Illumina HiSeq 2000
Description
Initially, ATL cell lines (MT-1 or KK-1) were stably transfected with reporter plasmid for HTLV-1 Tax expression, and single clones were isolated . This reporter in composed of Tax responsive element upstream of d2EGFP fluorescent protein. d2EGFP is expressed upon Tax expression in any individual cell. To compare transcriptomes of Tax(-) and Tax(+) cells, FACS sorting was done for d2EGFP(-) and d2EGFP(+) populations and RNA sequencing was performed. Overall design: Two ATL reporter cell lines were used in this study (MT1GFP and KK1GFP). For Each cell line, two samples were analyzed: d2EGFP(-) and d2EGFP(+). In total 4 samples were used in this study.
Publication Title

Description
We previously reported that human T cell lymphotropic virus 1 (HTLV-1) Tax oncoprotein constitutively activates TAK1. Here, we established Tax-positive HuT-102 cells stably downregulated TAK1 expression by short-hairpin RNA (HuT-shTAK1 cells), and investigated the physiological function of TAK1. Microarray analysis demonstrated that several interferon (IFN)-inducible genes including chemokines such as CXCL10 and CCL5 were significantly downregulated in HuT-shTAK1 cells. In contrast, Tax-mediated constitutive activation of NF-kB was intact in HuT-shTAK1 cells. IRF3, a critical transcription factor in innate immunity to viral infection, was constitutively activated in a Tax-dependent manner. Activation of IRF3 and IRF3-dependent gene expression were dependent on TAK1 and TBK1. On the other hand, IRF4, another IRF family of transcription factor overexpressed in a Tax-independent manner, negatively regulated the TAK1-dependent IRF3 transcriptional activity. Together, HTLV-1 manipulates IFN signaling by regulating both positive and negative IRFs.

Description
Cardiovascular complications are the leading cause of death in autosomal dominant polycystic kidney disease (ADPKD), and intracranial aneurysm (ICA) causing subarachnoid hemorrhage is among the most serious complications. The diagnostic and therapeutic strategies for ICAs in ADPKD have not been fully established. We here generated induced pluripotent stem cells (iPSCs) from seven ADPKD patients, including four with ICAs. The vascular cells differentiated from ADPKD-iPSCs showed altered Ca2+ entry and gene expression profiles compared with those from control-iPSCs. We found that the expression level of a metalloenzyme gene, matrix metalloproteinase (MMP) 1, was specifically elevated in the iPSC-derived endothelia from ADPKD patients with ICAs. Furthermore, we confirmed a statistically significant correlation between the serum MMP1 levels and the development of ICAs in 354 ADPKD patients, indicating that the serum MMP1 levels may be a novel risk factor and become more beneficial when combined with other risk factors. These results suggest that cellular disease models with ADPKD-specific iPSCs can be used to study the disease mechanisms and to identify novel disease-related molecules or risk factors.
