Liver cancer is the leading cause of cancer mortality worldwide. Despite the improved treatment of HCC, the 5-year survival rate is relatively lower than other cancers, therefore further research to identify a new target is needed.
Caspase-10 is a human-only protein that is highly homologous to caspase-8. Both caspase-10 and caspase-8 are known to activate apoptosis. Given that caspase-10 is highly homologous to caspase-8, it has been reported that there is overlap between the substrate of caspases. However, recent studies reported that caspase-10 might have a distinct role in cancer cell death that differs from that of caspase-8.
To elucidate the mechanism of caspase-10 in cancer, we generated a caspase-10 knock-out cell line and performed RNA-seq analysis. In this study, we identified that caspase-10 induces pyroptosis. We show that caspase-10 mediates pyroptosis by cleaving GSDME under the treatment of sorafenib.
Recently, switching from apoptosis to other types of programmed cell death such as pyroptosis has emerged as a new strategy for cancer treatment.
Our findings suggest that targeting caspase-10 can be a potential therapy for patients with liver cancer.
