Crosstalk Relationship Histone modification  →  m6A Enhancement
Crosstalk Mechanism histone modification directly impacts m6A modification through modulating the level of m6A regulator
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. METTL3 modulates miR-193b mature process in an m6A-dependent manner. Reintroduction of hsa-miR-193b profoundly inhibits tumorigenesis of cervical cancer cells both in vivo and in vitro through CCND1 targeting.

In-vivo Model Mice were divided into two groups (n = 4/group) randomly. 3× 106 cells suspended in 200 uL PBS were administered via subcutaneous injection over the right flank region of nude mice. After the development of palpable tumors (average volume, 50 mm3), intratumoral injection of synthetic miR-193b, or negative control complexed with siPORT Amine transfection reagent (Ambion, USA) was given 6 times at a 4-day interval.
