The chemopreventive effect of topical application of 4'-demethyl epipodophyllotoxin (DMEP), an antimitotic agent, on a two-stage skin carcinogenesis model in Swiss Albino mice induced by 9, 10-dimethylbenz[a]anthracene (DMBA)/12-O-tetradecanoylphorbol-13-acetate (TPA) was investigated. Two topical applications with 0.24% DMBA over 1 week, followed later by(More)
Epigallocatechin-3-gallate (EGCG) is an important chemopreventive agent derived from green tea. We recently reported that EGCG treatment enhances keratinocyte differentiation as evidenced by increased human involucrin promoter activity [Balasubramanian,S., Efimova,T. and Eckert,R.L. (2002) J. Biol. Chem., 277, 1828-1836]. In the present paper, we extend(More)
Epidermal squamous cell carcinoma is among the most common cancers in humans. These tumors are comprised of phenotypically diverse populations of cells that display varying potential for proliferation and differentiation. An important goal is identifying cells from this population that drive tumor formation. To enrich for tumor-forming cells, cancer cells(More)
