(B) Relative Quantitative Real-Time PCR analysis of MCOLN1, ATP6V1C1, HEXA and UVRAG mRNA transcript levels in ARPE-19 cells depleted of TFEB and TFE3 upon incubation with DMSO (Control) or Tunicamycin (5 µg/ml) for 16 h (mean ± SD of the RNA fold change of indicated gene mRNAs normalized to actin mRNA from three independent experiments, one-way ANOVA analysis versus the same treatment condition in the siNon-Target (siNT) treated cells or versus the DMSO condition in siNon-Target (siNT) treated cells, *p < 0.05, **p < 0.01, ***p < 0.001).
