A. Volcano plots of differentially expressed genes in pair-wise comparison of 40-day Drosophila treated without ALA administration to 40-day Drosophila treated with 0.5 mM ALA administration. Blue symbols indicate significantly downregulated mass bins (Log2 FC < -0.6 and p < 0.05), red symbols indicate significantly upregulated mass bins (Log2 FC > 0.6 and p < 0.05), and gray symbols indicate mass bins that were not significantly changed.
