Wei, Quanzeng;Liu, Gaixin;Zhang, Chengli;Sun, Juntao;Zhang, Yongqing research published 《 Identification of characteristic volatile compounds and prediction of fermentation degree of pomelo wine using partial least squares regression》, the research content is summarized as follows. The aim of this study was to evaluate the characteristic volatile organic compounds (VOCs) profile of pomelo wine and determine an index for predicting fermentation degree of pomelo wine. Fermentation conditions of pomelo fruit were: initial sugar content, 20 °Brix; pH 4.0; yeast inoculum size, 2 g of inoculum in 10000 g of fermentation medium; fermentation temperature, 28 °C; total fermentation time, 285 h. Changes in VOCs content in pomelo wine fermented for different periods were analyzed by gas chromatog.-mass spectrometry. In total, 105 VOCs were identified in pomelo wine throughout the fermentation process, which included 31 alkenes, 19 esters, 20 alcs., 11 aldehydes or ketones, 9 aromatics, 6 alkanes, 5 acids, and 4 other volatile compounds Differences in VOCs contents in pomelo wine at different fermentation stages were analyzed by principal component anal., cluster anal., and partial least squares regression (PLS). PLS models revealed that the ratio of α-phellandrene/geraniol in pomelo wine could be as the potential index for determining the fermentation degree of pomelo wine. This study provides evidence for improving the quality of pomelo wine for industrial production

In the present study, the antimicrobial effects against L. monocytogenes of the chitosan (CS) films incorporated with apricot (Prunus armeniaca) kernel essential oil (AKEO) at 0.5% and 1.0% were demonstrated in solid medium, micro-atm., liquid media and spiced beef. In the refrigerated storage for 24 days at 4°C, compared with the control sample, the levels of peroxide value (PV) and thiobarbituric acid (TBA) of the spiced beef packed by CS films incorporated AKEO at 0.5% and 1.0% were decreased to 4.8 and 3.6 meq peroxide/kg, and 0.5 and 0.4 mg MDA/kg (p < 0.5 or p < 0.1), and the levels for pH and total carbonyls (TC) were decreased to 5.8 and 5.7, and 0.7 and 0.6 nmol/mg protein (p < 0.5 or p < 0.1) on the 24th day, resp. Furthermore, the sensory evaluation exhibited that the spiced beef packed by CS films incorporated AKEO at 1.0% had better sensory attributes including taste, color, texture and overall acceptance during the whole storage period. Consequently, CS films incorporated AKEO at 1.0% can be developed to be one packaging material for spiced beef.

The amount of geranylgeranyl diphosphate (GGPP) is vital for microbial production of geranylgeraniol (GGOH) in Saccharomyces cerevisiae. In this study, a GGPP synthase with stronger catalytic ability was used to increase the supply of GGPP, and an engineered strain producing 374.02 mg/L GGOH at the shake flask level was constructed. Then, by increasing the metabolic flux of the mevalonate (MVA) pathway and the supply of isopentenyl pyrophosphate (IPP), the titer was further increased to 772.98 mg/L at the shake flask level, and we achieved the highest GGOH titer to date of 5.07 g/L in a 5 L bioreactor. This is the first report on the utilization of isoprenol for increasing the amount of IPP and enhancing GGOH production in S. cerevisiae. In the future, these strategies and engineered strains can be used to enhance the production of other terpenoids in S. cerevisiae.

Wang, Lai;Zhu, Lijun;Zheng, Zuguo;Meng, Lingchang;Liu, Hanling;Wang, Keke;Chen, Jun;Li, Ping;Yang, Hua research published 《 Mevalonate pathway orchestrates insulin signaling via RAB14 geranylgeranylation-mediated phosphorylation of AKT to regulate hepatic glucose metabolism》, the research content is summarized as follows. Statin use accompanies with increased risk of new onset of type 2 diabetes, however, the underlying mechanisms remain not be fully understood and effective prevention strategies are still lacking. Herein, we find that both pharmacol. and genetic inhibition of GGTase II mimic the disruption of simvastatin on hepatic insulin signaling and glucose metabolism in vitro. AAV8-mediated knockdown of liver RABGGTA, the specific subunit of GGTase II, triggers systemic glucose metabolism disorders in vivo. By adopting a small-scale siRNA screening, we identify RAB14 as a regulator of hepatic insulin signaling and glucose metabolism Geranylgeranylation deficiency of RAB14 inhibits the phosphorylation of AKT (Ser473) and disrupts hepatic insulin signaling and glucose metabolism possibly via impeding mTORC2 complex assembly. Finally, geranylgeranyl pyrophosphate (GGPP) supplementation is sufficient to prevent simvastatin-caused disruption of hepatic insulin signaling and glucose metabolism in vitro. Geranylgeraniol (GGOH), a precursor of GGPP, is able to ameliorate simvastatin-induced systemic glucose metabolism disorders in vivo. In our data indicate that statins-targeted mevalonate pathway regulates hepatic insulin signaling and glucose metabolism via geranylgeranylation of RAB14. GGPP/GGOH supplementation might be an effective strategy for the prevention of the diabetic effects of statins.

