Abstract
Limited proteolysis is a pivotal mechanism regulating protein functions. Identifying physiologically or pathophysiologically relevant cleavage sites helps to develop molecular tools that can be used for diagnostics or therapeutics. During proteolysis of secretory and membrane proteins, part of the cleaved protein is liberated and destined to undergo degradation but should retain original cleavage sites created by proteolytic enzymes. We profiled endogenous peptides accumulated for 4 h in media conditioned by primary cultured rat cardiac fibroblasts. A total of 3916 redundant peptide sequences from 94 secretory proteins and membrane proteins served to identify limited cleavage sites, both annotated and unannotated, for signal peptide or propeptide removal, peptide hormone processing, ectodomain shedding, and regulated intramembrane proteolysis. Incorrectly predicted signal cleavage sites are found in typical proteins such as extracellular matrix proteins and the peptide hormone precursor adrenomedullin ADM. The revealed signal peptide cleavage site for ADM was experimentally verified by identifying the major molecular form of flanking proadrenomedullin N-terminal peptide. We suggest that profiling of endogenous peptides, like transcriptome sequence reads, makes sense in regular cells such as fibroblasts and that peptidomics provides insight into proteolysis-regulated protein functions.

Abstract
The composition of the intestinal microbiota of 92 healthy Japanese men was measured following consumption of identical meals for 3 days; terminal restriction fragment length polymorphisms were then used to analyse the DNA content of their faeces. The obtained operational taxonomic units (OTUs) were further analysed using seven restriction enzymes: 516f-BslI and -HaeIII, 27f-MspI and -AluI, and 35f-HhaI, -MspI and -AluI. Subjects were classified by their body mass index (BMI) as lean (<18.5) or obese (>25.0). OTUs were then analysed using data mining software. Pearson correlation coefficients on data mining results indicated only a weak relationship between BMI and OTU diversity. Specific OTUs attributed to lean and obese subjects were further examined by data mining with six groups of enzymes and closely related accession numbers for lean and obese subjects were successfully narrowed down. 16S rRNA sequences showed Bacillus spp., Erysipelothrix spp. and Holdemania spp. to be present among 30 bacterial candidates related to the lean group. Fifteen candidates were classified Firmicutes, one was classified as Chloroflexi, and the others were not classified. 45 Microbacteriaceae, 11 uncultured Actinobacterium, and 3 other families were present among the 119 candidate OTUs related to obesity. We conclude that the presence of Firmicutes and Actinobacteria may be related to the BMI of the subject.

Abstract
BACKGROUND Autoimmune hemophilia-like disease (hemorrha-philia or hemorrhagic disorder) caused by anti-factor XIII antibodies (termed AH13) or 'autoimmune FXIII deficiency' is a life-threatening bleeding disorder. AH13 was thought to be rare worldwide. OBJECTIVES Because the number of diagnosed AH13 cases has recently been increasing, at least in Japan, we conducted a nationwide survey supported by the Japanese Ministry of Health, Labor, and Welfare, and explored the pathologic mechanism(s) of AH13. METHODS We diagnosed AH13 cases during the last 11 years according to the presence of anti-FXIII autoantibodies confirmed by a dot blot assay and ELISA, and characterized 33 of these both immunologically and biochemically. RESULTS The AH13 cases were immunologically classified into three types, Aa, Ab, and B. Type Aa autoantibodies, observed in 27 cases, were directed against the native FXIII A subunit (FXIII-A), and blocked FXIII activation. The autoantibodies not only prevented assembly of new FXIII-A2 B2 heterotetramers, but also removed FXIII-A from native FXIII-A2 B2 heterotetramers by forming an FXIII-A-IgG complex. Type Ab autoantibodies, detected in three cases, preferentially bound to activated FXIII-A and inhibited its activity. Type Aa and Ab autoantibodies were 'neutralizing' FXIII antibodies (or FXIII inhibitors), and thus could be screened with functional assays. Type B antibodies, detected in two cases, were non-neutralizing anti-FXIII B subunit (FXIII-B) autoantibodies that possibly accelerated the clearance of FXIII, and thus could be diagnosed exclusively with immunologic methods. CONCLUSION There are three major types of anti-FXIII autoantibody, with distinct targets and mechanisms that cause AH13.

