Project description:The aim of this study was to investigate the antihypertensive effect of enzymatic hydrolysis of blue mussel protein (HBMP) in rats. Spontaneously hypertensive rats (SHRs) were orally administration with high- or low-dose of HBMP for 28 days. Major components of the renin-angiotensin (RAS) system in serum of SHRs from different groups were analyzed, and gene expression profiling were performed in the kidney of SHRs, using the Whole Rat Genome Oligonucleotide Microarray. Results indicated although genes involved in RAS system were not significantly altered, those related to blood coagulation system, cytokine and growth factor, and fatty acids metabolism were remarkablely changed. Several genes which were seldom reported to be implicated in pathogenesis of hypertension also showed significant expression alterations after oral administration of HBMP. SHRs were randomly divided into three groups (n=10): control group (rats were orally administered with water, 3mL), low-dose group (rats were orally administered with HBMP, 10 mg/kg/day, 3mL), and high-dose group (rats were orally administered with HBMP, 20 mg/kg/day, 3mL). After orally administered with HBMP for 4 weeks, all rats were killed and the kidneys were dissected. For each group, equivalent amounts of RNA from four individual rats were mixed, and transcribed to Cy3-labeled cRNA using the Agilent Low Input Quick Amp Labeling Kit (Agilent Technologies, Santa Clara, CA, USA). Then, Cy3-labeled cRNA from each group was hybridized to the Whole Rat Genome Oligonucleotide Microarray ver. 3.0 (4X44k, G2519F-028282) (Agilent Technologies), following the manufacturer's hybridization protocol.

Project description:Rosiglitazone, a peroxisome proliferator-activated receptor g (PPARg) agonist of the thiazolidinedione class, is a major insulin-sensitizing drug widely used to treat type-2 diabetes. Rosiglitazone causes myocardial hypertrophy in rodents and increases the risk of cardiac events in man. To better characterize its cardiac effects, male Wistar rats were orally administered 0, 10 or 80 mg/kg/day rosiglitazone. Male Wistar rats were orally administered 0, 10 or 80 mg/kg/day rosiglitazone once per day for 14 days. Samples were obtained 6, 24, 168 or 336 hours after the final treatment.

Project description:Fecal samples collected on day 5 from randomly selected colitic SD rats were analyzed for gut microbiota by sequencing the V4 region of the 16S rRNA gene. The orally administered Dex-P-laden NPA2 coacervate (Dex-P/NPA2) significantly restores the diversity of gut microbiota compared with colitic SD rats in the Dex-P/PBS group and the untreated colitic rats (Control).

Project description:We used spontaneously hypertensive rats (SHRs) as an animal model of hypertensive heart disease and treated them with allisartan orally. We continuously monitored the rats' blood pressure levels, measured their body and heart weights, and evaluated their cardiac structure and function using echocardiography. We performed proteome analysis using the tandem mass tag (TMT) technology.

Project description:Lactoperoxidase (LPO) is a component of milk and other external secretions. Recently, we found antiinflammatory effect of orally administered LPO in mouse model of influenza virus-induced pneumonia. In order to study influence of bovine LPO on the digestive tract as its possible target organ, we performed comprehensive gene expression analysis of the mouse small intestine using GeneChip microarray to compare the effect of LPO with that of water or bovine serum albumin (BSA). We observed that 3 h after single ingestion of LPO the levels of 78 gene expression are upregulated and those of 9 gene expressions are downregulated. Within most changed genes, 5 upregulated and 1 downregulated genes such as FK506 binding protein 5 (FKBP5) and serum/glucocorticoid regulated kinase (SGK) are known to be transcriptionally modulated by glucocorticoid. This result suggests that ingested LPO modulates gene expressions in the small intestine in a glucocorticoid-like manner and this activity may link to its systemic antiinflammatory effects. Experiment Overall Design: Mice were orally administered 200 microL of water (n=3), bovine serum albumin (BSA, 2.5 g/kg body weight, n=3), or bovine lactoperoxidase (LPO, 2.5 g/kg body weight, n=3). Three hours after administration, comprehensive gene expressions of jejunum detached payer's patch were analysed for comparison of LPO administration with water or BSA administration.

Project description:Spleens were collected from C57BL/6 mice that were treated with (1) saline, (2) a single dose of nanoparticles, (3) 3 doses of nanoparticles administered daily, or (4) 3 doses of nanoparticles administered every 3 days. Single-cell RNA-sequencing was conducted using the 10X Genomics platform and analyzed with Seurat.
