Abstract
MicroRNAs (miRNAs) are small regulatory RNAs participating to several biological processes and known to be involved in various pathologies. Measurable in body fluids, miRNAs have been proposed to serve as efficient biomarkers for diseases and/or associated traits. Here, we performed a next-generation-sequencing based profiling of plasma miRNAs in 344 patients with venous thrombosis (VT) and assessed the association of plasma miRNA levels with several haemostatic traits and the risk of VT recurrence. Among the most significant findings, we detected an association between hsa-miR-199b-3p and haematocrit levels (P = 0.0016), these two markers having both been independently reported to associate with VT risk. We also observed suggestive evidence for association of hsa-miR-370-3p (P = 0.019), hsa-miR-27b-3p (P = 0.016) and hsa-miR-222-3p (P = 0.049) with VT recurrence, the observations at the latter two miRNAs confirming the recent findings of Wang et al. Besides, by conducting Genome-Wide Association Studies on miRNA levels and meta-analyzing our results with some publicly available, we identified 21 new associations of single nucleotide polymorphisms with plasma miRNA levels at the statistical significance threshold of P < 5 × 10-8, some of these associations pertaining to thrombosis associated mechanisms. In conclusion, this study provides novel data about the impact of miRNAs' variability in haemostasis and new arguments supporting the association of few miRNAs with the risk of recurrence in patients with venous thrombosis.

Abstract
BACKGROUND AND OBJECTIVE Platelets abundantly express glycoprotein CD36 with thrombospondin-1 (TSP1) and oxidized low-density lipoprotein (oxLDL) as proposed ligands. How these agents promote platelet activation is still poorly understood. METHODS AND RESULTS Both TSP1 and oxLDL caused limited activation of platelets in suspension. However, immobilized TSP1 and oxLDL, but not LDL, strongly supported platelet adhesion and spreading with a major role of CD36. Platelet spreading was accompanied by potent Ca(2+) rises, and resulted in exposure of P-selectin and integrin activation, all in a CD36-dependent manner with additional contributions of α(IIb) β(3) and ADP receptor stimulation. Signaling responses via CD36 involved activation of the protein tyrosine kinase Syk. In whole blood perfusion, co-coating of TSP1 or oxLDL with collagen enhanced thrombus formation at high-shear flow conditions, with increased expression on platelets of activated α(IIb) β(3), P-selectin and phosphatidylserine, again in a CD36-dependent way. CONCLUSIONS Immobilized TSP1 and oxLDL activate platelets partly via CD36 through a Syk kinase-dependent Ca(2+) signaling mechanism, which enhances collagen-dependent thrombus formation under flow. These findings provide novel insight into the role of CD36 in hemostasis.

Abstract
Statins have been reported to affect blood vessel formation. Thrombospondin-1 (TSP-1) is a multifunctional protein that affects vasculature systems such as platelet activation, angiogenesis, and wound healing. This study was designed to investigate the effect of atorvastatin on TSP-1 synthesis in thrombin-stimulated human umbilical vein endothelial cells (HUVECs), and its regulation by mevalonate or its derivatives. The results showed that atorvastatin down-regulated TSP-1 expression in HUVECs. This effect was fully reversed by mevalonate, farnesylpyrophosphate (FPP), and gerarylgeranylpyrophosphate (GGPP). Furthermore, farnesyltransferase and geranylgeranyltransferase inhibitors decreased TSP-1expression. It was also found that thrombin increased TSP-1 expression in HUVECs. Atorvastatin (0.1, 1, and 10 muM) decreased TSP-1 in thrombin-stimulated cells (45%, 66%, and 80%). Mevalonate partially reversed this inhibitory effect of atorvastatin on TSP-1, whereas the presence of FPP and GGPP did not alter TSP-1. Rho-kinase inhibitor neutralized the up-regulation of TSP-1 induced by thrombin. In conclusion, atorvastatin inhibits TSP-1 expression in endothelial cells via the mevalonate pathway. Rho protein activation is necessary for up-regulation of TSP-1 synthesis induced by thrombin. Because FPP and GGPP are essential for the activity of Rho proteins, inhibition of these proteins may constitute the mechanism by which atorvastatin inhibits thrombin up-regulated TSP-1 expression.

Abstract
Linker for activation of T cells (LAT) is an adaptor protein required for organization of the signaling machinery downstream of the platelet collagen receptor, the glycoprotein VI (GPVI). Here, we investigated the effect of LAT mutations on specific signaling pathways and on platelet functions in response to GPVI triggering by convulxin (Cvx). Using mice containing tyrosine to phenylalanine mutations of the adaptor, we show the crucial role played by the tyrosine residues at positions 175, 195, and 235 in the phosphorylation of LAT and in the whole pattern of protein tyrosine phosphorylation in response to Cvx. These 3 C-terminal tyrosine residues are important to recruit the tyrosine kinase Fyn, which may be involved in LAT phosphorylation. Efficient phosphoinositide 3-kinase (PI3K) activation requires the 3 C-terminal tyrosine residues of LAT but not its tyrosine 136. Interestingly, single mutation of the tyrosine 136 results in the loss of phospholipase C gamma2 (PLCgamma2) activation without affecting its PI3K-dependent membrane association, and is sufficient to impair platelet responses to Cvx. Thus, activation of PLCgamma2 via GPVI is dependent on 2 complementary events: its interaction with the tyrosine 136 of LAT and its membrane location, which itself requires events mediated by the 3 C-terminal tyrosines of LAT.

