The aim of the present study was to investigate the influence of the nitric oxide donor prodrug JS-K (C13H16N6O8) on Taxol-induced apoptosis in prostate cancer cells, and to investigate a potential reactive oxygen species (ROS)-associated mechanism. The effect of JS-K on the anticancer activity of Taxol was assessed in prostate cancer cells; cell viability, colony formation, apoptosis, ROS generation and expression levels of apoptosis-associated proteins were investigated. The function of ROS accumulation in the combined effects of JS-K and Taxol was determined using the antioxidant N-acetylcysteine (NAC) and the pro-oxidant oxidized glutathione (GSSG). The results of the present study demonstrated that JS-K was able to increase Taxol-induced suppression of prostate cancer cell proliferation, apoptosis, ROS accumulation and upregulation of apoptosis-associated proteins. Furthermore, NAC reversed the effect of JS-K on Taxol-induced apoptosis and conversely, the pro-oxidant GSSG exacerbated the effect of JS-K on Taxol-induced apoptosis in prostate cancer cells. In conclusion, JS-K enhances the chemosensitivity of prostate cancer cells to Taxol, via the upregulation of intracellular ROS.

Considerable development in the application of injectable drug delivery systems for cancer therapy has occurred in the last few decades. These improvements include liposomes, lipid nanoparticles (LNPs), and other nanoparticles with or without macromolecular conjugates. For example, liposomal doxorubicin modified by poly(ethylene glycol) (Doxil) was the first liposome with anti-cancer effects which was approved by the US Food and Drug Administration, whereas Abraxane (modified albumin nanoparticles loaded by paclitaxel) was recently confirmed for the treatment of breast cancer. Recently, drug delivery systems by LNPs are an emerging technology with numerous advantages over conventional liposomes and chemotherapy using free drug treatment of cancer. These properties are biocompatibility, controlled and sustained release of anti-tumor drugs, and lower toxicity. Valuable experiments on these drug delivery systems offer better treatment of multidrug-resistant cancers and lower cardiotoxicity. LNPs have been presented with high functionality in chemotherapeutic targeting of breast and prostate cancer. The basis for this targeting behavior has been shown to be both passive and active targeting. The main objective of this review was an overview of the current position of the liposome-based drug delivery systems in targeted anticancer chemotherapy.
