To gain insight into the relationship of the FL118‐binding DDX5 with the FL118 inhibition of survivin, Mcl‐1, XIAP and cIAP2, we silenced and overexpressed DDX5 in PDAC Panc1 (Figures 3A and S4A) and CRC HCT‐8 (Figures 3B and S4B) cells. This evidence concerns the gene MCL1 and colorectal carcinoma.