Psoriatic arthritis (PsA) is a chronic inflammatory joint disease, and the diagnosis is quite difficult due to the unavailability of reliable clin. markers. This study aimed to investigate the fecal metabolites in PsA by comparison with rheumatoid arthritis (RA), and to identify potential diagnostic biomarkers for PsA. The metabolic profiles of the fecal samples from 27 PsA and 29 RA patients and also 36 healthy controls (HCs) were performed on ultrahigh- performance liquid chromatog. coupled with hybrid triple quadrupole time-offlight mass spectrometry (UHPLC-Q-TOF-MS). And differentially altered metabolites were screened and assessed using multivariate anal. for exploring the potential biomarkers of PsA. The results showed that 154 fecal metabolites were significantly altered in PsA patients when compared with HCs, and 45 metabolites were different when compared with RA patients. A total of 14 common differential metabolites could be defined as candidate biomarkers. Furthermore, a support vector machines (SVM) model was performed to distinguish PsA from RA patients and HCs, and 5 fecal metabolites, namely, α/β-turmerone, glycerol 1-hexadecanoate, dihydrosphingosine, pantothenic acid and glutamine, were determined as biomarkers for PsA. Through the metabolic pathways anal., we found that the abnormality of amino acid metabolism, bile acid metabolism and lipid metabolism might contribute to the occurrence and development of PsA. In summary, our research provided ideas for the early diagnosis and treatment of PsA by identifying fecal biomarkers and analyzing metabolic pathways.

Uno, Shinpei;Masuya, Takahiro;Shinzawa-Itoh, Kyoko;Lasham, Jonathan;Haapanen, Outi;Shiba, Tomoo;Inaoka, Daniel Ken;Sharma, Vivek;Murai, Masatoshi;Miyoshi, Hideto research published 《 Oversized ubiquinones as molecular probes for structural dynamics of the ubiquinone reaction site in mitochondrial respiratory complex I》, the research content is summarized as follows. NADH-quinone oxidoreductase (complex I) couples electron transfer from NADH to quinone with proton translocation across the membrane. Quinone reduction is a key step for energy transmission from the site of quinone reduction to the remotely located proton-pumping machinery of the enzyme. Although structural biol. studies have proposed the existence of a long and narrow quinone-access channel, the physiol. relevance of this channel remains debatable. We investigated here whether complex I in bovine heart submitochondrial particles (SMPs) can catalytically reduce a series of oversized ubiquinones (OS-UQs), which are highly unlikely to transit the narrow channel because their side chain includes a bulky “block” that is ∼13 Å across. We found that some OS-UQs function as efficient electron acceptors from complex I, accepting electrons with an efficiency comparable with ubiquinone-2. The catalytic reduction and proton translocation coupled with this reduction were completely inhibited by different quinone-site inhibitors, indicating that the reduction of OS-UQs takes place at the physiol. reaction site for ubiquinone. Notably, the proton-translocating efficiencies of OS-UQs significantly varied depending on their side-chain structures, suggesting that the reaction characteristics of OS-UQs affect the predicted structural changes of the quinone reaction site required for triggering proton translocation. These results are difficult to reconcile with the current channel model; rather, the access path for ubiquinone may be open to allow OS-UQs to access the reaction site. Nevertheless, contrary to the observations in SMPs, OSUQs were not catalytically reduced by isolated complex I reconstituted into liposomes. We discuss possible reasons for these contradictory results.

