  The authors identified inhibitors of SUMOylation using two assays to monitor the conjugation of SUMO1 to RanGAP1 by E1 and E2 enzymes: a fluorescence resonance energy transfer (FRET) primary screen that evaluated over 250,000 compounds and a chemiluminescence secondary screen. A counter screen was u

  2020-05-14

  

  As DNA methylation plays a critical role in organismic development and human diseases, the interest in DNA methyltransferases is constantly increasing. Extensive studies on the repertoires of dnmts genes have indicated increasing dnmts members in eukaryotes (Goll and Bestor, 2005; Ponger and Li, 200

  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

  The ubiquitin–proteasome system (Ub–P) is the main cellular machinery for protein turnover in eukaryotic cells (Glickman and Ciechanover, 2002). Degradation by Ub–P involves two steps. Target proteins are selectively, specifically, and covalently attached to ubiquitin (Ub) chains, followed by Ub-tag

  In summary, these results are consistent with our hypothesis that chemical nitrosation of BMAA to N-BMAA results in the formation of an alkylating agent. Furthermore, we have shown that N-BMAA is more toxic than BMAA itself. Previously, methylazoxymethanol (MAM), which is also present in the cycad

  ASC was reported as a potent antiviral and antifungal agent, and its derivatives could modulate a variety of physiological activities, such as anti-tumor, anti-metastatic, and anti-diabetic activities in animals. Mie Tsuruga et al. found that 4-o-methylascochlorin had immunosuppressive activity, but

  2020-05-13

  

  Although DAPK has been implicated in neuronal death in ischemic stroke and neurodegenerative diseases, such as Alzheimer’s disease (Shamloo et al., 2005, Duan et al., 2013), the mechanisms about how DAPK regulates cell death are still elusive. In the present study, we investigated the signal transdu

  Considering the divergence of multiple DGAT isoforms, we examined whether MiDGAT1 and MiDGAT2s utilized different fatty acids as the substrate to synthesize TAGs. GC-MS analysis indicated that C16:0 and C18:0 were the major components of TAGs in yeast cells, and all three MiDGATs displayed the same

  Another significant finding in our study was the demonstration that the axon-protective action associated with CK2 inhibition correlated with preservation of mitochondrial structure and function in NCT-503 synthesis (Fig. 11). Because of the consistent protection conferred by CK2 inhibition during

  Two additional hydrogen-bonds are formed by the -substituted methoxy-group with Ser and Asp. Ser exerts the role of a gate keeper in CK1: Entry of the ATP in the binding-site causes a conformational change into the closed form by Ser, which locks the binding-site and prevents ATP-diffusion out of th

  The ACC receptor family appear to be attractive targets for the development of novel anthelmintics. With this in mind we also tested the activity of the anthelmintics levamisole and pyrantel which activate the nematode nAChR (Martin and Robertson, 2007). We found both molecules were partial agonists

  2020-05-12

  

  Ultrasound is an acoustic wave with a frequency >20 kHz that needs a medium to propagate [20]. Accompanied by the spread of an ultrasonic wave, a series of alternating cycles of compression and rarefaction emerge in the liquid medium. During the rarefaction cycle, microbubbles are formed because of
