Alterations of cardiac membrane functions can be induced by lipid rich diets. As to this the influence of the admixture of cholesterol (group Ch) and rape oil (group R) to standard food during 12 weeks on the course of the isometric twitch of rabbit papillary muscles in normoxia and hypoxia was

In Saccharomyces cerevisiae, OLE1 encodes a delta9 fatty acid desaturase, an enzyme that plays a critical role in maintaining the correct ratio of saturated to monounsaturated fatty acids in the cell membrane. Previous studies have demonstrated that (i) OLE1 expression is repressed by unsaturated

Unsaturated fatty acids as high-affinity ligands of the C-terminal Per-ARNT-Sim domain from the Hypoxia-inducible factor 3α.

Hypoxia-inducible transcription factors (HIF) form heterodimeric complexes that mediate cell responses to hypoxia. The oxygen-dependent stability and activity of the HIF-α subunits is traditionally associated to post-translational modifications such as hydroxylation, acetylation, ubiquitination, and

The metabolism of lipids, like that of other components, was adversely and strongly affected when rice (Oryza sativa L.) coleoptiles were grown anaerobically. In aerobic coleoptiles, the amounts of total fatty acid, phospholipid, and total lipid per coleoptile increased by 2.5- to 3-fold between

BACKGROUND In diverse organisms, adaptation to low oxygen (hypoxia) is mediated through complex gene expression changes that can, in part, be mimicked by exposure to metals such as cobalt. Although much is known about the transcriptional response to hypoxia and cobalt, little is known about the

Influence of Serum and Hypoxia on Incorporation of [(14)C]-D-Glucose or [(14)C]-L-Glutamine into Lipids and Lactate in Murine Glioblastoma Cells.

Glucose and glutamine are essential energy metabolites for brain tumor growth and survival under both normoxic and hypoxic conditions. Both metabolites can contribute their carbons to lipid biosynthesis. We used uniformly labeled [(14)C]-U-D-glucose and [(14)C]-U-L-glutamine to examine the profile

The influence of acute normobaric hypoxia on total pool of human plasma fatty acids was studied in experiment (respiration of hypoxic gas mixture containing 8% of O2, during 25 min). Health status of participants-volunteers and the hypoxia intensity were monitored with a complex of

The effects of long-term treatment with eicosapentaenoic acid and docosahexaenoic acid on hypoxia/rexoygenation injury of isolated cardiac cells in adult rats.

N-3 polyunsaturated fatty acids have been epidemiologically demonstrated to decrease the incidence of ischaemic heart disease. The present study was undertaken to examine the effects of long-term treatment with eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on hypoxia/reoxygenation

Chronic cellular hypoxia as the prime cause of cancer: what is the de-oxygenating role of adulterated and improper ratios of polyunsaturated fatty acids when incorporated into cell membranes?

With the exception of melanoma and non-Hodgkin's lymphoma, the incidence of cancer has peaked in the last several years, but rates and mortality are still high. Moreover, despite 50 years of intensive cancer research increasingly focused on genetic causes, no single unifying cause for cancer has

[The effect of acute hypoxia on the fatty acid composition and lipid peroxidation of the liver microsomal membranes and blood plasma in rats with different resistances to oxygen deficiency].

The experiments in rats showed the changes in the fatty acids composition of lipids of hepatic microsomal membranes and lipids of blood plasma after acute hypobaric hypoxia to depend on individual resistance of animals to oxygen deficiency. In highly resistant rats the content of unsaturated fatty

The paper deals with the content and composition of brain gangliosides under two forms of acute hypoxia, hypoxic and hemic ones which develop as a result of the effect of gradually increasing concentration of CO2, decreasing concentration of O2 and external cooling (1st form) and parenteral

OBJECTIVE Peroxidation of membrane lipids, altering cell integrity and function, plays an important part in the onset and development of cardiac damage following ischemia and reperfusion. Cells maintain their membrane lipid homeostasis by substituting peroxidized lipids with new polyunsaturated

OBJECTIVE

Inflammatory activation changes the mitochondrial function of macrophages from oxidative phosphorylation to reactive oxygen species production, which may promote necrotic core formation in atherosclerotic lesions. In hypoxic and cancer cells, HIF-1α (hypoxia-inducible

Agrobacterium tumefaciens-derived crown galls of Arabidopsis (Arabidopsis thaliana) contain elevated levels of unsaturated fatty acids and strongly express two fatty acid desaturase genes, ω3 FATTY ACID DESATURASE3 (FAD3) and STEAROYL-ACYL CARRIER PROTEIN Δ9-DESATURASE6 (SAD6). The fad3-2 mutant
