New bio agent found to starve liver cancer

LOCAL scientists have developed a new technology to restrain the growth and spread of cancer cells. Pre-clinical tests have found their new biological agent effective on cancer, especially on liver cancer, officials from the Shanghai Institute for Biological Sciences under the Chinese Academy of Sciences said today.

Scientists found they can starve cancer cells by blocking blood vessel growth and interfere the fusion of two target proteins in liver cancer cells.

"We discovered the mechanism and have got a patent in China and some major western countries," said Wu Jiarui, the institute deputy director.

The institute has transferred the patent to pharmaceutical giant, Sanofi-Aventis, for new drug development.

"It should take about 10 years for clinical tests and new drug approval. So far there is only one liver cancer drug in the world and it can only prolong the life of liver cancer patients by normally three months," said Frank Jiang from Sanofi-Aventis.
