Identification and Validation of FGF-Related Prognostic Signatures in Prostate Cancer

Figure 2

The landscape of FGF-related genes in prostate cancer. (a) Heat map of FGF-related genes in normal samples and PCa samples from TCGA database (the right ordinate represents differential gene names; the left dendrogram represents differential gene expression clustering; each small square represents the expression of a gene in one sample, and the upper right histogram is color scale. (b) Pearson correlation analysis of FGF-related genes (the number in each circle in the figure indicates the correlation coefficient between the two genes, and the ∘ marker indicates that the two genes are not significantly correlated). (c) Box plot of the expression of FGF-related genes in normal control samples and PCa samples (abscissa indicates gene name and ordinate indicates gene expression value; blue is for normal samples and red for HNSCC samples). (d) The protein-protein interaction network of FGF-related genes (each node in the figure represents a protein and the edge between the nodes represents the interaction between the two proteins). Red circles represent the protein products of upregulated genes; green circles represent the protein products of downregulated genes. The smaller the value after correction is, the more significant the difference is.
