RNA-seq analysis dataset: Hippocampal tissues from Emx1-Cre;Auts2-flox/flox and Auts2-flox/flox mice at P14

Previous studies have revealed that AUTS2 regulates cytoskeletal organization as well as gene expression during prenatal brain development. Its involvement in controlling synapses, however, remains unclear. Here, we report the increased dendritic spine formation in Auts2 mutant mice as well as the primary cultured neurons from Auts2 mutant mice. To investigate the involvement of AUTS2 function in the regulation of gene expression, we performed transcriptome analysis. RNA-seq on total RNA from the hippocampal tissues of Emx1Cre/+;Auts2flox/flox homozygous conditional KO mice at P14 reveals changes in gene associated with brain development including synapse formation. These results suggest that AUTS2 regulates the expression of genes that are related to synapse formation/function, and some of which may be involved in spine number restriction. Aberrant expression of such synaptic genes may cause synaptic dysfunction in patients with AUTS2 mutations. Overall design: The mRNA profiles of the hippocampal tissues from four Emx1-Cre;Auts2-flox/flox homozygous mutant mice and four Auts2-flox/flox control mice at P14 were generated using the Illumina HiSeq platforms.
