MiRNA302e can induce the production of pluripotent stem cells (Zhang and Wu, 2013); miRNA-206 can inhibit the development of breast cancer (O’Day and Lal, 2010); miRNA-134 can inhibit lung cancer cells by targeting the epidermal growth factor receptor (Qin et al., 2016); miRNA-340 inhibits tumor cell proliferation and induces apoptosis in endometrial carcinoma cell line (Xie et al., 2016). Here, EGFR is linked to breast cancer.
