Abstract excerpt
8-Methoxypsoralen (8-MOP) plus UVA irradiation (PUVA therapy) has been used for the treatment of psoriasis. PUVA therapy has been associated with an increased risk of developing skin squamous cell carcinoma (SCC). In order to determine the PUVA-induced p53 mutation spectrum, a yeast expression vector harbouring a human wild-type p53 cDNA was incubated with 8-MOP, and UVA irradiated in vitro. PUVA-damaged and...
