Most of nucleic acids damaging agents are not only restricted to DNA but equally affect DNA and RNA molecules. Considering that RNA damage could be very toxic for the cell, a property used by some cancer treatments, it would not be unexpected to find out that several proteins may be involved in RNA damage avoidance mechanisms helping cells to counteract such cytotoxic effects. Up to now, only one specific repair mechanism allowing cells to deal with toxic effects of methylated RNA have been described. However, there are in the literature several data suggesting that this study may only be the tip of the iceberg and that cells might be able to counteract the deleterious effects of a large variety of RNA damage. In this review, we will discuss the different proteins that may be involved in the mechanism of RNA damage avoidance and their potential role in human diseases.
