Identification and purification of vitamin K-dependent proteins and peptides with monoclonal antibodies specific for gamma -carboxyglutamyl (Gla) residues. (1/55)

Novel monoclonal antibodies that specifically recognize gamma-carboxyglutamyl (Gla) residues in proteins and peptides have been produced. As demonstrated by Western blot and time-resolved immunofluorescence assays the antibodies are pan-specific for most or all of the Gla-containing proteins tested (factors VII, IX, and X, prothrombin, protein C, protein S, growth arrest-specific protein 6, bone Gla protein, conantokin G from a cone snail, and factor Xa-like proteins from snake venom). Only the Gla-containing light chain of the two-chain proteins was bound. Decarboxylation destroyed the epitope(s) on prothrombin fragment 1, and Ca(2+) strongly inhibited binding to prothrombin. In Western blot, immunofluorescence, and surface plasmon resonance assays the antibodies bound peptides conjugated to bovine serum albumin that contained either a single Gla or a tandem pair of Gla residues. Binding was maintained when the sequence surrounding the Gla residue(s) was altered. Replacement of Gla with glutamic acid resulted in a complete loss of the epitope. The utility of the antibodies was demonstrated in immunochemical methods for detecting Gla-containing proteins and in the immunopurification of a factor Xa-like protein from tiger snake venom. The amino acid sequences of the Gla domain and portions of the heavy chain of the snake protein were determined.  (+info)

The role of coagulation abnormalities in the development of Perthes' disease. (2/55)

Recent reports have suggested an association between Perthes' disease and an underlying thrombophilic or hypofibrinolytic tendency. In Northern Ireland there is a high incidence of Perthes' disease (11.7 per 100,000 or 1 in 607 children) in a stable paediatric population. We reviewed 139 children with Perthes' disease and compared them with a control group of 220 aged- and gender-matched healthy primary schoolchildren with similar racial and ethnic backgrounds. There were no significant deficiencies of antithrombotic factors protein C, protein S, antithrombin III or resistance to activated protein C. A total of 53 (38.1%) of the children with Perthes' disease had a prolonged activated partial thromboplastin time (>38) compared with 13 (5.9%) of the control group (p < 0.001). Our findings have shown that using standard assays, thrombophilia secondary to antithrombotic factor deficiency or resistance to activated protein does not appear to be an aetiological factor for Perthes' disease. The cause of the prolonged activated partial thromboplastin time, usually associated with a clotting factor deficiency, is under further investigation.  (+info)

Factor V Leiden mutation, prothrombin gene mutation, and deficiencies in coagulation inhibitors associated with Budd-Chiari syndrome and portal vein thrombosis: results of a case-control study. (3/55)

In a collaborative multicenter case-control study, we investigated the effect of factor V Leiden mutation, prothrombin gene mutation, and inherited deficiencies of protein C, protein S, and antithrombin on the risk of Budd-Chiari syndrome (BCS) and portal vein thrombosis (PVT). We compared 43 BCS patients and 92 PVT patients with 474 population-based controls. The relative risk of BCS was 11.3 (95% CI 4.8-26.5) for individuals with factor V Leiden mutation, 2.1(95% CI 0.4-9.6) for those with prothrombin gene mutation, and 6.8 (95% CI 1.9-24.4) for those with protein C deficiency. The relative risk of PVT was 2.7 (95% CI 1.1-6.9) for individuals with factor V Leiden mutation, 1.4 (95% CI 0.4-5.2) for those with prothrombin gene mutation, and 4.6 (95% CI 1.5-14.1) for those with protein C deficiency. The relative risk of BCS or PVT was not increased in the presence of inherited protein S or antithrombin deficiency. Concurrence of either acquired or inherited thrombotic risk factors was observed in 26% of the BCS patients and 37% of the PVT patients. We conclude that factor V Leiden mutation and hereditary protein C deficiency appear to be important risk factors for BCS and PVT. Although the prevalence of the prothrombin gene mutation was increased, it was not found to be a significant risk factor for BCS and PVT. The coexistence of thrombogenic risk factors in many patients indicates that BCS and PVT can be the result of a combined effect of different pathogenetic mechanisms.  (+info)

