Abstract
BACKGROUND It has been found that a variety of host disease states can exacerbate intestinal inflammation, leading to disruption of intestinal barrier function. Changes in the composition of the intestine microbiota, which affect downstream metabolites in turn, ultimately react against the host. OBJECTIVES We revealed the mechanism of berberine as an intestinal protective agent in rats with renal ischemia-reperfusion injury acute kidney injury (AKI). METHODS HE staining was performed to evaluate the pathological changes in the colon and kidney. 16 S rRNA analysis was performed to assess the intestinal microbiota. Intestine TLR4/NF-κB expression was assessed by western blot. Q-RT-PCR was performed to detect TLR4 in intestine and IL-6 and KIM-1 gene expression in the kidney. SPSS 22.0 was used to compare the data. RESULTS Rats with AKI exhibited increased relative abundances of Proteobacteria and Bacteroidetes and decreased relative abundances of Lactobacillus, Ruminococcus and Lachnospiraceae belonging to the phylum Firmicutes. The Sirt1-NF-κB-TLR4 pathway was involved in the occurrence process, accompanied by intestinal inflammation and oxidation. Berberine reversed the appeal change. CONCLUSION Berberine inhibits the intestinal biological barrier of Proteobacteria, reduces LPS production, exerts an anti-inflammatory effect, and delays the progression of AKI.

Physiol Res 2023; 72:511-520. [PMID: 37795893 PMCID: PMC10634562 DOI: 10.33549/physiolres.935040] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Accepted: 04/18/2023] [Indexed: 01/05/2024] Open
Abstract
Farrerol (FA) is a traditional Chinese herbal medicine known for its anti-inflammatory and anti-oxidative properties in various diseases. Ferroptosis is an iron-dependent oxidative stress-induced cell death. It is characterized by lipid peroxidation and glutathione depletion and is involved in neuronal injury. However, the role of FA in inhibiting ferroptosis in hypoxic-ischemic encephalopathy (HIE) and its underlying mechanisms are not yet completely elucidated. This study aimed to investigate whether FA could mediate ferroptosis and explore its function and molecular mechanism in HIE. A neonatal rat model of HIE was used, and rats were treated with FA, ML385 (a specific inhibitor of nuclear factor erythroid 2-related factor 2 [Nrf2]), or a combination of both. Neurological deficits, infarction volume, brain water content, pathological changes, and iron ion accumulation in the brain tissues were measured using the Zea-Longa scoring system and triphenyl tetrazolium chloride (TTC), hematoxylin-eosin (HE), and Perls' staining. The expression levels of GSH-Px, MDA, SOD, and ROS in brain tissues were also evaluated. Western blot analysis was performed to analyze the expression of the Nrf2 pathway and ferroptosis-related proteins. The results showed that FA administration significantly reduced neuronal damage, infarct volume, cerebral edema, and iron ion accumulation and inhibited MDA and ROS levels while promoting GSH-Px and SOD levels. FA also increased the expression levels of glutathione peroxidase 4 (GPX4), solute carrier family 7 member 11 (SLC7A11), Nrf2, and HO-1. Moreover, the combination of ML385 and FA in HIE abolished the FA protective effects. Therefore, the study concludes that FA exerts a neuroprotective effect after HIE by inhibiting oxidative stress and ferroptosis via the Nrf2 signaling pathway.

Abstract
Mycotoxin-induced liver injury is often accompanied by oxidative stress (OS) and inflammation. This research aimed to explore the potential mechanism of sodium butyrate (NaBu) in modulating hepatic anti-oxidation and anti-inflammation pathways in deoxynivalenol (DON)-exposed piglets. The results show that DON induced liver injury, increased mononuclear cell infiltration, and decreased serum total protein and albumin concentrations. Transcriptomic analysis revealed that reactive oxygen species (ROS) and TNF-α pathways were highly activated upon DON exposure. This is associated with disturbed antioxidant enzymes and increased inflammatory cytokines secretion. Importantly, NaBu effectively reversed the alterations caused by DON. Mechanistically, the ChIP-seq result revealed that NaBu strongly depressed DON-increased enrichment of histone mark H3K27ac at the genes involved in ROS and TNF-α-mediated pathways. Notably, we demonstrated that nuclear receptor NR4A2 was activated by DON and remarkably recovered with the treatment of NaBu. In addition, the enhanced NR4A2 transcriptional binding enrichments at the promoter regions of OS and inflammatory genes were hindered by NaBu in DON-exposed livers. Consistently, elevated H3K9ac and H3K27ac occupancies were also observed at the NR4A2 binding regions. Taken together, our results indicated that a natural antimycotic additive, NaBu, could mitigate hepatic OS and inflammatory responses, possibly via NR4A2-mediated histone acetylation.

Abstract
Lumbosacral spinal root avulsion (LSRA) is a severe nerve injury that results in devastating dysfunction in the lower limb. Circular ribonucleic acids (circRNAs) have been reported to be implicated in a variety of diseases. However, the role of circRNAs in LSRA remains unclear. Here, we performed RNA sequencing (RNA-seq) to determine circRNA expression profiles in a rat LSRA model and further investigated their potential functions and the underlying mechanisms by bioinformatic analyses and in vitro experiments. In all, 1708 circRNAs were found to be differentially expressed in spinal cord tissues after LSRA (|fold change| ≥ 2 and p < 0.05), with 591 up-regulated 1117 down-regulated. Meanwhile, 2263 mRNAs were also indentified to be differentially expressed, of which 1471 were upregulated and 792 were downregulated. Eight randomly selected circRNAs and mRNA were successfully verified to be consistent the RNA-seq results by quantitative real-time polymerase chain reaction. Functional analyses based on gene ontology and Kyoto Encyclopedia of Genes and Genomes predicted the potential roles of differentially expressed circRNAs and mRNAs in LSRA, and circRNA/miRNA/mRNA interaction networks revealed that circRNA_7025, a down-regulated circRNA in LSRA, was targeted by two neuronal apoptosis-related miRNAs, rno-miR-1224 and rno-miR-326-5p. Further in vitro experiments revealed that circRNA_7025 protected against oxygen-glucose deprivation induced neuronal apoptosis via the circRNA_7025/miR-1224/miR-326-5p axis. In summary, our results revealed circRNA expression profiles and their potential functions in LSRA. These findings improve our understanding of the pathogenic mechanisms involved in LSRA and might enable us to identify new molecular targets for LSRA.
