OLFM4 and colorectal carcinoma: In addition, OLFM4 was significantly increased in the CRC tissues (fold change = 6.918, P-value = 0.0017, Fig. 6e), which was consistent with the data obtained from the SE-lncRNA microarray (fold change = 34.033, P-value = 0.0036) and RNA-seq (fold change = 2.287, P-value = 0.0034).
