The A549 tumor-bearing mice model was also exploited in antitumor assessment. In addition, ICP-MS, blood cell analyzer and blood biochemistry analyzer are applied for assessing the biosafety of NPs.Results: Both 356-modified gold nanospheres and nanorods showed antitumor activity. However, 356-loaded gold nanorods are found to have better tumor inhibitory activity than 356-loaded gold nanospheres in the presence of laser and without laser irradiation. Thus, 356-loaded gold nanorods are selected to be applied for chemo-photothermal combined therapy on in vivo. We find that combination therapy could inhibit tumor growth and reduce lung tumor metastasis and inflammatory infiltration compared with individual therapy. It triggers apoptosis in tumor tissue observed by TUNEL assay and TEM pictures.Conclusion: Thus, an RGD targeting and PAD4 inhibitor-loaded system are established based on chemo-photothermal combined therapy. It could inhibit tumor growth, prevent lung metastasis and improve biosafety.Keywords: gold nanospheres, gold nanorods, PAD4 inhibitor, chemo-photothermal combined therapy, biosafetyLu YPeng ZZhu DJia YTaledaohan ALi YLiu JWang YWang YDove Medical Pressarticlegold nanospheresgold nanorodspad4 inhibitorchemo-photothermal combined therapybiosafetyMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 16, Pp 5565-5580 (2021)
