MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Bisphenol A (BPA) is a compound considered to be a potential environmental hazard and an endocrine disruptor. We have found an association between exposure to BPA at levels that are considered safe by Health Canada and the EPA early in life, and the development of obesity. In addition, we found that this propensity to develop obesity is due to under development of the hypothalamic projection field of POMC neurons, a set of neurons that regulate satiety and stimulate metabolic rate.
In this paper we replicate those findings and also show that this abnormal development is due to BPA altering the secretion of the hormone leptin at critical times where this hormone is important for the post-natal development of these POMC neurons.
