  2019-11-12

  

  Another potential source of variable affinities is inherent in the method of RBA determination. While several reports simply use relative IC50 values as RBAs [11], [12], [13], [14], [15], these are only an approximate measure of relative affinity since IC50 varies due to experimental and biological

  2019-11-12

  

  O-GlcNAc transferase OGT belongs to the metal-independent GT-B superfamily of glycosyltransferases, which has been well-reviewed previously [14,15]. OGT is an essential gene encoded on the X-chromosome, and it has two main regions: a long N-terminal tetratricopeptide repeat (TPR) region and a C-t

  2019-11-12

  

  The ultrafiltration approach has been used to measure equilibrium BIEs for a number of enzyme systems, including psoralen mg hexokinase (Lewis and Schramm, 2003a, Lewis and Schramm, 2003b), thymidine phosphorylase (Birck & Schramm, 2004), purine nucleoside phosphorylase (Murkin, Tyler, & Schramm, 2

  2019-11-12

  

  To explore the mechanism behind differential activation kinetics, Marcott et al. (2018) manipulate local dopamine dynamics. They show that differences in dopamine concentrations are not responsible for different D2R activation kinetics, since D2-IPSCs reach similar amplitudes at different rates in N

  2019-11-12

  

  Then what is the solution to tackle DNA damage-induced metabolic decline? The culprit here may be not DNA damage signaling per se, but rather the persistent activation of the DNA damage signaling pathways due to age-related accumulation of DNA damage. DNA repair, including repair by NHEJ, is an esse

  2019-11-12

  

  Here we investigate in more detail how Dot1 function contributes to the regulation of DNA damage tolerance. We find that Dot1 modulates the response to the alkylating agent MMS through its catalytic activity on H3K79. In fact, progressively reduced levels of H3K79 tri-methylation result in gradually

  2019-11-12

  

  Besides chemopreventive effects against oxidative DNA damage we evaluated the protective effects of the three Hypericum sp. and isolated compounds against alkylating DNA damage induced by MMS in HT29 cells. Human exposure to alkylating agents, from different sources, occurs in a continuous way and i

  2019-11-12

  

  In patients with CTEPH, ET-1 levels are raised and have been shown to fall after PEA surgery [24]. After an acute pulmonary embolism there is obstruction of the pulmonary TH287 receptor by acute thrombus and elevated levels of ET-1 [28], [30]. Elevated levels of ET-1 have also been observed in air e

  Previously, to detect CDKL5 activity, we used a radioactive phosphorylation assay with amphiphysin 1 protein as a substrate [,,]. However, it is necessary to establish a safe and rapid method for analyzing CDKL5 mutant activity. Here, we report a new method for investigating autophosphorylation acti

  The observed increase in Bdnf1 mRNA occurred 1 h after treatment indicates participation of BDNF in early plasticity and subsequently mnemonic processes. Most of the evidence regarding the importance of BDNF for memory formation derived from electrophysiological studies that utilized the molecular c

  2019-11-11

  

  Agonist binding ETA activation is promoted by binding of the endogenous peptidergic agonists to their orthosteric binding site on the receptor. ET1 and ET2 (Trp6-Leu7-ET1) bind with equal high affinity to ETA, whereas the third endogenous isopeptide ET3 (Thr2-Phe4-Thr5-Tyr6-Lys7-Tyr14-ET1) binds

  Structural characterization of A1S_0222. Given the low specific activity of our protein preparations and the considerable problems to concentrate the protein to levels above 2.5 mg/mL, we employed SAXS to structurally characterize and generate a low-resolution model of A1S_0222 in solution.

  In laboratory strains of Escherichia coli, three mechanisms of repair for alkylated bases are known. The first involves constitutively expressed Ogt and inducible Ada methyltransferases, directly removing methyl groups from O6-methylguanine (O6meG) and O4-methylthymine (O4meT) [1], [2], [3], [4].
