"DNA damage; apoptosis; oxidative stress; UVB; rosmarinic acid; Prunella vulgaris"@en . . . "Solar light is an important factor in skin pathogenesis and the development of a number of skin disorders. UVB irradiation is known to induce oxidative stress, inflammation and DNA lesions in exposed cells. Natural compounds have been studied for their ability to modulate various lifestyle-related diseases. The use of plant compounds/extracts with screening, antioxidant and anti-inflammatory activities may also successfully protect the skin against UV-caused injury. We assessed the potency of Prunella vulgaris extract (PVE) and its main phenolic acid component, rosmarinic acid (RA), to suppress UVB-induced alterations to keratinocytes HaCaT using a solar simulator. Pre- and post-treatment of HaCaT cells with PVE (5-50 mg/l) and RA (0.18-1.8 mg/l) reduced breakage together with the apoptotic process. PVE and RA also significantly eliminated ROS production and diminished IL-6 release. Both PVE and RA prevent UVB-caused injury to keratinocytes. However their efficacy needs to be demonstrated in vivo."@en . "Archives of Dermatological Research" .
