Effect of NR4A3 siRNA treatment on gene expression of islet derived hybrid cell of 1.1B4

ABSTRACT: Gene regulation associated with antioxidant defense system in pancreatic beta cells still needs to be elucidated, we found NR4A3 gene expression was up-regulated with 100mM H2O2, therefore, we analyzed the genes expression with Agilent micro-array after NR4A3 siRNA4 treatment by one color method, and found 1044 genes were up-regulated and 859 genes were down regulated in NR4A3 knocked down cell. Changes of some genes expressions were confirmed by real time PCR. The genes of 1044 in NR4A3 siRNA treated cell were up-regulated over 2 folds and 859 genes were down-regulated under 0.67 folds compared with control sample.

The orphan nuclear receptor NR4A3 is involved in the function of dendritic cells

Project description:Transcriptome analysis of LPS-stimulated bone marrow-derived dendritic cells with NR4A3 gene silencing The NR4A3/NOR1 belongs to the NR4A subfamily of the orphan nuclear hormone receptor superfamily, which is activated in a ligand-independent manner. To examine the role of NR4A3/NOR1 in gene expression of dendritic cells (DCs), we introduced NR4A3 siRNA into bone marrow-derived DCs (BMDCs) and determined the expression levels of mRNA and proteins of cytokines, cell surface molecules, NFκB signaling-related proteins, and transcription factors. The expression level of NR4A3 was markedly up-regulated by TLRs-mediated stimulation in DCs. NR4A3 knockdown significantly suppressed LPS, CpG, or poly I:C-mediated up-regulation of CD80, CD86, IL-10, IL-6, and IL-12. Proliferation and IL-2 production levels of T cells co-cultured with NR4A3-knocked down DCs were significantly lower than that of T cells co-cultured with control DCs. Furthermore, the expression of IKKβ, IRF4, and IRF8 was significantly decreased in NR4A3 siRNA-introduced BMDCs. The knockdown experiments using siRNAs for IKKβ, IRF4, and/or IRF8 indicated that LPS-induced up-regulation of IL-10 and IL-6 was reduced in IKKβ knocked down cells, and that the up-regulation of IL-12 was suppressed by the knockdown of IRF4 and IRF8. Taken together, these results indicate that NR4A3 is involved in TLR-mediated activation and gene expression of DCs.

Effect of H2O2 treatment on gene expression of islet derived hybrid cell of 1.1B4

Project description:We analyzed the comprehensive gene expression changes by H2O2 in pancreatic beta-cell derived 1.1B4 cells using Agilent microarray. The genes of 2903 H2O2 treated were up-regulated and 2283 genes were down-regulated compared with control sample. HMOX1, EGR1, IGF, IL8 and NR4A3 were strongly up-regulated Gene regulation associated with antioxidant defense system in pancreatic beta cells still needs to be elucidated, we analyzed the genes expression with Agilent micro-array after 4 hours of 100mM H2O2 treatment by one color method, and found 2903 genes were up-regulated and 2283 genes were down regulated. Changes of some genes expressions were confirmed by real time PCR.

Transcriptional profiling of monocytes deficient in Nuclear Orphan Receptors NR4A2 and NR4A3 reveals distinct signalling roles related to antigen presentation and viral response.

Project description:Using RNA-sequencing and strategic bioinformatic analysis we investigated the down-stream effects of NR4A2 and NR4A3 in monocytes and dissected their common and distinct signalling roles.NR4A2 selective genes were most associated with antigen presentation, NR4A3 selective genes were most associated with interferon/viral reponse and NR4A2/3 co-regulated genes were most associated with clasical innate immure response signaling e.g. TLR signaling and chemokine secretion.

