“40,000 women in America will die of breast cancer in 2014.” This is a truly terrifying projection. Breast Cancer is an extremely deadly, and extremely prevalent cancer that affects the lives of millions each year. In my personal experience, I have many friends and family members that have battled against this cancer. So many are affected, and there is still no concrete cure. There is no cure, however, researchers at the University of California, San Diego School of Medicine have identified an enzyme that is closely related to the metastasis of breast cancer cells. This is great news, for it suggests the possibility of further research using this finding to end breast cancer for good. Xuefeng Wu, a lead scientist involved with this research, has stated that the team has been able to “target breast cancer metastasis through a pathway regulated by an enzyme“. This enzyme is called UBC13 and it regulates the activity of a protein called p38.
This p38 protein, when not in use, prevents metastasis. By identifying the enzyme that prevents the use of p38, researchers have come one step closer to preventing the spread of breast cancer in the body, and therefore defeating it. With the use of a lentivirus injected into the mammary tissues of mice, the scientists were able to suppress the functions of both UBC13 and protein p38. The mice grew primary tumors, as was expected, however the primary tumors did not metastasize and spread breast cancer cells throughout the bodies, which means the cancer was stopped from spreading throughout the body. This prohibition of the cancer cells to spread is a major breakthrough in breast cancer research and will without a doubt contribute greatly to the ending of breast cancer.
