Description
GO:0010566, regulation of ketone biosynthetic process, is a biological process Gene Ontology term that encompasses any mechanism controlling the rate, frequency, or extent of ketone formation within individual cells. Ketone bodies, primarily acetoacetate, beta-hydroxybutyrate (BHB), and acetone, are small lipid-derived molecules synthesized predominantly in the liver during low carbohydrate availability, and they serve as alternative fuels for extrahepatic tissues such as the heart and brain. Because ketone levels influence systemic energy homeostasis and cell signaling, their biosynthesis is tightly regulated. This term is therefore central to understanding metabolic flexibility in health and disease. The regulation of ketone biosynthesis intersects with mitochondrial metabolism, post-translational modifications, and nutrient-sensing pathways [2,3,5]. For example, the activity of ketolytic enzymes such as OXCT1 is modulated by succinylation, linking ketone metabolism to mitochondrial acyl-CoA pools. Sirtuin 5 (SIRT5) removes succinyl groups from mitochondrial proteins, thereby influencing metabolic networks that include ketone body utilization. In addition, BHB itself can act as a signaling molecule, for instance by promoting mitochondrial-derived vesicle biogenesis or by modifying STAT1 to suppress M1 macrophage polarization. These findings highlight that regulation of ketone biosynthesis is not merely a metabolic endpoint but a node integrating cellular stress responses, epigenetic regulation, and immune function. Researchers study GO:0010566 to dissect how cells switch between glucose and ketone metabolism, and to identify therapeutic vulnerabilities in cancer, heart disease, and metabolic disorders [2,4,8].

What Is GO:0010566?
According to the Gene Ontology, GO:0010566 (regulation of ketone biosynthetic process) is defined as any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of a ketone, carried out by individual cells. In simpler terms, it covers all cellular mechanisms that turn ketone production up or down, including changes in enzyme activity, gene expression, and substrate availability.
Why Is regulation of ketone biosynthetic process Important in Cell Biology?
Regulation of ketone biosynthesis is critical because ketone bodies are not only alternative fuels but also potent signaling molecules that affect mitochondrial function, inflammation, and tumor growth [1,2,7,8]. Understanding how cells control ketone production can reveal therapeutic strategies for heart failure, cancer, and metabolic diseases, where ketone metabolism is often reprogrammed [2,3,4,8].
• Ketone bodies provide energy during fasting and exercise, and their production must be finely tuned to avoid ketoacidosis.
• BHB, a major ketone, regulates mitochondrial-derived vesicle biogenesis and improves mitochondrial functions.
• Ketone metabolism is reprogrammed in cancer, where OXCT1 succinylation promotes ketolysis and liver tumor growth.
• Modulating ketone body metabolism with empagliflozin improves mitochondrial dysfunction in diabetic cardiomyopathy.
• SIRT5-dependent desuccinylation regulates mitochondrial metabolic networks, including ketone-related pathways.
• BHB suppresses M1 macrophage polarization via STAT1 beta-hydroxybutyrylation, linking ketone regulation to immunity.
• Induction of a metabolic switch from glucose to ketone metabolism creates therapeutic vulnerability in lung cancer.
• Ketone regulation is relevant to ferroptosis, as imidazole ketone erastin induces ferroptosis and slows tumor growth.
• Understanding GO:0010566 aids in developing dietary and pharmacological interventions targeting ketosis [2,8].
• CRISPR screens can identify novel regulators of ketone biosynthesis and utilization.
What Happens During regulation of ketone biosynthetic process?
Initiation of ketogenesis in mitochondria
In simple terms: Ketone production starts in liver mitochondria when fatty acids are broken down.
Ketogenesis begins with the condensation of two acetyl-CoA molecules to form acetoacetyl-CoA, which is then converted to HMG-CoA and finally to acetoacetate, the parent ketone body. This process occurs primarily in the mitochondrial matrix of hepatocytes and is stimulated by low glucose and high fatty acid oxidation. The regulation of this step involves nutrient-sensing pathways and the availability of acetyl-CoA, which is influenced by the overall metabolic state of the cell.
Enzymatic control by succinylation and desuccinylation
In simple terms: Chemical tags on enzymes can turn ketone metabolism up or down.
The activity of ketolytic and ketogenic enzymes is modulated by post-translational modifications such as succinylation. For instance, OXCT1, a key enzyme in ketone utilization, is activated by succinylation mediated by SUCLA2, and this modification promotes ketolysis and liver tumor growth. Conversely, the mitochondrial desuccinylase SIRT5 removes succinyl groups from metabolic enzymes, thereby regulating mitochondrial metabolic networks that include ketone body pathways. This dynamic modification provides a layer of regulation for GO:0010566.
Signaling roles of beta-hydroxybutyrate
In simple terms: Ketone bodies can act as signals, not just fuel.
Beta-hydroxybutyrate (BHB) is not only an energy carrier but also a signaling molecule. It facilitates mitochondrial-derived vesicle biogenesis and improves mitochondrial functions, which can feedback on cellular metabolism. Additionally, BHB can modify proteins through beta-hydroxybutyrylation; for example, it suppresses M1 macrophage polarization by modifying STAT1. These signaling actions indirectly influence the regulation of ketone biosynthesis by altering cellular demand and metabolic state.
Integration with glucose and fatty acid metabolism
In simple terms: Ketone production is tied to how cells use sugar and fat.
The regulation of ketone biosynthesis is intimately linked to glucose and fatty acid metabolism. A metabolic switch from glucose to ketone metabolism can be induced in cancer cells, creating therapeutic vulnerabilities. In the heart, ketone bodies are important fuels, and their metabolism is altered in heart failure and diabetic cardiomyopathy [2,4]. Thus, GO:0010566 encompasses the crosstalk between multiple metabolic pathways.
Pharmacological and dietary modulation
In simple terms: Drugs and diet can change how many ketones cells make.
Ketone biosynthesis can be modulated by pharmacological agents such as empagliflozin, which improves mitochondrial dysfunction in diabetic cardiomyopathy by modulating ketone body metabolism and oxidative stress. Ketogenic diets can also induce a metabolic switch that affects tumor growth. These interventions highlight the translational relevance of understanding the regulation of ketone biosynthesis.

