Combined proteomics and metabolomics analysis reveal the effect of a training course on the immune function of Chinese elite short‐track speed skaters

open access: yesImmunity, Inflammation and Disease, Volume 12, Issue 10, October 2024.
One training course stimulates the immune response, and this reaction can be significantly reflected in urine. Moreover, the osteopontin (OPN)/CD44 pathway may be a potential indicator for training load in elite short track speed skaters. Abstract Introduction The aim of this study was to combine proteomics and metabolomics to evaluate the immune ...

Phenotypic and genotypic characterization of peptidoglycan hydrolases of Lactobacillus sakei

open access: yesJournal of Advanced Research, 2016
Lactobacillus sakei, a lactic acid bacterium naturally found in fresh meat and sea products, is considered to be one of the most important bacterial species involved in meat fermentation and bio-preservation. Several enzymes of Lb.

Bacterial Cell Enlargement Requires Control of Cell Wall Stiffness Mediated by Peptidoglycan Hydrolases. [PDF]

open access: yes, 2015
Most bacterial cells are enclosed in a single macromolecule of the cell wall polymer, peptidoglycan, which is required for shape determination and maintenance of viability, while peptidoglycan biosynthesis is an important antibiotic target.

Influence of microbiota on the growth and gene expression of Clostridioides difficile in an in vitro coculture model

open access: yesMicrobiologyOpen, Volume 13, Issue 5, October 2024.
The presence of microbiota did not affect the growth of Clostridioides difficile in this study. However, it did influence the expression of C. difficile genes related to sporulation, germination, and virulence, which are crucial for the transmission of the pathogen. In the presence of microbiota, C.

Purification and Partial Characterization of a Novel Bacteriocin Synthesized by Lactobacillus paracasei HD1-7 Isolated from Chinese Sauerkraut Juice

open access: yesScientific Reports, 2016
Bacteriocins have antimicrobial activities against food-spoiling bacteria and food-borne pathogens. Paracin 1.7, a bacteriocin synthesized by Lactobacillus paracasei HD1-7 isolated from Chinese sauerkraut juice, was studied.

Alkaline shock protein 23 (Asp23)‐controlled cell wall imbalance promotes membrane vesicle biogenesis in Staphylococcus aureus

open access: yesJournal of Extracellular Vesicles, Volume 13, Issue 9, September 2024.
Abstract Membrane vesicles (MVs) are produced by species across all domains of life and have diverse physiological functions as well as promising applications. While the mechanisms for vesiculation in Gram‐negative bacteria are well‐established, the genetic determinants and regulatory factors responsible for MV biogenesis in Gram‐positive bacteria ...

Comparative genomics of four closely related Clostridium perfringens bacteriophages reveals variable evolution among core genes with therapeutic potential

open access: yesBMC Genomics, 2011
Background Because biotechnological uses of bacteriophage gene products as alternatives to conventional antibiotics will require a thorough understanding of their genomic context, we sequenced and analyzed the genomes of four closely related phages ...

Plasticity for the win: Flexible transcriptional response to host plant switches in the comma butterfly (Polygonia c‐album)

open access: yesMolecular Ecology, Volume 33, Issue 16, August 2024.
Abstract Generalist plant‐feeding insects are characterised by a broad host repertoire that can comprise several families or even different orders of plants. The genetic and physiological mechanisms underlying the use of such a wide host range are still not fully understood.

The effect of altered pH growth conditions on the production, composition, and proteomes of Helicobacter pylori outer membrane vesicles

open access: yesPROTEOMICS, Volume 24, Issue 11, June 2024.
Abstract Gram‐negative bacteria release outer membrane vesicles (OMVs) that contain cargo derived from their parent bacteria. Helicobacter pylori is a Gram‐negative human pathogen that produces urease to increase the pH of the surrounding environment to facilitate colonization of the gastric mucosa.

The Molecular basis of N-acetylmuramoyl-L-alanine amidase (Rv3915) and Protein Kinase B (PknB) essentiality in Mycobacterium tuberculosis

open access: yes, 2019
Abstract Background: Protein kinase B (PknB) is critical for the survival of Mycobacterium tuberculosis (M. tuberculosis) in vitro and in hosts. It phosphorylates various enzymes involved in biosynthesis of cell wall and a particular autolysin classified as CwIM or Rv3915 has been recently identified as a PknB substrate.
