Eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids are v-3 polyunsaturated fatty acids (PUFA), found primarily in marine lipids, that display several wellness advantages, which include the improvement of insulin sensitivity with beneficial effects against obesity plus the prevention of cardiovascular ailments [1?]. The American Heart Association recommends eating fish rich in v-3 fatty acids. In spite of several studies suggesting protective actions of EPA and DHA, the cellular and molecular rational for their intake remains of considerable interest. It can be assumed that these useful effects are linked to the capacity of both acids to inhibit the production of v-6 PUFA-derived prostaglandins and leukotrienes [5]. Additionally, current research have shown that a series of novel v-3 PUFA-derived compounds may very well be accountable for eliciting their effective effects [6?]. Resolvins and protectins happen to be shown one example is to display potent anti-inflammatory and immunoregulatory actions [9, 10]. Amongst bioactive lipid mediators, prostaglandins (PG) exert a plethora of biological activities. PGs from the 2-series are formed by cyclooxygenase (COX)-1 and COX-2 from RPC-1063 custom synthesis arachidonic acid (AA). COX converts AA (released from membrane phospholipids by means of the activity of numerous phospholipases, mostly phospho-lipases A2) towards the unstable cyclic endoperoxide intermediates PGG2/H2 [11]. PGH2 is subsequently metabolized to quite a few prostanoids, PGD2, PGE2, PGF2a, PGI2 and thromboxane A2 (TXA2) by means of the action of synthases (prostaglandin D synthase [PGDS], PGES, PGFS, PGIS and TXAS) [12,13]. In vitro, PGD2 spontaneously dehydrates to PGJ2 [14] which can be converted to 15deoxy-d12,14-PGJ2 (15d-PGJ2) inside the absence of albumin [15]. 15dPGJ2 has been detected in vivo [15,16] and has been shown to exhibit in vitro and in vivo anti-inflammatory and anti-proliferative effects [15,17]. The anti-inflammatory cyclopentenone PGs exert their effects, in portion, by binding and activating the peroxisome proliferator-activated receptor-gamma (PPAR-c) [18,19]. EPA can also be enzymatically converted by cyclooxygenase into PGH3 which in turn is converted towards the 3-series PGs, e.g., PGD3, PGE3, PGF3a and PGI3 [20?2]. The eicosanoids derived from EPA have much less inflammatory activities compared with these developed from AA [23?5]. A further mechanism by which v-3 PUFA could exert helpful effects is by modulating the secretion of adipocytokines [26, 27]. Adiponectin is amongst the most abundant plasma protein adipocytokines that shows anti-inflammatory, anti-atherogenic and insulin-sensitizing properties [28, 29]. The prospective mechanism by which v-3 PUFA modulate adiponectin secretion is notEPA-Derived Prostaglandin and Adiponectinfully understood, but may possibly partially involve PPAR-c [30-33] which has been shown to play a crucial role in the transcriptional activation of the adiponectin gene [34]. A current study showed the formation of J-series PGs from EPA [35]. The pathway by which 15d-PGJ3 could possibly be generated is shown in Fig. 1.
