Abstract
BACKGROUND Chemotherapy is frequently used in cancer treatment; however, it may cause adverse events, which must be managed. Reactive oxygen species (ROS) have been reported to be involved in the induction of intestinal mucositis and diarrhea, which are common side effects of treatment with fluoropyrimidine 5-fluorouracil (5-FU). Our previous studies have shown that oral administration of cystine and theanine (CT) increases glutathione (GSH) production in vivo. In the present study, we hypothesized that CT might inhibit oxidative stress, including the overproduction of ROS, and attenuate 5-FU-induced mucositis and diarrhea. METHODS We investigated the inhibitory effect of CT administration on mucositis and diarrhea, as well as its mechanism, using a mouse model of 5-FU-induced intestinal mucositis. RESULTS CT administration suppressed 5-FU-induced diarrhea and weight loss in the studied mice. After 5-FU administration, the GSH level and the GSH/GSSG ratio in the small intestine mucosal tissue decreased compared to normal control group; but CT administration improved the GSH/GSSG ratio to normal control levels. 5-FU induced ROS production in the basal region of the crypt of the small intestine mucosal tissue, which was inhibited by CT. CT did not affect the antitumor effect of 5-FU. CONCLUSIONS CT administration suppressed intestinal mucositis and diarrhea in a mouse model. This finding might be associated with the antioxidant characteristics of CT, including the improved rate of GSH redox and the reduced rate of ROS production in the small intestine mucosal tissue. CT might be a suitable candidate for the treatment of gastrointestinal mucositis associated with chemotherapy.

Abstract
A fault-tolerant quantum processor may be configured using stationary qubits interacting only with their nearest neighbours, but at the cost of significant overheads in physical qubits per logical qubit. Such overheads could be reduced by coherently transporting qubits across the chip, allowing connectivity beyond immediate neighbours. Here we demonstrate high-fidelity coherent transport of an electron spin qubit between quantum dots in isotopically-enriched silicon. We observe qubit precession in the inter-site tunnelling regime and assess the impact of qubit transport using Ramsey interferometry and quantum state tomography techniques. We report a polarization transfer fidelity of 99.97% and an average coherent transfer fidelity of 99.4%. Our results provide key elements for high-fidelity, on-chip quantum information distribution, as long envisaged, reinforcing the scaling prospects of silicon-based spin qubits.

Abstract
We report implementation of a resonantly driven singlet-triplet spin qubit in silicon. The qubit is defined by the two-electron antiparallel spin states and universal quantum control is provided through a resonant drive of the exchange interaction at the qubit frequency. The qubit exhibits long T_{2}^{*} exceeding 1 μs that is limited by dephasing due to the ^{29}Si nuclei rather than charge noise thanks to the symmetric operation and a large micromagnet Zeeman field gradient. The randomized benchmarking shows 99.6% single gate fidelity which is the highest reported for singlet-triplet qubits.

Abstract
While single-shot detection of silicon spin qubits is now a laboratory routine, the need for quantum error correction in a large-scale quantum computing device demands a quantum non-demolition (QND) implementation. Unlike conventional counterparts, the QND spin readout imposes minimal disturbance to the probed spin polarization and can therefore be repeated to extinguish measurement errors. Here, we show that an electron spin qubit in silicon can be measured in a highly non-demolition manner by probing another electron spin in a neighboring dot Ising-coupled to the qubit spin. The high non-demolition fidelity (99% on average) enables over 20 readout repetitions of a single spin state, yielding an overall average measurement fidelity of up to 95% within 1.2 ms. We further demonstrate that our repetitive QND readout protocol can realize heralded high-fidelity (>99.6%) ground-state preparation. Our QND-based measurement and preparation, mediated by a second qubit of the same kind, will allow for a wide class of quantum information protocols with electron spins in silicon without compromising the architectural homogeneity. Conventional qubit readout methods in silicon spin qubits destroy the quantum state, precluding any further computations based on the outcome. Here, the authors demonstrate quantum non-demolition readout using a second qubit of the same kind, making for a scalable approach.

Abstract
Single-spin qubits in semiconductor quantum dots hold promise for universal quantum computation with demonstrations of a high single-qubit gate fidelity above 99.9% and two-qubit gates in conjunction with a long coherence time. However, initialization and readout of a qubit is orders of magnitude slower than control, which is detrimental for implementing measurement-based protocols such as error-correcting codes. In contrast, a singlet-triplet qubit, encoded in a two-spin subspace, has the virtue of fast readout with high fidelity. Here, we present a hybrid system which benefits from the different advantages of these two distinct spin-qubit implementations. A quantum interface between the two codes is realized by electrically tunable inter-qubit exchange coupling. We demonstrate a controlled-phase gate that acts within 5.5 ns, much faster than the measured dephasing time of 211 ns. The presented hybrid architecture will be useful to settle remaining key problems with building scalable spin-based quantum computers. The race to produce a quantum computer has driven the development of many different qubit designs with different benefits and drawbacks. Noiri et al. demonstrate a hybrid device with two coupled semiconductor spin qubits of different designs, which should allow each qubit’s advantages to be exploited.

Abstract
We extract the phase coherence of a qubit defined by singlet and triplet electronic states in a gated GaAs triple quantum dot, measuring on time scales much shorter than the decorrelation time of the environmental noise. In this nonergodic regime, we observe that the coherence is boosted and several dephasing times emerge, depending on how the phase stability is extracted. We elucidate their mutual relations, and demonstrate that they reflect the noise short-time dynamics.

