Scientists from the U.S. have found a natural mechanism by which the human body can overcome the cancer cells.
The researchers found that the first metazoans had an effective system of fight against malignant tumors. Its main element was the small interfering RNA, “turn off” any target gene. In the evolution of the immune system of mammals lost this function, however, in the laboratory managed to force to activate.
Experiments on mice have shown that the distribution of a large number of interfering “molecules-killers” with the help of nanoparticles inhibits the development of defective cells, depriving them of food and leads to the degradation of the tumor tissue. In addition, small RNAS do not cause serious harm to healthy cells. The researchers emphasize that the cancer showed zero resistance to such kind of therapy.
Previously, scientists have found evidence of a direct relationship between alcohol consumption and cancer development. Alcohol can cause development of at least seven types of cancer, not just liver cancer, as previously thought.
