In the clinical context, the use of these materials in the treatment of colorectal cancer should largely enhance drug efficiency and patients comfort, while at the same time minimizing undesired side effects
The new micromaterials developed by researchers are formed by chains of amino acids known as polypeptides, which are functional and bioavailable in the form of nanoparticles that can be released and targeted to specific types of cancer cells, for selective destruction.
The research team analyzed the molecular structure of these materials and the dynamics behind the secretion process, both in vitro and in vivo. In an animal model of CXCR4+ colorectal cancer, the system showed high performance upon subcutaneous administration, and how the released protein nanoparticles accumulated in tumor tissues. It is important to highlight that this accumulation is more efficient than when the protein is administered in blood. This fact offers an unexpected new way to ensure high local drug levels and better clinical efficacy, thus avoiding repeated intravenous administration regimens, explains Professor Antonio Villaverde. "In the clinical context, the use of these materials in the treatment of colorectal cancer should largely enhance drug efficiency and patients comfort, while at the same time minimizing undesired side effects."