Abstract
We demonstrate fast universal electrical spin manipulation with inhomogeneous magnetic fields. With fast Rabi frequency up to 127 MHz, we leave the conventional regime of strong nuclear-spin influence and observe a spin-flip fidelity >96%, a distinct chevron Rabi pattern in the spectral-time domain, and a spin resonance linewidth limited by the Rabi frequency, not by the dephasing rate. In addition, we establish fast z rotations up to 54 MHz by directly controlling the spin phase. Our findings will significantly facilitate tomography and error correction with electron spins in quantum dots.

Abstract
Cancer cells produce energy through aerobic glycolysis, but contributions of host tissues to cancer energy metabolism are unclear. In this study, we aimed to elucidate the cancer-host energy production relationship, in particular, between cancer energy production and host muscle. During the development and progression of colorectal cancer, expression of the secreted autophagy-inducing stress protein HMGB1 increased in the muscle of tumor-bearing animals. This effect was associated with decreased expression of pyruvate kinase PKM1 and pyruvate kinase activity in muscle via the HMGB1 receptor for advanced glycation endproducts (RAGE). However, muscle mitochondrial energy production was maintained. In contrast, HMGB1 addition to colorectal cancer cells increased lactate fermentation. In the muscle, HMGB1 addition induced autophagy by decreasing levels of active mTOR and increasing autophagy-associated proteins, plasma glutamate, and (13)C-glutamine incorporation into acetyl-CoA. In a mouse model of colon carcinogenesis, a temporal increase in HMGB1 occurred in serum and colonic mucosa with an increase in autophagy associated with altered plasma free amino acid levels, increased glutamine, and decreased PKM1 levels. These differences were abolished by administration of an HMGB1 neutralizing antibody. Similar results were obtained in a mouse xenograft model of human colorectal cancer. Taken together, our findings suggest that HMGB1 released during tumorigenesis recruits muscle to supply glutamine to cancer cells as an energy source.

Abstract
In this study, a newly developed innovative triaxial testing system to investigate strength, deformation behavior, and/or permeability of gas hydrate bearing-sediments in deep sea is described. Transport of the pressure core from the storage chamber to the interior of the sealing sleeve of a triaxial cell without depressurization was achieved. An image processing technique was used to capture the motion and local deformation of a specimen in a transparent acrylic triaxial pressure cell and digital photographs were obtained at each strain level during the compression test. The material strength was successfully measured and the failure mode was evaluated under high confining and pore water pressures.

Abstract
Imaging MS combined with CE/MS serves as a method to provide semi-quantitative and spatial information of small molecular metabolites in tissue slices. However, not all metabolites including amino acids have fully been visualized, because of low-ionization efficiency in MALDI MS. This study aimed to acquire semi-quantitative spatial information for multiple amino acids in frozen tissue slices. As a derivatization reagent, p-N,N,N-trimethylammonioanilyl N'-hydroxysuccinimidyl carbamate iodide (TAHS) was applied to increase their ionization efficiency and detection sensitivity. Semi-quantitative MALDI-imaging MS allowed us to visualize and quantify free amino acid pools in human colon cancer xenografts using a model of liver metastases in super-immunodeficient NOD/scid/γ(null) mice (NOG mice). Because the m/z values of several TAHS-derivatized amino acids overlap with those of the 2,5-dihydroxybenzoic acid background and other endogenous compounds, we imaged them with tandem MS. The results indicated that regional contents of glutamate, glutamine, glycine, leucine/isoleucine/hydroxyproline, phenylalanine, and alanine were significantly elevated in metastatic tumors versus parenchyma of tumor-bearing livers. On-tissue TAHS derivatization thus serves as a useful method to detect alterations in many amino acid levels in vivo, thereby enabling understanding of the spatial alterations of these metabolites under varied disease conditions including cancer.

Abstract
MALDI imaging mass spectrometry (IMS) provides information about the spatial distribution of metabolites within thin slices of tissue, and has been used to elucidate complex phenotypes under various physiological conditions. Previously, our group reported distinct spatial distribution of a variety of metabolites in experimental model of hepatic micrometastasis of the solid tumor. However the metabolic properties in tumor and host tissues are not fully characterized, because of difficulty in visualizing most amino acids, due to their lower ionization efficiency.
Here, by using of p-N,N,N-trimethylammonioanily N’-hydroxysuccinimidyl carbamate iodide (TAHS) as a derivatizing reagent, we have successfully developed the method for the detection of various amino acids simultaneously by MALDI-MS on tissue section. We prepared liver section from hepatic metastasis model of human colon cancer, and then performed MALDI-IMS. To compare the signal intensities of amino acids among the different sections, we normalized the MALDI-IMS data with the quantified value of each amino acid obtained from capillary electrophoresis-mass spectrometry. The result indicated the amount of glycine, phenylalanine, leucine, glutamate, and glutamine were significantly elevated in metastatic foci compared to liver parenchyma. Other metabolites such as ATP and glutathione also accumulated in metastatic foci, and these results suggested that increased amino acid pool were required to maintain ATP and GSH levels in tumor.
In conclusion, we have demonstrated that novel imaging technique by using of IMS combined with on-tissue TAHS derivatization enables the visualization of amino acid distribution in tissue. The current method could be powerful tool to elucidate the mechanism for metabolic changes of cancer disease in vivo.

