DESs, along with allene oxide synthases (AOSs), hydroperoxide lyases (HPLs), and epoxyalcohol synthases (EASs), are members of the CYP74 clan of unusual cytochromes P450 playing a key role in the lipoxygenase pathway. The present work focuses on the study of the structure-function relationships in Asparagus officinalis DES (AoDES, CYP74H2) via site-directed mutagenesis at some catalytically essential sites. Single mutant forms L106F and L282G retained the DES activity. However, the L106F mutant possessed significant alteration of stereochemical specificity of divinyl ether synthesis compared with WT AoDES. For example, while WT AoDES specifically converted linoleic acid 13(S)-hydroperoxide into (11Z)-etheroleic acid, its yield was significantly reduced by the L106F mutation, whereas etheroleic and (all-E)-etheroleic acids were the major ones. In contrast, the L282G mutation did not significantly affect the (11Z)-etheroleic acid formation. However, the L282G protein produced some additional products like those of HPL and EAS, along with divinyl ethers. The L106F/L282G double mutant protein lost DES activity. It converted α-linolenic 9- and 13-hydroperoxides into HPL chain cleavage products. At the same time, this mutant efficiently converted the linoleic acid 9-hydroperoxide into diol, 9,14-dihydroxy-10,12-octadecadienoic acid, presumably via the hydrolysis of the short-lived epoxydiene, 9,10-epoxy-11,13-octadecadienoic acid. Furthermore, the L106F/L282G/Q343P triple mutant showed AOS activity alongside DES. The appearance of EAS and HPL catalysis, as well as the biosynthesis of 9,14-epoxydiene via short-lived epoxydiene via site-directed mutagenesis in the catalytically relevant domains of DES, was demonstrated for the first time.</p>","PeriodicalId":8815,"journal":{"name":"Biochimica et biophysica acta.

However, much less is known for their roles in fish. The current study demonstrated that AdipoRon, a small-molecule activator of AdipoRs, modulated glucose and lipid metabolism in large yellow croaker. In hepatocytes of large yellow croaker, AdipoRon upregulated the mRNA expression of adipors and appl1, while increasing phosphorylation levels of AMPK and AKT. These changes indicate the activation of AdipoR-mediated signaling. Furthermore, AdipoRon promoted glucose uptake, increased intracellular glucose content, as well as upregulated genes involved in glycogen synthesis and glycolysis whereas downregulated gluconeogenesis-related genes. On the other hand, AdipoRon facilitated free fatty acid (FFA) absorption by increasing the expression of fatty acid transport genes (fat/cd36, fatp1, and fabp11). It also enhanced triglyceride (TG) synthesis, evidenced by increased triglyceride levels and upregulation of dgat2 and PPARγ, which is consistent with the effect of adiponectin (APN) in large yellow croaker. Additional evidence suggested that inhibition of PPARγ with GW9662 reduced the effects of AdipoRon on glucose uptake and lipid metabolism, indicating that PPARγ is a key mediator in these metabolic regulations. Overall, AdipoRon was found to modulate multiple metabolic processes in hepatocytes of large yellow croaker via PPARγ signaling pathway, and these findings suggested that AdipoRon might contribute to beneficial effects on metabolic homeostasis in teleosts.</p>","PeriodicalId":8815,"journal":{"name":"Biochimica et biophysica acta.

Moreover, the physiological functions and bioactivities of PUFA-derived oxylipins warrant further exploration. In this study, we found that appropriate dietary linoleic acid (LA)/n-3 PUFAs enhanced the growth of the clam Sinonovacula constricta and improved its survival under hydrogen peroxide (H₂O₂) stress. Targeted lipidomic showed that the high-LA diet increased accumulation of LA and LA-derived oxylipins. Interestingly, a similar pattern was observed for α-linolenic acid (ALA) and ALA-derived oxylipins, potentially contributing to the anti-inflammatory and antioxidant effects of this dietary pattern. However, dietary n-3 PUFAs provided greater protection against H₂O₂-induced damage. Dietary n-3 PUFAs significantly increased the levels of oxylipins derived from docosahexaenoic acid and eicosapentaenoic acid, particularly 14(S)-hydroxydocosahexaenoic acid (14(S)-HDHA) and 12-hydroxyeicosapentaenoic acid (12-HEPE). Furthermore, 14(S)-HDHA and 12-HEPE restored cell viability in hydrogen peroxide (H₂O₂)-treated RAW264.7 cells. Mechanistically, 12-HEPE inhibited nuclear factor kappa B (NF-κB) nuclear translocation while promoting nuclear translocation of nuclear factor erythroid 2-related factor 2 (Nrf2), thereby reducing inflammatory responses and enhancing antioxidant capacity. Additionally, 12-HEPE increased antioxidant activity and suppressed inflammatory gene expression in clam hemolymph cells. This study represents the first comprehensive evaluation of the oxylipin profile in bivalves, further emphasizing the importance of dietary n-3 PUFAs intake in shaping n-3 PUFA-derived oxylipins and consequently influencing inflammation and redox status.

