Figure 4. Overexpression of DISC1 suppresses dendritic branching of MB neurons.
A. Dendrite branching patterns of wild-type and DISC1-expressing (DISC1OE) γ-neurons. Arrowheads indicate dendritic termini (claws), postsynaptic structures receiving inputs from olfactory projection neurons. Cells were labeled with a membrane-bound GFP (UAS-mCD8::GFP) driven by a MB GAL4-driver, OK107. Scale bar, 10 μm.
B, C. Quantification of dendritic phenotypes of DISC1 single-cell clones. B. Number of dendritic branch points. C. Number of dendritic claws. Partial claws were counted as 0.5. Single-cell clones were induced at an early larval stage and analyzed at young adult stage. *p < 0.05 and **p < 0.01 with one-way ANOVA and Dunnett’s post hoc test, n = 10 ~22.
