IL24 and breast carcinoma: PKA stimulated phosphorylation of p38 MAPK at threonine 180 and tyrosine 182 residues in MCF‐7 breast cancer cells, leading to the upregulation of Fas, FasL, DR4, and FADD levels, all indicative of an activated extrinsic apoptotic pathway following IL‐24 treatment (Persaud et al. 2018).
