response to ozone

Definition

Target type: biologicalprocess

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a ozone stimulus. [GOC:sm]

Ozone is a powerful oxidant that can cause significant damage to living organisms. Upon exposure to ozone, cells initiate a complex series of responses aimed at mitigating its harmful effects. These responses involve a coordinated effort of multiple cellular pathways, including oxidative stress signaling, DNA repair mechanisms, and antioxidant defense systems.

Firstly, ozone can directly react with cellular components, including lipids, proteins, and DNA, leading to oxidative stress. This oxidative stress is characterized by an imbalance between the production of reactive oxygen species (ROS) and the antioxidant defense systems. Ozone-induced ROS can trigger various signaling pathways, including the activation of transcription factors like NF-κB and AP-1, which regulate the expression of genes involved in inflammation and immune responses.

Secondly, ozone can damage DNA, leading to the formation of DNA adducts and strand breaks. To repair these damages, cells activate DNA repair pathways, such as nucleotide excision repair and base excision repair, to restore the integrity of the genome. These repair pathways involve a series of enzymes that remove damaged nucleotides and replace them with the correct ones.

Thirdly, to combat the oxidative stress caused by ozone, cells activate antioxidant defense systems. These systems include enzymes like superoxide dismutase (SOD), catalase, and glutathione peroxidase, which neutralize ROS and prevent oxidative damage. In addition, cells can also produce antioxidants like glutathione and vitamins C and E, which can directly scavenge free radicals.

Overall, the response to ozone is a multifaceted process involving complex cellular signaling pathways, DNA repair mechanisms, and antioxidant defenses. These responses are essential for mitigating the damaging effects of ozone and maintaining cellular homeostasis.'
