A Virus May Be One Cause of Prostate Cancer

A new study published in the Proceedings of the National Academy of Sciences may lead to exciting discoveries regarding prostate cancer. By analyzing samples of prostate cancers scientists discovered that 27% of them contained xenotropic murine leukemia virus-related virus (XMRV). XMRV is a virus that is known to cause leukemia and tumors in animals. Even though it has been found in association with human prostate cancer, there’s not evidence that it is the specific cause of the disease. However, it is an important question that needs to be answered. Another well-known virus that can cause human cancers is the human papilloma virus (HPV). Prostate cancer is the second most common cancer among men, after lung cancer, killing approximately 250,000 men annually. [via ABC News]

Bone Marrow Transplant Hints At AIDS Cure

Last month physicians in Germany reported that a man co-infected with leukemia and HIV is free of both diseases two years after receiving a bone marrow transplant. The excitement centers around the use of bone marrow from a donor who has natural immunity to the HIV virus. Approximately one in 1,000 Europeans and Americans have an inherited genetic mutation which prevents HIV from attaching itself to our immune cells. This is a very unique case in that a matched donor just happens to be one of those who have immunity to HIV. However, researchers at UC Davis are actively working on a cure by playing on the same idea – by replacing HIV-infected individuals’ immune systems with genetically engineered stem cells that are resistent to the HIV virus.