Omega-3 PUFA, including docosahexaenoic acid (DHA), are precursors to a novel class of bioactive metabolites called specialized pro-resolving mediators (SPMs), which have been suggested to have a dual purpose in mitigating neuroinflammation while simultaneously supporting cognitive outcomes, implicating a role in offspring neurodevelopment. DHA is evidenced for its role in early brain development, but the underlying mechanism it exerts its cognitive benefits remain unclear. Pregnant sows were fed a control diet (CON; <em>n</em> = 6) or a diet with DHA (<em>n</em> = 6, 75 mg DHA/kg BW/day) from gestation through lactation. At weaning, piglets (<em>n</em> = 2/sow) underwent resting state-functional magnetic resonance imaging (rs-fMRI) to assess brain functional activation. Subsequently, brain tissue from prefrontal cortex, cerebellum, and hippocampus were collected from piglets. Tissue DHA and eicosapentaenoic acid (EPA)-derived SPMs were quantified using LC-MS. Levels of SPMs were higher in the brains of piglets from DHA-fed sows, particularly in the prefrontal cortex and cerebellum, compared to control piglets. Additionally, a distinct association of several prefrontal SPMs with activation of the cerebellar functional network was marked in the piglet offspring. The findings highlight a potential for SPMs to function as mediators for neurodevelopmental programming, through contributing to inflammation resolution and neuronal connectivity. This work underscores the importance of maternal nutrition in shaping offspring brain health and lays the groundwork for targeted interventions leveraging the benefits of DHA and its bioactive metabolites.</div></div>","PeriodicalId":8815,"journal":{"name":"Biochimica et biophysica acta.

The underlying mechanisms of oroxylin A were further explored through Western blotting, immunohistochemistry, and immunofluorescence analysis. Oroxylin A mitigated hepatic steatosis and injury by reducing liver index, AST, ALT, TG, and TC levels, improving histology, and restoring lipid metabolism. Glucose and insulin tolerance tests demonstrated improved glucose homeostasis and insulin sensitivity. Moreover, oroxylin A suppressed inflammation, apoptosis, and fibrosis, while enhancing antioxidant defenses, and improving mitochondrial function. Mechanistically, oroxylin A activated the Keap1/Nrf2/GPX4/SLC7A11 axis, upregulating Nrf2 and HO-1. These effects were abolished in Nrf2^-/- mice.

Despite tantalizing evidence to the effect that lipids can move between organelles independently of standard modes of vesicular membrane trafficking through the secretory pathway, biochemical dissection of these non-vesicular pathways was initially fraught with experimental challenges. Many of the obstacles have now been overcome and, following initial breakthroughs, the last two decades have witnessed a renaissance in the field of lipid trafficking. Indeed, lipid trafficking and mobilization are now significant components of any discussion regarding secretory vesicle trafficking, organelle biogenesis, agonist-stimulated lipid signaling, and inter-compartmental communication pathways that involve every organelle in the eukaryotic cell. In accord with the theme of this special issue, we focus on the topic of soluble lipid transfer proteins that interface with the metabolism of phosphatidylinositol (PtdIns) and its phosphorylated derivatives – the phosphoinositides. Although phosphoinositides are quantitatively minor lipids in cells, these molecules represent the chemical codes for a major pathway of intracellular signaling in all eukaryotic cells. It is now clear that soluble PtdIns transfer proteins (PITPs) are physiologically critical regulators of specific pathways of phosphoinositide – particularly PtdIns-4-phosphate – signaling. The ‘where’ PITPs determine the biological outcomes of phosphoinositide signaling, and the ‘how’ by which PITPs do so, represent increasingly active areas of research in contemporary cell biology.
