Microbiota metabolites in health and disease

JL McCarville, GY Chen, VD Cuevas… - Annual review of …, 2020 - annualreviews.org
Metabolism is one of the strongest drivers of interkingdom interactions—including those
between microorganisms and their multicellular hosts. Traditionally thought to fuel energy …

[HTML][HTML] Cooperative metabolic adaptations in the host can favor asymptomatic infection and select for attenuated virulence in an enteric pathogen

KK Sanchez, GY Chen, AMP Schieber, SE Redford… - Cell, 2018 - cell.com
Pathogen virulence exists on a continuum. The strategies that drive symptomatic or asymptomatic
infections remain largely unknown. We took advantage of the concept of lethal dose …

[HTML][HTML] The Listeria monocytogenes PASTA Kinase PrkA and Its Substrate YvcK Are Required for Cell Wall Homeostasis, Metabolism, and Virulence

DA Pensinger, KM Boldon, GY Chen… - PLoS …, 2016 - journals.plos.org
Obstacles to bacterial survival and replication in the cytosol of host cells, and the mechanisms
used by bacterial pathogens to adapt to this niche are not well understood. Listeria …

Pseudomonas putida F1 has multiple chemoreceptors with overlapping specificity for organic acids

RE Parales, RA Luu, GY Chen, X Liu, V Wu… - …, 2013 - microbiologyresearch.org
Previous studies have demonstrated that Pseudomonas putida strains are not only capable
of growth on a wide range of organic substrates, but also chemotactic towards many of these …

Listeria monocytogenes cytosolic metabolism promotes replication, survival, and evasion of innate immunity

GY Chen, DA Pensinger, JD Sauer - Cellular microbiology, 2017 - Wiley Online Library
Listeria monocytogenes , the causative agent of listeriosis, is an intracellular pathogen that
is exquisitely evolved to survive and replicate in the cytosol of eukaryotic cells. Eukaryotic …

Role of respiratory NADH oxidation in the regulation of Staphylococcus aureus virulence

…, AM Lencina, JN Radin, GY Chen… - EMBO …, 2020 - embopress.org
The success of Staphylococcus aureus as a pathogen is due to its capability of fine‐tuning
its cellular physiology to meet the challenges presented by diverse environments, which …

[PDF][PDF] Emergence of novel genomic regulatory regions associated with light-organ development in the bobtail squid

L Rouressol, J Briseno, N Vijayan, GY Chen… - Iscience, 2023 - cell.com
Light organs (LO) with symbiotic bioluminescent bacteria are hallmarks of many bobtail
squid species. These organs possess structural and functional features to modulate light, …

A Genetic Screen Reveals that Synthesis of 1,4-Dihydroxy-2-Naphthoate (DHNA), but Not Full-Length Menaquinone, Is Required for Listeria monocytogenes …

GY Chen, CE McDougal, MA D'Antonio, JL Portman… - MBio, 2017 - Am Soc Microbiol
Through unknown mechanisms, the host cytosol restricts bacterial colonization; therefore,
only professional cytosolic pathogens are adapted to colonize this host environment. Listeria …

Listeria monocytogenes MenI encodes a DHNA-CoA thioesterase necessary for menaquinone biosynthesis, cytosolic survival, and virulence

HB Smith, TL Li, MK Liao, GY Chen, Z Guo… - Infection and …, 2021 - Am Soc Microbiol
Listeria monocytogenes is a Gram-positive, intracellular pathogen that is highly adapted to
invade and replicate in the cytosol of eukaryotic cells. Intermediate metabolites in the …

[HTML][HTML] Beyond tug-of-war: iron metabolism in cooperative host–microbe interactions

GY Chen, JS Ayres - PLoS Pathogens, 2020 - journals.plos.org
Infections induce dramatic rearrangements in host macro-and micronutrient processes [1]
and likely reflect host adaptive mechanisms to defend against infection. Traditional models to …
