Gu SY, Lu HW, Bai JW, Yang JW, Mao B, Yu L, Xu JF. The role of volatile organic compounds for assessing characteristics and severity of non-cystic fibrosis bronchiectasis: an observational study. Front Med (Lausanne) 2024; 11:1345165. [PMID: 38633315 PMCID: PMC11022847 DOI: 10.3389/fmed.2024.1345165] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Accepted: 03/18/2024] [Indexed: 04/19/2024] Open
Abstract
Background Hypoxic conditions and Pseudomonas aeruginosa (P. aeruginosa) infection are significant factors influencing the prognosis and treatment of patients with bronchiectasis. This study aimed to explore the potential for breath analysis to detect hypoxic conditions and P. aeruginosa infection in bronchiectasis patients by analyzing of volatile organic compounds (VOCs) in exhaled breath condensate (EBC). Methods EBC samples were collected from stable bronchiectasis patients and analyzed using solid phase microextraction-gas chromatography-mass spectrometry (SPME-GCMS). The association of VOCs with bronchiectasis patients' phenotypes including hypoxic conditions and P. aeruginosa isolation was analyzed, which may relate to the severity of bronchiectasis disease. Results Levels of 10-heptadecenoic acid, heptadecanoic acid, longifolene, and decanol in the hypoxia group were higher compared to the normoxia group. Additionally, the levels of 13-octadecenoic acid, octadecenoic acid, phenol, pentadecanoic acid, and myristic acid were increased in P. aeruginosa (+) group compared to the P. aeruginosa (-) group. Subgroup analysis based on the bronchiectasis severity index (BSI)reveled that the levels of 10-heptadecenoic acid, heptadecanoic acid, decanol, 13-octadecenoic acid, myristic acid, and pentadecanoic acid were higher in the severe group compared to the moderate group. Multivariate linear regression showed that 10-heptadecenoic acid and age were independent prognostic factors for bronchiectasis patients with hypoxia. Furthermore, octadecenoic acid, phenol and gender were identified as independent prognostic factors for bronchiectasis patients with P. aeruginosa isolation. Conclusion The study provides evidence that specific VOCs in EBC are correlated with the severity of bronchiectasis, and 10-heptadecenoic acid is shown to be a predictive marker for hypoxia condition in bronchiectasis patients.

Abstract
This study investigates a mechanistic link of bacterial biofilm-mediated host-pathogen interaction leading to immunological complications associated with breast implant illness (BII). Over 10 million women worldwide have breast implants. In recent years, women have described a constellation of immunological symptoms believed to be related to their breast implants. We report that periprosthetic breast tissue of participants with symptoms associated with BII had increased abundance of biofilm and biofilm-derived oxylipin 10-HOME compared with participants with implants who are without symptoms (non-BII) and participants without implants. S. epidermidis biofilm was observed to be higher in the BII group compared with the non-BII group and the normal tissue group. Oxylipin 10-HOME was found to be immunogenically capable of polarizing naive CD4+ T cells with a resulting Th1 subtype in vitro and in vivo. Consistently, an abundance of CD4+Th1 subtype was observed in the periprosthetic breast tissue and blood of people in the BII group. Mice injected with 10-HOME also had increased Th1 subtype in their blood, akin to patients with BII, and demonstrated fatigue-like symptoms. The identification of an oxylipin-mediated mechanism of immune activation induced by local bacterial biofilm provides insight into the possible pathogenesis of the implant-associated immune symptoms of BII.

Abstract
Hydroxy unsaturated fatty acids can be used as antimicrobial surfactants. 8,11-Linoleate diol synthase (8,11-LDS) catalyzes the conversion of unsaturated fatty acid to 8-hydroperoxy unsaturated fatty acid, and it is subsequently isomerized to 8,11-dihydroxy unsaturated fatty acid by the enzyme. The optimal reaction conditions of recombinant Escherichia coli expressing Penicillium chrysogenum 8,11-LDS for the production of 8,11-dihydroxy-9,12(Z,Z)-octadecadienoic acid (8,11-DiHODE), 8,11-dihydroxy-9,12,15(Z,Z,Z)-octadecatrienoic acid (8,11-DiHOTrE), 8-hydroxy-9(Z)-hexadecenoic acid (8-HHME), and 8-hydroxy-9(Z)-octadecenoic acid (8-HOME) were pH 7.0, 25°C, 10 g/L linoleic acid, and 20 g/L cells; pH 6.0, 25°C, 6 g/L α-linolenic acid, and 60 g/L cells; pH 7.0, 25°C, 8 g/L palmitoleic acid, and 25 g/L cells; and pH 8.5, 30°C, 6 g/L oleic acid, and 25 g/L cells, respectively. Under these optimized conditions, the recombinant cells produced 6.0 g/L 8,11-DiHODE for 60 min, with a conversion of 60% (w/w) and a productivity of 6.0 g/L/h; 4.3 g/L 8,11-DiHOTrE for 60 min, with a conversion of 72% (w/w) and a productivity of 4.3 g/L/h; 4.3 g/L 8-HHME acid for 60 min, with a conversion of 54% (w/w) and a productivity of 4.3 g/L/h; and 0.9 g/L 8-HOME for 30 min, with a conversion of 15% (w/w) and a productivity of 1.8 g/L/h. To best of our knowledge, this is the first report on the biotechnological production of 8,11-DiHODE, 8,11-DiHOTrE, 8-HHME, and 8-HOME. © 2017 American Institute of Chemical Engineers Biotechnol.

