TERT and brain neoplasm: To investigate the biological pathways altered between ALT and Telomerase+ brain tumors, we first identified the human orthologs of the zebrafish DE genes (RAS-Tert vs. RAS) using Biomart and Beagle and then performed pathways enrichment analysis using Reactome with the significantly enriched pathways having adjusted p-value (padj) < 0.1 (see Table S2).
