MetabolomicsOxygen-induced pathological angiogenesis promotes intense lipid synthesis and remodeling in the retina

The retina is a notable tissue with high metabolic needs which relies on specialized vascular networks to protect the neural retina while maintaining constant supplies of oxygen, nutrients and dietary essential fatty acids. Here we analyzed the lipidome of the mouse retina under healthy and patho...

MetabolomicsLactobacillus plantarum MR1 alleviates high-carbohydrate diet-induced oxidative stress and liver lipid deposition via upregulating uridine synthesis
The overconsumption of carbohydrates induces oxidative stress and lipid accumulation in the liver, which can be alleviated by modulation of intestinal microbiota; however, the underlying mechanism remains unclear. Here, we demonstrated that a strain affiliated with Lactobacillus plantarum (de...

MetabolomicsFatty acid synthesis in colorectal cancer: characterization of lipid metabolism in serum, tumour, and normal host tissues
The objective of the experiment was to compare serum fatty acid metabolite abundance between individuals with varying clinical stages of colorectal cancer (stage I-IV) and age-and-gender matched disease-free controls. Fatty acid metabolite abundance was compared between locoregional (stage I-III) an...

MetabolomicsPatA mediates biofilm formation and drugs resistance through regulating the synthesis of glycolipids and lipids in mycobacterium PatA mediates a novel mycolic acid synthesis pathway and regulates biofilm formation in mycobacterium
Glycolipids and lipids are prominent components of bacterial cell wall that play critical roles not only in maintaining the biofilm formation but also in resistance to environmental stress. PatA is an essential membrane associated acyltransferase involved in the biosynthesis of phosphatidyl-myo-inos...

MetabolomicsHERPES SIMPLEX VIRUS TYPE 1 IMPAIRS DENDRITIC CELL FUNCTION BY REMODELLING NEUTRAL LIPID METABOLISM AND INDUCING LIPID DROPLET ACCUMULATION
Herpes simplex virus type 1 (HSV-1) infects dendritic cells (DCs), professional antigen-presenting cells that initiate and regulate host antiviral responses. HSV-1 infects DCs limiting their maturation, migration to draining lymph nodes and T cell activation capacity, ultimately promotes their apopt...

MetabolomicsLipidomic analysis of lipid droplets from murine hepatocytes reveals distinct signatures for nutritional stress
Liver steatosis can be induced by fasting or high-fat diet. We investigated by lipidomic analysis whether such metabolic states are reflected in the lipidome of hepatocyte lipid droplets (LDs) from mice fed normal chow diet (FED), fasted (FAS), or fed a high-fat diet (HFD). LC-MS/MS at levels of lip...

MetabolomicsThe lipid-metabolism enzyme ECI2 reduces neutrophil extracellular traps formation for colorectal cancer suppression
Abnormalities in ether lipid metabolism as well as the formation of neutrophil extracellular traps have recently been recognized as detrimental factors affecting tumorigenesis and progression. However, the role of abnormal ether lipid metabolism in colorectal cancer (CRC) evolution has not been repo...

MetabolomicsLsr2, a novel cyclic di-GMP receptor, regulate the synthesis of keto-mycolic acid and control biofilm formation in mycobacteria

Cyclic di-GMP (c-di-GMP) is a well-known second messenger that plays a key role in many physiological processes in bacteria. The synthesis of lipids is essential for bacterial biofilm formation. However, whether c-di-GMP signaling modulates the synthesis of lipid and further regulates biofilm for...

MetabolomicsInterorganelle lipid flux revealed by enzymatic mass tagging in vivo
The distinct activities of cellular organelles are dependent on the proper function of their membranes. Coordinated membrane biogenesis of the different organelles necessitates interorganelle transport of lipids from their site of synthesis to their destination membranes. Several proteins and traffi...
