Transcriptome analysis was performed to determine what gene expression changes occur in response to treatment of the plant-derived compound harmine and to determine its effect on protein kinase C agonist reactivation of latent HIV.
Harmine enhances the activity of the HIV-1 latency-reversing agents ingenol A and SAHA.

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 SamplesIdiopathic pulmonary fibrosis (IPF) is a refractory and lethal interstitial lung disease characterized by alveolar epithelial cells apoptosis, fibroblast proliferation and extra-cellular matrix proteins deposition. Epstein - Barr virus (EBV) has previously been localised to alveolar epithelial cells of IPF patients. In this study we utilised a microarray based differential gene expression analysis strategy to identify potential molecular drivers of EBV associated lung fibrosis. We employed an alveolar epithelial cell line infected with EBV (A-Akata). Lytic phase infection induced in the A-Akata cells by TPA/BA treatment resulted in increase of TGFbeta1 and TIEG1 mRNA expression. Treatment of the A-Akata cells with ganciclovir,

View SamplesThe multifunctional protein tyrosine phosphatase PRL-1 (Gene Symbol: PTP4A1) has been identified as an important oncogene with roles in promoting cell proliferation, survival, migration, invasion, and metastasis. However, little is currently known about the signaling pathways through which it mediates its effects.

View SamplesTranscriptional profiling of histone methyltransferase SUV39H1-selective small molecule inhibitor F5446-induced genes in human colon carcinoma cells. Tumor cells were treated with F5446 for 48h and used for RNA isolation. The treated cells were compared to untreated control cells. The objective is to identify genes that are regulated by H3K9me3 in the metastatic human colon carcinoma cells.

View SamplesMouse strains have been identified that are resistant (i.e. DBA/2) or susceptible (i.e. C57BL/6) to infection from pathogenic fungus Coccidioides immitis. However, the genetic and immunological basis for this difference has not been fully characterized.
Factors regulated by interferon gamma and hypoxia-inducible factor 1A contribute to responses that protect mice from Coccidioides immitis infection.