Abstract
Abstract
Although maintained in healthy human, it is well known that plasma amino acid profiles are changed in various pathologic conditions, including liver disorder and cancer. We have previously reported the potential use of plasma amino acid profiling as diagnosis for several cancer disease. However, some questions remained for the mechanisms. The changes in plasma amino acid profiles in tumor disease were regulated by a lot of factors, including metabolic changes of tumors and immune cells. In this study, we focused on the role of immune cells, especially myeloid derived suppressor cells (MDSC). MDSC are characterized as immature myeloid cells that are precursors of dendritic cells, macrophages, and/or granulocytes, they are considered to accumulate in the blood, lymph nods, and at tumor sites in most patients and experimental animals with cancer and inhibit anti-tumor inflammation. Therefore we hypothesized that MDSC were involved in the changes in plasma amino acid profiles in tumor disease. To test our hypothesis, we employed C57BL/6 mice tumor model in which Lewis lung carcinoma (3LL) was injected subcutaneously. Using flow cytometry analysis, a significant percentage of MDSC were detected in spleens of tumor-bearing mice as compared to control normal mice. To assess the role of MDSC in the changes in plasma amino acid profile, we eliminated MDSC from the tumor-bearing mice by inducing apoptosis cell death on MDSC selectively in vivo. Flow cytometry results showed a significant decrease in the percentage of CD11b+ Gr1+ cells in splenocytes derived from MDSC deleted tumor-bearing mice as compared to tumor-bearing mice. To study the immunogenic effects of the MDSC deletion on the tumor-bearing mice, we performed histological analysis (H&E staining) and extensive areas of inflammation within 3LL subcutaneous tumors were observed after the MDSC deletion. In addition, we investigated the effects of the MDSC deletion on the percentage of splenic T cell subpopulations by Flow cytometry. The percentage of CD4+ and CD8+ T cells were increased in spleens of MDSC deleted tumor-bearing mice compared to untreated tumor-bearing mice. To evaluate the effects of the MDSC depletion on the plasma amino acid profiles, plasma samples were collected from normal mice, tumor-bearing mice, and MDSC deleted tumor-bearing mice. Plasma amino acid concentration were measured by LC-MS. The MDSC deletion significantly changed the concentrations of some amino acids in plasma compared to the untreated tumor-bearing mice and normal mice. These changes in plasma amino acid concentrations were partially impeded by adoptive transfer of MDSC from tumor-bearing mice. Altogether, these results suggest that MDSC may be involved in the changes in plasma amino acid profiles in tumor disease.

Abstract
Alteration of the plasma free amino acid profile was reported to be a potential marker of colorectal cancer and breast cancer. The plasma amino acid profile has been reported as a relevant marker for early detection of colorectal cancer (Okamoto N et al. Int J Med Med Sci, 2009). In the present study, we examined the plasma amino acid profile as a marker for evaluating colon cancer risk. The amino acid profiles were examined in the mouse plasma using DMH-induced C57BL6 mouse colon carcinogenesis model. The plasma amino acid profiles of DMH-treated mice were different from that in control mice. Importantly, the plasma amino acid profile at procarcinogenic phase was also distinguished from the control. We focused on HMGB1, which was timely increased in serum and colon mucosa of the DMH-treated mice. In HMGB1-adeministrated mice, the plasma amino acid profiles showed a resemble pattern with that in the procarcinogenic phase mice. Decrease of most amino acids in the liver and skeletal muscle suggested an increase of catabolism in HMGB1-treated mice. In the mouse liver and muscle tissues, HMGB1 decreased pyruvate kinase M1 expression, and tetrazolium desoxydation, whereas lactate production was not increased. HMGB1 decreased phosphorylation levels of mTOR and increased protein levels of Beclin1 and LC3 in mouse liver and muscle tissue, whereas a mitochondrial marker, Diablo was not affected. Inhibitor of p38 MAPK abrogated HMGB1-induced autophagy signals. These findings suggest that HMGB1 affects energy production in mitochondria and activates autophagy signals, which might induce protein degradation and subsequent alteration of plasma amino acid profiles. The change of the plasma amino acid profiles might be a key finding detecting procarcinogenic status of the colon.

Abstract
Abstract
Metabolic changes in patients with various disorders, including liver disease and cancer, lead to alterations in amino acid balance, and plasma amino acid profiles can be used to discriminate between non-malnourished patients with cancer and healthy individuals. Not with standing, the mechanisms of amino acid imbalance are not well understood. In patients with cancer, various factors including metabolic changes in the tumor itself and immune responses may affect plasma amino acid levels. To investigate involvement of the immune system, we measured plasma amino acid levels in an orthotopic transplant model of colon cancer established in both conventional BALB/c mice and athymic BALB/c nude mice (T-lymphocyte-deficient mice).
CT26 colon cancer cells (murine colon cancer cell line) were implanted into the cecal wall of the BALB/c mice (n=10) and nude mice (n=10). Plasma samples were collected from the tumor-bearing mice at 7 and 14 days after transplantation, and changes in plasma amino acid profiles were compared. Plasma was also collected from mice that underwent sham operation (control mice, n=10). Plasma amino acid concentrations were measured by LC/MS/MS.
The plasma concentrations of several amino acids changed significantly in tumor-bearing mice compared to concentrations in control mice. Although cells from the same line were injected into the cecal wall of BALB/c mice and nude mice, a difference was noted in the change in plasma amino acid levels. Plasma Val, Ile, Leu, and Met levels decreased in BALB/c mice but increased in nude mice. There was no difference in the amino acid profile of CT26 tumor tissues between BALB/c mice and nude mice. We then injected antiCD3-antibody into the peritoneal cavity of tumor-bearing BALB/c mice (n=5) to eliminate T-cell function. We also injected IgG into tumor-bearing BALB/c mice (n=5) for control. The pattern of change in amino-acid profiles differed between the two groups of mice.
Our findings suggest that T-lymphocyte-mediated immunoreactions are involved in changes in the plasma amino acid profile in patients with colorectal cancer.

