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.

Project description:RNA profiling by RNA-Seq analyses showed that in comparison with the control Dotap-treated cells, miR-574-5p transfection for 24 h resulted in significant up-regulation of 277 genes and down-regulation of 80 genes by at least 2-fold in the miR-574-5p-transfected splenocytes. Gene ontology and pathway enrichment analyses showed that the 277 significantly up-regulated genes in miR-574-5p-transfected cells were highly enriched and clustered in pathways associated with interferon and cytokine signaling, antiviral mechanisms, translesion synthesis and autoimmunity .

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.

Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are using mRNA and microRNA sequencing analysis to evaluate the effects of EBV-encoded microRNA BART2-5p mimics on the mRNA and microRNA profiles of human nasopharyngeal carcinoma cell line 6-10B. Methods: 6-10B cells were transfected with either EBV microRNA BART2-5p mimics or negative control (NC) mimics for 48 hours. Cellular RNA was then sequenced at the mRNA and microRNA levels using illumina high-throughput sequencing service (Oebiotech, Shanghai, China). Data were extracted and normalized according to the manufacturer's standard protocol. Results: Log-fold changes of up- or down-regulated mRNAs and microRNAs between the control and experiment group were selected with a significance threshold of p<0.05. Conclusions: Our study describes the mRNA and microRNA alterations induced by EBV-miRNA-BART2-5p in 6-10B cells

Project description:miR-125b-5p is a well known miRNA already describded in several forms of cancer. miR-125b-5p is expressed in adipose tissue, adipocytes as well as their precursor cells. We aim to invest the role of miR-125b-5p in white adipocytes conversion into brite adipocytes. To get an idea about putative targets of miR-125b-5p in adipocyte conversion, we transfected miR-125b-5p mimic in human Multipotent Adipose-Derived Stem (hMADS) cells, differenciated in white adipocytes. Gene expression profiling is performed 48h after hMADSC transfection. Two-condition experiment, hMADS cells at day 16 after conversion of white adipocytes into brite adipocytes, comparison of cells transfected with a mimic miR-125b-5p to cells transfected with a negative controle. Biological replicates: 4, indepently grown and harvested. On each array, one biological replicate of mimic miR-125b-5p transfected cells was directly compared to one biological replicate of mimic negative control transfected cells (serving as reference sample). All hybridizations were repeated with reversed dye assignment (dye-swap) as technical replicates.
