Figure 3

Increased level of GTP-bound Rab5 and Rab7 was detected in Line 78 E18 brain samples. Brain lysates were incubated with GTP-agarose beads to pull down activated GTP-bound Rab5 (A) as described in Materials and Methods. The levels of GTP-Rab5 in these samples were quantitated and normalized against internal control. Samples from Line 78 mice show an 89% increase over non transgenic controls (B). Similarly, activated Rab7 was pulled down (C) and a significant increase of GTP-Rab7 is seen in PDGF-β-ASYN-GFP mice as compared to non-transgenic controls (D). For B and D, results are from 6 animals per group. ***p < 0.01. Mouse brain homogenates were immunoprecipitated with an antibody recognizing dynein intermediate chain (DIC). Immunoprecipitates were analyzed by SDS-PAGE/immunoblotting with antibodies as indicated (E). At least three independent experiments were performed for all the studies presented. When possible, all original, full size, uncut blots are presented in Supplemental Information. Otherwise, the original blots are presented in Supplemental Information.
