Figure 6From: Anticancer drug-loaded multifunctional nanoparticles to enhance the chemotherapeutic efficacy in lung cancer metastasis In vivo antitumor efficacy study in A549 cells bearing xenograft tumor model after intranasal treatment of free DOX, GNP, and EGNP. (a) In vivo anti-tumor effects (b) lung tumor mass (c) body weight changes (d) survival rate of mice. Each data point was represented as mean ± sd (n = 4). ***p < 0.0001 is the statistical difference between EGNP and control. **p < 0.001 is the statistical difference between EGNP and GNP.Back to article page
