Abstract

The Metabolic Syndrome affects 25% of the adult population, emerging as one of the largest public health concerns worldwide, being Obesity and insulin resistance extremely relevant in this context. Caloric restriction and physical exercise appear as important interventions to treat metabolic diseases, however, the cellular and molecular components that participate in the beneficial effects of these interventions are not completely elucidated. It is known that adipose tissue microRNAs (miRNAs) are regulated under these conditions and that miR-203-3p is articularly decreased in Obesity and increased in response to physical exercise and caloric restriction. Preliminary data from our group point to miR203-3p as a candidate to mediate metabolic adaptation under energetic stress conditions. However, this miRNA is barely explored in the context of metabolism and studies are required to characterize its functions in vivo. Thus, we propose to generate adipocyte-specific mir203 knockout mice seeking to understand the function of miR-203-3p in adipose tissue in vivo, its role in the metabolic adaptation to caloric restriction and physical exercise, as well as its possible therapeutic role in metabolic disorders. In parallel, we will evaluate, in vivo and in vitro, a possible role for adipose tissue miR-203-3p in intertissue communication. (AU)