Structural basis for inhibition promiscuity of dual specific thrombin and factor Xa blood coagulation inhibitors. (4/55)

BACKGROUND: A major current focus of pharmaceutical research is the development of selective inhibitors of the blood coagulation enzymes thrombin or factor Xa to be used as orally bioavailable anticoagulant drugs in thromboembolic disorders and in the prevention of venous and arterial thrombosis. Simultaneous direct inhibition of thrombin and factor Xa by synthetic proteinase inhibitors as a novel approach to antithrombotic therapy could result in potent anticoagulants with improved pharmacological properties. RESULTS: The binding mode of such dual specific inhibitors of thrombin and factor Xa was determined for the first time by comparative crystallography using human alpha-thrombin, human des-Gla (1--44) factor Xa and bovine trypsin as the ligand receptors. The benzamidine-based inhibitors utilize two different conformations for the interaction with thrombin and factor Xa/trypsin, which are evoked by the steric requirements of the topologically different S2 subsites of the enzymes. Compared to the unliganded forms of the proteinases, ligand binding induces conformational adjustments of thrombin and factor Xa active site residues indicative of a pronounced induced fit mechanism. CONCLUSION: The structural data reveal the molecular basis for a desired unselective inhibition of the two key components of the blood coagulation cascade. The 4-(1-methyl-benzimidazole-2-yl)-methylamino-benzamidine moieties of the inhibitors are able to fill both the small solvent accessible as well as the larger hydrophobic S2 pockets of factor Xa and thrombin, respectively. Distal fragments of the inhibitors are identified which fit into both the cation hole/aromatic box of factor Xa and the hydrophobic aryl binding site of thrombin. Thus, binding constants in the medium-to-low nanomolar range are obtained against both enzymes.  (+info)

The dynamics of thrombin formation. (5/55)

The central event of the hemostatic process is the generation of thrombin through the tissue factor pathway. This is a highly regulated, dynamic process in which thrombin itself plays many roles, positively and negatively its production and destruction. The hemostatic process is essential to normal physiology and is also the Achilles heel of our aging population. The inappropriate generation of thrombin may lead to vascular occlusion with the consequence of myocardial infarction, stroke, pulmonary embolism, or venous thrombosis. In this review, we summarize our present views regarding the tissue factor pathway by which thrombin is generated and the roles played by extrinsic and intrinsic factor Xa generating complexes in hemostasis and the roles of the stoichiometric and dynamic inhibitors that regulate thrombin generation.  (+info)

Thrombotic risk factors and extent of liver fibrosis in chronic viral hepatitis. (6/55)

BACKGROUND AND AIMS: Thrombosis of the small intrahepatic veins has been suggested to trigger liver tissue remodelling. We evaluated the prevalence of multiple thrombotic risk factors and their association with the extent of fibrosis in chronic viral hepatitis. METHODS: Ninety consecutive patients with chronic hepatitis B or C without malignancy, a history of venous thrombosis, or antiviral/immunosuppressive therapy within the last six months were included. Thrombophilic and coagulation factors were evaluated on the liver biopsy day. RESULTS: One or more thrombotic risk factors were found in 68% and > or =2 factors in 37% of patients. Higher necroinflammatory activity was independently associated with higher prothrombin time (p=0.003), alanine aminotransferase level (p=0.011), and histological staging (p=0.018). Patients with staging scores of 4-6 compared with those with scores of 0-3 more frequently had deficiency of protein C (24% v 3%; p=0.007), antithrombin III (28% v 5%; p=0.005), and plasminogen (19% v 2%; p=0.03), and a trend for more frequent activated protein C resistance (8% v 0%; p=0.075). The presence of > or =1 significant thrombotic risk factor was observed in 11/25 (44%) patients with staging scores of 4-6 and in 6/65 (9%) patients with scores of 0-3 (p<0.001), being the only variable independently associated with advanced staging (odds ratio 2.4, p=0.02). CONCLUSIONS: Thrombotic risk factors are frequently detected in patients with chronic viral hepatitis and the presence of > or =1 significant factor is associated with more advanced fibrosis. Whether the association of such thrombophilic conditions with advanced fibrosis is a primary or secondary phenomenon and whether their development in combination with local inflammation accelerate the progression of liver fibrosis need further evaluation.  (+info)