Transcriptome sequencing data analysis of Bacillus subtilis NCIB 3610 wild-type strain, tmRNA mutant strain and MB revertant strain

Project description:In our study, we found that lack of tmRNA affects the biofilm formation in Bacillus subtilis, which has important research significance. Then, we obtained a revertant strain MB from tmRNA mutant strain. And MB strain could restore biofilm production capacity. Therefore, the transcriptomes of the three strains were sequenced. Based on the statistical analysis of gene expression (P < 0.05), there were 756 genes up regulated while 992 genes down regulated by at least two folds when comparing TM to WT. Secondly, there were 974 genes up regulated while 563 genes down regulated by at least two folds when comparing MB to TM. And there were 179 genes up regulated while 307 genes down regulated by at least two folds when comparing MB to WT.

NR4A3 plays a pivotal role in the differentiation of monocyte-derived dendritic cells

Project description:The molecular requirements that guide the differentiation of monocytes into macrophages or monocyte-derived dendritic cells (Mo-DCs) are poorly understood. Here, we demonstrate that the nuclear orphan receptor NR4A3 guides monocyte fate and is essential for Mo-DC differentiation. Nr4a3-/- mice are impaired in the in vivo generation of DC-SIGN+ Mo-DCs following LPS stimulation and, as such, are defective at priming a CD8+ T cell response to gram negative bacteria. We also demonstrate that NR4A3 is an essential downstream effector of IRF4 during in vitro differentiation of Mo-DCs with GM-CSF and IL-4 and that, in absence of NR4A3, monocytes are diverted to macrophages. Our transcriptomic analysis of the genes regulated by NR4A3 reveals that the acquisition of the Mo-DC differentiation program is intertwined with the acquisition of a migratory signature. Furthermore, NR4A3 is critical for steady-state migration of non-lymphoid tissue conventional DCs to lymph nodes. Altogether, our results highlight a unique role for NR4A3 in Mo-DC differentiation and in the acquisition of migratory properties.

Project description:We used microarray analysis to examine transcriptomic changes in cdm1 mutant, identifying genes potentially regulated by CDM1 by comparing gene expression between cdm1 and wild type young floral buds. Among 375 genes that showed differential expression (P-value <0.05) with >1.5-fold changes between wild type and cdm1, 185 genes were down-regulated by 1.5 to 7.10-folds, whereas 190 genes were up-regulated by 1.5 to 5.82-folds.

Effect of depletion of NR4A3 on vascular calcification [CUTtag_H3K18LA]

Project description:Medial arterial calcification is a chronic systemic vascular disorder distinct from atherosclerosis and is commonly observed in patients with chronic kidney disease (CKD), diabetes mellitus, and aging individuals. We previously showed that orphan nuclear receptor NR4A3 is a key regulator in the progression of apolipoprotein (apo) A-IV-induced atherosclerosis; however, little is known about its role in vascular calcification. NR4A3 expression was upregulated in calcified aortic tissues from CKD mice or 1,25(OH)2VitD3 overload-induced mice, and in human calcified aorta. NR4A3 deficiency preserved VSMCs contractile phenotype, inhibited the expression of osteoblast differentiation-related genes, and reduced calcium deposition in the vasculature.

Nr4a1 and Nr4a3 upregulate cell cycle genes upregulated in the Nkx6.1 beta-cell proliferation pathway

Project description:Loss of functional beta-cell mass is a hallmark of Type 1 and Type 2 diabetes, and methods for restoring these cells are needed. Nkx6.1 induces beta-cell proliferation, but the pathway by which Nkx6.1 activates beta-cell expansion has not been defined. Here we demonstrate that Nkx6.1 induces expression of the Nr4a1 and Nr4a3 orphan nuclear receptors, and that these factors are both necessary and sufficient for Nkx6.1-mediated Î²-cell proliferation. Overexpression of the Nr4a receptors results in increased expression of key cell cycle inducers E2F1 and cyclin E1. Furthermore, Nr4a receptors induce components of the anaphase-promoting complex, including Ube2c. We set up a microarray using primary rat islets that were left untreated or transduced with adenoviruses overexpressing GFP, Nr4a1 or Nr4a3 for 48 h.
