Oxidative stress‐induced off‐target effects limit the therapeutic window of radiation therapy. Although many antioxidants have been evaluated as radioprotective agents, none of them are in widespread clinical use, owing to the side effects of the antioxidants themselves and the lack of apparent benefit. Aiming for a truly effective radioprotective agent in radiation cancer therapy, the performance...
The critical importance of reactive oxygen species (ROS) as oncogene activators and essential secondary messengers in cancer cell survival have been widely reported. Since oxidative stress has been implicated as being pivotal in various cancers, antioxidant therapy seems an apt strategy to abrogate ROS-mediated cellular processes to attenuate cancers. We therefore synthesized ROS scavenging nitroxide...
Early diagnosis of metastatic cancers could greatly limit the number of cancer-associated deaths. Aberrant surface expression of sialic acid (hypersialylation) on tumors correlating with metastatic incidence and its involvement in tumorigenesis and progression is widely reported; hence detection of hypersialylated tumors may be an effective strategy to identify metastatic cancers. We herein report...
Multidrug resistance in cancer cells contributes to the failure of conventional chemotherapy in more than 90% of cancer patients (metastatic). This is attributed to reactive oxygen species (ROS)-regulated drug efflux proteins, P-glycoprotein (P-gp) and multidrug resistance-associated protein 1 (MRP1). In this study, we focused on overcoming multidrug resistance with a therapeutic application of ROS-scavenging...
