Age-related degeneration is due to accumulated cellular damage, which also includes DNA damage, but it is still unclear about how these types of damage drive aging.
Dr. Paul Robbins and colleagues at the University of Pittsburgh sought to address this question using a mouse model of DNA repair deficiency. The Robbins team found that DNA damage drives aging, in part, by activating NF-κB, a transcription factor that responds to cellular damage and stress. They report that inhibition of NF-κB reduces oxidative stress, oxidative DNA damage, oxidative protein damage, and cellular senescence induced by oxidative damage. Their data suggest that NF-κB inhibitors can mitigate cellular damage and could provide clinical benefit for degenerative changes caused by aging.
