Breast Cancer Recycles Toxic Waste to Restock Nitrogen for Growth

Scientists may have hit upon a new therapeutic strategy against breast cancer with the finding that breast tumor cells recycle the ammonia that is generated as a byproduct of normal cell metabolism  and use the toxic waste as a source of nitrogen to fuel their growth. The studies, by researchers at Harvard Medical School (HMS) and the Broad Institute of MIT and Harvard, showed that while cultured breast cancer cells proliferated and thrived in the presence of ammonia, inhibiting ammonia met