Abstract
Thrombospondin-1 (THBS1) is a large extracellular matrix glycoprotein that affects vasculature systems such as platelet activation, angiogenesis, and wound healing. Increases in THBS1 expression have been liked to disease states including tumor progression, atherosclerosis, and arthritis. The present study focuses on the effects of thrombin activation of the G-protein-coupled, protease-activated receptor-1 (PAR-1) on THBS1 gene expression in the microvascular endothelium. Thrombin-induced changes in gene expression were characterized by microarray analysis of approximately 11,000 different human genes in human microvascular endothelial cells (HMEC-1). Thrombin induced the expression of a set of at least 65 genes including THBS1. Changes in THBS1 mRNA correlated with an increase in the extracellular THBS1 protein concentration. The PAR-1-specific agonist peptide (TFLLRNK-PDK) mimicked thrombin stimulation of THBS1 expression, suggesting that thrombin signaling is through PAR-1. Further studies showed THBS1 expression was sensitive to pertussis toxin and protein kinase C inhibition indicating G(i/o)- and G(q)-mediated pathways. THBS1 up-regulation was also confirmed in human umbilical vein endothelial cells stimulated with thrombin. Analysis of the promoter region of THBS1 and other genes of similar expression profile identified from the microarray predicted an EBOX/EGRF transcription model. Expression of members of each family, MYC and EGR1, respectively, correlated with THBS1 expression. These results suggest thrombin formed at sites of vascular injury increases THBS1 expression into the extracellular matrix via activation of a PAR-1, G(i/o), G(q), EBOX/EGRF-signaling cascade, elucidating regulatory points that may play a role in increased THBS1 expression in disease states.

Abstract
Platelet adhesion to vascular collagens is an essential step in the initiation of hemostasis and thrombosis. Several platelet receptors interact with type I and type III collagens, including GP Ia/IIa and GP VI. We recently described a new platelet receptor (TIIICBP) specific for a type III collagen-related primary binding sequence, the KOGEOGPK octapeptide. Here, we characterize platelet adhesion to the immobilized octapeptide and demonstrate that this adhesion 1) is Ca2+ and Mg2+ independent, suggesting a noninvolvement of GP Ia/IIa; 2) is not inhibited by an antibody against GP VI; and 3) triggers platelet protein tyrosine phosphorylation. Whereas TXA2 has minimal effects, released ADP via only P2Y12 potentiates platelet adhesion to the octapeptide. Octapeptide-induced platelet adhesion triggers platelet signaling through tyrosine phosphorylation of the 68 kDa subunit of TIIICBP, Syk, PLCgamma2, and FAK. Tyrosine phosphorylation of the FcR gamma-chain and LAT is also observed but to a lesser extent than with type III collagen, suggesting the requirement of GP VI for full tyrosine phosphorylation of FcR gamma-chain and LAT. The present study provides evidence for a critical role for the type III collagen-related KOGEOGPK octapeptide in mediating platelet adhesion and signaling, and consequently in platelet-collagen interactions.-

Abstract
Thrombospondin-1 (TSP-1) is a large matricellular glycoprotein secreted by many cell types. It is a component of the extracellular matrix during active and subacute processes. Due to TSP-1's ability to interact with a variety of matrix proteins and cell-surface receptors, controversy exists about its conflicting functions. In this review, we will discuss the role of TSP-1 in human disease.

Abstract
Membrane microdomains enriched in glycosphingolipids, cholesterol, glycosylphosphatidylinositol-anchored proteins and Src-family kinases (lipid rafts, GEMs) appear to play many important roles, especially in immunoreceptor signaling. Most transmembrane proteins are excluded from these specialized areas of membranes, notable exceptions being several palmitoylated proteins such as the T cell coreceptors CD4 and CD8, and several recently described transmembrane adaptor proteins, LAT, non-T cell activation linker (NTAL)/linker for activation of B cells (LAB), phosphoprotein associated with GEMs (PAG)/Csk-binding protein (Cbp) and LIME. All these molecules possess a very short N-terminal extracellular peptide (4-17 amino acids), transmembrane segment followed by a palmitoylation motif (CxxC) and cytoplasmic domain containing up to 10 tyrosine residues potentially phosphorylated by the Src- or Syk-family kinases. Tyrosine-phosphorylated transmembrane adaptors bind (directly via SH2 domains or indirectly) other signaling molecules such as several cytoplasmic adaptors and enzymes. LAT is indispensable for TCR signaling (and participates also at signal transduction initiated by some other receptors), NTAL/LAB appears to play a LAT-like role in signaling initiated by BCR and some Fc-receptors; PAG/Cbp cooperates with Csk, the cytoplasmic tyrosine kinase negatively regulating Src-family kinases. Additional transmembrane adaptors exist (TRIM, SIT, LAX) that are however not palmitoylated and therefore excluded from the lipid rafts; structurally and functionally, the zeta-chain family proteins tightly associated with immunoreceptors and activating NK-receptors may be also considered as transmembrane adaptors.
