Subsequently, we found the up-regulation of SOX13 mRNA and protein levels in MM serums (Fig. 4d, e) and cells (Fig. 4f, g) in comparison to normal serums and cells aThere was a negative association (r = − 0.6404, P < 0.001) between miR-1271-5p and SOX13 in MM serum samples (Fig. 4h). The gene discussed is SOX13; the disease is Miyoshi myopathy.
