| Outline of Final Research Achievements |
Mechanisms of anti-cancer drug resistance include various factors, such as the increased drug efflux by cancer cells, activation of survival signaling pathways by growth factors. In addition, cancer stem cells have been found in tumors. Cancer stem cells are characterized by the overexpression of ABC transporters, such as P-glycoproteins and breast cancer resistance protein. The expressions of the transporters partially explain the multidrug resistance of cancer. Novel anti-cancer agents and therapies have been developed every year. Besides conventional anti-cancer agents, molecular target drugs for cancer play important roles in the management of cancer therapy. However, some tumors become resistant to these drugs. Medical practice and research based on more scientific evidence are demanded to provide appropriate and high-quality treatments for patients.
