Abstract:
In vitro-synthesized mRNA containing nucleoside modifications has great therapeutical potential to transiently express proteins with physiological importance. One such protein is photolyase which rapidly removes UV-induced DNA damages, but this enzyme is absent in humans. Here, we apply a novel mRNA-based platform to achieve functional nonhuman photolyase production in cultured human keratinocytes. Transfection of nucleoside-modified mRNA encoding photolyase leads to accelerated repair of DNA photolesions in human keratinocytes.

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...
