CEBPB and colorectal carcinoma: The lncRNA LncLy6C, induced by the microbiota metabolite butyrate, binds to the transcription factor CCAAT/enhancer binding protein β (C/EBPβ) and several lysine methyltransferases of H3K4me3, specifically encouraging the enrichment of C/EBPβ and H3K4me3 marks on the promoter region of Nr4A1, nuclear subfamily 4 (NR4A) receptor, which is overexpressed in CRC and plays a central role in controlling cell proliferation, apoptosis, and metastasis [37,75].