Abstract
The available evidence from numerous clinical studies has failed to demonstrate a clear and consistent relationship between monosodium glutamate (MSG) and asthma. The objective of this study was to investigate the effects of MSG on bronchial inflammation by measuring cytological, histological and functional changes in an ovalbumin-induced asthma mouse model. BALB/c mice with experimentally induced asthma were fed a diet containing 0.5% or 5% MSG the week before the first ovalbumin injection and for the subsequent 3-week period. MSG feeding did not affect pulmonary eosinophil infiltration, production of Th2 cytokines, circulating IgE concentrations or airway hyperresponsiveness (induced by methacholine). Histological observations did not reveal pulmonary inflammation, including secondary changes, in the asthmatic mice. An oral gavage challenge with an MSG solution (0.5% or 5%, w/w) did not exert any acute effects on lung inflammation or airway hyperresponsiveness in the asthmatic mice. The results of this study suggest that MSG is not involved in the development of asthma or in acute asthmatic responses, and they support previous observations from well-designed clinical studies.

Abstract
We have been proposing the functional distinction of two classes of macrophages (Mp), namely the reductive macrophages (RMp) with high intracellular content of glutathione (GSH) and the oxidative macrophages (OMp) with reduced content. At the same time we have been investigating the variation of RMp/OMp balance during aging of mice, especially in relation to the age related onset of autoimmune diseases. In this paper we have investigated the Th1/Th2 balance of thioredoxin (TRX) transgenic (Tg) mice, with prolonged life longevity, during aging in the context of the intracellular redox status of Mp, which has been hypothesized to be crucial in regulating the Th1/Th2 balance. It was confirmed that peritoneal resident Mp of Tg mice showed the higher GSH/GSSG ratios compared with that of age matched wild type (WT) mice. The predominance of RMp was associated with the sustained maintenance of Th1 prevalence during aging until 2 years in Tg mice, whereas WT littermates showed rapid polarization to Th2 around the age of 8 months. The Tg mice showed elevation of IFN-gamma and reduction of IL-10 with moderate change of IL-4 produced by CD4+ T cells. The WT mice showed inverse changes of IFN-gamma/IL-4 and IFN-gamma/IL-10 ratios during aging. In addition, IL-10 production by Mp was dramatically reduced in aged Tg mice. Thus, TRX Tg mice may be useful to investigate the contribution of the anti-oxidant defense mechanism during aging accompanied with increasing oxidative stress.

Abstract
We determined whether inhibition of the catalytic tyrosine kinase activity of the receptors for vascular endothelial growth factor/vascular permeability factor (VEGF/VPF) inhibits the formation of malignant ascites and the progressive growth of human ovarian carcinoma cells implanted into the peritoneal cavity of nude mice. The novel protein tyrosine inhibitor PTK 787 was evaluated in two models of human ovarian cancer: Hey-A8 cells, which express low levels of VEGF/VPF and grow as solid tumor foci on the surface of peritoneal organs, and SKOV3 i.p.1 cells, which express high levels of VEGF/VPF and grow as solid peritoneal tumors and ascites. Treatment of nude mice by daily oral administration of 50 mg/kg PTK 787 was not effective against Hey-A8 tumors. In sharp contrast, it significantly inhibited growth of SKOV3 i.p.1 cells and formation of ascites, significantly increasing survival of mice with the implants. Tumor-induced vascular hyperpermeability in the peritoneum of tumor-bearing mice was inhibited by PTK 787, which accounted for its inhibition of ascites formation. Our results suggest that blockade of the VEGF/VPF receptor may be an efficient strategy to inhibit formation of malignant ascites and growth of VEGF/VPF-dependent human ovarian carcinomas.

Abstract
We determined whether the angiogenesis and growth of murine colon carcinomas growing in the wall of the cecum is dependent on infiltrating leukocytes. Syngeneic BALB/c or SCID mice were treated with a myelosuppressive, maximally tolerated dose of doxorubicin. Parental or multidrug resistant CT-26 colon carcinoma cells were implanted into the cecal wall 3 days after the second intravenous injection of doxorubicin. Control mice developed large, well-vascularized tumors, whereas doxorubicin-pretreated mice did not. Intravenous injection of spleen cells from normal BALB/c or SCID mice one day prior to tumor cell implantation reversed the decreased vascularity and tumorigenicity. The production of proangiogenic molecules and microvessel density in tumors directly correlated with the number of infiltrating leukocytes, suggesting that tumor-infiltrating leukocytes are essential to angiogenesis of murine colon carcinomas.

Abstract
Granulocyte-macrophage colony-stimulating factor (GM-CSF)-transduced B16-F10 murine melanoma cells had lower tumorigenicity in both syngeneic and nude mice than parental or LacZ-transduced (control) cells. The subcutaneous (s.c.) tumors producing GM-CSF were densely infiltrated with macrophages, whereas the control tumors were not. In vitro studies showed that GM-CSF-transduced B16 cells were susceptible to lysis mediated by nonactivated murine macrophages, whereas control B16 cells were not. Macrophage-mediated cytotoxicity against GM-CSF-transduced B16 cells was independent of the presence of NO, H2O2, O2-, tumor necrosis factor alpha, and matrix metalloproteinase. Coculture experiments using GM-CSF-producing and -nonproducing B16 cells demonstrated that GM-CSF produced by the transduced B16 cells activated macrophages to kill the bystander non-GM-CSF-producing tumor cells. The results suggest that GM-CSF released by tumor cells can induce macrophage-mediated cytotoxicity, which in turn can inhibit the in vivo growth of GM-CSF-transduced tumor cells.

