  2020-09-05

  

  Our finding that one enzyme acts both as a primase and a DNAP poses evolutionary and mechanistic questions. In particular, why do cellular organisms require two enzymes to fulfill de novo DNA synthesis? The inability of cellular replicases to perform as primases might be dictated by the challenges a

  We next focused our design building into the ribose binding site, which had not been yet utilized in this effort. Compounds bearing a series of five-membered aromatic heterocycles (compound , ) showed reduced inhibition of the Gram-positive isozymes compared with compound , but a 20-fold improved po

  Materials and methods Results Discussion Although autophagy is known to be implicated in the therapeutic effect of DNA alkylating agents such as MNNG [28], [29], [30], the molecular mechanisms underlying autophagy induced by MNNG remain largely elusive. In this study, we present evidence sh

  Altogether these data suggested that GlmU might be involved in the M. smegmatis biofilm mediated defence mechanisms. GlmU belongs to a metabolic pathway leading to UDP-GlcNAc from fructose-1-phosphate involved in the biosynthesis of peptidoglycan and lipopolysaccharide (Fig. 8). Recently, we demonst

  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

  In this study, we further investigated the involvement of CRF1 and CRF2 receptors of the dPAG in the regulation of panic-related responses. For this, we used two animal models that associate escape behavior with panic attacks: the elevated T maze and the electrical stimulation of the dPAG (for a ful

  2020-09-04

  

  Upstream Stimulatory Factor (USF) binding to the −65 E-box is required for the regulation of FAS promoter activity in fasting/feeding [97], [98]. DNA-PK are identified as a USF-interacting protein [99]. In response to feeding/insulin, the transient double-stranded DNA breaks occurred during the tran

  2020-09-04

  

  Methylation of histone tails is important in regulating mmae structure and transcription. Methylation occurs at arginine and at mono-, di- or tri-methylated lysine residues. The reversibility of histone methylation was recently revealed by the identification of two histone demethylases, LSD1 and JH

  During the past decade, it became increasingly clear that the affinity and efficacy of small agonists acting on the orthosteric binding site of a GPCR can be modulated by ligands that bind to a topographically distinct (allosteric) binding site on the same GPCR molecule 33, 39, 40, 41, 42.

  The phenotypes of KD-Ddr2 transgenic mice were less severe than expected from the results of miDdr2-transfected ATDC5 cells, which indicated that DDR2 might play important roles in endochondral ossification but neither critical nor essential roles in determining total body and skeleton size.

If core cognitive deficits are shown consistently in certain subgroups of gamblers based on genotype,
