Summary
Cells prevent RNA damage from oxidative stress using surveillance mechanisms. These systems remove damaged RNA and block oxidized nucleotides during synthesis, maintaining cellular health and preventing disease.
Area of Science:
- Molecular Biology
- Cellular Biology
- Biochemistry
Background:
- Oxidative stress and degenerative diseases increase RNA damage, exceeding DNA damage levels.
- RNA oxidation can impair crucial cellular functions like protein synthesis.
- Cells possess mechanisms to counteract RNA damage, highlighting its significance.
Purpose of the Study:
- To investigate the cellular mechanisms that prevent and repair oxidative damage to RNA.
- To understand the role of RNA surveillance in preventing disease associated with RNA oxidation.
Main Methods:
- Review of existing literature on RNA oxidation and cellular repair pathways.
- Analysis of molecular and cellular consequences of RNA damage.
- Examination of RNA surveillance mechanisms involved in damage control.
Main Results:
- Oxidative damage to RNA is prevalent under stress and in disease states.
- Cells employ specific proteins to identify and degrade oxidatively damaged RNA.
- Mechanisms exist to prevent the incorporation of oxidized nucleotides during RNA synthesis.
Conclusions:
- RNA oxidation is a significant threat to cellular function and health.
- Cellular RNA surveillance mechanisms are critical for preventing disease.
- Maintaining RNA integrity is essential for cellular homeostasis and survival.

DNA Distortion and Damage
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...

Overview
02:25Overview of DNA Repair
In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.

01:35Mutations
Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.

02:36DNA Damage can Stall the Cell Cycle
In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...
