  2020-03-07

  

  A role for the E2–E3 interface in governing mono- versus polyubiquitination is not mutually exclusive with that of the E2 backside, which has previously been shown to mediate polyubiquitination through its ability to bind to Ub [21], [25], [33]. Brzovic and colleagues first demonstrated the importan

  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

  2020-03-07

  

  In glioblastoma, methylation of pMGMT is predictive of the efficacy of temozolomide with an increased survival [22], [23], [24], [25]. As in glioblastoma [24], [26], [27], [28], pMGMT methylation assessed by pyrosequencing (with immunochemistry, IHC) is the most effective and reproducible technique

  2020-03-07

  

  Instead of receptor interaction or GT activity, we focused on the CPD and autoprocessing. The CPDs from the 2 toxins are highly homologous: each cysteine protease targets an intramolecular substrate and mediates InsP6-induced autoprocessing to release the GTD into host cytosol.40, 41 However, TcdB i

  The androgen receptor (AR) is a steroid hormone receptor that plays a crucial role in the normal development of male reproductive tissues, and its high expression and/or relaxation of its regulation are strongly implicated in prostate cancer (PCa) [11]. Androgen binding induces conformational change

  Conclusion This patient was hypercoaguable as evidenced by a lower extremity DVT, pulmonary emboli, and a splenic infarct. Excluding acute CMV infectious mononucleosis, she had no disorders predisposing to splenic infarcts.4, 5 In this case, CMV infectious mononucleosis was accompanied by CMV lun

  Halogenases Enzymatic C–H activation leading to halogenation is another emerging area in biocatalysis [55,56]. Incorporation of halogen atoms during medicinal chemistry eff ;orts is a well-established practice, presenting an effective means to control the molecule’s bioactivity and physicochemical

  At baseline, mutant allele frequency of EGFR in tissue and plasma samples did not correlated with anti-tumor response (Supplementary Fig. 1). Among 35 patients who were positive for cell-free DNA (cfDNA) at baseline, changes of cfDNA during treatment were analyzed. Negative conversion (NC) of cfDNA

  Introduction Acinetobacter baumannii is a gram-negative opportunistic pathogen that causes nosocomial infections including pneumonia and bloodstream infections which is associated with an increased mortality and multi-drug resistance [[1], [2], [3]]. A. baumannii was rated as one of the critical

  Author Contributions Acknowledgments Introduction Many anticancer agents bind covalently to DNA, introduce bulky adducts, and inhibit DNA metabolic processes including repair, replication and transcription.1., 2., 3. Frequently, the first enzymes to encounter DNA adducts are DNA helicases.

  We show that direct contact with MSCs is necessary and sufficient to induce DDR2 upregulation in breast cancer cells. DDR2 expression in MSC is required for collagen deposition and leads to increased DDR2 expression and activation in breast cancer cells. This paracrine-autocrine MSC-cancer cell axis

  Introduction Benzanthrone (BNZ) is a dye intermediate used in the synthesis of number of polycyclic vat and disperse dyes. It has been detected as an environmental pollutant in urban ambient air particulates, originating from furnace effluents, municipal refuge, wood and coal combustion and autom

  2020-03-06

  

  The quantification and monitoring of ChEs enzymatic activities have traditionally been associated to environmental studies in order to diagnose the exposure of non-target organisms to specific anti-cholinesterasic agents (Nunes, 2011). The importance of these enzymes as biomarkers of environmental c

  Results Discussion The advent of TKI treatment has greatly improved CML therapy. Because CML LSCs are less sensitive to TKIs, CML is usually controlled rather than cured, highlighting an unmet clinical need. Developed from our previous finding that CML LSCs are more dependent on Tcf1 and Lef1
