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...

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.
FAQs
Exposure duration is central because the model is designed to capture immediate responses to elevated glucose rather than changes that accumulate during prolonged metabolic disease. Researchers can therefore relate observed developmental, cellular, or signaling changes to a defined short-term window. This distinction helps separate rapid glucose-sensitive effects from consequences requiring sustained disease-like conditions.
Growth patterns, cell behavior, and molecular signaling provide complementary evidence of glucose sensitivity. Developmental changes show effects at the organism or tissue level, cellular measurements indicate altered behavior within the exposed system, and signaling results help connect those outcomes to underlying biological responses. Examining these levels together strengthens interpretation of developmental effects.
Defined high-glucose conditions make the exposure controlled and interpretable. When researchers specify the glucose environment and exposure period, they can compare developmental, cellular, or molecular outcomes against the conditions used in the experiment. This control supports clearer links between excess sugar and observed changes, rather than attributing results broadly to an unspecified metabolic state.
A general workflow begins by selecting an embryo, cell population, or tissue, then exposing it to a defined high-glucose condition for a controlled period. Researchers subsequently assess development, cell behavior, and molecular signaling. Comparing these readouts with the experimental exposure allows the study to identify short-term responses associated with abnormal glucose conditions.
Researchers choose an acute hyperglycemia model when they need to isolate short-term effects of elevated glucose. It is useful for asking whether abnormal exposure can produce an immediate developmental or molecular response without incorporating changes that arise during prolonged metabolic disease. This makes the approach relevant to early investigations of diabetes-associated developmental complications.
The model can support studies of embryonic growth, glucose-sensitive developmental defects, and the cellular or molecular responses associated with diabetes-related developmental complications. Researchers may use embryos, cells, or tissues depending on the question. Outcomes from these systems can help connect excess glucose exposure with altered development and identify mechanisms for further investigation.
