Abstract

The 12/15-lipoxygenase (12/15-LOX) pathways of arachidonate metabolism have been implicated in the pathogenesis of psoriasis. Since UV photo-therapy is a commonly used technique for inhibiting cell proliferation and inflammation in skin diseases, we hypothesized that UV-irradiation may affect 12/15-LOX expression which might regulate cell proliferation. In this study, we showed that UV-irradiation suppressed 12-LOX expression, whereas up-regulated 15-LOX expression. Treatment with the 15-LOX metabolites sufficiently suppressed insulin-like growth factor II-induced 12-LOX expression and blocked cell cycle progression. On the basis of our findings, we think that the 15-LOX metabolites may inhibit epidermal hyperplasia in psoriasis by regulating 12-LOX expression.
