As fatty acid synthesis occurs in the cytosol, we monitored the cytosolic content of NADPH using the genetically encoded fluorescent iNAP sensor21,22. Figure 2a, b show that the NADPH level decreased by about 30% in FASN-overexpressing adipocytes. We also used a HYPER sensor23 to monitor cellu...
Serum free fatty acid (FFA) flux is decreased in shock. The question arose whether the limited availability of FFA would result in a fuel deficit in organs containing no stored lipid and also in the slower turnover of organ phospholipids. The fasting dog's lung, stomach, heart, and liver ...
Maternal factors such as diet, obesity, endocrine, inflammation can modulate the expression and activity of the placental fatty acid transport activity and thereby impact feto-placental growth and development. In this review, we discuss the maternal dietary fatty acids, and placental transport and ...

Subjects with metabolic syndrome (MetS) commonly have atrial remodeling, which indicates a risk for atrial fibrillation. This study determined MetS-related changes in lipid components in very-low-density lipoprotein (VLDL), which has been shown to cause
The actual location of the double bond in the fatty acid chain affects its metabolism such that the structure and function of omega-3–derived eicosanoids differ from those derived from omega-6 fatty acids (eg, arachidonic acid). For example, omega-3–derived eicosanoids tend to decrease blood...
of the mechanisms of action through which omega-3 and omega-6 PUFA modulate the immune-inflammatory response and summarizes the current body of evidence regarding the clinical and pharmacoeconomic benefits of intravenous n-3 fatty acid-containing lipid emulsions in patients requiring parenteral nutrition...
NAFLD: non-alcoholic fatty liver disease; FFA: free fatty acid; VLDL: Very low-density lipoprotein; DNL: de novo lipogenesis; ER: endoplasmic reticulum; ROS: reactive oxygen species; TNF-α: tumor necrosis factor-α; NF-KB: nuclear factor-KB, IL: Interleukin; JNK: c-jun N terminal ...
fatty acid uptake (either by nutrients or from adipose tissue), fatty acid synthesis, fatty acid oxidation, or the export of lipids from the liver through effects on apolipoprotein B and microsomal transport protein [37]. Zeroing on lipid synthesis, sterol regulatory element-binding protein (SREBP...
Fatty-acid synthase has been purified to homogeneity from human liver by a 3-step procedure including protamine sulfate/ammonium sulfate fractionation, affinity chromatography on 2',5'-ADP-Sepharose 4B and gel filtration on Sephacryl S-300. Both the human and rat fatty-acid synthase had similar ...
