Rutaecarpine inhibits glioblastoma migration by activating the aryl hydrocarbon receptor (AhR) signaling pathway

Project description:Glioblastoma is the most frequent and aggressive primary astrocytoma in adults. The high migration ability of the tumor cells is an important reason for the high recurrence rate and poor prognosis of glioblastoma. Recently, emerging evidence has shown that the migration ability of glioblastoma cell was inhibited upon the activation of aryl hydrocarbon receptor (AhR), suggesting potential anti-tumor effects of AhR agonists. Rutaecarpine is a natural compound with potential tumor therapeutic effects which can possibly bind to AhR. However, its effect on the migration of glioblastoma is unclear. Therefore, we aim to explore the effects of rutaecarpine on the migration of human glioblastoma cells U87 and the involvements of the AhR signaling pathway. The results showed that: (i) compared with other structural related alkaloids, like evodiamine and dehydroevodiamine, rutaecarpine was a more potent AhR activator, and has stronger inhibitory effect on the glioblastoma cell migration; (ii) rutaecarpine decreased the migration ability of U87 cells in an AhR-dependent manner; (iii) AhR mediated the expression of a tumor suppressor interleukin 24 (IL24) induced by rutaecarpine, and AhR-IL24 axis was involved in the anti-migratoryeffects of rutaecarpine on the glioblastoma. Besides IL24, other motility related genes were proposed to participate in the migration regulation process of rutaecarpine by RNA-Seq analysis. These data suggest that rutaecarpine is a natural AhR agonist that could inhibit the migration of glioblastomaandbe a potential candidate for developing therapeutic drug against glioblatoma.

Effect of aryl hydrocarbon receptor (Ahr) gene knockout on expression profiles of murine hematopoietic stem cells

Project description:As part of a study of the role of the aryl hydrocarbon receptor (Ahr) in maintenance and senescence of hematopoietic stem cells (HSC), global gene expression profiling was done with HSC isolated from Ahr-knockout and wild-type mice. HSC from young-adult (8 wk old) AhR-KO mice had changes in expression of many genes related to HSC maintenance, consistent with the phenotype observed in aging Ahr-KO mice: decreased survival rate, splenomegaly, increased circulating white blood cells, hematopoietic cell accumulation in tissues, anemia, increased numbers of stem/progenitor and lineage-committed cells in bone marrow, decreased erythroid progenitor cells in bone marrow, and decreased self-renewal capacity of HSC. 7 samples: 3 Ahr knockout, 4 wild-type

Aryl hydrocarbon receptor (AHR)-dependent protection against lung vascular leakage in viral infection

Project description:Disruption of the lung endothelial-epithelial cell barrier during respiratory virus infection causes cell and fluid accumulation in the air spaces and compromises vital gas exchange function. Endothelial cell dysfunction is known to exacerbate tissue damage; however, it is unclear whether the lung endothelium engages in tissue-protective activity during viral infection. Here we show that the environmental sensor aryl hydrocarbon receptor (AHR) is predominantly active in endothelial cells and protects against influenza-induced lung damage. Endothelial-specific AHR deletion caused increased vascular leakage in air spaces and enhanced influenza-induced lung tissue pathology. Global expression profiling revealed limited AHR-dependent regulation of vessels in the steady-state lung. However, following influenza-induced tissue damage and inflammation, AHR engages tissue-protective programmes in endothelia and prevents a dysplastic keratinised and apoptotic signature in the airways of infected lungs.

Effect of bone marrow-specific aryl hydrocarbon receptor (Ahr) gene knockout on expression profiles of hematopoietic stem cells from young and old mice.

