The zebrafish, Danio rerio, has been an important animal model for cancer research over the last decade. The capability of a high-throughput screen in zebrafish and a wide range of pharmacologically active compounds elicit physiological responses in zebrafish embryos comparable to those in mammalian systems, making zebrafish ideal for identifying clinically relevant drug targets and compounds that regulate tumor progression. The zebrafish model is suitable for patient-derived xenograft (pdx) and large-scale screening of lead compounds against specific malignancies. This established vertebrate model has many advantages, including fast response time, cost efficiency for drug testing, efficient manipulation of the host microenvironment by genetic tools, suitable for small molecule drug screening in high-throughput setting, easy maintenance, transparency for easy observation, high fecundity, and rapid generation time. The zebrafish model is a good alternative in vivo model to mammals for robust testing of drug candidates for cancer therapy.
