1 Possible involvement of enhanced prostaglandin E2 production in the photosensitivity in xeroderma pigmentosum group A model mice. Dinoprostone xeroderma pigmentosum, complementation group A Mus musculus
2 In XPA-deficient mice, the amount of PGE2 significantly increased at 48 and 72 h after UVB irradiation to the level that was 8- and 16-fold higher than those in wild-type mice, respectively. Dinoprostone xeroderma pigmentosum, complementation group A Mus musculus
3 Treatment with indomethacin, a potent inhibitor of PG biosynthesis, inhibited UV-induced ear swelling, abrogated local immunosuppression, and decreased the amount of PGE2 in the ear skin of XPA-deficient mice. Dinoprostone xeroderma pigmentosum, complementation group A Mus musculus
4 The induced production of PGE2 may be involved in the enhanced inflammation and immunosuppression caused by UV radiation in XPA-deficient mice and XP patients. Dinoprostone xeroderma pigmentosum, complementation group A Mus musculus
