Abstract
BACKGROUND/AIM Itraconazole (ITZ), an antifungal agent, has been reported to have anti-tumor effects in patients with multiple cancer types. We investigated the involvement of tumor-associated macrophages (TAMs) in its tumor-agnostic mechanism. MATERIALS AND METHODS M1 and M2 macrophages were established from human monocyte leukemia cell line (THP-1) and their phenotypes were determined morphologically. Cell membrane antigens and secreted proteins were evaluated by western blots and enzyme-linked immunosorbent assay, respectively. The proteomic profiling of cells was done by liquid chromatography with tandem mass spectrometry and analyzed. Viability of cervical cancer cells (CaSki) was evaluated after addition of the supernatant of M2 macrophages and during co-culture with M2 macrophages, with or without 10-5 M ITZ. RESULTS Co-culture of M1 macrophages inhibited the proliferation of CaSki cells (p=0.012), while that of M2 macrophages promoted their proliferation (p<0.0001). After treatment of M2 macrophages with ITZ for 24 h, they changed into M1-like shape with decreased expression of cluster of differentiation 163 (CD163) and chemokine ligand 18 (CCL18). The M1-like shape was maintained for 7 weeks of ITZ treatment and reverted to original after ITZ removal. Proteomic analysis of ITZ treated-M2 macrophages also demonstrated M1-like signature including the elevated levels of tumor necrosis factor (TNF)-related proteins. After treatment with ITZ, both the supernatant of the M2 macrophages and the co-culture with M2 macrophages significantly inhibited the proliferation of CaSki cells (each, p<0.0001). CONCLUSION ITZ repolarized M2 macrophages to M1 type and suppressed cervical cancer cell growth demonstrating TAM-mediated anti-cancer activity of ITZ.

Abstract
Glycosylphosphatidylinositols (GPIs) are glycolipids that anchor many proteins (GPI-APs) on the cell surface. The core glycan of GPI precursor has three mannoses, which in mammals, are all modified by ethanolamine-phosphate (EthN-P). It is postulated that EthN-P on the third mannose (EthN-P-Man3) is the bridge between GPI and the protein and the second (EthN-P-Man2) is removed after GPI-protein attachment. However, EthN-P-Man2 may not be always transient, as mutations of PIGG, the enzyme that transfers EthN-P to Man2, result in inherited GPI deficiencies (IGDs), characterized by neuronal dysfunctions. Here, we show that EthN-P on Man2 is the preferential bridge in some GPI-APs, among them, the Ect-5'-nucleotidase and Netrin G2. We find that CD59, a GPI-AP, is attached via EthN-P-Man2 both in PIGB-knockout cells, in which GPI lacks Man3, and with a small fraction in wild-type cells. Our findings modify the current view of GPI anchoring and provide a mechanistic basis for IGDs caused by PIGG mutations.

Abstract
Integrated analysis of the phosphoproteome and interactome of anaplastic lymphoma kinase (ALK)-overexpressing HEK 293 cells revealed 37 ALK substrate candidates, contributing to the improvement of kinase activity prediction. The sensitivity of phosphorylation site identification by mass spectrometry has improved markedly. However, the lack of kinase–substrate relationship (KSR) data hinders the improvement of the range and accuracy of kinase activity prediction. In this study, we aimed to develop a method for acquiring systematic KSR data on anaplastic lymphoma kinase (ALK) using mass spectrometry and to apply this method to the prediction of kinase activity. Thirty-seven ALK substrate candidates, including 34 phosphorylation sites not annotated in the PhosphoSitePlus database, were identified by integrated analysis of the phosphoproteome and crosslinking interactome of HEK 293 cells with doxycycline-induced ALK overexpression. Furthermore, KSRs of ALK were validated by an in vitro kinase assay. Finally, using phosphoproteomic data from ALK mutant cell lines and patient-derived cells treated with ALK inhibitors, we found that the prediction of ALK activity was improved when the KSRs identified in this study were used instead of the public KSR dataset. Our approach is applicable to other kinases, and future identification of KSRs will facilitate more accurate estimations of kinase activity and elucidation of phosphorylation signals.

