Core Tip

Core tip: We acquired high-throughput data from The Cancer Genome Atlas database and constructed the competing endogenous RNA (ceRNA) networks of colorectal cancer by bioinformatics analysis, which included 81 differentially expressed (DE)lncRNAs, 20 DEmiRNAs, and 54 DEmRNAs. Furthermore, 3 lncRNAs, 3 miRNAs, and 2 mRNAs were found associated with overall survival. Our study revealed that ceRNA networks are important in colorectal cancer and the prognosis-related genes worth exploring further.
