ProteomicsWidespread cysteine persulfidation in activated macrophages as a protective mechanism against oxidative-inflammatory stress
A hallmark of immune-inflammatory responses is the generation of reactive oxygen and nitrogen species by innate immune cells, in particular macrophages. How macrophages cope with excess oxidant production and associated redox stress is not fully understood. Recent evidence implicates reactive sulfur...

MetabolomicsLactobacillus plantarum MR1 alleviates high-carbohydrate diet-induced oxidative stress and liver lipid deposition via upregulating uridine synthesis
The overconsumption of carbohydrates induces oxidative stress and lipid accumulation in the liver, which can be alleviated by modulation of intestinal microbiota; however, the underlying mechanism remains unclear. Here, we demonstrated that a strain affiliated with Lactobacillus plantarum (de...

TranscriptomicsTranscription profiling of human monocytes (U937 cell line) to assess the impact of curcumin on monocytes exposed to oxidative stress
Oxidative stress as a result of cigarette smoking is an important etiological factor in the pathogenesis of chronic obstructive pulmonary disease (COPD), a chronic steroid-insensitive inflammatory disease of the airways. The activity of the transcriptional co-repressor Histone deacetylase-2 (HDAC2) ...

MetabolomicsMulti-omics reveals taurine-mediated rumen microbial remodeling mitigates high-starch-diet-induced systemic inflammation and oxidative stress in fattening cattle

Background: With the pursuit of rapid intramuscular fat deposition in beef cattle, basal diets have increasingly shifted toward grain-based, energy-dense formulations. However, high-starch dietary regimens may induce host metabolic dysregulation, which is closely linked to both ruminal microbial ...

MetabolomicsChlorogenic acid alters ileal microbiota and metabolites in broilers under immune stress

Immune stress in broilers can cause severe economic losses, chlorogenic acid is an effective plant extract for alleviating immune stress. This study investigates the effect of chlorogenic acid on the intestinal microbiota and metabolites of broilers under immune stress. 312 broilers were randomly...

MetabolomicsPlasma metabolome reveals altered oxidative stress, inflammation, and amino acid metabolism in dogs with idiopathic epilepsy.

OBJECTIVE: Idiopathic epilepsy (IE) is the most common chronic neurological disease in dogs, and an established natural animal model for human epilepsy types with genetic and unknown etiology. However, the metabolic pathways underlying IE remain largely unknown. METHODS: Plasma samples of healthy...

MetabolomicsProbiotics alleviated heat stress-induced spermatogenesis dysfunction by remodeling gut microbiota and producing arginine and pantothenic acid

BACKGROUND: Large-scale farms struggle to effectively address summer heat stress (HS) in dairy goats, which impairs spermatogenesis and reduces reproductive performance by compromising gut and reproductive organ health in male animals. Although Clostridium butyricum (CB) and Enterococcus faecium ...

TranscriptomicsPleiotropic effects of metformin on inflammation, oxidative and dicarbonyl stress in transgenic spontaneously hypertensive rats expressing human C-reactive protein.
Inflammation, oxidative and dicarbonyl stress play important roles in the pathophysiology of type 2 diabetes. Metformin is the first-line drug of choice for the treatment of type 2 diabetes because it effectively suppresses gluconeogenesis in the liver, however, its “pleiotropic“ effects remain cont...

MetabolomicsUntargeted Plasma Lipidomics Identifies Oxidative Stress and Inflammation Signatures Associated with Recurrent Leg Ulcer Status in Sickle Cell Disease

Leg ulcers are among the most burdensome complications of sickle cell disease (SCD), yet the molecular determinants underlying ulcer susceptibility and recurrence remain incompletely characterized. We performed untargeted plasma lipidomics by LC–MS in 129 individuals with SCD from the REDS-III Br...

MetabolomicsFecal microbiota transplantation treatment maintains post antibiotics gut function by change the gut microbiome and fecal metabolome to reduce gut inflammation and oxidative stress in nile tilapia (Oreochromis niloticus)
The imbalance of intestinal flora can affect the immune function and structural integrity of the intestinal barrier, leading to the colonization and reproduction of opportunistic pathogenic bacteria in the intestine to become the dominant flora, eventually inducing enteritis. This study aimed to inv...
