Crosstalk Mechanism histone modification directly impacts m6A modification through modulating the level of m6A regulator
Crosstalk Summary First, we found that ocular melanoma cells presented vulnerability towards HDACis. HDACis triggered the elevation of m6A RNA modification in ocular melanoma. Further studies revealed that METTL14 served as a downstream candidate for HDACis. METTL14 was silenced by the hypo-histone acetylation status, whereas HDACi restored the normal histone acetylation (H3K27ac/Histone H3 lysine 9 acetylation (H3K9ac)) level of METTL14, thereby inducing its expression. Subsequently, METTL14 served as a tumor suppressor by promoting the expression of Protocadherin Fat 4 (FAT4), a tumor suppressor, in a m6A-YTHDF1-dependent manner. Taken together, we found that HDACi restored the histone acetylation level of METTL14 and subsequently elicited METTL14-mediated m6A modification in tumorigenesis.
