Abstract:
At present, cancer is still one of the most serious threats to human health. Despite the wide application of multiple cancer therapies in clinical practice, the therapeutic effects of most cancers are still far from satisfactory. In recent years, the discovery of regulated cell death may be a good first step on the road to treat cancer. Ferroptosis is triggered by lipid peroxidation of unsaturated fatty acids in cell membrane catalyzed by iron ion. It has been widely concerned as an emerging target for cancer therapy. With the booming of biomedical nanotechnology, ferroptosis as an emerging therapeutic target has attracted extensive attention. Here, we review the advance on the intersection of ferroptosis and biomedical nanotechnology. First, the research background of ferroptosis and nano-preparation as well as the feasibility of ferroptosis-based nano-drug delivery systems (nano-DDS) for cancer treatment are presented and analyzed. Then, the strategies for inducing ferroptosis based on nano-DDS are summarized, mainly including: the promotion of Fenton reaction, the inhibition of glutathione peroxidase 4 (GPX-4) and the restriction of the cysteine-glutamate exchange transporter (system Xc-). Furthermore, the combination therapy strategies based on biomedical nanotechnology induced ferroptosis are also discussed. Finally, we shine the spotlight on the prospects and challenges of ferroptosis-based nanotherapeutics in clinical application.
