demonstrated that silencing Rab27a and Rab27b members of the Rab family could down‐regulate the expression of miR‐23b and miR‐921 in BC cells to reduce cell invasion, indicating that exosome‐mediated tumor‐suppressor miRNA can be coordinated to inhibit the progression of tumor metastasis.82 Here, AGFG1 is linked to neoplasm.
