Crosstalk Summary The transcription factor ETS1 recruited p300 and WDR5 which separately mediated Histone H3 lysine 27 acetylation (H3K27ac) and H3K4me3 histone modification in the promoter of METTL3 and induced METTL3 transcription activation. Furthermore, we identified TXNDC5 as a target of METTL3-mediated m6A modification through MeRIP-seq, and revealed that METTL3-mediated TXNDC5 expression relied on the m6A reader-dependent manner. DARS-AS1 was validated to facilitate DARS translation via recruiting METTL3 and METTL14, which bound with DARS mRNA Aspartate--tRNA ligase, cytoplasmic (DARS) mRNA 5' untranslated region (5'UTR) and promoting its translation. The present study demonstrated that the 'HIF1-Alpha/DARS-AS1/DARS/ATG5/ATG3' pathway regulated the hypoxia-induced cytoprotective autophagy of cervical cancer(CC) and is a promising target of therapeutic strategies for patients afflicted with CC.
