Obesity is characterized by increased adipose tissue mass and has been associated with a strong predisposition towards metabolic diseases and cancer.

Adipogenesis

Obesity is now a widespread disorder, and its prevalence has become a critical concern worldwide, due to its association with common co-morbidities like cancer, cardiovascular diseases and diabetes. Adipose tissue is an endocrine organ and therefore plays a critical role in the survival of an individual, but its dysfunction or excess is directly linked to obesity. The journey from multipotent mesenchymal stem cells to the formation of mature adipocytes is a well-orchestrated program which requires the expression of several genes, their transcriptional factors, and signaling intermediates from numerous pathways. Understanding all the intricacies of adipogenesis is vital if we are to counter the current epidemic of obesity because the limited understanding of these intricacies is the main barrier to the development of potent therapeutic strategies against obesity. Since AMPK promotes the development of brown adipose tissue over that of white adipose tissue, special attention has been given to its role in adipose tissue development in recent years. In this review, we describe the molecular mechanisms involved in adipogenesis, the role of signaling pathways and the substantial role of activated AMPK in the inhibition of adiposity, concluding with observations which will support the development of novel chemotherapies against obesity epidemics. Obesity is an increasingly prevalent disorder around the globe promoted by genetic, nutritional, and environmental factors. Energy imbalance — excessive consumption of calories compared to utilization is the key driving force of obesity. Obesity is a multifactorial chronic disease, linked to other disorders including cancer, insulin resistance, cardiovascular diseases and type-2 diabetes Cohen et al. There are many factors which contribute to obesity such as sedentary lifestyle, high calorific intake, depression, and various social and monetary issues, but they have a single common result: the accumulation of fats in mature adipocytes of white adipose tissue WAT : obesity is characterized by increase in the mass of adipose tissue Ghaben and Scherer, Improved and holistic knowledge of the processes governing adipogenesis is required if we are to counter the burgeoning epidemic Rosen and MacDougald, Adipose tissue plays an important proper role in the body. Obesity is diagnosed either on the amount of WAT or the number of mature white adipocytes in WAT Park, , rather than simply by body weight. The expansion of adipose depots can be driven either by the increase in the number hyperplasia or size hypertrophy of adipocytes Ghaben and Scherer,

Federal government websites often end in. The site is secure. The formation of adipocytes during embryogenesis has been largely understudied. Adipogenesis consists of two phases, namely commitment and terminal differentiation. This review discusses the role of signalling pathways, epigenetic modifiers, and transcription factors in preadipocyte commitment and differentiation into mature adipocytes, as well as limitations in our understanding of these processes.

Dysfunction of adipocytes and adipose tissue is a primary defect in obesity and obesity-associated metabolic diseases.

The importance of UCP1 was shown in knockout mice, whereby UCP1-deficient mice were unable to survive long-term exposure to cold Golozoubova et al. Transcriptional control of brown adipocyte development and physiological function of mice and men. Van Kruijsdijk, R. Tools Tools. Oral, E. Lefterova, M. MiR also inhibits osteogenesis, but instead of targeting RUNX2, it targets distal-less homeobox 5 Dlx5 , another pro-osteogenic transcription factor [ ]. Other evidence suggests that the presence of anti-inflammatory macrophages in BAT plays a role in heat production Nguyen et al. Lipid Res. Lotta, L. Zoico, E.

Another lineage tracing study using a Myf5-Cre knock-in allele, showed that interscapular BAT and skeletal muscle are positive for Myf5 while inguinal and perigonadal WAT are negative for Myf5 [ 24 ]. Estrogen deficiency, obesity, and skeletal abnormalities in follicle-stimulating hormone receptor knockout FORKO female mice. Herrero-Martin, G.

ADD1: A novel helix-loop-helix transcription factor associated with adipocyte determination and differentiation. Komiya Y. Tomlinson, J. Diabetes 62, — Several molecular factors including signalling pathways, epigenetic modifiers and other transcription factors regulate the expression of these two transcription factors during adipogenesis Figure 1 , which together, regulate the expression of key adipogenic genes that characterize the adipocyte phenotype. Activation of the thermogenic system in humans, either in WAT or BAT, should correlate well with an increase of energy expenditure. However, it is unlikely that STAT1 plays a critical role in adipocyte development, because STAT1-knockout mice do not have any apparent body weight abnormalities Meraz et al.
