Abstract
CXCL8 is the most representative chemokine produced autocrine or paracrine by tumor cells, endothelial cells and lymphocytes. It can play a key role in normal tissues and tumors by activating PI3K-Akt, PLC, JAK-STAT, and other signaling pathways after combining with CXCR1/2. The incidence of peritoneal metastasis in ovarian and gastric cancer is extremely high. The structure of the peritoneum and various peritoneal-related cells supports the peritoneal metastasis of cancers, which readily produces a poor prognosis, low 5-year survival rate, and the death of patients. Studies show that CXCL8 is excessively secreted in a variety of cancers. Thus, this paper will further elaborate on the mechanism of CXCL8 and the peritoneal metastasis of ovarian and gastric cancer to provide a theoretical basis for the proposal of new methods for the prevention, diagnosis, and treatment of cancer peritoneal metastasis.

Suppression of galectin-4 attenuates peritoneal metastasis of poorly differentiated gastric cancer cells. Gastric Cancer 2023; 26:352-363. [PMID: 36695981 DOI: 10.1007/s10120-023-01366-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2022] [Accepted: 01/14/2023] [Indexed: 01/26/2023]
Abstract
BACKGROUND Peritoneal dissemination, most often seen in metastatic and/or recurrent gastric cancer, is an inoperable condition that lacks effective treatment. The use of molecular targeted drugs is also limited; therefore, identifying novel therapeutic targets and improving our understanding of this metastatic cancer are an urgent requirement. In this study, we focused on galectin-4, which is specifically expressed in poorly differentiated cells with high potential for peritoneal dissemination. METHODS We knocked out the galectin-4 gene in NUGC4 cells using CRISPR/Cas9-mediated genome editing. Proliferation and peritoneal cancer formation in knockout cells were compared with those in wild-type and galectin-4 re-expressing cells. Western blotting and proximity ligation assays were performed to identify associated molecules affected by the expression of galectin-4. The effect of galectin-4 knockdown on cell proliferation and peritoneal metastasis was studied using a specific siRNA. Expression of galectin-4 in peritoneal metastatic tumors from 10 patients with gastric cancer was examined by immunohistochemistry. RESULTS Suppression of galectin-4 expression reduced proliferation and peritoneal metastasis of malignant gastric cancer cells. Galectin-4 knockout and knockdown reduced the expression of activated c-MET and CD44. Galectin-4 was found to interact with several proteins on the cell surface, including CD44 and c-MET, via its carbohydrate-binding ability. Immunohistochemistry showed galectin-4 expression in peritoneal metastatic tumor cells in all patients examined. CONCLUSIONS We clarified the role of galectin-4 in the development of peritoneal dissemination of poorly differentiated gastric cancer cells. Our data highlight the diagnostic and therapeutic potential of galectin-4 in the peritoneal dissemination of gastric cancer.

Cancer Treat Rev 2021; 100:102285.

Abstract
Esophageal and gastric malignancies are associated with poor prognosis, in part due to development of recurrences or metastases after curative treatment. The transforming growth factor β (TGF-β) pathway might play a role in the development of treatment resistance. In this systematic review, we provide an overview of preclinical studies investigating the role of TGF-β in esophageal and gastric malignancies. We systematically searched MEDLINE/PubMed and EMBASE for eligible preclinical studies describing the effect of TGF-β or TGF-β inhibition on hallmarks of cancer, such as proliferation, migration, invasion, angiogenesis and immune evasion. In total, 2107 records were screened and 45 articles were included, using mouse models and 45 different cell lines. TGF-β failed to induce apoptosis in twelve of sixteen tested cell lines. TGF-β could either decrease (five cell lines) or increase proliferation (seven cell lines) in gastric cancer cells, but had no effect in esophageal cancer cells. In all esophageal and all but two gastric cancer cell lines, TGF-β increased migratory, adhesive and invasive capacities. In vivo studies showed increased metastasis in response to TGF-β treatment. Additionally, TGF-β was shown to induce vascular endothelial growth factor production and differentiation of cancer-associated fibroblasts and regulatory T-cells. In conclusion, we found that TGF-β enhances hallmarks of cancer in most gastric and esophageal cancer cell lines, but not in all. Therefore, targeting the TGF-β pathway could be an attractive strategy in patients with gastric or esophageal cancer, but additional clinical trials are needed to define patient groups who would benefit most.

