Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Dorsomorphin is a small molecule inhibitor of type I bone morphogenic protein receptors (BMPRs). We have found that dorsomorphin affects a wide range of T cell function. In order to obtain the bigger picture of the effects of DM in T cell activation. transcriptomic analysis was performed using mouse primary CD25-CD4+ T cells with either DM (4 M) or vehicle in the presence or absence of stimulation by anti-CD3 and -CD28 antibodies.

Description
Tamoxifen, a selective estrogen receptor modulator, is widely used in research and clinically in patients. Tamoxifen injection (3 consecutive days, intraperitoneal, 5mg/20g mouse body weight) causes dramatic rearrangement of the gastric mucosa with loss of > 90% of PCs, a 6-fold increase in proliferation in stem/progenitor cells, and morphological changes in the ZCs in the bases of gastric-units.

Description
The fields of drug discovery and regenerative medicine require large numbers of adult human primary hepatocytes. For this purpose, it is desirable to use hepatocyte-like cells (HLCs) differentiated from human pluripotent stem cells. To develop an efficient HLCs induction method, we constructed a red fluorescent reporter, CYP3A7R, in which DsRed is placed under the transcriptional regulation of CYP3A7 coding for a human fetus-type P450 enzyme. We created transgenic mice using mouse embryonic stem cells (mESCs) carrying a CYP3A7R transgene.
Publication Title
Real-time fluorometric evaluation of hepatoblast proliferation in vivo and in vitro using the expression of CYP3A7 coding for human fetus-specific P450.

Description
Using microcell-mediated chromosome transfer (MMCT) into the mouse melanoma cell line, B16F10, we have previously found that human chromosome 5 carries a gene, or genes, that can negatively regulate TERT expression. To identify the gene responsible for the regulation of TERT transcription, we performed cDNA microarray analysis using parental B16F10 cells, telomerase negative B16F10 microcell hybrids with a human chromosome 5 (B16F10MH5), and its revertant clones (MH5R) with reactivated telomerase. Here we report the identification of PITX1, whose restoration leads to the downregulation of mouse tert (mtert) transcription, as a TERT suppressor gene. Additionally, both human TERT (hTERT) and mouse TERT (mtert) promoter activity can be suppressed by PITX1. We showed that three and one binding sites, respectively, within the hTERT and mtert promoters that express a unique conserved region are responsible for the transcriptional activation of TERT. Furthermore, we showed that PITX1 binds to the TERT promoter both in vitro and in vivo. Thus, PITX1 suppresses TERT transcription through direct binding to the TERT promoter, which ultimately regulates telomerase activity.

Description
Cholesteatoma arises from a tympanic membrane and expands in the middle ear. It erodes the surrounding bone and leads to hearing loss or brain abscess which is lethal complication. Currently, the only effective treatment is the complete surgical removal of cholesteatoma. However, possibility of recurrence is not satisfactory, other clinical treatment is desired. A mechanism of bone erosion in rheumatoid arthritis, which is one of the bone destructive disease, is progressing to be clarified. Receptor activator of NF-?B ligand (RANKL) secreted by synovial fibroblasts, T cells, and B cells lead to differentiation and activation of osteoclast precursor in rheumatoid arthritis. In contrast it has been still unclear why cholesteatoma erodes bone. In the current study we studied that osteoclasts statistically increased in cholesteatoma, and that fibroblasts in the prematrix of cholesteatoma express RANKL. In this study we studied that osteoclasts statistically increased in cholesteatoma, and that fibroblasts in the prematrix of cholesteatoma express RANKL. We investigated upstream of RANKL from RNA sequence results by Ingenuity Pathways Analysis, which is data base of abundance information about molecular biology. Overall design: To generate the transcriptome profiles of the permatrix of cholesteatoma and dermis cut by laser micro dissection from cholesteatoma, three pairs of both sample from the same patients were adapted to RNA sequencing.

Description
Analysis of Foxp3(+)epigenetics(-) T cells, Foxp3(-)epigenetics(+) T cells, and Foxp3(+)epigenetics(+) T cells. Results indicate regulatory T cell (Treg) ontogenesis requires two independent processes, expression of the transcription factor Foxp3 and establishment of Treg epigenetic programs induced by T cell receptor (TCR) stimulation.
Publication Title
T cell receptor stimulation-induced epigenetic changes and Foxp3 expression are independent and complementary events required for Treg cell development.

Description
Werner syndrome (WS) is a premature aging disorder characterized by chromosomal instability and cancer predisposition. Mutations in WRN are responsible for the disease and cause telomere dysfunction, resulting in accelerated aging. In the present study, we describe the effects of long-term culture on WS iPSCs, which acquired and maintained infinite proliferative potential for self-renewal over 2 years. After long-term cultures, WS iPSCs exhibited stable undifferentiated states and differentiation capacity, and premature upregulation of senescence-associated genes in WS cells was completely suppressed in WS iPSCs despite WRN deficiency.
Publication Title
Reprogramming suppresses premature senescence phenotypes of Werner syndrome cells and maintains chromosomal stability over long-term culture.
