CircRNA regulates the liquid-liquid phase separation of ATG4B, a novel strategy to inhibit cancer metastasis?
Anoikis is a common programmed death for most of detached cells, but cancer cells can obtain anoikis resistance to facilitate their distant metastasis through the circulation system. Researches have indicated that enhanced autophagic flux accounts for the survival of many cancer cells under detached conditions. Targeting ATG4B, the key factor of autophagy progress, can inhibit cancer metastasis in vitro, but ATG4B-deficient mice are susceptible to many serious diseases, which indicates the potential uncontrolled side effects of direct targeting of ATG4B. In our recent research, we confirmed that ATG4B is a novel RNA binding protein in the gastric cancer (GC) cell. It interacts with circSPECC1 which consequently facilitates the liquid-liquid phase separation and ubiquitination of ATG4B. Additionally, the m6A reader ELAVL1 inhibits the expression of circSPECC1 to enhance the expression of ATG4B and anoikis resistance of GC cells. Further, we screened out an FDA-approved compound, lopinavir, to restore circSPECC1 abundance and suppress GC metastasis. In conclusion, our research identified a novel signal pathway (ELAVL1-circSPECC1-ATG4B-autophagy) to facilitate anoikis resistance and metastasis of GC cells and screened out a compound with clinical application potential to block this pathway, providing a novel strategy for the prevention of GC metastasis.

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.