Abstract
BACKGROUND Patients with estrogen receptor negative (ER-) breast cancer have poor prognosis due to high rates of metastasis. However, there is no effective treatment and drugs for ER- breast cancer metastasis. Our purpose of this study was to evaluate the effect of lotus leaf alcohol extract (LAE) on the cell migration and metastasis of ER- breast cancer. METHODS The anti-migratory effect of LAE were analyzed in ER- breast cancer cells including SK-BR-3, MDA-MB-231 and HCC1806 cell lines. Cell viability assay, wound-healing assay, RNA-sequence analysis and immunoblotting assay were used to evaluate the cytotoxicity and anti-migratory effect of LAE. To further investigate the inhibitory effect of LAE on metastasis in vivo, subcutaneous xenograft and intravenous injection nude mice models were established. Lung and liver tissues were analyzed by the hematoxylin and eosin staining and immunoblotting assay. RESULTS We found that lotus LAE, not nuciferine, inhibited cell migration significantly in SK-BR-3, MDA-MB-231 and HCC1806 breast cancer cells, and did not affect viability of breast cancer cells. The anti-migratory effect of LAE was dependent on TGF-β1 signaling, while independent of Wnt signaling and autophagy influx. Intracellular H2O2 was involved in the TGF-β1-related inhibition of cell migration. LAE inhibited significantly the breast cancer cells metastasis in mice models. RNA-sequence analysis showed that extracellular matrix signaling pathways are associated with LAE-suppressed cell migration. CONCLUSIONS Our findings demonstrated that lotus leaf alcohol extract inhibits the cell migration and metastasis of ER- breast cancer, at least in part, via TGF-β1/Erk1/2 and TGF-β1/SMAD3 signaling pathways, which provides a potential therapeutic strategy for ER- breast cancer.

Abstract
Although CD133 is a representative cancer stem cell marker, its function in tumor aggressiveness under hypoxia remains unclear. Therefore, the present study aimed to investigate the associations between CD133, the epithelial-mesenchymal transition and distant metastasis in colorectal cancer. CD133+ and CD133− cells were isolated from a single colorectal cancer cell line LoVo, and their adhesive and migratory properties were compared under hypoxic conditions. Immunostaining analysis was performed to determine CD133 expression in clinical samples of primary tumors, as well as liver and peritoneal metastases. Under hypoxia, the expression levels of hypoxia-inducible factor (HIF)-1α and the epithelial-mesenchymal transition markers N-cadherin and vimentin were significantly higher in the CD133+ compared with those in the CD133− cells. Furthermore, the migratory ability of the CD133+ cells was higher compared with that of the CD133− cells under hypoxia. By contrast, the expression levels of β1 integrin were significantly lower in the CD133+ cells under hypoxia compared with those in the CD133− cells. Immunohistochemical analysis of clinical samples revealed that the levels of CD133 expression in metastatic tissues from the liver were significantly higher compared with those in the corresponding primary tumors, whereas CD133 expression levels in peritoneal metastatic tissues were significantly lower compared with those in the corresponding primary tumors. In conclusion, compared with the CD133− cells, the CD133+ colorectal cancer cells exhibited enhanced levels of HIF-1α expression and tumor cell migration during hypoxia. This was associated with an increased ability of epithelial-mesenchymal transition, possibly leading to the acquisition of an increased hematogenous metastatic potential and eventually resulting in liver metastasis. High β1 integrin expression levels in the CD133− cells under hypoxia may serve a key role in cell adhesion to the peritoneum, resulting in peritoneal metastasis.

