Effect of persistent ER stress on gene expression of pancreatic ductal adenocarcinoma cell AsPC1

To investigate the changes of gene expression in pancreatic ductal adenocarcinoma cells under persistent endoplasmic reticulum stress, we treated AsPC-1 cells with 30 nM thapsigargin (Tg) for more than 14 days (designated as AsPC-1-Tg). To investigate whether the effects of persistent ER stress on gene expression is permanent or reversible, we cultured AsPC-1-Tg cells in a medium without Tg (designated as AsPC-1-Tg-Re) for 4 days. In this study, we then performed gene expression profiling analysis using data obtained from high-throughput RNA-seq (include mRNA, lncRNA, circRNA and miRNA) of AsPC-1 (WT), AsPC-1-Tg (TG) and AsPC-1-Tg-Re (RE) cells. Three biological replicates of each sample were used for RNA-seq. Comparative gene expression profiling analysis of RNA-seq data for AsPC-1 (WT), AsPC-1-Tg (TG) and AsPC-1-Tg-Re (RE) cells.
