Core Insights - Greenland sharks exhibit signs of cardiac aging at a young age but maintain heart function, indicating an evolutionary adaptation to chronic oxidative damage [1][2] Group 1: Research Findings - Researchers analyzed heart samples from six Greenland sharks aged between 100 to 150 years, revealing significant fibrosis and accumulation of oxidative damage markers, specifically lipofuscin and 3-nitrotyrosine [1] - Despite the presence of these aging markers, the sharks were in good health and showed no abnormalities in physiological function, suggesting robust myocardial cell vitality [1] Group 2: Implications - The ability of Greenland sharks to withstand chronic oxidative damage without a decline in heart function may be crucial for their exceptional longevity, providing new insights for improving heart health in the elderly [2]
