What is it about?

Cancer metastasis is one of the most deathly consequences of cancer. We describe the preparation and evaluation in a mouse model of a protein nanoparticle carrying several units of an anticancer drug (floxuridine) that is given intravenously. The nanodrug is able to circulate in the blood and find the metastasic cells by binding to an overexpressed receptor (CXCR4) present in Cancer Stem Cells. The efficient removal of the metastasic cells is proven in several mouse models.

Why is it important?

The manuscript defines a potential therapeutic solution for the treatment of metastasis from colon cancer.


It is the best result in my career as it provides a novel approach to treat one of the main health problems. A strong and long coordination of three research groups belonging to the Spanish Health Network (CIBER-BBN)was needed, showing the importance of interdisciplinary networks. Funding from La Marato de TV3 was indeed key to achieve success.
