Effect of shear stress on Pseudomonas aeruginosa isolated from the cystic fibrosis lung [PDF]
Chronic colonization of the lungs by Pseudomonas aeruginosa is one of the major causes of morbidity and mortality in cystic fibrosis (CF) patients. To gain insights into the characteristic biofilm phenotype of P. aeruginosa in the CF lungs, mimicking the

Role of the Sinorhizobium meliloti Global Regulator Hfq in Gene Regulation and Symbiosis
The RNA-binding protein Hfq is a global regulator which controls diverse cellular processes in bacteria. To begin understanding the role of Hfq in the Sinorhizobium meliloti–Medicago truncatula nitrogen-fixing symbiosis, we defined free-living and ...

Reduced heme levels underlie the exponential growth defect of the Shewanella oneidensis hfq mutant. [PDF]
The RNA chaperone Hfq fulfills important roles in small regulatory RNA (sRNA) function in many bacteria. Loss of Hfq in the dissimilatory metal reducing bacterium Shewanella oneidensis strain MR-1 results in slow exponential phase growth and a reduced ...

Chromatin and gene regulation in archaea
Recent data from diverse archaea with different repertoires of nucleoid‐associated proteins show a common genome‐wide chromatin organisation where chromatin maintains access to gene promoters independently of transcription activity. Abstract The chromatinisation of DNA by nucleoid‐associated proteins (NAPs) in archaea ‘formats’ the genome structure in ...

Orthogonality of Hermite polynomials in superspace and Mehler type formulae [PDF]
In this paper, Hermite polynomials related to quantum systems with orthogonal O(m)-symmetry, finite reflection group symmetry G < O(m), symplectic symmetry Sp(2n) and superspace symmetry O(m) x Sp(2n) are considered.

Hfq proximity and orientation controls RNA annealing [PDF]
Regulation of bacterial gene networks by small non-coding RNAs (sRNAs) requires base pairing with messenger RNA (mRNA) targets, which is facilitated by Hfq protein. Hfq is recruited to sRNAs and mRNAs through U-rich- and A-rich-binding sites, respectively, but their distance from the sRNA-mRNA complementary region varies widely among different genes ...

Role of the Bacterial Amyloid-like Hfq in Fluoroquinolone Fluxes
Due to their two-cell membranes, Gram-negative bacteria are particularly resistant to antibiotics. Recent investigations aimed at exploring new target proteins involved in Gram-negative bacteria adaptation helped to identify environmental changes encountered during infection.

Paclitaxel induces DNMT3a‐dependent DNA hypomethylation in the mPFC, which contributes to paclitaxel‐induced hyperalgesia and anxiety by upregulating GABAA receptors and enhancing inhibitory transmission in mPFC glutamatergic neurons. Strategies that increase DNA methylation, such as a long‐term methyl donor diet, may offer benefits for managing ...

This study investigates the green synthesis of zinc oxide nanoparticles (ZnO NPs) using the aqueous extract of the aquatic plant Spirodela polyrhiza (greater duckweed) and evaluates their multifunctional properties. The ZnO NPs were synthesized via a sustainable method and characterized using UV‐visible spectroscopy, TEM, FESEM, EDX, FTIR, and XRD ...

Functional Characterization of the RNA Chaperone Hfq in the Opportunistic Human Pathogen Stenotrophomonas maltophilia. [*Roscetto M, *Angrisano T, co-first authors]. [PDF]
Hfq is an RNA-binding protein known to regulate a variety of cellular processes by interacting with small RNAs (sRNAs) and mRNAs in prokaryotes. Stenotrophomonas maltophilia is an important opportunistic pathogen affecting primarily hospitalized and ...
