Ambroxol treatment significantly increases glucosylceramidase protein levels. Representative western blots showing increased glucosylceramidase protein levels and decreased cathepsin D levels with ambroxol treatment. ‘+’ represents lanes treated with ambroxol. Ambroxol treatment resulted in a significant elevation of glucosylceramidase protein levels in control [median increase 30% of untreated cells (IQR 15–40%), Mann-Whitney U-test P = 0.0085], Gaucher disease (GD) [median increase 100% of untreated (IQR 87–200% increase), P = 0.004], Parkinson’s disease with GBA mutations (PD-GBA) [median increase 50% of untreated (IQR 40–130%), P = 0.04] and non-manifesting carrier (NMC) fibroblasts [median increase 35% of untreated cells (IQR 25–40% increase), P = 0.008]. Results are derived from all cell lines in each group and represent median value and IQR.