Abstract
Abstract
CD40L plays a major role in immune response and is a target for inflammatory disease therapy. Besides CD40, CD40L binds to several integrins but their role in signaling is unclear. We showed that integrins αvβ3 and α5β1 bind to the CD40L trimeric interface through classical ligand binding site of integrins (site 1). Several CD40L mutants from HIGM1 (hyper-IgM syndrome type 1) patients were clustered in trimeric interface and defective in integrin binding, and in NF-κB and B cell activation, but still bound CD40 and acted as antagonists of CD40L signaling. Thus, integrins play a critical role in CD40L signaling. Previous studies showed that CX3CL1 and sPLA2-IIA can activate integrins by binding to a recently identified allosteric site (site 2) of integrins. Using cell-free assays, we found that soluble (s)-CD40L activated soluble integrins, α4β1, αvβ3 and α5β1, and induced their binding to known specific ligands independent of inside-out signaling. Also, sCD40L activated cell-surface integrins in CHO cells lacking CD40. Finally, sCD40L bound to a cyclic peptide derived from site 2. These findings indicate that CD40L acts as an allosteric activator of integrins by binding to site 2. Docking simulation predicted that the integrin site 2-binding site of CD40L is located outside of CD40L trimer. Importantly, four HIGM1 mutations are clustered in the predicted site 2-binding site of CD40L. The K143T and G144E mutants were the most defective in integrin activation, indicating that integrin binding occurs around these residues of the predicted site 2-binding site. We propose that allosteric integrin activation by CD40L plays a role in CD40L signaling and that defective integrin site 2-binding may be causal for defective CD40L signaling in HIGM1.

Abstract
Histiocytic sarcoma (HS) is a haematopoietic tumour of histiocyte origin that has been sporadically reported in four-toed hedgehogs (Atelerix albiventris). The present study aimed to investigate clinical, gross, histopathological and immunohistochemical features of HS in eight hedgehogs. Histological and immunohistochemical features of normal histiocytes and Langerhans cells (LCs) of hedgehogs were also investigated. HLA-DR-, Iba-1- and E-cadherin-positive LCs were observed in the epidermis, while Iba-1- and CD204-positive histiocytes were detected in the lymph nodes and spleen of normal hedgehogs. Localized HS (six cases) developed in the skin and spleen, while disseminated HS (two cases) occurred in the intestine. Tumour cells of disseminated HS were also distributed within the mesenteric lymph nodes, liver, kidney, spleen, lung and adrenal glands. Tumour cells of both localized and disseminated HS were composed of histiocytic cells, spindle to pleomorphic cells, multinucleated giant cells and erythrophagocytic cells. Most tumour cells were immunopositive for Iba-1, CD204 and lysozyme. A small number of tumour cells were positive for E-cadherin and CD208, and the tumour cells in one case were positive for HLA-DR. These results suggest that the tumour cells have variable features of histiocyte origin, including dendritic cells, LCs and macrophages. The behaviour of HS in the hedgehog was very aggressive, and 50% of cases died within 90 days of resection. The present study also highlighted the tendency for local tumour recurrence in localized cutaneous HS cases, suggesting a requirement for a long-term follow-up after excision.

Abstract
Inhibition of hypoxia-inducible factor prolyl hydroxylase domain (HIF-PHD) promotes erythropoietin (EPO) production by stabilizing the HIFα subunit. Thieno[2,3-d]pyrimidine 8 identified based on X-ray crystal structure analysis was optimized to lead to the discovery of pyrazolo[4,3-d]pyrimidine 13 as the lead compound of orally bioavailable HIF-PHD inhibitors. Conversion of the benzyl moiety in 13 gave pyrazolopyrimidine 19 with high solubility and bioavailability, which increased hemoglobin levels in anemic model rats after repeated oral administration. It was shown that pyrazolo[4,3-d]pyrimidine derivatives are promising therapeutic agents for renal anemia through the inhibition of HIF-PHD.

Abstract
Prion diseases are transmissible, lethal neurodegenerative disorders caused by accumulation of the aggregated scrapie form of the prion protein (PrPSc) after conversion of the cellular prion protein (PrPC). The glycosylphosphatidylinositol (GPI) anchor of PrPC is involved in prion disease pathogenesis, and especially sialic acid in a GPI side chain reportedly affects PrPC conversion. Thus, it is important to define the location and structure of the GPI anchor in human PrPC Moreover, the sialic acid linkage type in the GPI side chain has not been determined for any GPI-anchored protein. Here we report GPI glycan structures of human PrPC isolated from human brains and from brains of a knock-in mouse model in which the mouse prion protein (Prnp) gene was replaced with the human PRNP gene. LC-electrospray ionization-MS analysis of human PrPC from both biological sources indicated that Gly229 is the ω site in PrPC to which GPI is attached. Gly229 in human PrPC does not correspond to Ser231, the previously reported ω site of Syrian hamster PrPC We found that ∼41% and 28% of GPI anchors in human PrPCs from human and knock-in mouse brains, respectively, have N-acetylneuraminic acid in the side chain. Using a sialic acid linkage-specific alkylamidation method to discriminate α2,3 linkage from α2,6 linkage, we found that N-acetylneuraminic acid in PrPC's GPI side chain is linked to galactose through an α2,3 linkage. In summary, we report the GPI glycan structure of human PrPC, including the ω-site amino acid for GPI attachment and the sialic acid linkage type.

