RB1 and colorectal carcinoma: With the development of molecular techniques, new lncRNAs might prove to be vital components in the ceRNA network, which modulates other RNA transcripts.19 Tsang et al20 confirmed that the oncogenic functions of lncRNA H19 in CRC could be attributed to its ceRNA activity of sequestering miR‐675 and downregulating the expression of its target RB.
