NTRAS hnRNPL RNA sequencing in HUVECs

ABSTRACT: In the current project with aim to unequivocally characterize a novel splicing-regulatory network that proves to be a central mediator of endothelial barrier function and vascular integrity. At the core of this network is the endothelial enriched lncRNA NTRAS (annotated as RP11-354k1.1) is shown to control alternative splicing decisions in HUVECs through interplaying with splicing factor hnRNPL. Specifically, in the project we show that NTRAS sequesters the splicing factor hnRNPL through a CA dinucleotide motif, to enhance TJP1 exon 20 usage, thereby TJP1α+ isoform. In turn disrupting TJP1α+ isoform expression impaired endothelial barrier function. Collectively, this splicing-regulatory network might prove fundamental in unlocking new interventions strategic to prevent or reverse vascular leakage.

Endothelial inhibition of the glycolytic activator PFKFB3 induces tumor vessel normalization, impairs metastasis and improves chemotherapy

Project description:Abnormal tumor vessels promote metastasis and impair chemotherapy. Hence, tumor vessel normalization (TVN) by targeting endothelial cells (ECs) is emerging as anti-cancer treatment. Here, we show that tumor ECs (TECs) have a hyper-glycolytic metabolism, shunting glycolytic intermediates to nucleotide synthesis. EC haplo-deficiency or blockade of the glycolytic activator PFKFB3 did not affect tumor growth, but reduced cancer cell intra- and extravasation and metastasis by normalizing tumor vessels, which improved vessel maturation and perfusion. Mechanistically, PFKFB3 inhibition tightened the vascular barrier by reducing VE-cadherin endocytosis in ECs and rendering glycolytic pericytes more quiescent; it also lowered the expression of cancer cell adhesion molecules in ECs. Additionally, PFKFB3-blockade treatment improved chemotherapy. Considering TEC metabolism for anti-cancer treatment might thus merit further attention.

Physiological shear stress markedly alters the proteomic response to hypoxia in human pulmonary microvascular endothelial cells

Project description:Physiological shear stress, produced by blood flow, homeostatically regulates the phenotype of pulmonary endothelial cells exerting anti-inflammatory and anti-thrombotic actions and maintaining normal barrier function. In the pulmonary circulation hypoxia, due to high altitude or diseases such as COPD, causes vasoconstriction, increased vascular resistance and pulmonary hypertension. Hypoxia-induced changes in endothelial function play a central role in the development of this pulmonary hypertension. However, the direct interactive effects of hypoxia and shear stress on the pulmonary endothelial phenotype have not been extensively studied. We cultured human pulmonary microvascular endothelial cells (HPMEC) in normoxia or hypoxia while subjected to physiological shear stress or in static conditions. Unbiased proteomics was used to identify hypoxia-induced changes in protein expression. Using publicly available single cell RNA-seq datasets, differences in gene expression between the alveolar endothelial cells from COPD and healthy lungs were identified. 60 proteins were identified in HPMEC lysates whose expression changed in response to hypoxia in sheared but not in static conditions. mRNA for five of these (ERG, MCRIP1, EIF4A2, HSP90AA1 and DNAJA1) showed similar changes in the endothelial cells of COPD compared to healthy lungs. These data show that the proteomic responses of the pulmonary microvascular endothelium to hypoxia are significantly altered by shear stress and suggest that these differences are important in the development of hypoxic pulmonary vascular disease.

Angiogenic and Immunologic Proteins Identified by Deep Proteomic Profiling of Human Choroidal and Retinal Vascular Endothelial Cells

Project description:PURPOSE Diseases that involve choroidal or retinal endothelial vascular cells are leading causes of vision loss: age-related macular degeneration, retinal ischemic vasculopathies and non-infectious posterior uveitis. Proteins differentially expressed by these endothelial cell populations are potential drug targets. We used deep proteomics to define the molecular phenotype of human choroidal and retinal endothelial cells at the protein level. METHODS Choroidal and retinal endothelial cells were separately isolated from 5 human eye pairs by selection on CD31. Total protein was extracted and digested, and peptide fractions were analysed by reverse-phase liquid chromatography tandem mass spectrometry. Peptide sequences were assigned to fragment ion spectra and proteins were inferred using public protein databases. Protein abundance was determined by spectral counting. Protein expression in choroidal versus retinal endothelial cells was compared using edgeR package in R, and annotation enrichment analysis was performed. RESULTS Human choroidal or retinal endothelial cells expressed 5042 non-redundant proteins. Setting the false discovery rate at 5%, 498 proteins (14.4%) of 3454 quantifiable proteins with minimum mean spectral counts of 2.5 were differentially expressed between cell populations. Choroidal and retinal endothelial cells were enriched in angiogenic proteins, and retinal endothelial cells were also enriched in immunologic proteins. CONCLUSIONS This work demonstrates the protein heterogeneity of human choroidal and retinal vascular endothelial cells and provides multiple candidates for further study as novel treatments or drug targets for posterior eye diseases.

