CAFs activated the NF-κB pathway in irradiated NPC cells. a CAFs activated the NF-κB pathway in irradiated NPC cells. b Treatment with an IL-8 receptor antagonist inhibited activation of the NF-κB pathway in irradiated NPC cells. c The proliferation of NPC cell lines was evaluated by a CCK-8 assay under a wide-range of concentrations of CAPE. d and e A blockade of the NF-κB pathway with CAPE (2 μM) inhibited the recovery of NPC cells after irradiation. * P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.0001, ns, no significance
