Similarly to the data reported by Roulois et al (2015) in colorectal cancer cells, DAC treatment of MDA‐MB‐231 and HMLER cells induced the interferon regulatory factor 7 (IRF7), a key player in the type I interferon (IFN)‐dependent immune responses (Appendix Fig S6C and D). This evidence concerns the gene IFNA1 and colorectal cancer.
