Abstract:
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.
Insights
Cells possess multiple mechanisms to repair RNA damage, crucial for survival and counteracting toxic effects. This review explores proteins involved in RNA damage avoidance and their links to human diseases.
Area of Science:
- Molecular Biology
- Cellular Biology
- Biochemistry
Background:
- Nucleic acid damaging agents frequently target both DNA and RNA.
- RNA damage can induce significant cellular toxicity, a principle exploited in cancer therapy.
- Existing knowledge on RNA damage repair is limited, with only one specific mechanism for methylated RNA damage identified.
Purpose of the Study:
- To review and discuss proteins involved in RNA damage avoidance mechanisms.
- To explore the potential roles of these proteins in various human diseases.
- To highlight the broader scope of cellular responses to RNA damage beyond currently known pathways.
Main Methods:
- Literature review of existing studies on RNA damage and repair.
- Analysis of protein functions related to nucleic acid damage response.
- Synthesis of data linking RNA damage avoidance pathways to human pathologies.
Main Results:
- Evidence suggests multiple proteins are involved in counteracting RNA damage.
- The known repair mechanisms for RNA damage are likely only a small part of a larger cellular defense system.
- Several proteins may play critical roles in mitigating the cytotoxic effects of diverse RNA lesions.
Conclusions:
- Cells have evolved sophisticated mechanisms to avoid RNA damage toxicity.
- Further research into RNA damage avoidance proteins is warranted.
- These proteins represent potential targets for understanding and treating human diseases.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
