De novo lipogenesis (DNL) is a metabolic pathway for the endogenous synthesis of triglycerides and other lipids from dietary starch, sugar, and protein [1,2]. Palmitic acid (16:0) is the major fatty acid product of DNL and can be elongated to stearic acid (18:0) and desaturated to form palmitoleic acid (16:1n7) and from stearic acid to oleic acid (18:1n9).

The inhibition of miR-122 protects hepatocytes from lipid metabolic disorders such as NAFLD and suppresses lipogenesis via elevating Sirt1 and activating the AMPK pathway. These data support miR-122 as a promising biomarker and drug target for NAFLD. Based upon the genome information, a lipogenesis pathway was constructed, which mapped the utilization of glucose, generation of acetyl-CoA and NADPH, and biosynthesis of fatty acids, glycerolipids, glycerophospholipids, sphingolipids and sterols (Figure 5). M. alpina can grow on glucose as the single carbon source.

The pentose phosphate pathway (also called the phosphogluconate pathway and the hexose monophosphate shunt) is a metabolic pathway parallel to glycolysis. It generates NADPH and pentoses (5-carbon sugars) as well as ribose 5-phosphate, a precursor for the synthesis of nucleotides. Lipogenesis is induced in cancer cells by EGF through activation of the HER2/neu receptor and the PI3-kinase/Akt pathway (24–26) targeting SREBP-1 (24,27). As AMPK inhibits ACC by phosphorylation, its inactivation diminishes lipid supply and blocks cell cycle decreasing cell division and tumor growth .

Further, BME treatment significantly reduced phosphatidylcholine, phosphatidylethanolamine, and plasmenylethanolamine, and reduced iPLA2 activity. Objective To examine the associations of fatty acids in the de novo lipogenesis (DNL) pathway, specifically myristic acid (14:0), palmitic acid (16:0), cis- palmitoleic acid (c16:1 n-7), cis- myristoleic acid (c14:1n5), stearic acid (18:0) and cis- oleic acid (c18:1 n-9), with 5-year risk of type 2 diabetes.

The solid lines and shaded area represent the central risk estimate and 95% CI, respectively, for each fatty acid. The de novo lipogenesis is a metabolic pathway of fatty acid synthesis from excessive energy intake (e.g., carbohydrates) and multiple regulatory genes are involved in this pathway. For example, Acaca (also known as acetyl-CoA carboxylase-1; encoded by the Acaca ) is a key enzyme of de novo lipogenesis … Compared to a wild-type strain, the novel lipogenesis pathway in our strain was designed to compensate for this problem due to abolishment of ethanol fermentation.

Lipogenesis. When glucose levels are plentiful, the excess acetyl CoA generated by glycolysis can be converted into fatty acids, triglycerides, cholesterol, steroids, and bile salts. This process, called lipogenesis, creates lipids (fat) from the acetyl CoA and takes place in the cytoplasm of adipocytes (fat cells) and hepatocytes (liver cells). When you eat more glucose or carbohydrates than your body needs, your system uses acetyl CoA to turn the excess into fat. Lipogenesis.

Previous studies have demonstrated that SREBP-1c activation and lipogenesis requires the mTOR/S6K1 pathway [ 17] and that SREBP-1c is a target of LXRα. Hence, the expression of mTOR, S6K1 and LXRα was also detected.

In the opposite to fatty acid degradation, which is located within the mitochondria, de novo synthesis of fatty acids takes place within the cytosol. The precursor of fatty acid synthesis is acetyl-CoA, that is transported out of the mitochondria into the cytosol via the citrate shuttle. The NADPH necessary for fatty acid synthesis derives from the conversions of malic enzyme, glucose 6-P dehydrogenase, gluconate 6-P dehydrogenase and Lipogenesis is an important metabolic pathway in the pathogenesis of malignancies, especially HCC. Induction of oxidative stress and imbalance in adipokines that are observed in obesity are significantly associated with HCC. Lipogenesis is defined as the synthesis of fatty acids from nonlipid precursors. It is a pathway for metabolism of excess carbohydrate and is activated by high carbohydrate availability. Lipogenesis: the pathway of fatty acid synthesis. The key regulating enzyme of lipogenesis is acetyl-CoA carboxylase, which catalyzes the synthesis of malonyl-CoA from acetyl-CoA and CO 2. The activity of acetyl-CoA carboxylase depends on its phosphorylation status and its interaction with the antioncogen BRAC 1.
