Project description:This study determined the genes that are differentially expressed when regulatory T cells (Tregs) were isolated from the lamina propria of the small and large intestine from mice with impaired IL-2Rβ signaling (designated Y3) or impaired IL-2Rβ signaling and lack of CD103 expression (designated Y3/CD103-/-) when compared to Tregs from WT mice. 204 unique annotated mRNAs were differentially expressed by ≥1.5 fold between these 3 groups (Fig. 6B). Very few mRNAs were uniquely up or down regulated in relationship to impaired IL-2Rβ signaling or the combination of impaired IL-2Rβ signaling and lack of CD103 expression. Thus, lack of CD103 does not obviously regulated signaling in Tregs in the gut mucosa and most differentially expressed genes were due to impaired IL_2Rβ signaling. Gene enrichment analysis of these differentially expressed genes identified 4 major enrichment groups (EG) are: EG1, Cytokine-cytokine receptor interaction and the JAK-STAT signaling pathway; EG2, regulation of lymphocyte activation and proliferation; EG3, regulation of cell death and the caspase pathway in apoptosis; and EG4, transcription. Mouse regulatory T cells (Tregs) cells were FACS purified based on expression of red fluorescent protein linked to the Foxp3 gene. These cells were obtained from the lamina propria of the small and large intestine from WT, Y3, and Y3/CD103-/- mice. Total RNA was prepared and processed to probe Affymetrix mouse Gene ST2.0 arrays.

Project description:Acetaminophen is a widely used antipyretic and analgesic drug, and its overdose is the leading cause of drug-induced acute liver failure. This study aimed to investigate the effect and mechanism of Lacticaseibacillus casei Shirota (LcS), an extensively used and highly studied probiotic, on acetaminophen-induced acute liver injury. C57BL/6 mice were gavaged with LcS suspension or saline once daily for 7 days before the acute liver injury was induced via intraperitoneal injection of 300 mg/kg acetaminophen. The results showed that LcS significantly decreased acetaminophen-induced liver and ileum injury, as demonstrated by reductions in the increases in aspartate aminotransferase, total bile acids, total bilirubin, indirect bilirubin and hepatic cell necrosis. Moreover, LcS alleviated the acetaminophen-induced intestinal mucosal permeability, elevation in serum IL-1α and lipopolysaccharide, and decreased levels of serum eosinophil chemokine (eotaxin) and hepatic glutathione levels. Furthermore, analysis of the gut microbiota and metabolome showed that LcS reduced the acetaminophen-enriched levels of Cyanobacteria, Oxyphotobacteria, long-chain fatty acids, cholesterol and sugars in the gut. Additionally, the transcriptome and proteomics showed that LcS mitigated the downregulation of metabolism and immune pathways as well as glutathione formation during acetaminophen-induced acute liver injury. This is the first study showing that pretreatment with LcS alleviates acetaminophen-enriched acute liver injury, and it provides a reference for the application of LcS.

Project description:To characterize the genetic basis of hybrid male sterility in detail, we used a systems genetics approach, integrating mapping of gene expression traits with sterility phenotypes and QTL. We measured genome-wide testis expression in 305 male F2s from a cross between wild-derived inbred strains of M. musculus musculus and M. m. domesticus. We identified several thousand cis- and trans-acting QTL contributing to expression variation (eQTL). Many trans eQTL cluster into eleven ‘hotspots,’ seven of which co-localize with QTL for sterility phenotypes identified in the cross. The number and clustering of trans eQTL - but not cis eQTL - were substantially lower when mapping was restricted to a ‘fertile’ subset of mice, providing evidence that trans eQTL hotspots are related to sterility. Functional annotation of transcripts with eQTL provides insights into the biological processes disrupted by sterility loci and guides prioritization of candidate genes. Using a conditional mapping approach, we identified eQTL dependent on interactions between loci, revealing a complex system of epistasis. Our results illuminate established patterns, including the role of the X chromosome in hybrid sterility.

Project description:The aim of the study was to investigate whether the trefoil peptide genes, in concerted action with a miRNA regulatory network, were contributing to nutritional maintrenance. Using a Tff2 knock-out mouse model, 48 specific miRNAs were noted to be significantly deregulated when compared to the wild type strain.
