July 2013 in “Amino Acids” Elevated ornithine decarboxylase (ODC) activity in the epidermis was found to promote skin tumor development by recruiting hair follicle bulge stem cells, as demonstrated in ODC-ER transgenic mice. The study showed that inducing ODC activity with 4-hydroxytamoxifen (4OHT) was sufficient to recruit these stem cells in quiescent skin. Although increased ODC activity also led to higher reactive oxygen species (ROS) generation, the use of the polyamine catabolic oxidase inhibitor MDL72527 revealed that ROS generation did not contribute to tumorigenesis. Instead, MDL72527 treatment resulted in a shorter tumor latency, increased tumor burden, and more carcinomas, indicating that the recruitment of bulge stem cells, rather than ROS, played a key role in tumor promotion.
