Project description:The study examined the role of TNF alpha in regulation of liver regeneration. For this purpose animals were divided in three groups of healthy controls, 2/3 partial hepatectomy alone, and animals pretreated with TNF alpha antagonist followed by 2/3 partial hepatectomy. Liver regeneration responses were then examined in conjunction with gene expression analysis at the peak of partial hepatectomy induced DNA synthesis. Substantive differences were identified in multiple gene ontology groups and cellular events and processes to indicate that TNF alpha was deleterious for partial hepatectomy induced liver regeneration.
Project description:Maternal obesity during pregnancy leads to a pro-inflammatory milieu in the placenta. We conducted a global transcriptomic profiling in BeWo cells following palmitic acid (PA, 500 uM) and/or TNF-alpha (10 ng/ml) treatment for 24 h. Microarray analysis revealed that placental cytotrophoblasts increased expression of genes related to inflammation, stress response and immediate-early factors in response to plamitic acid, TNF-alpha or a combination of both. Our results suggest that fatty acids and inflammatory cytokines induce inflammation in placental cells via activation of JNK-Egr-1 signaling. global transcriptomic profiling in BeWo cells following palmitic acid (PA, 500 uM) and/or TNF-alpha (10 ng/ml) treatment for 24 h
Project description:We report cytokine specific changes in gene expression in the human neutrophil transcriptome using TNF-alpha and GM-CSF stimulation of healthy neutrophils Healthy human neutrophils were stimulated with TNF-alpha or GM-CSF for 1h in vitro. RNA was analysed by SOLiD and Illumina sequencing. RNA from one biological donor was sequenced on both platforms, and two different biological donors were sequenced by Illumina.
Project description:We report gene expression in human neutrophils isolated by two methods: Polymorphprep (~95% purity) and negative selection (~99% purity) from two healthy donors - one donor with low eosinophil contamination of neutrophils and one donor with high eosinophil contamination of neutrophils. We report the effect of the presence of contaminating leukocytes in neutrophil preparations, and in reponse to inflammatory cytokines TNF-alpha and GM-CSF. Healthy human neutrophils were isolated using Polymorphprep or negative selection, and incubated for 1h in the absence or presence of TNF-alpha or GM-CSF. RNA was analysed by Illumina HiSeq 2000. The results from n=2 donors were analysed as biological replicates for differential expression analysis.
Project description:Cardiac-specific TNF-alpha transgenic mice are an excellent model to study the pathologenesis of heart failure. Affymetrix U74V2A was used to analyze the gene expression profile of male and female wildtype FVB and TNF-alpha transgenic mice at the time point of compensated hypertrophy and dilated heart failure. 3 week, 13 week and 40 week samples examined.

Project description:To investigate the role of DREAM (a transcriptional repressor) in regulating gene transcription in neutrophils under inflammatory conditions, we conducted the next generation sequencing using unstimulated and TNF-alpha-stimulated neutrophils isolated from WT and DREAM KO mice.
