MiR-155 promotes blood-brain barrier dysfunction in neuroinflammation (part 1)

ABSTRACT: Here, we investigated the time-course changes in the pattern of microRNA (miRNA) expression of TNFα and IFNγ-stimulated and unstimulated hCMEC/D3 cells, an immortalized human cerebral microvascular endothelial cell line. In order to investigate pro-inflammatory cytokine-induced changes in miRNA levels in hCMEC/D3 cells, we challenged brain endothelial cells with TNFα and IFNγ (100 ng/ml) for 2 h, 6 h and 24 h and determined microRNA expression in cytokine-stimulated and unstimulated cells

Determination of effects of propionate on gene expression in human cerebromicrovascular endothelial cell line hCMEC/D3

Project description:The experiment was designed to look at the effect (on gene expression) of exposing human cerebromicrovascular endothelial cell line hCMEC/D3 to propionate (3 micromolar) for 24 h, to determine if circulating metabolites have the potential to affect integrity of the blood-brain barrier.

MiR-155 promotes blood-brain barrier dysfunction in neuroinflammation (part 2)

Project description:Over-expression of miR-155 induces changes in the pattern of gene expression of hCMEC/D3 cells. hypothesis tested in the present study was that miR-155 constitute an important regulatory control of the brain endothelial response to inflammatory cytokines. To identify miR-155 target genes in brain endothelim that might be implicated in BBB dysfunction relevant to human disease, we then analysed changes in mRNA expression of hCMEC/D3 cells that overexpress miR-155 and results were contrasted to cells transfected with scrambled miR. To ectopically express miR-155 in hCMEC/D3 cells, 30 nM of pre-miR-155 and the siPORT Amine transfection agent (Applied Biosystems, Warrington, UK) were combined following the manufacturerM-bM-^@M-^Ys instructions.

Comparative genomic profile of human brain microvascular endothelial cells upon TWEAK or TNFα stimulation at 3h, 12h, and 24h

Project description:The molecular mechanisms playing a role in TWEAK versus TNFɑ signaling on cerebral microvascular endothelial cells are not well defined. Therefore, we aimed to identify gene expression changes in cultures of human brain microvascular endothelial cells (hCMEC/D3) to address changes initiated by TWEAK exposure. Although related, these two cytokines mediated different effects on gene expression and on canonical pathway activation. We used Agilent Whole Human Genome Microarray 4X44K to compare TWEAK- and TNFɑ-mediated changes in gene expression after 3h, 12h, and 24h incubation of these cytokines.

BBBomics - Human Blood Brain Barrier Transcriptomics Hub [RNA-seq]

Project description:Functional and structural dysfunction of the blood brain barrier (BBB) leads to severe alterations in brain physiology and is believed to trigger neurodegeneration. To investigate the molecular mechanisms driving the BBB dysfunction, very few human BBB cell culture models are available; of which, the human microvascular endothelial cell line (hCMEC/D3) is the most widely used. Thus far, array-based approaches or targeted seqeuncing based approaches have been employed to characterize the gene expression of the hCMEC/D3 model. However,The goal of this study is to perform deep transcriptomic sequencing of the BBB cell line and obtain features like gene expression, expressed single nucleotide variants, alternate splice forms, circular RNAs, long non-coding RNAs and micro RNAs. We have developed blood brain barriers transcriptomics landscape using RNA sequencing and micro RNA seqeuncing data obtained from replicates of hCMEC/D3 BBB cell line.

Characterization of secretomes from brain microvascular endothelial cells after ischemia

Project description:The human immortalized brain endothelial cell line hCMEC/D3 is considered an in vitro model of the blood-brain-barrier. We aimed to characterize changes in the secretome of hCMEC/D3 subjected to oxygen and glucose deprivation (OGD) by SILAC, in order to identify new proteins involved in ischemia-triggered blood-brain-barrier disruption and test their potential as blood biomarkers for ischemic stroke diagnosis. After SILAC analysis, 19 proteins were found differentially secreted between OGD and normoxia/normoglycemia conditions (Fold Change>|1.4| and peptide count≥2). Protein folding and nucleic acid binding were the main molecular functions and epithelial adherens junctions and aldosterone signaling appeared as the main canonical pathways represented by OGD-secreted proteins. ANXA1, CLUS, IGFBP2, PRDX3, TIMP2 and COL1A2 were replicated by western blotting in 9 independent cell cultures. Five replicated proteins were analyzed in human serum samples of 38 ischemic stroke patients compared to 18 stroke-mimicking conditions and 18 healthy controls by ELISA. IGFBP2 showed increased blood levels when strokes were compared with stroke-mimicking patients (p<0.1). In conclusion, we characterized changes in the secretome of hCMEC/D3 after an ischemic insult and highlighted some candidates to become biomarkers for ischemic stroke diagnosis related to blood-brain-barrier disruption.
