GPX8 expression is associated with poor patient prognosis. (A) KM survival plots for patients with breast cancer divided into high GPX8 expression (“high” [red]) and low (“low” [black]). The columns represent overall survival data of all breast cancers (Breast Cancer). Number in parentheses indicates the total number of patients. These plots were generated in the KM plotter website. The GPX8 228141_at Affymetrix ID symbol was used for all of the analyses. The P value (P), the hazard ratio (HR), and the number at risk were determined by the analysis tool. (B) GPX8 expression effects on patient overall survival are more profound in the aggressive breast cancers subtypes. KM plots represent the overall survival data from breast cancers; Luminal A, Luminal B, Her2+, and Basal subtypes. (C) Overall survival data of GPX8 expression levels in lung (Lung Cancer) and gastric cancers (Gastric Cancer).
