Researchers can xenograft human cancer cells into zebrafish larvae, enabling real-time visualization of tumor progression and response to therapeutics. This approach accelerates the identification of anti-cancer compounds and the study of mechanisms underlying drug resistance. For example, zebrafish models have been instrumental in screening kinase inhibitors and immunotherapies, providing preclinical data that inform clinical trial design (National Cancer Institute).

In neurology, zebrafish are leveraged to investigate neurodevelopmental disorders, neurodegeneration, and epilepsy. Their conserved nervous system and behavioral repertoire allow for the assessment of drug effects on locomotion, cognition, and seizure activity. Zebrafish models of Parkinson’s, Alzheimer’s, and rare genetic epilepsies have facilitated the discovery of neuroprotective agents and anticonvulsants. The ability to perform large-scale behavioral assays in larvae enables rapid phenotypic screening, which is particularly valuable for identifying compounds that modulate neural circuits or synaptic function (National Institute of Neurological Disorders and Stroke).

Beyond oncology and neurology, zebrafish are increasingly used in cardiovascular research to study arrhythmias, heart regeneration, and drug-induced cardiotoxicity. Their transparent embryos allow for direct observation of heart structure and function, while genetic tools enable the modeling of human cardiac diseases. Zebrafish-based assays have contributed to the identification of novel anti-arrhythmic drugs and the evaluation of cardiac safety profiles for new chemical entities (American Heart Association).

Challenges and Limitations: Addressing Model Constraints

Zebrafish-based drug discovery has emerged as a powerful platform for high-throughput screening and in vivo modeling, yet several challenges and limitations persist that constrain its broader application. One primary concern is the evolutionary distance between zebrafish and humans, which can result in differences in drug metabolism, target engagement, and toxicity profiles. While zebrafish share a significant portion of their genome with humans, certain organ systems—such as the immune and hepatic systems—exhibit functional disparities that may limit the translational relevance of findings (European Bioinformatics Institute).

Another limitation is the developmental stage at which most assays are performed. Drug screening is typically conducted on zebrafish embryos or larvae, which lack fully developed organs and mature physiological systems. This can obscure the detection of adverse effects or pharmacokinetic properties that would only manifest in adult organisms. Additionally, the small size and transparency of zebrafish, while advantageous for imaging and throughput, can complicate the administration of precise drug dosages and the assessment of tissue-specific responses (Zebrafish Information Network).

Genetic variability and strain differences also pose challenges. Laboratory zebrafish lines may not fully capture the genetic diversity found in human populations, potentially limiting the generalizability of results. Furthermore, the availability of validated antibodies and molecular tools for zebrafish lags behind those for mammalian models, restricting the depth of mechanistic studies and biomarker discovery (Addgene).

Regulatory acceptance remains another hurdle. While zebrafish models are increasingly recognized for early-stage screening, regulatory agencies such as the U.S. Food and Drug Administration and European Medicines Agency still require confirmatory studies in mammalian systems before clinical translation. This necessitates additional resources and time, potentially offsetting some of the efficiency gains offered by zebrafish-based approaches.

Addressing these constraints will require continued investment in comparative genomics, the development of adult zebrafish models, improved molecular toolkits, and closer alignment with regulatory standards. Collaborative efforts between academia, industry, and regulatory bodies are essential to fully realize the potential of zebrafish in drug discovery pipelines.