Abstract
The first and second preferred substrates of recombinant Escherichia coli cells expressing 10R-dioxygenase (PpoC) from Aspergillus nidulans and the purified enzyme were linoleic acid and α-linolenic acid, respectively. PpoC in cells showed higher thermal and reaction stabilities compared to purified PpoC. Thus, 10R-hydroxy unsaturated fatty acids were produced from linoleic acid, α-linolenic acid, and hempseed oil hydrolyzate containing linoleic acid and α-linolenic acid as substrates by whole recombinant cells expressing PpoC. The optimal reaction conditions for the production of 10R-hydroxy-8E,12Z-octadecadienoic acid (10R-HODE) were pH 8.0, 30 °C, 250 rpm, 5 % (v/v) dimethyl sulfoxide, 5 g l(-1) linoleic acid, and 60 g l(-1) cells in 100-ml baffled flask. Under these conditions, whole recombinant cells expressing PpoC produced 2.7 g l(-1) 10R-HODE from 5 g l(-1) linoleic acid for 40 min, with a conversion yield of 54 % (w/w) and a productivity of 4.0 g l(-1) h(-1); produced 2.2 g l(-1) 10R-hydroxy-8E,12Z,15Z-octadecatrienoic acid (10R-HOTrE) from 3 g l(-1) α-linolenic acid for 30 min, with a conversion yield of 72 % (w/w) and a productivity of 4.3 g l(-1) h(-1); and produced 1.8 g l(-1) 10R-HODE and 0.5 g l(-1) 10R-HOTrE from 5 g l(-1) hempseed oil hydrolyzate containing 2.5 g l(-1) linoleic acid and 1.0 g l(-1) α-linolenic acid for 30 min, with a conversion yield of 74 and 51 % (w/w), respectively, and a productivity of 3.6 and 1.0 g l(-1) h(-1), respectively. To the best of our knowledge, this is the first report on the biotechnological production of 10R-hydroxy unsaturated fatty acids.

Unveiling the genes responsible for the unique Pseudomonas aeruginosa oleate-diol synthase activity. Biochim Biophys Acta Mol Cell Biol Lipids 2014; 1842:1360-71. [PMID: 24980978 DOI: 10.1016/j.bbalip.2014.06.010] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2014] [Revised: 06/16/2014] [Accepted: 06/18/2014] [Indexed: 01/08/2023]
Abstract
Pseudomonas aeruginosa displays the ability to perform bioconversion of oleic acid into a class of hydroxylated fatty acids known as oxylipins. A diol synthase activity is responsible for such a conversion, which proceeds through the dioxygenation of oleic acid to release hydroperoxide 10-H(P)OME ((10S)-hydroxy-(8E)-octadecenoic acid), followed by conversion of the hydroperoxide intermediate into 7,10-DiHOME ((7S,10S)-dihydroxy-(8E)-octadecenoic acid), both of which accumulate in the culture supernatant. Several mutants of P. aeruginosa PAO1 were analyzed for the production of 10-H(P)OME and 7,10-DiHOME and two of them (ORFs PA2077 and PA2078), unable to release hydroxylated fatty acids, were detected and selected for further analysis. Involvement of ORFs PA2077 and PA2078 in oleate-diol synthase activity was confirmed, and their respective role in the conversion of oleic acid was analyzed by mutation complementation. Activity restoration revealed that gene PA2077 codes for the 10S-dioxygenase activity (10S-DOX) responsible for the first step of the reaction, whereas PA2078 encodes for the (7S,10S)-hydroperoxide diol synthase enzyme (7,10-DS) which allows the conversion of 10-H(P)OME into 7,10-DiHOME. Heterologous expression of both enzymes separately showed that no hetero-complex formation is required for enzymatic activity. Bioinformatics and RT-PCR analysis revealed that both genes constitute a new fine regulated oleate-diol synthase operon, originated by a gene duplication event followed by neofunctionalization for environmental adaptation, being unprecedented in prokaryotes.

Abstract
In microorganisms hydroxy fatty acids are produced from the biotransformation of unsaturated fatty acids. Such compounds belong to a class of oxylipins which are reported to perform a variety of biological functions such as anti-inflammatory or cytotoxic activity. These compounds have been found in rice and timothy plants after being infected by specific fungus. When grown in submerged culture with linoleic acid, Pseudomonas 42A2 accumulated in the supernatant several hydroxy fatty acids. In this work LC-MS/MS has been used to elucidate the structure of the components form the organic extract: 9-hydroxy-10,12-octadecadienoic acid; 13-hydroxy-9,11-octadecadienoic acid; 7,10-dihydroxy-8E-octadecenoic acid; 9,10,13-trihydroxy-11-octadecenoic acid and 9,12,13-trihydroxy-10-octadecenoic acid. Antimicrobial activity against several pathogenic fungal strains is presented: MIC (microg/mL) Verticillium dhaliae, 32; Macrophonia phaesolina, 32; Arthroderma uncinatum, 32; Trycophyton mentagrophytes, 64.
