## BACKGROUND. Ornithine decarboxylase (ODC) is a key rate-limiting enzyme in polyamine biosynthesis. Several studies using an enzyme assay revealed that the ODC activity was higher in tumor tissue than in normal tissue. However, there is little information on the mRNA status of ODC in surgical sp

β¦ Synopsis
Using in situ hybridization techniques, we examined the expression of ornithine decarboxylase (ODC) mRNA in the skin of five patients with systemic sclerosis (SSc) and five normal controls. Sections treated with an anti-sense probe showed concentrated grains exclusively in the epidermis of SSc patients, but not in that of normal controls. Because our subcloned anti-sense probe specifically hybridizes with ODC mRNA, these findings indicate that the expression of ODC mRNA is elevated in SSc epidermis. Possibly polyamines have an important part to play in the skin changes of SSc.

## Abstract This study was undertaken to assess the effects of a single or two sequential topical applications of 12β__O__βtetradecanoylphorbolβ13βacetate (TPA) on the expression of cβ__fos__, cβ__jun__, junB, cβ__myc__, and ornithine decarboxylase (__ODC__) in promotionβsensitive SSIN mice and the
