ELFN1 and colorectal carcinoma: Relatively high mRNA levels of ELFN1-AS1 were detected in CRC tissues and cell lines (Fig. 7a, b) and verified by public datasets (Supplementary Fig. S7a), and ROC curve analysis indicated that ELFN1-AS1 combined with MEIS1 was superior to MEIS1 alone for diagnosing CRC (Supplementary Fig. S7b, c).