Abstract
Covalent cross-linking of fibrin chains is required for stable blood clot formation, which is catalyzed by coagulation factor XIII (FXIII), a proenzyme of plasma transglutaminase consisting of catalytic A (FXIII-A) and non-catalytic B subunits (FXIII-B). Herein, we demonstrate that FXIII-B accelerates fibrin cross-linking. Depletion of FXIII-B from normal plasma supplemented with a physiological level of recombinant FXIII-A resulted in delayed fibrin cross-linking, reduced incorporation of FXIII-A into fibrin clots, and impaired activation peptide cleavage by thrombin; the addition of recombinant FXIII-B restored normal fibrin cross-linking, FXIII-A incorporation into fibrin clots, and activation peptide cleavage by thrombin. Immunoprecipitation with an anti-fibrinogen antibody revealed an interaction between the FXIII heterotetramer and fibrinogen mediated by FXIII-B and not FXIII-A. FXIII-B probably binds the γ-chain of fibrinogen with its D-domain, which is near the fibrin polymerization pockets, and dissociates from fibrin during or after cross-linking between γ-chains. Thus, FXIII-B plays important roles in the formation of a ternary complex between proenzyme FXIII, prosubstrate fibrinogen, and activator thrombin. Accordingly, congenital or acquired FXIII-B deficiency may result in increased bleeding tendency through impaired fibrin stabilization due to decreased FXIII-A activation by thrombin and secondary FXIII-A deficiency arising from enhanced circulatory clearance.

Abstract
A 65-year-old woman was admitted with acute intramuscular hemorrhage of the left gluteus medius and piriformis muscles and associated anemia. Blood tests showed low plasma factor XIII (FXIII) antigen and activity. A cross-mixing test revealed a concave "inhibitor" pattern and anti-FXIII-A subunit antibody was detected. The patient was diagnosed with autoimmune hemorrhaphilia resulting from anti-FXIII antibody. The bleeding has not recurred since the initiation of treatment with oral immunosuppressive agents. Although hemorrhagic acquired FXIII deficiency is a rare disorder, prompt recognition of the underlying mechanism can save lives.

Abstract
Coagulation factors play essential roles in not only hemostasis but also thrombosis. The coagulation reaction consists of a stepwise sequence of proteolytic reactions of the coagulation factors, and is generally divided into two pathways, a tissue factor(TF)-dependent "extrinsic pathway" and a contact factor-dependent "intrinsic pathway". The extrinsic pathway is responsible for the initiation of the clotting reaction, while the intrinsic pathway most likely amplifies it. Elevated levels of various coagulation factors such as TF, factor VIII and prothrombin have been linked to an increased thrombotic risk. To prevent thrombus formation, endothelial cells express several receptors and activators for anticoagulant factors such as antithrombin, TF-pathway inhibitor, protein C and protein S. Defects in this anticoagulant system also increase the risk of thrombosis.

Abstract
Low-density lipoprotein apheresis (LDL-A) treatment has been shown to decrease serum LDL cholesterol levels and prevent cardiovascular events in homozygous patients with familial hypercholesterolemia. Recently, LDL-A treatment has been suggested to have beneficial effects beyond the removal of LDL particles. In this study, to clarify the preventive effects of LDL-A treatment on atherosclerosis, the waste fluid from the adsorption columns was analyzed. The waste fluid of LDL adsorption columns was analyzed by two-dimensional electrophoresis followed by mass spectrometry. Serum concentrations of the newly identified proteins before and after LDL-A treatment were measured by enzyme-linked immunosorbent assay. We identified 48 kinds of proteins in the waste fluid of LDL adsorption columns, including coagulation factors, thrombogenic factors, complement factors, inflammatory factors and adhesion molecules. In addition to the proteins that were reported to be removed by LDL-A treatment, we newly identified several proteins that have some significant roles in the development of atherosclerosis, including vitronectin and apolipoprotein C-III (Apo C-III). The serum levels of vitronectin and Apo C-III decreased by 82.4% and 54.8%, respectively, after a single LDL-A treatment. While Apo C-III was removed with very low-density lipoprotein (VLDL) and LDL, vitronectin was removed without association with lipoproteins. The removal of proteins observed in the waste fluid has a certain impact on their serum levels, and this may be related to the efficacy of LDL-A treatment. Proteomic analysis of the waste fluid of LDL adsorption columns may provide a rational means of assessing the effects of LDL-A treatment.

