Resolvin E2
Based on 1 Customer Validation
Resolvin E2 ((-)-Resolvin E2) is an endogenous lipid mediator produced from eicosapentaenoic acid (EPA) under the catalysis of 5-lipoxygenase (5-LOX), and its production increases in hypoxic environments. Resolvin E2 antagonizes BLT1, partially activates ChemR23, and promotes ubiquitin-proteasome-mediated degradation of COX-2. Resolvin E2 reduces the production of prostaglandin E2, blocks polymorphonuclear leukocyte infiltration, and promotes the resolution of airway inflammation. Resolvin E2 ameliorates lipopolysaccharide (LPS) (HY-D1056)-induced depressive-like behaviors. Resolvin E2 can be used in research related to depression, murine peritonitis, neonatal asthma, and other conditions.

Resolvin E2 (10 nM; 2-16 h) suppresses COX-2 protein expression in a time-dependent manner (significantly at 4-16 h) without altering COX-1 levels in human macrophage-like U937 cells[3].
Resolvin E2 (10 nM; 4-16 h) significantly reduces PGE2 production in human macrophage-like U937 cells[3].
Resolvin E2 (10 nM; 8 h) promotes COX-2 protein degradation via the ubiquitin-proteasome system in human macrophage-like U937 cells[3].

Cell Line:human macrophage-like U937 cells (differentiated with phorbol 12-myristate 13-acetate)
-
Concentration:10 nM
-
Incubation Time:2 h, 4 h, 8 h, 16 h
-
Result:Did not alter COX-1 protein levels at any time point tested.
Suppressed COX-2 protein expression in a time-dependent manner, with statistically significant suppression observed at 4 h, 8 h, and 16 h compared to the 0 h control.

-
Concentration:10 nM
-
Incubation Time:2 h, 4 h, 8 h, 16 h
-
Result:Did not suppress COX-2 mRNA expression at any time point tested, with no statistically significant differences compared to the 0 h control.
-
Cell Line:human macrophage-like U937 cells (differentiated with phorbol 12-myristate 13-acetate)
-
Concentration:10 nM (Resolvin E2); 0.3 μM (MG132 pretreatment)
-
Incubation Time:8 h (Resolvin E2); 30 min (MG132 pretreatment)
-
Result:Suppressed COX-2 protein expression when administered alone.
Had its COX-2 protein expression suppression abrogated by pretreatment with 0.3 μM MG132, which restored COX-2 protein levels to a similar level as the untreated control.
Resolvin E2 (1-100 ng; intravenous injection, intraperitoneal injection; single administration) potently reduces human neutrophils (PMN) infiltration in zymosan-induced murine peritonitis[2].
Resolvin E2 (300 ng/mouse; intranasal administration; once daily for 3 consecutive days) alleviates neonatal asthma in high-risk pups by reducing airway eosinophilia, pulmonary tissue infiltration, and allergenic cytokine levels[4].
