Expression of oleate 12-hydroxylase genes in Arabidopsis results in the accumulation of hydroxy fatty acids in seed triacylglycerol (TAG). The pathways by which these unusual fatty acids become incorporated into TAG are not well understood. We expressed a fatty acid hydroxylase cDNA in Arabidopsis mutant lines to assess the role of three enzymes implicated in TAG assembly in this species. Plants deficient in the expression of phospholipid:diacylglycerol acyltransferase-1 or -2 accumulated hydroxy fatty acids and showed no differences to equivalent transformed wild-type plants. Plants lacking diacylglylcerol acyltransferase activity were also able to accumulate hydroxy fatty acids in seed neutral lipids. Triacylglycerol species containing one and two hydroxy fatty acids were abundant, and small amounts of trihydroxy-TAG were detected. These results indicate that individually, the three enzymes do not play a major role in the incorporation of hydroxy fatty acids into TAG.

β-hydroxy fatty acids are a major component of lipid A moiety of lipopolysaccaride. We aimed to investigate the role of freeβ-hydroxy fatty acids on inflammation, as well as to evaluate their effects on cytokine release from human blood cells, and whether they exist in plasma of patients with chronic inflammatory diseases with/without insulin resistance. Peripheral venous blood was incubated withβ-hydroxy lauric andβ-hydroxy myristic acids (each 100 ng, 1μg, 10μg/mL) up to 24 hours. Cytokines were measured from culture media and plasma. Free fatty acids and biochemical parameters were also measured from patients' plasma. Onlyβ-hydroxy lauric acid significantly stimulated interleukin-6 production at 10μg/mL compared to control (533.9±218.1versus438.3±219.6pg/mL,P<.05). However, freeβ-hydroxy lauric and myristic acids were not found in patients' plasma. Therefore, freeβ-hydroxy lauric and myristic acids do not seem to have a role on sterile inflammation in chronic inflammatory diseases associated with insulin resistance.
