Expression profile of primary murine astrocyte-enriched cultures (AEC) exposed to oxygen-glucose deprivation

ABSTRACT: Microarray analysis was used to identify genes that fluctuated by oxygen-glucose deprivation of mouse astrocytes. Astrocyte-enriched cultures were generated from mixed glial cultures of mice and compared to control samples with 15 hours of oxygen-glucose deprivation. The results showed that 173 genes were upregulated with Fold change >10, P < 0.05. Both Nr4a1 and Nr4a3, which is an orphan nuclear receptor subfamily and known as an immediate early gene, were upregulated.

Expression data of mouse hematopoietic cells, Nr4a1/3 wild type and double mutant

Project description:We investigate the cellular and molecular mechanisms of tumor suppression by NR4A1 and NR4A3, and show a cell intrinsic essential function in maintenance of hematopoietic stem cell (HSC) homeostasis. In the absence of Nr4a1/3, HSC lost quiescence, became highly proliferative leukemia-stem cell (LSC) that transplanted AML to recipient mice. We further revealed that loss of NR4A1/3 leads to deregulated expression of the key cell cycle regulator Cdkn1c (P57), c-Myc oncogene, and glucose metabolic genes leading to enhanced aerobic glycolysis or Warburg effect in LSCs. Reintroduction of Nr4a1 in LSCs restored HSC quiescence, and reversed Nr4a1/3 deficiency induced P57 suppression and c-Myc overexpression. Collectively, we identify an essential role of Nr4a1/3 in coordinately regulating cell cycle entry and glucose metabolism to prevent uncontrolled stem cell proliferation and AML transformation. These results have major implications for designing therapeutic strategies in AML. To identify NR4A-dependent molecular signaling pathways that may control HSC homeostasis, we performed genome-wide transcript profiling of Lin-Sca1+ (LS) cells from WT and DKO mice. For Affymetrix analysis, we generated three independent pools of RNA from sorted LS cells from 10-20 WT or DKO (2- to 3-week-old) mice per sample.

Collectively, we identify an essential role of Nr4a1/3 in coordinately regulating cell cycle entry and glucose metabolism to prevent uncontrolled stem cell proliferation and AML transformation.

Siah2-dependent gene expression profile

Project description:Gene expression profiling was performed to identify Siah2-dependent changes in cells subjected to ER stress, hypoxia, and combined glucose/oxygen deprivation. To establish the magnitude of the Siah2 effect on the ER stress response, we have compared gene expression profiles of WT and Siah1a-/-::Siah2-/- mouse embryo fibroblasts (MEFs) that were subjected to glycosylation inhibitor tunicamycin (TM), thapsigargin (TG), glucose deprivation, or glucose/oxygen deprivation. Overall, this analysis confirmed changes associated with ER stress that had not previously been associated with Siah2 signaling, substantiating Siah2 as a key coordinator of ER stress through the ATF4 and sXbp1 pathways. WT and Siah1a/Siah2 KO MEF cells were treated with TM or TG for 6 h, or subjected for 12 h to oxygen deprivation, glucose deprivation or a combination of oxygen and glucose deprivation, in duplicate.

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.

PHD inhibition upregulates glycolytic pathway in OGD

Project description:To elucidate the mechanism of enarodustat pretreatment-induced protection against oxygen-glucose deprivation (OGD), we have we have employed whole genome microarray expression profiling as a discovery platform to identify genes upregulated by enarodustat exposure. HK2 cells were pretreated with either vehicle (DMSO) or enarodustat for 24 hours prior to OGD for 16 hours. Pathway analysis revealed upregulated glysolysis pathway.
