Remarkably, overexpression of Sema3A can strongly inhibit NSCLC cell invasion and migration (cell invasion, A549 in Figures 5(c) and 5(d), 95-D in Figures 5(e) and 5(f); cell migration, A549 in Figures 5(c) and 5(d), 95-D in Figures 5(e) and 5(f)). This evidence concerns the gene SEMA3A and non-small cell lung carcinoma.
