NFKB1 and lung carcinoma: Extended from our previous studies showing that concurrent blockage of the NF-κB and Akt signaling pathways sensitizes lung cancer cells to cisplatin-induced apoptosis, we for the first time found that knockdown of Akt1 and the NF-κB-activating kinase IKKβ cooperatively downregulated histone H4 expression, which increased cisplatin-induced apoptosis in lung cancer cells.
