Description
GO:0009314 response to radiation is a biological process defined as 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 an electromagnetic radiation stimulus [QuickGO]. Electromagnetic radiation is a propagating wave in space with electric and magnetic components that oscillate at right angles to each other and to the direction of propagation. This term encompasses responses to a wide spectrum of radiation, from ultraviolet (UV) and visible light to infrared, microwave, and radiofrequency fields [1, 2, 3]. Researchers study this process to understand how organisms sense and adapt to electromagnetic environments, with implications for photobiology, radiation protection, and therapeutic development [6, 7]. The response involves rapid molecular events such as ROS generation, microRNA regulation, and immune cell activation, as well as longer-term changes in gene expression and cellular regeneration [1, 6, 8].

What Happens During response to radiation?
Radiation sensing and immediate molecular events
In simple terms: When cells encounter electromagnetic radiation, they first sense it and trigger rapid molecular changes.
Electromagnetic radiation, such as UV-A to red light, can induce reactive oxygen species (ROS) production within cells, leading to oxidative stress and activation of signaling pathways. Light-regulated microRNAs are rapidly modulated, affecting post-transcriptional gene silencing. In neutrophils, radiation enhances the response to particulate agonists, indicating a priming effect on immune cells.
Signal transduction and gene expression changes
In simple terms: The initial signals are amplified and transmitted to the nucleus, changing which genes are turned on or off.
Radiation exposure leads to changes in gene expression, including upregulation of stress-responsive genes and microRNAs. Coarse-grained model simulations of microwave radiation show biomolecular responses that may involve conformational changes in proteins and nucleic acids. In adrenocorticocytes, low-intensity electromagnetic radiation promotes intracellular regeneration, likely through altered gene expression programs.
Cellular effector responses
In simple terms: Cells then carry out specific actions, such as releasing traps or regenerating organelles, in response to radiation.
UV-A to red light induces ROS-dependent release of neutrophil extracellular traps (NETs), a form of innate immune response. Extremely high-frequency electromagnetic radiation enhances neutrophil response to particulate agonists, suggesting increased phagocytic or degranulation activity. Ticks exposed to radiofrequency electromagnetic radiation show behavioral changes, indicating organism-level responses.
Tissue and organismal adaptation
In simple terms: Over longer periods, radiation exposure can lead to adaptive changes in tissues and whole organisms.
Prophylactic application of low-intensity electromagnetic radiation under radiation conditions promotes intracellular regeneration of adrenocorticocytes, suggesting tissue-protective effects. Behavioral responses in ticks demonstrate that even simple organisms can detect and react to radiofrequency fields. These adaptations may involve systemic signaling and epigenetic modifications [1, 8].

How Is response to radiation Regulated?
The response to radiation is regulated at multiple levels. MicroRNAs fine-tune gene expression post-transcriptionally, and light exposure can alter microRNA levels. ROS production activates redox-sensitive transcription factors such as NRF2 and NF-κB, which coordinate antioxidant and inflammatory programs. In neutrophils, radiation primes cells for enhanced responses to agonists, involving kinase cascades. Low-intensity electromagnetic radiation can promote intracellular regeneration, possibly through growth factor signaling. Computational models suggest that microwave radiation directly affects biomolecular dynamics.

Radiation and cancer
Radiation is a known carcinogen, and cellular responses to radiation influence cancer risk and treatment outcomes. UV radiation causes DNA damage and modulates microRNAs that can act as oncogenes or tumor suppressors. ROS-dependent NET release may contribute to inflammation-associated carcinogenesis. Understanding these pathways can inform radiotherapy and photodynamic therapy.
Immune dysfunction and inflammation
Electromagnetic radiation can modulate immune cell function. Extremely high-frequency electromagnetic radiation enhances neutrophil responses, which may exacerbate inflammatory diseases. UV-A to red light induces NET release, linking radiation to autoimmunity and tissue damage. Dysregulated radiation responses may contribute to chronic inflammatory conditions [3, 6].
Endocrine and metabolic disorders
Low-intensity electromagnetic radiation affects adrenocorticocytes, cells of the adrenal cortex, promoting intracellular regeneration under radiation stress. This suggests potential impacts on endocrine function and stress responses. Disruption of these processes may contribute to metabolic and hormonal disorders.

How CRISPR Can Be Used to Study GO:0009314 response to radiation
Knockout
CRISPR knockout of candidate genes such as DICER1, CYBB, or PADI4 can test their requirement for radiation-induced microRNA processing, ROS production, or NET release [1, 6]. Knockout cell lines provide causal evidence for gene function in the response to radiation.
Point Mutation
Point mutations can mimic disease-associated variants or inactivate catalytic residues. For example, a NOX2 point mutation can abolish ROS production and NET release after UV radiation. Point-mutation knock-in models are valuable for dissecting signaling mechanisms.
Knock-in
Knock-in of tagged or reporter genes allows real-time monitoring of radiation responses. For instance, tagging HIF1A with a fluorescent protein enables tracking of its stabilization after radiation-induced ROS. Knock-in models also facilitate drug screening.
Overexpression
Overexpression of protective genes such as HSPA1A (HSP70) or NFE2L2 (NRF2) can test whether increased levels confer resistance to radiation-induced stress [4, 6]. Overexpression models are useful for gain-of-function studies.
