AB - Mice of the inbred strain DBA/2 responded to a two-stage, initiation-promotion tumorigenesis protocol when high initiating doses (400 nmol/mouse) of 7,12-dimethylbenz[a]- anthracene were utilized. They also responded when N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) was used as the initiating agent. The tumor response in both cases was characterized by a rapid rate of tumor development with the maximal tumor responses reached on or before the 15th week of promotion with 12-O-tetradecanoylphorbol-13-acetate (TPA). When DBA/2 mice were compared with SENCAR mice for promotion sensitivity following initiation with MNNG, the two mouse stocks responded with a nearly identical tumor response. C57BL/6 mice were essentially resistant to TPA promotion regardless of the initiator or the dose of initiator used. A preliminary study was conducted to determine how susceptibility to tumor promotion by TPA was inherited in F1mice derived from DBA/2 (sensitive) and C57BL/6 (resistant) parents. The B6D2F1mice were as sensitive as the DBA/2 parent, suggesting that susceptibility in these two inbred mouse strains is inherited as an autosoma1 dominant trait. The results show that these two inbred mouse strains may provide a model system for studying genetic factors controlling susceptibility to phorbol ester skin tumor promotion.
TI - DBA/2 mice are as sensitive as SENCAR mice to skin tumor promotion by 12-O-tetradecanoylphorbol-13-acetate
