Berberine Hydrochloride-Loaded Chitosan Nanoparticles Effectively Targets and Suppresses Human Nasopharyngeal Carcinoma.


Nasopharyngeal carcinoma (NPC) is a common epithelial malignancy that occurs in the nasopharynx and it is one of the high incidences of malignant tumors in China. As previous reports, berberine hydrochloride (BH) possesses a repressive effect on the proliferation of various cancer types. But the application of BH was hampered for a long time due to its hydrophobic properties, along with poor stability and bioavailability. In this study, folate acid modified chitosan nanoparticles loaded berberine hydrochloride (BH/FA-CTS NPs) were prepared by the ionic cross-linking technique, the physicochemical properties and the influence of BH/FA-CTS NPs on proliferation, migration and apoptosis in human nasopharyngeal carcinoma CNE-1 cells were studied in vitro and in vivo. Results of scanning electron microscopy (SEM) images showed that BH/FA-CTS NPs were sphere and the diameter was 258.2±9.1 nm. The drug loading and encapsulation efficiency were 8.17±1.12% and 87.73±4.21%, respectively. The drug release kinetics exhibited a slower and sustained release over a period of 48 h. Moreover, results of MTT assay and scratch assay displayed that BH/FA-CTS NPs inhibited proliferation and migration of CNE-1 cells remarkably. BH/FA-CTS NPs promoted apoptosis and necrosis of CNE-1 cells. And BH/FA-CTS NPs displayed distinguished higher tumor inhibition than control group, free BH and BH/CTS NPs in vivo. Therefore, as a nanocomposite, BH/FA-CTS NPs provide a new method and option for the treatment of nasopharyngeal carcinoma patients.
