Identification of differentially expressed transcripts and pathways one week and six months following implant of left ventricular devices

ABSTRACT: A specific set of genes involved in regulating cellular immune response, antigen presentation, and T cell activation and survival were down-regulated 7 days after LVAD placement. 6 months following LVAD placement, the expression levels of these genes were significantly increased; yet importantly, remained significantly lower than age and sex-matched samples from healthy controls. Examination of the effect of LVAD implant on peripheral blood transcriptome. Blood was drawn before LVAD placement, 7 days post implant, and 180 days post implant. RNA sequencing was performaed on all samples.

<h4>Introduction</h4>Continuous-flow left ventricular assist devices (LVADs) are an established therapy for patients with end-stage heart failure. The short- and long-term impact of these devices on peripheral blood gene expression has not been characterized, and may provide insight into the molecular pathways mediated in response to left ventricular remodeling and an improvement in overall systemic circulation. We performed RNA sequencing to identify genes and pathways influenced by these devic ...[more]

Comparison of Gene Expression between Peri-implant Soft Tissue and Oral Mucosal Tissue

Comparison of the gene expression of periimplantitis affected peri-implant tissue and healthy peri-implant tissue in vivo in human.

Project description:In this study we want to ascertain the differences and similarities of infected and inflammated peri implant tissue versus healthy peri implant tissue at the mRNA level. Six of the patients where affected by periimplantitis. In situ dental implants where explanted because of inflammation and non-integration. From two patients, implants were explanted because of wrong placement. They where classified as implants with healthy periimplant tissue.

Characteristic regulation of Lbp and Sod3 gene expression in peri-implant connective tissue of rats

Comparison of Gene Expression between Peri-implant Soft Tissue and Oral Mucosal Tissue

Project description:The mucosal penetration area formed by implant placement is critical problems of dental implant treatment, because epithelial barrier is broken and it can become a source of inflammation. To clarify the influence and risk caused by dental implant treatment in peri-implant soft tissue, we compared to gene expression profile of peri-implant soft tissue and oral mucosal tissue with microarray analysis. Both side upper first molars of 4 week-old rat were extracted, and titanium alloy implants were placed only in the left extraction socket. Four weeks after surgery, samples were harvested from left side of peri-implant soft tissue and right side of oral mucosal tissue.

Genome wide array analysis of endosseous implant adherent cellular phenotypes

Project description:Objective: to identify the early molecular processes involved in osseointegration associated with a micro roughened and nanosurface featured implants. Thirty-two titanium implants with surface topographies exhibiting nanoscale features (AT-I) and microrough surface without nanoscale features (AT-II) were placed in the tibiae of 8 rats and subsequently harvested at 2 and 4 days after placement. Total RNA was isolated from cells adherent to retrieved implants. A whole genome microarray using the Affymetrix Rat gene 1.1 ST Array was used to describe the gene expression profiles that were differentially regulated by the implant surfaces.

Transcriptomic profile of Lin negative, LEPR positive cells of human peri-implant fibrous tissue and peri-implant bone

Project description:Peri-implant fibrosis is one of the most common reasons for implant failure and surgical revision after prosthetic joint replacement. This type of surgical revisionis associated with substantial additional morbidity and healthcare costs. However, the cellular and molecular mediators of peri-implant fibrosis remain unclear. Here, we show that peri-implant fibrotic tissue in mice and humans is largely composed of a specific population of leptin receptor-expressing(LEPR+) cells and that these LEPR+cells are necessary and sufficient to both generate and maintain peri-implant fibrotic tissue. Genetic ablation of LEPR+cells prevents peri-implant fibrosis, and implantation of LEPR+cells from peri-implant fibrotic tissue is sufficient to induce fibrosis in secondary hosts. We further identify adhesion G protein-coupled receptorF5 (ADGRF5) as a crucial mediator of the fibrotic response by LEPR+cells, as conditional deletion of ADGRF5 in LEPR+cells attenuates peri-implant fibrosis while augmenting peri-implant bone formation. Finally, we demonstrate that inhibition of ADGRF5 by intra articular or systemic administration of neutralizing anti-ADGRF5prevents and reverses peri-implant fibrosis. Thus, pharmaceutical agents that inhibit the ADGRF5 pathway inLEPR+cells may represent a new approach to prevent and treat peri-implant fibrosis.

RNA-seq of human patient-derived xenograft pancreatic cancer Panc185 sphere-derived cells with the ISG15 gene edited using CRISPR-CAS9 against control spheres.

Project description:The goal of the study was to identify genes and pathways that were altered in the absence of the gene Interferon-Stimulated Gene 16 (ISG15) in human pancreatic ductal adenocarcinoma (PDAC) cancer stem cells. Primary adherent cultures established from patient-derived xenograft passaged in mice were established (Panc185). The ISG15 gene was edited using CRISPR-CAS9 technology and 3 commercially available guide RNAs introduced via lentiviral infection. Control cultures were also established using control guide RNAs. Once a polyclonal population was established and ISG15 loss confirmed, cultures were grown as 3D spheres in ultralow attachment plates to achieve a CSC-enriched culture. Following 5 days in culture as spheres, Total RNA was isolated by the guanidine thiocyanate (GTC) method using standard protocols. PolyA+ RNA fraction was processed as in Illumina’s ‘‘TruSeq RNA Sample Preparation v2 Protocol’’. The resulting purified cDNA library was applied to an Illumina flow cell for cluster generation (TruSeq cluster generation kit v5) and sequenced on the Genome Analyzer IIx with SBS TruSeq v5 reagents by following manufacturer’s protocols. RNA-seq data sets were analyzed using the tool Nextpresso.
