Project description:IL-17B/IL-17RB signaling cascade contributes to self-renewal and tumorigenesis of cancer stem cells by regulating Beclin-1 ubiquitination
| PRJNA688691 | ENA
Project description:Cancer stem cells (CSCs) are characterized by robust self-renewal and tumorigenesis and are responsible for metastasis, drug resistance, and angiogenesis. However, the molecular mechanisms for the regulation of CSC homeostasis are incompletely understood. This study demonstrated that the interleukin-17 (IL-17)B/IL-17RB signaling cascade promotes the self-renewal and tumorigenesis of CSCs by inducing Beclin-1 ubiquitination. We found that IL-17RB expression was significantly upregulated in spheroid cells and Lgr5-positive cells from the same tumor tissues of patients with gastric cancer (GC), which was closely correlated with the degree of cancer cell differentiation. Recombinant IL-17B (rIL-17B) promoted the sphere-formation ability of CSCs in vitro and enhanced tumor growth and metastasis in vivo. Interestingly, IL-17B induced autophagosome formation and cleavage-mediated transformation of LC3 in CSCs and 293T cells. Furthermore, inhibition of autophagy activation by ATG7 knockdown reversed rIL-17B-induced self-renewal of GC cells. In addition, we showed that IL-17B also promoted K63-mediated ubiquitination of Beclin-1 by mediating the binding of tumor necrosis factor receptor-associated factor 6 to Beclin-1. Silencing IL-17RB expression abrogated the effects of IL-17B on Beclin-1 ubiquitination and autophagy activation in GC cells. Finally, we showed that IL-17B level in the serum of GC patients was positively correlated with IL-17RB expression in GC tissues, and IL-17B could induce IL-17RB expression in GC cells. Overall, the results elucidate the novel functions of IL-17B for CSCs and suggest that the intervention of the IL-17B/IL-17RB signaling pathway may provide new therapeutic targets for the treatment of cancer.

Project description:Purpose: Explore IL-17B target genes expression via next-generation sequencing (NGS) in mouse lung tissues. Methods: Overexpress IL-17B in mouse lung tissues via intranasal injection of adenovirus encoding IL-17B (Adv-IL-17B) and empty virus (Adv-EV). Three days after infection lung tisses were removed for RNA collection. Five samples per group were mixed to one sample and used for next RNA purification. RNA samples were then used for high-throughput sequencing according to standard operation based on RNA Hiseq 4000. Results: Using an optimized data analysis workflow, we mapped about 13 million sequence reads per sample to the mouse genome (build mm10) and identified 269 upregulated and 99 downregulated genes in lung after IL-17B overexpression. RNA-seq data had a linear relationship with qRT–PCR for more than four orders of magnitude and a goodness of fit (R2) of 0.8798. Altered expression of 20 genes was confirmed with qRT–PCR, demonstrating the high degree of sensitivity of the RNA-seq method. Hierarchical clustering of differentially expressed genes uncovered several as yet uncharacterized genes that may contribute to lung inflammation and infection. Data analysis with BWA and TopHat workflows revealed a significant overlap yet provided complementary insights in transcriptome profiling. Conclusions: Our study represents the first detailed analysis of IL-17B induced downstream genes with biologic replicates, generated by RNA-seq technology. The optimized data analysis workflows reported here should provide a framework for comparative investigations of expression profiles. We conclude that RNA-seq based downstream genes characterization would expedite genetic network analyses and permit the dissection of complex biologic functions.

Project description:Cerebral small vessel disease and brain white matter injury are worsened by cardiovascular risk factors including obesity. Molecular pathways in cerebral endothelial cells activated by chronic cerebrovascular risk factors alter cell-cell signaling, blocking endogenous and post-ischemic white matter repair. Using cell-specific translating ribosome affinity purification(RiboTag) in white matter endothelia and oligodendrocyte progenitor cells (OPCs), we identify a coordinated interleukin-chemokine signaling cascade within the oligovascular niche of subcortical white matter that is triggered by diet-induced obesity (DIO).DIO induces IL-17B signaling that acts on the cerebral endothelia through IL-17Rb to increase both circulating and local endothelial expression of CXCL5. In white matter endothelia, CXCL5 promotes the association of OPCs with the vasculature and triggers OPC gene expression programs regulating cell migration through chemokine signaling. Targeted blockade of IL-17B reduced vessel-associated OPCs by reducing endothelial CXCL5 expression. In multiple human cohorts, blood levels of CXCL5 function as a diagnostic and prognostic biomarker of vascular cognitive impairment.

Project description:We report the high-throughput profiling of murine intestinal type 2 innate lymphoid cells (ILC2) transcriptome. By obtaining over 8.7 million bases of sequence, we generated genome-wide expression maps of mouse ILC2 without the presense of known activation signals(IL-25, IL-33 receptor) and new non-redundant signal (leukotriene). We find that homeostatic signaling minimally contributes to intestinal ILC2 activation statu. 500 ILC2s were sorted as CD45+Lineage-IL-17RB+

Project description:Background: Chronic rhinosinusitis with nasal polyposis (CRSwNP) in western countries is characterized by eosinophilia, IgE production and Th2 cytokine expression. Type 2 innate lymphoid cells (ILC2) from polyps produce IL-5 and IL-13 in response to IL-25 and IL-33 although the relevance of this axis to local mucosal T cell responses is unknown. Objective: To investigate the role of the IL-25/IL-33 axis in local mucosal T cell responses in CRSwNP. Methods: Polyp tissue and blood were obtained from patients undergoing nasal polypectomy. Control nasal biopsies and blood were obtained from healthy volunteers. Tissue was cultured in a short-term explant model. T cell surface phenotype/intracellular cytokines were assessed by flow cytometry. TCR Vβ analysis was performed with the immunoSEQ assay. Microarrays were performed for gene expression analysis. Results: Using nasal polyp tissue, numerous IL-25 receptor (IL-17RB) positive polarized Th2 cells were identified which were absent in the healthy nasal mucosa and periphery. IL-17RB+CD4+ polyp Th2 cells co-expressed ST2 (IL-33 receptor) and responded to IL-25 and IL-33 with enhanced IL-5 and IL-13 production. Within IL-17RB+CD4+ T cells several identical TCR Vβ CDR3 sequences were identified in different subjects suggesting clonal expansion driven by a common antigen. Abundant IL-17 producing T cells were observed in healthy nasal mucosal and polyp populations with Th17-related genes the most overexpressed compared to peripheral blood T cells. Conclusion: IL-25 and IL-33 may interact locally with IL-17RB+ST2+ polyp T cells to augment Th2 responses in CRSwNP. A local Th17 response may be the default signature in healthy nasal mucosal immune homeostasis. Three biological replicates. T-helper cells were isolated nasal polyps by explant culture from patients with chronic rhinosinusitis. Cells were then sorted based upon expression of IL17RB by flow cytometric sorting. Resting and activated IL-17RB+ve cells were compared with resting and activated IL-17RB-ve cells.
