Application of estradiol to a zebrafish model of C9ORF72-ALS reduces cellular stress. (A) The effect of 3 days of metabolic supplementation on zebrafish DsRed expression with 10µM estradiol (30.4% reduction in DsRed expression, Kruskal Wallis H-test with Dunn’s multiple testing correction P = 0.0003), 30 mM inosine (26.1% reduction, P = 0.0024) or 10 µM riluzole (43.9% reduction, P < 0.0001). (B) The effect of metabolic supplementation on zebrafish GFP expression; no significant changes were observed. Untreated Tg indicates transgenic fish treated with 0.1% DMSO vehicle control. NTg indicates non-transgenic fish. Data presented as mean with standard deviation from two independent clutches of fish. ** P≤0.01. ****P≤0.001.
