Description
The Gene Ontology (GO) term GO:1902629, regulation of mRNA stability involved in cellular response to UV, defines a specialized biological process in which the stability of messenger RNAs is modulated as part of the cellular reaction to ultraviolet (UV) radiation. This process is distinct from general mRNA stability regulation because it is explicitly triggered by and integrated into the UV damage response, a stress that generates cyclobutane pyrimidine dimers and other photoproducts in both DNA and RNA. Cells must rapidly reprogram gene expression to survive UV-induced damage, and altering mRNA half-lives provides a fast and reversible mechanism to prioritize repair, survival, or apoptotic transcripts. Research into GO:1902629 has revealed that RNA-binding proteins such as cold-inducible RNA-binding protein (CIRBP) and NF90 are central to this regulation. For example, CIRBP responds to various cellular stresses, including UV, and can influence the stability of specific mRNAs. Similarly, NF90 (also known as ILF3) binds target RNAs and modulates their fate after UV exposure, as shown by iCLIP analyses. These molecular events are not merely housekeeping functions; they determine whether a cell repairs damage accurately or undergoes apoptosis, with direct implications for cancer biology and chemotherapy resistance. Understanding GO:1902629 is therefore critical for researchers in RNA biology, DNA repair, and oncology. The process intersects with the DNA damage response, as regulation of the RNA polymerase II pool is integral to surviving UV and other genotoxic stresses. Moreover, UV-induced changes in mRNA stability can be quantified by mass spectrometry and transcriptomic approaches, offering a systems-level view of the response. This article synthesizes current knowledge on the mechanisms, key genes, disease links, and experimental strategies—including CRISPR-based models—for studying this important GO term.

What Is GO:1902629?
GO:1902629 is defined as any regulation of mRNA stability that is involved in the cellular response to UV. In other words, it encompasses the molecular events that change the half-life of specific mRNAs when a cell is exposed to ultraviolet light, thereby contributing to the overall cellular defense against UV-induced damage. This regulation can involve stabilization or destabilization of transcripts and is carried out by RNA-binding proteins and signaling pathways that sense UV stress.
Why Is regulation of mRNA stability involved in cellular response to UV Important in Cell Biology?
GO:1902629 is important because it sits at the intersection of RNA metabolism and the DNA damage response, two fundamental processes that determine cell fate after UV exposure. UV radiation is a ubiquitous environmental carcinogen, and the ability of cells to rapidly adjust mRNA stability can mean the difference between efficient DNA repair and malignant transformation. By understanding how specific mRNAs are stabilized or degraded after UV, researchers can identify vulnerabilities in cancer cells, predict responses to radiotherapy, and develop targeted interventions that modulate this process for therapeutic benefit.
• UV radiation is a major cause of skin cancers, and mRNA stability regulation helps cells cope with UV-induced damage.
• This process enables rapid, post-transcriptional control of gene expression without requiring new transcription, which is especially valuable when UV damages DNA and stalls RNA polymerase II.
• Key regulators such as CIRBP are stress-responsive and influence cell survival, linking mRNA stability to broader stress adaptation.
• NF90 and other RNA-binding proteins shape the UV-responsive transcriptome, affecting mRNAs involved in proliferation and apoptosis.
• Dysregulation of mRNA stability after UV is associated with squamous cell carcinoma and may contribute to tumor progression.
• In non-small cell lung cancer, Y chromosome lncRNAs are involved in radiation response, highlighting broader roles for RNA regulation in genotoxic stress.
• Understanding this process can inform the development of radiosensitizers or chemotherapeutics that target RNA stability pathways.
• CRISPR screens can identify genes that regulate mRNA stability under UV, accelerating discovery of new therapeutic targets.
• The process is conserved and can be modeled in cell lines, making it accessible for mechanistic studies.
• Quantitative methods like mass spectrometry and iCLIP provide precise, genome-wide views of mRNA stability changes after UV.
What Happens During regulation of mRNA stability involved in cellular response to UV?
UV sensing and initial signaling
In simple terms: When UV light hits a cell, it damages molecules and triggers alarm signals that tell the cell to change which proteins it makes.
Upon UV exposure, cells detect damaged DNA and RNA, leading to activation of stress signaling pathways such as the DNA damage response. This includes phosphorylation of proteins like ATM/ATR and regulation of the RNA polymerase II pool, which is integral to the DNA damage response. These early signals set the stage for post-transcriptional changes, including alterations in mRNA stability. Mass spectrometry studies in HeLa cells have quantified the cellular response to UV, revealing rapid changes in protein abundance and modifications that influence RNA metabolism.
Recruitment of RNA-binding proteins to target mRNAs
In simple terms: Specialized proteins grab onto certain mRNA molecules and decide whether those mRNAs should be kept around longer or destroyed.
Key RNA-binding proteins such as CIRBP and NF90 are recruited to specific mRNAs after UV stress. CIRBP is a cold-inducible protein that responds to various cellular stresses, including UV, and can bind to mRNAs to modulate their stability. NF90 (ILF3) has been systematically mapped to target RNAs using iCLIP, revealing a network of transcripts whose stability may be regulated post-UV. Another protein, GLTSCR2/Pict-1, is expressed in skin squamous cell carcinomas and may influence mRNA stability pathways relevant to UV response.
mRNA stabilization or degradation
In simple terms: The fate of each mRNA is decided: some are protected from degradation and live longer, while others are quickly broken down.
The binding of regulatory proteins can either protect mRNAs from degradation or target them for decay. For example, CIRBP can stabilize certain transcripts under stress conditions, promoting cell survival. Conversely, other factors may recruit decay machinery. The net effect is a reprogrammed transcriptome that favors expression of repair and survival genes while reducing pro-apoptotic or unnecessary transcripts. This dynamic regulation is part of the broader cellular response to UV and is essential for maintaining genomic integrity.
Integration with translation and feedback
In simple terms: The changes in mRNA stability also affect how much protein is made, and the cell continuously adjusts this balance.
mRNA stability is tightly coupled to translation. Transcripts that are stabilized may be translated more efficiently, while destabilized mRNAs are removed from the translating pool. The regulation of the RNAPII pool during DNA damage also impacts the production of new transcripts, indirectly affecting the pool of mRNAs available for stability regulation. Feedback mechanisms ensure that the response is proportional to the extent of damage, and failure to properly regulate these processes can lead to cell death or malignant transformation.

