When human colon cancer HCT116, CX-1, and LS174T cells were treated with ferroptotic agents such as sorafenib (SRF), erastin, and artesunate, data from immunoblot assay showed that ferroptotic agents induced endoplasmic reticulum (ER) stress and the ER stress response-mediated expression of death receptor 5 (DR5), but not death receptor 4.
In conclusion, our results showed that BAY61-3606 sensitizes colon cancer cells to TRAIL-induced apoptosis via up-regulating DR4 expression in p53-dependent manner and inhibiting NF-κB activity, suggesting that the combination of TRAIL and BAY61-3606 may be a promising therapeutic approach in the treatment of colon cancer.
