Figure 4. hsp70 over-expression protects PQ-exposed flies from impaired locomotor performance and poor survival.

(A) Graphical representation of the negative geotaxis assay performed in PQ-exposed w¹¹¹⁸, Df(hsp70), TH-Gal4>w¹¹¹⁸, TH-Gal4>HSP70K71E and TH-Gal4>UAS-hsp70 flies after their exposure to PQ. (B) Survival curve representing pooled data of five independent replicate experiments. Values are mean ± SD (n = 5). Significance ascribed as *p<0.05, **p<0.01 and ***p<0.001 vs. control; ^$$ p<0.01 and ^$$$ p<0.001 vs. TH-Gal4>w¹¹¹⁸; ^## p<0.01 and ^### p<0.001 vs. w¹¹¹⁸.
