TranscriptomicsMolecular Characterization of Laser Microdissected Circumventricular Organs and Third Ventricle Ependyma in the Adult Rat by Microarray Analysis.
We used LCM and microarrays to analyze the transcriptomes of three CVOs, the SCO, the subfornical organ (SFO), and the PG, and the third ventricle ependyma in the adult rat in order to better characterize these organs at the molecular level. Gene expression was performed on laser microdissection of...

TranscriptomicsTranscription profiling of feft ventricle in three genetic rat models of hypertension
Left ventricle gene expression was analyzed in three models of hypertension in order to clarify the molecular mechanisms associated with left ventricular hypertrophy. Transgenic heterozygous TGR(mRen2)27 rats, overexpressing the mouse renin gene, and their littermate negative controls, spontaneously...

TranscriptomicsTranscription profiling of models of cardiac remodelling: myocardial infarction or transverse aortic constriction in left ventricle free wall and septum
We employed the Affymetrix GeneChip technology to evaluate the patterns of expression in two different in vivo models of cardiac remodeling and in two different regions (left ventricle free wall and septum) of the heart. Mice underwent transverse aortic constriction (TAC); myocardial infarction (MI)...

TranscriptomicsEffects of vitamin A on ventricular myocardium gene expression [left ventricle]
LRAT knockout mice on vitamin A sufficient or deficient diets were compared to age and gender matched wildtype mice on a vitamin A sufficient diet RNA was isolated from the left ventricle of the heart and one array was run for each sample.

TranscriptomicsEffects of vitamin A on Ventricular myocardium gene expression [right ventricle]
LRAT knockout mice on vitamin A sufficient or deficient diets were compared to age-matched wild type mice on a vitamin A sufficient diet RNA was isolated from right ventricle of the heart and one array was run for each sample.

TranscriptomicsDistinctive Profile of IsomiR Expression and Novel MicroRNAs in Rat Heart Left Ventricle
MicroRNAs (miRNAs) are single-stranded non-coding RNAs that negatively regulate target gene expression through mRNA cleavage or translational repression. There is mounting evidence that they play critical roles in heart disease. The expression of known miRNAs in the heart has been studied at length ...

TranscriptomicsThymidine Kinase and mtDNA Depletion in Human Cardiomyopathy: Epigentic and Translational Evidence for Energy Starvation
A comparison of epigenetic nuclear DNA methylation and gene expression changes between human dialated cardiomypathy left ventricle samples and non-failing cardiac left ventricule samples This study addresses how depletion of huaman cardiac left ventricle mitochondrial DNA and epigentic nuclear DNA m...

TranscriptomicsCardiac phase-targeted dynamic load on left ventricle differentially regulates phase-sensitive gene expressions and pathway activation
Each heart was assigned to one of the following three conditions: phasic systolic overload (SO), phasic diastolic overload (DO), and no loading throughout the cardiac cycle (control; CN). We created SO by isovolumic contraction (peak systolic LVP > 170 mmHg) at a constant diastolic volume with end-d...

TranscriptomicsCardiac biopsies reveal differences in transcriptomics between left and right ventricle in patients with or without diagnostic signs of heart failure
Heart failure (HF) impacts 2-3% of adults in the West, with prevalence rising with age. This condition, leading to high mortality and morbidity, increasingly involves HF with preserved left ventricular (LV) ejection fraction (HFpEF) in the aging population, having a similar stable prognosis as HF wi...
