A bioinformatics survey identified 41 candidate miRNAs based on their possibility of suppressing KLF5 expression and other stemness-related signals, such as Wnt/β-catenin signalling and Notch signalling.30–32 Of the listed miRNAs, miR-4711-5p exhibited the strongest anti-tumour effects across CRC cell lines and suppressed cancer stemness. Here, KLF5 is linked to cancer.
