Abstract:
Riboflavin can be photosensitized to produce reactive oxygen species. In the present study, a DNA damage assay was developed based on the photo reaction of riboflavin. In this test system, oxyresveratrol showed higher DNA protective effect than the well-known antioxidants Trolox and ascorbic acid. The results suggest potential applications for oxyresveratrol as an anti-aging agent and a riboflavin stabilizer.

Nucleotide Excision Repair
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...
