TLR4 activation and the induction of endoplasmic reticulum stress (ERS) are two of the most important mechanisms connecting excessive dietary fat with insulin resistance. TLR4 activation is a primary event in the induction of cellular stress that contributes to increased inflammatory gene expression in metabolic diseases. However, the mechanisms linking these molecular events are unknown. The chaperones GRP78 and GRP94 play an important role during the assembly of newly transl...

Introduction: High circulating levels of some but not all unsaturated fatty acids (UFAs) can be related with reduced insulin sensitivity and glucose uptake in skeletal muscle. The real mechanisms by which UFAs impair the insulin sensitivity need to be clarified; nevertheless the UFA’s effects in the regulation of activity and/or expression of some transcriptional factors such as, nuclear factor κB (NFκB), hypoxia inducible factor-1a (HIF-1a), peroxisome prolifer...
