Description
Analysis of differentiated Caco-2 intestinal epithelial cell line cocultured with probiotics L. acidophilus NCFM, B. lactis 420, L. salivarius Ls-33 bacterial cells or treated with cell-free supernatant, and with E. coli O157:H7 cell-free supernatant. Lactobacillus and Bifidobacterium are important genera suggested to be beneficial for human health and E. coli O157:H7 is a pathogen causing hemorrhagic colitis and hemolytic uremic syndrome. Results provide insight into the mechanisms underlying the beneficial effects of probiotics on intestinal epithelial cells and a comparison to pathogenic E. coli.

Description
SUN (Sad1 and UNC-84) and KASH (Klarsicht, ANC-1 and Syne homology) proteins are constituents of the inner and outer nuclear membranes. They interact in the perinuclear space via carboxy-terminal SUN-KASH domains to form the Linker of Nucleoskeleton and Cytoskeleton (LINC) complex thereby bridging the nuclear envelope. LINC complexes sustain numerous biological processes by connecting chromatin with the cytoplasmic force generating machinery. Here we show that the coiled-coil domains of SUN-1 are required for oligomerization and retention of the protein in the nuclear envelope, especially at later stages of female gametogenesis. Consistently, deletion of the coiled coil domain makes SUN-1 sensitive to unilateral force generation across the nuclear membrane. However, absence of this domain does not lead to different expression levels of sun-1 and other known meiotic genes in the mutant compared to wild type. Premature loss of SUN-1 from the nuclear envelope leads to embryonic death due to loss of centrosome-nuclear envelope attachment. However, in contrast to previous notions we can show that the coiled-coil domain is dispensable for functional LINC complex formation, exemplified by successful chromosome sorting and synapsis in meiotic prophase I in their absence. Overall design: A total number five samples were analyzed including two independent wild-type replicates and three independent mutant replicates by PE 50bp RNASeq.

Description
TET proteins oxidize 5-methylcytosine to 5-hydroxymethylcytosine and further oxidation products in DNA. Here we report that simultaneous deletion of Tet2 and Tet3 in mouse double-positive thymocytes resulted in dysregulated development and proliferation of invariant natural killer T (iNKT) cells. Tet2-Tet3-double-deficient (DKO) iNKT cells displayed pronounced skewing towards the NKT17 lineage, with increased DNA methylation and impaired expression of genes encoding the key lineage-specifying factors T-bet and ThPOK. Transfer of purified Tet2-Tet3 DKO iNKT cells into immunocompetent recipient mice resulted in uncontrolled expansion dependent on the nonclassical MHC protein CD1d, which presents lipid antigens to iNKT cells. Our data indicate that TET proteins regulate iNKT cell fate by ensuring proper development and maturation and suppressing aberrant T cell antigen receptor (TCR)-mediated proliferation. Overall design: DKO vs. wild type
Publication Title
TET proteins regulate the lineage specification and TCR-mediated expansion of iNKT cells.

Description
Interrogation and control of cellular fate and function using optogenetics is providing revolutionary insights into biology. Optogenetic control of cells is achieved by coupling genetically encoded photoreceptors to cellular effectors and enables unprecedented spatiotemporal control of signaling processes. Here, a fast and reversibly switchable photoreceptor is used to tune the mechanical properties of polymer materials in a fully reversible, wavelength-specific, and dose- and space-controlled manner. By integrating engineered cyanobacterial phytochrome 1 into a polyethylene glycol matrix, hydrogel materials responsive to light in the cell-compatible red/far-red spectrum are synthesized. These materials are applied to study in human mesenchymal stem cells how different mechano-signaling pathways respond to changing mechanical environments, and to control the migration of primary immune cells in 3D. This optogenetics-inspired matrix allows addressing fundamental questions of how cells react to dynamic mechanical environments. Further, remote control of such matrices could create new opportunities for tissue engineering or provide a basis for optically stimulated drug depots. Overall design: Analysis of global gene expression changes due to differences in the mechanical properties of the phytochrome-based hydrogels

Human CD4 positive T cells were isolated from cord blood using CD4 positive isolation kit from Dynal. Cells were activated with plate bound anti-CD3 and soluble anti-CD28 in presence (iTreg) or absence (Th0) of IL2, TGF beta and ATRA. The cells were harvested at 0, 0.5, 1, 2, 4, 6, 12, 24, 48, and 72 hours. Overall design: Comparing the gene expression in activated CD4+ cells and iTreg differentiated cells in human. 9 time points, 3 replicates for each time point.

Description
Elucidating the top of the mammary epithelial cell hierarchy is highly important for understanding its regeneration capabilities and identifying target cells for transformation. Aiming for enriched mammary epithelial stem cell population, CD200highCD200R1high epithelial cells were identified. These cells represent ~50% of the mammary repopulating units (MRUs, CD49fhigh CD24med ) and termed MRUCD200/CD200R1. Gene expression of these cells was compared to all other MRU cells, termed MRUnot CD200/CD200R1, as well as individual CD200+ population (MRU-CD200R1-) and CD200R1+ population (MRU-CD200-). Overall design: Gene expression from mammary epithelial cells carrying sorted by CD200, CD200R1 markers and MRU markers. Four populations were sequenced: MRU-positive CD200 positive and CD200R1 positive; MRU-positive and not CD200 positive CD200R1 positive; not MRU CD200 positive CD200R1 negative; not MRU CD200 negative CD200R1 positive. There are 5 replicates from 5 individual mice.
