(A) Hierarchical clustering of significantly differentially expressed genes (adjusted p-value <0.05) 96 hr following knockout of USP8, UBAP1, HGS, and PTPN23 in MDAMB231 cells. (B) Gene sets significantly enriched (FDR <0.05) in MDAMB231 cells 96 hr after knockout of USP8, UBAP1, HGS, (cont.) and PTPN23. The top five upregulated and top five downregulated gene sets for each condition are shown. (C) Quantification of immunofluorescence measuring p21 levels following 24 hr treatments with XL177A or nutlin3a at the concentrations indicated in MCF7 wt and p53 knock down cells.
