KLF4 and invasive breast carcinoma: Actually, deregulation of miR‐204, miR‐200c, miR‐34a, and miR‐10b simultaneously could significantly reduce the survival rate of breast invasive carcinoma via up‐regulation of OCT4, SOX2, KLF4, c‐MYC, NOTCH1, SNAI1, ZEB1, and CDH2 and down‐regulation of CDH1 (Figure 8).