How Is regulation of ketone biosynthetic process Regulated?
The regulation of ketone biosynthesis is controlled by nutrient availability, hormonal signals, and post-translational modifications. Insulin suppresses ketogenesis, while glucagon and fasting promote it. At the molecular level, succinylation and desuccinylation of enzymes such as OXCT1 and SIRT5 provide dynamic control [3,5]. Additionally, beta-hydroxybutyrate can act as a signaling molecule to modulate immune and mitochondrial functions, creating feedback loops [1,7]. Pharmacological agents like empagliflozin can also influence ketone body metabolism.

Heart failure and diabetic cardiomyopathy
Ketone bodies are important fuels for the heart, and their metabolism is altered in heart failure and diabetic cardiomyopathy. Empagliflozin improves mitochondrial dysfunction in diabetic cardiomyopathy by modulating ketone body metabolism and oxidative stress. Thus, regulation of ketone biosynthesis is a potential therapeutic target in cardiac disease [2,4].
Cancer metabolism
Cancer cells can reprogram ketone metabolism to support growth. OXCT1 succinylation and activation by SUCLA2 promotes ketolysis and liver tumor growth. Induction of a metabolic switch from glucose to ketone metabolism programs ketogenic diet-induced therapeutic vulnerability in lung cancer. These findings suggest that targeting ketone regulation could be a strategy for cancer therapy [3,8].
Inflammation and immune regulation
Beta-hydroxybutyrate suppresses M1 macrophage polarization through beta-hydroxybutyrylation of STAT1, linking ketone metabolism to immune responses. This implies that regulating ketone biosynthesis could influence inflammatory diseases.
Ferroptosis and oxidative stress
Imidazole ketone erastin induces ferroptosis and slows tumor growth in a mouse lymphoma model, indicating a connection between ketone-related compounds and cell death pathways. Additionally, BHB facilitates mitochondrial-derived vesicle biogenesis and improves mitochondrial functions, which may protect against oxidative stress.
