RNA-Seq based differential gene expression analysis of tumours arising in Rosa26_Alkal2;Th-MYCN (Alkal2) [n=6], Alk-F1178S;Th-MYCN (AlkF1174S) [n=6] and Th-MYCN (MYCN) mice [n=4]. See Table S4 for detailed results. A. Read coverage of the codon-optimised Alkal2 transgene, confirming Alkal2 expression in Alkal2 tumours.
