RNA-seq of miR-146a-5p overexpressing T24 human bladder cancer cells

Project description:We established stable miR-146a-5p overexpression T24 cells, then performed transcriptome profiling of miR-146a-5p overexpressing cells compared to control T24 cells to detect the molecular mechanisms of the miR-146a-5p’s effect on bladder cancer cells.

Therapeutic inhibition of METTL3/miR-146a-5p-guided NOTCH pathway suppresses bladder cancer progression

Project description:Bladder cancer characterized by RNA methylation abnormalities and NOTCH pathway dysregulation exhibits high recurrence that remains the major obstacle for bladder cancer treatment. Targeting methyltransferase-like 3 (METTL3) and NOTCH signal is a potential strategy to block bladder cancer progression. However, the underlying mechanisms by which METTL3-manipulated NOTCH signal and its effect on bladder cancer tumorigenesis remain to be clarified. Here we showed that METTL3-guided m6A modification methylated pri-miR-146 at the flaking sequence, which was responsible for the pri-miR-146 maturation. Furthermore, NUMB/NOTCH2 axis was identified as the functional downstream target signal that mediated the pro-survival role of miR-146a-5p in bladder cancer cells. Therapeutically, the polypeptide melittin was demonstrated to induce apoptosis of bladder cancer cells in a METTL3-dependent manner. Importantly, METTL3 and miR-146a-5p were positively correlated with recurrence and poor prognosis of bladder cancer patient. Our studies indicate that METTL3/miR-146a-5p/NUMB/NOTCH2 axis could be a potential therapeutic target for recurrent bladder cancer treatment and METTL3 acts as a fate determinant that controls sensitivity of bladder cancer cells to melittin treatment.

miR-146a-5p expression effect on human mesenchymal stem cell

Project description:Analysis of human mesenchymal stem cells (MSC) from bone marrow and the Wharton's jelly of the umbilical cord after manupulating miR-146a-5p expression. miR-146a-5p is involved in controlling the proliferation and migration of MSCs. Results provide miR-146a-5p-regulating genes in MSCs. In this study, BM-MSCs transduced with miR-146a-5p expression vector or pCDH-CMV-MCS-EF1-copGFP vector only, as well as two WJ-MSCs transfected with short interfering RNAs targeting miR-146a or a GFP control.

miR-146a-5p contributes to inflammation-mediated β cell mitochondrial dysfunction and apoptosis

Project description:MicroRNAs (miRNAs) are small non-coding RNAs that function as modulators of gene expression. We previously showed that miR-146a-5p is upregulated in pancreatic islets treated with pro-inflammatory cytokines and in pancreatic sections from organ donors with type 1 diabetes (T1D). Other studies have associated overexpression of miR-146a-5p with β cell apoptosis and impaired insulin secretion; however, the molecular mechanisms mediating these effects remain elusive. To investigate the role of miR-146a-5p in β cell function, we developed stable MIN6 cell lines transduced with lentiviral vectors to either overexpress or inhibit the expression of miR-146a-5p. Monoclonal cell populations were treated with pro-inflammatory cytokines (IL1β, IFNg, and TNFα) to model T1D in vitro. We found that overexpression of miR-146a-5p increased the cell death of MIN6 cells under inflammatory stress, whereas inhibition of miR-146a-5p reversed these effects. Additionally, inhibition of miR-146a-5p increased mitochondrial DNA copy number, respiration rate, and ATP production, suggesting that miR-146a-5p inhibition improves mitochondrial function. In support of this finding, we also observed that miR-146a-5p is enriched in the mitochondria of MIN6 cells treated with cytokines. Consistently, bioinformatic analysis of RNA sequencing data using MIN6 stable cells showed enrichment of pathways related to insulin secretion, apoptosis, and mitochondrial function when the expression levels of miR-146a-5p were altered. Overall, the findings from our study show for the first time that miR-146a-5p upregulation during inflammatory stress may promote β cell dysfunction and death by suppressing mitochondrial function.

Expression data for T24 bladder cancer cell line - scrambled, SOX4-KD and SOX4 overexpression

Project description:We knocked down SOX4 in T24 cell and created 3 cell lines: T24-scrambled, T24-SOX4-knockdown and T24-SOX4-rescue and compared gene expression changes SOX4 is a developmental transcription factor that is overexpressed in as many as 23% of bladder cancer patients, but the role of SOX4 in bladder cancer tumorigenesis is not well understood. Given SOX4’s many roles in embryonic development and context-dependent regulation of gene expression, we sought to understand SOX4’s contribution to bladder cancer and to elucidate SOX4 regulated genes that might contribute to tumorigenesis. We employed a CRISPR interference (CRISPRi) method to transcriptionally repress SOX4 expression in T24 bladder cancer cell lines, rescued these cell lines with lentivirally expressed SOX4, and performed whole genome expression profiling. SOX4 knockdown cells exhibited decreased invasive capabilities but no changes in migration or proliferation, while rescue with SOX4 lentiviral vector restored the invasive phenotype. Gene expression profiling revealed 173 high confidence SOX4 regulated genes
