Cancer-resistant Mouse Developed By Adding Tumor-suppressor Gene

Cancer-resistant Mouse Developed By Adding Tumor-suppressor Gene - ScienceDaily

"...The researchers discovered that the Par-4 gene kills cancer cells, but not normal cells. There are very few molecules that specifically fight against cancer cells, giving it a potentially therapeutic application...Rangnekar's study is unique in that mice born with this gene are not developing tumors. The mice grow normally and have no defects. In fact, the mice possessing Par-4 actually live a few months longer than the control animals, indicating that they have no toxic side effects...The implications for humans could be that through bone marrow transplantation, the Par-4 molecule could potentially be used to fight cancer cells in patients without the toxic and damaging side effects of chemotherapy and radiation therapy..."
