Project description:Much remains unknown about the signals that induce early mesoderm to initiate hematopoietic differentiation. Here we show that endoglin (Eng), a receptor for the TGFβ superfamily, identifies all cells with hematopoietic fate in the early embryo. These arise in an Eng+Flk1+ mesodermal precursor population at E7.5, a cell fraction also endowed with endothelial potential. In Eng knockout embryos, hematopoietic colony activity and numbers of CD71+Ter119+ erythroid progenitors were severely reduced. This coincided with severely reduced expression of embryonic globin and key BMP target genes including the hematopoietic regulators Scl, Gata1, Gata2 and Msx-1. To interrogate molecular pathways active in the earliest hematopoietic progenitors, we applied transcriptional profiling to sorted cells from E7.5 embryos. Eng+Flk-1+ progenitors co-expressed TGFβ and BMP receptors and target genes. Furthermore, Eng+Flk-1+ cells presented high levels of phospho-SMAD1/5, indicating active TGFβ and/or BMP signaling. Remarkably, under hematopoietic serum-free culture conditions, hematopoietic outgrowth of endoglin-expressing cells was dependent on TGFβ superfamily ligands: BMP4, BMP2, or TGF-β1. These data demonstrate that the E+F+ fraction at E7.5 represents mesodermal cells competent to respond to TGFb1, BMP4, or BMP2, shaping their hematopoietic development, and that endoglin is a critical regulator in this process by modulating TGF/BMP signaling. E7.5 pooled embryos (25 litters; 300 embryos approximately) were dissected and 3,000 cells were sorted in triplicate for Eng-Flk1-, Eng-Flk1+, Eng+Flk1+, and Eng+Flk1- fractions. Microarray results were analyzed with GeneSpring GX software.

Project description:There are histological and functional differences between human deciduous and permanent pediodontal ligament (PDL) tissues. The purpose of this study was to determine the differences between these two types of tissue at the molecular level by comparative gene expression analysis. PDL samples were obtained from permanent premolars (n=38) and anterior deciduous teeth (n=31) extracted from 40 healthy persons. Comparative cDNA microarrary analysis revealed several differences in gene expression between the deciduous and permanent PDL tissues.

Project description:The goal of this study is to investigate the differential transcripted genes affected by CRISPR induced endoglin knockout in PASMC cells. Total RNA was purified from NTC or ENG-/- PASMC cells using RNeasy Mini Kit (Qiagen, Hilden, Germany). RNA quality and concentration were assessed with Agilent Tapestation 200 (Agilent Technologies) and Qubit 2.0 (ThermoFisher Scientific). ~250-500 ng RNA were used for library construction. The NGS libraries were constructed using the KAPA Stranded mRNA-Seq Kits (KapaBioSystems). mRNA was captured using magnetic oligo-dT beads and 1st strand cDNA was synthesized using random priming. In order to preserve strand-specificity, 2nd strand synthesis, which converts the cDNA:RNA hybrid to double-stranded cDNA (dscDNA), was marked by dUTP incorporation. cDNA framents were A-tailed by adding dAMP to the 3'-ends of the dscDNA library fragments. dsDNA Illumina TruSeq "forkedâ adapters 3'-dTMP overhangs were then ligated to A-tailed library insert fragments. Each of the six libraries were ligated with a unique Truseq 6bp barcode. Library fragments were amplified using the KAPA HiFi HotStart polymerase. The strand marked with dUTP was not amplified, allowing strand-specific sequencing. Fragment length and library quality was assessed on a 2100 Bioanalyzer using the High Sensitivity DNA Kit (Agilent Technologies). Libraries were diluted to 10nM and pooled at equimolar ratios. The pool was then diluted to 2nM and denatured in NaOH following Illumina recommendations. 10pM of denatured library pool was loaded in one HiSeq lane and flowcell was clustered on the Illumina C-bot. 5% PhiX control was spiked-in. The flowcell was sequenced on a HiSeq 2500 V4 chemistry with 50bp Single read protocol. Data was demultiplexed and Fastq files were generated using BcptoFastq 1.8.4 script provided by Illumina.

Project description:The aim of this study was to evaluate and compare the gene expression profiles of dental follicle and periodontal ligament in humans, which can possibly explain their functions of dental follicle and PDL such as eruption coordination and stress resorption. That may apply this information to clinical problem like eruption disturbance and to periodontal tissue engineering. PDL samples were obtained from permanent premolars (n=11) and dental follicle samples were obtained during extraction of supernumerary teeth (n=4). Comparative cDNA microarray analysis revealed several differences in gene expression between permanent PDL and dental follicles.

Project description:Analysis of embryonic sten cell-derived embryoid bodies following endoglin knock out. Loss of endoglin leads to profound reduction of key hematopoietic regulators including SCL, LMO2, Gata2, and TGF-β signaling molecule ALK-1. Results provide insight into molecular mechanisms underlying hemangioblast and primitive hematopoietic development.

Project description:Physiological functions of periodontal ligament (PDL) include anchorage, force absorption,and proprioceptive information. Despite the knowledge about biology of PDL cells, there is a lack of information regarding the molecular signature of permanent (PermPDL) and deciduous (DecPDL) PDL tissues. The present study was designed to characterize the membrane proteome of DecPDL and PermPDL primary cells (n=6) by a label-free quantitative proteome.

Project description:Endoglin is a 180-kDa glycoprotein receptor primarily expressed by the vascular endothelium and involved in cardiovascular disease and cancer. Heterozygous mutations in the endoglin gene (ENG) cause Hereditary Hemorrhagic Telangiectasia type 1, a vascular disease that present with nose and gastrointestinal bleeding, skin and mucosa telangiectases, and arteriovenous malformations in internal organs. A circulating form of endoglin (alias soluble endoglin, sEng), proteolytically released from the membrane-bound protein, has been observed in several inflammation-related pathological conditions and appears to contribute to endothelial dysfunction and cancer development through unknown mechanisms. Membrane-bound endoglin is an auxiliary component of the TGF-β receptor complex and the extracellular region of endoglin has been shown to interact with types I and II TGF-β receptors, as well as with BMP9 and BMP10 ligands, both members of the TGF-β family. To search for novel protein interactors, we have screened a microarray containing over 9,000 unique human proteins using recombinant sEng as bait. We find that sEng binds with high affinity, at least, to 22 new proteins. Among these, we have validated the interaction of endoglin with galectin-3, a secreted member of the lectin family with capacity to bind membrane glycoproteins, and with tripartite motif-containing protein 21 (TRIM21), an E3 ubiquitin-protein ligase. Using human endothelial cells and Chinese hamster ovary cells, we showed that endoglin co-immunoprecipitates and co-localizes with galectin-3 or TRIM21. These results open new research avenues on endoglin function and regulation.

Project description:Excessive MS is known to result in disappearance of the alveolar hard line, enlargement of thePDL space, and destruction of alveolar bone, leading to occlusal traumatism. The regulatory role of MS is believed to play a critical role in the process of alveolar bone remodeling. However, little is known about the effect of excessive MS on expression of osteoclastogenesis-related genes in human PDL cells. Human PDL cells were cultured in silicon chambers, which was attached to a stretching apparatus (STB-140; Strex Co. Ltd., Osaka, Japan) The cells were allowed to attach to the chamber base for 48 hours, after which uniaxial sinusoidal stretching (conditions: 60 sec/returns, resting time; 29 sec, stretch length; 1.6 mm, stretch ratio; 105%) was applied at 37°C, 5% CO2. We compared to the genes expression between 0 and 48 hours after MS stimulation.
