Active MAPK/ERK and NF-κB expression at the protein level was significantly reduced in lung cancer cells transfected with miR-142-3p mimics, while active MAPK/ERK and NF-κB expression was increased in NCI-H3255 cells transfected with miR-142-3p inhibitor (Fig. S4i-j, Fig. S4m). This evidence concerns the gene NFKB1 and lung cancer.
