View SamplesPRR5 transcription factor acts in the circadian clock system. To elucidate regulated genes by PRR5, Chimeric protein PRR5-VP, which activates direct target genes of PRR5, was over-expressed in Col-0. Microarray analsysis was performed using these plants with Affymetrix ATH1 genechip.
Transcriptional repressor PRR5 directly regulates clock-output pathways.

Transcription factor Zeb2 regulates commitment to plasmacytoid dendritic cell and monocyte fate.

View SamplesRecent studies have identified Zeb2 as a transcription factor important for the final maturation of natural killer cells and effector CD8+ T cells. We show that Zeb2 is required for the development of two myeloid cell types, the monocyte and the plasmacytoid dendritic cell, and clarify that this factor is not required for the development of classical dendritic cells.

View SamplesLysine 9 di-methylation and lysine 27 tri-methylation of histone H3 (H3K9me2 and H3K27me3) are mostly linked to gene repression. However, functions of repressive histone methylation dynamics during inflammatory responses remain poorly understood. Here, we show that lysine demethylase 7A (KDM7A) and 6A (UTX) are rapidly transported to nuclear factor kappa-B (NF-?B) related elements in human endothelial cells in response to tumor necrosis factor (TNF)-a. KDM7A and UTX demethylate H3K9me2 and H3K27me3, respectively, and cooperatively activate NF-?B dependent inflammatory genes. Furthermore, using both in situ Hi-C and other 3C based technology, loops between super enhancers (SEs) are newly formed following TNF-a-stimuli at NF-?B-dependent inflammatory loci where KDM7A- and UTX-recruitment coincide. Collectively, these findings suggest that erasing of repressive histone marks by KDM7A and UTX within NF-?B-related elements might functionally associate with formation of SE-SE three-dimensional interactions and could be a cue signal during inflammatory responses in human endothelial cells. Overall design: Total 29 samples were derived from [1] HUVECs in the absence or presence of TNF-alpha (0, 4, and 24 hrs) to determine TNF-alpha-responsive genes during inflammation, [2] si control, siKDM7A, siUTX, or siKDM7A+siUTX transfected HUVECs under TNF-alpha-stimuli (4 hrs) to understand molecular function of KDM7A and UTX during inflammation.
Coordinated demethylation of H3K9 and H3K27 is required for rapid inflammatory responses of endothelial cells.

View SamplesBy using a genetically accurate mouse model, we demonstrate that endogenous expression of oncogenic N-RasG12D and Tet2 haploinsufficiency collaborate to accelerate CMML development in mice. Gene expression was compared across all genotypes (WT, Tet2+/-, NrasG12D/+ and double mutants) in bone marrow-derived hematopoietic stem cells (CD150+CD48-Lin-Sca1+cKit+) using RNA-seq. N-RasG12D and Tet2 haploinsufficiency cooperate to induce both unique and overlapping effects on HSC gene expression programs. Overall design: Gene expression profiling in FACS-sorted SLAM HSCs from 10-12 week old wild type control (n=3), NrasG12D/+ single mutant (n=3), Tet2+/- single mutant (n=3) and NrasG12D/+;Tet2+/- double mutant (n=3) mice.
Oncogenic N-Ras and Tet2 haploinsufficiency collaborate to dysregulate hematopoietic stem and progenitor cells.

View SamplesUsing wild type and Ash1l deltaSET mutant embryonic stem cells, here we report differences of gene expression pattern under undifferentiated state and differentiated state. Interestingly, gene expression changes are frequently observed in a subset of gene group that is regulated by Polycomb group proteins. Overall design: Examination of 2 cell types in 2 different conditions.
