  2019-09-20

  

  Introduction O6-Methylguanine-DNA methyltransferase (MGMT) is a DNA-repair enzyme that specifically transfers alkyl adducts from the O6 position of guanine to the cysteine residue (Cys145) in its active site. In cancer cells, this ability of MGMT disrupts the cytotoxic actions of alkylating antic

  Introduction Cholesterol plays a pivotal role as a constituent of biological membranes and as a precursor for vitamins, hormones and bile acids. Accordingly, its production, distribution, and elimination must be tightly regulated at the cellular and organismal level. Accordingly, dysregulated chole

  2019-09-20

  

  In studies directed toward the development of sequence-specific major-groove binding small Curcumin mass [11], we desired a non-intercalating molecular scaffold that could direct attached moieties into the major groove. As an initial step toward this goal, we wished to study the DNA binding mode a

  2019-09-20

  

  All DGKs have at least two cysteine-rich regions homologous to the C1A and C1B motifs of PKCs [26]. In theory, these domains may bind DAG, perhaps localizing DGKs to where DAG accumulates. However, no DGK C1 domain has so far been conclusively shown to bind DAG. In fact, structural predictions sugge

  Discussion The differences in the kinetic properties of L-AmDH and LeuDH presented herein reflect a different kinetic mechanism. When compared to its parent enzyme, L-AmDH displayed a different substrate binding order, lower affinity for the keto substrate, and stronger product inhibition. The tw

  2019-09-20

  

  Confidence with which data of animal safety/toxicity studies can be translated to human depends upon the knowledge that whether humans would be exposed to similar chemical entities (parent and its metabolites) as the animals exposed during toxicity studies. In this regard, in vitro qualitative evalu

  DDX3 belongs to the DEAD-box family of proteins, ATP-dependent RNA helicases characterized by the presence of a highly conserved helicase core domain [13]. This catalytic core is composed of two RecA-like domains containing motifs involved in ATP binding/hydrolysis, RNA binding and helicase activity

  Our study demonstrates that the duration of storage under the conditions analysed did not have a major effect on the recovery efficiency for any of the swabs (Fig. 1). However, up to 4-fold differences in the recovery efficiencies were observed between the different swabs tested (Fig. 2). Using the

  Here, two labs that helped characterize these two pathways have worked together to further test whether these apparently parallel pathways from β-AR to CaMKII-RyR might be related in series. Much of the work leading to the Epac pathway involved measurement of Ca sparks as an index of SR Ca leak, oft

  Results Discussion The advent of TKI treatment has greatly improved CML therapy. Because CML LSCs are less sensitive to TKIs, CML is usually controlled rather than cured, highlighting an unmet clinical need. Developed from our previous finding that CML LSCs are more dependent on Tcf1 and Lef1

  Potential break-through technology poised to overcome these above-mentioned limitations is that of the “substrate mediated enzyme prodrug therapy”, SMEPT (Fig. 1). Learning from the previously established enzyme prodrug therapies (EPT) and specifically the antibody-directed EPT (ADEPT) [12], develop

  Of the acidic hydroxyazoles involved, hydroxypyrazole had the weakest acidic profile (pKa in the range of 6–7), although highly deprotonated at physiological pH. During hit optimization, the two pyrazole ring positions available for substitution provide an opportunity for a better exploration of the

PCR amplifications were performed using genomic DNA from the different organisms studied as template and two degenerate oligonucleotides (PP1 and PP2) as primersPP1 corresponded to the sense codons of the amino Dextran sulfate sodium salt motif AGGI(A/S)EM, and PP2 to the antise

  Given a disruption of membrane internalization and an increase in synaptic glutamate receptors in CPG2 knockdown neurons, one might expect an increase in dendritic spine size as membrane continues to be inserted into the spines during receptor exocytosis. However, we observed the opposite phenotype,

  Introduction Maintaining the normal function of fetal trophoblasts is essential for a successful pregnancy. Preeclampsia (PE), a pregnancy-specific disorder, is often associated with excessive trophoblast cell apoptosis and superficial trophoblast invasion leading to insufficient spiral artery re
