Impairment of ALR in GCase deficient SH-SY5Y cells. (A) Under basal conditions (CTR) phospho-S6K was significantly decreased in GCase KD cells. Following starvation (ST) and recovery (REC), S6K phosphorylation recovered although was less in GCase KD cells (n = 5). (B) CBE-treated cells presented decreased phopho-S6K levels under basal conditions and the recovery was less than in untreated cells (n = 3), (C) Lyso ID fluorescence measurements detected a significant decrease in acidic functional lysosomes in GCase KD cells (n = 3). Scale bar 10µm. (D) Total cholesterol levels were increased in GBA1 siRNA-treated cells compared to scramble treated cells (n = 7). All data represent mean ± SD, * P < 0.05.
