• To showcase the identification of novel cancer biology and conserved molecular pathways.
• To demonstrate the application of these tools in drug discovery and assay validation.

Main Methods:

• Transcriptomic analyses using DNA microarray and RNA sequencing platforms.
• Application of these genomic tools in various zebrafish cancer models.

Main Results:

• Identification of common molecular pathways in hepatocellular carcinoma, intrahepatic cholangiocarcinoma, melanoma, ERMS, T-ALL, Ewing's sarcoma, and glioma.
• Demonstration of high similarity and conservation of molecular pathways between zebrafish models and human cancers.
• Successful development and validation of chemical compound screening assays.

Conclusions:
