Chordoma is a rare aggressive tumor arising from transformed notochord remnants. Various potentially oncogenic factors have been found deregulated in chordoma and its metastases yet clear causation remains uncertain. In particular expression of the notochord controlling transcription factor Brachyury is hypothesized as key molecular driver in chordoma formation yet an in vivo model to causally test its oncogenic potential in the notochord is missing. Here we apply a zebrafish model of chordoma onset to identify the notochord transforming potential of tumor implicated candidate genes in vivo. We find that overexpression of human and zebrafish Brachyury including a version with augmented transcriptional activity is insufficient to initiate notochord hyperplasia in vivo. In contrast the repeatedly chordoma implicated receptor tyrosine kinase RTK genes EGFR and KDR/VEGFR2 are sufficient to transform developmental notochord cells akin to direct activation of Ras. Analysis of transcriptome and sub cellular organization from transformed notochords suggests that aberrant activation of RTK/Ras signaling attenuates processes required for the differentiation of notochord cells. Taken together our results provide first in vivo indication for a lack of tumor initiating potential of Brachyury expression in the notochord and suggest activated RTK signaling as potent hyperplasia initiating event in chordoma. | ENA FIRST PUBLIC:2018 12 01|ENA LAST UPDATE:2018 10 30 | Protocols: 8 dpf wildtype and Tgtwhh:Gal4;TgUAS:EGFP HRASV12 were euthanized with 3% Tricaine methanesulfonate Sigma. Embryos were decapitated and incubated in Tripsin EDTA Sigma for 30 minutes to facilitate tissue dissociation. Notochords were then dissected using tungsten needles and immediately transferred to Trizol LS Ambion. We isolated 30 50 notochords per replicate with a total of 3 replicates per condition 3x wildtype 3x HRASV12. Notochord RNA was extracted following the manufacturer's protocol using Trizol LS. RNA seq libraries were constructed using the Truseq stranded total RNA kit. | HRASC | SAMEA5055149 | UZH | ENA FIRST PUBLIC:2018 12 01T17:03:21Z|ENA LAST UPDATE:2018 10 30T13:30:13Z|External Id:SAMEA5055149|INSDC center name:UZH|INSDC first public:2018 12 01T17:03:21Z|INSDC last update:2018 10 30T13:30:13Z|INSDC status:public|Submitter Id:E MTAB 7349:HRASC|age:8|broker name:ArrayExpress|common name:zebrafish|developmental stage:embryo|genotype:Tgtwhh:Gal4;TgUAS:EGFP HRASV12|individual:mixed pool of 30 to 50 embryos|organism part:notochord|sample name:E MTAB 7349:HRASC|scientific name:Danio rerio|sex:mixed | Illumina HiSeq 2500 paired end sequencing; Receptor Tyrosine Kinase pathway activation is sufficient to trigger chordoma in zebrafish | E MTAB 7349:HRASC p | HRASC p | Receptor Tyrosine Kinase pathway activation is sufficient to trigger chordoma in zebrafish | 8 dpf wildtype and Tgtwhh:Gal4;TgUAS:EGFP HRASV12 were euthanized with 3% Tricaine methanesulfonate Sigma.
