Figure 2. SHARP, LBR, and SAF-A are required for Xist-mediated gene silencing.
(a) Screen for Xist-mediated gene silencing for knockdown of control (top), non-silencing proteins (middle), or silencing proteins (bottom). (b) Gpc4 mRNA levels after induction of Xist (+dox) normalized to Gpc4 levels before Xist induction (−dox). Error bars: standard error of the mean across 50 cells from one experiment. siCtrl: scrambled siRNA control. (c) Images of individual cells for two X-linked mRNAs, Gpc4 (green) and Atrx (red), and DAPI (blue) after treatment with different siRNAs (rows). The number of identified mRNAs is shown. Scale bars, 5 micrometers.
