TP53 and lung adenocarcinoma: fabricated HA‐based nanoparticles (NPs) for co‐delivering wild‐type (wt‐) p53 and microRNA‐125b (miR‐125b) plasmid DNA to transfect SK‐LU‐1 human lung adenocarcinoma.[136] This strategy significantly up‐regulated wt‐p53 and miR‐125b gene expression and thus promoted cell apoptosis.
