I Björkhem et al.
Journal of lipid research, 42(3), 366-371 (2001-03-20)
Infants with the cholesterol synthesis defect Smith- Lemli-Opitz syndrome (SLO) have reduced activity of the enzyme 7-dehydrocholesterol-7-reductase and accumulate 7-dehydrocholesterol, with the highest concentration in the brain. As a result of the generally reduced content of cholesterol, plasma levels of...
Donato A Rivas et al.
American journal of physiology. Regulatory, integrative and comparative physiology, 310(7), R561-R569 (2016-01-15)
The loss of skeletal muscle mass is observed in many pathophysiological conditions, including aging and obesity. The loss of muscle mass and function with aging is defined as sarcopenia and is characterized by a mismatch between skeletal muscle protein synthesis...
Ngoc Vu et al.
Analytical and bioanalytical chemistry, 411(23), 5937-5949 (2019-07-08)
Dysregulated lipid species are linked to various disease pathologies and implicated as potential biomarkers for type 1 diabetes (T1D). However, it is challenging to comprehensively profile the blood specimen lipidome with full structural details of every lipid molecule. The commonly...
Delphine Milhas et al.
FEBS letters, 584(9), 1887-1894 (2009-10-28)
The plasma membrane (PM) is a major resource for production of bioactive lipids and contains a large proportion of the cellular sphingomyelin (SM) content. Consequently, the regulation of SM levels at the PM by enzymes such as sphingomyelinase (SMase) and...
Ulrike Bruning et al.
Cell metabolism, 28(6), 866-880 (2018-08-28)
The role of fatty acid synthesis in endothelial cells (ECs) remains incompletely characterized. We report that fatty acid synthase knockdown (FASNKD) in ECs impedes vessel sprouting by reducing proliferation. Endothelial loss of FASN impaired angiogenesis in vivo, while FASN blockade reduced...
Maria Tikhonenko et al.
PloS one, 8(1), e55177-e55177 (2013-02-06)
The vasodegenerative phase of diabetic retinopathy is characterized by not only retinal vascular degeneration but also inadequate vascular repair due to compromised bone marrow derived endothelial progenitor cells (EPCs). We propose that n-3 polyunsaturated fatty acid (PUFA) deficiency in diabetes...
Ali Assi et al.
Analytical and bioanalytical chemistry, 412(3), 777-793 (2019-12-21)
Stratum corneum lipids are responsible for the skin's barrier function. They are the final product of epidermis lipid biosynthesis. During this process, lipids evolve from simple to complex structures in three main levels respectively (stratum basal level, stratum granulosum level...
Brandt Bertrand et al.
Biochimica et biophysica acta. Biomembranes, 1862(2), 183105-183105 (2019-11-05)
The aim of this study was to investigate the factors that govern the activity and selectivity of two potent antimicrobial peptides (AMPs) using lipid membrane models of bacterial, erythrocyte and fungal cells. These models were used in calcein liposome leakage...
Nesli-Ece Sen et al.
International journal of molecular sciences, 20(23) (2019-11-27)
Ataxin-2 (human gene symbol ATXN2) acts during stress responses, modulating mRNA translation and nutrient metabolism. Ataxin-2 knockout mice exhibit progressive obesity, dyslipidemia, and insulin resistance. Conversely, the progressive ATXN2 gain of function due to the fact of polyglutamine (polyQ) expansions...
