The effect of recalcitrant hydrocarbons on the fatty acid profile from leaf, basal corm, and roots of Cyperus laxus plants cultivated in greenhouse phytoremediation systems of soils from aged oil spill-impacted sites containing from 16 to 340 g/Kg total hydrocarbons (THC) was assessed to investigate if this is a C18:3 species and if the hydrocarbon removal during the phytoremediation process ha...

BACKGROUND The effect of dietary fats on human health and disease are likely mediated by changes in gene expression. Several transcription factors have been shown to respond to fatty acids, including SREBP-1c, NF-kappaB, RXRs, LXRs, FXR, HNF4alpha, and PPARs. However, it is unclear to what extent these transcription factors play a role in gene regulation by dietary fatty acids in vivo. METHOD...

Drought affects yield of peanut, but its effect on oleic and linoleic acids that influence its oil quality of peanut genotypes with different levels of drought resistance has not been clearly investigated. Therefore, the aims of this research were to determine whether soil water levels could affect oil quality by changes in fatty acid compositions of peanut, and to investigate the changes i...

The utilization of 1-alkenes by Micrococcus cerificans was investigated with respect to characteristic fatty acid profiles resulting from growth at the expense of these substrates. Saturated fatty acids containing even numbers of carbon atoms were produced from 1-dodecene and 1-tetradecene. Unsaturated fatty acids related to the parent alkene were not detected. The fatty acid profile from 1-pen...

The interaction of free fatty acids with cell membranes and lipid bilayers was studied by monitoring the emission polarization changes of the fluorescent probes 1,6-diphenyl-1,3,5-hexatriene (DPH) and 8-anilino-1-naphthalene sulfonate (ANS). It was found that cis unsaturated fatty acids incorporated into plasma membranes reduced DPH and increased ANS polarization, while trans-unsaturated and sa...

Background: For understanding the roles of fatty acids on the induction of acrosome reaction which occurs under association of cholesterol efflux and PKA or PKC pathways in boar spermatozoa, metabolic fate of alone and combined radiolabeled 14C-oleic acid and 3H-linoleic acid incorporated in the sperm was compared, and behavior of cholesterol and effects of PKA and PKC inhibitors upon fatty aci...

Hepatitis C virus (HCV) replication is dependent on the formation of specialized membrane structures; however, the host factor requirements for the formation of these HCV complexes remain unclear. Herein, we demonstrate that inhibition of stearoyl-CoA desaturase 1 (SCD-1) halts the biosynthesis of unsaturated fatty acids, such as oleic acid, and negatively modulates HCV replication. Unsaturated...
