  2021-03-02

  

  A recent report has shown that C. elegans homozygous for a point mutation within the HORMA domain of HTP-1 (M127K), which disrupts its association with chromosome axes, displayed an extended zone of PLK-2 localization to PCs in response to asynapsis (Silva et al., 2014), which, as we show here, is a

• I bungarotoxin competes with ACh

  2021-03-02

  

  [125I] α-bungarotoxin competes with ACh, an endogenous activator of α7-nACh receptors by binding to the ACh binding site on the receptor (Albuquerque et al., 2009). For this reason, the effect of curcumin was investigated on the specific binding of [125I] α-bungarotoxin. Saturation curves for the bi

• The EGFR belongs to the ErbB family

  2021-03-01

  

  The EGFR belongs to the ErbB family of receptor tyrosine kinases (RTKs), comprised of four members: EGFR (ErbB1, HER1), HER2 (ErbB2), HER3 (ErbB3) and HER4 (ErbB4) [24]. HER receptors are activated by a group of epidermal growth factor (EGF) ligands and undergo homo- or hetero-dimerization during th

  2021-03-01

  

  At the therapeutic level, the logical approach to address the cooperation between FGFR4 and EGFR was the combined inhibition of both receptors. To explore the potential efficacy and specificity of this approach, we tested the effect of FGFR and EGFR inhibitors in monotherapy or in combination in syn

  A brief history of RBR E3s RBR E3s were originally defined based on sequence alignments that predicted a tripartite motif of three zinc (Zn)-binding domains: two RING domains (RING1 and RING2) connected via an in-between-RING (IBR) domain [28], [29]. The prediction together with initial observati

  2021-03-01

  

  E1 is a classical initiator protein and, as such, plays several roles in the initiation and catalysis of viral DNA synthesis. E1 must first recognize a specific segment of the viral martphone known as the “origin of DNA replication”, or “ori” for short. For most PV types examined to date, the minim

  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

  Verapamil, a calcium channel blocker used clinically as a coronary vasodilator, was amongst the first compounds identified that could reverse MDR and potentiate the effects of MDR1 substrates such as vincristine [15], [16]. Verapamil, along with a number of other MDR1 blockers, have proved largely u

  Real-time PCR, as described previously with minor modifications, was used to detect DNA . The PCR mixture (Qiagen) was as follows: 5mM MgCl2, 2.5μl of 10x PCR Buffer, 0.125μl of HotStarTaq DNA Polymerase, 0.25mM of each dNTP, 0.4μM of each primer and 0.1μM of FAMlabelled probe (‘5-aacaattggagggcaagg

  As temperatures increase, rates of spontaneous deamination also increase such that hyperthermophilic organisms must have efficient mechanisms for dealing with this potential hazard.8., 9. The hyperthermophile Methanococcus jannaschii has both a dCTP deaminase (encoded by the gene at locus MJ0430) an

  2021-03-01

  

  Unlike CRM1, exportins Cse1 and Xpot lack a C-extension and instead rely primarily on changes in HEAT-repeat conformation and direct Ran-cargo contacts to ensure low cargo-binding affinity in the cytosol and cooperative assembly of the exportin/Ran/cargo complex in the nucleus (Cook et al., 2005, Co

  Third, we also found negative correlations between TREM2 mRNA expression and the methylation rate of 4 CpG sites in the intron 1 of TREM2. Gene methylation rates are generally associated with gene expression. Thus, heavily methylated areas of genes are usually less active at the transcriptional leve
