Abstract:

Protein arginine methyltransferase (PRMT) enzymes play a crucial role in RNA splicing, DNA damage repair, cell signaling, and differentiation. Arginine methylation is a prominent posttransitional modification of histones and various non-histone proteins that can either activate or repress gene expression. The aberrant expression of PRMTs has been linked to multiple abnormalities, notably cancer. Herein, we review a number of non-histone protein substrates for all nine members of human PRMTs and how PRMT-mediated non-histone arginine methylation modulates various diseases. Additionally, we highlight the most recent clinical studies for several PRMT inhibitors.

Abstract:

The three helical Histone Fold Motif (HFM) of core histone proteins provides an evolutionarily favored site for the protein–DNA interface. Despite significant variation in sequence, the HFM retains a distinctive structural fold that has diversified into several non-histone protein families. In this work, we explore the ancestry of non-histone HFM containing families in the plant kingdom. A sequence search algorithm was developed using iterative profile Hidden Markov Models to identify remote homologs of core-histone proteins. The resulting hits were functionally annotated, classified into families, and subjected to comprehensive phylogenetic analyses via Maximum likelihood and Bayesian methods. We have identified 4390 HFM containing proteins in the plant kingdom that are not histones, mostly existing as diverse transcription factor families, distributed widely within and across taxonomic groups. Patterns of homology suggest that core histone subunit H2A has evolved into newer families like NF-YC and DRAP1, whereas the H2B subunit of core histones shares a common ancestry with NF-YB and DR1 class of TFs. Core histone subunits H3 and H4 were found to have evolved into DPE and TAF proteins, respectively. Taken together these results provide insights into diversification events during the evolution of the HFM, including sub-functionalization and neo-functionalization of the HFM.

Abstract:

Abstract Non-epithelial intermediate filament (IF) subunit proteins show a high and specific affinity for core histones at physiological ionic strength. When IF proteins are titrated with a mixture of core histones and linker histone H1, in general the latter is totally excluded from com plexation and in the adducts formed the moderately-arginine-rich histones H2A and H2B are progressively replaced by the very-arginine-rich histones H3 and H4. At histone saturation, 2 molecules of nonneuronal IF protein bind 1 histone HI molecule or 8 core histone m olecules, whereas due to its glutamic acid rich, C terminal extensions one dimer of thp 68 kD npnrofilament nrotein associates with 3 molecules of histone H1 or 24 molecules of core histones. The salt stability of the insoluble association products is dependent on the amount and arginine content of the constituent histone species. Rem oval of the non-α-helical N- and C-terminal polypeptides from IF proteins by partial chymotryptic digestion does not affect their histone-binding characteristics. Since core histones are only partially inactivated by limited tryptic digestion, they also appear to react through their a-helix-rich central domains; the limit peptide derived from histone H1 is com pletely inactive at physiological ionic strength. Affinity chromatography of rod domains of IF proteins on core histone-Sepharose 4B and of histones and their limit peptides on vim entin-Sepharose 4B has shown that the interactions involving fractions of histones H3 and H4 are extrem ely resistant to salt and can be dissociated only with arginine or salt under denaturing conditions. In general, the experim ental results revealed close parallels between the association of histones with IF proteins and their interaction with DNA.

Abstract:

The possibility of interaction between linker histone H1 and non-histone chromatin protein HMGB1 was studied by intrinsic UV-fluorescence, far and near-UV CD and light scattering. The obtained data allow us to assume that the increase of histone H1 content in the HMGB1 solutions in a low ionic strength is accompanied by the destruction of HMGB1 associates. The interaction between proteins causes the increase of ordered regions in the protein molecules and the minor changes in their tertiary structure.

Abstract:

Histone deacetylases (HDACs) are a group of enzymes that regulate gene transcription by controlling deacetylation of histones and non-histone proteins. Overexpression of HDACs is found in some types of tumors and predicts poor prognosis. Five HDAC inhibitors are approved for the treatment of cutaneous T-cell lymphoma, peripheral T-cell lymphoma, and multiple myeloma. Treatment with HDAC inhibitors regulates gene expression with increased acetylated histones with unconfirmed connection with therapy. Apoptosis is a key mechanism by which HDAC inhibitors selectively kill cancer cells, probably due to acetylation of non-histone proteins. Ku70 is a protein that repairs DNA breaks and stabilizes anti-apoptotic protein c-FLIP and proapoptotic protein Bax, which is regulated by acetylation. HDAC inhibitors induce Ku70 acetylation with repressed c-FLIP and activated Bax in cancer cells. Current studies indicate that Ku70 is a potential target of HDAC inhibitors and plays an important role during the induction of apoptosis.

