Physiological profile of the coronary artery and internal thoracic artery endothelial cells as a basis for the structural and functional congrunce of the arterio-arterial continuum

ABSTRACT: Currently, it is well established that human endothelial cells (ECs) are characterised by a significant heterogeneity between distinct blood vessels, e.g., arteries, veins, capillaries, and lymphatic vessels. Further, even ECs belonging to the same lineage but grown under different flow patterns (e.g., laminar and oscillatory or turbulent flow) ostensibly have distinct molecular profiles defining their physiological behaviour. Human coronary artery endothelial cells (HCAEC) and human internal thoracic artery endothelial cells (HITAEC) represent two cell lines inhabiting atheroprone and atheroresistant blood vessels (coronary artery and internal thoracic artery, respectively). Resistance of the internal mammary artery to atherosclerosis has been largely attributed to the protective phenotype of HITAEC which reportedly produce higher amounts of vasodilators including nitric oxide (NO) through the respective signaling pathways. However, this hypothesis has not been adequately addressed hitherto as proteomic profiling of HCAEC and HITAEC in a head-to-head comparison setting has not been performed.

A primate nigrostriatal atlas of neuronal vulnerability and resilience in a model of Parkinson’s disease

Project description:The degenerative process in Parkinson’s disease (PD) causes a progressive loss of dopaminergic neurons (DaNs) in the nigrostriatal system. Resolving the differences in neuronal susceptibility warrants an amenable PD model that, in comparison to post-mortem human specimens, controls for environmental and genetic differences in PD pathogenesis. At present study, we generated a primate model of PD by carotid artery injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine MPTP and sampled substantia nigra and putamen of macaque for single cell sequencing analysis.

Radiation response in human cardiac endothelial cells investigated by DIA-MS

Project description:The endothelium is the barrier separating blood and tissue. Radiation-induced enhanced inflammation leading to permeability of this barrier may increase the risk of cardiovascular disease. The aim of this study was to investigate the onset of endothelial inflammatory pathways after radiation exposure. Human coronary artery endothelial cells (HCECest2) were exposed to radiation doses of 0, 0.25, 0.5, 2.0 and 10 Gy (60Co-γ). The cells were harvested 4 h, 24 h, 48 h and 1 wk post-irradiation. The proteomics analysis was performed in a label-free data-independent acquisition mode. The data were validated using bioinformatics and immunoblotting. The low- and moderate-dose-treated samples showed only small proteome changes. In contrast, an activation of DNA-damage repair, inflammation, and oxidative stress pathways was seen after high-dose treatments (2 and 10 Gy). The level of the DNA damage response protein DDB2 was enhanced early at the 10 Gy dose. The expression of proteins belonging to the inflammatory response or cGAS-STING pathway (STING, STAT1, ICAM1, ISG15) increased in a dose-dependent manner showing the strongest effects at 10 Gy after one week. This study suggests a connection between radiation-induced DNA damage and induction of inflammation and supports inhibition of cGAS-STING pathway in the prevention of radiation-induced cardiovascular disease.

MicroRNA expression data from human high-density lipoproteins.

Project description:We quantified differential microRNA (miRNA) expression on human HDL before and after incubation with human coronary artery endothelial cells. These data were used to determine which miRNAs are altered on HDL (taken up or effluxed to) by human coronary artery endothelial cells. Each group had a n=4 and HDL-miRNA levels post incubations were compared to pre incubations with cells.

Modelling Premature Cardiac Aging with Induced Pluripotent Stem Cells From a Hutchinson-Gilford Progeria Syndrome Patient

Project description:Hutchinson-Gilford Progeria Syndrome (HGPS) is a rare genetic disorder that causes accelerated aging and a high risk of cardiovascular complications. However, the underlying mechanisms of cardiac complications of this syndrome are not fully understood. This study modeled HGPS using cardiomyocytes (CM) derived from induced pluripotent stem cells (iPSC) derived from a patient with HGPS and characterized the biophysical, morphological, and molecular changes found in these CM compared to CM derived from a healthy donor. Electrophysiological recordings revealed that the HGPS CM was functional and had normal electrophysiological properties. Electron tomography showed nuclear morphology alteration and 3D reconstruction of electron tomography images indicated structural abnormalities in HGPS CM mitochondria. High-resolution respirometry with isolated CM derived from three distinct cellular differentiations suggests that HGPS-CM had a tendency of lower oxygen consumption capacity. However, there was no difference in mitochondrial content as measured by Mitotracker. Telomere length was measured using qRT-PCR, and no difference was found in either the iPSCs or the CM from HGPS when compared to the control. Proteomic analysis was carried out in a high-resolution system using Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS). The proteomics data show distinct group separations and protein expression differences between HGPS and control-CM, highlighting changes in ribosomal, TCA cycle, and amino acid biosynthesis, among other modifications. Our findings show that iPSC-derived cardiomyocytes from a Progeria Syndrome patient have significant changes in mitochondrial morphology and protein expression, implying novel mechanisms underlying premature cardiac aging

A Liver Hepcidin-Intestinal HIF-2α Axis Regulates Iron Absorption During Systemic Iron Deficiency, Hypoxia and Hemochromatosis

Project description:Iron-related disorders are among the most prevalent diseases worldwide. Systemic iron homeostasis requires hepcidin (Hamp), a hepatic-derived hormone that controls iron mobilization through its molecular target, ferroportin (FPN), the only known mammalian iron exporter. Here, we took a transcriptomic approach to to compare the duodenal transcriptome during systemic iron demand to that of hepcidin-deficiency iron overload. Hampfl/fl (control) and AlbCreERT2;Hampfl/fl mice were placed on iron-replete and low-iron diets and were sacrificed two weeks following tamoxifen treatment. Duodenum RNA expression was compared across genotypes and across iron-replete and low iron diets.

