Is the autophagy-inducing drug carbamazepine a radiation protector and mitigator? Context: To determine whether Carbamazepine (CBZ) is a radiation protector and/or mitigator. Murine hematopoietic progenitor 32D cl 3 cells were incubated in 1, 10, or 100 μM CBZ 1 h before or immediately after 0-8 Gy irradiation and assayed for clonogenic survival. Autophagy was assayed by immunoblot for microtubule-associated protein light chain 3 (LC3). In vivo radioprotection and mitigation were determined with C57BL/6NTac mice. CBZ treatment at 1, 10 or 100 μM for 1 h prior to irradiation increased radioresistance (the dose for 37% survival or D(0)) from control 1.5 ± 0.1 Gy to 2.1 ± 0.2 Gy (P = 0.012), 2.3 ± 0.1 Gy (P = 0.010), and 3.6 ± 0.7 Gy (P = 0.003), respectively; after irradiation increased the extrapolation number (ñ) from 1.5 ± 0.3 to 10.1 ± 4.2 (P = 0.011), 5.5 ± 1.7 (P = 0.019), and 3.6 ± 0.8 (P = 0.014), respectively, and increased autophagy. CBZ treated mice 10 min or 24 h before or 10 min or 12 h after 9.25 Gy total body irradiation (TBI) showed increased survival (P = 0.012, 0.011, 0.0002, and 0.017, respectively).

CBZ may be a useful radiation protector and mitigator. Final Decision: yes