Abstract
It has recently been recognized that inflammatory cytokines, such as tumor necrosis factor-α (TNF-α), upregulate the secretion of matrix metalloproteinase-9 (MMP-9) from cancer cells and thereby promote peritoneal dissemination. In this study, we found that TNF-α also stimulated peritoneal mesothelial cells to secrete MMP-9 as assessed by zymography. MMP-9 gene expression in mesothelial cells induced by TNF-α was confirmed by quantitative RT-PCR analysis. We then utilized the reconstituted artificial mesothelium, which was composed of a monolayer of mesothelial cells cultured on a Matrigel layer in a Boyden chamber system, to examine the effects of TNF-α on carcinoma cell invasion. The transmigration of MKN1 human gastric carcinoma cells through the reconstituted mesothelium was promoted by TNF-α in a dose-dependent manner. The increased MKN1 cell migration was partially inhibited by the anti-α3 integrin antibody, indicating that the invasion process involves an integrin-dependent mechanism. Finally, we observed that the invasion of MMP-9-knockdown MKN1 cells into Matrigel membranes was potentiated by the exogenous addition of purified proMMP-9. These results suggest that TNF-α-induced MMP-9 secretion from mesothelial cells plays an important role in the metastatic dissemination of gastric cancer.

Abstract
The prognosis of patients with peritoneal dissemination from gastric cancer is poor, and the underlying molecular mechanism remains unclear. Exosomes, as macromolecular phospholipid bilayer vesicles comprising of proteins, nucleic acids and lipids, serve as mediators of cell-cell communication. Gastric cancer tumor-derived exosomes may be involved in the pathological process of peritoneal dissemination by mediating crosstalk between cancer cells and mesothelial cells, to result in the induction of enhanced tumor growth, migratory, adhesive and invasive abilities, peritoneal fibrosis and apoptosis, mesothelial-to-mesenchymal transition, angiogenesis and chemoresistance. The present review focuses on previous studies addressing the exosome-dependent molecular transfer in peritoneal dissemination in gastric cancer and the potential clinical applications.

Abstract
Peritoneal dissemination is diagnosed in 10–25 % of colorectal cancer patients. Selected patients are treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. For these patients, earlier diagnosis, optimised selection criteria and a personalised approach are warranted. Biomarkers could play a crucial role here. However, little is known about possible candidates. Considering tumour cell adhesion as a key step in peritoneal dissemination, we aim to provide an overview of the functional importance of adhesion molecules in peritoneal dissemination and discuss the prognostic, diagnostic and therapeutic options of these candidate biomarkers. A systematic literature search was conducted according to the PRISMA guidelines. In 132 in vitro, ex vivo and in vivo studies published between 1995 and 2013, we identified twelve possibly relevant adhesion molecules in various cancers that disseminate peritoneally. The most studied molecules in tumour cell adhesion are integrin α2β1, CD44 s and MUC16. Furthermore, L1CAM, EpCAM, MUC1, sLex and Lex, chemokine receptors, Betaig-H3 and uPAR might be of clinical importance. ICAM1 was found to be less relevant in tumour cell adhesion in the context of peritoneal metastases. Based on currently available data, sLea and MUC16 are the most promising prognostic biomarkers for colorectal peritoneal metastases that may help improve patient selection. Different adhesion molecules appear expressed in haematogenous and transcoelomic spread, indicating two different attachment processes. However, our extensive assessment of available literature reveals that knowledge on metastasis-specific genes and their possible candidates is far from complete.