Abstract
Glycosylphosphatidylinositol (GPI)-anchored proteins and glycosphingolipids interact with each other in the mammalian plasma membranes, forming dynamic microdomains. How their interaction starts in the cells has been unclear. Here, based on a genome-wide CRISPR-Cas9 genetic screen for genes required for GPI side-chain modification by galactose in the Golgi apparatus, we report that β1,3-galactosyltransferase 4 (B3GALT4), the previously characterized GM1 ganglioside synthase, additionally functions in transferring galactose to the N-acetylgalactosamine side-chain of GPI. Furthermore, B3GALT4 requires lactosylceramide for the efficient GPI side-chain galactosylation. Thus, our work demonstrates previously unexpected functional relationships between GPI-anchored proteins and glycosphingolipids in the Golgi. Through the same screening, we also show that GPI biosynthesis in the endoplasmic reticulum (ER) is severely suppressed by ER-associated degradation to prevent GPI accumulation when the transfer of synthesized GPI to proteins is defective. Our data demonstrates cross-talks of GPI biosynthesis with glycosphingolipid biosynthesis and the ER quality control system. Glycosylphosphatidylinositol (GPI) anchors are found on many cell surface proteins but their biosynthesis is not fully understood. Here, the authors identify genes involved in GPI galactosylation and reveal functional connections between GPI processing, glycosphingolipid biosynthesis and ER-associated degradation.

Abstract
Abstract
Background
Palliative sedation is a therapeutic option when symptom relief is difficult to achieve at the end-of-life. However, little is known regarding palliative sedation in terminally ill heart failure (HF) patients.
Purpose
To survey the practice of palliative sedation in terminally ill HF patients at a tertiary referral cardiovascular center, and to investigate the efficacy and safety of sedative agents in HF patients.
Methods
We retrospectively reviewed consecutive patients who were referred to palliative care team at our institution between September 2013 and August 2018. Patients who were hospitalized for HF and died during hospitalization despite optimal medical therapy were selected and defined as terminally ill HF. We investigated the practice of palliative sedation in terminally ill HF patients and analysed the vital signs and sedation scale before starting sedative agents and about 1 hour afterward.
Results
Among 95 terminally ill HF patients, 37 were prescribed palliative sedation at the end-of-life (Picture). Of 37 patients (mean age: 70 years, median B-type natriuretic peptide: 1018 pg/ml, median creatinine: 3.0 mg/dl, intravenous inotrope: 81%), 25 were prescribed dexmedetomidine, and 12 were prescribed midazolam as first agent for sedation. Patient's backgrounds were comparable between the two groups. Richmond Agitation-Sedation Scale was significantly reduced (P<0.01), whereas blood pressure and heart rate were not altered after treatments in both groups. In midazolam group, significant decreases were noted regarding respiratory rate (P=0.01) and oxygen saturation (P=0.02); however, these parameters were not changed in dexmedetomidine group (Table).
Table 1. Vital signs and sedation scale Dexmedetomidine group (n=25) Midazolam group (n=12) Baseline After P value Baseline After P value Richmond Agitation-Sedation Scale 1 (0, 1) −1 (−2, 0) <0.01 1 (0, 1) −2 (−3, −1) <0.01 Vital signs Systolic blood pressure (mmHg) 90±15 89±16 0.51 89±21 84±23 0.33 Diastolic blood pressure (mmHg) 52±13 54±11 0.34 60±14 56±23 0.48 Heart rate (beats per minute) 95±20 91±22 0.17 90±21 90±19 0.70 Respiratory rate (breaths per minute) 22±5 20±5 0.24 21±5 17±2 0.01 Oxygen saturation (%) 97±3 96±6 0.59 96±5 94±5 0.02
Picture. Study flowchart
Conclusions
Dexmedetomidine and midazolam were commonly used in real-word practice for HF patients at the end-of-life. Although impact on respiratory system differed by treatments, both agents could be prescribed effectively and safely in terminally ill HF patients.

