Description
Specific deletion of suppressor of cytokine signaling 3 (Socs3) in keratinocytes can cause severe skin inflammation with infiltration of immune cells, however the molecular mechanisms and key regulatory pathways involved remains poorly understood. To investigate the role of Socs3 in keratinocytes, we generated and analyzed global RNA-Seq profiles in Socs3 conditional knockout (cKO) mice at two different stages (2- and 10- weeks). Over 400 shared genes were found to be significantly regulated at both time points. Two week samples were marked by initial skin barrier dysfunction established by the downregulation of keratin associated genes and upregulation of genes regulating lipid metabolism. Subsequent increase in expression level of multiple chemokines and cytokines at 10 week were observed representing response to skin inflammation caused by the disruption of skin barrier function. A group of activator protein-1 related genes were to found to be highly elevated in Socs3 cKO mice at both time points. This observation was duly validated using qRT-PCR in Socs3 depleted human keratinocyte–derived HaCaT cells. Overall this study reveals an important regulatory dynamics of Socs3 in skin barrier dysfunction. Overall design: Socs3 cKO mice mRNA profiles of 2 and 10 week wild type (WT) C57BL/6 mice were generated by sequencing using HiSeq 1000 system (Illumina) machine which could read a 50 bp sequence.

Description
Activation of telomerase often endows cancer cells, but rarely normal somatic cells, with immortality. Especially, fetal lung fibroblasts are known to be hardly immortalized by TERT overexpression. We here established an immortal non-transformed lung fibroblast cell line only by TERT transfection, as well as an immortal transformed cell line by transfection of TERT and SV40 early antigens. Comparing the expression profiles of these cell lines with those of mortal cell strains with elongated lifespan after TERT transfection, 51 genes, including 19 upregulated and 32 downregulated, were explored to be the candidates responsible for regulation of cellular proliferation of lung fibroblasts. These included the genes previously reported to be involved in cellular proliferation, transformation, or self-renewal capacity, and those highly expressed in lung tissues obtained from patients with idiopathic pulmonary fibrosis or hypersensitivity pneumonitis. This set of lung fibrobrast cell lines/strains of identical genetic background with different proliferative capacity, mortal and immortal non-transformed fibroblasts may become useful model cells for research on lung fibroblast growth regulation and the candidate genes explored in this study may provide promising biomarkers or molecular targets of pulmonary fibrosis.

Description
Deregulated retinal angiogenesis directly cause vision loss in many ocular diseases, such as diabetic retinopathy and retinopathy of prematurity. To identify endothelial-specific genes expressed in angiogenic retinal vessels, we purified genetically labeled endothelial cells from Tie2-GFP transgenic mice and performed gene expression profiling using DNA microarray. To find out genes associated with angiogenesis, comparisons of microarray data were carried out between GFP-negative non-endothelial retinal cells and GFP-positive retinal endothelial cells in angiogenic P8 retina.

Description
Several clinical trials have shown anti-CD3 treatment to be a promising therapy for autoimmune diabetes, but its mechanism of action remains unclear. Foxp3+ regulatory T (Treg) cells are likely to be involved, and we have shown a strong effect of anti-CD3 on homeostatic control of CD4+ FoxP3+ regulatory T (Treg) cells. To analyze the early consequences of anti-CD3 treatment, we sorted and profiled Treg and conventional CD4+ T (Tconv) cells in the first hours and days after anti-CD3 treatment of NOD mice. In practice, NOD mice carrying the Foxp3-GFP reporter were treated with anti-CD3 mAb KT3 (50 ug iv) and CD4+ T cells were sorted from pooled spleen and lymph nodes after 2, 8, 24 and 72 hrs, separating Treg and Tconv cells on the basis of GFP expression. Anti-CD3 treatment led to a transient transcriptional response, terminating faster than most antigen-induced responses. Most transcripts were similarly induced in Treg and Tconv cells, but several were differential, in particular those encoding the IL7 receptor (IL7R) and transcription factors Id2/3 and Gfi1, upregulated in Treg but repressed in Tconv cells. In parallel experiments, we tested the effect of soluble anti-CD3 added to cultures of fresh splenocytes, sorting Treg and Tconv cells at the same time points. Many of the anti-CD3 elicited changes, and of the differential response observed in vivo, were also observed in vitro. Two independent replicate series; Treg and Tconv samples abbreviated TR and TC, respectively. Keywords: Transcriptional activation, TCR

Description
Previously, we have shown that an AP-1 family member Fra-2, which is hardly expressed in normal mature T cells, is consistently over-expressed in adult T-cell leukemia/lymphoma (ATLL), and together with JunD, upregulates CCR4 and many other genes including proto-oncogenes c-Myb, MDM2, Bcl-6, and SOX4. SOX4 is frequently overexpressed in many solid tumors and considered to be a potential oncogene.
