Glucose Transporter 1-Mediated Transcytosis of Glucosamine-Labeled Liposomal Ceramide Targets Hypoxia Niches and Cancer Stem Cells to Enhance Therapeutic Efficacy

Experimental results indicate that glucosamine-labeled liposomal ceramide can be efficiently transported between cancer cells by GLUT1 transporters and substantially accumulated in the hypoxic area in in vitro CSC spheroids and in vivo tumor xenografts.
