Further analysis using the UALCAN website found that compared with patients with low/medium TMEFF1 expression (406 patients), the survival time of patients with high TMEFF1 expression (137 patients) with endometrial cancer was significantly shorter (P=0.025) (Fig. 1D), suggesting that patients with endometrial cancer with high TMEFF1 expression have a poor prognosis. The gene discussed is TMEFF1; the disease is endometrial cancer.
