Story summary

Huntington's disease (HD) wreaks havoc on DNA repair by diminishing the vital molecule PAR, as revealed by researchers at McMaster University. This disruption triggers a cascade of mutations and neurodegeneration. Excitingly, the study proposes that targeting PARP, an enzyme linked to PAR production, may unlock innovative treatments for HD, building on established cancer therapies.
