Hesperidin protects C2C12 myoblasts from oxidative damage by reducing ROS-mediated mitochondrial damage and endoplasmic reticulum stress
Molecular & Cellular Toxicology(2024)
摘要
Hesperidin, a flavanone glycoside found primarily in the peel of citrus fruits, has benefits as a natural compound for preventing various diseases, but its inhibitory effect against oxidative injury in muscle cells has not been reported. The current study aimed to investigate whether hesperidin can prevent oxidative damage in C2C12 murine myoblasts. Hesperidin was able to inhibit cytotoxicity while blocking hydrogen peroxide (H2O2) H2O2-induced DNA damage and apoptosis. Hesperidin also significantly improved the antioxidant capacity of C2C12 cells exposed to H2O2 by suppressing cellular reactive oxygen species production and increasing glutathione level. Additionally, H2O2-induced mitochondrial dysfunction and endoplasmic reticulum (ER) stress were effectively attenuated in the presence of hesperidin. Moreover, hesperidin neutralized H2O2-induced calcium ion (Ca2+) overload in mitochondria and mitigated the expression of cytosolic Ca2+-dependent proteases. These results imply that hesperidin protects against mitochondrial impairment and Ca2+-mediated ER stress by minimizing oxidative stress, thereby suppressing H2O2-induced cytotoxicity in C2C12 myoblasts.
