Untargeted metabolomics uncovers metabolic dysregulation and tissue sensitivity in ACE2 knockout mice.[Pubmed:38496880]

Heliyon. 2024 Mar 8;10(6):e27472.

Angiotensin-converting enzyme 2 (ACE2) polymorphisms are associated with increased risk of type 2 diabetes mellitus (T2DM), obesity and dyslipidemia, which have been determined in various populations. Consistently, ACE2 knockout (ACE2 KO) mice display damaged energy metabolism in multiple tissues, especially the key metabolic tissues such as liver, skeletal muscle and epididymal white adipose tissue (eWAT) and show even more severe phenotype under high-fat diet (HFD) induced metabolic stress. However, the effects of ACE2 on global metabolomics profiling and the tissue sensitivity remain unclear. To understand how tissues independently and collectively respond to ACE2, we performed untargeted metabolomics in serum in ACE2 KO and control wild type (WT) mice both on normal diet (ND) and HFD, and in three key metabolic tissues (liver, skeletal muscle and eWAT) after HFD treatment. The results showed significant alterations in metabolic profiling in ACE2 KO mice. We identified 275 and 168 serum metabolites differing significantly between WT and ACE2 KO mice fed on ND and HFD, respectively. And the altered metabolites in the ACE2 KO group varied from 90 to 196 in liver, muscle and eWAT. The alterations in ND and HFD serum were most similar. Compared with WT mice, ACE2 KO mice showed an increase in N-phenylacetylglutamine (PAGln), Methyl indole-3-acetate, 5-hydroxytryptophol, cholic acid, deoxycholic acid and 12(S)-HETE, while LPC (19:0) and LPE (16:1) decreased. Moreover, LPC (20:0), LPC (20:1) and PC (14:0e/6:0) were reduced in both ND and HFD serum, paralleling the decreases identified in HFD skeletal muscle. Interestingly, DL-tryptophan, indole and Gly-Phe decreased in both ND and HFD serum but were elevated in HFD liver of ACE2 KO mice. A low level of l-ergothioneine was observed among liver, muscle, and epididymal fat tissue of ACE2 KO mice. Pathway analysis demonstrated that different tissues exhibited different dysregulated metabolic pathways. In conclusion, these results revealed that ACE2 deficiency leads to an overall state of metabolic distress, which may provide a new insight into the underlying pathogenesis in metabolic disorders in both ACE2 KO mice and in patients with certain genetic variant of ACE2 gene.

The Aqueous Extract of Brassica oleracea L. Exerts Phytotoxicity by Modulating H(2)O(2) and O(2)(-) Levels, Antioxidant Enzyme Activity and Phytohormone Levels.[Pubmed:37687333]

Plants (Basel). 2023 Aug 28;12(17):3086.

Allelopathic interactions between plants serve as powerful tools for weed control. Despite the increasing understanding of the allelopathic mechanisms between different plant species, the inhibitory effects of B. oleracea on weed growth remain poorly understood. In this study, we conducted experiments to demonstrate that B. oleracea extract can suppress the germination of Panicum miliaceum L.varruderale Kit. seeds as well as of the roots, shoots and hypocotyl elongation of P. miliaceum seedlings. Furthermore, we observed that B. oleracea extract reduced the levels of hydrogen peroxide and superoxide anion in the roots while increasing the activities of catalase and ascorbate peroxidase. In the shoots, B. oleracea extract enhanced the activities of superoxide dismutase and peroxidase. Moreover, the use of the extract led to an increase in the content of phytohormones (indole-3-acetic acid, indole-3-acetaldehyde, Methyl indole-3-acetate, N6-isoPentenyladenosine, dihydrozeatin-7-glucoside, abscisic acid and abscisic acid glucose ester) in P. miliaceum seedlings. Interestingly, the aqueous extract contained auxins and their analogs, which inhibited the germination and growth of P. miliaceum. This may contribute to the mechanism of the B. oleracea-extract-induced suppression of P. miliaceum growth.

Analytical Strategies for LC-MS-Based Untargeted and Targeted Metabolomics Approaches Reveal the Entomological Origins of Honey.[Pubmed:35023735]

J Agric Food Chem. 2022 Feb 2;70(4):1358-1366.

A comprehensive liquid chromatography-mass spectrometry (LC-MS)-based metabolomics approach was developed to discriminate honey harvested from Apis mellifera ligustica Spinola (A. mellifera) and Apis cerana cerana Fabricius (A. cerana). Based on an untargeted strategy, ultrahigh-performance liquid chromatography electrospray ionization quadrupole orbitrap high-resolution mass spectrometry (UPLC Q-Orbitrap) was combined with chemometrics techniques to screen and identify tentative markers from A. mellifera and A. cerana honey. In targeted metabolomics analysis, a sensitive method of solid-phase extraction followed by ultrahigh-performance liquid chromatography coupled with triple quadrupole tandem mass spectrometry (UPLC-MS/MS) was established for quantifying three markers, and the results showed that 3-amino-2-naphthoic acid and Methyl indole-3-acetate could be considered markers of A. cerana honey, as they were present in higher amounts in A. cerana honey than in A. mellifera honey, whereas kynurenic acid was determined to be a marker of A. mellifera honey. This work highlights critical information for the authentication of A. cerana and A. mellifera honey.

MicroRNA and regulation of auxin and cytokinin signalling during post-mowing regeneration of winter wheat (Triticum aestivum L.).[Pubmed:32866790]

Plant Physiol Biochem. 2020 Oct;155:769-779.

