Gene expression profiling of cultured cells from brainstem of spontaneously hypertensive and Wistar Kyoto rats

Project description:Hypertension is a multifactor disease that possibly involves alterations in gene expression in hypertensive relative to normotensive subjects that are largely unknown. In this study we used high-density oligoarrays to compare gene expression profiles in cultured neurons and glia from pons and medulla oblongata of newborn spontaneously hypertensive (SHR) and normotensive Wistar Kyoto (WKY) rats, a widely documented animal model of hypertension. We found 358 genes differentially expressed between SHR and WKY brainstem cells that preferentially map to 24 metabolic/signaling pathways. Some of the pathways and regulated genes identified herein are obviously related to blood pressure regulation; however there are several genes differentially expressed in SHR not yet associated to hypertension or participating in blood pressure regulation. These constitute a rich resource for the identification and characterization of novel genes involved in hypertension development, or associated to phenotypical differences observed in SHR relative to WKI. In conclusion, this study describes for the first time the gene profiling pattern of brainstem cells from SHR and WKY rats, which opens up new possibilities and strategies of investigation and possible therapeutics to hypertension, as well as for the understanding of the brain contribution in this pathology.

Transcription profiling of rat adrenal glands from spontaneously hypertensive (SHR) and normotensive Wistar-Kyoto animals

Project description:We measured gene expression in the adrenal glands of the Spontaneously Hypertensive Rat (SHR) and Wistar-Kyoto rat (WKY) using Affymetrix RG-U34A GeneChips. All rats were aged-matched at 4-weeks. The rats were obtained from the colonies at the Univeristy of California San Diego, La Jolla, CA.

Transcription profiling of rat left ventricular samples from 12-, 16- and 20-month old spontaneously hypertensive rats (SHRs) compared with age-matched Wistar-Kyoto (WKY) rats as controls

Project description:Left ventricular gene expression profiles from 12-, 16- and 20-months old spontaneously hypertensive rats (SHRs) were compared with left ventricular profiles seen in age-matched Wistar-Kyoto (WKY) rats [control rats] by screening Affymetrix U34A arrays (there are 4 samples in each timepoint except 3 samples of 20-months old WKYs).

Whole genome analysis of nicotine-exposed cells from the brainstem of spontaneously hypertensive and Wistar Kyoto rats

Project description:The development of hypertension may be highly influenced by the use of nicotine especially in genetically susceptible subjects. In this study the effects of nicotine on gene expression of cultured cells from the brainstem of spontaneously hypertensive (SHR) and Wistar Kyoto (WKY) rats were evaluated using whole genome microarray platforms. It was described for the first time that nicotine may act differentially on the gene expression profile of SHR and WKY. The influence of strain was present in 348 genes that were differentially expressed in SHR as compared to WKY brainstem cells independently of the nicotine treatment. 176 genes had their expression altered in both strains after nicotine exposure. Interaction between nicotine treatment and the strain was observed for the expression of 269 genes which participate of cellular pathways related to neurotrabnsmitter secretion, intracellular trafficking and cell communication. In conclusion, this study leaves a list of genes whose expression shall be better studied since they are good candidates to the phenotypic differentiation between SHR and WKY, including hypertension as well as demonstrated that alterations in the systems of intracellular trafficking and neurotransmission may be relevant to the development of hypertension.

Altered neurotrophin expression profiles in the nucleus of the solitary tract of spontaneously hypertensive rats

Project description:Our previous findings suggest that the nucleus of the solitary tract (NTS), a pivotal region for regulating the set-point of arterial pressure, exhibits abnormal inflammation in pre-hypertensive and spontaneously hypertensive rats (SHRs) together with elevated anti-apoptotic and low apoptotic factor levels compared with that of normotensive Wistar–Kyoto (WKY) rats. Whether this chronic condition affects neuronal growth and plasticity in the NTS remains unknown. To unveil the characteristics of the neurodevelopmental environment in the NTS of hypertensive rats, we investigated the gene expression profile of neurotrophins and their receptors in SHRs compared to that of normotensive rat WKY.

Gene expression profiles in the liver of spontaneously hypertensive rats at different stages of hypertension

Project description:The objective of this study was to characterize differences in the global gene expression profiles of spontaneously hypertensive rats (SHR) and Wistar Kyoto rats (WKY) at different stages of hypertension. Using RNA isolated from liver of SHR and WKY rats, we compared the gene expression profiles by microarrays. Differential gene expression was detected in the liver of SHR rats compared to WKY control rats, possibly contributing to hypertension
