The aberrant protein crosslinks formation during lung injury as results total body irradiation (TBI) and bone marrow transplantation (BMT) therapy has been examined as apossible contributory factor in organ or tissue pathogenesis. Female C3HeB/ FeJ mice were used for an experimental animal. Carbon monoxide uptake (V(CO)) was measured at 1, 2, 3, 4 and 5 months after TBI at respective doses of 12, 14, 16 and 18 Gy 16 h prior to syngeneic BMT. Also as a measure of aberrant protein crosslinking in the inured tissues, transglutaminase (TGase)-activities and crosslinked protein were examined along with thrombin, a protease known to activate TGases. Reductions of VCO were detected following TBI and BMT. Activities of thrombin and TGase 1, and crosslinked protein in bronchoalveolar lavage (BAL) fluid of the mice 1 wk after TBI at 12 Gy and BMT were identified and found to be elevated in the treated animals. These findings suggest that elevated levels of crosslinked proteins and TGase I in the bronchoalveolar larvage during the lung injury could have enhanced the organ pathogenesis following TBI and BMT.

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 METHODS: Twenty-eight NSCLC patients and 28 normal controls who had been individually age-, gender-, body mass index-, smoking status-, and smoking amount-matched were enrolled: 13 adenocarcinomas, 11 squamous cell carcinomas, and four undifferentiated NSCLCs; four stage I, two stage II, 12 stage III, and 10 stage IV NSCLCs. FXIII activity was measured using fluorescence-based protein arrays. RESULTS: The median FXIII activity level of the NSCLC group [24.2 Loewy U/mL, interquartile range (IQR) 14.9-40.4 Loewy U/mL] was significantly higher than that of the healthy group (17.5 Loewy U/mL, IQR 12.6-26.4 Loewy U/mL) (p=0.01). There were no differences in FXIII activity between adenocarcinoma (median 18.6 Loewy U/mL) and squamous cell carcinoma (median 28.7 Loewy U/mL). NSCLC stage significantly influenced FXIII activity (p=0.02). The FXIII activity of patients with stage III NSCLC (median 27.3 Loewy U/mL, IQR 19.3-40.5 Loewy U/mL) was significantly higher than those of patients with stage I or II (median 14.0 Loewy U/mL, IQR 13.1-23.1 Loewy U/mL, p=0.04). FXIII activity was negatively correlated with aPTT in NSCLC patients (r=-0.38, p=0.04). CONCLUSION: Patients with advanced-stage NSCLC exhibited higher coagulation FXIII activity than healthy controls and early-stage NSCLC patients.

3.Advances of Coagulation Factor XIII.
Chinese Medical Journal 2017;130(2):219-223
OBJECTIVETo provide a comprehensive literature review on roles of coagulation factor XIII (FXIII) in coagulation, wound healing, neoplasm, bone metabolism, and pregnancy.
DATA SOURCESAll 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 publications before 2000 were also included.
STUDY SELECTIONWe reviewed the role of FXIII in biologic processes as documented in clinical, animal, and in vitro studies.
RESULTSFXIII, a member of the transglutaminase (TG) family, plays key roles in various biological processes. Besides its well-known function in coagulation, the cross-linking of small molecules catalyzed by FXIII has been found in studies to help promote wound healing, improve bone metabolism, and prevent miscarriages. The study has also shown that FXIII concentration level differs in the blood of patients with leukemia and solid tumors and offers promises as a diagnostic indicator.
CONCLUSIONSFXIII has many more biologic functions besides being known as coagulation factor. The TG activity of FXIII contributes to several processes, including wound healing, bone extracellular matrix stabilization, and the interaction between embryo and decidua of uterus. Further research is needed to elucidate the link between FXIII and leukemia and solid tumors.