Abstract
PURPOSE Peritoneal carcinomatosis, often associated with malignant ascites, is the most frequent cause of death in patients with advanced gastric cancer. We previously showed that the CXCR4/CXCL12 axis is involved in the development of peritoneal carcinomatosis from gastric cancer. Here, we investigated whether epidermal growth factor receptor (EGFR) ligands are also involved in the development of peritoneal carcinomatosis from gastric cancer. EXPERIMENTAL DESIGN The functional involvement of expression of the ErbB family of receptors and/or EGFR ligands was examined in CXCR4-expressing human gastric cancer cells and fibroblasts, clinical samples (primary tumors and ascites), and an animal model. RESULTS High concentration of the EGFR ligands amphiregulin and heparin-binding EGF-like growth factor (HB-EGF), as well as of CXCL12, were present in malignant ascites. Human gastric cancer cell lines and primary gastric tumors, with high potential to generate peritoneal carcinomatosis, expressed high levels of EGFR and CXCR4 mRNA and protein. Both amphiregulin and HB-EGF enhanced the proliferation, migration, and functional CXCR4 expression in highly CXCR4-expressing gastric cancer NUGC4 cells. Amphiregulin strongly enhanced the proliferation of NUGC4 cells, whereas HB-EGF markedly induced the migration of fibroblasts. Moreover, HB-EGF and CXCL12 together enhanced TNFα-converting enzyme (TACE)-dependent amphiregulin shedding from NUGC4 cells. In an experimental peritoneal carcinomatosis model in mice, cetuximab effectively reduced tumor growth and ascites formation. CONCLUSIONS Our results strongly suggest that the EGFR ligands amphiregulin and HB-EGF play an important role, interacting with the CXCL12/CXCR4 axis, in the development of peritoneal carcinomatosis from gastric cancer, indicating that these two axes may be potential therapeutic targets for peritoneal carcinomatosis of gastric carcinoma.

Abstract
We previously reported that the adhesion of gastric carcinoma cells to the peritoneum mediated by the alpha3beta1 integrin-laminin interaction is a key step in the initial process of peritoneal metastatic dissemination. Carcinoma cells subsequently invade through the intercellular gaps of mesothelial linings. In this study, we examined the role of the interaction of carcinoma cells with laminin-5, which is a major component of submesothelial basement membranes and serves as a high-affinity ligand for alpha3beta1 integrin, in carcinoma cell invasion. Human gastric carcinoma cell lines (MKN1, GT3TKB, and NUGC-4) adhered in an alpha3beta1 integrin-dependent manner to the extracellular matrix deposited by peritoneal mesothelial cells. An in vitro invasion assay using the Boyden chamber system revealed that MKN1 cell migration through the membranes increased when the membranes were coated with matrices produced by mesothelial cells or with laminin-5-containing Matrigel as compared to Matrigel alone. The cell migration promoted by laminin-5-containing Matrigel was inhibited by the presence of anti-alpha3 integrin antibody. When MKN1 cells were cultured in a laminin-5-coated plate, these cells were promoted to produce matrix metalloproteinase (MMP)-9, as assessed by gelatin zymography, enzyme-linked immunosorbent assay, and reverse transcription-polymerase chain reaction. These results suggest that the production of MMP-9 by MKN1 cells was potentiated by the alpha3beta1 integrin-laminin-5 interaction, which facilitated their invasion via degradation of the matrix.

Abstract
In order to block peritoneal metastasis of pancreatic cancer cells, we have attempted to block the signal transduction pathway involving hyaluronan (HA), Src, phosphoinositide 3-kinase (PI3K) and Akt. We examined the effects of Src, PI3K and Akt inhibitors on pancreatic cancer cell motility, invasion and metastasis. The pancreatic cancer cell line SW1990, known to cause peritoneal metastasis efficiently in nude mice, was used in this study. SW1990 cells were stimulated by HA to induce Akt phosphorylation. Then, the inhibitory effects of PI3K and Src kinase inhibitors were examined. Cell motility and cell migration assays were adopted to assess the cancer cell motility and its migration capability. We also examined the therapeutic efficacies of PI3K inhibitor wortmannin on peritoneal metastasis of SW1990 cells in the nude mouse model. Stimulation of SW1990 cells by HA markedly induced the Src-PI3K-Akt signaling, thus enhancing cancer cell motility and its migration. Significantly, we found that wortmannin could exert marked inhibition of the peritoneal metastasis of SW1990 in nude mice in vivo. These findings indicate that the PI3K-Akt signaling pathway plays an essential role in peritoneal metastasis and PI3K inhibitors such as wortmannin can be novel modalities to prevent peritoneal metastasis of invasive cancers such as pancreatic cancer.

