Whole blood gene expression profiling for coronary in-stent restenosis: A Indian pilot case study.

ABSTRACT: Percutaneous coronary intervention (PCI) with stent placement is a standard treatment for coronary artery disease (CAD). Despite all medical advances, restenosis remains a challenging clinical problem. However, the molecular and biochemical pathways of restenotic process are not fully understood yet. Furthermore, as restenosis is assumed to be a multigenetic process and genetic predisposition is considered an important risk factor, analysis of the genome-wide gene expression is recommended for better insight of the phenomenon. We used microarray technology to monitor thousands of genes expression simultaneously. The whole genome expression will be analyzed with this technique to identify cluster of up-regulated and down-regulated genes which may be involved in this complex pathological condition.

Molecular and biochemical pathways of restenotic process are not fully understood yet. Furthermore, as restenosis is assumed to be a multigenetic process. We used microarray technology to monitor thousands of genes expression simultaneously in restenosis postive group with reference restenosis negative group, which will unravel potentially modifiable pathways, possible targets and biomarkers for coronary restenosis.

Inflammation and Extracellular Matrix Genes Differentially Expressed Following Overlapping Zotarolimus- and Sirolimus-Eluting Stent Implantation

Project description:An unanticipated complication of the use of bare metal stents in percutaneous transluminal coronary angioplasty is in-stent restenosis resulting in >50% late lumen diameter loss in treated patients. In an effort to reduce in-stent restenosis, drug eluting stents containing the immunosuppressant sirolimus or zotarolimus have recently been developed. We report here the molecular response of arterial tissue to the implanting of these drug-eluting stents. Gene expression profiling was performed on 4 artery segments surrounding bare metal stents (BMS), 4 artery segments surrounding sirolimus-eluting stents (SES), and 4 artery segments surrounding zotarolimus-eluting stents (ZES) implanted into porcine animal models for 28 days.

Screening for differentially expressed circRNAs in ischemic stroke by RNA sequencing

Project description:Acute coronary syndrome (ACS) is one of the most serious cardiovascular diseases. Percutaneous coronary intervention (PCI) combined with stent implantation improves outcomes in patients with ACS. However, the treatment of in-stent restenosis in ACS patients remains a major clinical challenge. In this study, RNA library construction and high-throughput sequencing were performed. The DEmRNA-DElncRNA co-expression analysis showed that there were 19 DElncRNA-DEmRNA relationship pairs (including 15 DEmRNA, 3 DElncRNA) in the PCI_NR/PCI_Re and NC/PCI_Re intersection group and 993 DElncRNA-DEmRNA relationship pairs (including 74 DEmRNA, 19 DElncRNA) in the NC/ACS and ACS/PCI_NR intersection group. We selected genes in the top 10 of differential expression and those involved in the co-expression of lncRNA-mRNA for diagnostic analysis. The area under curve (AUC) of PDZK1IP1, PROK2 and LAMP3 were greater than 0.7, which were 0.747, 0.769 and 0.725, respectively. It is indicated that PDZK1IP1, PROK2 and LAMP3 may as the potential diagnostic gene biomarkers in ACS.

Gene expression profiling of 3T3 fibroblast cells cultured with degradable metallic materials

Project description:Metals have been used for coronary artery stent materials in order to prevent stenosis caused by atherosclerosis. Degradable metallic materials (DMMs) are considered to be useful to avoid in-stent restenosis and late thrombosis. A new DMM, Fe-35Mn alloy, was fabricated through powder metallurgy in order to satisfy the ideal criteria of cardiovascular stent made of DMM. Since in-stent restenosis is mediated by the extracellular matrix production, which is mostly regulated by fibroblasts, the gene expression profile of 3T3 fibroblasts in the presence of Fe-35Mn alloy was then investigated. The mechanism of cellular responses in the presence of DMM is then expected to be clearly described through the gene profiling experiment.

Novel biomarkers for contrast-induced acute kidney injury identified from RNA sequencing data

Project description:Contrast-induced acute kidney injury (CI-AKI) is a serious complication of percutaneous coronary intervention (PCI). Emerging evidence suggests that messengerRNAs (mRNAs) and long non-coding RNAs (lncRNAs) could serve as biomarkers for various diseases.
