Analyses of whole tissue homogenates suggests that cells compensate for autophagy deactivation over time. (A and B) Quantitative western blot analyses of detergent soluble lysates of mouse forebrain. Analyses reveal a significant accumulation of synaptic proteins GRIN2B/NMDAR2B, SLC17A7/Vglut1, DLG4/PSD-95, and SYT1 in atg7iKO(3.5) mice, which in atg7iKO(6.5) mice, return to Ctrl levels. VAMP2, SLC32A1/Vgat and SYN1, did not show any change. VCL was used as a loading control. Ctrl, n = 3; atg7iKO(3.5), n = 4; atg7iKO(6.5), n = 4. (C) Chymotrypsin-like activity of the proteasome in forebrain tissue of mice. atg7iKO(6.5) mice demonstrate a significant increase in proteasome activity. Ctrl, n = 3; atg7iKO(3.5), n = 4; atg7iKO(6.5), n = 4. Statistical analyses are found in Table S1. *p < 0.05.