Mikamo Lecture: a radical view on the 'superfamily' of cardiovascular risk factors. (7/55)

Many risk factors for cardiovascular disease generate superoxide in the blood vessels and thereby impair endothelial function. To emphasize the critical role of oxygen radicals, this is a 'radical view' of those risk factors. It will be useful to organize risk factors into a 'superfamily', with consideration of mediators, mechanisms, and target organs. Studies are summarized which suggest that, in parallel with the impairment of endothelial vasomotor function, the thrombin/thrombomodulin/activated protein C anticoagulant mechanism, which requires endothelial thrombomodulin, is also impaired by atherosclerosis and improves during regression of atherosclerosis. Impairment of the anticoagulant mechanism may contribute to thrombosis in atherosclerotic arteries, and improvement of the anticoagulant mechanism during regression of atherosclerosis may reduce the risk of cardiovascular events.  (+info)

Time course of coagulation parameters, cytokines and adhesion molecules in Plasmodium falciparum malaria. (8/55)

We studied 38 patients with malaria tropica over a period of 5 days during antiparasitic therapy. Serum or plasma levels of interleukin (IL) 1beta, IL-6, IL-10, tumour necrosis factor-alpha (TNF-alpha), the soluble vascular adhesion molecule (sVCAM) and the soluble intracellular adhesion molecule (sICAM) were determined by enzyme-linked immunosorbent assay. Protein C and antithrombin III activity were analysed by chromogenic tests and protein S activity by a clotting test. Antithrombin III, protein C and protein S activity was significantly lower in patients with severe malaria and displayed a highly significant increase in activity over the time of evaluation. Levels of sVCAM and sICAM were increased for the whole study period, but no significant differences were found between severe and mild malaria cases. Serum IL-1beta, IL-6 and IL-10 levels were significantly higher in patients with severe malaria, whereas no significant differences were found for TNF-alpha. IL-6 and IL-10 decreased significantly over 5 days during schizontocidal therapy. Our data show an impairment of the coagulation system which correlates with pro-inflammatory cytokines and therefore with the severity of the disease.  (+info)

In hemophilia A (HA) patients, F8 gene-defects as genetic risk-factors for developing inhibitors to Factor VIII have been extensively studied. Here we provide estimates of inhibitor-risk associated with the patients Human Leukocyte Antigen (HLA). We used next generation sequencing for high-resolution HLA Class II typing of 997 HA patients. Using inhibitor prevalence reports from the My Life Our Future (MLOF) research repository, we calculated Odds Ratios (OR) for inhibitor development in a multivariate model considering HLA-DRB1/3/4/5, HLA-DPB1, HLA-DQB1, race, F8 pathogenic variant type, and age. Participants with 1 HLA variant (DPB1*02:02) had developed inhibitors at a higher rate while participants with 2 HLA variants (DRB1*04:07; DRB1*11:04) had developed inhibitors at a lower rate. Additionally, patients with missense variants had developed inhibitors at a lower rate and participants with large structural changes (|50 bp) had developed inhibitors at a higher rate (both compared to Intron 22
Title: PARP Inhibitor Development for Systemic Cancer Targeting. VOLUME: 7 ISSUE: 5. Author(s):Tomasz Zaremba and Nicola Jane Curtin. Affiliation:Newcastle University,Northern Institute for Cancer Research, Paul OGorman Building, Medical School, Framlington Place, Newcastle upon Tyne, NE2 4HH, UK.. Keywords:Base excision repair/single strand break repair, Poly(ADP-ribose) polymerase-1 (PARP-1), PARP inhibitors. Abstract: Poly(ADP-ribose) polymerase 1 (PARP-1) is a DNA-binding enzyme that is activated by DNA breaks, converting them into an intracellular signal via poly(ADP-ribosyl)ation of nuclear proteins. Negatively charged polymers of ADP-ribose (PAR) attached to PARP-1 itself and histones lead to chromatin relaxation, facilitating the access of base excision/single strand break repair proteins and activating these repair enzymes. PARP inhibitors have been developed to investigate the role of PARP-1 in cell biology and to overcome DNA repair-mediated resistance of cancer cells to cytotoxic ...

