We purchased WT C57BL/6 mice from Koatech (Pyeongtaek, Korea). The G2A knockout (KO) mice (36 (link)) on the C57BL/6 background, as we described previously, we received from Dr. DK Song (Hallym University). We did all animal experiments in accordance with guidelines and approval of the International Animal Care and Use Committees of Hallym University (Hallym 2018-9, 2019-18).
