The role of SIRT1 in ocular aging.
The sirtuins are a family of enzymes that regulate DNA expression. The sirtuin family helps regulate the lifespan of diverse organisms. Humans have seven different sirtuins (SIRT1-7). This study suggests that SIRT1 may provide protection against diseases related to oxidative stress-induced ocular damage, including cataract, age-related macular degeneration, and optic nerve degeneration in glaucoma patients.
