Clusters of FRG expression in CRC patients and biological characteristics. (a) Three distinct FRG clusters were identified using unsupervised clustering. (b) Survival analyses for the three FRG clusters based on patients with colorectum cancer. (c) Principal component analysis for the transcriptome profiles of three FRG clusters. (d) GSVA enrichment analysis showing the activation states of biological pathways in cluster B vs. cluster C. The heat map was used to visualize these biological processes, red represented activated pathways, and blue represented inhibited pathways.