Abstract
Patients with advanced gastric carcinoma, especially peritoneal dissemination, have a poor prognosis even after any treatment. Chemokines are now known to play an important role in cancer growth and metastasis. We recently reported that the chemokine CXCL12 plays an important role in the development of peritoneal carcinomatosis from gastric carcinoma. In this study, we investigated signalling pathway involved in the peritoneal carcinomatosis induced by chemokine CXCL12. Akt was rapidly and strongly phosphorylated by chemokine CXCL12. CXCL12 also induced the activation of p70S6K (S6K) and eukaryotic initiation factor 4E binding protein 1 (4E-BP1) included in mammalian target of rapamycin (mTOR) pathways which are located downstream of Akt, resulting in enhancements of metastatic properties such as MMP production, cell migration and cell growth in peritoneal disseminated gastric cancer, NUGC4 cells. Furthermore, mTOR inhibitor rapamycin not only drastically inhibited migration and MMP production, but also induced type II programmed cell death, autophagic cell death. In the present study, we have shown for the first time that the mTOR pathway plays a central role in the development of peritoneal carcinomatosis, and blocking this pathway induces autophagic cell death in disseminated gastric cancer. Therefore, blocking on the CXCR4/mTOR signalling pathway may be useful for the future development of a more effective therapeutic strategy for gastric cancer involved in peritoneal dissemination.

Abstract
Surgical handling of the peritoneum causes an inflammatory reaction, during which a potentially lethal cocktail of active mediators is produced, including cytokines and growth factors. The aim of this study was to investigate the effects of inflammatory cytokines on the interaction between tumor and mesothelial cells. Tumor cell adhesion to a mesothelial monolayer was assessed after preincubation of the mesothelium with interleukin (IL)-1beta, IL-6, and tumor necrosis factor (TNF)-alpha. Preincubation of the mesothelial monolayer with IL-1beta or TNF-alpha resulted in enhanced tumor cell adhesion of Caco2 and HT29 colon carcinoma cells. The amount of stimulation for the Caco2 cells was between 20% and 40% and for HT29 cells between 30% and 70%. Blocking experiments with anti-IL-1beta and anti-TNF-alpha resulted in significant inhibition of the cytokine-stimulated tumor cell adhesion. The presented results prove that IL-1beta and TNF-alpha are significant stimulating factors in tumor cell adhesion in vitro and may therefore account for tumor recurrence to the peritoneum in vivo.

Abstract
In our previous study, we found that the transforming growth factor (TGF)-beta1 enhanced the metastatic and invasive potential of gastric cancer cells. Proteomics was employed in this study to further illustrate the underlying molecular mechanisms. After two-dimensional electrophoresis, image analysis, spot identification, protein identification and database analysis, three proteins, namely, glutathione-S-transferase-pi (GST-pi), cofilin and heat shock protein 27 (HSP27), were found to be up-regulated in TGF-beta1 treated SGC-7901 cells. The findings were further confirmed by Western blot analysis. These results suggested that GST-pi, cofilin and HSP27 might participate in enhanced invasive potential induced by TGF-beta1.