Abstract
We determined whether tumor cells consistently generating granulocyte/macrophage colony- stimulating factor (GM-CSF) can recruit and activate macrophages to generate angiostatin and, hence, inhibit the growth of distant metastasis. Two murine melanoma lines, B16-F10 (syngeneic to C57BL/6 mice) and K-1735 (syngeneic to C3H/HeN mice), were engineered to produce GM-CSF. High GM-CSF (>1 ng/10(6) cells)- and low GM-CSF (<10 pg/10(6) cells)-producing clones were identified. Parental, low, and high GM-CSF-producing cells were injected subcutaneously into syngeneic and into nude mice. Parental and low-producing cells produced rapidly growing tumors, whereas the high-producing cells produced slow-growing tumors. Macrophage density inversely correlated with tumorigenicity and directly correlated with steady state levels of macrophage metalloelastase (MME) mRNA. B16 and K-1735 subcutaneous (s.c.) tumors producing high levels of GM-CSF significantly suppressed lung metastasis of 3LL, UV-2237 fibrosarcoma, K-1735 M2, and B16-F10 cells, but parental or low-producing tumors did not. The level of angiostatin in the serum directly correlated with the production of GM-CSF by the s.c. tumors. Macrophages incubated with medium conditioned by GM-CSF- producing B16 or K-1735 cells had higher MME activity and generated fourfold more angiostatin than control counterparts. These data provide direct evidence that GM-CSF released from a primary tumor can upregulate angiostatin production and suppress growth of metastases.

Abstract
The purpose of this study was to determine whether retrovirus-mediated transfer of the murine macrophage inducible nitric oxide synthase (iNOS) gene can inhibit tumorigenicity and metastasis of human renal cancer cells. Retroviral vectors encoding murine macrophage iNOS were constructed in the pLXSN retroviral vector with the iNOS gene under the control of a long terminal repeat promoter and a neomycin resistance gene under the control of an internal simian virus 40 promoter. Highly metastatic human renal carcinoma SN12PM6 cells were infected with control or iNOS retrovirus. Expression of iNOS was confirmed by Northern and Western blot analyses, and expression of the functional iNOS protein, i.e., production of nitric oxide (NO), was determined by measuring nitrite accumulation in culture supernatants. Noninfected or control cells produced large orthotopic tumors in the kidney of nude mice and a larger number of experimental lung metastases, whereas iNOS-infected cells produced small tumors in the kidneys and few to no lung metastases. The data indicate that the infection of human renal cancer cells by retroviruses harboring the murine iNOS gene can induce the production of high levels of NO, which is associated with autocytotoxicity, suppression of tumorigenicity, and abrogation of metastasis.

Abstract
This study was designed to determine the relative activity of basic fibroblast growth factor (bFGF), vascular endothelial growth factor/vascular permeability factor (VEGF/VPF), platelet-derived growth factor (PDGF), platelet-derived endothelial cell growth factor (PD-ECGF), hepatocyte growth factor (HGF), and interleukin-8 (IL-8) in regulating endothelial cell division, migration, degradation of the extracellular matrix (ECM), morphogenesis, and survival. Human umbilical vein endothelial cells (HUVEC) were treated with different concentrations of the six cytokines. bFGF was the most potent mitogen followed by VEGF/VPF and PD-ECGF. VEGF/VPF and bFGF also enhanced the survival of the endothelial cells in serum-free medium. Interstitial collagenase (MMP-1) and urokinase plasminogen activator (uPA) were significantly upregulated only by bFGF. HGF, bFGF, and VEGF/VPF induced chemotactic migration of the endothelial cells, but only HGF (scatter factor) enhanced nondirectional motility. The organization of endothelial cells to form tubes on Matrigel was induced by bFGF and, to a lesser extent, by VEGF/VPF and IL-8. Permeability across endothelial cell monolayers was induced only by VEGF/VPF. These data demonstrate that different angiogenic molecules differentially regulate distinct steps in the process of angiogenesis, suggesting that any given molecule may be necessary but in itself insufficient for establishment of a viable vasculature.

Abstract
BACKGROUND By the time patients are diagnosed with ovarian carcinoma, peritoneal dissemination of the tumor often has occurred. The progressive growth and spread of ovarian carcinoma depend, in part, on the formation of an adequate blood supply. We determined whether the expression of genes that regulate distinct steps in angiogenesis (i.e., the formation of new blood vessels) was associated with the pattern and progressive growth of human ovarian carcinomas implanted in the peritoneal cavity of nude mice. METHODS Five different human ovarian carcinomas were injected individually into the peritoneal cavity of female NCr-nu/nu nude mice. The expression of basic fibroblast growth factor, vascular endothelial growth factor/vascular permeability factor (VEGF/VPF), interleukin 8 (IL-8), and collagenase type IV (MMP-2 [matrix metalloproteinase-2] and MMP-9) was determined by northern blot analysis, in situ hybridization of messenger RNA, and immunohistochemical analysis. Blood vessel distribution and density, macrophage infiltration pattern, and stromal reaction were determined by immunohistochemical analysis with specific antibodies. RESULTS Three of the carcinomas produced both solid lesions and ascitic tumors, whereas the remaining two produced only solid lesions. Two of the carcinomas produced rapidly progressive disease, two produced slow disease, and one produced intermediate disease. The formation of ascites was directly associated with expression of VEGF/ VPF, and survival was inversely associated with expression of IL-8. In rapidly growing tumors, the number of blood vessels was high throughout the lesion; in contrast, in slow-growing tumors, most vessels (and infiltrating macrophages) were located at the periphery. CONCLUSIONS The expression of various genes that regulate angiogenesis in human ovarian carcinomas is associated with the pattern of the disease and its progression. Therefore, targeting specific genes that regulate angiogenesis could offer new approaches to the treatment of ovarian cancer.

