LRRK2 activity regulates glucosylceramide and BMP levels to maintain proper lysosomal function. A ) BMP(22:6/22:6) levels were measured in WT parental A549 cells and two clones of LRRK2 R1441G KI A549 cells; data are shown as mean ± SEM; n = 17 independent experiments, and statistical significance was determined using one-way ANOVA following log transformation. B ) Heatmap showing elevated glycosphingolipids including multiple GlcCer species in whole cell extracts from two clones of LRRK2 R1441G KI A549 cells as compared to parental WT cells. The heatmaps were generated as percent of change by normalizing the average of different groups to the average of the WT group; n = 14 independent experiments. The analytes included had nominal p-values (* p ≤ 0.10) for genotype difference in either clone and were grouped based on lipid class. White in the color scale depicts the WT-vehicle as 100%, red shows an accumulation (capped at 350%), and blue shows a reduction. C ) WT and two clones of LRRK2 R1441G KI A549 cells were treated with vehicle or DNL151 (2µM) for 72 h, and the levels of GlcCer(d18:1/24:1) were measured using LC-MS/MS. Data are shown as mean ± SEM; n = 10 independent experiments, and statistical significance was determined using one-way ANOVA following log transformation. D ) WT and one clonal line of LRRK2 R1441G KI A549 cells were treated with increasing concentrations of DNL151, and the levels of GlcCer(d18:1/24:1) were measured using LC-MS/MS. Data are shown as mean ± SEM; n = 4 independent experiments, and statistical significance was determined using non-linear fit following log transformation. E ) Dose-response curves show the percent inhibition of LRRK2 kinase activity as measured by levels of phosphorylated T73 Rab10 in WT and one clonal line of LRRK2 R1441G A549 cells. Data are shown as mean ± SEM; n = 4 independent experiments, and statistical significance was determined using non-linear fit following log transformation.

Nuclei stained with NucBlue (blue); scale bar = 10 μm. G ) The sum of spot intensities of DQ-BSA signal was quantified per cell in WT and two clones of LRRK2 R1441G KI A549 cells.

The sum spot intensities of DQ-BSA signal were quantified per cell. The DQ-BSA signals were normalized to the median within each experiment and to the WT vehicle control.
