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.

Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...

FAQs
Duration determines whether cells and developing tissues experience an immediate glucose response or a sustained metabolic disturbance. Prolonged exposure allows glucose-dependent changes in metabolism, cellular signaling, oxidative stress, and inflammatory responses to develop progressively. This makes exposure time an important experimental variable when interpreting whether observed effects reflect early signaling changes or broader developmental consequences.
Sustained hyperglycemia can affect cell proliferation, differentiation, tissue patterning, and organ formation. These processes are interconnected, so altered signaling or metabolism in one developmental population may influence later tissue organization. In developmental biology, examining these outcomes helps connect abnormal glucose conditions with changes in how embryonic cells acquire identities and assemble into functional structures.
They provide mechanistic links between elevated glucose exposure and developmental effects. A Chronic Hyperglycemia Model can reveal whether prolonged glucose imbalance coincides with changes in oxidative stress, inflammatory responses, or related cellular signaling. Studying these features alongside developmental outcomes helps researchers move beyond describing abnormal tissue formation and identify molecular processes that may contribute to it.
The essential procedure is to maintain cells, tissues, or developing organisms under elevated glucose conditions for a defined period. Researchers then examine glucose-dependent responses as exposure continues, focusing on metabolic changes, signaling, oxidative stress, inflammation, and developmental features. The design should keep the exposure sustained enough for prolonged effects to emerge rather than measuring only an immediate response.
Measurements may span several biological levels, including cellular behavior, tissue organization, and organ formation. In developmental applications, researchers can assess changes in proliferation, differentiation, and patterning while also examining associated metabolic or signaling responses. This combination connects molecular changes with visible developmental outcomes and helps determine how broadly sustained glucose imbalance affects early development.
They are useful when researchers need to examine how maternal or embryonic hyperglycemia may influence early developmental events. The models support investigation of pathways associated with abnormal development and provide a framework for evaluating potential interventions. Their value lies in linking prolonged metabolic imbalance with developmental abnormalities while preserving attention to cellular, tissue, and organ-level consequences.
