To establish its effect on treatment outcome in leukaemia, intracellular miR-210 levels were altered by transfecting two different paediatric ALL cell lines (ETV6-RUNX1+ Reh and MLL-AF4+ RS4;11) with an agomiR and antagomiR to miR-210 [55]. This evidence concerns the gene ETV6 and acute lymphoblastic leukemia.
