MetabolomicsButyric acid derived from porcine-derived antioxidant probiotic PGM326 enhances intestinal cell differentiation by promoting oxidative phosphorylation

This study not only identified an efficient host-homologous antioxidant probiotic, PGM326, but also systematically elucidated its mechanism of exerting antioxidant function by synthesizing BA to promote OXPHOS in intestinal epithelial cells, thereby enhancing cell differentiation. This provides a...

MetabolomicsInitial exploration of the health effects on Qinghai-Tibetan Plateau yaks following short-term exposure to polystyrene microplastics: analysis of rumen microbiota, host metabolism, antioxidant function and inflammatory responses.

Abstract: Microplastics (MPs) are omnipresent in the environment, including the Qinghai-Tibet Plateau. Previous research on MPs has primarily focused on aquatic species and rodents, with little known about their impact on yaks. This study introduced yak as an animal model, employing a combin...

MetabolomicsRectal microbiomes and serum metabolomics reveal changes in serum antioxidant status and immune responses of Dezhou donkeys in late gestation to parturition

Background: Parturition is a critical event in the reproductive cycle of dairy animals, accompanied by multiple physiological changes in sex hormones, metabolism, antioxidant capacity and immune function. However, the changes in the rectal microbiota and metabolic products of Jennies from late ge...

Metabolomics3,4-Dihydroxybenzaldehyde exerts anti-Alzheimer's effects by inhibiting Aβ protofibril assembly and activating antioxidant defense mechanisms

Broad-spectrum metabolomic analyses reveal that DBD markedly modulates the nematode’s metabolic profile. DBD enhances the activation of transcription factors DAF-16/FOXO and SKN-1/Nrf2, increasing resistance to oxidative and thermal stress. These findings suggest that DBD possesses multi-target t...

MetabolomicsMulti-Omic Analysis and Platelet Function Distinguish Treatment Responses to Hydroxytyrosol in Cardiovascular Risk
Many polyphenols have been recognized for their antioxidant and health benefits. The present study attempted, for the first time, to determine the effects of daily oral intake of β-cyclodextrin-encapsulated hydroxytyrosol (HT) on plasma platelet reactivity and proteomic and metabolomic profiles of p...

MetabolomicsNorgestrel exposure accelerated the abnormal occurrence of germinal vesicle breakdown and triggered damage to cellular structure and function in oocytes of the Pacific oyster (Crassostrea gigas)

Progestins are ubiquitous in aquatic environments, with adverse effects on aquatic organisms' reproduction even at extremely low concentrations (0.8 ng/L). As female germ cells, oocytes play an irreplaceable role in organismal reproductive processes. However, the toxic mechanism of norgestrel (NG...

TranscriptomicsNAC, Tiron and Trolox impair GBM tumorigenic cell survival by mechanisms independent from antioxidant activity
The aim of this study is to determine if, using antioxidant drugs, it is possible to interfere with the proliferative capabilities of the human glioblastoma (GBM) tumor-initiating cells (TICs). To establish which cellular processes are activated in GBM TICs by the antioxidants NAC, Tiron and Trolox,...

ProteomicsHypoxia reveals the new function of Foxn1 in keratinocytes antioxidant defense system
Skin exposed to environmental threats including injuries and oxidative stress developed an efficient but not fully recognized systems of repair and antioxidant protection. In this project we provide evidence that Foxn1 in keratinocytes regulates elements of electron transport chain and participates ...
