Several studies have reported that ASK can induce apoptosis in different cancer cells and exhibit antitumour activities against oral squamous cells, melanoma cells and colorectal cells.19, 20, 21, 22 Our previous study showed that ASK can inhibit the proliferation of human chronic myelogenous leukaemia K562 cells and induce apoptosis by blocking NF‐κB signalling and depleting Bcr‐Abl.32 The gene discussed is NFKB1; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
