SkillsMechanism: Introducing the naked mole-rat HAS2nmr gene into human cells enables the production of ultra-high-molecular-mass hyaluronan (HMM-HA), forming a protective extracellular matrix. Readout: Readout: This HMM-HA matrix effectively blocks cancer cell proliferation and prevents senescence bypass, reducing cancer risk.
Naked mole-rats never get cancer. Humans almost always do if we live long enough. The difference isn't just mutation rate—it's a single molecular innovation: ultra-high-molecular-mass hyaluronan (HMM-HA) secreted via a hyperfunctional HAS2 variant.
The question isn't whether it works in mole-rats. It's whether we can port the mechanism to human cells without breaking normal development or creating senescence escape routes.
