Description
Purpose: The cholinergic anti-inflammatory pathway (CAP) links the nervous and immune systems and modulates innate and adaptive immunity. The goals of this study are to identify the new downstream signaling of a7nAChR in macrophages. Methods: Peritoneal macrophages isolated from a7nAChR+/+ and a7nAChR-/- mice were treated with nicotine (10 µM) and/or LPS (100 ng/ml), then RNA-seq was performed. Results: Genes were selected that had more than 4-fold relative gene expression in nicotine-treated cells compared to the control group (vehicle-treated). The same calculation was applied to nicotine+LPS-treated cells and LPS-treated cells and 264 genes were identified as genes commonly induced by nicotine based on these two comparisons. Then relative gene expression was compared between a7nAChR+/+- and a7nAChR-/- -derived cells. 18 genes were finally selected whose expressions are suppressed (<1/2) in a7nAChR-/- -derived peritoneal macrophages. Conclusions: Our study represents the first detailed analysis focused on the new downstream signaling of a7nAChR in macrophages, generated by RNA-seq technology. We newly revealed the important anti-inflammatory role of Hes1 in the CAP using some functional experiments. Overall design: Peritoneal macrophage's mRNA profiles of wild type (WT) and a7nAChR-/- mice treated with Nicotine and/or LPS were generated by deep sequencing.

Description
Lysine 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.

Recently the role of PPAR/ in angiogenesis has been revealed, and we hypothesized that the crosstalk between hypoxia and PPAR/ on endothelial cells may exsist. To elucidate the interaction between two signalings, we report the comprehensive change of transcripts induced by PPAR/ agonist (GW501516) and/or hypoxia.

3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, statins, are known to exert endothelial athero-protective effects through the induction of specific transcriptional factors and their downstream target genes besides lowering LDL-cholesterol.

Description
Many neural progenitor cells present in the fetus, but also in adult brain, which play a major role for the reproduction for healingin regeneration of neuronal cells, when differentiated cells are damaged. However, effects of radiation effect on undifferentiated neural progenitor cells remained unclear. The radiation doses of medical exposure, pollution by nuclear power plant accidents, and other exposure of workers; medical workers, airline crews, and astronaut have been focused. In this study, we report the effects of low- to middle- dose doses of radiation on cultured human neural progenitor cells (hNPC) differentiated derived from embryonic stem (ES) cells, which are partially compared with those of human umbilical vein endothelial cell (HUVEC).
