Purpose: The goal of this study was to assess gene expression changes in neurons overexpressing SOX5 using human primary neuronal culture system. Methods: 6 samples each from control GFP and SOX5 overexpressing neurons were used to isolate total RNA using miRNeasy kit, Qiagen.  We performed rRNA-depleted 69bp paired end stranded RNA-seq on neurons overexpressing either GFP or SOX5 tagged with GFP. Overexpression of SOX5 in neurons validated that a significant proportion of Attenuated cortical patterning (ACP) genes are regulated by SOX5, and that predicted SOX5 targets exhibit a net downregulation, consist with its repressive function. This supports the prediction that attenuated patterning of SOX5 between cortical regions contributes to direct alterations in SOX5 targets and likely to indirect alterations in SOX5 non-targets in the ACP set. delpleted 69 bp stranded RNA-seq in SOURCE: Vivek Swarup (swarup@ucla.edu) - Geschwind Lab University of California at Los Angeles
