Loss of LRRK2 causes age-dependent bi-phasic alterations of autophagy markers or substrates. Western analysis shows bi-phasic alterations of proteins (LC3-I and -II, GATE-16 (#, form I; ##, form II)) involved in the autophagy-lysosomal pathway as well as autophagy substrate (p62) in the kidney of LRRK2-/- mice at the ages of 7 and 20 months compared with their respective wild-type (+/+) controls. Western blots shown were obtained using RIPA buffer-insoluble fractions. The overall contrast and brightness for the GATE-16## panel were adjusted to make the band more visible, since the level of GATE-16 form II is much lower than that of GATE-16 form I. In the bar-graph showing quantification of proteins, the data for LC3-II and form II of GATE-16 from 7 months of age are not included, as these proteins are not detectable in WT controls under these conditions. *, P < 0.05; **, P < 0.01; ***, P < 0.001.
