DABIL‐4 exhibits cytotoxic activity against IL‐4R+ TNBC cells. (A) Activity of DABIL‐4 against 4T1 cells in an MTS assay showed an IC50 of 2 nm, while (B) after heat inactivation, it showed no cytotoxicity. (C) Recombinant IL‐4, in a dose‐dependent fashion, blocked the cytotoxic activity of 25 nm DABIL‐4 in an MTS assay with 4T1. (D) Activity of DABIL‐4 against E0771 cells in an MTS assay showed an IC50 of 4 nm. Data are shown as mean ± SD. The experiments were performed in at least triplicates.
