Project description:The polygenic nature of essential hypertension and its dependence on environmental factors pose a challenge for biomedical research. We hypothesized that microarray analysis of differential gene expression in peripheral blood cells would distinguish patients with hypertension from normotensive controls. We utilized microaaray analysis of differential gene expression in peripheral blood cells to identify differences in transcription profile of human essential hypertension compared with normotensive volunteers.

We utilized microaaray analysis of differential gene expression in peripheral blood cells to identify differences in transcription profile of human essential hypertension compared with normotensive volunteers. Samples were pooled from participants who met with our recruitment criteria for RNA extraction and hybridization on Affymetrix Gene Chips Human Genome U133 Plus 2.0 Array. Experiments were performed at CapitalBio Corporation (Beijing, China)

Project description:Rationale: Pulmonary arterial hypertension is a common and potentially fatal complication of scleroderma that may involve inflammatory and autoimmune mechanisms. Alterations in the gene expression of peripheral blood mononuclear cells have been previously described in patients with pulmonary arterial hypertension. The ability to identify patients at risk for developing pulmonary hypertension would be clinically beneficial. Objective: To identify genes that are differentially expressed in peripheral blood mononuclear cells in scleroderma patients with and without pulmonary hypertension which could be used as biomarkers of disease for early diagnosis and provide insight into pathogenesis of pulmonary hypertension in at-risk populations. Methods and Results: Gene expression analysis was performed on a carefully characterized Microarray Cohort of scleroderma patients with (n=10) and without (n=10) pulmonary hypertension. Differentially expressed genes were confirmed in the Microarray Cohort and validated in a separate Validation Cohort of scleroderma patients with (n=15) and without (n=19) pulmonary hypertension by RT-qPCR. We identified inflammatory and immune-related genes including interleukin-7 receptor (IL-7R) and chemokine receptor 7 (CCR7) as differentially expressed in patients with scleroderma-associated pulmonary hypertension. Flow cytometry confirmed decreased expression of IL-7R on circulating CD4+ T cells from scleroderma patients with pulmonary hypertension. Conclusions: Differences exist in the expression of inflammatory and immune-related genes in peripheral blood cells derived from patients with scleroderma-related pulmonary hypertension compared to those with normal pulmonary artery pressures. These findings may have implications as biomarkers to screen at-risk populations to facilitate early diagnosis and provide insight into inflammatory and autoimmune mechanisms of scleroderma-related pulmonary hypertension. Gene expression analysis was performed on a carefully characterized Microarray Cohort of scleroderma patients with (n=10) and without (n=10) pulmonary hypertension. Differentially expressed genes were confirmed in the Microarray Cohort by RT-qPCR.

Project description:Long non-coding RNAs (LncRNAs) in hypertensives and their mechanisms in regulating blood pressure still remain unexplored. The aim of present study is to construct the profiles of LncRNAs in blood of patients with essential hypertension and healthy controls. Methods and results, LncRNA microarray identified up-regulated, anddown-regulated LncRNAs, in hypertensives compared to their healthy controls. Among them, one vascular smooth muscle (VSM)-specific LncRNA AK096656 (LncVSM) was quantitated in plasma of patients with hypertension and their healthy controls using the real-time qRT-PCR. LncVSM shows specific expression in human arterial vascular smooth muscle cells (HASMCs) and promote its proliferation and migration. Expression profiles and Ingenuity Pathway Analysis (IPA) revealed that LncVSM activated Renin-Angiotensin Signaling (RAS). the overexpression of LncVSM would result hypertension related complications.

Project description:In the present study through microarray analysis we looked into the mRNA differential expression in peripheral blood of PCOS patients v/s control women. The results implicated that many signalling networks as MAPK pathway, Androgen signaling, Insulin signaling and Immune signaling are regulated in peripheral blood of PCOS patients. The data indicate that there is generic PCOS specific gene expression in peripheral blood of PCOS subjects which can reflect the same from other PCO tissues. Total RNA was extracted from peripheral blood of 4 PCOS patients and 4 control subjects and compared for mRNA diferential expression through microarray.
