Ontology highlight
ABSTRACT: The goal of this study was to compare gene expression profiles between whole blood and PBMCs using the NanoString nCounter panCancer Immune Profiling Panel (730 endogenous genes)
Project description:The results (significance versus foldchange) showed 183 up- and 195 downregulated miR in the oxygen-glucose deprivation-PBMCs compared to normoxic PBMCs
Project description:RNA from tumor samples from 65 patients with melanoma, lung cancer, head and neck treated anti-PD1was analyzed on the nCounter system using the PanCancer 730-Immune Panel.
Project description:To determine miRNA transcribed during the PBMCs, we have employed whole genome microarray expression profiling as a discovery platform to identify miRNA expression in PBMCs donated by T1DM (type 1 diabetes mellitus) patients and healthy volunteers.
Project description:This study used the NanoString nCounter hybridization system and nCounter miRNA expression assays to identify and quantitate circulating cellular miRNAs during HIV-1 elite suppression, active HIV-1 replication, and uninfected status.
Project description:Peste des Petits Ruminants (PPR) is a highly infectious disease caused by a virus of the genus Morbillivirus (PPRV), infecting mainly sheep and goat. Susceptibility of host can vary widely with host breed and virus strain. The mechanisms underlying this variability are not well understood. Here, we carried out the first comparative in vitro study on goat peripheral blood mononuclear cells (PBMCs) infected with PPRV strains of different virulence, vaccine strain (N75/1), low- (IC89), and high-virulent strain (MA08). Goat PBMCs were infected by the different strains and stimulated with Concanavalin A (Con A), and proteome changes of these cells were evaluated during the infection. The level of PPRV replication was assessed first by RT-qPCR quantification of viral N mRNA and by labelling the viral N protein inside the cells with specific antibodies and analysed by flow cytometry. The dynamics of PBMC sub-populations were also evaluated by flow cytometry. Our results showed that viral replication is critical for PPRV inhibitory effect on PBMCs proliferation. Highly virulent MA08 strain reached a higher level of replication in ConA-stimulated PBMCs and induced higher mortality compared to other strains. Low-virulent IC89 strain showed the lower replication level and cell proliferative inhibitory capacities. Differences in immune genes expression levels were assessed using RNAseq analysis and protein expression was compared using mass spectrometry. Analysis of these data provided the transcriptional and proteome landscape of PBMCs infected with these strains. The possible association between the transcriptional and proteome landscape and changes in immune cell subpopulations dynamics was explored.
Project description:The effect of cafeteria (CAF) diet in PBMC gene expression was analyzed in two inbred rat strains the Wistar Kyoto(WKY) and Lewis (LEW) rat PBMCs were isolated following a CAF or standard diet and subjected to whole genome expression analysis
Project description:This study used the NanoString nCounter hybridization system and nCounter miRNA expression assays to identify and quantitate circulating cellular miRNAs during HIV-1 elite suppression, active HIV-1 replication, and uninfected status. Blood samples were from eight uninfected controls, seven HIV-1 elite suppressors with undetectable viral load, and six viremic HIV-1-infected patients.
Project description:Gene expression of HGSC according to chemotherapeutic response was analyzed using Nanostring nCounter PanCancer Immune Profiling Panel.