Objective: The antioxidant activity of vitamin E is derived primarily from alpha-tocopherol (α-T) and gammatocopherol (γ-T). Results of epidemiological studies have demonstrated an inverse relationship between vitamin E intake and coronary disease. However, the results of clinical trials using α-T are equivocal. We determined the effect of 5 weeks of 100 mg/d or 200 mg/d γ-T supplementation on thrombotic markers such as platelet reactivity, lipid profile and the inflammation marker C-reactive protein (CRP). Methods and results: Fourteen healthy subjects consumed 100 mg/day while 13 consumed 200 mg/d of γ-T and 12 received placebo (soybean capsules with less than 5 mg/d γ-T) in a double-blinded parallel study design. Fasting pre and post dose blood samples were analysed. Blood γ-T concentrations increased significantly (p,0.05) relative to dose during the intervention period. Both groups receiving active ingredients showed significantly lower platelet activation after supplementation ...
In this study, we used whole-genome array analysis and pharmacological reagents to identify PROCR as a potential Cn/NFAT-dependent gene in vascular smooth muscle. We corroborate the only report to date that vascular SMCs do express the protein C receptor (PROCR).15 More importantly, we validate our informatics approach and are the first to report Cn/NFAT signaling as a regulator of PROCR activation. We show PDGF-BB stimulation induced PROCR expression in a Cn/NFAT-dependent manner at both the transcriptional and translational levels. Mutation of a highly conserved NFAT binding motif significantly attenuated PROCR promoter activation, supporting the NFAT-dependent property of PROCR activity. In addition, PROCR expression is upregulated in vivo as a result of acute vascular injury, highlighting the potential role of PROCR in vessel restenosis.. Until the recent detection of PROCR in vascular SMCs, PROCR was believed to be expressed predominantly in ECs. Studies to date on PROCR transcription focus ...

Deficiency in coagulation factor VIII encoded by F8 results in the X-linked recessive bleeding disorder haemophilia A (HEMA). Here we describe the identification of a novel variant in the factor VIII gene, F8, in an adult male patient with severe haemophilia A. The patient was diagnosed in early childhood and subsequently co-infected with Hepatitis C and HIV acquired during early blood transfusion for haemophilia in the 1980ies. The identified F8 deletion, c.5411_5413delTCT, p.F1804del lies within a conserved part of the molecule, is predicted by bioinformatic software to be deleterious by the loss of Phenylalanine, and has not been previously described in any database. This novel F8 deletion as a cause of haemophilia A did not result in generation of inhibitory antibodies to Factor VIII treatment and may have impact on (prenatal) diagnosis, genetic counselling, and treatment decisions in the affected family as well as in other families diagnosed with this F8 mutation. Finally, this novel mutation
The purpose of this 52-week pilot R34 randomized, open-label, non-inferiority, cross-over study is to determine the feasibility of a large single dose Phase III study of hemophilia adult prophylaxis. The primary efficacy endpoint will be bleeding frequency. Secondary endpoints will include factor usage, joint range of motion, cost, quality-of-life, and inter-dose hypocoagulability by thrombin generation time and F.VIII activity will also be determined.

