A Effect of mutations in the RNA polymerase III complex on neuronal necrosis. The images are samples of one chordotonal organ neuron (Ch N), which contains six sensory neurons in a cluster. Compared to the wild-type flies, the activation of neuronal necrosis resulted in Ch N loss in the AGG (Appl-Gal4/+; UAS-GluR1Lc, tubulin-Gal80ts/+; UAS-GFP/+) flies. The white arrows point to the swollen neurons. In the mutants under the AGG background (Appl-Gal4/+; UAS-GluR1Lc, tubulin-Gal80ts/+; UAS-GFP/dBrfc07161 and Appl-Gal4/+; UAS-GluR1Lc, tubulin-Gal80ts/+; UAS-GFP/dPolr3cf05999), the average number of Ch N was plotted. n = 25 chordotonal organs from five larvae. B The climbing ability of AGG flies under the mutant background same as (A). Trial n = 5, 50−60 flies were tested for each trial. C The survival and climbing ability of AG (genotype: Appl-Gal4/+; UAS-GluR1Lc, tubulin-Gal80ts/+; +/+) flies under the mutant or RNAi background (genotype: Appl-Gal4/+; UAS-GluR1Lc, tubulin-Gal80ts/RanG19V,Q69L;+/+ and Appl-Gal4/+; UAS-GluR1Lc, tubulin-Gal80ts/+; UAS-RanRNAi /+). Besides the control under the mutant background (w1118), a genetic background matched RNAi control (TB00072) was also used. This line contains an insert of the transgenic vector into the defined site on chromosome 3. Trial n = 5, 50−60 flies were tested for each trial. D The survival and climbing ability of AG flies under the Ago1RNAi and Ago2RNAi background (genotype: Appl-Gal4/+; UAS-GluR1Lc, tubulin-Gal80ts/UAS-Ago1RNAi; +/+ and Appl-Gal4/+; UAS-GluR1Lc, tubulin-Gal80ts/UAS-Ago2RNAi; +/+). A genetic background matched RNAi control (TB00073) was also used. This line contains an insert of the transgenic vector into the defined site on chromosome 2. Trial n = 5, 50−60 flies were tested for each trial.
