Fig. 2From: Effects of MUL1 and PARKIN on the circadian clock, brain and behaviour in Drosophila Parkinson’s disease modelsEffects of mul1 and park mutations on the circadian clock. A–C Expression of selected clock genes in the Drosophila brain at four time points: ZT1, ZT4, ZT13, and ZT16 (means ± SD). Letters a, b, c and d indicate significant differences. Statistically significant differences are between a versus b, a versus c, a versus d, b versus c, b versus d, c versus d (p < 0.01) in each chart. N of w1118 = 60, N of park1 = 60, N of mul1A6 = 60. N of w1118 = 60, N of park1 = 60, N of mul1A6 = 60. D PER protein level in the Drosophila brain at four time points: ZT1, ZT4, ZT13, and ZT16 (means ± SD). Letters a, b, c and d indicate significant differences. Statistically significant differences are between a versus b, a versus c, a versus d, b versus c, b versus d, c versus d (p < 0.05). N of w1118 = 90, N of park1 = 90, N of mul1A6 = 90Back to article page
