Nanoparticles and magnetic fields team up to attack tumor cells in mice.
Wednesday, March 28, 2012
Good things come in small packages. Really small packages. Nanoparticles, minute molecular messagers, and alternating magnetic fields, have killed cancerous tumor cells in mice in half an hour without harming healthy cells. UGA scientists have found. The cells were in the necks and heads of the mice. The findings were published recently in the journal Theranostics, according to a UGA press release. The researchers believe this is the first time this cancer type in lab mice has been treated using magnetic iron oxide nanoparticle-induced hyperthermia, or above-normal body temperatures. “We show that we can use a small concentration of nanoparticles to kill the cancer cells,” said Qun Zhao, lead author and assistant professor of physics in…
Vaccine holds great promise for breast and pancreatic cancer cases.
Tuesday, December 13, 2011
From a University of Georgia news release: Researchers from UGA and the Mayo Clinic in Arizona have developed a vaccine that dramatically reduces tumors in a mouse model. The model mimics 90 percent of human breast and pancreatic cancer cases—including those resistant to common treatments. The research was described this week in the early edition of the journal Proceedings of the National Academy of Sciences. The vaccine reveals a promising new strategy for treating cancers with the same distinct carbohydrate signature, including ovarian and colorectal cancers. “This vaccine elicits a very strong immune response,” said study co-senior author Geert-Jan Boons, Franklin Professor of Chemistry and a researcher in the UGA Cancer Center and its …
