Hyperoxaluria-induced calcium oxalate (CaOx) deposition is the key factor in kidney stone formation, for which adipose-derived stromal cells (ADSCs) have been used as a therapeutic treatment. Studies revealed that miR-20b-3p is down-regulated in hypercalciuric stone-forming rat kidney. To investigate whether ADSC-derived miR-20b-3p-enriched exosomes protect against kidney stones, an ethylene glycol (EG)-induced hyperoxaluria rat model and an in vitro model of oxalate-induced NRK-52E cells were established to explore the protective mechanism of miR-20b-3p. The results showed that miR-20b-3p levels were decreased following hyperoxaluria in the urine of patients and in kidney tissues from animal models. Furthermore, treatment with miR-20b-3p-enriched exosomes from ADSCs protected EG-induced hyperoxaluria rats, and cell experiments confirmed that co-culture with miR-20b-3p-enriched exosomes alleviated oxalate-induced cell autophagy and the inflammatory response by inhibiting ATG7 and TLR4. In conclusion, ADSC-derived miR-20b-3p-enriched exosomes protected against kidney stones by suppressing autophagy and inflammatory responses.

Global nonprofit biological resource center (BRC) and research organization that provides biological products, technical services and educational programs to private industry, government and academic organizations. Its mission is to acquire, authenticate, preserve, develop and distribute biological materials, information, technology, intellectual property and standards for the advancement and application of scientific knowledge. The primary purpose of ATCC is to use its resources and experience as a BRC to become the world leader in standard biological reference materials management, intellectual property resource management and translational research as applied to biomaterial development, standardization and certification. ATCC characterizes cell lines, bacteria, viruses, fungi and protozoa, as well as develops and evaluates assays and techniques for validating research resources and preserving and distributing biological materials to the public and private sector research communities.
View all literature mentionsSoftware for single-cell flow cytometry analysis. Its functions include management, display, manipulation, analysis and publication of the data stream produced by flow and mass cytometers.
View all literature mentionsWeb tool to predict biological targets of miRNAs by searching for presence of conserved 8mer, 7mer and 6mer sites that match seed region of each miRNA. Nonconserved sites are also predicted and sites with mismatches in seed region that are compensated by conserved 3' pairing. Used to search for predicted microRNA targets in mammals.
