Zhang and colleagues reported that miR-132 levels are lower in non-small cell lung cancer tissues than in adjacent noncancerous tissues and that miR-132-mediated changes in the transforming growth factor β1 (TGF β1)/Smad2 axis suppress tumor cell metastasis by inhibiting cell migration, invasion, and epithelial-mesenchymal transition (EMT) [20]. Here, SMAD2 is linked to non-small cell lung carcinoma.
