Inhibition of carcinogenesis by dietary polyphenolic compounds.
This chapter reviews the inhibition of tumorigenesis by phenolic acids and derivatives, tea and catechins, isoflavones and soy preparations, quercetin and other flavonoids, resveratrol, and lignans as well as the mechanisms involved based on studies in vivo and in vitro. Expand
Inhibitory effects of dietary curcumin on forestomach, duodenal, and colon carcinogenesis in mice.
Results indicate that not only did curcumin inhibit the number of tumors per mouse and the percentage of mice with tumors but it also reduced tumor size. Expand

The inhibitory effects of curcumin, chlorogenic acid, caffeic acid, and ferulic acid on TPA-induced tumor promotion in mouse epidermis parallel their inhibitory effect on T PA-induced epidermal inflammation and epider mal lipoxygenase and cyclo oxygengenase activities. Expand
Inhibition of skin tumorigenesis by rosemary and its constituents carnosol and ursolic acid.
Topical application of carnosol or ursolic acid isolated from rosemary inhibited TPA-induced ear inflammation, ornithine decarboxylase activity, and tumor promotion and applied to mice previously initiated with DMBA inhibited the number of skin tumors per mouse. Expand
Inhibitory effect of curcumin, chlorogenic acid, caffeic acid, and ferulic acid on tumor promotion in mouse skin by 12-O-tetradecanoylphorbol-13-acetate.
The effects of topically applied curcumin, chlorogenic acid, caffeic acid, and ferulic acid on 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced epidermal ornithine decarboxylase activity, epidermal… Expand
Inhibition of N-nitrosodiethylamine- and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone-induced tumorigenesis in A/J mice by green tea and black tea.

An inhibitory action of green tea and black tea on nitrosamine-induced tumorigenesis is demonstrated and is clearly demonstrated. Expand
Effects of curcumin, demethoxycurcumin, bisdemethoxycurcumin and tetrahydrocurcumin on 12-O-tetradecanoylphorbol-13-acetate-induced tumor promotion.
Topical application of commercial grade curcumin or demethoxycurcumin had an equally potent inhibitory effect on 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced increases in ornithine decarboxylase activity and TPA-induced tumor promotion in 7,12-dimethylbenz[a]anthracene-initiated mouse skin.

Inhibitory effect of green tea in the drinking water on tumorigenesis by ultraviolet light and 12-O-tetradecanoylphorbol-13-acetate in the skin of SKH-1 mice.
Treatment of the animals with the green tea extract not only decreased the number of skin tumors but also decreased substantially the size of the tumors. Expand
Stimulatory effect of oral administration of green tea or caffeine on ultraviolet light-induced increases in epidermal wild-type p53, p21(WAF1/CIP1), and apoptotic sunburn cells in SKH-1 mice.
The stimulatory effect of green tea and caffeine on UV-induced increases in the number of p53-positive cells, p21(WAF1/CIP1)- positive cells, and apoptotic sunburn cells may play a role in the inhibitory effects of tea and caffeinated drinks onUV-induced carcinogenesis. Expand
Inhibition of tumor promoter-mediated processes in mouse skin and bovine lens by caffeic acid phenethyl ester.
Findings point to CAPE as being a potent chemopreventive agent, which may be useful in combating diseases with strong inflammatory and/or oxidative stress components, i.e., various types of cancer and possibly cataract development. Expand
