OSU Bioresearchers Develop Trojan Horse for Leukemia Cells

Posted by Sam Asher on Thu, Feb 25, 2016

Developing a novel cancer-busting drug is only useful if it can actually be administered to the affected area. We saw last July how UIUC researchers are sneaking drugs past the immune system so they don’t get destroyed in transit. Taking the next step, researchers at The Ohio State University are developing a “Trojan horse” that allows drugs to successfully invade leukemia cells.

He noticed that the cells were not actually resisting the drug but in fact pumping it back out before it reached its critical target. In an effort to evade the pumps, Byrd folded up the drugs in DNA using a process known as "DNA origami." The cell doesn’t recognize the intruder as dangerous until it releases the drugs in the heart of the cell, by which time it is too late.

“Cancer cells have novel ways of resisting drugs, like these pumps, and the exciting part of packaging the drug this way is that we can circumvent those defenses so that the drug accumulates in the cancer cell and causes it to die,” says Dr. Byrd in the OSU article highlighting the success of his discovery. 

“Potentially, we can also tailor these structures to make them deliver drugs selectively to cancer cells and not to other parts of the body where they can cause side effects.”

Funding for the research came from start-up funds provided by the Department of Mechanical and Aerospace Engineering, the Leukemia and Lymphoma Society, the National Cancer Institute, the D. Warren Brown Foundation, Four Winds Foundation and the Harry T. Mangurian Jr. Foundation. For more details on funding for research at Ohio State University, peruse our Ohio State University Funding Report:
