Influence de la teneur en acide linolénique du régime maternel sur la composition en acides gras polyinsaturés des fractions subcellulaires au cours du développement cérébral chez le rat

Abstract: In order to determine precisely the respective roles of linolenic acid and linoleic acid in the maternal diet on rat brain subcellular fractions during development, we used two diets with different percentages of linolenic acid (18:3 n-3). The animals were fed peanut oil (group A) or soybean oil (group B) during pregnancy and throughout lactation. Nature and amount of essential fatty acids had no incidence on saturated and monounsaturated fatty acid distributions in myelin, synaptosomal, mitochondrial and micr… Show more

“…In deed, cultures of fetal cells that had been obtained from cerebral hemispheres of mice on the 16th day of fetal life indicate that the simultaneous addition of 22:6 n-3 an 20:4 n-6 to the artificial culture medium is neces sary to obtain a fatty acid profile similar to that of living tissue at the same age [18]. Although it is not possible to exclude the hypothesis of a direct capture of 18:2 n-6 and 18:3 n-3 as precursors, such a phenomen should be of quantitatively minor impor tance for two reasons: first, in similar experi mental conditions, the analysis of cerebral lipids indicated only small amounts of these fatty acids [12,19], Second, serum phospho lipids are also poor in 18:3 n-3. but high in linoleic acid.…”