How Is regulation of mRNA stability involved in cellular response to UV Regulated?
The regulation of mRNA stability involved in cellular response to UV is itself controlled by upstream signaling pathways. The DNA damage response kinases ATM and ATR are activated by UV-induced lesions and can modulate RNA-binding proteins and RNA polymerase II. CIRBP expression and activity are regulated by temperature shifts and other stresses, and its RNA-binding capacity can be influenced by post-translational modifications. NF90 activity may be controlled by phosphorylation and its interaction with other proteins. Additionally, the availability of RNA polymerase II, regulated during DNA damage, affects the pool of newly synthesized mRNAs that can be subject to stability control. These layers of regulation ensure a coordinated and dynamic response to UV.

Dysregulation of mRNA stability after UV can lead to inappropriate expression of oncogenes or loss of tumor suppressors, promoting carcinogenesis. Understanding GO:1902629 could reveal new targets for skin cancer prevention or therapy.
Radiation response in lung cancer
In male non-small cell lung cancer cells, Y chromosome lncRNAs are involved in the radiation response, suggesting that RNA-mediated regulation contributes to radiosensitivity. Although this study focused on radiation rather than UV, the principles of mRNA stability regulation under genotoxic stress are shared. Targeting these pathways might improve radiotherapy outcomes.

How CRISPR Can Be Used to Study GO:1902629 regulation of mRNA stability involved in cellular response to UV
Knockout
CRISPR knockout of candidate genes such as CIRBP, NF90, or GLTSCR2 allows researchers to test their requirement for UV-induced mRNA stability changes. By comparing mRNA half-lives in knockout versus wild-type cells after UV, one can determine whether the gene is essential for the process. This approach has been used to study RNA-binding proteins in stress responses.
Point Mutation
Point mutations can be introduced into genes encoding RNA-binding proteins to dissect specific domains or phosphorylation sites. For example, mutating a phosphorylation site in CIRBP may reveal its role in mRNA binding after UV. Similarly, point mutations in POLR2A can clarify how RNA polymerase II regulation affects mRNA stability.
Knock-in
Knock-in of tagged versions of proteins (e.g., GFP-NF90) enables iCLIP and live-cell imaging to track RNA-protein interactions after UV. This approach provides spatial and temporal resolution of mRNA stability regulation. Knock-in of reporter genes with specific 3'UTRs can also measure stability of individual transcripts.
Overexpression
Overexpression of wild-type or mutant forms of regulatory proteins can test sufficiency in driving mRNA stability changes. For instance, overexpressing GLTSCR2 in skin cancer cells may protect against UV-induced mRNA destabilization. Overexpression can also be combined with RNA-seq to identify downstream targets.