Abstract
Mass spectrometry-based unbiased analysis of the full complement of secretory peptides is expected to facilitate the identification of unknown biologically active peptides. However, tandem MS sequencing of endogenous peptides in their native form has proven difficult because they show size heterogeneity and contain multiple internal basic residues, the characteristics not found in peptide fragments produced by in vitro digestion. Endogenous peptides remain largely unexplored by electron transfer dissociation (ETD), despite its widespread use in bottom-up proteomics. We used ETD, in comparison to collision induced dissociation (CID), to identify endogenous peptides derived from secretory granules of a human endocrine cell line. For mass accuracy, both MS and tandem MS were analyzed on an Orbitrap. CID and ETD, performed in different LC-MS runs, resulted in the identification of 795 and 569 unique peptides (ranging from 1000 to 15000 Da), respectively, with an overlap of 397. Peptides larger than 3000 Da accounted for 54% in CID and 46% in ETD identifications. Although numerically outperformed by CID, ETD provided more extensive fragmentation, leading to the identification of peptides that are not reached by CID. This advantage was demonstrated in identifying a new antimicrobial peptide from neurosecretory protein VGF (non-acronymic), VGF[554-577]-NH2, or in differentiating nearly isobaric peptides (mass difference less than 2 ppm) that arise from alternatively spliced exons of the gastrin-releasing peptide gene. CID and ETD complemented each other to add to our knowledge of the proteolytic processing sites of proteins implicated in the regulated secretory pathway. An advantage of the use of both fragmentation methods was also noted in localization of phosphorylation sites. These findings point to the utility of ETD mass spectrometry in the global study of endogenous peptides, or peptidomics.

Abstract
Computed tomography (CT) was performed on 400 claws (200 inner and 200 outer claws) of 100 pairs of bovine hind limbs to investigate the etiological theory that an exacerbating factor for ulceration is exostosis of the tuberculum flexorium within the distal phalanx. A variety of morphological changes of the tuberculum flexorium of bovine hind limb claws was visualized by 3-dimensional CT, and the geometry of these claws suggested a growth pattern of bone development with respect to the assumed daily loading patterns. This growth occurs initially at the abaxial caudal aspect of the distal phalanx and is followed by horizontal progression toward the axial aspect. The length of downward bone development on the solar face of the distal phalanx was 2.73±1.32 mm in the outer claws, significantly greater than in the inner claws (2.38±0.96 mm). Ratios of downward (vertical) bone development to the thickness of the subcutis and the corium (VerBD ratios) did not differ between the outer and inner claws (36.7 vs. 38.3%, respectively). Ratios of horizontal bone development to the axial-to-abaxial line of the tuberculum flexorium (HorBD ratios) were approximately 60% for both outer and inner claws. These quantitative measures regarding horizontal and vertical bone development within the distal phalanx were positively correlated with age and VerBD ratios (r=0.53 and r=0.36 for the inner and outer claws, respectively). Correlations between claw width of the outer claw and length of vertical bone development (r=0.43), the HorBD ratio (r=0.51), and the VerBD ratio (r=0.42) suggested that the relative size difference between the inner and outer claws enhances bone development in the outer claw. Correlation coefficients between VerBD and HorBD ratios (r=0.52 and 0.63 for the inner and outer claws, respectively) suggested that horizontal and vertical bone development occurs as a synchronized process within the tuberculum flexorium. This age-related progress of bone development within the tuberculum flexorium is associated with increased exposure to several exacerbating factors and the laminitic process.

Abstract
Antimicrobial peptides (AMPs) are effector molecules that are able to kill or inactivate microbial pathogens. However, most AMPs harbor multiple basic amino acids that hamper current proteomic identification. In our peptidomic survey of endogenous peptides, we identified a novel intramolecular disulfide-linked 22-residue amidated peptide. This peptide, designated AMP-IBP5 (antimicrobial peptide derived from insulin-like growth factor-binding protein 5), showed antimicrobial activity against six of the eight microorganisms tested at concentrations comparable to or lower than those for well-characterized AMPs cathelicidin and β-defensin-2. AMP-IBP5 is identical at the amino acid level between human, mouse, rat, pig, and cow. Natural occurrence of this peptide as the originally isolated form was demonstrated in the rat brain and intestine, using mass spectrometric characterization of major immunoreactivity. The peptide is flanked N-terminally by a single arginine and C-terminally by a common amidation signal, indicating that insulin-like growth factor-binding protein 5 (IGFBP-5) undergoes specific cleavage by a defined set of processing proteases. Furthermore, the intramolecular linkage C199-C210 reveals itself as a correct disulfide pairing in the precursor protein, the finding not inferred from closely related family members IGFBP-4 and -6. In principle, neither conventional proteomics nor bioinformatics would achieve the identification of this AMP. Our study exemplifies the impact of peptidomics to study naturally occurring peptides.

