Alteration of Gene Expression Profile in Spontaneously Hypertensive Rats Treated with Protein Hydrolysate of Blue Mussel (Mytilus edulis) by DNA Microarray Analysis

ABSTRACT: 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.

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.

Different Gene Expression Profile in Spontaneously Hypertensive Rats Treated with Songling Xuemaikang Capsule

Project description:To study in vivo action of Songling Xuemaikang Capsule (SXC), SHRs were orally administration with high- or low-dose of SXC for 28 days.Valsartan, an angiotensin receptor antagonist, is used as a positive control drug in this study and orally administrated for 28 days. The levels of AngII, Aldosterone in serum of SHRs from different groups were analyzed, and gene expression profiling were performed in the thoracic aortakidney of SHRs, using the Whole Rat Genome Oligonucleotide Microarray. The integrated causal network analysis is performed to understand the mechanism of antihypertensive effect of SXC. The results showed that expression of 706 unique genes (p<0.05) were changed (fold change >2.0) in SHRs at a dose of 472.5 mg/kg day SXC when compared with control rats, whereas the expression of 920 unique genes were changed (fold change>2.0) at a dose of 1417.5 mg/kg/day. Those genes are involved in lipid metabolism, complement system induced immune response, inflammation and vascular and endothelial dysfunction.

Transcriptomic response in the heart and kidney to different types of antihypertensive drug administration

Project description:To unravel antihypertensive drug-induced gene expression changes that are potentially related to the amelioration of end-organ damages, we performed in vivo phenotypic evaluation and transcriptomic analysis on the heart and the kidney, with administration of antihypertensive drugs to two inbred strains of (i.e., hypertensive and normotensive) rats. We chose to use six antihypertensive classes: enalapril (angiotensin converting enzyme inhibitor), candesartan (angiotensin receptor blocker), hydrochlorothiazide (diuretics), amlodipine (calcium-channel blocker), carvedilol (vasodilating -blocker) and hydralazine. In the tested rat strains, four of six drugs, including two renin-angiotensin system (RAS) inhibitors, were effective for BP lowering, whereas the remaining two drugs were not. Besides BP lowering, there appeared to be some inter-drug heterogeneity in phenotypic changes, such as suppressed body weight (Bw) gain and Bw-adjusted heart weight reduction. For the transcriptomic response, a considerable number of genes showed prominent mRNA expression changes either in a BP-dependent or BP-independent manner with substantial diversity between the target organs. Noticeable changes of mRNA expression were induced particularly by RAS blockade, e.g., for genes in the natriuretic peptide system (Nppb and Corin) in the heart and for those in the RAS/ kallikrein-kinin system (Ren and rat Klk1 paralogs) and those related to calcium ion binding (Calb1 and Slc8a1) in the kidney. The heart data comprises of this submission and part of E-MTAB-9244.

Mytilus edulis blue mussel larval development Control vs. Fatty acid diet deficiency

Project description:Blue mussel larvae were fed, in a first group, a balanced diet of essential fatty acids (EFAs) provided by a cocktail diet (COC) from three algal species. Larvae were cultured in three separate tanks from hatching, 0 day post-fertilization (DPF) until 42 DPF. Treated larvae were fed a deficient diet (Tiso) that contains low levels of arachidonic acid (AA) and eicosapentaenoic acid (EPA), two EFAs necessary for larval development, performance, and survival. The goal is to identify coordinated patterns of gene expression and understand their predictive function in relation to growth and mortality during early developmental stages of the blue mussel Mytilus edulis. In order to understand the mechanisms by which growth and survival drive an organism to the full range of its adaptation, we de novo assembled of the mussel transcriptome during early development using next-generation sequencing (NGS) technology, then designed customized microarrays targeting every developmental stage, which encompass major transitions in tissue organization of the fast-evolved blue mussel
