Figure 5. GSK-3β inhibition alters extrinsic apoptosis genes.
A) Volcano plot of KEGG apoptosis genes derived from RNA-Seq data on Ramos cells treated for 3 hours with 3 μM CHIR99021 in biological triplicates. Key apoptotic genes are labeled, with genes in blue being down-regulated, genes in red being up-regulated, and genes in green having no significant changes. B) qRT-PCR expression analysis for known Myc-dependent intrinsic/mitochondrial apoptotic factors was performed on Ramos cells treated for 2 hours with DMSO (blue bars) or 3 μM CHIR99021 (red bars) followed by a 6 hour time course of .25 μM doxorubicin. C) qRT-PCR expression analysis for extrinsic apoptosis factors was performed on Ramos cells treated as in B). Notable changes are indicated with yellow arrows.
