  The large body of structural knowledge that is currently available for CRM1 has contributed to atomic level and mechanistic understanding of many steps in the CRM1 nuclear export cycle. However, structural analysis could still inform on several outstanding questions and guide future discoveries pert

  Previous studies demonstrated that cPLA2α translocates to the phagosomal membrane during macrophage phagocytosis through mechanisms that, in humans, involve phosphorylation of the enzyme by c-Jun N-terminal kinases and membrane association via the cationic cluster of four lysine residues present at

  2020-04-09

  

  In general, cellular senescence is considered a programmed response to stress that can be activated by oxidative stress, irradiation or action of substances or drugs. These stressors cause DNA damage and, through the action of specific proteins (p53 and p21), lead to cell senescence (di Fagagna, 200

  In 2015–2016, half a century after its first biochemical characterization as a template-independent polymerase, it was shown that TdT can, firstly, assemble a DNA synapsis by itself, optimally with one micro-homology base-pair between strands [] and secondly, perform a template-dependent nucleotid

  Protein expression and purification. A 3 mL overnight culture of E. coli BL21 (DE3) pLysS pGEX-6P-3-A1S_0222 was grown in Luria-Bertani (LB)-Medium (10 g/L tryptone, 5 g/L yeast extract, 5 g/L NaCl, pH 7.4, 100 μg/mL Amp) at 37 °C and 160 rpm. The overnight culture was diluted 1:100 into 200 mL LB (

  Although the ferromagnetic particles and T4 SR 8278 on the particles were heated by the ac magnetic field, the average temperature of the reaction solution as a whole was kept suitably low for the annealing of DNA ends (16°C). Indeed, no appreciable increase in the temperature of the reaction solut

  In conclusion, we have discovered two new derivatives ( and ) that are potent inhibitors of DHODH. H and C NMR spectroscopic data revealed that these compounds undergo ready isomerisation at room temperature in -DMSO, but the docking studies indicate that there is neither conformation nor configurat

  Introduction Sphingolipids are ubiquitous membrane components of all eukaryotic cells belonging to a group of complex lipids. The basic structure of sphingolipids is composed of a sphingoid long chain base (LCB) linked to a fatty gamma-Glu-Cys via an amide bond to form a ceramide [1]. In animals

  In the present study, we implemented the dendritic RCA-induced formation of amplifying DNAzyme catalytic labels strategy for sensitive and accurate assay of MTase activity and the detection of DNA methylation. In comparison with the traditional RCA process, the proposed strategy achieved high amplif

  It was reported that the expressions of DPP-4 and SDF-1α increase through HIF-1α [27], [28]. Myocardial ischemia by MI enhanced the DPP-4 and SDF-1α levels in myocardium in the present study. SDF-1α is released from cardiomyocytes and has beneficial effects on cardiomyocytes through SDF-1α/CXCR4 aft

  In mammals, ribonucleotide reductase (RNR) is a unique enzyme that catalyzes the rate-limiting step of de novo synthesis of deoxyribonucleoside triphosphates (dNTPs).7, 8 Mammalian RNR consists of two homodimer subunits: the large catalytic dimer RRM1 and the small regulatory dimer RRM2 or RRM2B.

  A surprising second functional effect was found in culture experiments. Inclusion of LTD4 reduced the frequency of Fas receptor (CD95) expression. Once again, this effect, although modest, was reversed by a cysLT1 receptor antagonist. The biologic significance of this effect or its mechanism remain
