Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

open access: yesFEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

Cold Shock as a Screen for Genes Involved in Cold Acclimatization in Neurospora crassa

open access: yesG3: Genes, Genomes, Genetics, 2018
When subjected to rapid drops of temperature (cold shock), Neurospora responds with a temporary shift in its morphology. This report is the first to examine this response genetically.

Salmonella enterica serovar typhi limits the potency of typhoid toxin and ADP‐ribosylating toxin AB to establish a persistent infection

open access: yesFEBS Open Bio, EarlyView.
The two catalytic subunits of typhoid toxin dissociate from the holotoxin in the ER of an intoxicated cell, but only CdtB exits the ER to generate immunosuppressive effects. PltA is retained in the ER and sequestered from its cytosolic target, thus allowing the anti‐inflammatory effects of CdtB to promote intestinal colonization.

Rumen Microbiome and Metabolome of Tibetan Sheep (Ovis aries) Reflect Animal Age and Nutritional Requirement

open access: yesFrontiers in Veterinary Science, 2020
The rumen microbiota plays an important role in animal functional attributes. These microbes are indispensable for the normal physiological development of the rumen, and may also convert the plant polysaccharides from grass into available milk and meat ...

Cell surface CD11c as a neutrophil aging marker molecule

open access: yesFEBS Open Bio, EarlyView.
Cell surface CD11chi neutrophils were more aged and had better phagocytic function than CD11c−/lo neutrophils. Transcriptomic analysis of CD11chi neutrophils and CD11c−/lo neutrophils in pediatric population showed that the most difference was seen in infants.

SCIENCE CHINA Psychrotolerant methanogenic archaea: Diversity and cold adaptation mechanisms

open access: yes, 2020
Because of their diversity and abundance in a wide range of environments, particularly in cold regions, cold-adaptive archaea are expected to play a pivotal role in material recycling in cold environments. Methanogenic archaea are ubiquitous on earth and

Climate change adaptation in the boardroom [PDF]

open access: yes, 2013
Climate adaptation is recognised by many of the world’s largest businesses as a global risk and one that requires critical attention. The World Economic Forum’s 2013 Global Risks Perception Survey, identified the ‘failure of climate change adaptation and

Metabolite profiling of the cold adaptation of Pseudomonas putida KT2440 and cold‐sensitive mutants [PDF]

open access: yes, 2019
peer reviewedFree-living bacteria such as Pseudomonas putida are frequently exposed to temperature shifts and non-optimal growth conditions. We compared the transcriptome and metabolome of the cold adaptation of Pseudomonas putida KT2440 and isogenic ...

Comparative analysis of membrane lipids in psychrophilic and mesophilic freshwater dinoflagellates

open access: yesFrontiers in Plant Science, 2016
Here we report the lipid profiles of ten dinoflagellate species originating from different freshwater habitats and grown at 4, 13 or 20°C akin to their natural occurrence.

BCG vaccination potentiates oxidative phosphorylation in neonatal myeloid‐derived suppressor cells

open access: yesFEBS Open Bio, EarlyView.
BCG vaccination enhances oxidative phosphorylation in neonatal MDSCs, impairing their immunosuppressive function. It upregulates electron transport chain genes and mitochondrial activity, increasing ATP and oxygen consumption. Pharmacological OXPHOS inhibition partially restores suppressive capacity, confirming causality.
