Description
GO:1904586, cellular response to putrescine, is a Gene Ontology biological process term defined as any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a putrescine stimulus. Putrescine (1,4-butanediamine) is a small aliphatic diamine and a key intermediate in polyamine metabolism, and its cellular effects are conserved from bacteria to plants and mammals [2, 4]. Because putrescine can act as a metabolic substrate, a signaling molecule and a stress-associated metabolite, the cellular response to putrescine integrates transport, catabolism, gene expression and oxidative balance [4, 5, 8]. Researchers study GO:1904586 to understand how cells sense and adapt to changing polyamine levels. In Escherichia coli, putrescine catabolism is induced as a metabolic response to several stresses, showing that this response is part of a broader stress program. In plants, putrescine accumulates in response to abiotic stress and contributes to 4-aminobutyrate (GABA) production, and it regulates abscisic acid levels during cold acclimation and freezing tolerance [2, 7]. In human cells, putrescine has been used as an indicator of manganese neurotoxicity in SH-SY5Y cells, and cellular responses to polyamine oxidation products involve glucose and glutathione metabolism [3, 8]. This article summarizes the definition, mechanism, key genes, disease relevance and research methods for GO:1904586, with an emphasis on how CRISPR-based cell models can be used to test causal roles of candidate genes in the cellular response to putrescine.

What Is GO:1904586?
In plain terms, GO:1904586 describes everything a cell does when it encounters putrescine. Formally, it is any process that changes a cell's state or activity, such as movement, secretion, enzyme production or gene expression, as a result of a putrescine stimulus. The term covers the sensing of putrescine, the downstream signaling and metabolic adjustments, and the resulting cellular outputs. It is a biological process term and includes responses to putrescine itself and to putrescine-derived signals where these are part of the cellular reaction to the putrescine stimulus.
Why Is cellular response to putrescine Important in Cell Biology?
GO:1904586 matters because putrescine is not merely a metabolic intermediate; it is a signal and stress-associated metabolite that cells must sense and respond to. In bacteria, putrescine catabolism is part of the metabolic response to several stresses, which has implications for survival under adverse conditions. In plants, putrescine accumulation contributes to GABA production and to cold acclimation through abscisic acid regulation, making this response central to abiotic stress tolerance [2, 7]. In mammals, putrescine levels change in response to neurotoxic metals such as manganese, and polyamine oxidation products elicit cellular responses involving glucose and glutathione, linking this process to oxidative stress and neurotoxicity [3, 8]. More broadly, polyamine signaling intersects with immune regulation, as shown by the ability of the related polyamine spermine to target JAK signaling and restrain cytokine-mediated autoimmunity. Understanding GO:1904586 therefore informs stress biology, neurotoxicology, immunology and plant physiology.
• Putrescine catabolism is a metabolic response to several stresses in Escherichia coli, linking this GO term to bacterial stress survival.
• In plants, putrescine contributes to 4-aminobutyrate (GABA) production under abiotic stress, connecting polyamine response to stress metabolism.

• The process is conserved across kingdoms, making it a useful comparative framework for stress and metabolic research [2, 4, 7].
• CRISPR-based models enable causal testing of genes hypothesized to mediate the cellular response to putrescine.
What Happens During cellular response to putrescine?
Putrescine sensing and uptake
In simple terms: The cell first has to notice putrescine and, in some organisms, bring it inside.
The cellular response to putrescine begins with exposure of the cell to putrescine and, where relevant, its uptake or transport. In Leishmania infantum promastigotes, putrescine uptake is regulated in response to alpha-difluoromethylornithine treatment, showing that transport itself is a regulated part of the response to changes in polyamine availability. This step determines the intracellular putrescine pool that downstream effectors sense.
Metabolic remodeling and catabolism
In simple terms: The cell changes its metabolism, including breaking down putrescine, to cope with the new conditions.
A major output of the cellular response to putrescine is metabolic remodeling. In Escherichia coli, putrescine catabolism is a metabolic response to several stresses, indicating that the cell adjusts its metabolic pathways when putrescine is present or when stress changes polyamine pools. In plants, putrescine contributes to 4-aminobutyrate (GABA) production in response to abiotic stress, linking putrescine to a central stress metabolite.
Gene expression and signaling changes
In simple terms: The cell switches genes on or off and changes signaling to adapt.
The response includes changes in gene expression and signaling. In plants, putrescine is involved in freezing tolerance and cold acclimation by regulating abscisic acid levels in response to low temperature, which requires changes in gene expression and hormone signaling. In plant cell culture, exogenous putrescine regulates lignan biosynthesis through signaling pathways mediated by H2O2, showing that putrescine can act through redox signaling to alter biosynthetic gene programs.
Oxidative and glutathione-related responses
In simple terms: The cell manages oxidative stress that can accompany putrescine and polyamine metabolism.
Cellular responses to polyamine oxidation products involve glucose and glutathione, indicating that oxidative stress management is part of the broader cellular reaction to putrescine-related metabolites. This connects GO:1904586 to redox homeostasis and antioxidant defense.
Immune and intercellular consequences
In simple terms: Polyamine responses can change how cells talk to the immune system.
Polyamine signaling has immune consequences: cellular spermine targets JAK signaling to restrain cytokine-mediated autoimmunity, demonstrating that polyamine-related cellular responses can modulate immune signaling pathways. Although this study concerns spermine, it illustrates how the polyamine response network, of which putrescine is a part, can influence immune cell activity.

