  Perturbations in lumiracoxib are known to induce apoptosis. Our results show that a fraction of the DT40YB-1b+/− cells, in addition to becoming tetraploids, undergo apoptotic cell death. Similar observations linking polyploidy and apoptosis have been made in the past [23], [30], [31], [32], [33], [

  2020-12-09

  

  During mouse embryogenesis, RLIM protein is detectable throughout preimplantation development, consistent with its functions in iXCI maintenance. However, in contrast to differentiating ESCs in culture (Figure 2A), RLIM protein levels are downregulated in nuclei of epiblast cells of implanting embry

  Activatable optical imaging probes Optical fluorescence imaging, which directly detects photons emitted from fluorescent probes, has become as a powerful analytical method to study biological processes both in vitro and in vivo. It is characterized by high sensitivity, is free of radioactive irra

  2020-12-09

  

  A major open question in the field of lipid mediators is the molecular nature of the PLA2 enzyme involved in the release of DHA and related omega-3 fatty acids from phospholipids as a first committed step for the generation of SPMs. Although by analogy with AA it is often assumed that cPLA2α may ser

  On the opposite side, sPLA2-X has also been implicated in the pathology of cancer [167,168]. Human sPLA2-X induces lipid droplet formation in Ras-driven MDA-MB-231 triple-negative breast cancer nigericin and promotes their survival during nutrient stress. It acts through the products of its enzymat

  Since the 1,2-dideoxy analogues, and , served as substrates for TgTCEA and TgTCEB, respectively, with the higher affinity (lower ) and lower turnover number (lower ) than their authentic substrates, PosA and PosB (such trend was more evident on analogue for TgTCEB than on analog for TgTCEA), an intr

  2020-12-09

  

  Our previous work has demonstrated that two glutamate residues (Glu-305 and Glu-331 in murine and human TPP II) in the active site are important for exopeptidase activity in mTPP II [17]. At least one of these, Glu-331, seems to form a salt bridge to the N-terminal amino group of the substrate, posi

  While oxysterols were most extensively studied for its potent ability to mediate feedback regulation of cholesterol biosynthesis, some early investigations showed that the enzymes involved in its syntheses were highly upregulated in macrophages and dendritic cells—an indication of possible roles in

  Currently, much effort has been made to design and synthesize ThDP analogs (such as ThTDP, ThTTDP, and triazole-ThDP in Fig. 2)8, 9, 10, 11, 12 as PDHc E1 inhibitors. These ThDP analog inhibitors, such as ThTDP and ThTTDP, can block the ThDP binding site, and exhibit significantly stronger binding a

  2020-12-08

  

  To study the role of DNA–PK in the response to replication arrest, we used the DNA replication inhibitor aphidicolin (APH). APH, a mycotoxin isolated from Cephalosporium aphidicola, inhibits DNA replication by interacting with the replicating DNA polymerase α (pol α). APH specifically inhibits the a

  A recent study revealed that in human glioma cells, DNA-PKcs interacted with the regulatory γ subunit of AMPK and positively regulated AMPK phosphorylation and activation under glucose-deprived conditions. This suggested that DNA-PK is an important regulator of AMPK activation in response to energy

  Members of the Nudix family typically contain a 23-amino-acid sequence (Nudix box) of GxExREUxEExGU, where U is usually Ile, Leu, or Val and x represents any amino acid. The EUxEE core residues serve as anchors for an Mg ligand that associates with a characteristic pyrophosphate linkage that is comm

  Consistent with previous simulations on the DFG-Asp-out/-in interconversion of Abl kinase, we only observe the DFG flip with protonated Asp747 (Shan et al., 2009). We showed previously that the pKa for the DFG-Asp in Abl is elevated at 6.5. Further “constant pH” simulations whereby protonation event
