White adipose tissue (WAT) is a highly dynamic organ and can respond rapidly to alterations in nutrient excess and deprivation, thereby fulfilling its major role in whole body energy homeostasis. Dysfunctional WAT leads to the etiology of a large number of metabolic disorders including the metabolic syndrome and type II diabetes. As the major cell type in WAT, a healthy, highly metabolic responsible adipocyte itself is essential in maintaining adipose tissue functions. However, it has been known that the functions of adipocyte start to fail under many physiological (such as aging) and pathological (obesity, metabolic stress and lipodystrophy) conditions. We are trying to ask the questions about: what are the key factors and mechanisms that control adipocyte functional set limit beyond which WAT fails to function properly? One of our recent studies has shown the capacity of adipocyte ribosome biogenesis which is controlled by ribosomal transcription determines the maximal limit of functional homeostasis.  Further studies for the components and mechanism details of this regulatory machinery will help us not only to understand the importance of the ribosome biogenesis for adipocyte physiology, but also to develop the potential biomarkers and drug targets for diagnosis, prognosis, and therapy in human obesity.
