Fig. 7

a Dark-adapted (DA) 8–9-week-old Abca4−/− mice were treated by oral gavage with emixustat (EMX, 40 mg/kg, 24 h), IP-DHA (40 and 150 mg/kg, 6 h), or DHA ethyl ester (Et-ODHA 150 mg/kg, 6 h), pupils were dilated, and mice were exposed to light for 2 h. The mice were returned to the dark for 5 days before full-field ERG recordings. The a-wave amplitudes were recorded at 2-log cd.s/m2 light intensity for each treatment and statistically compared to the amplitude of mice treated with the vehicle (soybean oil). Data are expressed as the mean ± SEM. Three asterisk, one-way ANOVA with Bonferroni’s multicomparison test: p < 0.001, DA (n = 12), 40 mg/kg EMX (n = 11), 150 mg/kg IP-DHA (n = 11), 40 mg/kg IP-DHA (n = 3), 150 mg/kg Et-ODHA (n = 6) vs. soybean oil (oil, n = 18); ns nonsignificant. b Chemical structures of IP-DHA, EMX, and Et-ODHA.
