METTL3 and IGF2BP2 coordinately regulate FOSL1 mRNA via m6A modification, suppressing trophoblast invasion and contributing to fetal growth restriction.

ABSTRACT: Fetal growth restriction (FGR) increases the risk of short-term and long-term complications. Widespread N6-methyladenosine (m6A) modifications on mRNAs have been found to be involved in various biological processes. However, the role of m6A modification in the pathogenesis of FGR remains elusive. Here, we report that elevated levels of METTL3 and m6A modification were detected in FGR placentae. Functionally, cell migration, invasion, and proliferation abilities were suppressed after METTL3 overexpression in HTR8/SVneo cells. Subsequently, methylated RNA immunoprecipitation sequencing (MeRIP-seq) and RNA sequencing (RNA-seq) of METTL3-knockdown HTR8/SVneo cells were utilized together to identify FOSL1 as the downstream target genes of METTL3. Furthermore, we illustrated that METTL3-mediated