Winter wheat not only provides adequate fresh forage grass in winter, but also ensures ample grain production in summer. The mechanisms underlying the regeneration of winter wheat after mowing or grazing are not well understood. In this study, the miRNA expression profile of winter wheat was determined using RNA sequencing and the endogenous auxin and cis-zeatin concentrations, as well as the expression of related miRNA-targeted genes, were measured. During the post-mowing regeneration of winter wheat, the concentrations of endogenous indole-3-acetic acid (IAA), Methyl indole-3-acetate (ME-IAA), and indole-3-carboxaldehyde (ICA) decreased, while those of cis-zeatin (cZ) increased. Moreover, 15 novel miRNAs and three known miRNAs were found to be involved in the synthesis and signalling transduction of auxins and cytokinins (CKs). Among these miRNAs, miR1153-y, miR5059-x, miR2916-x, novel-miR1532-3p, novel-miR1060-3p, and novel-miR0890-3p, were found to be negatively correlated with the expression of their target genes including auxin response GH3.7, auxin response factor (ARF), type-A two-component response regulator (A-ARR), aldehyde dehydrogenase (ALDH), and O-glucosyltransferase (CISZOG). Furthermore, miR1153-y was identified as mediating the cleavage of GH3.7 by RACE assay. In turn, these genes inhibited the biosynthesis and signalling of IAA and activated CK signal transduction, resulting in the rapid regeneration of mowed winter wheat. This study revealed that some miRNAs exert a positive regulatory effect on the post-mowing regeneration of winter wheat by controlling the synthesis and signal transduction of IAA and CK, and our founding will aid developments in biotechnology aimed at improving the post-mowing regeneration ability of winter wheat.

Urinary intermediates of tryptophan as indicators of the gut microbial metabolism.[Pubmed:28916042]

Anal Chim Acta. 2017 Sep 22;987:72-80.

While over 10% of the human metabolome is directly associated with the gut microbial metabolism, specific metabolites are largely uncharacterized. Therefore, methods for the identification and quantification of microbiota-associated metabolites in biological fluids such as urine or plasma are necessary in order to elucidate the molecular basis of host-microbiota interaction. In this study, we focused on the tryptophan metabolism, employing quantitative assays by ultra-high performance liquid chromatography (UHPLC) and tandem mass spectrometry, specifically selected reaction monitoring (SRM). Metabolite standards were utilized to generate SRM library for 16 intermediates of the tryptophan metabolism which were human endogenous as well as microbiota-associated based on the HMDB classification. Next, the SRM assays were utilized for screening in maternal urine samples and in dried urine specimens from neonates. The approach resulted in the discovery of microbiota-associated metabolites (Methyl indole-3-acetate and methyl indol-3-propionate) previously unreported in urine samples and additionally in quantification of 8 intermediates of the tryptophan metabolism. To the best of our knowledge, this study represents the first attempt to explore previously unreported microbial metabolites in urine by UHPLC-SRM and novel methodology for simultaneous determination of microbiota-modulated component of Trp metabolism.

Molecular cloning and biochemical characterization of indole-3-acetic acid methyltransferase from poplar.[Pubmed:17499822]

Phytochemistry. 2007 Jun;68(11):1537-44.

Indole-3-acetic acid (IAA) is the most active endogenous auxin and is involved in various physiological processes in higher plants. Concentrations of IAA in plant tissues are regulated at multiple levels including de novo biosynthesis, conjugation/deconjugation, and degradation. In this paper, we report molecular isolation and biochemical characterization of a gene PtIAMT1 from poplar encoding IAA methyltransferase (IAMT), which plays a role in regulating IAA homeostasis. PtIAMT1 was identified from the poplar genome based on sequence similarity to Arabidopsis IAMT. A full-length cDNA of PtIAMT1 was cloned from poplar roots via RT-PCR. Recombinant PtIAMT1 expressed in Escherichia coli was purified to electrophoretic homogeneity. Enzyme assays combined with GC-MS verified that PtIAMT1 catalyzes formation of Methyl indole-3-acetate using S-adenosyl-l-methionine (SAM) as a methyl donor and IAA as a methyl acceptor. PtIAMT1 had a temperature optimum at 25 degrees C and a pH optimum at pH 7.5. Its activity was promoted by K(+) but inhibited by Fe(2+), Cu(2+) and Zn(2+). Under steady-state conditions, PtIAMT1 exhibited apparent K(m) values of 23.1 microM and 30.4 microM for IAA and SAM, respectively. Gene expression analysis showed that PtIAMT1 had the highest level of expression in stems, a moderate level of expression in young leaves, and a low level of expression in roots. Presence of PtIAMT1 transcripts in several organs suggests that PtIAMT1 is involved in development of multiple organs in poplar.

Monoamine oxidase A-inhibiting components of urinary tribulin: purification and identification.[Pubmed:8527006]

J Neural Transm Park Dis Dement Sect. 1995;9(2-3):225-37.

The endogenous monoamine oxidase (MAO) inhibitory activity, termed tribulin, contains several components. We have previously identified one of them, isatin, which is a selective inhibitor of MAO B. In the present study we have purified several further components of human urinary tribulin which act as selective inhibitors of MAO A. They have been identified by gas chromatography-mass spectrometry (GC-MS) as ethyl indole-3-acetate (and/or methyl indole-3-propionate), Methyl indole-3-acetate and ethyl 4-hydroxyphenylacetate. IC50 values for MAO A were found to be 44 microM (105 microM for methyl indole-3-propionate), 88 microM and 120 microM, respectively, whilst those for MAO B were each greater than 1 mM. The artificial formation of these esters was excluded by carrying the parent acids, from which they are presumably synthesized, through the purification procedure. As tribulin output is increased during stress or anxiety, these results point to a possible role for tryptamine and tyramine pathways in such disorders.
