Effects of mul1 and park mutations on SOD1 and ROS levels. a SOD1 level in the Drosophila brain (means ± SD). Statistically significant differences were found between all genotypes studied (one asterisks indicates p = 0.05; two asterisks indicate p < 0.05). N of w¹¹¹⁸ = 90, N of park¹ = 90, N of mul1^A6 = 90. b ROS level in the Drosophila brain (four asterisks indicate p < 0.01) (means ± SD). N of w¹¹¹⁸ = 27, N of park¹ = 25, N of mul1^A6 = 28
