  Our study provides proof of principle for dimerizing two different E3 ligases as a novel approach to inducing one ligase to degrade the other one. The outcome of ‘ligase versus ligase’ PROTAC-mediated activity might be unpredictable a priori, but could reveal a new mechanism for proximity-mediated h

  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

  2019-10-03

  

  In the gel shown in Figure 8, at early time-points, 14% of the input dsDNA is converted to these intermediate species. These persist in the gel to later times, with approximately 50% of these being unwound. This unwinding occurs at a considerably slower rate and is due to that fraction of the popula

  An increasing body of evidence demonstrates that MXC can cause neurobehavioral and neuropathological alterations [7]. In the brain, there are several steroidogenic enzymes, which are responsible for neurosteroid production. Neurosteroids are subsets of steroids that rapidly change neuronal excitabil

  In this report we describe studies of the effects of peroxisome proliferator-activated receptor γ (PPARγ) and acyl-CoA synthetase (ACSL1) on palmitate-induced ER stress in the human cardiomyocyte-like cell line AC16 [22], which was derived from adult ventricular heart tissue. PPARγ is a nuclear rece

  2019-10-02

  

  Introduction O6-Methylguanine-DNA methyltransferase (MGMT) is a DNA-repair enzyme that specifically transfers alkyl adducts from the O6 position of guanine to the cysteine residue (Cys145) in its active site. In cancer cells, this ability of MGMT disrupts the cytotoxic actions of alkylating antic

  2019-10-02

  

  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

  2019-10-02

  

  CDK6 lacks DNA-binding domains and nuclear localization sequences, and therefore will probably be transported to the nucleus by a ‘piggy-back’ mechanism and needs to contact its specific sites indirectly through DNA-binding proteins. Besides NF-κB p65, a further candidate transcription factor is PAX

  Under optimized assay conditions, very low concentrations (20pM) of [125I]YP20 bound to hCRF1-CHO PSI-6206 and membranes with high specificity (>95% inhibited by 1μM astressin) and in a membrane protein-dependent manner. Specific binding was selective vs. the hCRF2α subtype because little specific

  In this study, we further investigated the involvement of CRF1 and CRF2 receptors of the dPAG in the regulation of panic-related responses. For this, we used two animal models that associate escape behavior with panic attacks: the elevated T maze and the electrical stimulation of the dPAG (for a ful

  Other mutations in the SYNE1 3′ region (exons 81–85) have been implicated in an upper motor neuron disease, ARCA1 (Gros-Louis et al., 2007). The disease is characterized by progressive movement, coordination, and balance problems caused by disrupted Purkinje cell function and their impaired signalin

  Leukotrienes themselves are implicated in the development of gastrointestinal ulcers, asthmas, and different inflammatory processes [18], [19]. It is noteworthy that COX isozymes and LOX share the same substrate arachidonic acid; therefore, inhibition of prostaglandins production by cyclooxygenase p

  The evaluation of internal exposure in workers with omethoate is challenging. Unfortunately, OPs are metabolized and excreted quickly in the urine usually within 24–48 h of exposure, and the variation in metabolic rates exists. Many factors influence daily urinary output, such as salt intake, urea a

  Considering these reports, and with the aim of further investigating the mechanism by which the cAMP-Epac/PKA pathway activates eNOS, we have performed imaging experiments evaluating the effect of drugs that increase cAMP or modify its signalling pathways (PKA or Epac activators and inhibitors) on b
