distinguished by a 9 aa deletion in the extracellular juxtamembrane region. These receptors bind the vitamin K-dependent protein growth arrest specific gene 6 (Gas6) which is structurally related to the anticoagulation factor Protein S. Binding of Gas6 induces receptor autophosphorylation and downstream...

The APC anticoagulation system is unique in the sense that its anticoagulant function is activated only when thrombin is formed by the coagulation system, and thus APC activity is regulated proportionately by procoagulant activity [1,2].Hamasaki,N....
1.Question: In cell involving G-proteins, the signal can be terminated by desensitization mechanisms. How is both the canonical and noncanonical Wnt signal eventually terminated/desensitized? We also discussed the noncanonical Wnt signaling pathway (independent of B-catenin induced transcriptional activity...
In addition to these procoagulant activities, thrombin plays a crucial role in downregulating its own formation by activation of the protein C anticoagulation pathway.6 When bound to its cofactor thrombomodulin (TM), thrombin efficiently cleaves protein C to activated protein C (APC), a powerful ...
For the previous two months she had been forced to discontinue her usual warfarin because of extreme over anticoagulation and extensive ecchymoses. Otherwise she felt well and was working full time. When she presented to us, the following laboratory data were obtained: pro time 18.7s, aPTT ...
In AAV-APC treated mice we observed dose dependent anticoagulation: 8 thrombi /12 injury sites in mice expressing ~80 ng/ml, 3/10 at ~160 ng, and 1/7 at ~260 ng/ml APC compared to 42/42 in untreated controls (P<0.001-0.0001). Expression of PC resulted in prevention of thrombus ...

A group of patients with APC resistance and additional underlying conditions, such as oral contraception, oral anticoagulation, pregnancy and recurrent thrombosis showed pathologically low protein S values with activity assays as well as with free antigen assays. To differentiate between the effects of ...
