    ..The changes were not reflected in the fatty acid composition of liver microsomal phospholipids when expressed as micrograms fatty acid/g of liver. ..

    ..It appears that neither blood insulin levels nor insulin resistance is a factor affecting the delta9, delta6, and delta5 desaturase changes in mRNA and activity found with the sucrose-rich diet. ..
  3. Ves Losada A, Brenner R. Fatty acid delta 5 desaturation in rat liver cell nuclei. Mol Cell Biochem. 1995;142:163-70 pubmed
    ..This step would be essential in nuclear desaturation since when ATP and/or CoA (necessary for the acylation reaction) are omitted from the incubation mixture, the desaturation reaction does not take place. ..
  4. Mills D, Huang Y, Narce M, Poisson J. Psychosocial stress, catecholamines, and essential fatty acid metabolism in rats. Proc Soc Exp Biol Med. 1994;205:56-61 pubmed
    ..They also suggest that epinephrine is capable of altering the in vivo metabolism of essential fatty acids in the rat. ..
  5. Irazu C, Gonzalez Rodríguez S, Brenner R. Delta 5 desaturase activity in rat kidney microsomes. Mol Cell Biochem. 1993;129:31-7 pubmed
    ..Contrary to a report but in accordance to others, the present results suggest that rat kidneys can synthesize arachidonic acid at least to satisfy partially their needs for eicosanoid production. ..
  6. Cho H, Nakamura M, Clarke S. Cloning, expression, and fatty acid regulation of the human delta-5 desaturase. J Biol Chem. 1999;274:37335-9 pubmed
    ..Finally, a BLAST and Genemap search of the human genome revealed that the Delta-5 and Delta-6 desaturase genes reside in reverse orientation on chromosome 11 and that they are separated by <11,000 base pairs. ..

    ..Our results support the hypothesis on hormonal regulation of PUFA metabolism, which should be taken into account for specific nutritional recommendations. ..

    ..Our data for the first time indicates that maternal micronutrients differentially alter the activity and expression of fatty acid desaturases in the liver. ..

    ..In particular, arachidonic acid content in old rats was slightly higher than in young rats whereas contents in linoleic and docosahexaenoic acids varied little throughout the life span.(ABSTRACT TRUNCATED AT 250 WORDS) ..

    ..Thus, subcutaneous implantation of a melatonin-releasing pellet thus resulted in improved lipid metabolism in diabetic rats, probably through restored insulin resistance. ..

    ..The 20:4/18:2 ratio was maintained. Fenofibrate increased palmitic acid, but decreased stearic acid percentage in liver lipids. ..

    ..These findings support a significant role for reverse Delta5-desaturase as a natural antisense regulator of Delta5-desaturase. ..
