Adipogenesis is the process of cell differentiation by which mesenchymal stem cells (MSCs) become adipocytes, the process is tightly regulated by many factors. A useful approach to improve our understanding is to consider these regulatory processes in the context of networks. We propose here it is necessary to provide an information center that is quickly and easily accessible to researchers in this field. In the present study, we developed a publicly available database and Web interface that serves as a resource for adipogenesis research. In ARN, nodes (genes and microRNAs) were collected using a text mining procedure followed by manual review and annotation by experts of this field.
