As reported, most proteins are degraded through ubiquitin‐proteasome pathway.23 To explore whether degrasyn degrades WT1 protein through ubiquitin‐proteasome pathway, degrasyn‐treated pancreatic cancer cells were incubated with or without MG132, an inhibitor for ubiquitin‐proteasome pathway. This evidence concerns the gene WT1 and pancreatic neoplasm.
