Figure 6. An inverse relationship between DUSP2 and HIF-1α in ER negative breast cancer associates with decreased relapse-free survival.
(A) Kaplan-Meier plots of relapse-free survival (RFS) in a dataset of patients with ER-negative breast cancer (n = 788), stratified by DUSP2 expression. Data was obtained from the Kaplan-Meier plotter database [34]. The P value was calculated by a log-rank test. (B) Similar analysis was performed in the same patient database but RFS stratified by HIF-1α expression. (C) A schematic model of hypoxia-mediated lapatinib resistance.
