Reduced TRPS1 expression increases interferon signaling thereby affecting normal function of HC11 cells. (A) Heatmap reflecting gene expression at the genes listed in the interferon alpha and interferon gamma gene lists from the Hallmark Gene Sets collection shown in Figure 3D, with all genes annotated. (B) Western blot analysis of STAT1 and STAT2 expression levels in HC11 control and TRPS1 knockout clones. β-actin was used as a loading control. (C) Western blot analysis of phosphorylated and total STAT5 levels in HC11 control and TRPS1 knockout cells transduced with a non- targeting shRNA or a pool of shRNAs targeting Stat1 in full medium or upon treatment with DIP mix. β- actin was used as a loading control. (D) Western blot analysis of phosphorylated and total STAT5 levels in IFNγ (30ng/ml) treated HC11 cells in full medium or upon treatment with DIP mix. β-actin was used as a loading control. (E,F) RT-qPCR analysis of Stat1 (E) and β-casein (Csn2) (F) expression levels upon treatment with DIP mix and/or IFNγ (30ng/ml). Data represent mean+SD, n=2. T-test: *** p<0.001, ** p<0.01. (G) Western blot analysis of phosphorylated and total STAT1 expression levels in HC11 control and TRPS1 knockout cells upon treatment with IFNγ (30ng/ml). β-actin was used as a loading control. (H) Pathway enrichment analysis performed on RNA-seq of HC11 cells treated with or without TSA (300nM), using the MSigDB Hallmark GeneSet Collection (Liberzon et al. 2015). FDR<0.05 was considered significant. The interferon signaling pathways are highlighted in green. (I) Western blot analysis of STAT1 and STAT2 expression levels in HC11 cells treated with or without TSA (300nM). β-actin was used as a loading control. 5 .
