Description
MED1 (Mediator complex subunit 1) is expressed by human epidermal keratinocytes and functions as a coactivator of several transcription factors. To elucidate the role of MED1 in keratinocytes, we established keratinocyte-specific MED1-null (MED1epi-/-) mice using the K5Cre-LoxP system.

Description
To elucidate the effect of the polyphenols contained in alcoholic beverages on the metabolic stress induced by ethanol consumption, four groups of mice were fed for five weeks on Lieber's diet with or without ethanol, with ethanol plus ellagic acid, and with ethanol plus trans-resveratrol. Alcoholic fatty liver was observed in the group fed the ethanol diet but not in those fed the ethanol plus polyphenol diets. Liver transcriptome analysis revealed that the addition of the polyphenols suppressed the expression of the genes related to cell stress that were up-regulated by ethanol alone. Conversely, the polyphenols up-regulated the genes involved in bile acid synthesis, unsaturated fatty acid elongation, and tetrahydrofolate synthesis that were down-regulated by ethanol alone. Because parts of these genes were known to be regulated by the constitutive androstane receptor (CAR), we performed the same experiment in the CAR-deficient mice. As a result, fatty liver was observed not only in the ethanol group but also with the ethanol plus polyphenol groups. In addition, there was no segregation of the gene expression profiles among these groups. These results provide a molecular basis for the prevention of alcohol-induced stress by the polyphenols in alcoholic beverages.

Description
The aim of this study was to investigate the inhibitory effect of TSU68, a tyrosine kinase inhibitor of vascular endothelial growth factor receptor 2 (VEGFR2), platelet-derived growth factor receptor beta (PDGFR) and fibroblast growth factor receptor 1 (FGFR1), on colon cancer liver metastasis and to test the hypothesis that TSU68 modulates the microenvironment in the liver before the formation of metastasis.
Publication Title

Description
We describe GC-Tfr, a population of CD25 negative Foxp3 positive CXCR5hiPD1hiBCL6hi T-follicular regulatory cells that preferentially localise in the germinal centers. Male C57BL/6 Foxp3-DTR-GFP reporter mice were vaccinated with NP-Ova in Alum and 7 days later cells sorted before RNA-sequencing. Analysis revealed that GC-Tfr have a gene expression pattern equidistant between Tregs and Tfh, but fundamentally retain their suppressive characteristics as regulatory cells.

Description
T-follicular helper cells (Tfh) differentiate through a multistep process culminating in germinal center (GC) resident GC-Tfh that provide support to GC B-cells. T-follicular regulatory cells (Tfr) have been shown to have critical roles in the control of Tfh and germinal center formation. While Tfh cells are inhibited by IL-2, Treg cells depend on it. Here we describe a novel CD25 negative subset within both murine and human PD1+CXCR5+Foxp3+ Tfr that is preferentially located in the GC and can be clearly differentiated from non-GC Tfr, Tfh and effector Tregs by expression of a wide range of molecules. In comparison to Tfr and effector Tregs, GC-Tfr cells partially downregulate IL-2 dependent canonical Treg features, but retain suppressive function, while simultaneously upregulating genes associated with Tfh and GC-Tfh. We suggest that, similar to Tfh, Tfr follow a differentiation pathway culminating in a distinct GC resident subset, GC-Tfr.

Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
We have found that histone H2B is GlcNAcylated at residue S112 by O-GlcNAc transferase and that H2B S112 GlcNAcylation fluctuates in response to extracellular glucose level. We have also found that H2B S112 GlcAcylation promotes H2B K120 ubiquitination. To investigate whether these histone modification correlate to transcriptional activation, we performed comprehensive gene expression analysis using Affymetrix GeneChip in HeLa cell cultured with different conditions, i.e. without glucose, with glucose and with FBS.
