September 1999 in “Molecular Carcinogenesis” A transgenic mouse model was developed to overexpress ornithine decarboxylase (ODC) specifically in hair follicle keratinocytes using a regulated system. In the absence of doxycycline, these mice showed high levels of epidermal ODC activity and hyperplasia when exposed to the tumor promoter TPA, particularly affecting hair follicles. This effect was reversed by adding doxycycline, which repressed transgene expression. The study found that increased ODC expression made the typically tumor promotion-resistant C57Bl/6 mice more sensitive to TPA's effects, as evidenced by a reduction in papilloma development when ODC expression was repressed.
September 1999 in “Molecular Carcinogenesis” The study developed a transgenic mouse model to investigate the role of ornithine decarboxylase (ODC) in tumor promotion. By using a tetracycline-regulated system, researchers were able to overexpress ODC specifically in hair follicle keratinocytes of C57Bl/6 mice. In the absence of doxycycline, these mice showed high levels of epidermal ODC activity and hyperplasia when exposed to the tumor promoter TPA, particularly affecting hair follicles. This increased ODC expression made the typically tumor-resistant C57Bl/6 mice more sensitive to tumor-promoting effects. However, when doxycycline was used to repress ODC expression, the number of papillomas was significantly reduced, demonstrating the critical role of ODC in tumor promotion.
