Meanwhile, miRNAs also interacted with some other conserved signalling pathways, such as TLR4, Wnt//β‐catenin and phosphatidylinositol 3‐Kinase/Protein Kinase B, to influence cancer cell proliferation, metastasis or maintenance of cancer cell stemness.108, 109, 110, 111. The gene discussed is TLR4; the disease is cancer.
