Furthermore, overall survival of 161 patients with follow-up data displayed that higher Hsp90ab1 expression was significantly correlated with reduced overall survival in GC patients (Fig. 2c, log-rank test = 12.0, P < 0.001), which was supported by public data from Kaplan–Meier plotter using Gene Expression Omnibus and TCGA datasets (Figure S1C-D) (KM plotter, http://kmplot.com)[31, 32]. The gene discussed is HSP90AB1; the disease is gastric cancer.
