A new study by researchers at the University of California, Los Angeles, has found that moderate-to-vigorous physical activity may lower the risk of developing glaucoma by up to 73%. Individuals who are physically active appear to have a 73% lower risk of developing glaucoma. Image credit: Steve Buissinne. Glaucoma is one of the leading causes of blindness in the United States. Treatment can slow its progression, but there is no cure. It has long...

![KLFs are a subfamily of zinc finger transcriptional regulators with highly characterized roles in proliferation, survival, metabolism, and response to stress. Hsieh et al demonstrate that KLFs are critical determinants of aging, influencing both lifespan and age-related deterioration, and are broadly required for lifespan extension in all four mechanistically distinct longevity models tested. Importantly, the team provides evidence that these effects are mediated by KLF regulation of autophagy (autophagy was assessed using a GFP::LGG-1 translational reporter; GFP-positive puncta [red arrow] were counted in 30-150 total hypodermal seam cells in 10–20 animals) and are conserved in a mammalian system via a functional ortholog, KLF4. Together, the findings provide a role for the KLFs as a transcriptional regulatory point in longevity.
