RNA-seq of human brain endothelial cells treated with Nrf2 activator RTA-404

ABSTRACT: Systemic inflammation can lead to a compromised blood-brain barrier (BBB) and neuro-inflammation, with acute consequences such as delirium, and long-lasting deleterious effects including cognitive decline and the exacerbation of neurodegenerative disease progression. Previous studies have shown beneficial roles of Nrf2 in the development and homeostastis of endothelial cells, an integral component of the BBB. We performed RNA-seq on human brain endothelial cells, in a control condition and treated with RTA-404 (CDDO-TFEA), a potent stimulator of Nrf2.

Transcription profiling of mouse Keap1-null (CKO) to investigate genetic and pharmacologic activation of Nrf2 signaling

Project description:Genetic versus chemoprotective activation of Nrf2 signaling: overlapping yet distinct hepatic gene expression profiles between Keap1 knockout and triterpenoid treated mice; Loss of Nrf2 signaling increases susceptibility to acute toxicity, inflammation, and carcinogenesis in mice due to the inability to mount adaptive responses. By contrast, disruption of Keap1 (a cytoplasmic modifier of Nrf2 turnover) protects against these stresses in mice; although dominant negative mutations in Keap1 have been identified recently in some human cancers. Global characterization of Nrf2 activation is important to exploit this pathway for chemoprevention in healthy, yet at-risk individuals and also to elucidate the consequences of hijacking the pathway in Keap1-mutant human cancers. This analysis also enables a global characterization of the pharmacodynamic action of CDDO-Im at a low dose that is relevant to chemoprevention. Experiment Overall Design: Liver-targeted conditional Keap1-null (CKO) mice provide a model of genetic activation of Nrf2 signaling. By coupling global gene expression analysis of CKO mice with analysis of pharmacologic activation using the synthetic oleanane triterpenoid CDDO-Im, we are able to gain insight into pathways affected by Nrf2 activation. CDDO-Im is an extremely potent activator of Nrf2 signaling. CKO mice were used to identify genes modulated by genetic activation of Nrf2 signaling. The CKO response was compared to hepatic global gene expression changes in wild-type mice treated with CDDO-Im at a maximal Nrf2 activating dose. n=3/group, male 9 week old mice were used. Mice were treated with a single dose of vehicle (10% Cremophor-EL, 10% DMSO, and PBS) or 30 umol CDDO-Im/kg body weight by gavage and sacrificed 6 h later.

RNA-seq of endothelial cells, astrocytes and microglia in wild-type and endothelial cell-specific Nrf2 knockout mice, in a model of systemic inflammation

Project description:Systemic inflammation can lead to neuro-inflammation with both acute consequences and long-lasting deleterious effects, such as cognitive decline and the exacerbation of neurodegenerative disease progression. We investigated the role in regulating this process of the activation of the transcription factor Nrf2 in brain endothelial cells.

Comparative gene expression analysis of Nrf2 activators, CDDO-Im, CDDO-Me and dimethyl fumarate (DMF) in VC1 lung cancer cells

Project description:Nrf2 is an important therapeutic target as activation of this pathway detoxifies harmful insults and reduces oxidative stress. However, the role of Nrf2 in cancer biology is controversial. Protection against oxidative stress and inflammation can confer a survival advantage to tumor cells, leading to a poor prognosis, and constitutive activation of Nrf2 has been detected in numerous tumors. In our study, we examined the role of two clinically relevant classes of Nrf2 activators, the synthetic triterpenoids (CDDO-Im and CDDO-Me) and dimethyl fumarate (DMF) in lung cancer. Using microarrays, we attempt to examine whether these Nrf2 activators have an effect on the same subset of Nrf2 genes.

Transcriptome Kinetics of 1[2-cyano-3,12-dioxooleana-1,9(11)-dien-28-oyl] imidazole (CDDO-Im) in Human Umbilical Vein Endothelial Cells (HUVEC): Mechanism of Action of Cytoprotection

Project description:This study evaluated temporal gene expression profiles to better characterize the early transcriptional events and their relationship to the dynamics of the cytoprotective response in human umbilical vein endothelial cells (HUVEC) to CDDO-. Time-course gene expression profiling was performed on HUVEC treated with CDDO-Im for 0.5, 1, 3, 6, and 24 hours.

Transcription profiling of lymphatic endothelial cell subtypes expressing high and low levels of podoplanin

Project description:We microprepared native mammary skin resections from healthy female donors (breast size reduction) by a combination of enzymatic and mechanical treatment. The resulting suspensions of single dermal cells were then subjected to FACSorting using antibodies against the lymphovascular marker protein podoplanin and the panendothelial protein CD31 as positive and the leukocytic protein CD45 as negative markers. We aimed at separating lymphatic vascular endothelial cells (LECs) from blood vascular endothelial cells (BECs) in order to characterize their moelcular and functional phenotypes in health and disease. We found that lymphatic endothelial cells consisted of two instead of only one cell population. Their discrimination marker was high versus low expression of podoplanin surface protein, respectively. Especially, the low-podoplanin expressors were undescribed. Thus, we screened for their transcription profile using U133A. We identified specific marker genes and finally have assigned a specific function to the novel LEC subpopulation unknown up to now. Importantly, we did not use lysates from cell culture, but from ex vivo cells. Thus, there was no treatment of cells except processing the samples on ice.

FunGenES: FunGenES_UKOE-5: Transcriptional profiling of CD31(+) cells isolated from murine embryonic stem cells

Project description:This experiment is part of the FunGenES project (FunGenES - Functional Genomics in Embryonic Stem Cells partially funded by the 6th Framework Programme of the European Union, http://www.fungenes.org). The experiment was conducted at University of Cologne, Cologne, Germany. Goal of the experiment is the identification of genes involved in endothelial differentiation. This is of great interest for the understanding of the cellular and molecular mechanisms involved in the development of new blood vessels. Mouse embryonic stem (mES) cells serve as a potential source of endothelial cells for transcriptomic analysis. We isolated endothelial cells from 8-days old embryoid bodies by immuno-magnetic separation using platelet endothelial cell adhesion molecule-1 (also known as CD31) expressed on both early and mature endothelial cells.

The NRF2 inducer CDDO-2P-Im provokes a reduction in amyloid beta levels in Alzheimer’s disease model mice

Project description:Alzheimer’s disease (AD) is the most common etiology of dementia. The transcription factor NF-E2-related factor 2 (NRF2) induces the expression of genes encoding phase II detoxification and antioxidant genes. NRF2 is regulated by Kelch-like ECH-associated protein 1 (KEAP1), and the KEAP1-NRF2 system is the key regulatory system involved in cytoprotection. To examine whether pharmacological induction of NRF2 expression alleviates AD phenotypes in vivo, we employed two AD mouse models, i.e., AppNL-G-F/NL-G-F (AppNLGF) and APPV717I::TAUP301L (APP/TAU) mice. As the synthetic oleanane triterpenoid 1-[2-cyano-3,12-dioxooleana-1,9(11-dien-28-oyl)] (CDDO)-4(-pyridin-2-yl)-imidazole (CDDO-2P-Im) exhibits strong NRF2-inducing activity, in this study, we treated AD model mice with CDDO-2P-Im.
