Materials and methods: Tripterine-loaded coix seed oil microemulsion (CT-MEs) was prepared through one-step emulsion method. The morphology, size, and zeta potential of CT-MEs and Tf-CT-MEs were examined by transmission electron microscopy and dynamic light scattering. The cellular uptake and mechanisms of HeLa cells were investigated by flow cytometry. Intratumor penetration was investigated using a HeLa three-dimensional (3D) tumor spheroid as the model. The cytotoxicity of the CT-MEs and Tf-CT-MEs against HeLa cells were evaluated by the MTT assay. Additionally, the apoptotic rate of CT-MEs and Tf-CT-MEs inducing apoptosis in HeLa cells was evaluated. Results: In the physicochemical characterization, coix seed oil and CT-MEs exhibited a small size (32.47±0.15 nm) and nearly neutral surface charge (-0.36±0.11 mV). After modification with transferrin, the particle size of Tf-CT-MEs slightly increased to 40.02±0.21 nm, but the zeta potential decreased remarkably to -13.63±1.31 mV. The IC50 of Tf-CT-MEs against HeLa cells was 0.7260 µM, which was 2.58-fold lower than that of CT-MEs. In cellular studies, the intracellular fluorescence intensity of fluorescein isothiocyanate (FITC)-labeled Tf-CT-MEs (FITC/Tf-CT-MEs) was 2.28-fold higher than that of FITC-labeled CT-MEs (FITC/CT-MEs). The fluorescence signal of Tf-CT-MEs was observed at 350 µm below the surface of the 3D tumor spheroid. The apoptotic rate of cells treated with Tf-CT-MEs was 1.73- and 2.77-fold higher than that of cells treated with CT-MEs and tripterine, respectively, which was associated with mitochondrial-targeted delivery of tripterine. Moreover, Tf-CT-MEs was capable of significantly downregulating the cellular level of antiapoptotic proteins and arrested cell proliferation in the G2/M phase. Conclusion: Taken together, Tf-CT-MEs holds promising potential to be an efficient drug delivery system for combinational therapy of cervical cancer.
