Figure 7. ERK1 and ERK2 expression were associated with distinct prognostic features of breast cancer. (A–C) Kaplan-Meier Plotter analysis indicated that high expression of ERK1 was associated with prolonged OS, recurrence and DMFS in patients with breast cancer. (D) Kaplan-Meier Plotter analysis indicated that high expression of ERK1 was associated with prolonged OS in patients receiving endocrine therapy. (E–G) Kaplan-Meier Plotter analysis showed that the high expression of ERK2 was associated with poor OS, recurrence and DMFS in patients with breast cancer. (H) Kaplan-Meier Plotter analysis indicated that high expression of ERK2 was not associated with OS in patients receiving endocrine therapy.
