neoplasm
• one mouse treated with acetone in 7,12-dimethylbenz[a]anthracene (DMBA) developed 4 papilomas of greater than 1 mm3 at week 14
• however, mice treated with TPA in DMBA develop skin papillomas at the same rate of latency and incidence as wild-type mice
• at week 19 of treated with 12-O-tetradecanoylphorbol-13-acetate (TPA) in DMBA, mice exhibit an increase of 2.7-fold in the average number of papillomas and the number of papillomas per mouse compared to similarly treated wild-type mice
• mice treated with TPA in DMEA exhibit a higher frequency of larger tumors (1 to 5 and greater than 5 mm3) compared to similarly treated wild-type mice (1.2 and 1.4 compared to 0.6 and 0.6)

integument
• proliferation in the skin is increased relative to in wild-type mice
|
• in mice either treated with acetone in 7,12-dimethylbenz[a]anthracene (DMBA) or 12-O-tetradecanoylphorbol-13-acetate (TPA) in DMBA, epidermal thickness is increased (26.17+/-24.03 um and 84.86+/-42.53 um, respectively, compared to 10.0+/-0.00 um and 62.73+/-35.97 um, respectively, in wild-type mice)
