B Immunofluorescence (IF) of HCT116 cells treated with DMSO (Control (Ctrl)), NEN, Domperidone (Domp) or NEN+Domp as indicated (NEN, 1.2 µM; Domp, 30 µM) for 16 h and stained with anti-Lamp1 (top panel), Alexa-555 LC3 (middle panel) co-stained with Alexa-647 p62 (bottom panel). Nuclei, Blue (dapi). Scale bar 20 µm. Mean (SEM) fluorescence of Lamp1 (Ctrl, NEN, Domp (N=20 cells); NEN+Domp (N=24 cells)), LC3-II (Ctrl, NEN+Domp (N=16 cells)); NEN, Domp (N=16 cells)) or P62 (Ctrl (N=38 cells); NEN (N=27 cells); Domp (N=28 cells); NEN+Domp (N=21 cells)) was quantified and analyzed by one-way ANOVA with Tukey post-hoc test (for LC3-II) or Kruskal-Wallis with Dunn´s post-hoc test (for Lamp1 and p62). * p< 0.05; ** p< 0.01;*** p< 0.001; **** p < 0.0001.
