METTL3 and neoplasm: Consistently, at 5 weeks post‐HTVI, the livers of the Mettl3 cKO group exhibited more notable tumor development (with increased surface tumor number and increased maximum surface tumor diameter) and significantly increased liver‐to‐body weight ratio (Fig. 2G–J), as well as dramatic increases in AST, ALT, TBIL, and DBIL levels (Fig. 2K).
