The Russian Academy of Medical Sciences affiliated Blokhin Cancer Center, experts in science, after years of research are identified, mouse mammary tumor virus (MMTV) is likely to be caused by human breast cancer, the “culprit” because over half of breast cancer patients people are infected with a virus similar to mouse mammary tumor virus disease
According to Russia’s “scientific information” magazine, research shows that 70% to 72% of breast cancer cells contain a DNA sequence with the mouse mammary tumor virus DNA sequences with the University, and healthy women and women suffering from other types of cancer in vivo has mouse mammary tumor virus did not find traces of the existence.
Russian medical experts through research found that young rats drinking infected milk mouse mammary tumor virus, the virus infection in young mice spleen lymphocytes and intestinal lymphoid tissue, and hibernated. Wait until the beginning of breast development in young rats, the virus will be transferred to the breast area from the lymphocytes and began to breed mice caused by mutations in multiple genes and ultimately to change the mouse mammary stem cells, leading to cancer. Although the kinds of virus present in the mouse salivary gland. Kidneys. Lungs. Spermatheca, and other organs, but the virus during pregnancy and lactation in female mouse reproductive fastest breast.
Russia, the researchers speculate that mouse mammary tumor virus spread in the human body mechanism and the transmission mechanism in mice similar to. In their view, from outside of the virus in entering after the gastrointestinal tract of women who went into the intestinal lymphoid tissue. After the virus DNA will enter into the chromosome of lymphocytes and hiding there. The lymphoid tissue is not only the virus to enter the “door”, or breast tumor tissue after resection of the spread of the virus again, “the source.”
Mouse mammary tumor virus to infect humans in the end it will still need further study.
