Polymeric Na**particles to Make Sure Cancers Don’t Recur
Polymeric Na**particles to Make Sure Cancers Don’t Recur
[IMG]http://cdn.medgadget.com/wp-content/uploads/2015/06/na**particles-against-cancer-stem-cells.png[/IMG] While chemotherapy may be highly effective at eliminating a tumor, there are often cancer stem-like cells that survive and begin forming a new tumor. That’s because these cells are typically more resistant to chemo. Researchers at*Ohio State University have **w developed a new na**particle designed to specifically attack these tumor reinitiating cells to prevent the cancer from coming back. The Polymeric Na**particles are coated with chitosan, specifically targeting a receptor on the cancer stem-like cells. A large dose of doxorubicin, a common chemo drug, is encapsulated within the na**particles. In order to release the poiso**us compound at the right place, the Na**particles were designed to break open when inside an acidic environment of*the type that exists inside of tumors. The team tested the new Na**particles on mice with human breast tumors, showing that the technique increases the cytotoxicity of doxorubicin by six times when killing cancer stem-like cells, while shrinking the rest of the tumor with ** **ticeable side effects on the animals.
