Fig. 7From: Hyaluronic acid-coated chitosan nanoparticles induce ROS-mediated tumor cell apoptosis and enhance antitumor efficiency by targeted drug delivery via CD44Western blot analyses. The results show the expression levels of cleaved caspase 3, caspase 9, Bcl-2, and cytochrome C in A549 cells treated with free 5-Fu, 5-Fu-loaded CS NPs, 5-Fu-loaded HA-coated CS NPs, and 5-Fu-loaded HA-coated CS NPs combined with NACBack to article page
