KLF4 and neoplasm: Therefore, we examined the correlation between NUF2 and tumor stemness markers (Figure 5C), and the results showed that NUF2 correlates with the following tumor stemness markers: MYC (r = 0.181, p < 0.001), KLF4 (r = 0.172, p < 0.001), SOX2 (r = 0.126, p < 0.001), CD44 (r = 0.138, p < 0.001), and POU5F1 (OCT4) (r = 0.429, p < 0.001).
