Induction of Mitochondrial Dysfunction and Oxidative Damage by Antibiotic Drug Doxycycline Enhances the Responsiveness of Glioblastoma to Chemotherapy
This 2017 study investigates the effects of doxycycline, an FDA-approved antibiotic, on glioblastoma cells. Doxycycline induces mitochondrial dysfunction, leading to decreased mitochondrial membrane potential, reduced ATP production, and increased reactive oxygen species (ROS) levels. These changes result in oxidative damage to DNA, proteins, and lipids, causing cell cycle arrest and
