Boosting Nanomedicine Efficacy with Hyperbaric Oxygen Therapy. Adv Exp Med Biol. 2021;1295:77-95 Authors: Wang X, Li S, Liu X, Wu X, Ye N, Yang X, Li Z Abstract Nanomedicine has been a hot topic in the field of tumor therapy in the past few decades. Because of the enhanced permeability and retention effect (EPR effect), nanomedicine can passively yet selectively accumulate at tumor tissues. As a result, it can improve drug concentration in tumor tissues and reduce drug distribution in normal tissues, thereby contributing to enhanced antitumor effect and reduced adverse effects. However, the therapeutic efficacy of anticancer nanomedicine is not satisfactory in clinical settings. Therefore, how to improve the clinical therapeutic effect of nanomedicine has become an urgent problem. The grand challenges of nanomedicine lie in how to overcome various pathophysiological barriers and simultaneously kill cancer cells effectively in hypoxic tumor microenvironment (TME). To this end, the development of novel stimuli-responsive nanomedicine has become a new research hotspot. While a great deal of progress has been made in this direction and preclinical results report many different kinds of promising multifunctional smart nanomedicine, the design of these intelligent nanomedicines is often too complicated, the requirements for the preparation processes are strict, the cost is high, and the clinical translation is difficult. Thus, it is more p...
