Description

Induction of photolyase activity was studied in cultured frog cells using clonogenic assays. Exposure of arrested cells to a pre-irradiation (90% survival) of 254 nm ultraviolet light resulted in a transient enhancement of photolyase activity. Cells expressed a decreased level of photolyase activity in response to an equitoxic fluence of simulated sunlight wavelengths 280-310 nm. However, no significant increase of enzyme activity was detected in cells following treatment with sunlight wavelengths 310-330 nm. In addition, this process depends on newly biosynthesized protein(s)
