Thus  there is great need to dissect the driving mechanisms for UM  and develop strategies to evaluate potential therapeutics. Using a zebrafish model  we previously identified MITF  the master melanocyte transcription factor  as a tumor suppressor in GNAQQ209L driven UM. Here  we show that zebrafish mitfa deficient GNAQQ209L driven tumors significantly up regulate neural crest markers  and higher expression of a melanoma associated neural crest signature correlates with poor UM patient survival. We further determined how the mitfa null state  as well as expression of GNAQQ209L  YAPS127A;S381A  or BRAFV600E oncogenes  impacts melanocyte lineage cells before they acquire the transformed state. Specifically  examination 5 dpf showed that mitfa deficiency is sufficient to upregulate pigment progenitor and neural crest markers  while GNAQQ209L expression promotes a proliferative phenotype that is further enhanced by YAPS127A;S381A co expression. Finally  we show that this oncogene induced proliferative phenotype can be used to screen chemical inhibitors for their efficacy against the UM pathway. Overall  this study establishes that a neural crest signature correlates with poor UM survival  and describes an in vivo assay for pre clinical trials of potential UM therapeutics.
