Glucanotransferases that can synthesize cyclo-→6)-α-d-Glcp-(1→6)-α-d-Glcp-(1→6)-α-d-Glcp-(1→6)-α-d-Glcp-(1→ (CI4) from dextran were purified to homogeneity from the culture supernatant of Agreia sp. D1110 and Microbacterium trichothecenolyticum D2006. The molecular mass of both enzymes was estimated to be 86 kDa by SDS-PAGE. The glucanotransferase, named CI4-forming enzyme, from Agreia sp. exhibited the highest activity at pH 6.0 and 40 °C. The enzyme was stable on the pH range of 4.6-9.9 and up to 40 °C. On the other hand, the enzyme from M. trichothecenolyticum exhibited the highest activity at pH 5.7 and 40 °C. The enzyme was stable on the pH range of 5.0-6.9 and up to 35 °C. Both enzymes catalyzed 4 reactions, namely, intramolecular α-1,6-transglycosylation (cyclization), intermolecular α-1,6-transglycosylation, hydrolysis of CI4, and coupling reaction. Furthermore, the CI4-forming enzyme produced CI4 from α-1,6-linked glucan synthesized from starch by 6-α-glucosyltransferase. These findings will enable the production of CI4 from starch.Persimmon peels, though usually discarded, are useful sources of nutraceuticals. In this study, persimmon peel-derived pomolic acid was found to suppress the increase in the activity of glycerol-3 phosphate dehydrogenase, a neutral fat synthesis-related enzyme, in 3T3-L1 adipocytes, whereas oleanolic and ursolic acids did not exert this effect. Therefore, persimmon peel may be an effective functional food material.There are only a few combinations of antifungal drugs with known resistance marker genes in the Aspergillus species; therefore, the transformation of their wild-type strains is limited. In this study, to develop the novel dominant selectable marker for itraconazole, a fungal cell membrane synthesis inhibitor, we focused on Aspergillus luchuensis cyp51A (Alcyp51A), which encodes a 14-α-sterol demethylase related to the steroid synthesis pathway. We found that the G52R mutation in AlCyp51A and the replacement of the native promoter with a high-expression promoter contributed to itraconazole resistance in Aspergillus oryzae, designated as itraconazole resistant gene (itrA). The random integration in the A. luchuensis genome of the itrA marker cassette gene also allowed for transformation using itraconazole. Therefore, we succeed in developing a novel itraconazole resistance marker as a dominant selectable marker for transformation in A. oryzae and A. luchuensis.Plants have developed various self-defense systems to survive many types of unfavorable conditions. Heat shock (HS) treatment, an abiotic stress, activates salicylic acid (SA) biosynthesis to enhance resistance to biotic stresses in some plant species. Since SA is produced from the shikimate pathway, other related metabolic pathways were expected to be upregulated by HS treatment. We speculated that tocopherol biosynthesis utilizing chorismic acid would be activated by HS treatment. In Arabidopsis, expression analysis of tocopherol biosynthetic genes, HPPD, VTE2, VTE3, VTE1, and VTE4, in combination with measurement of metabolites, indicated that HS treatment enhanced the biosynthesis and accumulation of tocopherols. Analyses using an SA biosynthesis-deficient mutant indicated that the upregulation of tocopherol biosynthesis was independent of the SA-mediated signaling pathway.Long noncoding RNAs have been implicated in many biological processes, but their roles in liver regeneration still need to be illustrated. Therefore, we aimed to investigate the role of LINC00265 as a pivotal regulator of hepatocyte proliferation during liver regeneration. It was found that LINC00265 is significantly upregulated in rat liver tissues at various time points after 2/3 liver resection. LINC00265 knockdown inhibited hepatocyte proliferation, induced cell apoptosis and led to G2/M phase cell cycle arrestment.  https://www.selleckchem.com/products/oxidopamine-hydrobromide.html  In rats subjected to surgery, LINC00265 knockdown decreased liver/body weight ratio, attenuated improvement from liver damage and reduced Ki67 and PCNA expression. Luciferase reporter assays confirmed that miR-28-5p was a direct target of LINC00265, and inhibition of miR-28-5p abolished the effect of LINC00265 knockdown. In summary, LINC00265 might maintain hepatocyte proliferation by targeting miR-28-5p during liver regeneration and should be considered as a promising therapeutic option for hepatocyte regeneration after liver resection.Vitamin C has re-emerged as a promising anticancer agent. This study attempts to analyze the differential gene expression of profiles GSE11919 to look for some clues, and the most significant cell cycle pathway caused by vitamin C was identified by integrated bioinformatics analysis. Inspired by this, we investigated the effect of vitamin C treatment on gastric carcinoma cells by detection of cell cycle, apoptosis, and autophagy. Vitamin C significantly elevated the percentage of cells at G0/G1 phase, whereas the percentage of S phase cells was decreased. Meanwhile, vitamin C treatment resulted in downregulation of cell cycle-related protein Cyclin D1. We deduced that the downregulation of Cyclin D1 by vitamin C accompanied by significantly increased 5'AMP-activated protein kinase and induced autophagy in MKN45 cells. These results suggest that vitamin C has the antiproliferation effect on gastric carcinoma cells via the regulation of cell cycle and autophagy by Cyclin D1.In Saccharomyces cerevisiae, Avt4 exports neutral and basic amino acids from vacuoles. Previous studies have suggested that the GATA transcription factors, Gln3 and Gat1, which are key regulators that adapt cells in response to changes in amino acid status, are involved in the AVT4 transcription. Here, we show that mutations in the putative GATA-binding sites of the AVT4 promoter reduced AVT4 expression. Consistently, a chromatin immunoprecipitation (ChIP) assay revealed that Gat1-Myc13 binds to the AVT4 promoter. Previous microarray results were confirmed that gln3∆gat1∆ cells showed a decrease in expression of AVT1 and AVT7, which also encode vacuolar amino acid transporters. Additionally, ChIP analysis revealed that the AVT6 encoding vacuolar acidic amino acid exporter represents a new direct target of the GATA transcription factor. The broad effect of the GATA transcription factors on the expression of AVT transporters suggests that vacuolar amino acid transport is integrated into cellular amino acid homeostasis.
