Fig. 1From: Sex-dependent effect of sublethal copper concentrations on de novo cholesterol synthesis in astrocytes and their possible links to variations in cholesterol and amyloid precursor protein levels in neuronal membranesCell viability. Astrocytes were cultured and treated for 24 h with increasing concentrations of CuSO4. Cell viability was determined by resazurin assay. Results were calculated using ANOVA and Bonferroni’s multiple comparisons test, and data expressed mean ± SD percentage of control (n = 6 for each concentration used). Statistical differences are indicated as ***p < 0.01Back to article page