Acquired factor VIII (FVIII) inhibitor induces a bleeding disorder caused by specific antibodies to FVIII. The cause of approximately one fifth of cases can be attributed to autoimmune disorders, such as pemphigus. Here, we describe a case of refractory acquired FVIII inhibitor in a patient with primary pemphigus and its successful treatment with low-dose rituximab. Coagulation studies revealed a prolonged activated partial thromboplastin time, which could not be corrected with the mixing test. At the same time, the FVIII activity level was significantly reduced, and the FVIII inhibitor titer was elevated. A treatment regimen with prednisolone/cyclophosphamide followed by prednisolone/cyclosporine was used. The patient temporarily responded but then became resistant to these medicines. However, subsequent treatment with low-dose rituximab achieved considerable clinical and laboratory improvement in the same patient. Follow-up at 6 months revealed a low level of residual FVIII inhibitor activity ...
The presence of Factor VIII (FVIII) inhibitor prevents FVIII infusions from working properly and makes treatment of bleeding episodes very difficult. Having an inhibitor is a serious and life-threatening complication in patients with Hemophilia. The usual treatment of patients with FVIII inhibitors involves what is called immune tolerance induction (ITI). Immune Tolerance means that the body can accept infused FVIII and that FVIII is again effective in controlling bleeds. ITI involves giving high doses of FVIII regularly until the inhibitor disappears. This treatment is not always effective. The inhibitor persists in about 1 in 5 patients who undergo ITI. There are 2 types of FVIII concentrates: FVIII concentrates derived from human plasma, which contain VWF, and concentrates of FVIII without VWF. Both types of concentrates are commonly used to induce immune tolerance in patients with Hemophilia A. Retrospective studies on subjects who were treated with VWF containing Factor VIII concentrates ...
Rationale: Hemophilia A is a rare X-linked hereditary bleeding disorder in which the secondary hemostasis is affected by a deficiency in clotting factor VIII (FVIII). As a consequence, patients may suffer from excessive bleeding in response to minor (surgical) trauma or injury. In all hemophilia A patients, perioperative factor concentrate replacement therapy is required, aiming for physiological FVIII plasma levels during up to 6 weeks. In mild hemophilia A patients, surgical procedures are the main reason for intensive treatment with FVIII concentrates. Treatment with FVIII concentrates is effective, but highly expensive. On average, treatment with FVIII concentrates costs 17,520 per mild hemophilia A patient, per surgical procedure. Moreover, exposure to exogenous FVIII may cause the development of FVIII neutralizing antibodies. Recent studies have shown this incidence is higher than realized previously. Neutralizing antibodies are a major challenge in hemophilia A patients, as they lead to ...

How is Hemophilia diagnosed?. Blood tests can help determine whether your child has hemophilia. Genetic tests are available if you would like to know whether you are a carrier of Hemophilia. (Only females can be carriers.). ​Hemophilia is usually classified by its severity. There are three levels of Hemophilia, although they can overlap. The severity of the disease is defined by how much clotting factor is produced and in what situations bleeding most often occurs. Mild Hemophilia might not be recognized unless there is excessive bleeding after a major injury or surgery. In moderate Hemophilia, bleeding usually follows a fall, sprain or strain. With severe Hemophilia, bleeding may occur one or more times a week for no apparent reason.. The percentage of clotting factor in the blood remains the same throughout a persons life. All family members who have Hemophilia usually have similar forms.. ...

