Multidrug screening. A, LINCs strategy to identify compounds with signatures similar to CBX. B, Fluid-phase endocytosis was analyzed by Alexa 488-dextran uptake (as in Fig. 5C). Data are mean ± s.e.m. from 4 to 8 independent experiments for each small molecule, one-way ANOVA with Holm-Sidak’s multiple comparisons post-hoc for analyzing differences of vehicle treated Cln3R MBECs with respect to all other groups. C, Phosphorylated Cav-1(P-cav1) levels in Cln3R and Cln3−/− MBECs after small molecule treatment. Data represent mean ± s.e.m. from six independent experiments, non-parametric Mann-Whitney test with Bonferroni‘s multiple comparison correction for vehicle treated Cln3−/− MBECs with respect to all other groups. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001.
