March 2004 in “Journal of Clinical Investigation” In this study, overexpression of ornithine decarboxylase accelerated basal cell carcinoma in Ptch1+/– mice under UVB exposure, while its inhibition reduced tumor induction, suggesting potential chemoprevention strategies in humans.

March 2004 in “Journal of Clinical Investigation” This study found that inhibiting the enzyme ornithine decarboxylase (ODC) prevented UVB-induced basal cell carcinomas in a mouse model, suggesting ODC is a potential target for chemoprevention strategies.

,
June 2003 in “PubMed” In this study, severe hair loss occurred in PKC epsilon transgenic mice treated with DFMO during skin tumor prevention, highlighting a link between polyamine biosynthesis, hair follicle maintenance, and metastasis suppression.
54 citations
,
February 2002 in “Carcinogenesis” This study suggests that activation of polyamine catabolism in K6-SSAT transgenic mice may significantly increase skin tumor development and progression to carcinomas following chemical induction.
88 citations
,
August 1998 in “Carcinogenesis” This study found that overexpression of ornithine decarboxylase and activated Ha-ras together led to a high rate of tumor development in a mouse model without additional carcinogens.
153 citations
,
April 1998 in “Current Biology” This study found that benign tumors with a high risk of malignant progression primarily arise from hair follicle cells when a mutant ras gene is expressed in a specific population of epidermal cells in mice.
233 citations
,
July 1997 in “PubMed” In this study, targeting ornithine decarboxylase overexpression to hair follicle keratinocytes in mice was sufficient to promote skin tumor development without additional tumor promoters.

May 1995 in “Proceedings of the National Academy of Sciences” This study demonstrated that a specific 9-kbp fragment of the bovine keratin 6 gene effectively directs tissue-specific and inducible expression in transgenic mice, suggesting potential applications for targeted gene therapy in hyperproliferative skin conditions.
