Macrolide antibiotics activate the integrated stress response and promote tumor proliferation.
Macrolide antibiotics are widely used antibacterial agents that are associated with autophagy inhibition. This study aimed to investigate the association between macrolide antibiotics and malignant tumors, as well as the effect on autophagy, reactive oxygen species (ROS) accumulation and integrated stress response (ISR). The meta-analysis indicated a modestly higher risk of cancer in macrolide antibiotic ever-users compared to non-users. Further experiments showed that macrolides block autophagic flux by inhibiting lysosomal acidification. Additionally, azithromycin, a representative macrolide antibiotic, induced the accumulation of ROS, and stimulated the ISR and the activation of transcription factor EB (TFEB) and TFE3 in a ROS-dependent manner. Finally, animal experiments confirmed that azithromycin promoted tumor progression in vivo, which could be receded by N-acetylcysteine, an inhibitor of ROS and ISR. Overall, this study reveals the potential role of macrolide antibiotics in malignant progression and highlights the need for further investigation into their effects.

期刊介绍:
Cell Stress is an open-access, peer-reviewed journal that is dedicated to publishing highly relevant research in the field of cellular pathology. The journal focuses on advancing our understanding of the molecular, mechanistic, phenotypic, and other critical aspects that underpin cellular dysfunction and disease. It specifically aims to foster cell biology research that is applicable to a range of significant human diseases, including neurodegenerative disorders, myopathies, mitochondriopathies, infectious diseases, cancer, and pathological aging.
The scope of Cell Stress is broad, welcoming submissions that represent a spectrum of research from fundamental to translational and clinical studies. The journal is a valuable resource for scientists, educators, and policymakers worldwide, as well as for any individual with an interest in cellular pathology. It serves as a platform for the dissemination of research findings that are instrumental in the investigation, classification, diagnosis, and therapeutic management of major diseases. By being open-access, Cell Stress ensures that its content is freely available to a global audience, thereby promoting international scientific collaboration and accelerating the exchange of knowledge within the research community.