Upadhyay, Prabhat;Shukla, Rashmi;Tiwari, Kavindra Nath;Dubey, G. P.;Mishra, Sunil Kumar research published 《 Neuroprotective effect of Reinwardtia indica against scopolamine induced memory-impairment in rat by attenuating oxidative stress》, the research content is summarized as follows. Reinwardtia indica belongs to Linaceae family and used as a folk medicine in Asian countries. Traditionally, it has been used in the treatment of paralysis and anti-microbial in wound healing, etc. The current study was undertaken in order to investigate the antioxidant and memory protective effect of the alc. (99.90%) (AERI) and hydro-alc. (70:30) leaves extract (HAERI) of Reinwardtia indica, against scopolamine-induced memory impairment in animals and also tried to determine the possible mechanism of action. In addition, phytochem. profiling of alc. leaves extract was also conducted through gas chromatog.-mass spectrometry. Rats were pretreated with AERI, HAERI (dose 250 and 500 mg/kg) and Donepezil (standard drug) along with scopolamine (1 mg/kg) for a period of 14 days followed by different test like elevated plus maze, passive avoidance, and Morris water maze to assess learning and memory ability. Acetylcholine levels, acetylcholinesterase (AChE), antioxidant enzymes (SOD, CAT & GSH), histopathol. of the brain and biochem. test were also performed at the end of the treatment period. The scopolamine treatment resulted in learning and memory deficits which were partially and significantly ameliorated by the AERI at higher dose among other doses of extracts The AERI at higher dose also counteracted the scopolamine-induced decrease in acetylcholine levels, increase in AChE activity, and decrease in antioxidant enzymes activities. No significant changes observed in the biochem. estimation of all dose of extracts Histol. of brain tissue showed the marked cellular changes in only scopolamine treated group while the standard, AERI and HAERI treated group were showing less damage at hippocampus region of the brain. The phytochems. found after chem. profiling through GC-MS also supported the activity because of the presence of chems. already reported for the neuroprotective, memory-enhancing and antioxidant activity, etc. The results demonstrated that the ability of the AERI at higher dose among all doses of extracts has more potential to revert the scopolamine-induced learning and memory deficits in rats by attenuating the decreased level of acetylcholine and antioxidant enzymes.

Tabata, Yuki;Shidoji, Yoshihiro research published 《 Hepatic monoamine oxidase B is involved in endogenous geranylgeranoic acid synthesis in mammalian liver cells》, the research content is summarized as follows. Recently, we reported that in human hepatoma-derived HuH-7 cells, GGA is metabolically labeled from 13C-mevalonate. Several cell-free experiments have demonstrated that GGA is synthesized through geranylgeranial by oxygen-dependent oxidation of geranylgeraniol (GGOH), but the exact biochem. events giving rise to GGA in hepatoma cells remain unclear. Monoamine oxidase B (MOAB) has been suggested to be involved in GGOH oxidation Here, using two human hepatoma cell lines, we investigated whether MAOB contributes to GGA biosynthesis. Using either HuH-7 cell lysates or recombinant human MAOB, we found that: 1) the MAO inhibitor tranylcypromine dose-dependently downregulates endogenous GGA levels in HuH-7 cells; and 2) siRNA-mediated MAOB silencing reduces intracellular GGA levels in HuH-7 and Hep3B cells. Unexpectedly, however, CRISPR/Cas9-generated MAOB-KO human hepatoma Hep3B cells had GGA levels similar to those in MAOB-WT cells. A sensitivity of GGA levels to siRNA-mediated MAOB downregulation was recovered when the MAOB-KO cells were transfected with a MAOB-expression plasmid, suggesting that MAOB is the enzyme primarily responsible for GGOH oxidation and that some other latent metabolic pathways may maintain endogenous GGA levels in the MAOB-KO hepatoma cells. Along with the previous findings, these results provide critical insights into the biol. roles of human MAOB and provide evidence that hepatic MAOB is involved in endogenous GGA biosynthesis via GGOH oxidation

Tabata, Yuki;Omori, Masahide;Shidoji, Yoshihiro research published 《 Age-Dependent Decrease in Hepatic Geranylgeranoic Acid Content in C3H/HeN Mice and Its Oral Supplementation Prevents Spontaneous Hepatoma》, the research content is summarized as follows. Geranylgeranoic acid (GGA) has been developed as a preventive agent against second primary hepatoma. Recently, GGA was reported to induce cell death in human hepatoma cells via TLR4-mediated pyroptosis. We have reported that GGA is enzymically biosynthesized from mevalonic acid in human hepatoma-derived cells and that endogenous GGA is found in most organs of rats. In addition, we found that upregulation of endogenous GGA levels by zaragozic acid A (ZAA) induced cell death in human hepatoma-derived cells. Therefore, we investigated the age-related changes in hepatic GGA and the possibility of suppressing hepatocarcinogenesis by GGA supplementation using male C3H/HeN mice that spontaneously develop hepatoma. We measured endogenous GGA and mRNA of monoamine oxidase (BMAOB), a key enzyme of GGA biosynthesis, in the liver of male C3H/HeN mice aged 6-93 wk. We also tried suppressing spontaneous hepatocarcinogenesis by a single administration of GGA to C3H/HeN mice. Hepatic GGA content and Maob mRNA expression level age-dependently decreased in male C3H/HeN mice; some of which produced spontaneous hepatoma in 2 years. A single oral administration of GGA at 11 mo of age significantly prevented hepatoma in terms of the number and weight of tumors per mouse at 24 mo. Oral supplementation with GGA or geranylgeraniol significantly increased endogenous hepatic GGA contents dose-dependently; and ZAA dramatically upregulated hepatic GGA. In this study; we found an age-dependent decrease in hepatic endogenous GGA in male C3H/HeN mice and efficient prevention of spontaneous hepatoma by a single administration of GGA at 11 mo of age.
