SOS-Inducing Drugs Trigger Nucleic Acid Release and Biofilm Formation in Gram-Negative Bacteria

open access: yesBiomolecules
Our laboratory recently reported that induction of the SOS response, triggered by SOS-inducing drugs, was accompanied by a large release of DNA from enteric bacteria.

The SOS response of Listeria monocytogenes is involved in stress resistance and mutagenesis [PDF]

open access: yes
The SOS response is a conserved pathway that is activated under certain stress conditions and is regulated by the repressor LexA and the activator RecA.

A DNA Damage-Induced, SOS-Independent Checkpoint Regulates Cell Division in Caulobacter crescentus [PDF]

open access: yes, 2014
Cells must coordinate DNA replication with cell division, especially during episodes of DNA damage. The paradigm for cell division control following DNA damage in bacteria involves the SOS response where cleavage of the transcriptional repressor LexA ...

Bacteriophage induction versus vaginal homeostasis: Role of H2O2 in the selection of Lactobacillus defective prophages [PDF]

open access: yes, 2009
Vaginal disorders associated with systemic chemotherapy arise by direct inhibition of the resident microbiota (dominated by lactobacilli) or, possibly, by induction of prophages harbored in their genomes, leading to cell lysis.

Responsiveness and construct validity of a symptom scale for acute otitis media [PDF]

open access: yes, 2008
BACKGROUND:: Because resolution of symptoms is a primary goal of antimicrobial therapy in children with acute otitis media (AOM), measurement of symptoms in studies of antimicrobial effectiveness in such children is important.

Lipocalin‐2 activates hepatic stellate cells and promotes nonalcoholic steatohepatitis in high‐fat diet–fed Ob/Ob mice

open access: yesHepatology, EarlyView., 2022
Graphical summary of obesity‐induced NASH progression by LCN2 targeted to HSC activation. Abstract Background and Aims In obesity and type 2 diabetes mellitus, leptin promotes insulin resistance and contributes to the progression of NASH via activation of hepatic stellate cells (HSCs).

RpoS plays a central role in the SOS induction by sub-lethal aminoglycoside concentrations in Vibrio cholerae. [PDF]

open access: yesPLoS Genetics, 2013
Bacteria encounter sub-inhibitory concentrations of antibiotics in various niches, where these low doses play a key role for antibiotic resistance selection.

A qnr-plasmid allows aminoglycosides to induce SOS in Escherichia coli

open access: yeseLife, 2022
The plasmid-mediated quinolone resistance (PMQR) genes have been shown to promote high-level bacterial resistance to fluoroquinolone antibiotics, potentially leading to clinical treatment failures.

Postantibiotic SOS response states in E. coli intestinal microbiocenoses and their possible consequences (review)

open access: yesВетеринария и кормление
The study of the effects of stress on E. coli in the intestine, realized through SOS-response reactions, is important for understanding the possible consequences for microbiocenoses.

Comparison of Phenological Parameters Extracted from SIF, NDVI and NIRv Data on the Mongolian Plateau

open access: yesRemote Sensing, 2022
The phenological parameters estimated from different data may vary, especially in response to climatic factors. Therefore, we estimated the start of the growing season (SOS) and the end of the growing season (EOS) based on sunlight-induced chlorophyll ...
