HOXA10 overexpression rescues METTL3-impaired embryo attachment in vitro. a The mRNA levels of METTL3, HOXA10, ITGB3 and EMX2 in the METTL3-overexpressing Ishikawa cells with or without HOXA10 overexpression were analyzed by qRT-PCR. b The protein levels of METTL3, HOXA10, ITGB3 and EMX2 in the METTL3-overexpressing Ishikawa cells with or without HOXA10 overexpression were analyzed by Western blotting. c The levels of m⁶A RNA methylation in the METTL3-overexpressing Ishikawa cells with or without HOXA10 overexpression were evaluated by the m⁶A RNA Methylation Assay Kit. d The levels of m⁶A in the METTL3-overexpressing Ishikawa cells with or without HOXA10 overexpression were evaluated by dot blotting assay. e A vitro model of a confluent monolayer of Ishikawa cells co-cultured with BeWo spheroids was used to evaluate the embryo attachment. Bar 100 μm. The data are the average of three independent experiments (n=3). *P<0.05, **P<0.01, **P<0.001 versus the indicated group
