Fibroblasts can be directly reprogrammed into cardiomyocyte-like cells (iCMs) by overexpression of cardiac transcription factors or microRNAs. However, induction of functional cardiomyocytes is inefficient, and molecular mechanisms of direct reprogramming remain undefined. Here, we demonstrate that addition of miR-133a (miR-133) to Gata4, Mef2c, and Tbx5 (GMT) or GMT plus Mesp1 and Myocd improved cardiac reprogramming from mouse or human fibroblasts by directly repressing Snai1, a master regulat ...[more]
Project description:Global gene expression profile of total 24460 probes in the iCMs. The gene expression shifts from a fibroblast state toward a cardiac-like phenotype by Gata4/Mef2c/Tbx5/Mesp1/Myocd (GMTMM) or GMTMM/miR-133 transduction at 7 days after transduction. MiR-133 silenced fibroblast signatures in parallel with cardiac gene activation, and Snai1 overexpression inhibited the effects of miR-133-mediated cardiac reprogramming. HCFs were used for negative control, human heart tissue for positive control. Gene expression profiles were compared among HCFs, iCMs and heart. 24460 probes were analyzed in each experiment.
Project description:Global gene expression patterns of the iCMs shift from a MEF state toward a cardiac-like phenotype by Gata4/Mef2c/Tbx5 (GMT) or GMT/miR-133 transduction at 3, 7 and 18 days after transduction (D3, D7 and D18) MiR-133 silenced fibroblast signatures in parallel with cardiac gene activation, and Snai1 overexpression inhibited the effects of miR-133-mediated cardiac reprogramming. MEFs were used for negative control, mouse heart tissue for positive control. Gene expression profiles were compared among MEFs, iCMs and heart. 23474 probes were analyzed in each experiment.
Project description:The screening of putative candidate genes downstream of IL7R-INS in vitro KSL/CLP and in vivo (depicted as B-neoplasm, Notch-T-ALL, or myeloid disorder) in comparison to WT. Five-condition experiment: WT-KSL vs. INS-KSL cells; WT-CLP vs.INS-CLP; WT/ICN vs. INS/ICN; WT-CMP vs. INS-CMP. Biological replicate: each 1, One replicate per array.
Project description:To identify molecular biomarkers that are useful for diagnosis and its targeting treatment, we analysed expression profile of synovial sarcoma tissue. In the present study, we studied gene expression profiles comparing 11 cases of synovial sarcoma.
Project description:To identify molecular biomakers that are useful for diagnosis and its targeting treatment, we compared the gene expression profile of myxiod liposarcoma with that of normal fat tissue. In the present study, we studied about gene expression profiles comparing 6 non-preoperative myxoid liposarcoma with 3 normal fat tissue.
Project description:Comprehensive gene expression analysis in BM-resident stromal cells was performed for an overview of BM environmental change caused by total body irradiation (TBI). Total RNA samples collected from BM-resident stromal cells with or without TBI were subjected to high sensitivity DNA microarray assays Three-condition experiment: Unirradiated, 1 day after TBI and 3 days after TBI. Bone marrow stromal cells were obtained from C57BL/6 mice (n = 6) either non-irradiated or after 9.5 Gy irradiation at indicated times.
Project description:The change of mRNA expression in murine immortalized podocyte were analyzed after miR-26a silencing. These results provide a basical information of molecular pathology in podocyte biology. Mouse podocytes immortalized by temperature sensitive SV40 were used. Podocyte cultures grown at 33 °C were trypsinized and then cultured with RPMI-1640 without antibiotics in 24-well plates at 60–70% confluence for 2 days. On day 3, an anti-miR negative control (40 pmol) or the miR-26a miRNA inhibitor (40 pmol) was transfected to podocytes. The cells were analyzed after culturing for 24 hour.
Project description:Transcriptional profiling of left ventricular tissues of Dahl rat with or without treatment of chaetocin Three-condition experiment, Control vs. failing heart, failing heart vs. treatment with chaetocin. 3 samples mixture per each group
Project description:Transcriptional profiling of mouse osteoclasts comparing control osteoclasts from Stat5 flox mice with osteoclasts from Stat5 cKO mice. Two-condition experiment, Stat5 flox cells vs. Stat5 cKO cells
Project description:To elucidate the molecular features of craniofacial versus trunk neural crest cells (NCCs), we utilized P0-Cre/Floxed-EGFP mice that specifically label NCCs (Yamauchi et al., 1999 (PMID 10419695)). Craniofacial and trunk regions were isolated from P0-Cre/Floxed-EGFP mouse embryos at embryonic day E12.5, and dissociated cells were analyzed by flow cytometory in regard to the intensity of EGFP. In this study, we performed at least duplicate experiments for each of the four groups (Craniofacial EGFP+, Trunk EGFP+, Craniofacial EGFP-, Trunk EGFP-). Total of 9 samples.
