Figure 1Behavioral phenotypes caused by neuron-specific expression of
Dspastin RNAi and the
Dspastin K467R pathogenic mutant are efficiently antagonized by pharmacological treatment with vinblastine. (
A and
B) Neuronal transgenic expression of
Dspastin RNAi and
Dspastin K467R reduced the longevity of adult flies (
A) and severely impaired adult locomotor performance (
B), causing premature loss of climbing ability. Vinblastine treatment increased adult lifespan (
A) and improved locomotor ability (
B), as judged by the enhanced performance in the climbing assay, of flies expressing
Dspastin RNAi and
Dspastin K467R in neurons. Control genotypes were as follows: Elav-Gal4/+, UAS-
Dspastin-RNAi/+, and UAS-
Dspastin-K467R/+. Experimental genotypes were as follows: Elav-Gal4/+;UAS-
Dspastin-RNAi/+ and Elav-Gal4/+;UAS-
Dspastin-K467R/+.