Acquired hemophilia is an extremely rare but life threatening hemorrhagic disease caused by autoantibodies directed coagulation factor VIII. Estimated management guidelines include rapid diagnosis, suppression of bleeding, and elimination of inhibitors by use of immunosuppressants. Plasma exchange is used restrictively as an adjuvant in order to lower the level of inhibitor. We report on a successful therapeutic experience with plasma exchange in a patient with refractory acquired hemophilia. After performance of the plasma exchange procedure, bleeding was controlled and results of coagulation tests showed improvement according to the decrease in levels of factor VIII inhibitor. (Korean J Blood Transfus 2012;23: 14-71 ...
The U.S. Food and Drug Administration today approved Hemlibra (emicizumab-kxwh) to prevent or reduce the frequency of bleeding episodes in adult and pediatric patients with hemophilia A who have developed antibodies called Factor VIII (FVIII) inhibitors.
Dabigatran dosage varied on basis of renal function (300 mg twice daily in those with a CrCl of 110 ml per minute or more, 220 mg twice daily in those with a CrCl of 70 to 109 ml per minute, 150 mg twice daily in patients with a CrCl less than 70 ml per minute) ensuring a trough level of 50 ng/ml or higher. If the levels were insufficient on higher Dabigatran dose or CrCl was , 30 ml/min patients were switched to a non-study anticoagulant. In the Warfarin group, INR was targeted to be 2-3 for aortic mechanical valve with no additional risk factors and 3-3.5 for mitral mechanical valve or aortic valve with additional thrombotic risk factors ...
The use of surrogates either as native orthologous proteins or as optimized chimeras, which can be readily crystallized and soaked with small molecules, has been validated by its success in other fields, particularly in guiding kinase inhibitor development (Ikuta et al., 2001; Breitenlechner et al., 2004). One should bear in mind, however, that the surrogate approach has its limitations, and local structural differences may have considerable effect on ligand binding (Davies et al., 2007). HIV-1 and PFV INs are fully orthologous, with identical canonical domain folds and stoichiometry. Fortuitously, all intasome atoms (protein, DNA, metal ions) that are in contact with the soaked INSTI molecules are invariant between HIV-1 and PFV (Hare et al., 2010a). Thus, we expect that structural differences between HIV-1 and PFV intasomes that are directly relevant to INSTI binding will be small. An unbiased test of this idea can be made by comparing the active sites in isolated catalytic core domains from ...
So you stop the drug, calculate the patients creatinine clearance and, knowing that it has first order elimination kinetics you can do the math. For more severe, life threatening bleeding (e.g. head bleeds) that is not enough. It is removed pretty well by hemodialysis. Although there is no specific antidote currently available there has been talk of using 4 factor PCC (not available in the US), 3 factor PCC supplemented with a little recombinant activated factor VII or factor VIII inhibitor bypassing activity. Those remedies are mentioned in the review. The evidence to support their use is slim but an algorithm is presented ...

Type and quantity of replacement treatment, together with haematological and immunological parameters were determined in 37 boys with severe haemophilia A and 41 children with other bleeding disorders. The quantity of factor VIII concentrate given to boys with severe haemophilia A (mean U/year) showed a significant inverse correlation with total white cell counts, lymphocyte counts, platelet counts, and the ratio of monoclonal antibody defined T lymphocyte subsets, T4 and T8 (T4:T8). Of the boys with severe haemophilia A, 49% had inversed T4:T8 ratios and 24% had thrombocytopenia. Treatment with high dose factor VIII concentrate (more than 25 000 U/year) was associated with low platelet counts, low lymphocyte counts, low T4:T8 ratios, and hypergammaglobulinaemia. In addition, six patients with severe haemophilia A and factor VIII inhibitors had inversed T4:T8 ratios. Patients treated exclusively with cryoprecipitate or prothrombin complex concentrates had normal T4:T8 ratios and platelet counts. ...
A carrier is a female who has the genetic mutation for hemophilia on one of her X chromosomes. Carriers with clotting factors levels of less than 50% of normal may have symptoms similar to a male with mild hemophilia. They are often called symptomatic carriers or are diagnosed with mild hemophilia. Approximately one-third of carriers experience bleeding symptoms. By definition, if a woman has clotting factor levels less than 50%, she has mild hemophilia.. Von Willebrand Disease (vWD), the most common inherited bleeding disorder in the US, and is a cause of heavy menstrual bleeding and other bleeding problems in women and adolescent girls. Women can also have other rare blood disorders like factor deficiencies I, II, V, VII, X, XI, XII, XIII and types of platelet disorders.. Bleeding disorders among females may cause special challenges because of the bleeding associated with menstruation and childbirth. Menorrhagia is abnormally heavy and prolonged menstrual period and is the most common symptom ...
In an article release by the CDC (Center for Disease Control and Prevention), research reports key findings related to the formation of inhibitors (antibodies) in patients who have hemophilia. The study shows that hemophilia A and hemophilia B patients who develop inhibitors are likely to have a specific type of antibody called immunoglobulin G subclass 4, or IgG4. In the event that traditional inhibitor tests do not provide clear results, testing for these antibodies instead may help clarify whether an inhibitor is present.. Inhibitors are antibodies (protein) that prevents or stops infused factor from working. For those with bleeding disorders like hemophilia A and hemophilia B, inhibitors often develop because the bodys immune system identifies the clotting factor as foreign. A blood test called Nijmegen-Bethesda Assay (NBA) is used to diagnose inhibitors.. For some cases, NBA can produce an unclear result as to whether a patient has an inhibitor or not. The CDC researchers have addressed ...
Coagulation Factor V is an essential component of the prothrombinase complex, which activates the zymogen prothrombin to thrombin. A patient was described who developed a Factor V inhibitor that neutralized the procoagulant activity of Factor V and resulted in a fatal hemorrhagic diathesis (Coots, M. C., A. F. Muhleman, and H. I. Glueck. 1978. Am. J. Hematol. 4:193-206). This inhibitor was shown to be an IgG antibody that bound to the light chain of Factor V. Using a series of light chain deletion mutants, we have found that this antibody binds to the second C-type domain of the light chain. Both inhibitor IgG and Fab fragments rapidly neutralized the procoagulant activity of Factor Va, implying that the neutralization resulted from specific binding to the C2 domain. We have previously demonstrated that deletion of the C2 domain results in loss of procoagulant activity, as well as loss of phosphatidylserine-specific binding. Confirming these results, both inhibitor IgG and Fab fragments ...

