Conventional cancer chemotherapies are often limited by their non-targeted nature and their inadequate delivery to the tumor affecting the normal tissues and leading to toxic adverse effects. In order to improve the anticancer efficacy and safety of these drugs, as well as the diagnosis capacity of imaging agents, nanoparticles drug delivery system has been developed combining ligands enabling tumor targeting at a cellular level and drug carrier capacity. Nucleolin (NCL) is a multifunctional protein that could shuttle from nucleolus to nucleoplasm, cytoplasm and cell surface. This ribonucleo protein over expressed at the cell surface of cancer cells is involved in many cancer processes supporting tumorigenesis such as cell proliferation and apoptosis. Additionally, NCL expression is enhanced in angiogenic vessels, enabling multi-targeting strategies t.. View More»
