Researchers led by Jeevisha Bajaj published earlier work showing taurine can fuel leukemia stem cells. The new paper in Cell Death & Disease looks at the bone marrow microenvironment and how cancer cells use taurine there.
PhD candidate Christina M. Kaszuba led experiments in mice and the lab. Mice that could not take up taurine had weaker, more brittle bones. The team studied mesenchymal stromal cells (MSCs), which become bone and cartilage, and found a taurine transporter gene is enriched in these cells. Scientists will study whether blocking taurine to fight leukemia or giving taurine to help bone is the better choice. Bajaj says people with cancer should ask their oncologist about supplements.