WEDNESDAY, Sept. 9, 2020 (HealthDay News) -- Researchers may have found a way for people with severe hemophilia to take their standard treatment less often, if the results of an early trial pan out.. In what experts called a feat of bioengineering, scientists were able to create a fusion protein that may extend the interval between treatments for hemophilia -- from about every couple of days to once a week.. The early findings are based on a one-time treatment given to 16 patients.. But researchers were hopeful a larger, ongoing trial will prove the approach effective.. Hemophilia is a bleeding disorder caused by a genetic mutation. In the most common form -- hemophilia A -- people lack a properly functioning factor VIII, a protein that helps blood clot. Some people have relatively mild hemophilia -- with excessive bleeding if they sustain a cut, for example. Others have frequent spontaneous bleeding episodes into their joints and muscles.. When hemophilia is that severe, it requires regular ...
|jats:p|Histone lysine demethylase (KDMs) are involved in the dynamic regulation of gene expression and they play a critical role in several biological processes. Achieving selectivity over the different KDMs has been a major challenge for KDM inhibitor development. Here we report potent and selective KDM5 covalent inhibitors designed to target cysteine residues only present in the KDM5 sub-family. The covalent binding to the targeted proteins was confirmed by MS and time-dependent inhibition. Additional competition assays show that compounds were non 2-OG competitive. Target engagement and ChIP-seq analysis showed that the compounds inhibited the KDM5 members in cells at nano- to micromolar levels and induce a global increase of the H3K4me3 mark at transcriptional start sites.|/jats:p|

WHAT IS HEMOPHILIA?. Hemophilia is a rare bleeding disorder in which the blood doesnt clot normally.. After an injury, people with hemophilia do not bleed more or faster than people without hemophilia, but they do bleed longer. They also may bleed internally especially in the knees, ankles and elbows. This bleeding can cause damage to organs and tissues and may become life threatening.. Hemophilia is usually inherited and caused by the absence or inactivity of clotting factor. Clotting factor is a protein needed for normal blood clotting. There are several types of clotting factors, and they work with platelets to help form a clot. Platelets are small blood cell fragments that are formed in the bone marrow and play a major role in blood clotting. When blood vessels are injured, clotting factors help the platelets stick together to plug cuts and breaks to stop the bleeding. Without clotting factors, normal blood clotting cant take place.. There are two main types of hemophilia: A and B. If you ...
