Similar findings have been made recently using a different model: T-cell specific acute deletion of mnt and a ROSA-26 locus-driven mycT58A mutant transgene.30 While mycT58A mice succumbed to thymic lymphomas with a median survival of 220 days, mnt deletion resulted in a median survival of 355 days and none of the mnt-/−mycT58A mice developed thymic lymphoma. Here, MNT is linked to thymus lymphoma.
