B. Chemical inhibition of Hsc70 activity in HEK293T cells overexpressing FLAG-DnaJC5 reduces extracellular α-synuclein levels as shown by dot blot. Intracellular levels are shown by Western blotDnaJC5 was detected by FLAG antibody. Quantification of extracellular synuclein levels is shown as average ± SEM, n=3, ***p<0.001 one-way analysis of variance with Tukey's multiple comparison post-hoc analysis.
