OBJECTIVE To provide a comprehensive literature review on roles of coagulation factor XIII (FXIII) in coagulation, wound healing, neoplasm, bone metabolism, and pregnancy. DATA SOURCES All articles in PubMed with key words "Coagulation factor XIII", "wound", "leukemia", "tumor", "bone," and "pregnancy" with published date from 2001 to 2016 were included in the study. Frequently cited publicat...

BACKGROUND AND OBJECTIVE Recent studies have suggested an association between a genetic variation in the coagulation factor XIII (FXIII Val34Leu) and decreased risk of vascular thrombosis. DESIGN AND METHODS We investigated the frequency of the FXIII Val34Leu polymorphism in 150 consecutive, unrelated and relatively young (<55 years) survivors of myocardial infarction (MI) with angiographical...

Zinc released from activated platelets binds fibrin(ogen) and attenuates fibrinolysis. Although zinc also affects clot formation, the mechanism and consequences are poorly understood. To address these gaps, the effect of zinc on clot formation and structure was examined in the absence or presence of factor (F) XIII. Zinc accelerated a) plasma clotting by 1.4-fold, b) fibrinogen clotting by 3.5-...

The plasma transglutaminase, factor XIIIa (FXIIIa), circulates as a zymogen containing two proteins, A and B, arranged in a noncovalent tetrameric complex, A2B2. Biosynthesis of plasma FXIII has not previously been demonstrated. In the present study, direct evidence has been obtained that two human hepatoma cell lines, Hep G2 and PLC/PRF/5, synthesize and secrete FXIII B protein. Secretion of t...

Factor XIII on activation by thrombin cross-links fibrin. A common polymorphism Val to Leu at position 34 in the FXIII A subunit is under investigation as a risk determinant of thrombosis. Because Val34Leu is close to the thrombin cleavage site, the hypothesis that it would alter the function of FXIII was tested. Analysis of FXIII subunit proteolysis by thrombin using sodium dodecyl sulfate-pol...

OBJECTIVE Factor XIII (FXIII) cross-links fibrin upon activation by thrombin. Activation involves cleavage at residue 37 by thrombin, releasing an activation peptide. A common polymorphism (valine to leucine variant at residue 34, V34L), located in the activation peptide, has been associated with increased activation rates and paradoxically a protective effect in cardiovascular disease. There i...

Inherited deficiency of factor XIIIA subunit (FXIIIA) is an autosomal recessive disorder that is characterized by a life-long bleeding tendency and complications in wound healing. Molecular genetic studies have shown the deficiency can be due to small sequence changes within the FXIIIA gene, such as point mutations or microdeletions. On molecular analysis of the FXIIIA gene in an FXIII-deficien...

PURPOSE Factor XIII (FXIII), a thrombin-activated plasma transglutaminase zymogen, is involved in cancer development and progression through a triggered coagulation pathway. The aim of this study was to examine whether FXIII activity levels differed in non-small cell lung cancer (NSCLC) patients according to histological types and TNM stage when compared with healthy subjects. MATERIALS AND M...

The role of factor XIII subunit A (FXIII-A) is not restricted to hemostasis. FXIII-A is also present intracellularly in several human cells and serves as a diagnostic marker in a wide range of dermatological diseases from inflammatory conditions to malignancies. In this review, we provide a guide on the still controversial interpretation of dermal cell types expressing FXIII-A and assess the pr...

The activation and regulation of coagulation Factor XIII (FXIII) protein has been the subject of active research for the past three decades. Although discrete evidence exists on various aspects of FXIII activation and regulation a combinatorial structure/functional view in this regard is lacking. In this study, we present results of a structure/function study of the functional chain of events f...
