South Korea - Scientists Have Developed Cancer-Killing Virus

South Korea - South Korean scientists have said they have developed a new genetically altered strain of virus which is highly efficient in targeting and killing cancer cells.

The new therapy developed by the team from Yonsei University uses a genetically-engineered form of the adenovirus, which normally causes colds.
The adenovirus when injected into cancerous tumors, the virus quickly multiplies in the cancer cells and kills them, they can only target cancer cells and does not harm normal cells, the team said. Following three rounds of injections, more than 90 percent of cancer cells in the brains, liver, lungs and womb of mice disappeared within 60 days, the team said.

"I believe we have found a way to overcome one of the great obstacles to finding a genetically altered viral cure for cancer," Yun Chae-Ok, one of the researchers said.
Clinical tests will be carried out early next year and last 18 months, Yun said.