Abstract:

The functioning of DNA in the cell nucleus is ensured by a multitude of proteins, whose interactions with DNA as well as with other proteins lead to the formation of a complicated, organized, and quite dynamic system known as chromatin. This review is devoted to the description of properties and structure of the progenitors of the most abundant non-histone protein of the HMGB family—the HmgB1 protein. The proteins of the HMGB family are also known as “architectural factors” of chromatin, which play an important role in gene expression, transcription, DNA replication, and repair. However, as soon as HmgB1 goes outside the nucleus, it acquires completely different functions, post-translational modifications, and change of its redox state. Despite a lot of evidence of the functional activity of HmgB1, there are still many issues to be solved related to the mechanisms of the influence of HmgB1 on the development and treatment of different diseases—from oncological and cardiovascular diseases to pathologies during pregnancy and childbirth. Here, we describe molecular structure of the HmgB1 protein and discuss general mechanisms of its interactions with other proteins and DNA in cell.

Abstract:

Protein arginine methyltransferases (PRMTs) are a family of enzymes that can methylate protein arginine residues. PRMTs’ substrates include histones and a variety of non-histone proteins. Previous studies have shown that yeast Hmt1 is a type I PRMT and methylates histone H4 arginine 3 and several mRNA-binding proteins. Hmt1 forms dimers or oligomers, but how dimerization or oligomerization affects its activity remains largely unknown. We now report that Hmt1 can methylate histone H3 arginine 2 (H3R2) in vitro. The dimerization but not hexamerization is essential for Hmt1’s activity. Interestingly, the methyltransferase activity of Hmt1 on histone H3R2 requires reciprocal contributions from two Hmt1 molecules. Our results suggest an intermolecular trans-complementary mechanism by which Hmt1 dimer methylates its substrates.

Abstract:

Approximately five million United States (U.S.) adults are diagnosed with heart failure (HF), with eight million U.S. adults projected to suffer from HF by 2030. With five-year mortality rates following HF diagnosis approximating 50%, novel therapeutic treatments are needed for HF patients. Pre-clinical animal models of HF have highlighted histone deacetylase (HDAC) inhibitors as efficacious therapeutics that can stop and potentially reverse cardiac remodeling and dysfunction linked with HF development. HDACs remove acetyl groups from nucleosomal histones, altering DNA-histone protein electrostatic interactions in the regulation of gene expression. However, HDACs also remove acetyl groups from non-histone proteins in various tissues. Changes in histone and non-histone protein acetylation plays a key role in protein structure and function that can alter other post translational modifications (PTMs), including protein phosphorylation. Protein phosphorylation is a well described PTM that is important for cardiac signal transduction, protein activity and gene expression, yet the functional role for acetylation-phosphorylation cross-talk in the myocardium remains less clear. This review will focus on the regulation and function for acetylation-phosphorylation cross-talk in the heart, with a focus on the role for HDACs and HDAC inhibitors as regulators of acetyl-phosphorylation cross-talk in the control of cardiac function.

Abstract:

Abstract Lysine acetylation (Kac) is well known to occur in histones for chromatin function and epigenetic regulation. In addition to histones, Kac is also detected in a large number of proteins with diverse biological functions. However, Kac function and regulatory mechanism for most proteins are unclear. In this work, we studied mutation effects of rice genes encoding cytoplasm-localized histone deacetylases (HDAC) on protein acetylome and found that the HDAC protein HDA714 was a major deacetylase of the rice non-histone proteins including many ribosomal proteins (r-proteins) and translation factors that were extensively acetylated. HDA714 loss-of-function mutations increased Kac levels but reduced abundance of r-proteins. In vitro and in vivo experiments showed that HDA714 interacted with r-proteins and reduced their Kac. Substitutions of lysine by arginine (depleting Kac) in several r-proteins enhance, while mutations of lysine to glutamine (mimicking Kac) decrease their stability in transient expression system. Ribo-seq analysis revealed that the hda714 mutations resulted in increased ribosome stalling frequency. Collectively, the results uncover Kac as a functional posttranslational modification of r-proteins which is controlled by histone deacetylases, extending the role of Kac in gene expression to protein translational regulation.

