Overexpression of BICD2 mutants in rat hippocampal neurons results in a decrease in neurite length. (A) Representative images of hippocampal neurons overexpressing mCherry–BICD2FL (WT and mutants) or an empty plasmid control; neurons were also cotransfected with soluble GFP in order to mark the neurites. Bar, 10 µm. (B) Axon length after 3 d of overexpression of BICD2FL constructs; mean and SD from n = 3 independent experiments (each experiment measuring 15–20 neurons for each construct); *, P ≤ 0.05. (C) Total neurite length after 3 d of overexpression of BICD2FL constructs; mean and SD from n = 3 independent experiment (each experiment measuring 15–20 neurons for each construct); **, P ≤ 0.01. (D) Model of how a gain of function in dynein-based motility from BICD2 mutants might cause an imbalance in axonal transport and lead to SMA. See Discussion for more details.
