Noncoding RNAs in Host–Microbiota Interaction

open access: yesAnimal Research and One Health, EarlyView.
The intricate interplay between gut microbiota and the host exerts a profound impact on host biological processes and disease development. This review highlights the pivotal role of noncoding RNAs (ncRNAs) in this interaction. Host ncRNAs regulate gene expression and microbiota composition, whereas microbial small RNAs (sRNAs) modulate host gene ...

Unraveling the regulation of pyocyanin synthesis by RsmA through MvaU and RpoS in Pseudomonas aeruginosa ID4365

open access: yesJournal of Basic Microbiology, Volume 63, Issue 1, Page 51-63, January 2023., 2023
Abstract Pyocyanin is a phenazine with redox activity produced by Pseudomonas aeruginosa that is harmful to other bacteria and eukaryotic organisms by generating reactive oxygen species. Gene regulation of pyocyanin synthesis has been addressed in the PAO1 and PA14 strains and involves the three‐quorum sensing systems Las, Rhl, and Pqs; the regulators ...

An Immunosenescent CD8+ T Cell Subset in Patients with Axial Spondyloarthritis and Psoriatic Arthritis Links Spontaneous Motility to Telomere Shortening and Dysfunction

open access: yesArthritis &Rheumatology, EarlyView.
Objective A pathogenetic role of CD8+ T lymphocytes in radiographic axial spondyloarthritis (r‐axSpA) and other spondyloarthritis (SpA) is sustained by genome‐wide association studies and by the expansion of public T cell clonotypes in the target tissues.

Interactive effects of temperature and nitrogen source on the elemental stoichiometry of a polar diatom

open access: yesLimnology and Oceanography, Volume 67, Issue 12, Page 2750-2762, December 2022., 2022
Abstract A recent study hypothesized that the near‐zero temperatures that generally prevail in Arctic waters negate the influence that different nitrogen (N) sources can otherwise have on the growth and elemental stoichiometry of marine micro‐algae. Here we test this hypothesis experimentally by evaluating how temperature (0–9°C) affects the growth and

Construction and Characterization of Novel Shuttle Expression Vectors for Actinobacillus succinogenes

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Actinobacillus succinogenes is a ruminal microorganism of biotechnological importance due to its capacity to produce succinic acid at high yields. Despite the scientific interest in this organism, molecular vehicles for the transfer and expression of genetic material are limited compared to the existing demand.

The contribution of extracellular RNA and its derived biomaterials in disease management

open access: yesBMEMat, EarlyView.
The implications of exRNA's biological function and the structural uniqueness of RNA help establish a close connection between RNA, material, and modern medicine. Abstract The RNA found in the circular system is known as extracellular RNA (exRNA). This kind of RNA has been found to play a biological role similar to that of a messenger. They can be used
