Expression data from U87-2M1 glioma cells transduced with baculoviral control decoy vector or baculoviral miR-10b decoy vector

ABSTRACT: MicroRNA-10b may target numerous genes in gliomagenesis. The target genes of miR-10b may differ according to the cellular context. We used microarray analyses to determine the phenotypic effects and gene targets of miR-10b by silencing miR-10b in invasive U87-2M1 glioma cells.

miRNA sequencing profile of colonic mucosa in global mir-10b KO and WT mice

Project description:Background/ Aim: Diabetes has substantive co-occurrence with disorders of gut-brain interactions (DGBIs). The pathophysiological and molecular mechanisms linking diabetes and DGBIs are unclear. miRNAs are key regulators of diabetes and gut dysmotility. We investigated whether impaired gut barrier function regulated by a key miRNA, miR-10b-5p, links diabetes and gut dysmotility. Methods: We created a new mouse line using the Mb3Cas12a/Mb3Cpf1 endonuclease to knock out mir-10b globally. Loss of function studies were conducted to characterize diabetes, gut dysmotility, and gut barrier dysfunction phenotypes in these mice. Gain of function studies were conducted by injecting these mice with a miR-10b-5p mimic. Further, we performed miRNA-sequencing analysis from colonic mucosa from mir-10b KO, WT, and miR-10b-5p mimic injected mice to confirm 1) deficiency of miR-10b-5p in KO mice, and 2) restoration of miR-10b-5p expression after the mimic injection. Results: Congenital loss of mir-10b in mice led to the development of hyperglycemia, gut dysmotility, and gut barrier dysfunction. We found increased gut permeability and reduced expression of the tight junction protein Zonula occludens-1 (ZO-1), in the colon of mir-10b KO mice. We further confirmed that patients with diabetes or IBS-C, a known DGBI that is linked to leaky gut, had significantly reduced miR-10b-5p expression. Injection of a miR-10b-5p mimic in mir-10b KO mice rescued these molecular alterations and phenotypes. Conclusion: Our study uncovered a potential pathophysiologic mechanism of gut barrier dysfunction that links both the diabetes and gut dysmotility phenotypes in mice lacking miR-10b-5p. Treatment with a miR-10b-5p mimic reversed the leaky gut, diabetic, and gut dysmotility phenotypes, highlighting the translational potential of miR-10b-5p mimic.

Discovery of Gene Expression Signature in the Overexpression of miR-145 in U87 glioma cell.

Project description:We have employed whole RNA microarray expression profiling as a discovery platform to identify genes regulated by overexpression of miR-145 in U87 glioma cell. Lentivirus containing miR-145 coding sequence was infected to U87 cell to make U87 overexpressing miR-145. We did genome microarray between U87 and U87 overexpressing miR-145.

High-throughput microRNA profile in adult and pediatric primary glioblastomas: the role of miR-10b-5p and miR-630 in the tumor aggressiveness

Project description:Glioblastoma (GBM) is the most common primary malignant neoplasm of the central nervous system and, despite the standard therapy; the patients’ prognoses remain dismal. The miRNA expression profiles have been associated with patient prognosis, suggesting that they may be helpful for tumor diagnosis and classification as well as predictive of tumor response to treatment. We described the microRNA expression profile of 29 primary GBM samples (9 pediatric GBMs) and 11 non-neoplastic white matter samples as controls (WM) by microarray analysis and we performed functional in vitro assays on these 2 most differentially expressed miRNAs. Hierarchical clustering analysis showed 3 distinct miRNA profiles, two of them in the GBM samples and a group consisting only of cerebral white matter. When adult and pediatric GBMs were compared to WM, 37 human miRNAs were found to be differentially expressed, with miR-10b-5p being the most overexpressed and miR-630 the most underexpressed. The overexpression of miR-630 was associated with reduced cell proliferation and invasion in the U87 GBM cell line, whereas the inhibition of miR-10b-5p reduced cell proliferation and colony formation in the U251 GBM cell line, suggesting that these miRNAs may act as tumor-suppressive and oncogenic miRNAs, respectively. The present study highlights the distinct epigenetic profiling of adult and pediatric GBMs and underscores the biological importance of mir-10b-5p and miR-630 for the pathobiology of these lethal tumors.

Promoter and enhancer RNAs regulate chromatin reorganization and activation of miR-10b/HOXD locus and neoplastic transformation in glioma [ChIP-seq]

Project description:Using a combination of chromatin capture techniques, ChIP-Seq, single-molecule in situ RNA analysis, and computational analysis of large-scale TCGA datasets, we identified an epigenetic mechanism underlying common activation of HOXD/miR-10b locus in otherwise highly heterogenous glioma brain tumors. We demonstrate for the first time that two remote lncRNAs, one associated with a genomic promoter and another with a newly identified enhancer, cooperatively shape the 3D chromatin structure and looping, leading to the activation of a large gene cluster (12 genes, 110 KB) that includes the regulatory miRNA essential for glioma survival. This work describes a new mechanism contributing to neoplastic transformation in gliomagenesis, and identifies new avenues for therapeutic interventions based on the promoter and enhancer associated regulatory transcripts.