Abstract
BACKGROUND Contrast-enhanced ultrasonography with perflubutane microbubbles improves the diagnostic accuracy to differentiate benign and malignant focal liver lesions in dogs. HYPOTHESIS Perflubutane microbubbles-enhanced ultrasonography is useful for differentiation of benign from malignant focal splenic lesions in dogs. ANIMALS Twenty-nine clinical dogs with single or multiple focal splenic lesions detected by conventional ultrasonography. METHODS Prospective clinical observational study. Perflubutane microbubbles-enhanced ultrasonography was performed in 29 dogs with focal splenic lesions. Qualitative assessment of the enhancement pattern was performed in the early vascular, late vascular, and parenchymal phases. RESULTS In the early vascular phase, a hypoechoic pattern was significantly associated with malignancy (P=.02) with sensitivity of 38% (95% confidence interval [CI], 25-38%) and specificity of 100% (95% CI, 84-100%). In the late vascular phase, a hypoechoic pattern was significantly associated with malignancy (P=.001) with sensitivity of 81% (95% CI, 66-90%) and specificity of 85% (95% CI, 65-95%). There was no significant difference between malignant and benign lesions during the parenchymal phase. CONCLUSIONS AND CLINICAL IMPORTANCE Hypoechoic splenic nodules in the early and late vascular phases with perflubutane microbubbles-enhanced ultrasonography are strongly suggestive of malignancy in dogs.

Abstract
This review focuses on the evolutionary and functional relationship of calcitonin receptor-stimulating peptide (CRSP) with calcitonin (CT)/calcitonin gene-related peptide (CGRP) in mammals. CRSP shows high sequence identity with CGRP, but distinct biological properties. CRSP genes (CRSPs) have been identified in mammals such as pigs and dogs of the Laurasiatheria, but not in primates and rodents of the Euarchontoglires or in non-placental mammals. CRSPs have genomic organizations highly similar to those of CT/CGRP genes (CT/CGRPs), which are located along with CGRPs in a locus between CYP2R1 and INSC, while the other members of the CGRP superfamily, adrenomedullin and amylin, show genomic organizations and locations distinct from CT, CGRP, and CRSP. Thus, we categorized these three peptides into the CT/CGRP/CRSP family. Non-placental mammals having one and placental mammals having multiple CT/CGRP/CRSP family genes suggests that multiplicity of CT/CGRP started at an early stage of mammalian evolution. In the placental mammals, Laurasiatheria generally possesses multiple CRSPs and only one CT/CGRP, while Euarchontoglires possesses CT/CGRP and CGRPbeta but no CRSP, indicating an increase in the diversity and multiplicity of this family of genes in mammalian evolution. Phylogenetic analysis suggests that some CRSPs have been generated very recently in mammalian evolution. Taken together, the increase in the number and complexity of the CT/CGRP/CRSP family genes may have due to evolutionary pressure to facilitate adaptation during mammalian evolution. In this regard, it is important to elucidate the physiological roles of CT, CGRP and CRSP from the viewpoint of the CT/CGRP/CRSP family even in Euarchontoglires.

Abstract
OBJECTIVE Atrial and brain natriuretic peptides (ANP and BNP, respectively) function via guanylyl cyclase (GC)-A, resulting in diuresis, natriuresis, and blood vessel dilation. Here, we investigated the role of endogenous ANP/BNP-GC-A signaling on reparative vascular remodeling using a hind-limb ischemia model. METHODS AND RESULTS In GC-A-deficient mice (GC-A-KO), hind-limb ischemia resulted in autoamputation or severe ulcers in 60% of mice (6/10) during the 28-day observation period. In wild-type (WT) mice, partial amputation or mild ulcers were detected in only 20% of mice (2/10). Laser Doppler perfusion imaging revealed that the recovery of blood flow in the ischemic limb was significantly inhibited in GC-A-KO mice compared with WT mice. Immunostainings with anti-PECAM-1 antibody demonstrated that, in GC-A-KO, the capillary density of the ischemic tissue was significantly diminished compared to WT. Furthermore, bone marrow transplantation showed the predominant role of GC-A on local ischemic tissue rather than on vascular progenitor cells mobilized from bone marrow during vascular remodeling. In cultured human endothelial cells, ANP treatment significantly stimulated mRNA expressions of vascular endothelial growth factor and endothelial nitric oxide synthase via Erk1/2-dependent mechanism. CONCLUSIONS These results suggest that endogenous ANP and BNP play important roles in reparative vascular remodeling in ischemic tissue.

Abstract
The aim of our study was to investigate the role of nerve growth factor (NGF) on the expression of the p73 protein in human ependymoblastoma (EP) and medulloblastoma (MB) cells. It was found that NGF exposure on MB cells blocks proliferation, as well as on EP cells and induces overexpression of p73. NGF reduces the number of cells and promotes the expression of TrkA of these neoplastic cells. Moreover, NGF plus cisplatin treatment reduces the cytotoxic effect of cisplatin. These observations indicate that NGF by interfering with mechanisms associated with cells proliferation and survival might induce the differentiation event through TrkA pathways.

