It has been reported that miR-155-5p promotes the metastasis of colon cancer cells by targeting the AU-rich element (ARE) in the 3′-UTR region of HuR mRNA to upregulate human antigen R (HuR); colon cancer cells could be inhibited from migrating when miR-155-5p is blocked from binding to the ARE in HuR (Al-Haidari et al., 2018). The gene discussed is ELAVL1; the disease is malignant colon neoplasm.
