In keeping with the observed tumor suppressor properties of PLK1, patients with low PLK1 expression were associated with significantly shorter overall survival, compared to those with higher PLK1 expression levels (Fig. 8c, p = 0.0099; hazard ratio (HR), 0.59; 95% confidence interval (CI), 0.40–0.89). The gene discussed is PLK1; the disease is neoplasm.