Abstract
7562 Background: Carboplatin plus paclitaxel and carboplatin plus gemcitabine chemotherapy have shown a good response and an improved survival against advanced NSCLC. This phase II trial assessed the feasibility, safety and efficacy of a bi-weekly schedule for adjuvant chemotherapy. Methods: Patients with completely resected stage IB-IIIB NSCLC were randomized to either carboplatin (AUC3) plus paclitaxel (90mg/m2) (arm A) or carboplatin (AUC3) plus gemcitabine (1000 mg/m2) (arm B), q2w for 8 cycles within 8 weeks after surgery. The main inclusion criteria were no prior chemotherapy or radiotherapy, ECOG PS 0–1, an age of less than 80 years, and an adequate organ function. The primary endpoint was compliance, and secondary endpoints were the disease free survival (DFS) and toxicity. The patients were stratified by gender, histology (adenoca vs. non-adenoca) and disease stage. Results: Between 07/2005 and 06/2007, 76 patients were randomized and 75 were eligible (including 48 males, 27 females; median age 66 years) for intent-to-treat analysis (39 in arm A, 36 in arm B). The histologic types included adenocarcinoma (n=51), squamous cell carcinoma (n=18), large cell carcinoma (n=5), and adenosquamous cell carcinoma (n=1). The pathological stages were IB/IIA/IIB/IIIA/IIIB: 22/10/13/29/1. Twenty-one of 39 pts (54%) in arm A and 25 of 36 pts (69%) in arm B completed 8 cycles, and 59% in arm A and 81% in arm B completed ≥6 cycles. Grade 3/4 hematologic toxicities (%) in arms A/B were respectively; neutropenia 36/53, anemia 0/17, thrombocytopenia 3/0, nausea 3/3. No treatment related deaths were observed. Up to 12/2008, 11 of 39 pts in arm A and 13 of 36 pts in arm B had recurrent disease, but no significant difference was observed. Conclusions: This adjuvant bi- weekly scheduled chemotherapy in both arms resulted in a good compliance and feasible with acceptable levels of toxicity in completely resected NSCLC. No significant financial relationships to disclose.

Abstract
AIMS We examined whether the presence of Helicobacter is related to that of Acanthamoeba in river and soil environments. METHODS AND RESULTS The samples (river n = 51, soil n = 75) were collected in Sapporo City, Japan. PCR with primers for Helicobacter genus-specific and standard culture techniques were used to detect helicobacter. Prevalence of acanthamoeba was also evaluated by genus-specific PCR. The prevalence of Helicobacter genus-specific DNA in river water samples and in soil samples was 88% and 0%, respectively. No successful culture of helicobacter was achieved. The prevalence of Acanthamoeba genus-specific DNA in river samples and in soil samples was 61% and 96%, respectively. No statistical correlation between the prevalence of helicobacter and either that of acanthamoeba or water quality parameters (pH, turbidity and coliform group) except for temperature was found. CONCLUSIONS We revealed the presence of helicobacter in river water and non-existence of helicobacter in soil. However, the distribution of helicobacter did not overlap with that of acanthamoeba in rivers. SIGNIFICANCE FOR IMPACT OF THE STUDY: The role of acanthamoeba on the survival of helicobacter might be limited as the both are coincidentally present in the environment.

Abstract
Although malignant diseases are known to be associated with immune suppression, detailed mechanisms of this phenomenon are still unknown. NKG2D is an activating cell surface receptor expressed by natural killer (NK) cells and CD8+ T cells, and it has been reported that NKG2D engagement is extremely important for T cell activation. In the current study, NKG2D expression on CD8+ T cells and the frequency of CD4+ CD25+ regulatory T (Treg) cells were determined by multicolor flow cytometry to investigate one of the mechanisms responsible for immune evasion in esophageal cancer patients. NKG2D expression on CD8+ T lymphocytes in esophageal cancer patients was significantly lower than in those of normal controls. NKG2D expression in T3/T4 esophageal cancer was significantly lower than that in T1/T2 esophageal cancer. CD8+ T cells from patients with lymph node metastasis expressed significantly lower NKG2D than those without lymph node metastasis. Moreover, significantly lower NKG2D expression was observed in stage III/IV cancer in comparison with stage I/II. The frequency of CD4+CD25+ Treg cells in esophageal cancer patients was significantly higher than those in normal controls. NKG2D expression on CD8+ T cells was significantly inversely correlated with the frequency of CD4+CD25+ Treg cells in esophageal cancer patients. Our data indicates that decreased NKG2D expression on CD8+ T cells is correlated with disease severity. Decreased NKG2D expression and an increase in Treg cells may be one of the key mechanisms responsible for immune evasion in esophageal cancer.

