The Significance of Transferrin Receptors in Oncology: the Development of Functional Nano-based Drug Delivery Systems

Abstract

Anticancer therapeutic research aims to improve clinical management of the disease through the development of strategies that involve currently-relevant treatment options and targeted delivery. Tumour-specific and -targeted delivery of compounds to the site of malignancy allows for enhanced cellular uptake, increased therapeutic benefit with high intratumoural drug concentrations, and decreased systemic exposure. Due to the upregulation of transferrin receptor expression in a wide variety of cancers, its function and its highly efficient recycling pathway, strategies involving the selective targeting of the receptor are well documented. Direct conjugation and immunotoxin studies using the tr..
