Cancer Cell Targeting
Solute Carriers (SLCs) as well as ATP-binding cassette (ABC) transporters, so-called efflux transporters are over-expressed in many different types of cancer cells and in solid tumors. Thus, SLCs can be utilized for cancer cell-targeted selective drug delivery or to inhibit and starve the cancer cell from essential nutrients. ABC transporters, on the other hand, have a crucial role in cancer biology and more importantly in chemoresistance, as they can pump a wide range of chemotherapeutics out of the cancer cells and thereby reduce the efficacy of these anti-cancer drugs. Therefore, modulating selectively efflux transporters’ expression and/or may offer a potential alternative to improve the efficacy of chemotherapeutics.
The main aim of our research group is to study:
1. SLCs, such as LAT1, as Selective Carriers of Chemotherapeutics
2. Modulation of ABC Expression/Function via Cancer Cell-Targeted Agents
3. Inhibition SLCs to Prevent Cancer Cell Proliferation