Abstract
Calcitonin receptor-stimulating peptides (CRSPs) are new members of the calcitonin/calcitonin gene-related peptide (CT/CGRP) family identified in pigs, dogs and other domestic animals, and CRSP-1 is an active ligand for the CT receptor (CT-R). We recently sequenced porcine CRSP genes (Crsps) and found similarity with the CT/CGRP gene (Ct/Cgrp) in sequence and genomic organization. In this study, we identified five Crsps, Crsp-1 to Crsp-5, in dogs. Crsp-1 has five exons with an exon-intron organization identical to that of porcine Crsp-1 or Crsp-2, while Crsp-2 and Crsp-3 have additional CT-2- and CT-3-coding exons like Ct/Cgrp. Crsp-2 was renamed as Ct-2/Crsp-2 because both CRSP-2 and CT-2 mRNAs were tissue-specifically expressed. Crsp-4 and Crsp-5 are presumably generated by retrotransposition. We postulate that Crsps were generated from the gene duplication of Ct/Cgrp, and gained their diversity during mammalian evolution. Among the canine CTs and CRSPs, CRSP-1, CT-1 and CT-2 are active ligands for the CT-R, but CRSP-2 and others are inactive. Canine CRSP-1 and CT-2 are expressed in the central and peripheral systems, while CT-1 is localized in the thyroid gland. These findings indicate that dogs can be used for an experimental model as analysing the physiological roles of the CT/CGRP/CRSP family.

Abstract
Adrenomedullin 5 (AM5) is a new member of the calcitonin gene-related peptide (CGRP) family identified in teleost fish. Although its presence was suggested in the genome database of mammals, molecular identity and biological function of AM5 have not been examined yet. In this study, we cloned a cDNA encoding AM5 in the pig and examined its cardiovascular and renal effects. Putative mature AM5 was localized in the middle of prohormone and had potential signals for intermolecular ring formation and C-terminal amidation. The AM5 gene was expressed most abundantly in the spleen and thymus. Several AM5 genes were newly identified in the database of mammals, which revealed that the AM5 gene exists in primates, carnivores, and undulates but could not be identified in rodents. In primates, nucleotide deletion occurred in the mature AM5 sequence in anthropoids (human and chimp) during transition from the rhesus monkey. Synthetic mature AM5 injected intravenously into rats induced dose-dependent decreases in arterial pressure at 0.1-1 nmol/kg without apparent changes in heart rate. The decrease was maximal in 1 min and AM5 was approximately half as potent as AM. AM5 did not cause significant changes in urine flow and urine Na+ concentration at any dose. In contrast to the peripheral vasodepressor action, AM5 injected into the cerebral ventricle dose-dependently increased arterial pressure and heart rate at 0.1-1 nmol. The increase reached maximum more quickly after AM5 (5 min) than AM (15-20 min). AM5 added to the culture cells expressing calcitonin receptor-like receptor (CLR) or calcitonin receptor (CTR) together with one of the receptor activity-modifying proteins (RAMPs), the combination of which forms major receptors for the CGRP family, did not induce appreciable increases in cAMP production in any combination, although AM increased it at 10(-)(10)-10(-)(9) M when added to the CLR and RAMP2/3 combination. These data indicate that AM5 seems to act on as yet unknown receptor(s) for AM5, other than CLR/CTR+RAMP, to exert central and peripheral cardiovascular actions in mammals.

Abstract
INTRODUCTION We retrospectively evaluated the performance of preoperative computed tomographic (CT) colonography to detect tumor involvement of the rectosigmoid wall and predict the need for rectosigmoid resection in patients with primary ovarian cancer. METHODS Thirty-three patients with primary ovarian cancer who underwent preoperative CT colonographic examination were evaluated. The images of the examination were analyzed and compared with the subsequent surgical findings. RESULTS All abnormal findings (malignant infiltration of the rectosigmoid mucosa and extrinsic compression) revealed by conventional colonoscopy were correctly observed as extrinsic compression using CT colonography. The sensitivity, specificity, positive predictive value and negative predictive value of CT colonography for the prediction of rectosigmoid resection were 100%, 64.7%, 72.7%, and 100%, respectively. Though conventional colonoscopic examinations could not be completed in five patients because of the presence of extrinsic stenosis and occlusion at the sigmoid colon, CT colonography enabled the entire large bowel to be examined in these patients. CONCLUSIONS This preliminary study showed that the CT colonographic examination is feasible and safe. CT colonography seems to have several advantages over conventional colonoscopy for the detection of rectosigmoid involvement in patients with advanced ovarian cancer. For confirmation of the efficacy of CT colonography, further large prospective studies are needed.