Genome-wide analysis of each stage of EPCs differentiation

Project description:Analysis of regulators of endothelial progenitor cells (EPCs) differentiation at gene expression level. Results provide information of gene expression pattern and critical biological processing during EPCs differentiation. Taken together, we define the network of regulators of cord blood-derived EPCs during EPCs differentiation, which can be used to identify genes involved in vascular pathology. Furthermore, we select the critical regulators and then observe these selected regulator's functionality in vitro and in vivo. Total RNA obtained from isolated cord blood-derived EPCs at different time points after the beginning of the EPCs culture under endothelial differentiation condition.

Progerin Expression in Endothelial Cells Induces Endothelial Dysfunction

Project description:Hutchinson-Gilford Progeria Syndrome (HGPS) is a rare, genetic premature aging disorder associated with severe atherosclerosis, often resulting in fatal heart attacks and strokes. Progerin, the mutant protein in HGPS, also is expressed in healthy individuals and may play a role in the development of atherosclerosis during physiologic aging. Here, we provide evidence for a primary involvement of vascular endothelium in the pathogenesis of accelerated atherosclerosis in HGPS. Expression of progerin in cultured human endothelial cells induces a dysfunctional phenotype, manifested by activation of multiple pro-inflammatory, pro-atherogenic genes. In particular, our data implicate endothelial-derived interleukin-1 (IL-1) as a key mediator of a pro-inflammatory vascular phenotype. Endothelial activation also is detectable in a mouse model of HGPS, and appears to be conveyed to neighboring vascular cells via autocrine and paracrine signaling. These new mechanistic insights into the vascular pathobiology of HGPS may have therapeutic implications for this disease. Genome-wide transcriptional profiling was carried out to assess functional phenotypic changes in endothelial cells (EC) as a result of progerin expression. Cultured EC were infected with an adenovirus expressing progerin (Ad-Progerin), and as a control, an adenovirus that did not express any construct (Ad-Null). Experiments were preformed with three different EC cultures.

Physiological Vascular Permeability Requires Induction of Endothelial NR4A1 by Progesterone Receptor [ChIP-Seq]

Project description:Vascular permeability is frequently associated with inflammation and it is triggered by chemokines and by a cohort of secreted permeability factors, such as VEGF. In contrast, here we showed that the physiological vascular permeability that precedes implantation is directly controlled by progesterone receptor (PR) and it is independent of VEGF. Both global and endothelial-specific deletion of PR block physiological vascular permeability in the uterus while misexpression of PR in the endothelium of other organs results in ectopic vascular leakage. Integration of genome-wide transcriptional profile of endothelium and ChIP-sequencing revealed that PR induces a NR4A1 (Nur77/TR3) specific transcriptional program that broadly regulates vascular permeability in response to progesterone. This program triggers concurrent suppression of several junctional proteins and leads to an effective, timely and venule-specific regulation of vascular barrier function. Silencing NR4A1 blocks PR-mediated permeability responses indicating a direct link between PR and NR4A1. These results reveal a previously unknown function for progesterone receptor on endothelial cell biology with consequences to physiological vascular permeability and implications to the clinical use of progestins and anti-progestins on blood vessel integrity. Examination of PR binding sites in HUVEC cells using ChIP-seq (non-infected-negative control, PR infected followed by ligand treatment-PR+P or vehicle PR)

Conserved role of hnRNPL in alternative splicing of epigenetic modifiers enables B cell activation

Project description:The multifunctional RNA-binding protein hnRNPL has been implicated in antibody class switching but its broader function in B cells is unknown. Here, we show that hnRNPL is essential for B cell activation, and thereby germinal center and antibody responses. Upon activation, hnRNPL-deficient B cells show proliferation defects and increased apoptosis. The comparative analysis of RNA-seq data from B cells and another 8 hnRNPL-depleted cell types reveals a common function in the Myc and E2F transcriptional programs required for proliferation, likely borne out of a large alternative splicing change affecting multiple transcription regulators. Notably, while individual gene expression changes were cell type specific, several alternative splicing events affecting histone modifiers like SIRT1, KDM6A, and NSD2, were conserved across cell types, which could contribute to gene expression changes upon hnRNPL loss. SIRT1 reduction due to alternative splicing, and other transcriptional changes suggested mitochondrial defects in hnRNPL-deficient B cells. We confirmed dysfunctional mitochondria and ROS overproduction, which could explain the B cell activation defect. Thus, hnRNPL is essential for the resting to activated B cell transition by regulating transcriptional programs, most likely by splicing regulation affecting several histone modifiers.
