Table 1. DSec61α function is involved in polyglutamine-mediated toxicity in Drosophila embryos.
Genotype | Injected gene(s) | Ratio of viable larvae, % (total N) |
---|---|---|
w1118 | hs-GFP | 29.0 (178) |
hs-htt150Q | 9.0 (187) | |
DSec61αEP(2)2567/DSec61αP560 | hs-GFP + hs-lacZ | 31.3 (213) |
hs-htt150Q + hs-lacZ | 25.0 (203) | |
hs-GFP + hs-DSec61α wt | 29.8 (196) | |
hs-htt150Q + hs-DSec61α wt | 10.1 (208) |
Precellularized embryos from WT (w1118) or DSec61α mutant (DSec61αEP(2)2567/DSec61αP560) flies were injected with 100 ng/μl hs-GFP or hs-htt150Q in addition to 50 ng/μl hs-lacZ or hs-DSec61α wt and allowed to develop at 25°C. At 12 h after injection, embryos were heat-shocked at 37°C for 1 h and developed at 29°C for 12 h, and the numbers of hatched larvae were counted.
