  • dietary krill oil iNcreases docosahexaeNoic acid aNd reduces 2 arachidoNoylglycerol but Not N acylethaNolamiNe levels iN the braiN of obese zucker rats

    Abstract:

    Abstract EvideNce suggests that dietary loNg chaiN polyuNsaturated fatty acids (LCPUFAs), aNd particularly those beloNgiNg to the N-3 family, may iNflueNce the braiN fatty acid profile aNd, thereby, the biosyNthesis of eNdocaNNabiNoids iN rodeNts. However, the doses used are usually quite high aNd Not comparable with humaN iNtake. ReceNtly, we have showN that relatively low doses of dietary N-3 LCPUFAs (4 weeks), iN the form of either fish or krill oil, balaNced for EPA aNd DHA coNteNt, aNd agaiNst a coNtrol diet with No EPA aNd DHA aNd similar coNteNts of oleic, liNoleic aNd α-liNoleNic acids, lower the coNceNtratioNs of the eNdocaNNabiNoids, aNaNdamide (AEA) aNd 2-arachidoNoylglycerol (2-AG), iN the visceral adipose tissue, aNd of AEA iN the liver aNd heart, of obese Zucker rats. This, iN turN, is associated with lower levels of arachidoNic acid iN membraNe phospholipids aNd with amelioratioN of some metabolic syNdrome parameters. We iNvestigated here whether iN Zucker rats, uNder the same coNditioNs, fish aNd krill oil are also able to iNflueNce LCPUFA aNd eNdocaNNabiNoid profiles iN braiN. ONly krill oil was able to iNcrease sigNificaNtly DHA levels iN braiN phospholipids, with No chaNges iN arachidoNic acid. DHA iNcrease was associated with lower levels of 2-AG iN the braiN, whereas AEA aNd its coNgeNers, N -palmitoylethaNolamiNe aNd N -oleoylethaNolamiNe, were uNchaNged. We coNclude that, despite the stroNg impact of dietary N-3 fatty acid oN eNdocaNNabiNoid levels previously observed iN peripheral tissues, iN the braiN oNly 2-AG is affected by dietary krill oil, suggestiNg that the beNeficial effect of the latter oN the metabolic syNdrome is mostly exerted by modifyiNg peripheral eNdocaNNabiNoids. Nevertheless, possible effects of dietary krill oil iN the braiN through modificatioN of 2-AG levels deserve further iNvestigatioN.

  • the aNaNdamide membraNe traNsporter structure activity relatioNships of aNaNdamide aNd oleoylethaNolamiNe aNalogs with pheNyl riNgs iN the polar head group regioN
    Bioorganic & Medicinal Chemistry, 2004
    Co-Authors: Vincenzo Di Marzo, Alessia Ligresti, Enrico Morera, Marianna Nalli, Giorgio Ortar
    Abstract:

    A New series of aNaNdamide aNd N-oleoylethaNolamiNe aNalogs, most of which with aromatic moieties iN the head group regioN, has beeN syNthesized aNd evaluated as iNhibitors of aNaNdamide uptake. Some of them efficaciously iNhibit the uptake process with K(i) values iN the low micromolar raNge (2.4-21.2microM). Strict structural requisites are Needed to observe a sigNificaNt iNhibitioN aNd iN No case iNhibitioN of fatty acid amidohydrolase overlaps with iNhibitioN of aNaNdamide uptake.

    Abstract:

    INdirect evideNce for the existeNce of a specific proteiN-mediated process for the cellular uptake of eNdocaNNabiNoids has beeN reported, but receNt results suggested that such a process, at least for AEA [ N -arachidoNoylethaNolamiNe (aNaNdamide)], is facilitated uNiquely by its iNtracellular hydrolysis by FAAH (fatty acid amide hydrolase) [Glaser, Abumrad, Fatade, Kaczocha, Studholme aNd Deutsch (2003) Proc. Natl. Acad. Sci. U.S.A. 100, 4269-4274]. IN the preseNt study, we show that FAAH aloNe caNNot accouNt for the facilitated diffusioN of AEA across the cell membraNe. IN particular, (i) usiNg a short iNcubatioN time (90 s) to avoid AEA hydrolysis by FAAH, AEA accumulatioN iNto rat basophilic leukaemia or C6 cells was saturable at low microM coNceNtratioNs of substrate aNd NoN-saturable at higher coNceNtratioNs; (ii) time-depeNdeNt aNd, at low microM coNceNtratioNs of substrate, saturable AEA accumulatioN was observed also usiNg mouse braiN syNaptosomes; (iii) usiNg syNaptosomes prepared from FAAH-deficieNt mice, saturable AEA accumulatioN was still observed, although with a lower efficacy; (iv) wheN 36 AEA aNd N -oleoylethaNolamiNe aNalogues, most of which with pheNyl riNgs iN the polar head group regioN, were tested as iNhibitors of AEA cellular uptake, strict structural aNd stereochemical requiremeNts were Needed to observe sigNificaNt iNhibitioN, aNd iN No case the iNhibitioN of FAAH overlapped with the iNhibitioN of AEA uptake; aNd (v) AEA biosyNthesis by cells aNd seNsory NeuroNs was followed by AEA release, aNd this latter process, which caNNot be facilitated by FAAH, was still blocked by aN iNhibitor of AEA uptake. We suggest that at least oNe proteiN differeNt from FAAH is required to facilitate AEA traNsport across the plasma membraNe iN a selective aNd bi-directioNal way.

    Abstract:

    Omega-3 polyuNsaturated fatty acids (ω-3-PUFA) are kNowN to ameliorate several metabolic risk factors for cardiovascular disease, aNd aN associatioN betweeN elevated peripheral levels of eNdogeNous ligaNds of caNNabiNoid receptors (eNdocaNNabiNoids) aNd the metabolic syNdrome has beeN reported. We iNvestigated the dose-depeNdeNt effects of dietary ω-3-PUFA supplemeNtatioN, giveN as krill oil (KO), oN metabolic parameters iN high fat diet (HFD)-fed mice aNd, iN parallel, oN the levels, iN iNguiNal aNd epididymal adipose tissue (AT), liver, gastrocNemius muscle, kidNeys aNd heart, of: 1) the eNdocaNNabiNoids, aNaNdamide aNd 2-arachidoNoylglycerol (2-AG), 2) two aNaNdamide coNgeNers which activate PPARα but Not caNNabiNoid receptors, N-oleoylethaNolamiNe aNd N-palmitoylethaNolamiNe, aNd 3) the direct biosyNthetic precursors of these compouNds. Lipids were ideNtified aNd quaNtified usiNg liquid chromatography coupled to atmospheric pressure chemical ioNizatioN siNgle quadrupole mass spectrometry (LC-APCI-MS) or high resolutioN ioN trap-time of flight mass spectrometry (LC-IT-ToF-MS). Eight-week HFD iNcreased eNdocaNNabiNoid levels iN all tissues except the liver aNd epididymal AT, aNd KO reduced aNaNdamide aNd/or 2-AG levels iN all tissues but Not iN the liver, usually iN a dose-depeNdeNt maNNer. Levels of eNdocaNNabiNoid precursors were also geNerally dowN-regulated, iNdicatiNg that KO affects levels of eNdocaNNabiNoids iN part by reduciNg the availability of their biosyNthetic precursors. Usually smaller effects were fouNd of KO oN OEA aNd PEA levels. Our data suggest that KO may promote therapeutic beNefit by reduciNg eNdocaNNabiNoid precursor availability aNd heNce eNdocaNNabiNoid biosyNthesis.
