- Viral etiology of human breast cancer
- Bovine leukemia virus and its possible role in causing human breast cancer
- Development of early diagnostic tests for infection bovine leukemia and for breast cancer
The following projects relate to our overall hypothesis that bovine leukemia virus (BLV) infects humans and could potentially cause cancer:
- How do humans become infected with BLV? Is it from cattle via bovine food products?
- Can women infected with BLV pass the virus to their children transplacentally or through breast milk?
- Are other human organs besides breasts infected by BLV and could the virus be associated with cancer in these organs?
- Does infection of normal human breast cells with BLV in culture cause them to acquire characteristics of a malignant cell?
