Resveratrol (trans-3,4’,-5-trihydroxystilebene), a calorie restriction mimetic, exerts anti-aging, anti-oxidative and immunomodulatory activities. However, both aging and resveratrol have been shown to inhibit the differentiation of preadipocytes. Since relatively high doses of resveratrol were employed previously, we reexamined the dosedependent effects of resveratrol on 3T3-L1 preadipocyte di...

The nuclear hormone receptor, REV-ERB, plays an essential role in adipogenesis. Rev-erbalpha expression is induced in 3T3-L1 cells during adipogenesis, and overexpression of this receptor leads to expression of adipogenic genes. We recently demonstrated that the porphyrin heme functions as a ligand for REV-ERB, and binding of heme is required for the receptor's activity. We therefore hypothesiz...

Osteoporosis is a frequently occurring bone remodeling disorder worldwide with one characteristic being decreasing mineral density and predisposition to fracture, which diminishes patients’ quality of life. Several studies showed that imbalance between the osteogenesis adipogenesis marrow mesenchymal stem cells (BMSCs) took part in development osteoporosis. In previous study, we found MIR22HG r...

Background: Natural products have gained importance recently for the treatment of obesity and its complications, partly because of the side effects of modern drugs.Hence, we aimed to study and compare the effect of varying concentrations of Momordicacharantiaon adipogenesis and adipolysis using 3T3-L1 pre-adipocyte cell lines. Methods: 3T3-L1 pre-adipocytes were procured from the National Ce...

Adipogenesis, the conversion of precursor cells into adipocytes, is associated with obesity and is mediated by glucocorticoids acting via hitherto poorly characterized mechanisms. Dexras1 is a small G protein of the Ras family discovered on the basis of its marked induction by the synthetic glucocorticoid dexamethasone. We show that Dexras1 mediates adipogenesis and diet-induced obesity. Adipog...

The prevalence of obesity has led to a surge of interest in understanding the detailed mechanisms underlying adipocyte development. Many protein-coding genes, mRNAs, and microRNAs have been implicated in adipocyte development, but the global expression patterns and functional contributions of long noncoding RNA (lncRNA) during adipogenesis have not been explored. Here we profiled the transcript...

Bone loss occuring with unloading is associated with decreased osteoblastogenesis and increased bone marrow adipogenesis, resulting in bone loss and decreased bone formation. Here, we review the present knowledge on the role of PPARgamma in the control of osteoblastogenesis and bone mass in skeletal unloading. We showed that PPARgamma positively promotes adipogenesis and negatively regulates os...

The past decade has witnessed a sudden surge in the obesity prevalence worldwide. Obesity has been linked to several chronic metabolic disorders including diabetes, hyperlipidemia and atherosclerosis. Due to this there is an immense interest in understanding the intricate aspects of adipogenesis, specifically pertaining to the study of the mechanisms through which various signaling pathways reg...

Adipocytes play a key role in energy homeostasis and several cytokines have been shown to regulate adipogenesis. While the interleukin (IL)-6 family of cytokines was previously reported to be involved in adipogenesis, roles of this family in adipogenesis and their mechanisms of action are not fully understood. Here we show that among the IL-6 family, oncostatin M (OSM) most strongly inhibits ad...

OBJECTIVE We investigated the regulation and involvement of microRNAs (miRNAs) in fat cell development and obesity. RESEARCH DESIGN AND METHODS Using miRNA microarrays, we profiled the expression of >370 miRNAs during adipogenesis of preadipocyte 3T3-L1 cells and adipocytes from leptin deficient ob/ob and diet-induced obese mice. Changes in key miRNAs were validated by RT-PCR. We further asse...