Abstract
Proper control of cell migration is critically important in many biologic processes, such as wound healing, immune surveillance, and development. Much progress has been made in the initiation of cell migration; however, little is known about termination and sometimes directional reversal. During active cell migration, as in wound healing, development, and immune surveillance, the integrin expression profile undergoes drastic changes. Here, we uncovered the extensive regulatory and even opposing roles of integrins in directional cell migration in electric fields (EFs), a potentially important endogenous guidance mechanism. We established cell lines that stably express specific integrins and determined their responses to applied EFs with a high throughput screen. Expression of specific integrins drove cells to migrate to the cathode or to the anode or to lose migration direction. Cells expressing αMβ2, β1, α2, αIIbβ3, and α5 migrated to the cathode, whereas cells expressing β3, α6, and α9 migrated to the anode. Cells expressing α4, αV, and α6β4 lost directional electrotaxis. Manipulation of α9 molecules, one of the molecular directional switches, suggested that the intracellular domain is critical for the directional reversal. These data revealed an unreported role for integrins in controlling stop, go, and reversal activity of directional migration of mammalian cells in EFs, which might ensure that cells reach their final destination with well-controlled speed and direction.-Zhu, K., Takada, Y., Nakajima, K., Sun, Y., Jiang, J., Zhang, Y., Zeng, Q., Takada, Y., Zhao, M.

Abstract
BACKGROUND AND AIMS T2 gallbladder cancer requires lymph node dissection for curative resection, whereas simple cholecystectomy is adequate to treat T1 gallbladder cancer. Hence, this study aimed to develop an accurate scoring system to preoperatively predict pT2 in gallbladder cancer. MATERIAL AND METHODS We retrospectively assessed data from 57 patients with suspected gallbladder cancer who underwent curative resection between September 2003 and May 2017. Six with apparent invasion of adjacent organs on preoperative images were excluded. We evaluated preoperative computed tomography, magnetic resonance and endoscopic ultrasonographic images, blood biochemistry, and the maximum standard uptake value in fluorodeoxyglucose-positron emission tomography images. We analyzed whether correlations between preoperative findings and the depth of tumor invasion could predict pT2. RESULTS The pathological diagnosis was gallbladder cancer in 30 (58.8%) patients, of whom 21 (69.9%) had pT2 or worse. Multivariate analyses selected carcinoembryonic antigen and tumor diameter as independent predictors of pT2 or worse (odds ratios = 1.741 and 1.098, respectively; 95% confidence intervals = 1.004-3.020 and 1.008-1.197, respectively). A regression formula was created using carcinoembryonic antigen and tumor diameter to calculate pT2 predictive scores. The area under the receiver operating characteristics curve of the pT2 predictive score was 0.873. CONCLUSION We created a scoring system to predict pT2 in gallbladder cancer using carcinoembryonic antigen and tumor diameter. The present findings suggested that carcinoembryonic antigen is important for the preoperative evaluation of gallbladder cancer.

Abstract
SummaryA simple, specific and reproducible method for determination of plasminogen activator activity in rat ovaries has been developed by using the chromogenic substrate S-2251. The two steps of enzymatic reactions, i. e. activation of plasminogen and subsequent hydrolysis of the substrate was performed in one step incubation. A linear relationship was observed between the amount of chromogen produced and activator activity in the range of the optical density from 0.05 to 1.20 for 30 min’s incubation. Endogenous activity of non-specific proteases, plasmin or plasmin inhibitors which might be contained in rat ovaries turned out not to interfere with the specificity of a standardized assay procedure. Reproducibility was firmly established with coefficient of variation not exceeding 10%. Using this method, a marked increase followed by a drastic decrease in the activator activity was shown with rat ovaries around the time of ovulation after the injection of human chorionic gonadotropin.

Abstract
SummarySephadex gel filtration of human plasma gave results suggesting the presence of two proactivators of plasminogen, termed proactivators A and B.Activity resembling that of proactivator A was found in rabbit plasma, but not in guinea pig plasma.Plasminogen activators produced by the interaction of proactivator A of human plasma with streptokinase had no caseinolytic or TAMe esterolytic effect.Proactivator A can be separated in a form apparently free from plasminogen, as shown by the heated fibrin plate test and by immunological analysis. On the other hand, proactivator B concentrates prepared so far are contamined with plasminogen.Human proactivators appear to be far more susceptible to streptokinase than are rabbit proactivators.Inhibitors of the fibrinolysin system were observed in the plasmas of all 3 species. These inhibitors are not present in the euglobulin fraction of plasma. Sephadex fractionation of euglobulin fractions results in proactivator preparations that do not contain inhibitors.

