CTNNB1 and hepatocellular carcinoma: LEAWBIH (lncRNA epigenetically activating Wnt/β-catenin signaling in HCC) contains m6A marks that allow its binding by the m6A reader YTHDC1, followed by interaction with and recruitment of H3K9me2 demethylase KDM3B to the CTNNB1 promoter, leading to CTNNB1 transcription, thus activating Wnt/β-catenin signaling [134].
