Description
The goal of the study was to identify the genes which are regulated by Interleukin-2 in the CD4+ T cells of the scurfy mice during regulatory T-cell deficiency. Scurfy (Sf) mice bear a mutation in the forkhead box P3 (Foxp3) transcription factor, lack regulatory T-cells (Treg), develop multi-organ inflammation, and die prematurely. The major target organs affected are skin, lungs, and liver. Sf mice lacking the Il2 gene (Sf.Il2-/-), despite devoid of Treg, did not develop skin and lung inflammation, but the inflammation in liver, pancreas, submandibular gland and colon remained. Genome-wide microarray analysis revealed hundreds of genes were differentially regulated among Sf, Sf.Il2-/-, and B6 CD4+ T-cells but the most changes were those encoding receptors for trafficking/chemotaxis/retention and lymphokines. Our study suggests that IL-2 controls the skin and lung inflammation in Sf mice in an apparent "organ-specific" manner through two novel mechanisms: by regulating the expression of genes encoding receptors for T-cell trafficking/chemotaxis/retention and by regulating Th2 cell expansion and lymphokine production. Thus, IL-2 is a master regulator for multi-organ inflammation and an underlying etiological factor for various diseases associated with skin and lung inflammation.

Description
The generation of sufficient numbers of mature ventricular myocytes for effective cell-based therapy is a central barrier for cardiac regenerative medicine. Here we demonstrate that induced pluripotent stem cells (iPSCs) can be derived from murine ventricular myocytes, and consistent with other reports of iPSCs derived from various somatic cell types, ventricular myocyte derived iPSCs (ViPSCs) exhibit a markedly higher propensity to differentiate into beating cardiomyocytes as compared to genetically-matched embryonic stem cells (ESCs) or iPSCs derived from tail-tip fibroblasts. Strikingly, ViPSC-derived cardiomyocytes form up to 99% ventricular myocytes suggesting that ventricular myocyte-derived iPSCs may be a viable strategy to generate specific cardiomyocyte subtypes for cell-based therapies. The enhanced ventricular myogenesis in ViPSCs is mediated via increased numbers of cardiovascular progenitors at early stages of differentiation. In order to investigate the mechanism of enhanced ventricular myogenesis from ViPSCs, we performed global gene expression and DNA methylation analysis, which revealed a distinct epigenetic signature that may be involved in specifying the ventricular myocyte fate in pluripotent stem cells.

Description
Chromosomal rearrangements involving ETS factors, ERG and ETV1, occur frequently in prostate cancer. We here examine mouse prostate cells from WT mice with s with T-ETV1 mice, which contains express the truncated human ETV1 under the endogenous Tmprss2 promoter. ETV1 expression can be tracked by GFP expression.

Description
Equine herpesvirus 1 (EHV-1) is the causative agent of a number of equine pathological states, including severe disease of the central nervous system, respiratory infections, and abortion storms. Our results showed that intranasal immunization with CpG-B oligodeoxynucleotides (ODN) protects CBA mice from lethal EHV-1 challenge. IFN-γ and seven interferon-stimulated genes (ISGs) were upregulated 39.4- to 260.3-fold at 8 h postchallenge in the lungs of RacL11-challenged mice that had been immunized with CpG-B ODN. Treatment with 20 ng/ml of IFN-γ reduced EHV-1 yield by 100-fold in MH-S at 4 days post-VZV infection compared to that of untreated cells. However, IFN-γ reduced virus yield by only 2-fold in and mouse fibroblast L-M cells. To identify IFN-γ-stimulated genes that inhibit EHV-1 replication, Affymetrix microarray analyses were performed with IFN-γ-treated MH-S and L-M cells. In MH-S cells, IFN-γ upregulated 551 genes and down-regulated 136 genes as compared to those of untreated cells. In L-M cells, IFN-γ upregulated 225 genes and downregulated 2 genes. Nine genes associated with innate immune response were significantly upregulated only in MH-S cells. Five antiviral ISGs MX1, SAMHD1, NAMPT, TREX1, and DDX60 were upregulated 3.2- to 18.1-fold only in MH-S cells. These results suggest that CpG-B ODN may be used as a prophylactic agent in horses.