Abstract:

Cell growth and proliferation are processes in the cell that must be tightly regulated. Transcription of ribosomal RNA and ribosomal biogenesis are directly linked to cell growth and proliferation, since the ribosomal RNA encodes for the majority of transcription in a cell and ribosomal biogenesis influences directly the number of proteins that are synthesized. In the work presented in this thesis, we have investigated the ribosomal RNA genes, namely the ribosomal DNA genes and the 5S rRNA genes, and their transcriptional regulation. One protein complex that is involved in RNA polymerase I and III transcription is the chromatin remodelling complex B‑WICH (WSTF, SNF2h, NM1). RNA polymerase I transcribes the rDNA gene, while RNA polymerase III transcribes the 5S rRNA gene, among others. In Study I we determined the mechanism by which B‑WICH is involved in regulating RNA polymerase I transcription. B‑WICH is associated with the rDNA gene and was able to create a more open chromatin structure, thereby facilitating the binding of HATs and the subsequent histone acetylation. This resulted in a more active transcription of the ribosomal DNA gene. In Study II we wanted to specify the role of NM1 in RNA polymerase I transcription. We found that NM1 is not capable of remodelling chromatin in the same way as B‑WICH, but we demonstrated also that NM1 is needed for active RNA polymerase I transcription and is able to attract the HAT PCAF. In Study III we investigated the intergenic part of the ribosomal DNA gene. We detected non-coding RNAs transcribed from the intergenic region that are transcribed by different RNA polymerases and that are regulated differently in different stress situations. Furthermore, these ncRNAs are distributed at different locations in the cell, suggesting that they have different functions. In Study IV we showed the involvement of B‑WICH in RNA Pol III transcription and, as we previously had shown in Study I, that B‑WICH is able to create a more open chromatin structure, in this case by acting as a licensing factor for c-Myc and the Myc/Max/Mxd network. Taken together, we have revealed the mechanism by which the B‑WICH complex is able to regulate RNA Pol I and Pol III transcription and we have determined the role of NM1 in the B‑WICH complex. We conclude that B‑WICH is an important factor in the regulation of cell growth and proliferation. Furthermore, we found that the intergenic spacer of the rDNA gene is actively transcribed, producing ncRNAs. Different cellular locations suggest that the ncRNAs have different functions.

Abstract:

Non-Small Cell Lung Cancer (NSCLC), which accounts for 80% of all lung cancer cases, is associated with resistance to chemotherapy and poor prognosis. Exploitation of NSCLC-upregulated pathways that can either be targeted by novel therapeutics or used to improve the tumour-delivery of current chemotherapeutics are required. Among the matrix metalloproteinases (MMPs) that are essential for tumour development, MMP10 is a potential candidate as a therapeutic target based on its expression and contribution to NSCLC development. This research aims to explore the expression and functions of MMP10 in the tumour microenvironment of NSCLC and evaluate the potential of MMP10 as a target for therapeutic intervention. Herein, MMP10 expression at gene and protein levels were analysed in a panel of NSCLC cell lines using RT-PCR and Western blotting analysis. To determine MMP10 functional relevance, an in vitro angiogenesis assay using cell conditioned media was carried out. To identify specific peptide sequences for the design of prodrugs rationalised to be MMP10 activated, in vitro substrate cleavage studies were performed using a mass spectrometry approach to differentiate between MMP10 and the structurally similar MMP3. This study demonstrates that MMP10 is highly expressed in NSCLC and that high levels of MMP10 are associated with induction of angiogenesis, a crucial process supporting tumour growth. In addition to the achievement of having been able to differentiate between closely similar MMP3 and MMP10 through carefully monitoring the hydrolysis rate of compound 444259 (a known MMP substrate), data generated herein provides the basis for further studies to exploit MMP10 as a prodrug-activator.

Abstract:

AbstractThis chapter focuses on Harrison’s life prior to writing Animal Machines. Together with her siblings, Harrison was brought up in close contact to Britain’s cultural elite. After attending schools in London, Harrison commenced her university studies in 1939. The outbreak of war had a transformative impact on her life. Harrison was evacuated to Cambridge where she likely came into contact with ethologist William Homan Thorpe. She converted to Quakerism and subsequently enrolled in the Friends’ Ambulance Unit. The Quaker principles of non-violence, humanitarianism, and bearing witness to injustice would serve as important reference points throughout Harrison’s campaigning. After the war, she completed her studies in the dramatic arts but abandoned a potential career as a theatre producer. In 1954, she married architect Dexter Harrison. Similar to many Quakers, Harrison’s humanitarian concerns motivated her to become involved in the Campaign for Nuclear Disarmament and protest perceived technological, moral, and environmental threats to society.

