Previous studies have shown that MiR29b negatively regulates migration by downregulating the expression of VEGF (Amodio et al. 2013; Zhang et al. 2014) and IL-8 mRNA expression (Amodio et al. 2013), and clinical studies have shown that miR29b exhibits tumor-suppressive effects in breast cancer (Qin et al. 2015; Shinden et al. 2015). The gene discussed is VEGFA; the disease is breast carcinoma.
