The Sulfolobus solfataricus radA paralogue sso0777 is DNA damage inducible and positively regulated by the Sta1 protein [PDF]

, 2007
Little is known about the regulation of the DNA damage-mediated gene expression in archaea. Here we report that the addition of actinomycin D to Sulfolobus solfataricus cultures triggers the expression of the radA paralogue sso0777.

Chronic alcohol consumption compromises gut barrier integrity and promotes endotoxemia: Implications for sepsis susceptibility in immunocompromised hosts

Animal Models and Experimental Medicine, EarlyView.
Chronic alcohol exposure disrupts intestinal barrier integrity, resulting in a leaky gut and enhanced translocation of lipopolysaccharide (LPS) and microbial products into the systemic circulation. Alcohol‐induced endotoxemia drives exaggerated pro‐inflammatory responses, mitochondrial damage, and activation of the cGAS–STING pathway, particularly in ...

Next Generation DNA-Seq and Differential RNA-Seq Allow Re-annotation of the Pyrococcus furiosus DSM 3638 Genome and Provide Insights Into Archaeal Antisense Transcription

Frontiers in Microbiology, 2019
Pyrococcus furiosus DSM 3638 is a model organism for hyperthermophilic archaea with an optimal growth temperature near 100°C. The genome was sequenced about 18 years ago.

Bioengineering options and strategies for the optimization of anaerobic digestion processes [PDF]

, 2014
Anaerobic digestion (AD) is a complex biological process, and the microbial diversity and dynamics within the reactor needs to be understood and considered when process optimization is sought after.

Beyond PEGylation: Archaeal Lipids for Long‐Circulating Liposomes

Advanced NanoBiomed Research, EarlyView.
Archaeal lipid‐based liposomes, particularly those containing caldarchaeol (GDGT), were found to significantly prolong the circulation time of vancomycin in rats, matching the pharmacokinetic properties of PEGylated systems. These findings suggest archaeal lipids as promising non‐PEG excipients for parenteral applications to minimize drug clearance ...

Conserved substitution patterns around nucleosome footprints in eukaryotes and Archaea derive from frequent nucleosome repositioning through evolution. [PDF]

, 2013
Nucleosomes, the basic repeat units of eukaryotic chromatin, have been suggested to influence the evolution of eukaryotic genomes, both by altering the propensity of DNA to mutate and by selection acting to maintain or exclude nucleosomes in particular ...

Identification of XylR, the Activator of Arabinose/Xylose Inducible Regulon in Sulfolobus acidocaldarius and Its Application for Homologous Protein Expression

Frontiers in Microbiology, 2020
The thermophilic archaeon Sulfolobus acidocaldarius can use different carbon sources for growth, including the pentoses D-xylose and L-arabinose. In this study, we identified the activator XylR (saci_2116) responsible for the transcriptional regulation ...

An Lrs14 family protein functions as a nucleoid-associated protein regulating cell cycle progression in Sulfolobales

Communications Biology
Archaea of the order Sulfolobales possess eukaryotic-like cell cycle. The chromatin organization in these archaea is supposed to rely on nucleoid-associated proteins (NAPs).

Effects of Lycium barbarum Residue Substituting Dietary Maize on Fecal Microbiota and Growth Performance of Crossbred Simmental Cattle

Animal Research and One Health, EarlyView.
The bioactive substances we extracted from Lycium barbarum residue (LBR) have a typical polysaccharide structure. When 1.80% LBR was used to replace maize in the diet, the average daily gain of rossbred Simmental was significantly increased, and anti‐inflammatory ability was improved. In addition, LBR improved the fecal microbial composition, increased
