Fig. 2

Boxplots of the expression levels of 30 autophagy-associated genes (AAGs) in tumour and normal tissues. The red box plots above the corresponding gene name represent the expression in tumour samples, whereas the green box plots represent the expression in normal samples; the red dots on the X-axis indicate genes with high levels of expression and the blue dots indicate genes with low levels of expression. (Difference analysis by Wilcoxon signed-rank test and all false discovery rate (FDR) < 0.05)
