Abstract:
Portulaca oleracea extracts, known as Ma Chi Hyun in the traditional Korean medicine, show a variety of biomedical efficacies including those in anti-inflammation and anti-allergy. In this study, we investigate the protective activity of the P. oleracea extracts against UVB-induced damage in human epithelial keratinocytes and fibroblasts by several apoptosis-related tests. The results suggest that P. oleracea extracts have protective effects from UVB-induced apoptosis.

Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
