ATG14 and Miyoshi myopathy: As shown in Fig. 7A–D, circ_0058058 knockdown led to a significant reduction of ATG14 expression both at mRNA and protein levels, which were rescued by the inhibition of miR-338-3p in H929 and MM.1S cells, suggesting the circ_0058058/miR-338-3p/ATG14 feedback loop in MM cells.
