  Cells expressing the CDK5 S47D mutant exhibit impaired migration and enhanced proliferation: Finally, we wished to determine the functional significance of this phosphoevent. Multiple studies have implicated active CDK5 in promotion of cell migration [9,16,[21], [22], [23], [24]] and in one study th

  The repeat sequence “TTAGGG” of telomere could be directly recognized by TERF1. TERF1 is indispensable for the maintenance of telomere nmda receptor antagonist structure and integrity (Tan et al., 2017). Trf1 genetic depletion in vivo induces a persistent DNA damage response and telomere uncapping,

  Analysis of DNA fragmentation. We followed a modified Hirt extraction procedure for analysis of DNA fragmentation. Cells were suspended in TNE buffer (1M NaCl, 20mM Tris–HCl, pH 7.4, 2mM EDTA, and 0.6% SDS) at a density of 106 cells/ml and incubated overnight on ice. The next day, cellular debris wa

  Rat pheochromocytoma PC12 cells have been widely used as a cell system to study intracellular signaling leading to neurite outgrowth. The advantages of using PC12 cells in the CHK studies are the fact that they naturally express the rat form of CHK and the observation that down-regulation of CHK fun

  We have previously reported the characterization of A-127722, a novel, non-peptide endothelin antagonist that displays very high affinity binding (K=69 pM) with a more than 1000-fold greater affinity for human endothelin ETA than ETB receptor. Although A-127722 is >1000-fold more selective for endot

  The imaging and biochemical data presented here demonstrated that in T cells, AEP played a specific function in cleaving Foxp3 but not Tbet. These results are in accordance with previous AEP studies where it has been shown that AEP substrates in part are not amenable to other protease activity. In a

  Oxysterols modulate the immune responses and as such could be effectors of the tumor environment: 25-OHC impairs IgA production in B-lymphocytes [26] and induces the secretion of the proinflammatory and angiogenic cytokine IL-8 [27], [28]. Of note, oxysterols (in particular 7α,25-OHC) are potent che

  Main Text Post-translational modifications by ubiquitin (Ub) and ubiquitin-like proteins (Ubl) regulate a diverse array of cellular and physiological processes including protein degradation, localization, and activation. While ubiquitination has primary responsibility for targeting substrates for p

  2020-12-01

  

  Introduction The ubiquitination status of a target protein is achieved via a delicate balance between two opposing forces: ubiquitin E3 ligases and DUBs. It has been postulated that the majority of proteins in a cell are regulated and modified by ubiquitin at some point (Hershko and Ciechanover,

  2020-12-01

  

  Protein deubiquitination is becoming increasingly instrumental in understanding the complexities of the Ub system. Adding to this complexity is the discovery of bacterial effectors with DUB activity that have structurally adapted themselves to interfere with the eukaryotic Ub system (Pruneda et al.

  Localization of D2 receptors in striatum One characteristic of D2Rs that has complicated their study is their expression in multiple neuronal populations within striatum, both pre- and postsynaptically (Beaulieu and Gainetdinov, 2011). In addition to spiny projection neurons (SPNs), which are the

  In light of the overall loss of activity and selectivity observed with this series of arylchromenone-4-ones bearing small -alkoxy substituents, we were pleased to identify a potent and relatively selective inhibitor , exhibiting IC values of 0.008μM and 0.07μM for DNA-PK and PI3Kα, respectively.

  Db model cells showed various aberrant phenotypes that seemed to reflect the pathological abnormalities found under diabetic conditions. First, in Db model cells after insulin stimulation, we found the inhibition of the transcriptional repression of the gluconeogenic genes, PCK1 and G6PC, and aberra
