MKI67 and non-small cell lung carcinoma: In mRNA expression, the correlation between PLK1 and FOXM1 (Spearman: 0.88, p = 1.68e-55; Pearson: 0.86, p = 3.22e-51) or MKI67 (Spearman: 0.89, p = 3.67e-59; Pearson: 0.89, p = 1.13e-59) was positive compared with those of others, including CCNA1 and CCND1, extracted from the cBio-Portal analysis in NSCLC patients (Fig. 1a, Fig. S2c-d, Table S5).
