Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Myocilin, a causative gene for open-angle glaucoma, encodes a secreted glycoprotein of unknown function. To elucidate its function(s), we produced a stably transfected HEK293 cell line expressing myocilin and compared the expression profiles between the myocilin-expressing cell line and a vector control cell line using Affymetrix GeneChip U133 plus 2.0 array. A significant portion of differentially-expressed genes in the myocilin-expressing cells was associated with cell growth and cell death, suggesting that myocilin may have an important role regulating cell growth/survival..

Description
In the current study, we have focused on a distinct group of non-coding elements, lncRNA, and profiled renal tissues from three different inbred rat strains. We chose the three strains S, SHR and R for the main purpose of cataloging lncRNA annotations from the most widely used rat models of cardiovascular and renal disease. Overall design: Identification of lncRNAs on the rat genome by next generation RNA sequencing (NGS)

Description
To clarify the effect of SHP in LXRs-mediated signaling pathway, we performed global gene expression analysis of SHP siRNA transfected- or control siRNA transfected- astrocytes after IFN- and LXRs agonist. Microarray analysis revealed that expression of several genes encoding inflammatory mediators were reversed in SHP siRNA transfected-astrocytes, when compared with control siRNA transfected-astrocytes.

Description
Organisms respond to mitochondrial stress through the upregulation of an array of protective genes, often perpetuating an early response to metabolic dysfunction across a lifetime. We find that mitochondrial stress causes widespread changes in chromatin structure through histone H3K9 di-methylation marks traditionally associated with gene silencing. Mitochondrial stress response activation requires the di-methylation of histone H3K9 through the activity of the histone methyltransferase met-2 and the nuclear co-factor lin-65. While globally the chromatin becomes silenced by these marks, remaining portions of the chromatin open up, at which point the binding of canonical stress responsive factors such as DVE-1 occurs. Thus, a metabolic stress response is established and propagated into adulthood of animals through specific epigenetic modifications that allow for selective gene expression and lifespan extension. Overall design: comparison of gene expression changes in response to cco-1 RNAi treatment in N2, lin-65(n3441) and met-2(ok2307) populations of C. elegans L4 animals

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Despite inheritance of hypertension in families, identifying genetic mechanisms predisposing individuals to hypertension has remained challenging. The effects of single genes contributing to the development of hypertension may not be readily detected in individuals whose genomes also contain other genetic factors that resist hypertension. By using a highly permissive rat genome for inherited hypertension, we demonstrate that increased expression of one such gene, Rififylin (Rffl), is a novel inherited risk factor for hypertension and increased mortality. Animals overexpressing Rffl demonstrated delayed endocytic recycling, accumulated polyubiquitinated proteins, increased beats/min of neonatal cardiomyocytes, had shorter QT-intervals and developed salt-insensitive hypertension very early in their life (50-52 days). Thus, the discovery of a physiological link between overexpression of rififylin and the development of hypertension constitutes a novel mechanism that could be targeted for rectifying normal QT-interval and preventing hypertension.

Augmented rififylin is a risk factor linked to aberrant cardiomyocyte function, short-QT interval and hypertension.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Evidence from multiple linkage and genome-wide association studies suggest that human chromosome 2 (HSA2) contains alleles that influence blood pressure (BP). Homologous to a large segment of HSA2 is rat chromosome 9 (RNO9), to which a BP quantitative trait locus (QTL) was previously mapped. The objective of the current study was to further resolve this BP QTL. Eleven congenic strains with introgressed segments spanning <81.8kb to <1.33Mb were developed by introgressing genomic segments of RNO9 from the Dahl salt-resistant (R) rat onto the genome of the Dahl salt-sensitive (S) rat and tested for BP. The congenic strain with the shortest introgressed segment spanning <81.8kb significantly lowered BP of the hypertensive S rat by 25 mm Hg and significantly increased its mean survival by 45 days. In contrast, two other congenic strains had increased BP compared with the S. We focused on the <81.8kb congenic strain which represents the shortest genomic segment to which a BP QTL has been definitively mapped to date in any species. Sequencing of this entire region in both S and R rats detected 563 variants. The region did not contain any known or predicted rat protein coding genes. Further, a whole genome renal transcriptome analysis between S and the <81.8kb S.R congenic strain revealed alterations in several critical genes implicated in renal homeostasis. Taken together, our results provide the basis for future studies to examine the relationship between the candidate variants within the QTL region and the renal differentially expressed genes as potential causal mechanisms for BP regulation.
