In liver cancer, the presence of tumour-initiating cell subsets are associated with poorer prognosis and chemotherapy resistance in liver cancer. Here, the authors show that upon treatment with 5-FU or cisplatin, this subset releases SPINK1 which binds EGFR, activating the ERK-CDK4/6-E2F2 signaling cascade and resulting in chemoresistance.
