Effects of Smoldering Eucalyptus Wood Smoke Extract on Primary Human Brain Microvascular Endothelial Cells (HBMEC) and Immortalized Human Cerebral Microvascular Endothelial Cell Line (hCMEC/D3)

Project description:Increase in frequency and size of wildfire raises a significant public health concern due to rapid climate change. Epidemiological studies have shown that wildfire smoke exposure can increase the risk of neurological disorders. Our study aims to understand how wildfire smoke particles affect brain endothelial cells using both primary human brain microvascular endothelial cells (HBMEC) and an immortalized human cerebral microvascular endothelial cell line (hCMEC/D3). HBMEC and hCMEC/D3 were exposed to different levels of smoldering eucalyptus smoke particles (10, 30, 50 ug/mL) for 24 hr. Supernatants were collected for LDH and ELISA array, cell lysates were collected for RNAseq, and cells were fixed and stained for tight junction marker (Zonula Occludens-1, ZO-1) via ICC. Our study found that treatment to smoldering eucalyptus particles can increase inflammatory cytokine production dose-dependently in HBMECs and hCMEC/D3. Moreover, RNAseq analyses resulted in dose-dependent changes in HBMEC and hCMEC/D3 from wood smoke treatment that could be mediated via AhR and Nrf2 pathways.

Proteomic profiling of hCMEC/D3 cells exposed 3 days to laminar physiological shear stress

Project description:Endothelial cells (ECs) are constantly submitted in vivo to hemodynamical forces derived from the blood circulation, including shear stress (SS). EC are able to detect SS and consequently adapt their phenotype, thus affecting many endothelial functions. If a plethora of shear stress-regulated molecular networks have been described in peripheral EC, less is known about the molecular responses of microvascular brain ECs which constitute the blood-brain barrier (BBB). In this work, we investigated the response of human cerebral microvascular ECs to laminar physiological shear stress using the well characterized hCMEC/D3 cell line. Interestingly, we showed that hCMEC/D3 cells responded to shear stress by aligning perpendicularly to the flow direction, contrary to peripheral endothelial cells which aligned in the flow direction. Whole proteomic profiles were compared between hCMEC/D3 cells cultured either in static condition or under 5 or 10 dyn.cm-2 SS for three days. 3592 proteins were identified and expression levels were significantly affected for 3% of them upon both SS conditions. Pathway analyses were performed which revealed that most proteins overexpressed by SS refer to the antioxidant defense, probably mediated by activation of the NRF2 transcriptional factor. Regarding down-regulated proteins, most of them participate to the pro-inflammatory response, cell motility and proliferation. These findings confirm the induction of EC quiescence by laminar physiological SS and reveal a strong neuroprotective effect of SS on hCMEC/D3 cells, suggesting a similar effect on the BBB. Our results also showed that SS did not significantly increase expression levels nor did it affect the localization of junctional proteins or the functional activity of several ABC transporters (P-glycoprotein and MRPs). This work provides new insights on the response of microvascular brain EC to SS and on the importance of SS for optimizing in vitro BBB models.

Marinobufagenin regulates gene expression in human brain microvascular endothelial cells in vitro.

Project description:To understand the mechanism by which MBG increases permeability of human brain microvascular endothelial cell (HBMEC) monolayers, the primary cultures were treated with 10nM MBG for 12 h. RNA was isolated and analysed for gene expression on Agilent one color microarrays. Triplicate wells of HBMEC were treated with 10 nM MBG in DMSO or with just the drug vehicle for 12 h. RNA was isolated from each well and used to reverse transcribe and generate Cy3-labelled cRNA. Microarrays were hybridized, washed and scanned. Data were normalized and assessed for differential gene expression between MBG treated and control HBMEC.

Transcriptome sequencing analysis for NCI-H209 lung tumor cells conditioned by human brain microvascular endothelial cells

Project description:Endothelial cells of blood vessel playing a key role in the metastasis of tumor cells particularly the brain microvascular endothelial cells in the brain-tropic metastasis of lung tumor cells. Currently, studies towards the influence contributed by tumor cells to the alteration of endothelial cells have been extensively conducted by contrast studies for the alteration of gene-expression signature of tumor cells under the influence of endothelial cells remains poorly characterized, thus in this study the transcriptome of the human small-cell lung cancer cell NCI-H209 was sequenced via RNA-Seq after conditioned by human brain microvascular endothelial cell (HBMEC) for characterizing the alteration of gene-expression signature.

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.
