  2021-05-06

  

  25-OHC is a potent regulator of LXR-mediated pathways, that impact on Tirapazamine lipid homeostasis [8]. This oxysterol affects expression of the cholesterol efflux pumps ATP-binding cassette transporter (ABC)A1 [9] and ABCG1, and expression of apolipoprotein E [10], [11], [12]. 25-OHC is able to

  Introduction Structure of the Ku heterodimer associated to DNA The atomic structure of the Ku heterodimer, alone and bound to a small DNA fragment, was recently determined (Walker et al., 2001) and has significantly improved our understanding of DNA recognition by DNA-PK holoenzyme (Fig. 3). B

  Importantly, in genetic studies, Saccharomyces cerevisiae Pif1, a member of the SF1 family of helicases, has been implicated in BIR in conjunction with Pol δ (Chung et al., 2010, Saini et al., 2013, Wilson et al., 2013). Using highly purified S. cerevisiae proteins, a system that permits dissection

  Nowadays, colorimetric assay has been applied in detecting DNA MTase activity. Li et al. used DNA modified gold nanoparticles (AuNPs) coupled with enzyme-linkage reactions to detect the activity of methylases [20]. In a previous study, our group presented a label-free colorimetric method, using unmo

  Nuclear estrogen receptors: Indirect genomic signaling As mentioned earlier, the transcription of several genes that do not contain EREs in their promoter regions can also be regulated by estradiol, without direct binding of the estrogen receptors to the DNA. According to the most recent reports,

  SIRT1 is a representative member of Sirtuins, which is a family of highly conserved NAD+-dependent class III histone deacetylases. SIRT1 deacetylates plentiful nonhistone protein substrates [Atgs, Foxo1, Foxo3, PGC-1α, NF-kB, E2F1 and p53] (Conrad et al., 2016; Gu et al., 2016; Tu et al., 2018) to p

  2021-04-30

  

  Although both DNA DSBs and DNA-PK activity increase with aging in skeletal muscle (Figure 1), we cannot conclude that aging-associated increase in DNA-PK activity is solely mediated by chromosomal breaks, as DNA-PK is also activated independently of chromosomal breaks by ROS (Li et al., 2014), which

  A set of small molecule LigI inhibitors were identified through an in silico structure-based screen, using the atomic resolution structure of LigI complexed with nicked DNA [[18], [26]]. This screen yielded inhibitors that were selective for LigI (L82), inhibited both LigI and LigIII (L67) and inhib

  Multiple protein species are known to naturally exist for the transmembrane receptors DDR1 and DDR2. Five splice variants have been characterized for DDR1 (“a” through “e”). The d and e isoforms lack the intracellular kinase domain of DDR1. The splicing of DDR1 to various extents has been reported i

  As described above, when EGCG was orally administered, CYP3A expression in the liver decreased; however, the CYP3A expression level in the intestine was unchanged (Fig. 3). Although we remain speculative, one reason for this may be that because the level of intestinal bacteria in the upper part of
