Metabolic memory is the phenomenon by which diabetic complications persist and progress unimpeded even after euglycemia is achieved pharmaceutically. Here we describe a diabetes mellitus zebrafish model which is unique in that it allows for the examination of the mitotically transmissible epigenetic components of metabolic memory in vivo.

Hyperosmolar Hyperglycemic State, or HHS, is a serious and life-threatening complication of type 2 diabetes mellitus. It is characterized by three main features: severe hyperglycemia, profound dehydration, and elevated serum osmolality, all occurring without significant ketoacidosis.HHS typically develops in older adults or individuals with limited access to fluids. This may result from illness, cognitive impairment, or medications such as diuretics or corticosteroids. These factors reduce...

Renal injuries incurred from nephrotoxins, which include drugs ranging from antibiotics to chemotherapeutics, can result in complex disorders whose pathogenesis remains incompletely understood. This protocol demonstrates how zebrafish can be used for disease modeling of these conditions, which can be applied to the identification of renoprotective measures.

This work describes methods to establish acute and chronic hyperglycemia models in zebrafish. The aim is to investigate the impact of hyperglycemia on physiological processes, such as constitutive and injury-induced neurogenesis. The work also highlights the use of zebrafish to follow radiolabeled molecules (here, [18F]-FDG) using PET/CT.

All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Zebrafish (Danio rerio) are widely used as an alternative vertebrate model organism in biomedical research. Their genetic similarity to humans, rapid development, and suitability for large-scale studies make them valuable tools...
FAQs
Elevated glucose can disturb both metabolic and neuronal homeostasis, creating conditions in which nervous system function no longer supports typical behavioral patterns. These disturbances may appear as changes in movement, overall activity, social interaction, or responses to environmental stimuli. Measuring several behavioral domains helps connect glucose dysregulation with distinct functional consequences rather than relying on a single endpoint.
Locomotion and activity patterns provide indicators of altered movement or general behavioral state, while social interaction assays examine changes in interaction with other fish. Responses to environmental stimuli add a context-dependent measure of behavior. Considering these endpoints together can reveal whether hyperglycemia produces a broad behavioral phenotype or affects particular aspects of behavioral function.
Zebrafish allow researchers to examine glucose-related behavioral effects in an organism that is small, genetically tractable, and suitable for standardized behavioral assays. This combination supports efficient comparisons among behavioral phenotypes and makes it possible to relate observable changes to underlying physiology. The approach is especially useful when investigators need coordinated behavioral and biological measurements.
A behavioral assessment should examine multiple domains rather than interpreting one altered measure in isolation. Locomotion and activity patterns address general movement, whereas social interaction and environmental responses probe more specific behavioral functions. Comparing results across these domains helps determine whether hyperglycemia is associated with a broad reduction or increase in behavior or with a selective change.
Researchers first establish elevated blood glucose in the zebrafish, then apply standardized behavioral assays to measure selected outcomes such as locomotion, activity, social interaction, or environmental responses. The resulting phenotypes can be compared across experimental conditions, followed by evaluation of candidate interventions. Behavioral findings may then be related to metabolic and nervous system physiology.
Standardized assays provide a consistent way to measure behavioral outcomes across experimental conditions. Consistency is important when researchers compare locomotion, activity patterns, social interaction, or responses to environmental stimuli and when they evaluate candidate interventions. It also improves the ability to identify reproducible behavioral phenotypes associated with impaired glucose regulation rather than changes caused by inconsistent assessment.
Researchers can use the model after establishing a measurable behavioral phenotype associated with elevated glucose. Candidate interventions can then be assessed by determining whether locomotion, activity patterns, social interaction, or environmental responses differ after treatment or another experimental manipulation. This design helps connect intervention-related behavioral changes with the broader consequences of altered glucose regulation.
Behavioral findings can provide functional evidence that altered glucose metabolism is linked to nervous system consequences. Changes in movement, activity, social interaction, or environmental responses may be considered alongside metabolic observations to identify relationships between glucose regulation and neuronal homeostasis. In this context, behavior serves as an outcome through which researchers can investigate diabetes-associated biological effects.
