RNA oxidative damage and ribosomal RNA surveillance under oxidative stress
- Date Issued:
- 2012
- Summary:
- We have studies oxidative damage of RNA, a major type of cellular macromolecules. RNA is a primary target of reactive oxygen species (ROS). Under oxidative stress, most nucleic acid damages in Escherichia coli (E.coli) are present in RNA as shown by high levels of 8-oxo-G, an oxidized form of guanine. Increased RNA oxidation is closely correlated to cell death under oxidative stress. Surprisingly, neither RNA structure nor association with proteins protects RNA from oxidation... Our results demonstrate a major role for RNA degradation in controlling oxidized RNA. We have identified activities that may work in specific pathways for selectively degrading damaged RNA. These activities may play pivotal rold in controlling oxidized RNA and protecting cells under oxidative stress.
