G S Cameron et al.
Cancer research, 51(20), 5642-5648 (1991-10-15)
The ability of the hyperplasiogenic irritant ethyl phenylpropiolate (EPP) to act as a tumor promoter in two-stage carcinogenesis and to stimulate cellular events commonly cited as markers of tumor promoter action was evaluated. Treatment of adult, inbred SENCAR (SSIN) mice
J E Paulsen
Carcinogenesis, 11(8), 1255-1258 (1990-08-01)
We examined the effects of retinoic acid (RA) on epidermal DNA synthesis, induced by 12-O-tetradecanoylphorbol-13-acetate (TPA), a strong tumor promoter; mezerein (MEZ), a strong second stage promoter or ethylphenylpropiolate (EPP), a weak tumor promoter. RA reduced the initial wave of
K A Davidson et al.
The Journal of investigative dermatology, 79(6), 378-382 (1982-12-01)
Glucocorticoids (anti-inflammatory steroids) are very potent inhibitors of mouse skin tumor promotion induced by 12-O-tetradecanoylphorbol-13-acetate (TPA). This report describes a high-affinity, limited-capacity binding component which specifically interacts with glucocorticoids and which is identified as a glucocorticoid (GC) receptor present in
M Takigawa et al.
Cancer research, 46(1), 106-112 (1986-01-01)
More than one application of the potent tumor-promoting agent, 12-O-tetradecanoylphorbol-13-acetate (TPA), to mouse skin at intervals of more than 48 h led to a larger induction of ornithine decarboxylase (EC 4.1.1.17; ODC) than did a single application. In contrast, at
C McGaughey et al.
Journal of toxicology and environmental health, 11(3), 467-474 (1983-03-01)
Tumor initiation by topical application of 7,12-dimethylbenz[a]anthracene (DMBA) in dimethyl sulfoxide (DMSO) followed by topical application of retinyl acetate (RA), ethylphenylpropiolate, or acetic acid in DMSO at inflammatory and hyperplasiogenic dose regimens caused the rapid promotion of fibrovascular polyps with
