Cachexia is a complex syndrome that affects multiple compartments and systems in cancer patients. White adipose tissue (WAT) loss is one of the most important clinical "markers" of such disease. Recently, some studies have shown morphological modifications (remodeling) in WAT, characterized by phenotypic changes of white adipocytes that became closer to brown adipocytes profile. This process has been described as browning of WAT. On the other hand, the most part of studies have just addressed some metabolic abnormalities, misevaluating tissue inflammation and, more important, the early events that result in morphological changes induced by cachexia. Moreover, considering the important role of innate immunity receptors as "connecting link" between inflammatory and metabolic events, to our knowledge, few or no studies have evaluated these relationships and their role during the different stages of cachexia. Thus, considering the role of Toll-like receptor 4 (TLR4) in controlling lipolysis, inflammation and consequent adipose tissue remodeling, it is reasonable to postulate that activation of these receptors would have an important role in remodeling of this tissue.Thus, we propose a translational study addressing the mechanisms involved in the early processes of WAT remodeling in cachexia. In addition, the process of metabolic dysfunction and consequent induction of the browning of WAT during the development of cachexia will be adressed in TLR4 knockout mice. In parallel, the same parameters will be evaluated in gastrointestinal cancer patients as well as a set of plasmatic markers and its possible diagnostic application. (AU)
