Genome-wide transcriptomic analysis of the forebrain of postnatal Slc13a4+/- mice.

We performed an RNA transcriptomic based sequencing screen on the whole forebrain from Slc13a4+/- and Slc13a4+/+mice at P20. Differential expression analysis revealed 90 differentially regulated genes in the forebrain of Slc13a4+/- mice (a p-value of 0.1 was considered as significant). Of these, 55 were upregulated, and 35 were downregulated in the forebrain of heterozygous mice. Moreover, when we stratified further with a ± 1.2 fold-change, we observed 38 upregulated, and 16 downregulated genes in the forebrain of heterozygous mice. This resource provides a useful tool to interrogate which pathways may require elevated sulfate levels to drive normal postnatal development of the brain.
