Figure 2

PC loading, \(v_{\ell t}\), computed by PCA applied to time points by applying PCA to gene expression profiles. Open black circles: 1st, (0.61) open red triangles: 2nd (− 0.76), green crosses: 3rd (− 0.24), blue crosses: 4th PC loading (− 0.60). The numbers in parentheses are the Pearson’s correlation coefficients. Hours (horizontal axis) represent the duration after the treatments. The horizontal magenta broken line indicates baseline (zero).
