  Introduction Biocatalysis can be used to synthesize chiral building blocks, such as monomers for polymer materials, and precursors for pharmaceuticals [[1], [2], [3], [4]]. Enzymes are very suitable for catalyzing reactions with high enantioselectivity to obtain chiral products. For instance, alc

  A series of monocarboxylated chalcones (e.g. compounds 7 and 8, Fig. 2A) was previously identified as good CysLT1 antagonists [20], and none of them exhibited CysLT2 antagonistic activities (Supplementary Table S1). This study was consistent with reported result that CysLT2 BRD4770 for was not sens

  2019-08-02

  

  In a study on the time course of a mechanism-based inactivation of CYP3A by HIV protease inhibitors, Katzenmaier et al. [37] reported that the suppression of CYP3A activity continued for threedays after the discontinuation of ritonavir. In the present study, the CYP3A activity on day 28 after a seve

  2019-08-01

  

  As proof of principle, the effect of selective blockade was measured using TAK-044, a peptide antagonist with approximately 250-fold selectivity for the ETA subtype over ETB as measured by ligand binding in the human heart. A 30-mg infusion over 15 minutes of TAK-044 (providing a serum concentration

  Does a universal mechanism for TLS exist? Our previous studies using the bacteriophage T4 DNA polymerase generated the model provided in Fig. 7 that quantifies the molecular forces influencing key steps in the polymerization pathway during the replication of a non-instructional versus miscoding DNA

  Acknowledgments We are grateful to Dr. Jean-Marie Bernassau for his leadership in establishing our virtual screening platform and Dr. Julie Bick for protein purification. X-ray data collection for compound 4 was performed by Shamrock Structures at Southeast Regional Collaborative Access Team (SER-C

  2019-08-01

  

  Two key enzymes play important roles in the bioconversion of xylitol from d-arabitol, namely d-arabitol dehydrogenase (ArDH) and NADH-dependent xylitol dehydrogenase (XDH), respectively (Qi et al., 2014). In an earlier study, we developed a high xylitol yield strain by expressing xdh in E. coli BL21

• Three DDR binding sites have been mapped

  2019-08-01

  

  Three DDR2 binding sites have been mapped on the collagen triple helix by us for collagen type 1 and by others using the collagen toolkit for collagen type 2. All of the three reported binding sequences are conserved in the α1 chain of collagen types 1, 2 and 3. The central motif sequence GARGQAGVMG

  2019-08-01

  

  We show that direct contact with MSCs is necessary and sufficient to induce DDR2 upregulation in breast cancer cells. DDR2 expression in MSC is required for collagen deposition and leads to increased DDR2 expression and activation in breast cancer cells. This paracrine-autocrine MSC-cancer cell axis

  2019-08-01

  

  Collagen alignment can contribute to tissue stiffening (Malik et al., 2015, Paszek et al., 2005), and ECM stiffness in turn is a powerful activator of integrin function (Levental et al., 2009). These findings highlight the contribution of the mechanical properties of the ECM to signal transduction.

  HEK-293 CB-839 stably transfected with CysLT1 were stimulated with LTD and internalization was studied by confocal microscopy, FACS or cell-surface ELISA. Cells were co-transfected with wildtype and dominant negative (DN) mutants of arrestin and dynamin. Clathrin-mediated endocytosis was investiga

  Another question concerns the mechanism of PC reduction during the phosphate starvation response. There are at least three main mechanisms of PC depletion: suppression of PC synthesis due to substrate exhaustion, downregulation of PC synthase expression by suppression of gene transcription or intens

  Finally, the effect of the [BMIM][BF4] concentration change on the P-T diagram of methane hydrate was predicted using the proposed model. Three various concentrations (including 10%, 15% and 20%) were considered for calculations. The experimental data [49] and modeling results are demonstrated and c

  Adding more pieces to the puzzle, using a human-to-animal crossover study, blood taken from healthy volunteers that underwent exercise was used as a dialysate to perfuse a rabbit heart in a Langendorff model of MI [62]. Unprecedentedly, dialysate of plasma from exercised humans reduced infarct size

  2019-08-01

  

  Despite the differences in the clustering abilities of DDR1b versus DDR2 upon ligand administration, we also noted striking similarities in the spatial distribution and phosphorylation of DDR1b-YFP and DDR2-GFP. We show for the first time that in MC3T3-E1 cells, after 4 h of collagen administration,
