ARGLU1 was identified in a screen for new modulators of glucocorticoid signaling in the CNS. RNA-seq of neuronal cells ±siARGLU1 revealed significant changes in the expression and alternative splicing of distinct genes involved in neurogenesis. Treatment with dexamethasone, a GR activator, also induced changes in the pattern of alternatively spliced genes, highlighting an underappreciated global mechanism of glucocorticoid action in neuronal cells. Thus, in addition to its basal role, ARGLU1 links glucocorticoid-mediated transcription and alternative splicing in neural cells, providing new avenues from which to investigate the molecular underpinnings of cognitive stress disorders. Overall design: N2a cells were transfected with non-targeting control and ARGLU1 siRNAs for 48 hrs followed by Vehicle (EtOH) or 100 nM Dexamethasone treatment for 4 hrs. RNA was extracted and pooled by treatment group (n=3/group) and mRNA enriched Illumina TruSeq V2 RNA libraries were prepared. Samples were sequenced on Illumina HiSeq2500. Less...
