ASCL1 and neuroblastoma: To compare the transcriptome-wide effects of ectopic WT and S-A ASCL1 on gene expression, we performed principal component analysis (PCA) on RNA-seq data of NB cells expressing uninduced levels of ASCL1, in comparison to cells ectopically expressing doxycycline-induced WT or S-A ASCL1 for 24 h.
