| Research Abstract |
Oxidative stress is important for longevity regulation. Accumulation of oxidized proteins may induce cellular senescence during aging process. Autophagy, bulky protein degradation pathway promoted the degradation of oxidized proteins under oxidative stress condition in fish. Autophagy inhibition was induced premature senescence by oxidative stress. These findings indicate that autophagy is essential to prevent the oxidized proteins and exhibit anti-aging functions in fish models.
