To distinguish the specific roles of the miR-200c and miR-141 families, we infected RT2_DKO tumor-derived cells with adenoviruses harboring either the endogenous Mir141~200c locus (ad-141~200c) or the Mir141 or Mir200c genes alone (ad-141 and ad-200c, respectively) (Supplementary Figure 5a, b). Here, MIR141 is linked to neoplasm.
