Methods: mRNA profiles of cell lines were generated using Illumina PE150, then GSEA was used for analyzing the association between SYK knockdown and the mesenchymal or epithelial signature. Results: The result showed epithelial signatures were up-regulated, while mesenchymal signatures were down-regulated upon SYK knockdown in RNA-seq data. Conclusions: Our study systematically examined the cellular transcriptomes affected by SYK knockdown, with biologic replicates, generated by RNA-seq technology. SYK knockdown results in the transcriptional change of multiple epithelial and mesenchymal markers, leading to mesenchymal state switching. Overall design: mRNA profiles of SYK stable knockdown and corresponding negative control generated from 3 cancer cell lines, individually.
