DACT also stimulated all ICD hallmarks (eIF2α phosphorylation, CALR exposure, ATP and HMGB1 release, as well as induction of type 1 interferon‐related metagene) in another cell line, the murine methylcholanthrene‐induced fibrosarcoma MCA205 (Fig EV1). The gene discussed is EIF2A; the disease is fibrosarcoma.
