MYC and Miyoshi myopathy: In the present study, we found that HVJ-E-induced cell death was dependent on the downregulation of c-Myc (Figure 4E) and that the intracellular Ca2+ chelator BAPTA-AM prevented the HVJ-E-induced c-Myc downregulation (Figure 4F and Figure 6E) and cell death of MM cells (Figure 3B).