Abstract
Many eukaryotic proteins are anchored to the cell surface via the glycolipid glycosylphosphatidylinositol (GPI). Mammalian GPIs have a conserved core but exhibit diverse N-acetylgalactosamine (GalNAc) modifications, which are added via a yet unresolved process. Here we identify the Golgi-resident GPI-GalNAc transferase PGAP4 and show by mass spectrometry that PGAP4 knockout cells lose GPI-GalNAc structures. Furthermore, we demonstrate that PGAP4, in contrast to known Golgi glycosyltransferases, is not a single-pass membrane protein but contains three transmembrane domains, including a tandem transmembrane domain insertion into its glycosyltransferase-A fold as indicated by comparative modeling. Mutational analysis reveals a catalytic site, a DXD-like motif for UDP-GalNAc donor binding, and several residues potentially involved in acceptor binding. We suggest that a juxtamembrane region of PGAP4 accommodates various GPI-anchored proteins, presenting their acceptor residue toward the catalytic center. In summary, we present insights into the structure of PGAP4 and elucidate the initial step of GPI-GalNAc biosynthesis.

Abstract
INTRODUCTION In 2013, a total of 1586 kidney transplants were performed in Japan, and 1431 (90.2%) of the organs were from living donors. The purpose of this study is to illuminate the awareness of living kidney donors toward kidney donation after the condition of the recipient changed, thus clarifying the influence of that recognition on the donor. METHODS This study design was qualitative descriptive research. Transplant coordinators at 4 hospitals were commissioned to screen subject candidates and hand-deliver printed research explanations to them. Candidates who responded were selected as subjects. I conducted semistructured interviews and analyzed them using the grounded theory approach. This research was approved by the Ethics Research Committee, Faculty of Nursing, Toho University. RESULTS The survey period was from April to November 2014, and consent was obtained from 5 donors and 5 recipients. The outcome of recipients who received kidneys from the 5 donors was as follows: recovered after temporary worsening (n = 3), early graft loss (n = 1), and early death (n = 1). The core category was "to the donor, the meaning of kidney donation is continually redefined." The donors had a strong interest in the physical condition of the recipient. The 3 changes in the recipients' physical condition, defined as "recovery," "temporary worsening," and "complete deterioration," affected the donor's condition. CONCLUSION Due to changes in the recipient's physical condition, donors' psychological and physical condition and their definition of the meaning of kidney donation also changed. Health care systems that guarantee lifelong follow-up of the physical and psychological condition of donors after donation are needed.

Abstract
OBJECTIVES The purpose of this study was to examine the effects of long-term wheel-running on tibia bone properties in T2DM Otsuka Long-Evans Tokushima Fatty (OLETF) rats. METHODS Ten five-week-old male OLETF rats were used as experimental animals and 5 Long-Evans Tokushima Otsuka (LETO) rats as controls. Half of OLETF rats performed daily voluntary wheel-running for 17 months (OLETF-EXE), while neither the remainder of OLETF nor LETO rats had exercise. At the end of experiment, in addition to serum biochemical and bone formation/resorption marker analyses, bone mass, trabecular bone microarchitecture and cortical bone geometry were analyzed in left tibia, and bone mechanical strength of right tibia was measured. RESULTS Tibia bone mass, trabecular bone microarchitecture, cortical bone geometry and bone mechanical strength deteriorated in diabetic OLETF rats. However, such deterioration was obviously attenuated in OLETF-EXE rats, which maintained normal levels of blood glucose, HbA1c and blood urea nitrogen. CONCLUSIONS Daily wheel-running could prevent the deterioration of bone properties in OLETF rats. This would be induced mainly by suppressing the development of T2DM. Regular physical exercise may be a potent strategy for preventing not only the development of diabetes but also the deterioration of bone properties in patients with chronic T2DM.

