Recent Studies from Nanjing Medical University Add New Data to Xenografts [Enhanced Antitumor Efficacy by D-Glucosamine-Functionalized and Paclitaxel-Loaded Poly(Ethylene Glycol)-Co-Poly(Trimethylene Carbonate) Polymer Nanoparticles]

By a News Reporter-Staff News Editor at Biotech Week -- Research findings on Biotechnology are discussed in a new report. According to news originating from Jiangsu, People's Republic of China, by NewsRx correspondents, research stated, "The poor selectivity of chemotherapeutics for cancer treatment may lead to dose-limiting side effects that compromise clinical outcomes. To solve the problem, surface-functionalized polymer nanoparticles are regarded as promising tumor-targeting delivery system."

Our news journalists obtained a quote from the research from Nanjing Medical University, "On the basis of glucose transporter (GLUT) overexpression on cancer cells, D-glucosamine-conjugated and paclitaxel-loaded poly(ethylene glycol)-co-poly(trimethylene carbonate) copolymer nanoparticles (DGlu-NP/PTX) were developed as potential tumor-targeting drug delivery system in this study. Because of the high affinity between D-glucosamine and GLUT, DGlu-NP/PTX could target to tumor tissue through GLUT-mediated endocytosis to improve the selectivity of PTX. DGlu-NP/PTX was prepared by emulsion/solvent evaporation technique and characterized in terms of morphology, size, and zeta potential. In vitro evaluation of two-dimensional cells and three-dimensional tumor spheroids revealed that DGlu-NP/PTX was more potent than those of plain nanoparticles (NP/PTX) and Taxol. In vivo multispectral fluorescent imaging indicated that DGlu-NP had higher specificity and efficiency on subcutaneous xenografts tumor of mouse. Furthermore, DGlu-NP/PTX showed the greatest tumor growth inhibitory effect on in vivo subcutaneous xenografts model with no evident toxicity."

According to the news editors, the research concluded: "Therefore, these results demonstrated that DGlu-NP/PTX could be used as potential vehicle for cancer treatment."
