DLK1 and Miyoshi myopathy: Although manipulation of miR-485-5p alone could not mimic the effect on SA-βGalA and the cell cycle of MM-BMMSCs upon cell interaction with MM cells, the results strongly indicate that miR-485-5p and the associated cluster DLK1-DIO3 participate in the regulation of senescence and cell cycle characteristics in MM-BMMSCs.
