These three miRs were chosen as our top candidate regulators of PIAS3 expression along with miR‐18a, which has been reported to be upregulated in both MM cell lines and MM tumor samples compared to normal tissue (Amatya et al., 2016; Balatti et al., 2011; Ramirez‐Salazar et al., 2014). This evidence concerns the gene PIAS3 and Miyoshi myopathy.
