Effects of Ars2 or DGCR8 siRNA on gene expression

Ars2 is a component of the nuclear cap-binding complex that is required for cellular proliferation and contributes to microRNA biogenesis. Arrays were performed to determine the repertoire of genes that change following knock-down of Ars2. Knock-down of DGCR8 was also performed to determine which changes in Ars2 knock-down cells resulted from defects in microRNA expression. 9 samples were analyzed including: three biological replicates of control siRNA-transfected HeLa cells, HeLa cells transfected with three independent siRNAs targeting Ars2, or HeLa cells transfected with three independent siRNAs targeting DGCR8.