OBJECTIVETo observe the clinical significance of postoperative personalized antithrombotic therapy for patients with hemophilic arthritis (HA) patients after arthroplasty.
METHODSFrom September 2005 to October 2013, 11 cases of arthroplasty for hemophilic arthritis in hip and knee total operation 14 times,including 1 case of double knees (calculated as one operation), operation in left knees 6 times, operation in right knees 5 times, 2 in hip. All the patients were male and the age ranged from 23 to 57 years old,with an average of (36.1 ± 11.0) years old; the average weight was (64.1 ± 8.9) kg. All the patients were preoperatively diagnosed and classified as hemophilic arthritis with the radiological images and laboratory tests. According to the function of joints, the risk of postoperative venous thromboembolism (VTE), and dynamic observation of Factor VIII:C (FVIII:C) activity, patients were treated with personalized antithrombus by adjusting the dosage of recombinant human coagulation factor VIII (Kogenate FS). All the patients were orderly divided into postoperatively distal joints moving group and none-moving group to observe the coagulation function.
RESULTSThe enrolled patients had no postoperative complication of VTE and pulmonary embolism (PE). The APTT and D-2 were different between two groups in the postoperative early stage. Length of hospital day was shorter in the moving group than none-moving group.
CONCLUSIONBecause of the self-coagulation disorder, patients with HA tended to bleed. However it doesn't mean that there is no risk of postoperative thrombosis. Therefore,it's important to determine how to control the balance between postoperative antithrombus, hemostasis,and coagulation factor replacement therapy after arthroplasty for HA. Postoperative moving has proved helpful for HA, especially in reducing the risk of hemostasis and shortening the time in hospital.

Change in fibrin stabilizing activity of factor XIII A subunit (FXIII-A) caused by a specific mutation, Val34Leu, is recently implicated to incidences of pathophysiology of thrombosis. In an effort to understand the effect of Val34Leu on enhanced catalytic role of FXIII-A, wild type human factor XIII A (HFXIII-A) and mutant HFXIII-A: HFXIII-A (V34L), HFXIII-A (V35L) and HFXIII-A (V34L/V35L) cDNA were expressed in E.coli system where the purified recombinant FXIII-A (rFXIII-A) showed a similar specific transglutaminase activity comparable to the human native FXIII-A from platelet. Using these rFXIII-A mutants, the activation kinetics by thrombin and the enzymatic properties of the activated rFXIII-A were characterized. rFXIII-A (V34L) and rFXIII-A (V34L/V35L) mutants were activated by thrombin much faster than those of wild type rFXIII-A and V35L variant. However, the activated rFXIII-A and mutants showed the identical catalytic efficiency as measured by in vitro assay. These results suggest that ready activation caused by a specific mutation of neighboring thrombin cleavage site(s) in the activation peptide of FXIII-A like V34L resulted in the real-time amount of the activated factor XIII-A that could influence the outcome of fibrin stabilization in vivo such as alpha2- plasmin inhibitor crosslinking to fibrin, a reaction known to be dependent on the initial concentration of active factor-XIII-A.

AIMTo study the effect of recombinant hirudin (rH) on tPA-induced fibrinolysis and the possible mechanism of its action.
METHODSThe effect of rH on thrombin-fibrin complex (Th-Fn) was detected by 99mTc labeled rH. In the in vitro clot lysis, tPA as plasminogen activator, and recalcified plasma as plasminogen resource were used to study the influence of rH on fibrinolysis by detecting TAFIa, D-Dimer and FXIII.
RESULTSIn a canine model of femoral artery thrombosis, a clear radioactivity strip was imaged in 30 - 60 min on a part image, and the femoral vein thrombosis developed at 30 min. rH efficiently inhibited clot regeneration. Addition of TM could inhibit clot lysis obviously, and CPI could shorten the delay of clot lysis which due to TAFIa. There was a dose-dependent relationship with TM concentration and TAFI activation. FXIII activation was inhibited by low concentration of rH ( < or = 0.2 u x mL(-1)), and the level of fibrinolysis product, D-Dimer, increased.
CONCLUSIONrH could inhibit the thrombin binding to fibrin. rH inhibited the activation of TAFI and FXIII by combining with thrombin which resulted in enhancement of thrombolysis.
