Figure Lengend Snippet: Overexpression of FoxO gene in adult mosquitoes did not affect lifespan (A) Schematic diagram of FoxO gene insertion position in the rVSV. (B) The growth curves of rVSV and rVSV-FoxO in Vero cells at an MOI of 0.01 ( n = 3, unpaired t test, two-sided). (C–F) Six-day-old females were blood-fed with rVSV-FoxO or rVSV diluted to 1 × 10 8 FFU/mL. Con. was fed with medium. Total RNAs were extracted from 8 mosquitoes (C), 8 midguts (D), 8 ovaries (E), or 8 fat bodies (F) at indicated dpi, and the FoxO expression was measured by real-time qPCR. Data are presented as mean ± SD of triplicate measurements ( n = 3). (G and H) Ten mosquitoes per group were treated with iFoxO and iGFP via microinjection or infected with rVSV-FoxO (rFoxO) and rVSV via blood feeding. Western blotting of these mosquito homogenates was performed using anti-FoxO or anti-GAPDH antibodies. (I) Band intensities of FoxO in (H) were quantified using LiCor Image Studio and normalized to GAPDH. Results are shown as mean ± SD from three independent experiments ( n = 3 biologically independent mixtures; two-way ANOVA test followed by Tukey’s post hoc tests). (J and K) Relative FoxO mRNA levels of ten mosquitoes at 7 days post treatment (unpaired t test, two-sided). (L and M) Survival curves of mosquitoes per group upon different treatments (Kaplan-Meier curves and log rank test). Error bars in graphs represent the mean ± SD. ∗ p < 0.05, ∗∗∗∗ p < 0.0001. ns, not significant; These results are representative of three independent experiments.
