When starvation therapy meets chemodynamic therapy

Abstract

ABSTRACT: In recent years, starvation-primed chemodynamic therapies (ST–CDT) have become a hot topic in the wake of many discoveries related to the aberrant metabolism of cancer cells and their resistance to traditional chemotherapies, as well as altered redox signaling within tumor cells. Nanotechnology platforms are in a unique position to exploit these interrelated phenomena to realize a therapeutic effect; few therapeutic modalities are able to deliver multiple drugs simultaneously outside of nanotechnology, a basic requirement when striving to exploit a complex, interactive system such as a cancer cell. In this review, the pertinent mechanisms of ST and CDT, as well as the important interactions between these two therapies, are discussed. We outline how these therapies may work synergistically or antagonistically, depending on both the therapeutic design and the system of reactions involved. Lastly, specific applications that nanotechnology is particularly well-suited are given, which may offer improvement over clinical state-of-the-art. Such considerations are important, as nanotechnology has historically encountered great difficulty in clinical translation.