Abstract:

AbstractThis chapter examines the evolution of British farm animal welfare politics during the last two decades of Harrison’s campaigning. In 1979, the RSPCA boycotted the Thatcher government’s new Farm Animal Welfare Council (FAWC). The short-lived protest triggered a membership revolt and moderation of RSPCA policies. It also coincided with a weakening of agricultural corporatism in Westminster. FAWC was granted relative independence from the Ministry of Agriculture, Fisheries, and Food and explicitly acknowledged an updated version of the five freedoms. Ensuing British welfare reforms were also driven by the increasing involvement of European bodies in animal welfare. Now in her 60s, Ruth Harrison joined FAWC as a welfare member. Her increasing public recognition as a senior welfare campaigner enabled her to proactively push for reforms, expand her fundraising activities, and sponsor additional welfare research. By the late 1990s, most of her welfare positions had become part of mainstream politics.

Abstract:

Idiopathic venous thrombosis and embolism have gained widespread interest since the discovery that, deficiencies of antithrombin III, protein C, and protein S are associated with familial venous thrombophilia. The purpose of our study was to obtain an estimate of the prevalence of this syndrome and to establish the etiology in as many cases as possible.We collaborated with specialists from 37 Dutch hospitals, covering about 10% of the Dutch population. A history as well as blood samples were obtained from 113 unrelated cases with familial thrombophilia and from 90 isolated cases. Assuming that each proband in a family with thrombophilia has an average of four affected relatives, a rough estimate of the prevalence of familial thrombophilia in The Netherlands is 40 cases per 100.000. The prevalence of non-familial thrombophilia is probably lower.In 35 out of the 113 familial cases we established a diagnosis of hereditary antithrombin III deficiency (n=5), protein C deficiency (type I: n=9; type II: n=4), protein S deficiency (n=15) and dysfibrinogenemia (n=2). In 36 cases we found no abnormality at all and in the remaining 42 cases abnormalities were found in one or more of the following: heparin cofactor II, factor V, factor VII, factor VIII, von Willebrand factor, plasminogen, tissue plasminogen activator, plasminogen activator inhibitor, alpha 2 antiplasmin and histidine rich glycoprotein. In most of these cases, however, the hereditary nature of the abnormalities could not be demonstrated and the causal relationships remain to be established.In the 90 isolated cases, we diagnosed hereditary deficiencies of anti thrombin III, protein C and protein S each in one case and a lupus anticoagulant in two cases. In 54 cases no abnormality was found and in the remaining 31 cases various abnormalities were found in one or more of the proteins mentioned above.We conclude that the syndrome of thrombophilia is not rare but its true prevalence needs to be established by more rigorous means. An etiological diagnosis can be made with confidence in only one third of the familial cases and in less than 10 percent of the isolated cases.

Abstract:

Arterial and venous thrombosis frequently occur in patients with lupus anticoagulant. We investigated in patients with lupus anticoagulant the possible association between protein S:Ag deficiency and/or anticardiolipin antibodies and a history of thrombosis. In 27 patients (8 with and 19 without a history of thromboembolic disease) free protein S:Ag was determined with immunoelectrophoresis in PEG 8000 precipitated plasma. Anticardiolipin antibodies were measured in 22 patients (10 with thromboembolism) by means of a solid phase radioimmunoassay.Free plasma protein S:Ag was normal or elevated in 25 patients and slightly decreased (protein S:Ag 67%) in 2 patients without thromboembolism. 2-dimensional electrophoresis revealed a normal distribution of the free and of the complexed form of protein S:Ag. Anticardiolipin antibodies were found in 6 out of 10 patients with a history of thrombosis (5 of 7 with venous thrombosis, 1 of 1 with cerebral infarction , none of 2 with combined venous and arterial thromboembolism) and in 4 out of 12 patients without a history of thrombosis.We conclude 1. the thrombophilic state in patients with lupus anticoagulant cannot be explained by a reduction of protein S:Ag, and 2. there seems to be no correlation between the presence or absence of anticardiolipin antibodies and the development of thromboembolic disease.