Abstract
Hemolymph coagulation in arthropods plays key roles in host defense, including sealing wounds to staunch bleeding and immobilizing invading microorganisms. We have previously reported that horseshoe crab transglutaminase (TGase) promotes cross-linking of a clotting protein (coagulin) with hemocyte-derived proteins (proxins), resulting in the formation of stable coagulin fibrils. Here we show that TGase also cross-links proxins to another hemocyte-derived protein named stablin. Stablin is a cysteine-rich protein of 131 residues. Surface plasmon resonance analysis revealed the specific interaction of stablin with proxin-1 at K(d) = 4.0 x 10(-9) m. Stablin was predominantly localized in the large granules of hemocytes and secreted by lipopolysaccharide-induced exocytosis. Interestingly, stablin bound to chitin at K(d) = 1.5 x 10(-8) m, as determined by using a quartz-crystal microbalance. Stablin also interacted with lipopolysaccharides and lipoteichoic acids and exhibited bacterial agglutinating activity against Gram-positive and -negative bacteria. Immunostaining showed that stablin is co-localized with coagulin in the clotting fibrils that effectively trap bacteria. Moreover, an anti-stablin antibody strongly inhibited the proper formation of the clotting fibrils. These data suggest that stablin promotes the formation of the clotting mesh and the immobilization of invading microbes at injury sites. In arthropods, the TGase-mediated cross-linking may play an important role in the initial stage of host defense, wound closure, and healing, as in the case of mammals.

Abstract
Hepatoid adenocarcinoma is characterized histologically by neoplastic epithelial cells that resemble hepatocellular carcinoma (HCC) and produce alpha-fetoprotein (AFP). We describe a case of hepatoid adenocarcinoma of the uterus that, unlike any other previously reported case, was strictly confined to the cervix. A cervical biopsy demonstrated poorly differentiated adenocarcinoma, and hysterectomy and bilateral salpingo-oophorectomy were subsequently performed. Histologically, the lesion consisted of solid sheets of hepatoid cells accompanied with areas of endometroid adenocarcinoma. The tumor cells showed strong and diffuse cytoplasmic immunoreactivity with AFP in both medullary and adenocarcinoma components. Metastases to bilateral pelvic lymph nodes were detected 12 months after surgery. Since undergoing total pelvic irradiation, the patient has been alive and in full remission for 22 months. To our knowledge, this is the first report of primary hepatoid adenocarcinoma of the uterine cervix.

Abstract
We performed unilateral or bilateral nerve-sparing (UNS or BNS) radical hysterectomies combined with a parametrial excision in patients with locally advanced cervical cancer. The parametrial excision technique is characterized by a meticulous sharp dissection of the avascular plane outside the visceral fascia of the uterus and vagina under direct vision, providing an en bloc parametria and ensuring that all regional spread of the disease is contained within negative surgical margins. The aim of this study was to describe this surgical technique and to retrospectively evaluate the feasibility and the impact on early bladder function. From February 2005 to November 2006, 32 patients with FIGO stage IB-IIB cervical cancer, who had the tumor of more than 20 mm in diameter, underwent the UNS surgery or BNS surgery. A parametrial excision was performed in all the patients. The surgical procedure was safely completed in all the patients. Though 14 patients had tumor invasion to the parametria, none of the patients had a positive surgical margin in the parametrium. The bladder function of patients in the UNS group immediately after surgery was more damaged than that in the BNS group. However, all the patients in both groups recovered spontaneous voiding with no need of self-catheterization during the perioperative periods. This preliminary study showed that the surgical technique is feasible and safe. For confirmation of the efficacy of this technique, further large prospective studies are needed.

Abstract
AIM It has been demonstrated that the endogenous matrix metalloproteinases (MMPs) inhibitor reversion inducing cysteine rich protein with Kazal motifs (RECK) is a reliable prognostic marker for detecting several types of tumors. However, the RECK expressions in most of the normal and neoplastic tissues were extremely low, and to measure its expression is quite complicated. The purpose of the present study is to establish an easy method to quantify murine RECK mRNA expression for use in future experimental studies. Subsequently, in order to verify the reliability of the established quantification technique, we examined the change in RECK expression and gelatinase secretion in tumor cells when stimulated by the extracellular matrix. METHODS Several murine tumor cells were used in the present study. The real-time polymerase chain reaction (PCR) method and measurement conditions for murine RECK mRNA were studied using these tumor cells. Gelatinase activities were also examined by gelatin zymography. RESULTS Murine RECK mRNA expression was accurately quantified using real-time PCR. Among the tumor cells used in the study, osteosarcoma cells showed significantly higher RECK mRNA expression than the others. The RECK expression in the osteosarcoma cells was down-regulated by contact with matrigel-coated culture flasks due to increased secretion of gelatinases. CONCLUSION The real-time PCR method employed in our study is useful to quantify RECK expression.