Abstract
We investigated the parasympathetic nervous response to psychological test using heart rate variation (HRV) during deep breathing in elderly patients with hand-arm vibration syndrome and healthy controls. Average age (SD) of 16 patients with vibration-induced white finger (VWF), 13 patients without VWF and 12 healthy controls was 60.1 (2.8), 60.6 (4.2) and 58.8 (3.8), respectively. After an initial supine rest for 40 min, psychological test (Stroop color word test and mirror drawing test) was performed for 20 min. The indexes of HRV (Mean R-R, SD, RMSSD and CV) were calculated. Blood pressure and heart rate were also measured. The indexes of HRV did not differ between the groups before exposure. The SD, RMSSD and CV of the patients without VWF during supine deep breathing after 3 min post-exposure supine rest were significantly lower than those of the control group (p < 0.05). The Mean R-R of the patients without VWF significantly increased (p < 0.05). Blood pressure did not differ in either before or after exposure measurements. The results suggest that the post-exposure response of the parasympathetic nervous system to psychological test reduced in the patients without VWF.

Abstract
The purpose of this study was to determine whether retrovirus-mediated transfer of murine macrophage inducible nitric oxide synthase (iNOS) can produce inhibition of tumorigenicity and metastasis. Retroviral vectors encoding macrophage iNOS constructed in pLXSN, a retroviral vector with the iNOS gene under the control of a long terminal repeat promoter, were stably transfected into PA317 cells. Medium harvested from confluent monolayers of the virus-producing cell lines was used for infection of the murine K-1735 melanoma cells. Expression of iNOS was confirmed by northern and Western blot analyses. Functional iNOS protein expression was confirmed by bioassay of nitrite accumulation in the culture supernatant. Cells infected by a control iNOS-negative retrovirus produced fast-growing subcutaneous tumors and many lung metastases in nude mice, whereas iNOS-transduced cells produced slow-growing tumors and few lung metastases, showing that the infection of murine tumor cells by retroviruses harboring the iNOS gene can suppress tumorigenicity and metastasis.

Abstract
BACKGROUND Development of new blood vessels is essential for tumor growth and metastasis and depends on the production of angiogenic factors by tumor and/or infiltrating cells. We previously showed that vascular endothelial growth factor (VEGF) expression and vessel count correlate with metastasis in human colon cancer. Although most tumors with high vessel counts express high levels of VEGF, some do not. Recently, platelet-derived endothelial cell growth factor (PD-ECGF), another potent angiogenic factor, has been reported to be expressed in colon cancer. PURPOSE In this study, we examined the role of PD-ECGF in colon cancer angiogenesis and whether PD-ECGF is derived from the tumor or infiltrating cells. METHODS Immunostaining for PD-ECGF was performed on 96 colon cancer specimens, some of which were previously stained for VEGF and factor VIII, a marker that is specific for endothelial cells. Double staining was done by using antibodies to PD-ECGF and to CD68 (macrophage specific) or CD3 (lymphocyte specific) to confirm which infiltrating cells produce PD-ECGF. Northern blot analysis for PD-ECGF messenger RNA (mRNA) was performed on four colon cancer specimens and corresponding normal colon mucosae (same patients) and four human colon cancer cell lines (KM12SM, SW620, HT29, and NCI-H508) to determine whether colon cancer epithelium expresses PD-ECGF. RESULTS Immunohistochemical analysis demonstrated that PD-ECGF was expressed in infiltrating cells in most of the colon cancer specimens (80 [83%] of 96) but rarely in tumor epithelium (five [5%] of 96). Double staining demonstrated that infiltrating cells staining positive for both PD-ECGF and CD68 were more predominant than those staining positive for both PD-ECGF and CD3. The intensity of staining for PD-ECGF in infiltrating cells correlated with vessel counts (Spearman's rank correlation coefficient (R) = .29; P = .004), but did not correlate with the intensity of VEGF staining (R = .176, P = .086) or metastasis (Mann-Whitney U test, P = .253). PD-ECGF staining intensity was higher in specimens with a high vessel count (> 50 at high magnification) and low VEGF-staining intensity (< or = 2+) than in specimens with a high vessel count (again, > 50) and high VEGF-staining intensity (3+). Northern blot analysis revealed that colon cancer specimens and normal mucosae expressed relatively high levels of PD-ECGF mRNA, whereas PD-ECGF mRNA transcripts were not detectable in colon cancer cell lines. CONCLUSIONS AND IMPLICATIONS PD-ECGF expression in human colon cancer specimens is associated with vessel count and may be responsible for tumor vascularity in those tumors with low VEGF expression. Infiltrating cells expressing PD-ECGF may contribute to angiogenesis, thus providing an additional mechanism for tumor neovascularization.