Abstract:

Prothrombin Madrid, a mutant prothrombin, was detected in a patient with a excessive bleeding history. The defect was characterized by a low coagulant activity contrasting with a normal level of prothrombin antigen in plasma. Activation of the purified protein was impaired by the absence of one of the two factor Xa catalyzed cleavages, generating meizothrombin which expressed a thrombin-like activity but was inactive on fibrinogen (Guillin et al., Ann. N.Y. Acad. Sci. 370:414, 1981). Prothrombin and prothrombin Madrid were isolated directly from plasma, with high yield, by immunoaffinity chromatography using conformation specific antibodies immobilized on Sepharose. After reduction and alkylation, purified proteins were hydrolyzed by trypsin. Resulting peptides were separated by reverse phase HPLC. Comparison of the two peptide maps showed that the prothrombin Madrid digest contained an additional peptide, identified by automated Edman degradation as residues 269 to 287 in prothrombin with the substitution of cysteine for arginine at position 273. Peptide 274—287, present in the prothrombin digest, was missing in the prothrombin Madrid digest. The mutation, precluding cleavage by factor Xa and normal generation of thrombin, is identical to the one described for prothrombin Barcelona. The two patients families are not related, raising the possibility that the gene coding for the cysteine 273 mutation in prothrombin is more common than anticipated. Of the seven mutants of vitamin E-dependant blood clotting proteins structurally characterized to date, three are functionally defective due to the presence of the propeptide on the mature amino-ternfinus (factor IX Cambridge, Oxford 3 and San Dimas) and three are due to an alteration that precludes zymogen activation (faotor TX Chapel Hill, prothrombin Barcelona and Madrid). This sample remains too small to anticipate the different classes of point mutations seen in the human population but functional abnormalities of protein processing, metal and lipid binding, zymogen activation, substrate recognition and enzyme catalysis will likely be important phenotypes. However genetic defects may be limited to a discrete group of point mutations that have significant functional implication for the proteins

Abstract:

Consecutive patients with a history of thrombo-embolic disease (n = 241, 109 males, 132 females, mean age 46 y), referred to the Coagulation Laboratory during an 18 month period, were analysed for defects in their coagulation and fibrinolytic systems. The diagnosis of thrombosis had been verified with phlebography and that of pulmonary embolus with scintigraphy or angiography. Retinal venous thrombosis was found in 15 of the patients. In 15 cases the thrombotic episodes occurred postoperatively, in 15 during pregnancy, in 12 during the postpartum period and in 20 during use of oral contraceptives. In the remaining cases no clinical riskfactors were identified.The concentration of protein C zymogen was measured with an immunoradiometric assay. Functional protein C was determined with a clotting inhibition assay. Protein C deficiency was found in 8 cases. Two of these had a functional protein C deficiency with normal zymogen levels. The concentration of total, as well as free (not in complex with C4b-binding protein), protein S was determined with a radioimmunoassay. Two cases of protein S deficiency were detected. Three patients with antithrombin III deficiency and two with plasminogen deficiency were found.The fibrinolytic activity after venous occlusion was analysed in 216 patients. Decreased levels were found in 32 %. The concentration of tissue plasminogen activator inhibitor (PAI) was measured in 110 patients and found to be increased in 65 % of the cases. In 99 patients both the fibrinolytic activity and the PAI concentration were measured. A combination of decreased fibrinolytic activity and increased levels of PAI was found in 44 cases. The concentration of tissue plasminogen activator antigen was decreased in 22 % of 105 cases analysed.Thus, in this material of patients with thrombo-embolic disease, abnormalities were found in 47 %. Defects in the fibrinolytic system were the most common findings. Protein C or protein S deficiency was diagnosed in less than 5 % of the cases.

Abstract:

