Transcriptional Regulation of the Equol Biosynthesis Gene Cluster in Adlercreutzia Equolifaciens DSM19450T
Article Transcriptional Regulation of the Equol Biosynthesis Gene Cluster in Adlercreutzia equolifaciens DSM19450T Ana Belén Flórez 1,*, Lucía Vázquez 1, Javier Rodríguez 1, Begoña Redruello 2 and Baltasar Mayo 1 1 Departamento de Microbiología y Bioquímica, Instituto de Productos Lácteos de Asturias (IPLA-CSIC), Paseo Río Linares s/n, Villaviciosa, 33300 Asturias, Spain; [email protected] (L.V.); [email protected] (J.R.); [email protected] (B.M.) 2 Servicios Científico-Técnicos, Instituto de Productos Lácteos de Asturias (IPLA-CSIC), Paseo Río Linares s/n, Villaviciosa, 33300 Asturias, Spain; [email protected] * Correspondence: [email protected]; Tel.: +34-985-89-21-31 Received: 25 February 2019; Accepted: 30 April 2019; Published: 30 April 2019 Abstract: Given the emerging evidence of equol’s benefit to human health, understanding its synthesis and regulation in equol-producing bacteria is of paramount importance. Adlercreutzia equolifaciens DSM19450T is a human intestinal bacterium —for which the whole genome sequence is publicly available— that produces equol from the daidzein isoflavone. In the present work, daidzein (between 50 to 200 μM) was completely metabolized by cultures of A. equolifaciens DSM19450T after 10 h of incubation. However, only about one third of the added isoflavone was transformed into dihydrodaidzein and then into equol. Transcriptional analysis of the ORFs and intergenic regions of the bacterium’s equol gene cluster was therefore undertaken using RT-PCR and RT-qPCR techniques with the aim of identifying the genetic elements of equol biosynthesis and its regulation mechanisms. Compared to controls cultured without daidzein, the expression of all 13 contiguous genes in the equol cluster was enhanced in the presence of the isoflavone. -

ABSTRACT OF DISSERTATION Andres Enrique Nunez The Graduate School University of Kentucky 2008 MICROBIAL COMMUNITY STRUCTURE DYNAMICS IN OHIO RIVER SEDIMENTS DURING REDUCTIVE DECHLORINATION OF PCBS ABSTRACT OF DISSERTATION A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the College of Agriculture at the University of Kentucky By Andres Enrique Nunez Director: Dr. Elisa M. D’Angelo Lexington, KY 2008 Copyright © Andres Enrique Nunez 2008 ABSTRACT OF DISSERTATION MICROBIAL COMMUNITY STRUCTURE DYNAMICS IN OHIO RIVER SEDIMENTS DURING REDUCTIVE DECHLORINATION OF PCBS The entire stretch of the Ohio River is under fish consumption advisories due to contamination with polychlorinated biphenyls (PCBs). In this study, natural attenuation and biostimulation of PCBs and microbial communities responsible for PCB transformations were investigated in Ohio River sediments. Natural attenuation of PCBs was negligible in sediments, which was likely attributed to low temperature conditions during most of the year, as well as low amounts of available nitrogen, phosphorus, and organic carbon. -

Daidzein Intake Is Associated with Equol Producing Status Through an Increase in the Intestinal Bacteria Responsible for Equol Production
Article Daidzein Intake Is Associated with Equol Producing Status through an Increase in the Intestinal Bacteria Responsible for Equol Production Chikara Iino 1, Tadashi Shimoyama 2,*, Kaori Iino 3, Yoshihito Yokoyama 3, Daisuke Chinda 1, Hirotake Sakuraba 1, Shinsaku Fukuda 1 and Shigeyuki Nakaji 4 1 Department of Gastroenterology, Hirosaki University Graduate School of Medicine, Hirosaki 036-8562, Japan; [email protected] (C.I.); [email protected] (D.C.); [email protected] (H.S.); [email protected] (S.F.) 2 Aomori General Health Examination Center, Aomori 030-0962, Japan 3 Department of Obstetrics and Gynecology, Hirosaki University Graduate School of Medicine, Hirosaki 036-8562, Japan; [email protected] (K.I.); [email protected] (Y.Y.) 4 Department of Social Medicine, Hirosaki University Graduate School of Medicine, Hirosaki 036-8562, Japan; [email protected] * Correspondence: [email protected]; Tel.: +81-017-741-2336 Received: 9 January 2019; Accepted: 7 February 2019; Published: 19 February 2019 Abstracts: Equol is a metabolite of isoflavone daidzein and has an affinity to estrogen receptors. Although equol is produced by intestinal bacteria, the association between the status of equol production and the gut microbiota has not been fully investigated. The aim of this study was to compare the intestinal bacteria responsible for equol production in gut microbiota between equol producer and non-producer subjects regarding the intake of daidzein. A total of 1044 adult subjects who participated in a health survey in Hirosaki city were examined. The concentration of equol in urine was measured by high-performance liquid chromatography. -

However, despite its importance, the chicken gut microbiome remains largely undefined. Here, we exploit culture-independent and culture-dependent approaches to reveal extensive taxonomic diversity within this complex microbial community. Results: We performed metagenomic sequencing of fifty chicken faecal samples from Submitted 4 December 2020 two breeds and analysed these, alongside all (n = 582) relevant publicly available Accepted 22 January 2021 chicken metagenomes, to cluster over 20 million non-redundant genes and to Published 6 April 2021 construct over 5,500 metagenome-assembled bacterial genomes. -

Accumulating evidence suggests that gut microbiota Depression via the gut-brain axis play a role in the pathogenesis of depression, thereby contributing to the antidepressant Lipopolysaccharide actions of certain compounds. Here we investigated the role of gut microbiota in the antidepressant effects of Gut microbiota ketamine in lipopolysaccharide (LPS)-induced inflammation model of depression. Ketamine (10 mg/kg) sig- nificantly attenuated the increased immobility time in forced swimming test (FST), which was associated with the improvements in α-diversity, consisting of Shannon, Simpson and Chao 1 indices. In addition to α-diversity, β-diversity, such as principal coordinates analysis (PCoA), and linear discriminant analysis (LDA) coupled with effect size measurements (LEfSe), showed a differential profile after ketamine treatment. -
