(B) Lysates from U20S or tetracycline-inducible VCP-WT, -EQ, -RH, or -AE cells after autophagic induction via nutrient deprivation for 0, 2, 4, or 6 h and immunoblotting for LC3 and α-tubulin. LC3II degrades in control and VCP-WT but degrades less efficiently in mutant (EQ, RH, or AE)-expressing cells. (C) Graphical representation of densitometric evaluation of LC3II and α-tubulin at each time point from three independent experiments.
