Alteration of lipid fatty acid profile and cationic fluxes in ventricular cardiomyocytes from omega3-depleted rats.

The bolus intravenous injection of a medium-chain triglyceride:fish oil emulsion was recently found to increase within 60 min the cell phospholipid content in long-chain polyunsaturated omega3 fatty acids and, hence, proposed as a potential tool to prevent cardiac arrhythmia in subjects with a decreased dietary intake of such fatty acids. In the present study, ventricular cardiomyocytes from second generation rats depleted in omega3 fatty acids were found to display the same changes in the phospholipid fatty acid pattern as that previously documented in the cardiac muscle and endothelium of such rats, altered 86Rb and 45Ca fluxes with emphasis on a decrease in both K+ inflow and K+ content and an increase in both Ca2+ inflow and content. The alteration of K+ inflow could not be attributed to a decrease in ouabain-sensitive Na+,K+-ATPase activity as measured in cell homogenates.

Perturbation of phospholipid and triacylglycerol fatty acid positional location in the heart of rats depleted of n-3 long-chain polyunsaturates.

Rats depleted of long-chain polyunsaturated n-3 fatty acids (n-3-D) display several features of the metabolic syndrome, including obesity, liver steatosis, insulin resistance, hypertension, and cardiac hypertrophy. In this study, the heart phospholipid (PL) and triacylglycerol (TG) fatty acid content and pattern were compared between female control rats (C) and n-3-D rats. The sole n-3 fatty acids found in n-3-D rats, C22:5(n-3) and C22:6(n-3), were 10 to 20 times lower than in C.

Fatty acid profile of plasma and liver lipids in mice depleted in long-chain polyunsaturated (n-3) fatty acids.

Considering the numerous features of the metabolic syndrome found in rats depleted in long-chain polyunsaturated (n-3) fatty acids and in the perspective of further work conducted in (n-3)-depleted mice, the fatty acid profile of plasma and liver lipids was assessed in both male and female control and second-generation (n-3)-depleted mice. In addition to gender differences, the major alteration found in the (n-3)-depleted animals consisted in the expected severe depletion of plasma triacylglycerols and phospholipids, as well as liver phospholipids, in C20:5(n-3), C22:5(n-3) and C22:6(n-3). In plasma triacylglycerols, the weight percentages of C18:2(n-6) and C18:3(n-6) were lower in (n-3)-depleted mice than in control animals.

Rapid lipid enrichment in omega3 fatty acids: cause-to-effect relationships.

The bolus intravenous administration of a novel medium-chain triglyceride:fish oil emulsion to second generation rats depleted in long-chain polyunsaturated omega3 fatty acids was recently found to enrich within 60 min the content of both plasma and liver lipids in such omega3 fatty acids, this coinciding with correction of the perturbation in liver triglyceride fatty acid content and profile otherwise prevailing in these rats. The present report draws attention to cause-to-effect relationships between changes in liver phospholipid and triglyceride fatty acid content and/or pattern operative under these experimental conditions.

Rapid lipid enrichment in omega3 fatty acids: liver data.

The bolus intravenous injection of a novel medium-chain triglyceride:fish oil emulsion to normal subjects was recently reported to enrich within 60 min the phospholipid content of leucocytes and platelets in long-chain polyunsaturated omega3 fatty acids. The present study, conducted in second generation omega3-depleted rats, aims at investigating whether such a procedure may also increase within 60 min the phospholipid content of omega3 fatty acids in cells located outwards of the bloodstream, in this case liver cells, and whether this coincides with correction of the perturbation in the liver triglyceride fatty acid content and profile otherwise prevailing in these rats. The results indicate that such is indeed the case and further suggest a cause-to-effect relationship between the two events.

Rapid lipid enrichment in omega3 fatty acids: plasma data.

The bolus intravenous injection of a novel medium-chain triglyceride:fish oil emulsion to normal subjects was recently reported to enrich within 60 min the phospholipid content of leucocytes and platelets in long-chain polyunsaturated omega3 fatty acids. The present study, conducted in second generation omega3-depleted rats, aimed at investigating whether such a procedure may also increase within 60 min the phospholipid content of omega3 fatty acids in cells located outwards the bloodstream, in this case liver cells, and whether this coincides with correction of the perturbation in the liver triglyceride fatty acid content and profile otherwise prevailing in these rats. This first report deals mainly with the fatty acid pattern of plasma lipids in male omega3-depleted rats that were non-injected or injected with either the omega3-rich emulsion or a control medium-chain triglyceride:olive oil emulsion.

Preferential enrichment of liver phospholipids in docosahexaenoate relative to eicosapentaenoate in omega-3-depleted rats injected with a medium-chain triglyceride: fish oil emulsion.

The bolus intravenous injection of a novel medium-chain triglyceride:fish oil (FO) emulsion was recently proposed as a tool to provoke a rapid enrichment of cell phospholipids in long-chain polyunsaturated omega-3 fatty acids. In the present study, the enrichment of liver phospholipids and triglycerides in C20:5omega-3, C22:5omega-3 and C22:6omega-3 was assessed 60min after the intravenous administration of FO (1.0ml) to second-generation omega-3-depleted rats.
