August 2014 in “Biochemical and Biophysical Research Communications” The study investigated the role of ornithine decarboxylase (ODC) in skin carcinogenesis by using genetically modified mice to direct ODC expression to specific epidermal compartments. It was found that K6-driven ODC over-expression in the outer root sheath of hair follicles significantly increased tumorigenesis compared to K14-driven ODC expression in inter-follicular epidermal keratinocytes. Mice with K6-ODC expression developed an average of 15 tumors per mouse, while K14-ODC mice developed 6.8 tumors per mouse. The K6-ODC mice also showed higher UVB-induced proliferation, pro-inflammatory responses, and a greater number of stem-like cells, with reduced Notch1 expression linked to stem cell expansion. The study concluded that ODC enhances tumorigenesis by negatively regulating the Notch pathway, leading to an expansion of the stem cell compartment.
