Mrp1: A Target For Hematopoietic Stem Cell Diseases, Cassandra Reiling

Theses and Dissertations--Toxicology and Cancer Biology

Multidrug resistance-associated protein 1 (MRP1) is a member of the adenosine 5’-triphosphate (ATP)-binding cassette (ABC) transporters. MRP1 actively effluxes a variety of endogenous and exogenous substrates from cells, ultimately, working to remove these compounds from the body. MRP1 was initially discovered based on its ability to confer resistance against a variety of chemotherapeutics when overexpressed in cancer cells lines. MRP1 function is important for a number of physiological processes, including regulating cellular and extracellular levels of the anti-inflammatory leukotriene C4 (LTC4) and the antioxidant glutathione (GSH). Our studies have focused on the role of MRP1 in regulating hematopoietic stem cell …
