Drug reduces fat by blocking blood vessels
Date:4/23/2013

BOSTONResearchers have long known that cancerous tumors grow collections of abnormal blood cells, the fuel that feeds this disease and keeps it growing. Now, new evidence in an animal model suggests that blood vessels in the fat tissue of obese individuals could provide the same purposeand could provide the key to a new way for people to lose weight. When researchers Jian-Wei Gu, Kristina L. Makey, Edmund Chinchar, Carissa Howie, and Lucio Miele, all from the University of Mississippi Medical Center, gave obese mice a cancer drug that works by inhibiting the growth of blood vessels, these mice lost about 70 percent of their fat mass.

The team will discuss an abstract of their study entitled, "Angiogenesis Inhibitor, Sunitinib, Significantly Reduces Adipose Tissue Mass in High Fat Diet-Induced Postmenopausal Obese Mice," at the Experimental Biology 2013 meeting, being held April 20-24, 2013 at the Boston Convention and Exhibition Center, Boston, Mass. The poster presentation is sponsored by the American Physiological Society (APS), a co-sponsor of the event. As the findings are being presented at a scientific conference, they should be considered preliminary, as they have not undergone the peer review process that is conducted prior to the data being published in a scientific journal.

Treating Fat and Cancer the Same

Dr. Gu, who led the research team, notes that there are only three drugs currently approved in the United States to treat obesity. Unfortunately, he says, these few drugs are only minimally effective and come with a host of undesirable side effects.

"Right now," he says, "we don't have good drugs that lead to very significant weight loss, and none that don't cause other problems."

More than a decade ago, Judah Folkman of Harvard Medical School, whose primary research focus was the growth of blood vessels in cancerous tumors, discovered that fat tissue in mice can be regulated by angiogenesis inhib
