Adipocytes are highly specialized cells that play a major role in energy homeostasis in vertebrate organisms. Excess adipocyte size or number is a hallmark of obesity, which is currently a global epidemic. Obesity is a major risk factor for the development of type II diabetes (T2DM), cardiovascular disease, and hypertension. Obesity and its related disorders result in dysregulation of the mechanisms that control the expression of metabolic and endocrine related genes in adipocytes. Therefore, understanding adipocyte differentiation is relevant not only for gaining insight into the pathogenesis of metabolic diseases, but also for identifying proteins or pathways which might be appropriate targets for pharmacological interventions. Significant advances towards an understanding of the regulatory processes involved in adipocyte differentiation have largely been made by the identification of transcription factors that contribute to the adipogenic process. It is important to note that the developmental origin of white and brown fat is distinct and different precursor cells are involved in the generation of these different types of adipose tissue (reviewed in Lefterova and Lazar, 2009; Seale et al., 2009). Several transcription factors, notably PPAR gamma, several members of the C/EBP and KLF families, STAT5, and SREBP-1c, have been shown to have significant roles in promoting adipogenesis. More comprehensive reviews on negative and positive regulators of adipogenesis have been published in the past year (reviewed in Christodoulides et al., 2009; Lefterova and Lazar, 2009). Though many proteins are known to negatively regulate adipogenesis, including Wnts, KLFs, the E2F family of transcription factors, CHOP, Delta-interacting protein A, ETO/MTG8, and members of the GATA and forkhead transcription factor families, this review will focus on transcription factors that positively impact the development of white adipose tissue.

Partial inactivation of the Ankyrin repeat domain 26 (Ankrd26) gene causes obesity and diabetes in mice and increases spontaneous and induced adipogenesis in mouse embryonic fibroblasts. However, it is not yet known how the Ankrd26 protein carries out its biological functions. We identified by yeast two-hybrid and immunoprecipitation assays the triple functional domain protein (TRIO), the G protein pathway suppressor 2 (GPS2), the delta-interacting protein A (DIPA) and the hyaluronan-mediated motility receptor (HMMR) as ANKRD26 interacting partners. Adipogenesis of 3T3-L1 cells was increased by selective down-regulation of Ankrd26, Trio, Gps2, Hmmr and Dipa. Furthermore, GPS2 and DIPA, which are normally located in the nucleus, were translocated to the cytoplasm, when the C-terminus of ANKRD26 was introduced into these cells. These findings provide biochemical evidence that ANKRD26, TRIO, GPS2 and HMMR are novel and important regulators of adipogenesis and identify new targets for the modulation of adipogenesis.