Secretion of platelet granule constituents is closely associated with the phosphorylation of a cytosol polypeptide that we called P47 of Mr 47,000 (Imaoka, T. and Haslam, R.J., J. Biol. Chem. 258, 11404, 1983), by protein kinase C. Since the identity and function remains to be known, we purified protein kinase C, unphosphorylated and phosphorylated P47 to homogeneity from human platelets. Then precise phosphorylation reaction of P47 in vitro and a biological function of P47 were studied. Protein kinase C catalysed the phosphorylation reaction of P47 protein, platelet myosin light chain, histone III-S with Km of 0.8±0.2, 4.2±0.5, 4.7±0.7μM, and Vmax of 0.312, 0.189, 0.874 nmole/min/mg, respectively. Some data previously obtained in this laboratory and others utilizing histone III-S as substrate are consistent with the synergistic effect by diacylglycerol (DG) in the presence of Ca++ , phosphatidylserine (PS). Using P47 as substrate, the enzyme required both Ca++ and PS, but not DG for activity. 125I labelled unphosphorylated P47 had an ability to bind with platelet membrane fraction in the presense of phosphatidylserine. Effect of diacylglycerol was inhibitory in this PS dependent P47 binding with membrane. Unphosphorylated P47 had a inhibitory activity in platelet actin polymerization. Molar ratio to inhibit actin polymerization was 1:8(P47:actin). These activities were Ca++ independent. Purified 32P-labelled P47 lost the binding ability with membrane, also the inhibitory activity in actin polymerization.Therefore, we propose the hypothesis that unphosphorylated P47 may loosely bind with the inside of plasma membrane of platelet and inhibit actin polymerization as a modulator, when stimulated, protein Kinase C rapidly phosphorylate P47 and induce the activation of cytoskeletal network and subsequently release reaction. On the other hand, whether DG in fact can act as a second messenger remain uncertain, (supported by MESC of Japan)

Abstract:

The prevalence of inherited thrombotic syndromes in the general population (1 in 2,500/5,000) appears to be higher than that of inherited bleeding disorders. We have reviewed the problems of their diagnosis and propose a simple screening procedure. The most important candidates far. screening are patients with unexplained venous thromboembolism at ages ofless than 40 years, particularly when thrombotic episodes are recurrent.Screening must start from collectionof the clinical and family history of the propositus and from the exclusion of common acquired forms of thrombophilia. A negative family historydoes not exclude inherited thrombophilia, because the defects have oftena low penetrance and fresh mutationsmay have occurred in the propositi. The test chosen for laboratoryscreening of inherited thrombotic syndromes must be limited in number, easy todo and, more importantly, their results should be clinically relevent Which defects should be screened and what type of methodology should be used? The table is intended to answerthese questions by proposing a two-step screening procedure.The tests included in the .first step of the screening are aimed at evaluating Laboratory screening of inherited thrombotic syndromes the most frequent and well established causes of inherited thrombophilia, —-antithrombin III, protein C. protein S.plasminogen and fibrinogen.FIRST STEP Antithrombin III (heparin cofactorI chromogenic assay)Protein C (Francis' clotting assay)Protein S(electroimmunoassay of total proteinSantigen)Plasminogen (chromogenic assay)Fibrinogen (clotting assay)SECONSTEP(Tran's functional assay) Plasminogen activator (fibrin plate assay before and after venous stasisor DDAVP)Plasminogen activator inhibitor(chromogenic assay)The tests offirst choice that we propose (see table) are in general functional assaysdetecting both type I and type IIdeficiencies and are simple enough tobecarried out even in non specialized laboratories.For protein S, however,this goal has not been achieved yet and only type I protein S deficiencycan be currently identified with immunoassays measuring total protein S antigen. Since a number of laboratories may still not have the facilities to perform protein C functional assays, they are advised to set up at least an immunoassay, since type I deficiencies are much more frequent than type II deficiencies. The tests included in the second step of the screening are aimed at detectingthe less common or less well established causes of thrombophilia, and should be carried out when the clinical history suggests the existence of inherited thrombophilia and yet the first step has failed to reveal any laboratory abnormality. Defective plasminogen activation can be evaluated by measuring plasminogen activator activity with the simple fibrin plate assay carried out before and after stimuli such as venous occlusion and/or DDAVP infusion. The parallel measurement of plasminogen activator inhibitor allows to distinguish cases of detective plasminogen activation due to high inhibitor levels. The measurement of heparin cofactor II should also be included in this battery of second-step screening tests.Using this screening procedure in95 propositi with juvenile venous thromboembolism, we have identified 7 kindreds with antithrombin III deficiency (5 type I and 2 type II) (7.5%),7 kindreds with protein C deficiency (1 type II) (7.5%), 5 kindredswith protein S deficiency (5%), 1 withhypoplasminogenemia (1%) and 1 with dysfibrinogenemia Milano II (1). Theremaining undiagnosed cases might bedue to as yet unidentified deficiencies or abnormalities of other antithrombotic mechanisms such as,for instance, endothelial thrombomodulin or the fibrinolysis enhancing property of the protein C-protein S system.
