The influence of topical PUVA on the activity of ornithine decarboxylase (ODC) and its gene expression was investigated in the skin of hairless mouse. After 1 h of application of 0.3% 8-methoxypsoralen, irradiation of 3 J/cm2 of ultraviolet A (UV-A) was administered. The ODC activity markedly increased and peaked at 24 h following UV-A irradiation. The ODC mRNA level, analyzed in dot-blot analysis, elevated to about 5 times that of control at 24 h after treatment. These results show that the PUVA-induced ODC activity is due in part to an increase in ODC gene expression.

UI MeSH Term Description Entries
D009955 Ornithine Decarboxylase A pyridoxal-phosphate protein, believed to be the rate-limiting compound in the biosynthesis of polyamines. It catalyzes the decarboxylation of ornithine to form putrescine, which is then linked to a propylamine moiety of decarboxylated S-adenosylmethionine to form spermidine.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012313 RNA A polynucleotide consisting essentially of chains with a repeating backbone of phosphate and ribose units to which nitrogenous bases are attached. RNA is unique among biological macromolecules in that it can encode genetic information, serve as an abundant structural component of cells, and also possesses catalytic activity.
