Principal component analysis (PCA) in resistant versus responsive samples. (a) The flowchart of this study. (b) Before removing the outliers, the PCA was performed on the gene expression data. (c) After removing the outliers, the PCA was performed on the gene expression. (d) Volcano plot of DEG by log2 foldchange and value < 0.05. (e) Clustering heat map of the DEG. The expression data for DEG was normalized.
