Mangiferin Attenuates UV-B-Induced Premature Senescence Through Suppression Of Mitochondrial ROS And Restoration Of Mitochondrial Dynamics In Human Dermal Fibroblasts And BALB/C Mice
Our skin faces constant challenges from the environment, and exposure to ultraviolet B (UV-B) radiation is a major factor in premature aging, a process scientists call senescence. This exposure can lead to the buildup of damaging molecules, known as reactive oxygen species (ROS), particularly within the mitochondria—the tiny powerhouses inside our cells. When these cellular powerhouses are compromised, they not only produce more harmful ROS but also experience disruptions in their normal processes, referred to as mitochondrial dynamics, which can accelerate aging. A recent study explored the protective effects of mangiferin, a natural compound. The findings indicate that mangiferin effectively reduces the harmful mitochondrial ROS generated by UV-B exposure. Moreover, it helps to restore the healthy functioning and structure of mitochondria, which is vital for maintaining cell health. These positive effects were observed in human skin cells, specifically dermal fibroblasts, and were also demonstrated in living organisms, using BALB/c mice. This research suggests that mangiferin holds promise as a protective agent against sun-induced skin aging by directly addressing mitochondrial health.