Abstract
Tachystatin B is an antimicrobial and a chitin-binding peptide isolated from the Japanese horseshoe crab (Tachypleus tridentatus) consisting of two isopeptides called tachystatin B1 and B2. We have determined their solution structures using NMR experiments and distance geometry calculations. The 20 best converged structures of tachystatin B1 and B2 exhibited root mean square deviations of 0.46 and 0.49 A, respectively, for the backbone atoms in Cys(4)-Arg(40). Both structures have identical conformations, and they contain a short antiparallel beta-sheet with an inhibitory cystine-knot (ICK) motif that is distributed widely in the antagonists for voltage-gated ion channels, although tachystatin B does not have neurotoxic activity. The structural homology search provided several peptides with structures similar to that of tachystatin B. However, most of them have the advanced functions such as insecticidal activity, suggesting that tachystatin B may be a kind of ancestor of antimicrobial peptide in the molecular evolutionary history. Tachystatin B also displays a significant structural similarity to tachystatin A, which is member of the tachystatin family. The structural comparison of both tachystatins indicated that Tyr(14) and Arg(17) in the long loop between the first and second strands might be the essential residues for binding to chitin.

Abstract
The aim of this study was to examine the pharmacokinetics of clinically applied benzoporphyrin derivative monoacid ring-A (BPD-MA; Verteporfin), a second-generation photosensitizer, during a trial of photodynamic therapy (PDT) in nine dogs having naturally occurring neoplasms. After injecting BPD-MA at 0.5 mg/kg intravenously, its mean half-life (t1/2) was found to be 8.14 +/- 5.34 h, mean clearance (Cl) 35.13 +/- 9.62 ml/(h kg), the mean value of the volume of distribution (Vc) 0.08 +/- 0.01 l/kg and the mean steady state volume of distribution (Vss) 0.38 +/- 0.31 l/kg respectively. With the exception of a transitional increase in serum alkaline phosphatase activity, no other clinical abnormalities were observed. The t1/2 in dogs with naturally occurring tumours was longer than that in humans, but similar to that in rats. The values of Cl and Vss in dogs having naturally occurring neoplasms were lower than those in humans. It is suggested that the pharmacokinetics of BPD-MA in tumour-bearing dogs would be helpful in determining the protocol of a short drug-light interval PDT with BPD-MA that mainly targets the tumour vasculature.

Abstract
Arthropod cuticles play an important role as the first barrier against invading pathogens. We extensively determined the sequences of horseshoe crab cuticular proteins. Proteins extracted from a part of the ventral side of the cuticle were purified by chitin-affinity chromatography, and separated by two-dimensional SDS/PAGE. Proteins appearing on the gel were designated high molecular mass chitin-binding proteins, and these proteins were then grouped into classes based on their approximate isoelectric points and predominant amino acid compositions. Members of groups designated basic G, basic Y, and acidic S groups contained a so-called Rebers and Riddiford consensus found in arthropod cuticular proteins. Proteins designated acidic DE25 and DE29 each contained a Cys-rich domain with sequences similar to those of insect peritrophic matrix proteins and chitinases. In contrast, basic QH4 and QH10 contained no consensus sequences found in known chitin-binding proteins. Alternatively, a low molecular mass chitin-binding fraction was prepared by size exclusion chromatography, and 15 low molecular mass chitin-binding proteins, named P1 through P15, were isolated. With the exception of P9 and P15, all were found to be identical to known antimicrobial peptides. P9 consisted of a Kunitz-type chymotrypsin inhibitor sequence, and P15 contained a Cys-rich motif found in insulin-like growth factor-binding proteins. Interestingly, we observed transglutaminase-dependent polymerization of nearly all high molecular mass chitin-binding proteins, a finding suggests that transglutaminase-dependent cross-linking plays an important role in host defense in the arthropod cuticle, analogous to that observed in the epidermal cornified cell envelope in mammals.

Abstract
Mammalian blood coagulation is based on the proteolytically induced polymerization of fibrinogens. Initially, fibrin monomers noncovalently interact with each other. The resulting homopolymers are further stabilized when the plasma transglutaminase (TGase) intermolecularly cross-links epsilon-(gamma-glutamyl)lysine bonds. In crustaceans, hemolymph coagulation depends on the TGase-mediated cross-linking of specific plasma-clotting proteins, but without the proteolytic cascade. In horseshoe crabs, the proteolytic coagulation cascade triggered by lipopolysaccharides and beta-1,3-glucans leads to the conversion of coagulogen into coagulin, resulting in noncovalent coagulin homopolymers through head-to-tail interaction. Horseshoe crab TGase, however, does not cross-link coagulins intermolecularly. Recently, we found that coagulins are cross-linked on hemocyte cell surface proteins called proxins. This indicates that a cross-linking reaction at the final stage of hemolymph coagulation is an important innate immune system of horseshoe crabs.