Abstract
Background Ovarian cancer is characterized by a wide-spread intra-abdominal metastases which represents a major clinical hurdle in the prognosis and management of the disease. A significant proportion of ovarian cancer cells in peritoneal ascites exist as multicellular aggregates or spheroids. We hypothesize that these cellular aggregates or spheroids are invasive with the capacity to survive and implant on the peritoneal surface. This study was designed to elucidate early inherent mechanism(s) of spheroid survival, growth and disaggregation required for peritoneal metastases Methods In this study, we determined the growth pattern and adhesive capacity of ovarian cancer cell lines (HEY and OVHS1) grown as spheroids, using the well established liquid overlay technique, and compared them to a normal ovarian cell line (IOSE29) and cancer cells grown as a monolayer. The proteolytic capacity of these spheroids was compared with cells grown as a monolayer using a gelatin zymography assay to analyze secreted MMP-2/9 in conditioned serum-free medium. The disaggregation of cancer cell line spheroids was determined on extracellular matrices (ECM) such as laminin (LM), fibronectin (FN) and collagen (CI) and the expression of α2, α3, αv, α6 and β1 interin was determined by flow cytometric analysis. Neutralizing antibodies against α2, β1 subunits and α2β1 integrin was used to inhibit disaggregation as well as activation of MMPs in spheroids. Results We demonstrate that ovarian cancer cell lines grown as spheroids can sustain growth for 10 days while the normal ovarian cell line failed to grow beyond 2 days. Compared to cells grown as a monolayer, cancer cells grown as spheroids demonstrated no change in adhesion for up to 4 days, while IOSE29 cells had a 2–4-fold loss of adhesion within 2 days. Cancer cell spheroids disaggregated on extracellular matrices (ECM) and demonstrated enhanced expression of secreted pro-MMP2 as well as activated MMP2/MMP9 with no such activation of MMP's observed in monolayer cells. Flow cytometric analysis demonstrated enhanced expression of α2 and diminution of α6 integrin subunits in spheroids versus monolayer cells. No change in the expression of α3, αv and β1 subunits was evident. Conversely, except for αv integrin, a 1.5–7.5-fold decrease in α2, α3, α6 and β1 integrin subunit expression was observed in IOSE29 cells within 2 days. Neutralizing antibodies against α2, β1 subunits and α2β1 integrin inhibited disaggregation as well as activation of MMPs in spheroids. Conclusion Our results suggest that enhanced expression of α2β1 integrin may influence spheroid disaggregation and proteolysis responsible for the peritoneal dissemination of ovarian carcinoma. This may indicate a new therapeutic target for the suppression of the peritoneal metastasis associated with advanced ovarian carcinomas.

Abstract
We evaluated the effect of a "tailor-made" chemo-gene therapy in scirrhous gastric cancer (SGC)-bearing nude mice. For this tailor-made approach, we first selected gefitinib (epidermal growth factor receptor-tyrosine kinase inhibitor)-sensitive SGC cell lines, and 5/8 cell lines demonstrated various degrees of gefitinib-sensitivity. In the highly gefitinib-sensitive NUGC-4, the biological response to NK4 (HGF antagonist/angiogenesis inhibitor) was examined. Subsequently, the composition of an NK4-expressing ternary complex (cationic lipid/nucleic acid/HMG-1, 2 protein) was optimized for maximum transfection activity in NUGC-4. Finally, mice were peritoneally coinoculated with NUGC-4 and scirrhous-associated gastric fibroblasts, NF22, on day 0. Animal models were orally administrated gefitinib (50 mg/kg/day, on days 7-28), and peritoneally NK4-expressing ternary complex (on days 14, 21 and 28). NK4-expression suppressed the gefitinib-resistance induced by the interaction between fibroblasts and SGC, and eventually, this tailor-made combination synergistically decelerated the disease progression by inhibiting proliferative, angiogenic and antiapoptotic effects in tumor tissues. On day 28, both the hemoglobin concentration (g/dl) (control (n = 8), 11.9; treated (n = 8), 17.3; p = 0.0014) and the numbers of mice in good condition (control, 2; treated, 8; p = 0.0012) were significantly greater, and the abdominal girth (mm) (control, 81.1; treated, 70.3; p = 0.0036) was significantly reduced. The median points of bloody ascite-free survival time (days) (control, 22; treated, 44; p < 0.0001) and time to euthanasia (days) (control, 36.5; treated, 56; p < 0.0001) were also significantly prolonged. This combination is a potentially useful approach to the treatment of peritoneal gefitinib-sensitive SGC dissemination.

