To confirm the significance of NFkB signal in cancer-derived myocardial disorder, we examined maturity of H9c2 cells by measuring SDS-MYL1 after H9c2 cells exposed to CT26-inoculated mouse ascites with or without an IKKbeta inhibitor, IMD0354 (Figure 4D). The gene discussed is NFKB1; the disease is myocardial disorder.
