Protein-based Drug Transport

Protein-based drug transporters are found in most tissues including liver, kidney, intestine, and brain. These transporters are particularly important in cancer treatment and multi-drug resistance research. Understanding the specific mechanisms of tumor cell transporters is becoming an essential aspect of chemotherapeutic drug design.