Abstract
A case of mandibular myofibroma in a 2-month-old boy is presented. Including this case, 24 pediatric and 11 adult patients with maxillofacial myofibroma have been reported since 1981. Of the 24 pediatric patients, 15 (62.5%) had lesions affecting the mandible. The adult cases had no mandibular involvement. Histologic evaluation of the tissue specimen revealed an interlacing pattern of spindle-shaped cells with long oval nuclei. Tissue immunohistochemical staining found it to be reactive for antibodies directed against vimentin and alpha-smooth muscle actin, but not desmin, S-100 protein, neuron-specific enolase, or myoglobin. Electron microscopy examination revealed the following cells: myofibroblast-like cells, fibroblast-like cells, and intermediate cells that were similar to the fibroblast-like cells except for the presence of a few microfilaments. Myoblast-like cells were not seen.

Abstract
Cellular responses to fibronectin (FN) are likely to have a complex molecular basis involving the interactions between multiple functional domains of FN and specific cell surface molecules. We have utilized several types of recombinant FN fragments and their chimeric fragments to examine the regulatory mechanisms of the spreading and chemotactic migration of HT1080 human fibrosarcoma cells on FN. The CH-271 fusion fragment, in which the cell-binding domain (C-274) of FN is adjacent to the heparin-binding domain (H-271), promoted cell spreading more efficiently than C-274, H-271, or their mixture (C-274 + H-271) over a 60-min incubation. The CH-271 variants containing various modules in the heparin-binding domain (CHV peptide) showed different promotion of cell migration, spreading, and vinculin accumulation at focal adhesion, respectively. The preincubation of the cells with heparitinase I resulted in significant inhibition of chemotactic migration to FN and its fragments containing the III13 and/or III14 modules of the heparin-binding domain. Additionally, migration to CH-271 was inhibited by the presence of the RGDS peptide in a concentration-dependent fashion. Thus, the spread and migration responses of HT1080 cells onto FN fusion peptides require the adjacent coexistence of cell- and heparin-binding domains and are mediated by the interactions between cell surface heparan sulfate and the heparin-binding domain, in concert with the interaction between cell surface integrin and the cell-binding domain. In conclusion, our present study demonstrated that fusion peptides of fibronectin can efficiently induce two signals from the cell-binding and heparin-binding domains required for the completion of cell spreading, the formation of focal contact, and motility at the early stage of the culture, suggesting that the III13 or III14 modules within the heparin-binding domain are responsible for the initiation of different cellular responses.

Abstract
Aminopeptidase N/CD13 is a Zn(2+)-dependent exoprotease present on the cell surface as a transmembrane protein. Our previous studies using aminopeptidase inhibitors and antibodies demonstrated that aminopeptidase N is involved in the degradation and invasion of the extracellular matrix (ECM) by metastatic tumor cells. In the present study we transfected human A375M melanoma cells with eukaryotic plasmid expression vectors that contained full length cDNA of aminopeptidase N/CD13 and examined their characteristics. The transfectants that expressed extremely high levels of aminopeptidase N/CD13 degraded type IV collagen and invaded ECM more actively than the parental and control vector-transfected cells. Furthermore, the aminopeptidase N/CD13-transfected A375M cells had significantly augmented lung colonizing potential in nude mice. The results show that the aminopeptidase N/CD13 plays an active role in degradation and invasion of ECM and may be involved in the molecular mechanisms of blood-borne metastasis.

Abstract
We have investigated the inhibitory mechanism of the initial arrest of L5178Y-ML25 lymphoma cells in a target organ (liver) by using recombinant fibronectin fragments with cell- and/or heparin-binding domains (C-274, H-271 or the fusion fragment CH-271). Pretreatment of hepatic sinusoidal endothelial (HSE) cell monolayers with lymphoma cells or their conditioned medium for 4 to 6 h resulted in the enhancement of lymphoma cell adhesion to HSE cell monolayer. The increased tumor adhesiveness was completely abolished by preincubation of the conditioned medium with anti interleukin-1 beta monoclonal antibody (mAb). Synthetic sialyl Le(x) (SLe(x)) as a ligand for endothelial cell leukocyte adhesion molecule-1 (ELAM-1) adhesion receptor and anti ELAM-1 mAb blocked the conditioned medium-induced enhancement of tumor-endothelial cell interaction, while pretreatment of the activated HSE cell monolayer with anti vascular cell adhesion molecule-1 (VCAM-1) mAb did not affect the enhanced tumor cell adhesion. These results indicate that tumor cell interaction with the stimulated HSE cells is mediated by ELAM-1 molecules on HSE cells. However, the expression of SLe(x) and SLe(a) on the tumor surface was not observed by flow cytometric analysis. ELAM-1-mediated enhancement of tumor cell adhesion to HSE monolayer was also inhibited in a concentration-dependent manner by CH-271 fusion polypeptide or the sulfated chitin derivative sulfated carboxymethyl-chitin, which can bind to the heparin-binding domain of CH-271. In addition, CH-271 inhibited not only tumor-endothelium interaction but also tumor cell invasion into reconstituted basement membrane Matrigel in vitro.

