However, survival analysis by the Kaplan-Meier plotter29, which curated the survival and gene expression data (Affymetrix microarray platform) of 5,143 breast cancer patients deposited in GEO29, showed patients with high CBX6 expression displayed significantly longer overall survival (OS) (HR = 0.78, P = 0.021) and recurrence-free survival (RFS) (HR = 0.73, P = 2.7e-08) than those with lower CBX6 expression30 (Supplementary Fig. S3). The gene discussed is CBX6; the disease is breast cancer.
