Abstract
Dugotrajni nakupljeni umor utječe na tjelesno i mentalno zdravlje ljudi, istodobno uzrokujući razne bolesti, uključujući sindrom kroničnog umora (CFS). Gotovo 40% cjelokupne populacije pati od značajnog stepena umora. Istraživanja ukazuju na vezu između proupalnog statusa i oksidacijskog stresa s pojavom kroničnog umora, dok sve veći broj studija ukazuje na terapijski potencijal protuupalnih i antioksidativnih sastojaka hrane. Cilj ovog rada je procjena utjecaja odabranih flavonoida i metabolita (apigenin, apigenin-7-O-glukozid, luteolin, luteolin-7-O-glukozid, apigenin-7-O-glukuronid, luteolin-7-O-glukuronid) te omega-3 masnih kiselina (dokosaheksaenska kiselina i eikosapentaenska kiselina) na proizvodnju upalnih medijatora (PLA2, COX-1, COX-2, mPGES-1, mPGES-2, cPGES, TXAS) na modelu rane upale, kao i ispitvanje ekspresije mRNA enzima cPLA2α, COX-1/2, mPGES-1/2, cPGES i TXAS uključenih u njihovu proizvodnju uz RT-qPCR. Smjese flavonoida s omega-3 masnim kiselinama, ovisno o primijenjenim koncentracijama i kombinacijama, inhibiraju ili potenciraju stvaranje PGE2 i TXA2 (kvantificiranih ELISA testom) u monocitima U937 stimuliranim lipopolisaharidom (LPS). Iste smjese, osim onih s luteolinom i luteolin-7-O-glukuronidom, povećavaju ekspresiju TXAS mRNA, ali bez izravne povezanosti s količinom proizvedenog TXA2. Najprominentniji protuupalni potencijal pokazuje kombinacija masnih kiselina s luteolinom, odnosno njegovim metabolitom, što ukazuje na racionalnu osnovu za njihovo uključivanje u daljnje faze istraživanja i testiranje terapijskog učinka u ublažavanju simptoma umora i CFS-a.
Abstract (english)
Prolonged accumulated fatigue threatens people’s physical and mental health, while causing various illnesses, including chronic fatigue syndrome (CFS). Almost 40% of the total population suffers from pathological fatigue. A link between pro-inflammatory status and oxidative stress with the onset of chronic fatigue, and diet significance are indicated. The aim of this study was to evaluate the influence of selected flavonoids and metabolites (apigenin, apigenin-7-O-glucoside, luteolin, luteolin-7-O-glucoside, apigenin-7-O-glucuronide, luteolin-7-O-glucuronide), and omega-3 fatty acids on the inflammatory mediators (PLA2, COX-1, COX-2, mPGES-1, mPGES-2, cPGES, TXAS) production in an early inflammation model and to examine the expression of corresponding mRNA enzymes cPLA2α, COX-1/2, mPGES-1/2, cPGES i TXAS (RT-qPCR). Mixtures of flavonoids with omega-3 fatty acids, depending on the applied concentrations and combinations, inhibit or potentiate the production of PGE2 and TXA2 (quantified by ELISA test) in LPS-stimulated U937 monocytes. The same mixtures, excluding the ones with luteolin and luteolin-7-O-glucuronide, increase the expression of TXAS mRNA without a direct relationship to the amount of TXA2 produced. The most prominent anti-inflammatory potential is shown by the combinations of fatty acids with luteolin and its metabolite, indicating a rational basis for their inclusion in further research and for testing their therapeutic effect in relieving symptoms of fatigue and CFS.
