Thus, we report further evidence that FAT10 is involved in antigen processing which may provide a functional rationale why FAT10 is selectively induced upon DC maturation.The canonical Wnt/β-catenin signaling pathway regulates cell proliferation in development and adult tissue homeostasis. Dysregulated signaling contributes to human diseases, in particular cancer. Growing evidence suggests a role for clathrin and/or endocytosis in the regulation of this pathway, but conflicting results exist and demand a deeper mechanistic understanding. We investigated the consequences of clathrin depletion on Wnt/β-catenin signaling in cell lines and found a pronounced reduction in β-catenin protein levels, which affects the amount of nuclear β-catenin and β-catenin target gene expression. Although we found no evidence that clathrin affects β-catenin levels via endocytosis or multivesicular endosome formation, an inhibition of protein transport through the biosynthetic pathway led to reduced levels of a Wnt co-receptor, low-density lipoprotein receptor-related protein 6 (LRP6), and cell adhesion molecules of the cadherin family, thereby affecting steady-state levels of β-catenin. We conclude that clathrin impacts on Wnt/β-catenin signaling by controlling exocytosis of transmembrane proteins, including cadherins and Wnt co-receptors that together control the membrane-bound and soluble pools of β-catenin.Inflammatory bowel diseases (IBDs) are caused by inflammation of the gastrointestinal tract, which may or may not have a specific cause or pathogen. They affect millions of people around the world and there are still few effective treatments. The aim of this work is to investigate anti-inflammatory effect of IKK-β inhibitor, LASSBio-1524, and its three analogues, LASSBio-1760, LASSBio-1763 and LASSBio-1764 in experimental animal models of intestinal inflammatory diseases, in mediators production and expression of inflammatory enzymes. Colitis was performed using two different models, which mimic Crohn's disease (induced by dinitrobenzene acid, DNBS) and ulcerative colitis (induced by sodium dextran sulphate, DSS) in mice. In both models was performed a therapeutic protocol with 1, 3 or 30 μmol/kg daily dose. LASSBio-1524 and its three analogues reduced the secretion of TNF-α, IL-1β, IL-6, IL-12, IFN-γ and increased secretion of IL-10, protecting gastrointestinal homeostasis. All compounds reduced macro and microscopic colonic damage caused by experimental colitis and p38 MAPK expression in the colon, as well as leukocytosis and anemia resulting from the disease. Our data may suggest LASSBio-1524 and its analogues (LASSBio-1760, LASSBio-1763 and LASSBio-1764) as promising candidates for new prototypes designed to inflammatory bowel diseases treatment.ME-344 is a second generation cytotoxic isoflavone with anticancer activity promulgated through interference with mitochondrial functions. Using a click chemistry version of the drug together with affinity enriched mass spectrometry, voltage-dependent anion channels 1 and 2 (VDAC1, 2) were identified as drug targets. To determine the importance of VDAC1 or 2 to cytotoxicity we used lung cancer cells either sensitive (H460) or intrinsically resistant (H596) to the drug. In H460 cells, depletion of VDAC1 and VDAC2 by siRNA impacted ME-344 effects by diminishing generation of reactive oxygen species (ROS); preventing mitochondrial membrane potential (ΔΨm) dissipation; moderating ME-344-induced cytotoxicity and mitochondrial mediated apoptosis. Mechanistically, VDAC1 and VDAC2 knockdown prevented ME-344-induced apoptosis by inhibiting Bax mitochondrial translocation and cytochrome c release as well as apoptosis in these H460 cells. We conclude that VDAC1 and 2, as mediators of the response to oxidative stress, have roles in modulating ROS generation, Bax translocation and cytochrome c release during mitochondrial-mediated apoptosis caused by ME-344.Comparative transcriptomics between differentiating human pluripotent stem cells (hPSCs) and developing mouse neurons offers a powerful approach to compare genetic and epigenetic pathways in human and mouse neurons. To analyze human Purkinje cell (PC) differentiation, we optimized a protocol to generate human pluripotent stem cell-derived Purkinje cells (hPSC-PCs) that formed synapses when cultured with mouse cerebellar glia and granule cells and fired large calcium currents, measured with the genetically encoded calcium indicator jRGECO1a. To directly compare global gene expression of hPSC-PCs with developing mouse PCs, we used translating ribosomal affinity purification (TRAP). As a first step, we used Tg(Pcp2-L10a-Egfp) TRAP mice to profile actively transcribed genes in developing postnatal mouse PCs and used metagene projection to identify the most salient patterns of PC gene expression over time. We then created a transgenic Pcp2-L10a-Egfp TRAP hPSC line to profile gene expression in differentiating hPSC-PCs, finding that the key gene expression pathways of differentiated hPSC-PCs most closely matched those of late juvenile mouse PCs (P21). Comparative bioinformatics identified classical PC gene signatures as well as novel mitochondrial and autophagy gene pathways during the differentiation of both mouse and human PCs. click here In addition, we identified genes expressed in hPSC-PCs but not mouse PCs and confirmed protein expression of a novel human PC gene, CD40LG, expressed in both hPSC-PCs and native human cerebellar tissue. This study therefore provides a direct comparison of hPSC-PC and mouse PC gene expression and a robust method for generating differentiated hPSC-PCs with human-specific gene expression for modeling developmental and degenerative cerebellar disorders.The defining characteristic of hole-doped cuprates is d-wave high temperature superconductivity. However, intense theoretical interest is now focused on whether a pair density wave state (PDW) could coexist with cuprate superconductivity [D. F. Agterberg et al., Annu. Rev. Condens. Matter Phys. 11, 231 (2020)]. Here, we use a strong-coupling mean-field theory of cuprates, to model the atomic-scale electronic structure of an eight-unit-cell periodic, d-symmetry form factor, pair density wave (PDW) state coexisting with d-wave superconductivity (DSC). From this PDW + DSC model, the atomically resolved density of Bogoliubov quasiparticle states [Formula see text] is predicted at the terminal BiO surface of Bi2Sr2CaCu2O8 and compared with high-precision electronic visualization experiments using spectroscopic imaging scanning tunneling microscopy (STM). The PDW + DSC model predictions include the intraunit-cell structure and periodic modulations of [Formula see text], the modulations of the coherence peak energy [Formula see text] and the characteristics of Bogoliubov quasiparticle interference in scattering-wavevector space [Formula see text] Consistency between all these predictions and the corresponding experiments indicates that lightly hole-doped Bi2Sr2CaCu2O8 does contain a PDW + DSC state.
