MIEF2 and ovarian cancer: Using the online Kaplan–Meier plotter (http://kmplot.com/analysis/), we found that MIEF2 high expression predicts a significant poor prognosis (HR = 1.36, 95% CI: 1.10–1.7, P = 0.0036) in patients with OC (Supplementary Fig. S1A), suggesting a potential oncogenic role of MIEF2 in the progression of ovarian cancer (OC).
