Project description:We performed RNA-seq analysis using different bladder cancer cell lines (5637 and T24) after protodioscin treatment. We reported that protodioscin regulates MAPK pathway-associated genes in 5637 and T24 cells. Protodioscin induces apoptosis and suppresses cell cycle progression, cell migration and invasion in 5637 and T24 cells.
Project description:To identification of key drivers involved in the development of muscle invasive bladder cancer, which displays poor prognosis, we isolated one subpopulation of human 5637 bladder cancer cells with highly invasiveness and the other subpopulation of 5637 cells with low invasiveness by Transwell method. Through proteomic analysis, differentially expressed proteins were displayed.
Project description:In this study, we aimed to explore RNAs profiling regulated by LNPPS in bladder cancer. RNA-seq analysis of three pairs of LNPPS-overexpressing 5637 cells and control cells was completed in this project. A total of 17.6Gb raw data was obtained. In concluion, our data showed that the overexpression of LNPPS caused the significantly upregulation of 82 mRNAs, and the downregulation of 102 mRNAs (|Log2FC|>1.5, p<0.05). Further studies will focus on the potential regulatory mechanisms of these significantly differently expressed mRNAs in the LNPPS-mediated development of bladder cancer.

Project description:We have sequenced miRNA libraries from human embryonic, neural and foetal mesenchymal stem cells. We report that the majority of miRNA genes encode mature isomers that vary in size by one or more bases at the 3’ and/or 5’ end of the miRNA. Northern blotting for individual miRNAs showed that the proportions of isomiRs expressed by a single miRNA gene often differ between cell and tissue types. IsomiRs were readily co-immunoprecipitated with Argonaute proteins in vivo and were active in luciferase assays, indicating that they are functional. Bioinformatics analysis predicts substantial differences in targeting between miRNAs with minor 5’ differences and in support of this we report that a 5’ isomiR-9-1 gained the ability to inhibit the expression of DNMT3B and NCAM2 but lost the ability to inhibit CDH1 in vitro. This result was confirmed by the use of isomiR-specific sponges. Our analysis of the miRGator database indicates that a small percentage of human miRNA genes express isomiRs as the dominant transcript in certain cell types and analysis of miRBase shows that 5’ isomiRs have replaced canonical miRNAs many times during evolution. This strongly indicates that isomiRs are of functional importance and have contributed to the evolution of miRNA genes Sequence library of miRNAs from a single sample of human foetal mesenchymal stem cells. Results tested and confirmed by northern blotting. Please note that only raw data files are available for the embryonic and neual samples and thus, directly submitted to SRA (SRX547311, SRX548700, respectively under SRP042115/PRJNA247767)
Project description:Mitomycin C (MMC) is the gold standard treatment for non-muscle invasive bladder cancer (NMIBC). We aimed to evaluate in bladder cancer cell lines (T24, 5637, TCC-SUP and CLS-439) the transcriptomic response to MMC treatment. We used Gene Set Enrichment Analysis (GSEA) to identify biological processes and pathways modulated by MMC treatment.
