Project description:Unilateral femoral artery occlusion (right side) and a sham operation on the contralateral (left) side was performed in C57BL/6J mice under anesthesia by double ligation of the superficial femoral artery proximal to the deep femoral artery and distal femoral artery. Animal numbers are stated with the different experimental results. Total RNA was isolated from the distal adductor muscles by phenol-chloroform isolation (TRIzol, Invitrogen, Carlsbad, CA) at baseline and at 5 time points after femoral artery ligation (6h, 24h, 3 days, 7 days, 14 days) from 5 mice per time point. RNA was pooled in equal amounts, and microarray analysis for all identified murine miRNAs (miRBase 9.0) was performed by a service provider (LC Sciences, Houston, TX).

Project description:To determine the differential expression of genes at sites of vascular injury in mice Four male, 5-6 mo old SMA-GFP mice (numbered 57, 60, 61, and 63) were subjected to fine wire femoral artery injury. The left femoral artery of each mouse was injured, and the contralateral artery was used as an uninjured control. The mice recovered from the injury procedure for 14 days, at which time they were sacrificed. The femoral arteries were removed and the adventitial side was extensively cleaned. The arteries were carefully opened longitudinally and immediately imaged for GFP. GFP-negative regions of the arteries, representing sites of vascular injury were microdissected, quick-frozen on dry ice, and stored in liquid nitrogen. Uninjured arteries were isolated and analyzed similarly; the entire uninjured artery was frozen. Total RNA was prepared. A 100-ng portion of each sample was subjected to linear amplification and hybridized to Affymetrix mouse gene 1.0ST.

Project description:This is an investigation of whole genome gene expression level in tissues of mice stimulated by LPS, FK565 or LPS + FK565 in vivo and ex vivo. We show that parenteral administration of a pure synthetic Nod1 ligand, FK565, induces site-specific vascular inflammation in mice, which is prominent in aortic root including aortic valves, slight in aorta and absent in other arteries. The degree of respective vascular inflammation is associated with persistent high expression of proinflammatory chemokine/cytokine genes in each tissue in vivo by microarray analysis, and not with Nod1 expression levels. The ex vivo production of proinflammatory chemokine/cytokine by Nod1 ligand is higher in aortic root than in other arteries from normal murine vascular tissues, and also higher in human coronary artery endothelial cells (HCAEC) than in human pulmonary artery endothelial cells (HPAEC), suggesting that site-specific vascular inflammation is at least in part ascribed to an intrinsic nature of the vascular tissue/cell itself.

A fourty chip study using total RNA recovered from four isolated tissues of mice which were stimulated by various reagents. Aortic root, pulmonary artery, aorta and spleen of mice in 3 groups: 1) intraperitoneal injection of 20M-NM-<g of LPS priming only, 2) oral administration of FK565 (100M-NM-<g) for consecutive days, 3) oral administration of FK565 (100M-NM-<g) for consecutive days 1 day after LPS priming, at day 2, 4, and 7. And six chip study using total RNA recovered from three isolated vascular tissues of mice which were stimulated by FK565 (10M-NM-<g/mL) ex vivo.

Project description:Introgressed variants from other species can be an important source of genetic variation because they may arise rapidly, can include multiple mutations on a single haplotype, and have often been pretested by selection in the species of origin. Although introgressed alleles are generally deleterious, several studies have reported introgression as the source of adaptive alleles-including the rodenticide-resistant variant of Vkorc1 that introgressed from Mus spretus into European populations of Mus musculus domesticus. Here, we conducted bidirectional genome scans to characterize introgressed regions into one wild population of M. spretus from Spain and three wild populations of M. m. domesticus from France, Germany, and Iran. Despite the fact that these species show considerable intrinsic postzygotic reproductive isolation, introgression was observed in all individuals, including in the M. musculus reference genome (GRCm38). Mus spretus individuals had a greater proportion of introgression compared with M. m. domesticus, and within M. m. domesticus, the proportion of introgression decreased with geographic distance from the area of sympatry. Introgression was observed on all autosomes for both species, but not on the X-chromosome in M. m. domesticus, consistent with known X-linked hybrid sterility and inviability genes that have been mapped to the M. spretus X-chromosome. Tract lengths were generally short with a few outliers of up to 2.7 Mb. Interestingly, the longest introgressed tracts were in olfactory receptor regions, and introgressed tracts were significantly enriched for olfactory receptor genes in both species, suggesting that introgression may be a source of functional novelty even between species with high barriers to gene flow.

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:We performed wire-induced injuries in 12 week old C57BL/6J mice. Dilation of the femoral artery was performed by inserting a straight spring wire (0.38 mm diameter) for 10 mm towards the iliac artery, as described previously (Sedding D, Daniel JM, Muhl L, Hersemeyer K, Brunsch H, Kemkes-Matthes B, Braun-Dullaeus RC, Tillmanns H, Weimer T, Preissner KT, Kanse SM. The g534e polymorphism of the gene encoding the factor vii-activating protease is associated with cardiovascular risk due to increased neointima formation. The Journal of experimental medicine. 2006;203:2801-2807). Mice were sacrificed and perfused with phosphate buffered saline via the left ventricle. Femoral arteries were excised at 10 and 21 days after injury, snap-frozen and miRNA was isolated by phenol-chloroform extraction following the purelink
