Abstract
Tumor-targeted ligand modification and nanosized coloaded drug delivery systems are promising for cancer therapy. In this study, we showed that coix seed oil and tripterine coloaded microemulsions with a transferrin modification (Tf-CT-MEs) could improve the treatment of cervical cancer. Tf-CT-MEs exhibited good stability in serum and a notably synergistic antiproliferation effect. In the HeLa xenograft tumor-bearing mouse model, Tf-CT-MEs accumulated at tumor sites and penetrated deeply in tumor tissues. Tf-CT-MEs had superior anticancer efficacy in vivo, which greatly slowed the growth of tumors (***p < 0.001 vs saline). We also found that Tf-CT-MEs inhibited tumor cell proliferation, enhanced antiangiogenesis, and induced apoptosis by regulating bax/bcl-2 and the activating caspase-3 pathway. Tf-CT-MEs decreased by 27.7, 26.9, 61.2, and 42.5% of concentrations of TGF-β1, CCL2, TNF-α, and IL-6 in serum, respectively. In addition, Tf-CT-MEs showed little toxicity in vital organs. These results were due to the improved drug delivery efficiency. Collectively, Tf-CT-MEs enhance tumor-targeting, facilitate deep penetration of drugs, and have promising potential as an efficient treatment for cervical cancer.