Abstract
We recently established a mouse model of peritoneal dissemination of human gastric carcinoma, including the formation of ascites, by orthotopic transplantation of cultured gastric carcinoma cells. To clarify the processes of expansion of the tumors in this model, nude mice were sacrificed and autopsied at different points of time after the orthotopic transplantation of the cancer cells for macroscopic and histopathologic examination of the tumors. The cancer cells grew actively in the gastric submucosa and invaded the deeper layers to reach the serosal plane. The tumor cells then underwent exfoliation and became free followed by the formation of metastatic lesions initially in the greater omentum and subsequent colonization and proliferation of the tumors on the peritoneum. Although this model allowed the detection of even minute metastases, it was not satisfactory from the viewpoint of quantitative and objective evaluation. To resolve these problems, we introduced a luciferase gene into this tumor cell line with a high metastasizing potential and carried out in vivo photon counting analysis. This photon counting technique was found to allow objective and quantitative evaluation of the progression of peritoneal dissemination on a real-time basis. This animal metastatic model is useful for monitoring the responses of tumors to anticancer agents.

Abstract
Although cervical adenocarcinoma constitutes approximately 10-20% of primary malignant tumors of the uterine cervix, its pathogenesis is less well understood than that of the corresponding squamous cancer. CD44 is a cell surface glycoprotein postulated to play a role in many biologic processes including tumor growth and metastasis. We have previously reported from immunohistochemical studies that a particular CD44 variant (CD44v5) is consistently overexpressed in endocervical neoplasia. It thus has potential as a diagnostic marker and even as a target for therapeutic approaches directed against specific epitopes. The aim of this study was to investigate which cytokines and hormones are capable of modulating CD44v5 expression, using a cell culture model. The effects of interleukin (IL)-1alpha, IL-1beta, IL-4, IL-13, transforming growth factor (TGF)-beta1, estrogen, and progestogen on CD44v5 expression were examined in cultures of three human cervical adenocarcinoma cell lines (HeLa, HeLa229, and HS588T). Expression was assessed using dual fluorescence-labeled flow cytometry and western blotting techniques. It was found that incubation of cultures for 72 h with IL-1alpha, IL-1beta, IL-4, IL-13, TGF-beta1 (all at 0.1-10 ng/mL), estrogen (5-10 ng/mL), or progestogen (5-20 ng/mL) induced significant upregulation of CD44v5. These factors are likely to exert a similar stimulatory influence in vivo and may contribute to the process of carcinogenesis.

Abstract
Peritoneal carcinomatosis is a frequent cause of death in patients with advanced gastric carcinoma. Because chemokines are now considered to play an important role in the metastasis of various malignancies, we hypothesized that they may be involved in the development of peritoneal carcinomatosis by gastric carcinoma. Human gastric carcinoma cell lines, which were all highly efficient in generating malignant ascites in nude mice upon i.p. inoculation, selectively expressed CXCR4 mRNA and protein. In particular, NUGC4 cells expressed CXCR4 mRNA at high levels and showed vigorous migratory responses to its ligand CXCL12. CXCL12 enhanced proliferation and rapid increases in phosphorylation of protein kinase B/Akt and extracellular signal-regulated kinase of NUGC4 cells. We also showed that AMD3100 (a specific CXCR4 antagonist) effectively reduced tumor growth and ascitic fluid formation in nude mice inoculated with NUGC4 cells. Additionally, we examined human clinical samples. Malignant ascitic fluids from patients with peritoneal carcinomatosis contained high concentrations of CXCL12 (4.67 ng/mL). Moreover, immunohistochemical analysis showed that 22 of 33 primary gastric tumors with peritoneal metastasis were positive for CXCR4 expression (67%), whereas only 4 of 16 with other distant metastasis were positive (25%). Notably, 22 of 26 CXCR4-expressing primary tumors developed peritoneal metastases (85%). CXCR4 positivity of primary gastric carcinomas significantly correlated with the development of peritoneal carcinomatosis (P < 0.001). Collectively, our results strongly suggest that the CXCR4/CXC12 axis plays an important role in the development of peritoneal carcinomatosis from gastric carcinoma. Thus, CXCR4 may be a potential therapeutic target for peritoneal carcinomatosis of gastric carcinoma.

