Importantly, in the identified ceRNA triplets, ANKRD36, FKBP14, PPRC1, and NAB1 were closely related to the prognosis of colon cancer patients (Figure 7B), while PCGF2 and ATP6V1F was tightly linked to the prognosis of rectal cancer patients (Figure 7C), suggesting that lncRNA biomarker may contribute to CRC occurrence and metastasis by regulating prognosis-related gene expression via ceRNA mechanism. This evidence concerns the gene NAB1 and colorectal carcinoma.
