For example, degrasyn induces proteasomal‐dependent degradation of c‐Myc in multiple myeloma.19 Moreover, degrasyn facilitates doxorubicin sensitivity through USP9x‐dependent degradation of p53 in hepatocellular carcinoma cells.31 Consistent with these reports, we found that degrasyn rapidly induces proteasomal‐dependent degradation of WT1 protein in pancreatic cancer cells. This evidence concerns the gene USP9X and pancreatic neoplasm.
