circRNA expression data from human colorectal cancer tissues and the correponding non-cancerous tissues

To identifythe the functional roles of circRNAs in human colorectal cancer, we analysed the differenial expression of circRNAs in 5 colorectal cancer tissues and the corresponding non-cancerous tissues. We used microarrays to detail the global programme of circRNA expression in human colorectal cancer tissues and correponding non-cancerous tissues. Total RNA from 5 pairs human colorectal cancer tissues and correponding non-cancerous tissues were isolated and digested with Rnase R. The enriched circular RNAs were amplified and transcribed into fluorescent cRNA. The labeled cRNAs were hybridized onto the Arraystar Human circRNA Array (8x15K, Arraystar)
