MFN1 and Huntington disease: A two-way ANOVA reveals a significant effect of genotype (F(1, 10) = 12.68, p = 0.0052), exposure time (F(3, 30) = 10.12, p < 0.0001), and a time by genotype interaction (F(3, 30) = 3.464, p = 0.0284) on MFN1 expression, indicating that HD cells exhibit a progressive and significant reduction in MFN1 expression that is directly related to the duration of Cd exposure.
