  Here we uncover a highly diverse superfamily of self-replicating MGEs, dubbed pipolins, which are present in three major bacterial phyla, as well as in mitochondria, and encode divergent PolB carrying TPR1 and TPR2 subdomains. Biochemical characterization of a representative enzyme encoded by a pipo

  Authors’ contributions Acknowledgements Introduction Retinoic rolipram is a key signalling molecule in healthy development and in differentiation of stem cells, albeit uncontrolled levels of retinoic acid can lead to mutagenesis [1]. In eukaryotes retinoic acid is made by oxidation of all-t

  2019-09-27

  

  Cytochromes P450 (CYP 450) are a superfamily of hemoproteins containing a heme cofactor, which are widely distributed in animals, plants and microbes (Hannemann et al., 2007). CYP450 exhibits a variety of biological functions including biotransformation of drugs, detoxification of endogenous and xen

  The collagen field undoubtedly regains attractiveness with the emergence of new concepts (cell niche, regulation of growth factor bioavailability, mechanotransduction, cell microenvironment sensing) and new tools to investigate their in vivo functions (atomic force microscopy (AFM), second harmonic

  2019-09-27

  

  It is well known that Doxorubicin-induced cardiotoxicity occurs via p53-mediated apoptosis (Lorusso et al., 2007). However, there are few studies elucidating the mechanism of HFS induced by PLD. We found that PLD induces keratinocyte apoptosis in a very low dose, and the damage induced by PLD cannot

  Materials and methods Results Discussion For many years, oral PDE5-Is have been prescribed as an on-demand regimen for treating ED. Several studies have reported on the efficacy and safety of such a regimen, with an overall efficacy rate of 60–70% [21]. However, many patients complain of a

  2019-09-27

  

  The interaction of EPAC2 with Rim1 has an important role in regulating neurotransmitter release. In addition, a recent EPAC2 knockout mice model study provides evidence that EPAC2 promotes transmitter release by maintaining the readily releasable pool (RRP) at mossy fiber (MF) synapses in the hippoc

  Methods Results Discussion Here we have shown that two GPCR subtypes thought to trigger similar signalling events by coupling to Gαq in fact regulate different signalling networks via coupling to distinct G proteins. Thus global effects regulated by both receptors in events such as cardiac

  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

  One of the isolated interactors against Mulan259–352–Ube2E3 fusion bait was found to be the GABARAP protein, a known member of the Atg8 family that includes LC3 [20]. The Atg8 family-of-proteins are major players in autophagy/mitophagy since they are part of the autophagosome [20], [21], [22]. Our s

  Two key enzymes play important roles in the bioconversion of xylitol from d-arabitol, namely d-arabitol dehydrogenase (ArDH) and NADH-dependent xylitol dehydrogenase (XDH), respectively (Qi et al., 2014). In an earlier study, we developed a high xylitol yield strain by expressing xdh in E. coli BL21

  A cocktail approach can detect the activities of multiple CYP 450 isoforms following administration of multiple CYP-specific substrates in a single experiment. Caffeine, losartan, omeprazole, dextromethorphan and midazolam are often used as substrates in “cocktail probes” of human cytochrome CYP1A2,

  The second part of this study evaluated the role of CK1 in the eFABP4 cellular uptake in endothelial cells. By blocking CK1 expression using a specific siRNA, we corroborated that the presence of CK1 was fundamental for FABP4 cellular uptake and internalization in endothelial cells, thus decreased m

  Acknowledgments Introduction Cell cycle arrest or delay may occur at 3 major checkpoints, i.e. G1/S, intra-S and G2/M. p53 has a central role in controlling the G1/S checkpoint, and its loss or deactivation, occurring in the majority of cancers, forces cancer cells to rely on the S and G2/M ch