How Is cellular response to putrescine Regulated?
The cellular response to putrescine is regulated at multiple levels. Uptake can be adjusted in response to drugs that deplete polyamines, as shown in Leishmania infantum promastigotes treated with alpha-difluoromethylornithine. Catabolism is induced as part of stress responses in Escherichia coli, indicating transcriptional or metabolic regulation of putrescine-handling pathways. In plants, putrescine levels and effects are integrated with abscisic acid signaling during cold acclimation, providing hormonal regulation of the response. Redox signaling through H2O2 can mediate putrescine effects on biosynthetic pathways in plant cell culture. In mammals, polyamine-related signaling can intersect with JAK-STAT pathways, as shown for spermine-mediated restraint of cytokine signaling. Together, these layers allow cells to tune their response to putrescine according to metabolic state, stress and immune context.
cellular response to putrescine and Human Disease
| Gene | Disease / Biology | Potential Experimental Model |
|---|---|---|

Neurotoxicity and neurodegeneration
Putrescine has been used as an indicator of manganese neurotoxicity in human SH-SY5Y cells in a dose-response study, suggesting that the cellular response to putrescine is relevant to neurotoxic metal exposure and neuronal stress. Because polyamine oxidation products elicit cellular responses involving glucose and glutathione, oxidative stress pathways linked to putrescine may contribute to neuronal vulnerability.
Autoimmunity and immune regulation
Polyamine signaling can restrain cytokine-mediated autoimmunity, as demonstrated by cellular spermine targeting JAK signaling. This establishes a conceptual link between polyamine responses, including those involving putrescine, and immune-mediated disease, and supports investigating whether putrescine-responsive pathways modulate autoimmune inflammation.
Parasitic disease and drug response
In Leishmania infantum promastigotes, putrescine uptake is regulated in response to alpha-difluoromethylornithine treatment, a drug that targets polyamine biosynthesis. This links the cellular response to putrescine to antiparasitic drug efficacy and to the biology of Leishmania infection.
Plant stress and crop resilience
Although not a human disease, putrescine involvement in Arabidopsis freezing tolerance and cold acclimation through abscisic acid regulation illustrates how this response affects organismal stress resilience. Putrescine also contributes to GABA production under abiotic stress, which is relevant to crop stress physiology.

Transcriptomics and RNA-seq
RNA-seq can identify gene expression changes that occur as part of the cellular response to putrescine. This is appropriate because the GO definition explicitly includes gene expression changes, and because putrescine alters biosynthetic and stress-related gene programs in plant and bacterial systems [2, 4, 6].
Metabolomics and polyamine quantification
Measuring putrescine, spermine, spermidine and related metabolites such as GABA and glutathione provides a direct readout of the metabolic arm of the response. Such measurements have been used to link putrescine to GABA production in plants and to glutathione-related responses to polyamine oxidation products [2, 3].
Oxidative stress and redox assays
Because polyamine oxidation products elicit cellular responses involving glucose and glutathione, and because putrescine can act through H2O2-mediated signaling, redox assays such as glutathione quantification and ROS detection are informative for GO:1904586 [3, 6].
Cell viability and dose-response assays
Dose-response studies with putrescine or with neurotoxic metals can reveal how the cellular response to putrescine affects survival. Putrescine has been used as an indicator of manganese neurotoxicity in SH-SY5Y cells, demonstrating the utility of dose-response designs.
How CRISPR Can Be Used to Study GO:1904586 cellular response to putrescine
Knockout
CRISPR knockout of candidate genes such as ODC1, SAT1, SMOX or JAK1 allows researchers to test whether these genes are required for the cellular response to putrescine. For example, knocking out SMOX or SAT1 can reveal their contribution to oxidative and glutathione-related responses triggered by polyamine metabolism.
Point Mutation
Point-mutation knock-in can be used to test specific residues in transporters, enzymes or signaling proteins hypothesized to mediate putrescine sensing or downstream signaling. This is valuable when a candidate gene has a catalytic or regulatory site whose function must be dissected precisely.
Knock-in
Tagged knock-in of genes such as ODC1 or JAK1 enables visualization and biochemical isolation of the endogenous protein during the cellular response to putrescine, avoiding artifacts from overexpression. This supports localization and interaction studies in a physiologically relevant context.
Overexpression
Overexpression of polyamine enzymes or signaling components can test sufficiency: whether increased levels of a gene product amplify or alter the cellular response to putrescine. This complements knockout studies and can reveal gain-of-function effects relevant to stress or immune phenotypes [1, 4].
