats on an ad libitum (AL) diet were compared to those that could eat only during the light (inactive) or dark (active) phase. Mitochondrial respiration, metabolic gene expressions, and metabolite concentrations were determined in the soleus muscle. Rats on AL feeding or dark-fed TRF showed a clear daily rhythm in muscle mitochondrial respiration. This rhythm in mitochondrial oxidative phosphorylation capacity was abolished in light-fed TRF animals and overall 24h respiration was lower. The expression of several genes involved in mitochondrial biogenesis and the fission/fusion machinery was altered in light-fed animals. Metabolomics anal. indicated that light-fed animals had lost rhythmic levels of α-ketoglutarate and citric acid. Contrastingly, lipidomics showed that light-fed animals abundantly gained rhythmicity in levels of triglycerides. Furthermore, while the RER shifted entirely with the food intake in the light-fed animals, many measured metabolic parameters (e.g., activity and mitochondrial respiration) did not strictly align with the shifted timing of food intake, resulting in a mismatch between expected metabolic supply/demand (as dictated by the circadian timing system and light/dark-cycle) and the actual metabolic supply/demand (as dictated by the timing of food intake). These data suggest that shift-work impairs mitochondrial metabolism and causes metabolic inflexibility, which can predispose to T2DM.
