Project description:Transcriptional profiling of human lung cancer cell lines A549 comparing control cells transfected with an empty lentiviral expression vector pEZ-Lv201 and A549 cells transfected with a pEZ-Lv201-FENDRR. The latter forms a FENDRR stably over-expressed cell lines. Goal was to to assess the alteration of gene expression profiles caused by FENDRR upregulation.
Project description:The study evaluated the differential gene expression in CBX5 knockdown cells compared to control shRNA expressed HCC827 cells. Briefly, human lung cancer HCC827 cells stably expressing either CBX5 shRNAs or control shRNA were analysed for gene expression.
Project description:Briefly, Human lung cancer HCC827 cells were stably expressing either CBX5 shRNAs or control shRNA were analysed for open chromatin structures using ATAC seq Analysis.
Project description:To investigate the role of TGF-M-NM-21-regulated miRNAs in the progression of colorectal cancer,we performed comprehensive miRMA microarray analysis on RNA derived from typical human colorectal cancer cell lines and TGF-M-NM-21 knock-down human colorectal cancer cell lines. We identified a novel set of TGF-M-NM-21-related miRNAs. Total RNA was isolated from TGF-M-NM-21-knock down colorecatl cancer cell lines and controls.Three-condition experiment: shRNA-TGF-M-NM-21/Lovo cells vs. shRNA-Control/Lovo cells, shRNA-TGF-M-NM-21/SW620 cells vs. shRNA-Control/ SW620 cells, and shRNA-TGF-M-NM-21/HT29 cells vs. shRNA-Control/HT29 cells. Biological replicates: 1 Lovo cells stably transfected with shRNA-TGF-M-NM-21- pSUPER gfp-neo, 1SW620 cells stably transfected with shRNA-TGF-M-NM-21- pSUPER gfp-neo, 1HT29 cells stably transfected with shRNA-TGF-M-NM-21- pSUPER gfp-neo, 1Love cells stably transfected with shRNA-Control- pSUPER gfp-neo, 1SW620 cells stably transfected with shRNA-Control- pSUPER gfp-neo, and 1HT29 cells stably transfected with shRNA-Control- pSUPER gfp-neo, independently grown and harvested. One replicate per array.
Project description:Snail is a zinc-finger transcription factor best known for its ability to down-regulate E-cadherin. Its established significance in embryology and organogenesis has been expanded to include a role in the tumor progression of a number of human cancers. In addition to E-cadherin, it has more recently been associated with the down-regulation and up-regulation of a number of other genes that affect important malignant phenotypes. After establishing the presence of up-regulated Snail in human non-small cell lung cancer specimens, we used microarrays to detail the global programme of gene expression in non-small cell lung cancer cell lines stably transduced to over-express Snail as compared to vector control cell lines. Non-small cell lung cancer cell lines (H441, H292, H1437) were stably transduced with a retroviral vector to over-express Snail. Elevated Snail and a corresponding down-regulation of E-cadherin was verified in the Snail over-expressing cell lines as compared to vector control cell lines by Western analysis. RNA extraction was performed and samples submitted to the UCLA Clinical Microarray Core for hybridization to Affymetrix arrays.
Project description:We sequenced mRNA from 6 human cell lines stably over-expressed specific gene or empty vector, and searched for differently expressed genes after gene over-expression as compared to empty vector. mRNA levels were compared as following pairs: U2OS+hTERT vs U2OS+vector; U2OS+hTERTmut vs U2OS+vector; VA-13+hTERT vs VA-13+vector; VA-13+hTERTmut vs VA-13+vector.
