Dyrk1a dosage effects on the transcriptome of embryonic hearts from the Dp1Tyb mouse model of Down syndrome using bulk RNAseq. Dyrk1a dosage effects on the transcriptome of embryonic hearts from the Dp1Tyb mouse model of Down syndrome using bulk RNAseq

We performed bulk RNAseq on whole hearts from E13.5 Dp1Tyb embryos and from wild-type littermates, as well as hearts from E13.5 Dp1TybDyrk1a+/+/- embryos and wild-type littermates. Analysis showed the expected increased expression of the Hsa21-orthologous genes on Mmu16 that are present in 3 copies. Gene set enrichment analysis identified pathways that are altered in Dp1Tyb hearts. Some of these changes were dependent on 3 copies of Dyrk1a. Overall design: RNAseq on 5 E13.5 Dp1Tyb embryonic hearts and 5 wild-type littermate embryonic hearts, and on 5 E13.5 Dp1TybDyrk1a+/+/- embryonic hearts and 5 wild-type littermate embryonic hearts.