Abstract
Lee et al. show that PGAP6 is a glycosylphosphatidylinositol (GPI)-specific phospholipase A2 expressed on the cell surface. PGAP6 selectively acts on a GPI anchor of CRIPTO, but not its close homologue CRYPTIC, and modulates Nodal signaling during embryonic development. Glycosylphosphatidylinositol-anchored proteins (GPI-APs) can be shed from the cell membrane by GPI cleavage. In this study, we report a novel GPI-processing enzyme, termed post-glycosylphosphatidylinositol attachment to proteins 6 (PGAP6), which is a GPI-specific phospholipase A2 mainly localized at the cell surface. CRIPTO, a GPI-AP, which plays critical roles in early embryonic development by acting as a Nodal coreceptor, is a highly sensitive substrate of PGAP6, whereas CRYPTIC, a close homologue of CRIPTO, is not sensitive. CRIPTO processed by PGAP6 was released as a lysophosphatidylinositol-bearing form, which is further cleaved by phospholipase D. CRIPTO shed by PGAP6 was active as a coreceptor in Nodal signaling, whereas cell-associated CRIPTO activity was reduced when PGAP6 was expressed. Homozygous Pgap6 knockout mice showed defects in early embryonic development, particularly in the formation of the anterior–posterior axis, which are common features with Cripto knockout embryos. These results suggest PGAP6 plays a critical role in Nodal signaling modulation through CRIPTO shedding.

Abstract
Ferroelectric (Pb,La)(Zr,Ti)O3 (PLZT) capacitors were fabricated with Pt, Al:ZnO (AZO), or Sn:In2O3 (ITO) top electrodes. Hydrogen- or deuterium-induced degradation was investigated for the three capacitors by annealing in a 3% H2/balance N2 or 3% D2/balance N2 ambient environment at 200 °C and 1 torr. The remnant polarization of all capacitors decreased after annealing in both H2 and D2 ambient after 45 min, and the remnant polarization of the Pt/PLZT/Pt capacitor significantly decreased after 45-min annealing compared with that of the AZO/PLZT/Pt and ITO/PLZT/Pt capacitors, even though the initial remnant polarization for the Pt/PLZT/Pt capacitor was larger. Time-of-flight secondary ion mass spectrometry showed slight differences in hydrogen content for the three different capacitors after H2 annealing. In contrast, the deuterium content of the Pt/PLZT/Pt and AZO/PLZT/Pt or ITO/PLZT/PT capacitors was significantly different after deuterium annealing. Deuterium depth profiles for the Pt/PLZT/Pt capacitor after annealing showed that deuterium conformally exists in the PLZT layer of the Pt/PLZT/Pt capacitor, and deuterium accumulation under the Pt bottom electrode was also observed. This result suggests that diffusion of deuterium in Pt was much higher than that in PLZT. AZO and ITO top electrodes could act as a hydrogen barrier layer for ferroelectric films.

Abstract
ONO-4641 is a next-generation sphingosine 1-phosphate (S1P) receptor agonist selective for S1P receptors 1 and 5. The objective of the study was to characterize the immunomodulatory effects of ONO-4641 using preclinical data. ONO-4641 was tested in both in-vitro pharmacological studies as well as in-vivo models of transient or relapsing-remitting experimental autoimmune encephalomyelitis (EAE). In vitro, ONO-4641 showed highly potent agonistic activities versus S1P receptors 1 and 5 [half maximal effective concentration (EC(50) ) values of 0·0273 and 0·334 nM, respectively], and had profound S1P receptor 1 down-regulating effects on the cell membrane. ONO-4641 decreased peripheral blood lymphocyte counts in rats by inhibiting lymphocyte egress from secondary lymphoid tissues. In a rat experimental autoimmune encephalomyelitis (EAE) model, ONO-4641 suppressed the onset of disease and inhibited lymphocyte infiltration into the spinal cord in a dose-dependent manner at doses of 0·03 and 0·1 mg/kg. Furthermore, ONO-4641 prevented relapse of disease in a non-obese diabetic mouse model of relapsing-remitting EAE. These observations suggest that ONO-4641 may provide therapeutic benefits in the treatment of multiple sclerosis.

Abstract
Alterations of the p53 and Ki-ras genes were examined in 12 human pancreatic cancer-derived cell lines with different metastatic potential. Point mutations of the Ki-ras gene at codon 12 were found in 10 out of 12 cell lines (83%), while abnormalities of the p53 gene were identified in 8 out of 12 cell lines (67%) which included point mutations (n=7) and one base deletion (n=1). The comparison between alterations of the p53 and Ki-ras genes showed that all the 12 cell lines revealed alterations of both genes or one of these genes regardless of the metastatic potential. Further, same alterations of the Ki-ras gene or p53 gene were noted among the cell lines with increased metastatic potential and their parental cell lines. These findings suggest that alterations of the p53 gene, like the Ki-ras gene is a frequent event in pancreatic cancer, and could contribute cooperatively in the oncogenic steps of pancreatic cancer. It is also suggested that the genetic changes of the p53 and Ki-ras genes are not substantially associated with the metastatic potential in pancreatic cancer.
