C Relative UPP1 mRNA expression levels in HCT116 cells either transfected with control (siCtrl) or combined TFE3- and MITF- targeting (siTFE3/siMITF) siRNAs and treated as indicated (NEN (N) 1.2 µM, Domperidone (D) 30 µM, ISRIB 1 µM), determined by qPCR. Data information: data (N=3) are presented as mean (SD) and were analyzed by two -way ANOVA with Tukey post-hoc test
