Key Roles of p53 Signaling Pathway-Related Factors GADD45B and SERPINE1 in the Occurrence and Development of Gastric Cancer

Figure 3

The expression matrix of 27 candidate genes in the p53 signaling pathway in GC tissue samples was classified. (a) The clustering situation of the samples when k = 2. (b) Changes of CDF curve when k = 2–5. (c) Relative change of area under CDF curve when k = 2–5. (d) PCA analysis of differential gene expression profiles. Red dots represent cluster 1, and green dots represent cluster 2.
