Molecule secreted by cancer-associated fibroblasts promotes anticancer drug resistance

Joint research at Kumamoto University in Japan discovered a new mechanism for anticancer drug resistance in gastric cancer. Experiments clarified that the Annexin A6 molecule contained in extracellular vesicles (EVs) is secreted by cancer-associated fibroblasts (CAFs) and taken up by gastric cancer cells, resulting in resistance to anticancer drug treatment. New drug development that targets Annexin A6 and cancer-associated fibroblasts (CAFs) may be possible.
