NAD+‐Dependent Enzyme SIRT3 Limits Intestinal Epithelial Cell Functions Through NAD+ Synthesis Pathway in Colorectal Cancer

Advanced Science, EarlyView.
Microbiota‐derived quinolinic acid is used as an alternative source of replenishing the intracellular NAD+ pool induced by SIRT3 deficiency to regulate intestinal epithelial cell and T cell function, which has implications for targeting intestinal epithelial cells as an approach to the treatment of immune‐associated diseases, including colorectal ...

Transformation of 1,1,1-trichloroethane in an anaerobic packed-bed reactor at various concentrations of 1,1,1-trichloroethane, acetate and sulfate [PDF]

, 1997
Biotransformation of 1,1,1-trichloroethane (CH3CCl3) was observed in an anaerobic packed-bed reactor under conditions of both sulfate reduction and methanogenesis. Acetate (1 mM) served as an electron donor.

The Gut Microbiota Regulates Motor Deficits via Butyrate in a Gnal+/− Mouse Model of DYT25 Dystonia

Advanced Science, EarlyView.
The present study provides compelling evidence for a modulatory role of the gut microbiota in the pathology of DYT25 dystonia, and butyrate supplementation alleviates the motor deficits of dystonia in Gnal+/− mice. Abstract Dystonia is the third most common movement disorder, following essential tremor and Parkinson's disease. The underlying mechanisms

Proteomic and Isotopic Response of Desulfovibrio vulgaris to DsrC Perturbation

Frontiers in Microbiology, 2019
Dissimilatory sulfate reduction is a microbial energy metabolism that can produce sulfur isotopic fractionations over a large range in magnitude. Calibrating sulfur isotopic fractionation in laboratory experiments allows for better interpretations of ...

Palmitoylation‐Mediated Ubiquitination of SRPK1 Regulates Ferroptosis in High‐Fat‐Induced Erectile Dysfunction

Advanced Science, EarlyView.
Elevated exogenous palmitic acid promotes the S‐palmitoylation of SRPK1 in endothelial cells, a dynamic process governed by ZDHHC24 and APT1. This post‐translational modification strengthens the interaction between SRPK1 and the E3 ubiquitin ligase MIB1, thereby facilitating the proteasomal degradation of SRPK1.

Effect of Thermophilic Nitrate Reduction on Sulfide Production in High Temperature Oil Reservoir Samples

Frontiers in Microbiology, 2017
Oil fields can experience souring, the reduction of sulfate to sulfide by sulfate-reducing microorganisms. At the Terra Nova oil field near Canada’s east coast, with a reservoir temperature of 95°C, souring was indicated by increased hydrogen sulfide in ...

Fermented Lacticaseibacillus Paracasei Cultures Ameliorate Colitis by Modulating Microbiota‐Derived Tryptophan Metabolism and Macrophage Polarization

Advanced Science, EarlyView.
A solid‐state fermented probiotic (PYW) is developed using wheat bran as substrate, containing high viable Lacticaseibacillus paracasei and bioactive metabolites. PYW alleviates intestinal inflammation by gut microbiota composition, enriching indole derivatives, activating aryl hydrocarbon receptor signaling, and regulating macrophage polarization. PYW
