  • Background of ExMdb

    E xosomes are a nano-sized vesicle structure derived from cells, which can be derived from normal cells and tumor cells of the body, and are distributed in various body fluids such as blood, saliva, urine, breast milk and so on. It contain an abundant product of different RNA species that can regulate the behavior of recipient cells and can be used as circulating biomarkers for diseases. In recent years, due to the constant understanding and study of exosomes, research on exosomes has become a hot spot. Therefore, the collection of exosome data will be crucial for its next research, prevention and diagnosis.In this study, we established ExMdb, a manually curated database which aims at providing data support for the study of exosome RNA. ExMdb provides a user-friendly interface for convenient browsing, retrieval and downloading of dataset. A submission page is also included to allow researchers to submit newly exosome RNA to cancer data.
