Heat map from the hierarchical clustering of differential overlapping lipid in the (a) SCD-overexpression group. b SCD-knockdown group. c SCD-overexpression and SCD-knockdown groups. The scaled expression by row (lipids) is shown as a heat map and is reordered by a hierarchical clustering analysis (Pearson’s distance and Ward’s method) on both rows and columns. The color scale indicates the relative amounts of metabolites: red, higher levels; green, lower levels
