Patients with chronic illnesses such as Irritable Bowel Syndrome (IBS) or Inflammatory Bowel Disease (IBD) often have reduced quality of life. IBS is characterized by abdominal pain/discomfort associated with altered bowel function, such as diarrhea or constipation, without gross structural changes or inflammation [1]; IBD is characterized by gross inflammation in the gastrointestinal (GI) tract which can result in symptoms such as abdominal pain, cramping, diarrhea and bloody stools. IBS and IBD can profoundly affect quality of life and are influenced by stress and resiliency.The impact of mind-body interventions (MBIs) on IBS and IBD patients has not previously been examined. In this study IBS and IBD patients were enrolled in a 9-week relaxation response based mind-body group intervention (RR-MBI), focusing on elicitation of the RR and cognitive skill building. We performed Peripheral blood transcriptome analysis to identify genomic correlates of the RR-MBI.

View SamplesPrimary human foreskin fibroblasts (HFF) were exposed to either salt stress (80mM KCl) or heat stress (44ºC). Newly transcribed RNA was labelled by adding 500µM 4-thiouridine (4sU) to the cell culture media for 1h. Total cellular RNA was isolated using Trizol. Newly transcribed RNA was purified following the protocol described in Raedle et al. JoVE 2013. Overall design: Newly transcribed RNA was labelled in one hour intervals during either salt or heat stress (prior to stress, 0-1h or 1-2h). All 4sU-RNA samples were sent for sequencing. Two independent biological replicates were analysed.
HSV-1-induced disruption of transcription termination resembles a cellular stress response but selectively increases chromatin accessibility downstream of genes.

View SamplesQuiescent stem cells of glioblastoma (GBM), a malignant primary brain tumor, are potential sources for recurrence after therapy. However, the gene expression program underlying the physiology of GBM stem cells remains unclear. We have isolated quiescent GBM cells by engineering them with a knock-in H2B-GFP proliferation reporter and expanding them in a 3D tumor organoid model that mimics tumor heterogeneity. H2B-GFP label retaining quiescent cells were subjected to stem cell assays and RNA-Seq gene expression analysis. While quiescent GBM cells were similar in clonal culture assays to their proliferative counterparts, they displayed higher therapy resistance. Interestingly, quiescent GBM cells upregulated epithelial-mesenchymal transition (EMT) genes and genes of extracellular matrix components. Our findings connect quiescent GBM cells with an EMT-like shift, possibly explaining how GBM stem cells achieve high therapy resistance and invasiveness, and suggest new targets to abrogate GBM. Overall design: Glioblastoma cancer cells in 3D organoid culture were pulsed for 2 weeks with H2B-GFP, then chased either 2 or 4 weeks. Label-retaining GFP-high cells (quiescent) were separated from bulk population, and both populations were analyzed by RNA-Seq.
Gene signatures of quiescent glioblastoma cells reveal mesenchymal shift and interactions with niche microenvironment.

View SamplesPrimary human foreskin fibroblasts (HFF) were infected with wild-type simplex virus 1 (HSV-1) strain 17 at a multiplicity of infection (MOI) of 10. Newly transcribed RNA was labelled by adding 500µM 4-thiouridine (4sU) to the cell culture media for 1h. Total cellular RNA was isolated using Trizol. Newly transcribed RNA was purified following the protocol described in Raedle et al. JoVE 2013. Overall design: Newly transcribed RNA was labelled in one hour intervals during the first eight hours of HSV-1 infection. All nine 4sU-RNA samples as well as total cellular RNA of every second hour of infection were sent for sequencing. Two independent biological replicates were analysed.

View SamplesThe purpose of this experiment was to identify oestrogen regulated genes in human primary cell cultures of neuronal and glial cells modelling the developing human nervous system. We were especially interested in genes involved in proliferation, differentiation and migration of neuronal cells and genes involved in or linked to neurodegenerative diseases. We have therefore assessed gene expression changes, using Affymetrix GeneChips (HG-U133A), of oestrogen treated human neuronal/ glial cell cultures. We continued with 14 selected genes and confirmed the gene expression changes, by relative quantitative real time PCR, of 6 genes (p< 0.05) important in neuronal development, three of which also are suggested to have links to neurodegenerative diseases.

View SamplesGliomas arising in the brainstem and thalamus are devastating tumors that are difficult to surgically resect due to their proximity to eloquent brain structures. Here, we performed a comprehesive genomic and epigenomic study, using gene expression and methylation microarrays, to research on th different genomic and epigenetic signatures between brainstem, thalamic, and supratentorial gliomas.

View SamplesThe gene expression pattern of spherical neural masses (SNM) derived from HPRT knockdown murine D3 stem cells during neuronal differentiation to final neurons was invesitigated by RNA-Seq based gene expression analysis and the results were interpreted by GO, GSEA and signaling pathway analyses with Avadis NGS and PANTHER Classification System. Overall design: For RNA-Seq experiment, total RNAs of HPRT knockdown and control SNMs were extracted time-sequentially during the SNM differentiation such as differentiation-day 0, 1, 2, 3, 4, 6, 8, 10, 12, and 14 to final neurons, and each prepared library applied to the HiSeq 2000 sequencer of Illumina for 50 cycles of single lane run.