Abstract
Degradation of the extracellular matrix by metalloproteinases is a critical phenomenon in cancer invasion and metastasis. Recent studies have revealed that minocycline (minocycline hydrochloride, a tetracycline) suppresses in vivo and in vitro mammalian collagenolytic activity. We investigated whether minocycline inhibited in vitro invasion and experimental pulmonary metastasis in subline-2 of streptozotocin-induced mouse renal adenocarcinoma (MRAC-PM2) cells. In vitro invasion assay demonstrated that treatment with 0.5 microgram/ml or 5.0 micrograms/ml minocycline significantly inhibited the invasion of MRAC-PM2 cells. In addition, intraperitoneal administration of 0.5 mg per mouse minocycline reduced the number of metastatic nodules in the lung when MRAC-PM2 cells were injected intravenously. Minocycline also suppressed type IV collagenolytic activity of the cells. However, the drug did not affect [3H]-thymidine uptake, growth of subcutaneously inoculated cells, attachment to the extracellular matrices, or haptotactic migration of the cells. These results indicated that the inhibitory action of type IV collagen degradation by minocycline can contribute, in part, to suppression of the in vitro invasion and metastatic potential of MRAC-PM2 cells.

Abstract
We have examined the influence of fibroblasts on the invasive and migratory potential of highly metastatic melanoma B16-BL6 and weakly metastatic B16-F1 cells in vitro. Co-culture of B16-BL6 cells with a fibroblast monolayer without cellular contact in a Transwell chamber more effectively induced tumor-cell invasion into Matrigel basement membrane than co-culture of B16-F1 cells with a fibroblast monolayer. The activity was closely correlated with the chemotactic migration of tumor cells toward the fibroblast monolayer. We also found that the conditioned medium (CM) from the co-culture of fibroblasts with B16-BL6 cells without cellular contact, i.e., CM (B16-BL6/fibroblast), rather than from co-culture with B16-F1 cells, could potentially promote the migration of tumor cells of both types. Tumor cells did not chemotactically migrate to the CM (B16-BL6), CM (B16-F1) or CM (fibroblast). Antibodies against TGF-beta 1 or FN almost completely abolished the chemotactic migration of B16-BL6 cells to the CM (B16-BL6/fibroblast) or CM (TGF-beta 1-treated fibroblast) when these antibodies were co-incubated with fibroblasts and either B16-BL6 or TGF-beta 1. In contrast, the anti-EGF antibody did not show any inhibitory effects. Analysis of amounts of TGF-beta 1 or FN in various CM using ELISA plates, and using their specific antibodies, revealed that the concentration of TGF-beta 1 in the CM (B16-BL6) was slightly higher than in the CM (B16-F1), and the amount of FN in the CM (B16-BL6/fibroblast) was twice as high as in the CM (B16-F1/fibroblast). These results suggest that TGF-beta 1 released from B16-BL6 cells can stimulate fibroblasts to produce FN; consequently, the tumor cells were able to chemotactically migrate toward the released FN, and the differences in invasive and migratory activities towards fibroblasts in B16-BL6 and B16-F1 cells may in part be due to the amounts of TGF-beta 1 from tumor cells and of FN from TGF-beta 1-stimulated fibroblasts.

Abstract
We investigated the influence of epidermal growth factor (EGF) and transforming growth factor (TGF)-beta 1 on the in vitro invasion and type IV collagenolytic activity of two new cell lines of renal cell carcinoma (SRCC-1P and SRCC-1M). When cells were treated with EGF or with TGF-beta 1, EGF increased the number of cells penetrating through the reconstituted basement membrane in SRCC-1P. In contrast, TGF-beta 1 suppressed the number of cells penetrating through the membrane in SRCC-1M. In accordance with the invasiveness, EGF enhanced the activity of type IV collagenolysis in SRCC-1P, and TGF-beta 1 suppressed it in SRCC-1M. The growth factors did not affect DNA synthesis of the cells as evaluated by 3H-thymidine incorporation. These results suggest that EGF and TGF-beta 1 can influence the in vitro invasive process of renal cell carcinoma cells through their actions on proteolysis such as type IV collagenolysis.

Abstract
We have synthesized a new compound in which Arg-Gly-Asp-Ser (RGDS) was conjugated with 6-O-sulfated and 6-O-carboxymethyl-chitin (SCM-chitin), i.e. SCM-chitin-RGDS, and tested the inhibitory effect on lung and liver metastases of three different types of tumors in mice. SCM-chitin-RGDS was more effective for the inhibition of liver metastasis of L5178Y-ML25 lymphoma and lung metastases of colon 26 M3.1 cells than SCM-chitin, RGDS or their mixture. GRGDS peptide, however, required a higher dose (3000 micrograms) to obtain a sufficiently antimetastatic effect. Intermittent i.v. administration of SCM-chitin-RGDS before or after the i.v. inoculation of L5178Y-ML25 cells caused significant inhibition of liver metastasis as compared with the multiple administration of RGDS, SCM-chitin or untreated control. Co-injection of lymphoma cells with SCM-chitin-RGDS or multiple treatment of SCM-chitin-RGDS after tumor inoculation showed significantly enhanced survival rate. SCM-chitin-RGDS also showed the spontaneous lung metastasis produced by intrafootpad injection of B16-BL6 melanoma cells by the multiple i.v. administrations. These results demonstrate that the conjugation of RGDS peptide with SCM-chitin led to augmentation of therapeutic potential to cancer metastasis, thus implying an importance of the conjugation of cell-adhesive RGDS peptide with structurally heparin-like SCM-chitin, which possess binding ability to the heparin-binding domain of fibronectin or laminin and extremely low anticoagulant properties.

Abstract
A rare case of right submandibular inflammatory pseudotumor in a 63-year-old man is reported. The tumor appeared as a symptomless swelling in the submandibular region and resembled a malignant neoplasm on computed tomographic and magnetic resonance images. Surgical resection was required. The pertinent English and Japanese literature is reviewed, and histologic and electron microscopic findings are discussed.
