Basic research: Understanding why the naked mole rat is cancer resistant

The naked mole rat's lifespan of 30 years is remarkable, as is its natural resistance to cancer. Researchers have now identified a mechanism responsible for the latter: high levels of high-molecular-mass hyaluronan secreted from fibroblasts, which accumulates because of decreased activity of hyaluronan-degrading enzymes.
