Two UVC-induced stress response pathways in HeLa cells identified by cDNA microarray.

Environmental toxins induce multiple effects in vivo, involving various molecular pathways. The ultraviolet C (UVC, 254 nm) component of sunlight can cause strong cytotoxic and genotoxic effects. In this study, UVC-induced stress response factors were analyzed by cDNA microarray, using the Millennium(R) Nylon membrane chip system.
