Eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids are v-3 polyunsaturated fatty acids (PUFA), found mainly in marine lipids, that show several overall health benefits, such as the improvement of insulin sensitivity with helpful effects against obesity and the prevention of cardiovascular illnesses [1?]. The American Heart Association recommends eating fish rich in v-3 fatty acids. Regardless of several research suggesting protective actions of EPA and DHA, the cellular and molecular rational for their intake remains of considerable interest. It is actually assumed that these advantageous effects are linked towards the capability of each 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 could possibly be responsible for eliciting their advantageous effects [6?]. Resolvins and protectins have already been shown one example is to show ITI007 cost potent anti-inflammatory and immunoregulatory actions [9, 10]. Among bioactive lipid mediators, prostaglandins (PG) exert a plethora of biological activities. PGs of the 2-series are formed by cyclooxygenase (COX)-1 and COX-2 from arachidonic acid (AA). COX converts AA (released from membrane phospholipids through the activity of several phospholipases, mainly phospho-lipases A2) for the unstable cyclic endoperoxide intermediates PGG2/H2 [11]. PGH2 is subsequently metabolized to several prostanoids, PGD2, PGE2, PGF2a, PGI2 and thromboxane A2 (TXA2) through the action of synthases (prostaglandin D synthase [PGDS], PGES, PGFS, PGIS and TXAS) [12,13]. In vitro, PGD2 spontaneously dehydrates to PGJ2 [14] that is converted to 15deoxy-d12,14-PGJ2 (15d-PGJ2) in 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 part, by binding and activating the peroxisome proliferator-activated receptor-gamma (PPAR-c) [18,19]. EPA may also be enzymatically converted by cyclooxygenase into PGH3 which in turn is converted to the 3-series PGs, e.g., PGD3, PGE3, PGF3a and PGI3 [20?2]. The eicosanoids derived from EPA have less inflammatory activities compared with those made from AA [23?5]. Another mechanism by which v-3 PUFA may well exert useful effects is by modulating the secretion of adipocytokines [26, 27]. Adiponectin is one of the most abundant plasma protein adipocytokines that shows anti-inflammatory, anti-atherogenic and insulin-sensitizing properties [28, 29]. The potential mechanism by which v-3 PUFA modulate adiponectin secretion is notEPA-Derived Prostaglandin and Adiponectinfully understood, but could partially involve PPAR-c [30-33] which has been shown to play an essential role within the transcriptional activation on the adiponectin gene [34]. A recent study showed the formation of J-series PGs from EPA [35]. The pathway by which 15d-PGJ3 might be generated is shown in Fig. 1. PGD3 will be initially dehydrated to 15d-PGD3 a.
