The low bioavailability restricts its application as a therapeutic agent. Folate (FA) receptors are highly expressed in many malignant tumors while low expressed in normal tissue. Herein, we developed a self-assembled FA modified MPEG-PCL micelle to incorporate Cur (FA/Nano-Cur) and applied it for colorectal cancer therapy.Methods: We prepared FA/Nano-Cur micelles and identified their characteristics. The drug release behavior, pharmacokinetics and in vitro anti-tumor activities of FA/Nano-Cur were studied. Furthermore, the in vivo anti-tumor ability assessment and anti-tumor mechanisms investigation were carried out in murine colorectal cancer model.Results: FA/Nano-Cur micelles had an average particle size of 30.47 nm. Elongated T 1/2 and larger AUC were found in FA/Nano-Cur group than that in the Free Cur group. MTT assay and apoptotic study indicated the growth inhibitory effect and pro-apoptotic effect of FA/Nano-Cur were the most significant among all treatments. Moreover, the in vivo study demonstrated that FA/Nano-Cur micelles exhibited a much stronger effect to suppress tumor growth, promote tumor apoptosis and attenuate tumor angiogenesis than Free Cur and Nano-Cur micelles.Conclusion: The present study demonstrated FA/Nano-Cur micelles might be a promising therapeutic agent in colorectal cancer treatment with distinctive advantages of improved bioavailability, sustained drug release, tumor-targeted delivery and low toxicity.Keywords: curcumin, colorectal cancer, folate, nanoformulation, apoptosis, angiogenesis |
