Therapeutic target to stop cancer metastases found

Washington, Apr 1 (ANI): Scientists from New York University have found therapeutic target to stop cancer metastases.

Published in the Journal of Leukocyte Biology, the new research suggests that combating immune suppressive cells in the liver early after a cancer develops may keep the disease from spreading to the liver.

"Our work may open a new field of experimental therapeutics as combating the eventual development of liver metastases by targeting immune suppressive cells in the livers in patients with early cancer can have great benefit," said George Miller, a scientist involved in the work from the Departments of Surgery and Cell Biology at the New York University School of Medicine.

Miller and colleagues reached this conclusion after conducting experiments in mice.

In the experiments, the researchers used mice that spontaneously developed pancreatic cancer because of a mutation (Kras-mutation) in the progenitor cells of the pancreas, as well as mice with advanced colon cancers that spread to the abdomen. They then studied the expansion of immune suppressive cells in the liver from a very early stage in the cancer development to determine the immune phenotype, stimulus for recruitment, inhibitory effects and tumor-enabling function of these cells. Results suggest that combating immune suppressive cells in the liver early after cancer development may prevent the spread of cancer to this vital organ.

"This study could represent one of those 'a-ha' moments in science where one idea or experiment opens up entirely new ways of approaching and understanding a problem," said Luis Montaner, Editor-in-Chief of the Journal of Leukocyte Biology. "Physicians have known that the spread of cancer to the liver is far too common to occur by chance. Now we know that the immune system likely plays a role in facilitating this process. The next step, obviously, is to learn more so we can prevent it from happening." (ANI)
