  2020-04-26

  

  Extracellular uridine can be transported across the cell membrane to enter the nucleotide salvage pathway. A colon cancer cell line supplemented with uridine was capable of growing normally in the presence of 1 μM brequinar (Peters et al., 1992). The supplemented uridine may be transported into the

  There are some limitations to our study. First, the small sample size, even if comparable or higher than most studies, did not offer the possibility to consider other variables, such as frequency of use or age of onset. Second, since most subjects did not report current use, we could not analyze sep

  Does hydroxylation of proline have a specific role in the structure and function of the conotoxins? Several studies in the literature provide insights into the role of proline hydroxylation in the Conus peptides. The consequences of proline hydroxylation on oxidative folding and biological activity

  2020-04-22

  

  The kinase activity of DNA-PKcs is essential for NHEJ, but the exact role of the enzymatic activity of DNA-PKcs plays in NHEJ is not fully understood [57]. In vitro, DNA-PKcs can phosphorylate each of the canonical NHEJ factors including Ku70/80 [58], [59], XRCC4 [60], [61], Caspase-10/b, human reco

  Recent data obtained with etifoxine suggest that facilitation of GABAergic inhibition may be also associated with an indirect mechanism implying activation of the peripheral benzodiazepine receptor with a subsequent increase in neurosteroid production (Schlichter et al., 2000, Verleye et al., 2005).

  2020-04-22

  

  Several studies have already shown that mPR activation can significantly reduce intracellular cAMP levels in different kind of cells, such as GT1-7 neuronal cells [32], MDA-MB-468 breast cancer cells [55] and primary vascular endothelial cells [56]. The experiments performed with PTXa and 8-Br-cAMP

  Regarding eicosanoid production, iPLA2-VIA appears, in general terms, not to play a major role in mediating this response in innate immunity and inflammation, as evidenced by the large number of studies highlighting the lack of effect of selective inhibition of the enzyme in stimulus-induced AA rele

  Since ET-1 was discovered first and showed a wide variety of actions not only on the cardiovascular system but also on various other tissues, much information has accumulated on ET-1 compared with the two other peptides. The method for measurement of ET-1 levels in plasma or various tissues by means

  Our data also showed that D2 dopamine receptor was down-regulated in the hippocampus, NAc and striatum of F1-MEP animals, which was only significant in the hippocampus. Both agonists and antagonists of D2 dopamine receptor are able to decrease heroin self-administration (Hemby et al., 1996; Rowlett

  Confirmation of the presence of H+-PPase genes in the genomes of the different protists tested was obtained by Southern blot analyses using the PCR-amplified DNA fragments as probes (Fig. 3). In the trypanosomatids L. major and T. cruzi and the euglenoid A. longa, a single band appeared in the filte

  2020-04-22

  

  CCR7 is another chemokine receptor that is upregulated in CLL [3], [61], [71], [96] and is believed to play a role in enabling cell entry into lymph nodes [97]. Higher mRNA and protein expression of CCR7 has been observed in unmutated compared to mutated IGHV CLL [46] and increased expression has be

  2020-04-22

  

  After activation, AKT phosphorylates target proteins involved in cell growth, metabolism and survival (Manning and Cantley, 2007). For example, AKT phosphorylates the pro-apoptotic protein BAD, preventing it from binding to and inactivating Bcl-xL in mitochondria (Datta et al., 1997). In turn, Bcl-x

  In our recent study, we established a procedure to examine the chromatin binding of XRCC4 using a biochemical fractionation analysis using a detergent Nonidet P-40 [22]. In this study, we investigated the role of LIG4 and its subdomains in the recruitment of XRCC4/LIG4 complex to chromatin. Mater

  To assess which export pathway is used by the iNOS mRNA, we inhibited CRM1 activity by incubation of DLD-1 MLN120B with LMB. Since LMB covalently and exclusively binds to CRM1, it represents a potent and specific inhibitor of the CRM1 transport activity [38]. Inhibition of CRM1 activity as well as

  In addition to PGC1α, transcriptional co-repressors such as NCOR and RIP140 participate in oxidative muscle remodeling induced by exercise, whereby reductions in their expression and the resulting de-repression of downstream TFs activates oxidative gene expression (Seth et al., 2007, Yamamoto et al.