Project description:As part of a study of the role of the aryl hydrocarbon receptor (Ahr) in maintenance and senescence of hematopoietic stem cells (HSC), global gene expression profiling was done with HSC isolated from bone marrow restricted conditional Ahr-knockout and AhR floxed mice. HSC from young-adult (8 wk old) cAhR-KO mice had changes in expression of many genes related to HSC maintenance, consistent with the phenotype observed in Ahr-KO mice. Aged cAhR-KO mice (18 months old) also displayed alterations in peripheral white blood cell counts, serial repopulation potential and levels of ROS in bone marrow cells, consistent with previous observations on the role of AhR in the hematopoietic system. 22 samples: 5 young Ahr knockout, 6 old Ahr knockout, 5 young floxed Ahr, 6 old floxed Ahr

The Aryl hydrocarbon receptor and FOS mediated cytotoxicity induced by Acenatobacter baumannii

Project description:Acinetobacter baumannii is a highly pathogenic and multidrug-resistant Gram-negative bacterium that causes severe nosocomial infections. To better understand the mechanism of pathogenesis, we compare the proteomes of uninfected and infected human cells, revealing that transcription factor FOS is the host protein most strongly induced by A. baumannii infection. Pharmacological inhibition of FOS reduces the cytotoxicity of A. baumannii in cell-based models, and similar results are also observed in a mouse infection model. A. baumannii outer membrane vesicles (OMVs) are shown to activate the aryl hydrocarbon receptor (AHR) of host cells by inducing the host enzyme tryptophan-2,3-dioxygenase (TDO), producing the ligand kynurenine, which binds AHR. Following ligand binding, AHR is a direct transcriptional activator of the FOS gene. Our results suggest that bacterial infection interacts with host tryptophan metabolism and the transcription factor FOS.

The aryl hydrocarbon receptor regulates nucleolar activity and protein synthesis in MYC-expressing cells

Project description:MYC enhances protein synthesis by regulating genes involved in ribosome biogenesis and protein translation. Here, we show that MYC-induced protein translation is mediated by the transcription factor aryl hydrocarbon receptor (AHR), which is induced by MYC in colonic cells. AHR promotes protein synthesis by activating the transcription of genes required for ribosome biogenesis and protein translation, including OGFOD1 and NOLC1. Using surface sensing of translation (SUnSET) to measure global protein translation, we found that silencing AHR or its targets diminishes protein synthesis. Therefore, targeting AHR or its downstream pathways could provide a novel approach to limit biomass production in MYC-driven tumors.

Expression data of primary melanocytes from aryl hydrocarbon deficient mice and corresponding wild-type C57BL/6 mice

Project description:[original Title] Comparison of expression data of primary murine melanocytes from aryl hydrocarbon deficient mice and corresponding wild-type C57BL/6 mice Melanin is produced exclusively by melanocytes and melanogenesis is the vital response to protect skin cells against Ultraviolet B (UVB)-induced DNA damage. The aryl hydrocarbon receptor (AhR) is a transcription factor, which may be involved in the physiological tanning response. Normal murine melanocytes express functional AhR. We tested gene expression in WT versus AhR-deficient mice primary murine melanocytes, isolated from the skin and cultivated for several passages. Skin epidermal cells from 2 individual C57BL/6 mice and 2 individual AhR-deficient mice (deletion of exon2, AhRtm1Bra) were grown for 6-8 weeks in selection medium to propagate melanocytes.

Environmental factors transmitted by aryl hydrocarbon receptor influence severity of psoriatic skin inflammation [Affymetrix]

Project description:Environmental stimuli are known to contribute to psoriasis pathogenesis and that of other autoimmune diseases, but the mechanism is unknown. Here we show that the aryl hydrocarbon receptor (AhR), a transcription factor that senses environmental stimuli, modulates pathology in psoriasis. AhR-activating ligands reduced inflammation in the lesional skin of psoriasis patients, whereas AhR antagonists upregulated inflammation. Similarly, AhR signaling via the endogenous FICZ ligand reduced the inflammatory response in the imiquimod-induced model of psoriasis and AhR deficient mice exhibited a substantial exacerbation of the disease, compared to AhR sufficient controls. Non-haematopoietic cells, in particular keratinocytes, were responsible for this hyper-inflammatory response, which involved increased reactivity to IL-1beta and upregulation of AP-1 family members of transcription factors. Thus, our data suggest a critical role for AhR in the regulation of inflammatory responses and open the possibility for novel therapeutic strategies in chronic inflammatory disorders. Total RNA obtained from skin explants taken from AhR heterozygous or knock-out mice treated pericutaneously with imiquimod for 0 and 2d.