Transcription factor activator protein 2C (TFAP2C) regulates luminal differentiation in mammary development and carcinogenesis

Project description:Molecular subtypes of breast cancer are characterized by patterns of gene expression, which can be used to predict response to therapy and overall clinical outcome. The luminal breast cancer subtypes are defined by the expression of ER-alpha (ERa) and a set of ERa-associated genes. The transcription factor activator protein 2C (TFAP2C, AP-2C, AP-2g) transcription factor plays a critical role in regulating cell growth and differentiation during ectodermal development and has been implicated in the regulation of ERa and other luminal-associated genes in breast cancer. While TFAP2C has been established as a prognostic factor in human breast cancer, the role of TFAP2C in development of the luminal epithelial cells in the normal mammary gland and in breast cancer have remained elusive. Herein, we demonstrate a critical role of TFAP2C in maintaining the luminal differentiation phenotype during normal mammary development and in luminal breast carcinoma cell lines. Total RNA from MCF7 cells with and without knockdown of TFAP2c. 3 biological replicates, with 2 technical replicates each, were performed for each sample type.

Regulation of Zn and Fe transporters by the GPC1 gene during wheat monocarpic senescence

Project description:TaGPC1 and TaGPC2 are NAC-domain transcription factors which accelerate the onset of senescence and facilitate nutrient translocation in wheat. We developed knockout mutants of these genes in tetraploid wheat and used RNA-seq to identify the effect of these mutations on the wheat flag leaf transcriptome during monocarpic senescence. Several transporter-related genes were identified which were upregulated during senescence and differentially expressed between genotypes. Illumina cDNA libraries were constructed from four biological replicates of three genotypes (WT, gpc-a1 and gpc-a1/gpc-b2) at three timepoints (Heading date, 12 days after anthesis and 22 days after anthesis). Reads were aligned to a collection of assembled genomic contigs from flow-sorted chromosome arms (A and B genomes only) provided by the International Wheat Genome Sequencing Consortium. A custom GTF file was generated to identify 139828 gene loci corresponding to transcribed regions of this reference sequence. Please note that the contig names provided by URGI (http://wheat-urgi.versailles.inra.fr/Seq-Repository) were used in the analysis. Most, but not all, of these loci are present in Ensembl (With a modified name, but the same basic information, chromosome arm and unique contig ID) at ftp://ftp.ensemblgenomes.org/pub/plants/release-22/fasta/triticum_aestivum/dna/ Therefore, the contig IDs from URGI (which are available for all our sequences) were used in the processed data file (i.e. the count table and GFF file) and an additional file describing the corresponding Ensembl names for these was provided (Additional_file_2.xlsx).

TLR2/6 agonists and IFNgamma induce CXCL10 from melanoma

Project description:Clinical approaches to treat advanced melanoma include immune therapies, whose benefits depend on tumor-reactive T-cells to infiltrate metastases. However, most tumors lack significant immune infiltration prior to therapy, and some immune therapies are hindered by a persistent lack of immune cell infiltration. CXCL10 has been implicated as a critical chemokine supporting T-cell migration into tumors; thus agents that induce CXCL10 in tumors may improve patient responses to systemic immune therapy. We find that melanoma cells treated with TLR2/6 agonists (MALP-2 or FSL-1) and interferon-gamma (IFNgamma) upregulate CXCL10 production, when compared to IFNgamma treatment alone or no treatment. Gene profiling of melanoma cells lines treated with TLR2/6 agonists and IFNgamma demonstrate that a selective profile of genes are induced which may be favorable for promoting immune cell infiltration of tumors. TLR2 and TLR6 are widely expressed on human melanoma cells, and treatment of melanoma cells with TLR2/6 agonists and IFNgamma does not hinder melanoma cell apoptosis or promote proliferation. Furthermore, melanoma cells from surgically resected patient tumors upregulate CXCL10 production after treatment with TLR2/6 agonists and IFNgamma when compared to treatment with either agent alone. Collectively, these data identify TLR2/6 agonists and IFNgamma as a novel target for promoting CXCL10 production directly from melanoma cells. Samples from four human melanoma cell lines, VMM1 (n=6), DM13 (n=6), DM93 (n=6) and VMM39 (n=6), were treated with media alone, MALP-2 (TLR2/6 agonist), FSL-1 (TLR2/6 agonist), IFNgamma alone, MALP-2 and IFNgamma, or FSL-1 and IFNgamma.
