Project description:To investigate the function SF3B4 during the progression of lung cancer, A549 cells with either SF3B4 siRNA or scramble siRNA were used for RNA-seq.
Project description:To investigate the effect of depletion of RALY on gene expression of A549 cells. We then performed gene expression profiling analysis using data obtained from RNA-seq.
Project description:Alterations in cellular antigen processing and presenting machinery has gained increased interest as a hallmark of cancer-related inflammation. Growing evidence suggest that proteasome composition and immunoproteasome expression can influence antigen processing. By performing immunopeptidomics on A549 lung adenocarcinoma cell line following depletion of proteasome regulator PSME4 we identified alterations in the antigenic landscape resulting from changes in proteasome processing.

Project description:To investigate the difference of miRNA expression between lung cancer cell A549 and its DDP-resistant cell strain A549/DDP, we have employed miRNA microarray expression to discover the difference expression of miRNAs of A549 cells and A549/DDP. We conducted RT-qPCR to examine the expression levels of top differential expressed miRNAs, namely, miR-197-5p, miR-4443, miR-642a-3p, miR-27b-3p and miR-100-5p, confirming low variability between two methods. The A549/DDP was established from A549 in our laboratory, by exposing A549 to gradually increasing DDP concentrations, until the final concentration at 1μg/ml. To avoid the influence of drug to the A549/DDP cells, they were cultured in a drug-free medium for at least two weeks before gene expression analysis. miRNA expression of A549 and A549/DDP was then analzyed.
Project description:TGFb and/or crizotinib were treated on A549 cell line to understand molecular mechanisms of action of crizotinib in TGF signaling pathway in lung cancer through gene expression profile data.
Project description:To investigate the cytotoxic effect of AKR1B1 depletion, we induced stable AKR1B1 knockdown via shRNA under different growth conditions (glucose vs fructose) We then performed gene expression profiling analysis using data obtained from RNA-seq of control (non-targeting shRNA) or shAKR1B1 A549 cells 5 days after shRNA delivery.
