Mechanistically, IGF2BP3 recognized m6A-modified EMP1 mRNAs to prolong stability of them, which inhibits the hindrance of SMAD7 to SMAD3/4 phosphorylation by promoting the binding of VASP and SMAD7. Finally, a tight correlation of the local invasion/IGF2BP3/EMP1 and infiltration of immune cells in the tumor microenvironment is evidenced in clinical PDAC. Here, VASP is linked to neoplasm.
