Lipid droplets (LDs) are dynamic organelles that collect, store, and supply lipids [1]. LDs have a central role in the exchange of lipids occurring between the cell and the environment and provide cells with substrates for energy metabolism, membrane synthesis, and production of lipid-derived molecules such as lipoproteins or hormones. However, lipid-derived metabolites also cause progressive l...
OBJECTIVE Type 2 diabetes is a complex disease that is accompanied by elevated levels of nonesterified fatty acids (NEFAs), which contribute to β-cell dysfunction and β-cell loss, referred to as lipotoxicity. Experimental evidence suggests that oxidative stress is involved in lipotoxicity. In this study, we analyzed the molecular mechanisms of reactive oxygen species-mediated lipotoxicity in in...
Anomalous inflammatory responses triggered by the metabolic syndrome cause renal injury. This discovery links renal lipid accumulation with lipotoxicity to inflammation and may explain the insidious fibrosis and cellular decay characteristic of nephropathy in the metabolic syndrome. However, it is not clear whether control of inflammation protects the kidney independently of lipid accumulation,...
Increasing maternal obesity is a challenge that has an impact on all aspects of female reproduction. Lean and obese pregnant women gain similar fat mass, but lean women store fat in the lower-body compartment and obese women in central compartments. In the non-pregnant, central storage of fat is associated with adipocyte hypertrophy and represents a failure to adequately store excess fatty acid...
Background: Co-supplementation of unsaturated fatty acids (FAs) with saturated FAs may decrease the adverse effects of saturated FA-induced lipotoxicity. The objective of the present study was to evaluate the effect of palmitoleic acid (unsaturated fatty acid) on palmitic acid (saturated fatty acid) induced lipotoxicity criteria in the primary culture of adult rat cardiomyocytes. Methods: Ce...
Lipotoxicity is a metabolic stress response implicated in the pathogenesis of diabetes complications and has been shown to involve lipid-induced oxidative stress. To elucidate the molecular mechanisms of lipotoxicity, we used retroviral promoter trap mutagenesis to isolate a cell line that is resistant to lipotoxic and oxidative stress. We show that loss of three box C/D small nucleolar RNAs (s...
Exposure to toxic levels of fatty acids (lipotoxicity) leads cell damage and death is involved in the pathogenesis metabolic syndrome. Since consequences lipotoxicity are still poorly understood, we studied bioenergetic effects saturated acid palmitate, quantifying changes mitochondrial morphology, real-time oxygen consumption, ATP production sources, extracellular acidification hepatoma cells....
