A Novel Ferroptosis-Related Gene Risk Signature for Predicting Prognosis and Immunotherapy Response in Gastric Cancer

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