Zebrafish Endocrine & Metabolic Toxicity

Background

Zebrafish-based endocrine and metabolic toxicity assessment provides an efficient in vivo platform for evaluating the effects of test substances on hormone regulation, thyroid function, metabolic homeostasis, energy balance, and growth-related physiological processes.

Endocrine disruption and metabolic toxicity are major concerns in drug safety evaluation, environmental toxicology, and consumer product safety assessment. Test substances may interfere with hormone biosynthesis, hormone receptor signaling, thyroid hormone pathways, steroid hormone signaling, glucose homeostasis, lipid metabolism, mitochondrial function, or energy utilization, leading to developmental, reproductive, neurological, and metabolic dysfunction.

Zebrafish are widely used for endocrine and metabolic toxicity studies because they share highly conserved endocrine and metabolic pathways with mammals, including thyroid hormone signaling, reproductive hormone regulation, insulin signaling, lipid metabolism, and energy homeostasis. Their transparent embryos, rapid development, low test article requirements, and compatibility with imaging-based and high-throughput assays make zebrafish an ideal model for the early detection of endocrine-disrupting chemicals (EDCs) and metabolic toxicants.

This service is suitable for safety assessment of:

Small molecules and drug candidates
Environmental endocrine-disrupting chemicals (EDCs)
Industrial chemicals and pesticides
Nanomaterials
Natural products and functional ingredients
Cosmetic and consumer product ingredients

Our zebrafish endocrine and metabolic toxicity assays integrate developmental assessments, phenotypic analysis, imaging-based endpoints, behavioral evaluation, and optional molecular readouts to support early toxicity screening, mechanistic studies, candidate optimization, and safety risk assessment.

Our Zebrafish Endocrine & Metabolic Toxicity Services

Zebrafish Endocrine Toxicity Assays

Evaluate whether test substances interfere with hormone-regulated development and physiological functions. These assays enable the identification of potential endocrine-disrupting effects associated with growth, reproduction, stress responses, thyroid hormone signaling, and hormone-associated gene expression.

Thyroid Disruption Assay

Evaluate the potential of test compounds to disrupt thyroid function and thyroid hormone-regulated biological processes in zebrafish. Endpoints include thyroid gland development, thyroid hormone signaling activity, larval growth, pigmentation, developmental progression, and thyroid-responsive biomarkers.

Metabolic Disruption Assay

Evaluate the effects of test compounds on metabolic homeostasis, including energy metabolism, lipid accumulation, glucose homeostasis, yolk utilization, feeding behavior, and locomotor activity. This assay is suitable for identifying metabolic toxicants, detecting obesogenic effects, and assessing metabolism-related safety risks.

Applications

Zebrafish endocrine and metabolic toxicity assessment can be applied to:

Early safety screening of drug candidates
Identification of endocrine-disrupting chemicals
Thyroid disruption risk assessment
Metabolic toxicity evaluation
Environmental chemical and pollutant testing
Pesticide and industrial chemical safety assessment
Natural product and functional food ingredient evaluation
Cosmetic raw material safety screening
Mechanistic studies of hormone and metabolism-related toxicity
