Incidence and prevalence of owerweight and obesity have greatly increased over the past three decades in almost all countries around the world. This phenomenon is not easily explained by lifestyle changes in populations with very different initial habits. This has led to consider the influence of other factors, the so-called endocrine disruptors, and more specifically obesogens. This study revi...
Building on the new synthesis of information introduced at the Wingspread Conference in 1991 (Colborn and Clement, 1992) participants helped frame the concept of “endocrine disruption”. The core observation upon which this concept was based was that some exogenous compounds of both natural and synthetic origin can interact with hormonal systems by one of several mechanisms, including mimicking ...
Nuclear receptors play important roles in the maintenance of the endocrine system, regulation of organ differentiation, and fetal development. Endocrine disruptors exert their adverse effects by disrupting the endocrine system via various mechanisms. To assess the effects of endocrine disruptors on nuclear receptors, we developed a high-throughput method for identifying activators of nuclear re...
A wide variety of chemicals are used in pharmaceuticals. Most of these are already under thorough control for endocrine activity. The main causal agents recognized for endocrine disruption from sewage are substances used in medicine (sex hormones, glucocorticoids, and others), natural substances (estrone and 17β-estradiol), and synthetic estrogens (e.g., 17α-ethinylestradiol). Similar substance...
Many compounds in the environment capable of acting as endocrine disruptors have been assayed for their developmental effects on morphogenesis; however, few studies have addressed how such xenobiotics affect physiology. In the current study we examine the effects of three endocrine-disrupting compounds, chlordane, trans-nonachlor, and the polychlorinated biphenyl (PCB) mixture Aroclor 1242, on ...
