Search using influenza virus to fight cancer
BUENOS AIRES - Virus attacked genetically modified tumor cells, according to a study published in the journal "Molecular Therapy." Fundación Instituto Leloir, Argentina managed to adapt a virus that causes influenza and conjunctivitis - adenovirus - to combat skin cancer and pancreas in rats.
The team manager Osvaldo Podhajcer, head of the Laboratory of Molecular and Cellular Therapy and researcher at the National Scientific and Technical Research of Argentina (CONICET), told the BBC that they were able to reduce or eliminate tumors without damaging other tissues.
- For the first time we can genetically engineer a virus to use its features against cancer cells - said.
This was possible because scientists have modified the DNA of the virus to reproduce it only in cancer cells.
- These cancers are the least likely to receive surgical treatment - told the BBC the oncologist Eduardo Cazap, former president of the Union for International Cancer Control.
Genetic modification of a virus is usually seen with fear, mainly it from spreading and causing a pandemic ends. Therefore, the experts chose the adenovirus, less dangerous and very stable, they said, which dismisses the danger of mutation. Furthermore, Podhajcer explained that chose these two types of cancer because there is no known treatment and they have a high incidence in the population.
