Akron researcher awarded NIH grant for advancing 3-D tumor models for anticancer drug testing
Date:10/31/2013

The National Institutes of Health is supporting the work of a University of Akron researcher who may hold the key to improving the effectiveness of cancer treatments. The agency has awarded UA's Hossein Tavana a two-year, $511,000 grant to fund his ongoing efforts to improve the testing and effectiveness of anticancer drugs.

Tavana, an assistant professor of biomedical engineering in the College of Engineering, has developed a method to generate 3-D cultures of cancer cells (spheroids) that better model tumors in the body. These improved models have the potential to dramatically improve the screening and discovery of effective chemotherapeutics, Tavana says.

In support of this novel and promising technology, the NIH awarded Tavana its R21 grant, which is defined by the NIH as a developmental research grant intended to support "exploratory, novel studies that break new ground or extend previous discoveries toward new directions or applications."

Drug testing on 2-D cultures of cancer cells, in which thin layers of cells are treated on a flat dish, does not adequately predict how the drugs will behave in the 3-D environment of the body, Tavana says.

Three-dimensional cultures, on the other hand, in which cancer cells aggregate into spherical clusters, better mimic tumors, allowing for more efficient and cost-effective drug screening and discovery, he adds.

This in turn allows researchers to determine which drugs will best treat particular forms of cancer, eliminating the need to treat patients with a battery of drugs in the hope of finding something that works, Tavana explains.

"Rather than throwing a bunch of different drugs into a patient's body, we can say, 'This particular patient, based on this test, will most likely benefit from this chemo drug.'"

Whereas other labs are generating 3-D cancer cell spheroids, or aggregates, one at a time, Hossein's unique method allows him to generate 384 sphe
