Moreover, we found several important shared mRNAs between ceRNA networks of COAD and READ (CRC, cancer cluster 3:CC-3) (Table 2), which included APC, EDIL3, FGFR2, HOMER1, MIER3, PI15, RBM28, RRS1, SCML1, SGPP1, TOMM34, TRAF5, WNT5A, and ZNF655. For other cancer clusters, other important shared mRNAs as shown in Table 2 were identified. Here, RBM28 is linked to colorectal carcinoma.
