For example, overexpression of miR-127–3p could rescue the effects of FOXD3-AS1 on NSCLC progression23; miR-193a-3p can promote lung cancer cell invasion by activating STAT3-mediated epithelial-mesenchymal transitions through exosomes24; and miR‐320b targeting BMI1 regulated by NR2F2‐AS1 may influence the cell proliferation, invasion, and apoptosis of NSCLC.25 Here, PTGDR is linked to lung cancer.
