  The in vitro enantioselective metabolism of pesticides has been investigated by employing human liver microsomes, which are a reliable resource to perform MCL enantioselective risk assessment in humans (Carrão et al., 2019; de Albuquerque et al., 2018, 2016; Yao et al., 2016). The enantioselective m

  In this study we have explored a functional role of the oxysterol/EBI2 system in this process. In 2011 we and others reported the discovery of oxysterols as ligands for EBI2 [6], [7]. Oxysterols are metabolites generated by hydroxylation of cholesterol and have been linked to a variety of fundamenta

  2020-12-30

  

  We elucidated that the ten DGK isozymes have different relative 1-MGK and 2-MGK activities vs DGK activity under the same conditions. However, because the octylglucoside-mixed micellar assay was developed for DGK, it is not known whether the DGKs exhibit maximum 1-MGK and 2-MGK activities in this as

  2020-12-30

  

  In recent years, the use of liquid chromatography/tandem mass spectrometry (LC–MS/MS) has become a preferred approach to measure drugs and metabolites in biological fluids due to its very high selectivity and sensitivity [17], [18], [19], [20], [21], [22], [23], [25], [30]. The great sensitivity of

  Materials and methods Results Discussion In the present study, as a trial to evaluate the marine ciliate E. crassus for further studies, its susceptibilities to B[a]P and β-NF were measured. Acute toxicity of B[a]P in aquatic organisms has been extensively studied, but not enough data is av

  2020-12-30

  

  Hymenialdisine, the most potent inhibitor of parasite TgCK1 enzymes in vitro has no whole cell anti-parasitic activity (Table 2). Like purvalanol B however, this 520 3 synthesis also displays poor activity against target enzymes in cultured cells. For example, in vitro IC50 values for inhibition of

  2020-12-30

  

  Enzyme mimics belong to a type of rising catalysts which show the similar function with their corresponding natural enzymes [20], [21], [22], [23], [24], [25], [26], [27], although their structures are different from natural enzymes. In the area of prodrug activation, the widely-used enzyme mimics a

  Abbreviations Introduction Collagen-induced DDR activation A key feature of DDRs is their ability to bind both fibrillar and non-fibrillar collagens (Shrivastava et al., 1997, Vogel et al., 1997). DDR1 and DDR2 recognize the GVMGVO (O, hydroxyproline) motif within fibrillar collagens I–III

  Two-photon microscopy experiments demonstrated that most contacts between GC B and Tfh cells are of short duration (about 2 min), and only about 4% of these contacts lead to the formation of stable conjugates (5 to 60 min) (Allen et al., 2007). Similarly, during extrinsic peptide stimulation, some r

  Materials and methods Results Artemis has been reported to possess 5′–3′ exonuclease activity in vitro on ssDNA, as well as DNA-PK-dependent endonuclease activity on single-strand overhang and hairpin DNA structures [11]. However, enzymes within the metallo-β-lactamase family typically contain

  Materials and methods Results Discussion DNA-PKcs and the Ku heterodimer (Ku70 and Ku80) constitute the DNA-PK complex, which is a serine/threonine kinase. DNA-PK phosphorylates H2AX and other substrates, such as main NHEJ factors (Artemis, XRCC4, and DNA ligase IV) [4]. Therefore, DNA-PK d

  Our finding that the ATRX-DAXX-H3.3 complex promotes a form of HR is likely to have important implications for our understanding of the ALT recombination process that takes place at telomeres. We were surprised to observe that ATRX promotes a form of HR, since loss of the ATRX-DAXX-H3.3 complex is n

  Here we investigate in more detail how Dot1 function contributes to the regulation of DNA damage tolerance. We find that Dot1 modulates the response to the alkylating agent MMS through its catalytic activity on H3K79. In fact, progressively reduced levels of H3K79 tri-methylation result in gradually

  Keratin 8 (K8) has been identified as the first intermediate filament expressed during development in amphibians and mammals. In zebrafish, a type II cytokeratin 8 (zf-K8) cDNA has been cloned. zf-K8 gene was maternally inherited and expressed in all surface cells throughout the embryonic stages old
