Little is known about the pan-microvascular transcriptome, particularly considering gene transcripts and their encoded proteins that can be considered as vascular-selective in their expression.
Identification of a core set of 58 gene transcripts with broad and specific expression in the microvasculature.

View SamplesVascular smooth muscle cells (VSMC) are important for contraction, blood flow distribution and regulation of blood vessel diameter, but to what extent they contribute to the integrity of blood vessels and blood-brain barrier function is less well understood. In this report, we explored the impact of the progressive loss of VSMC in the Notch3-/- mouse on blood vessel integrity in the central nervous system
Notch3 is necessary for blood vessel integrity in the central nervous system.

View SamplesEnteric glial cells (EGCs) are the main constituent of the enteric nervous system and share similarities with astrocytes from the central nervous system including their reactivity to an inflammator microenvironment. In this study we isolated GFAP-positive myenteric glia from FVB/hGFAP-eGFP transgenic postnatal day 7 mice. Following cell sorting for the eGFP reporter, GFAP-positive EGCs were cultured for 3 weeks to generate neurosphere-like bodies. This cell culture was stimulated with LPS for 48 h and cells were employed for gene expression profiling. LPS-stimulated cell cultures were compared to untreated control cell cultures. Enriched GFAP+ EGC cultures secreted increased levels of prominent inflammatory cytokines upon LPS stimulation. Further, in vitro cultures were compared to GFAP-eGFP-positive cells directly analyzed after cell sorting of small intestinal LMMP digests (in vivo) to assess alterations in transcriptomic profiles due to the in vitro culture.

View SamplesTo search for rapid changes in gene expression following BCR activation, we performed DNA microarray analysis of activated splenic B cells with and without anti-IgM treatment for 3 hour. The expression of a remarkably large set of genes differed significantly.

View SamplesPhloem-feeding pests cause extensive crop damage throughout the world yet little is understood about how plants perceive and defend themselves from these threats. The silverleaf whitefly (SLWF; Bemisia tabaci type B) is a good model for studying phloem-feeding insect-plant interactions as SLWF nymphs cause little wounding and have a long, continuous interaction with the plant. Using the Arabidopsis ATH1 GeneChip, the global responses to Silverleaf Whitefly 2nd instar feeding were examined.

View SamplesISCOM vaccines induce a balanced Th1/Th2 response and cytotoxic T lymphocytes. The adjuvant component, ISCOM-Matrix, consists of purified saponin fractions, cholesterol and phospholipids. The mode of action for the ISCOM-Matrix is known to some extent but still we lack knowledge of important segments in initiation of the immune response. The study was performed to analyze the early transcriptional responses to the ISCOM-Matrix alone, without the use of co-administered antigen. Matrix M (AbISCO 100) was given as intramuscular injection and after 24 hours the pigs was sacrificed for gene expression analysis, performed for the injection site and the draining lymph node.

View SamplesPurpose: The purpose of this study is to measure the changes in liver transcriptome in response to short-term fasting between 7 and 13 h where the rats were dosed with 2 ml/kg of saline vehicle at 0 h Methods: Total RNA was isolated from the liver, using TRIzol Reagent (Thermo Fisher Scientific, Waltham, MA) and the direct-zol RNA Mini Prep kit (Zymo Research, Irvine, CA). The isolated RNA samples were then submitted to the Vanderbilt University Medical Center VANTAGE Core (Nashville, TN) for RNA quality determination and sequencing. Total RNA quality was assessed using a 2100 Bioanalyzer (Agilent, Santa Clara, CA). At least 200 ng of DNase-treated total RNA with high RNA integrity was used to generate poly-A-enriched mRNA libraries, using KAPA Stranded mRNA sample kits with indexed adaptors (Roche, Indianapolis, IN). Library quality was assessed using the 2100 Bioanalyzer (Agilent), and libraries were quantitated using KAPA library Quantification kits (Roche). Pooled libraries were subjected to 75-bp paired-end sequencing according to the manufacturer's protocol (Illumina HiSeq3000, San Diego, CA). Results: No genes were were found to be differentially expressed with a false discovery rate less than 0.1 Conclusions: There were no significant changes in liver gene expression between 7 and 13 h of fasting Overall design: Liver mRNA profiles of 7- and 13-h fasted Sprague-Dawley rats were generated by RNA-seq.