Abstract
BACKGROUND AND AIMS Intraperitoneal tumor cell adhesion to extracellular matrix and to mesothelial cells mediated by integrins is an important step in developing peritoneal carcinosis. In former animal studies, we could demonstrate that intraperitoneal treatment with a new phospholipid (PL) emulsion significantly reduces the amount of peritoneal carcinosis by adhesion prevention. This in vitro study tries to elucidate the influence of phospholipids on cells of the human gastric cancer cell line (NUGC-4) and the human rectal cancer cell line (HRT-18) adhering to mesothelial cells (HOMC) in a monolayer culture in vitro. MATERIALS AND METHODS HOMC cells were derived from omentum majus from patients undergoing elective abdominal surgery. Three passages of both cancer cell lines (NUGC-4 and HRT-18) were used. 1x10(5)/100 microl (HRT-18) or 1.2x10(5)/100 microl (NUGC-4) cells, according to forgoing dilution series, were pretreated with different concentrations of phospholipid emulsion (0.05, 0.1, 0.5, 0.75, 1% PL) stained with cell tracker chloromethyl-benzamidodialkylcarbocyanine (CM-DIL) and seeded into each well on the mesothelial monolayer. After 90 min, the number of adherent cells was counted by fluorescence microscopy at 530 and 620 nm. Additionally, flow cytometric analysis of integrin alpha3 and beta1 expression on the tumor cell surface after treatment with phospholipids was completed. RESULTS We found a dose dependent effect of phospholipids on both tumor cell lines causing a reduction of cell-cell adhesion. Already low concentrations of phospholipids (PL 0.5) had a significant influence. The mean cell count could be reduced from 234+/-12/mm2 in controls to 124+/-41/mm2 (PL 0.5; NUG-4) and from 295+/-49/mm2 to 169+/-29/mm2 (PL 0.5; HRT-18), respectively. Additionally, the integrin alpha3 and beta1 expression on both cell lines could be reduced. CONCLUSION Our results within the scope of published data indicate that adhesion prevention is capable to reduce peritoneal carcinosis.

Abstract
Transforming growth factor-beta (TGF-beta), a multifunctional cytokine, exerts contradictory roles in different kinds of cells. A number of studies have revealed its involvement in the progression of many types of tumors. To investigate the effect of TGF-beta on gastric carcinoma, SGC7901, BGC823 and MKN28 (a TGF-beta-resistant cell line) adenocarcinoma clones were used. After pretreatment in serum-free medium with or without 10 ng/ml TGF-beta1, their experimental metastatic potential, chemotaxis, and invasive and adhesive ability were measured. Furthermore, zymography for gelatinase was processed. Liver colonies were also measured 4 weeks after inoculation of SGC7901, BGC823 and MKN28 in Balb/c nude mice, and an increase in the number of surface liver metastases was seen in SGC7901 (from 11.0+/-3.0 to 53.3+/-3.3) and BGC823 (from 9.3+/-2.5 to 60.0+/-2.8) groups, whereas there was no difference between MKN28 groups (from 35.2+/-3.8 to 38.5+/-2.7). In vitro experiments showed that TGF-beta1 increased the adhesion capacity of SGC7901 and BGC823 cells to immobilized reconstituted basement membrane/fibronectin matrices and promoted their penetration through reconstituted basement membrane barriers. Zymography demonstrated that enhanced invasive potential was partly due to the increased type IV collagenolytic (gelatinolytic) activity, but there was no difference in type IV collagenolytic activity and other biological behaviors between MKN28 groups. These results suggested that TGF-beta1 might modulate the metastatic potential of gastric cancer cells by promoting their ability to break down and penetrate basement membrane barriers and their adhesive and motile activities. We speculated that TGF-beta1 might act as a progression-enhancing factor in gastric cancer. Therefore blockage of TGF-beta or TGF-beta signaling might prevent gastric cancer cells from invading and metastasizing.

Abstract
BACKGROUND In gastric cancer, the management of peritoneal dissemination in the Peritoneal cavity is extremely important; however, peritoneal dissemination in the final stage of gastric cancer remains untreatable. Peritoneal dissemination involves several steps, including tumor-cell attachment, invasion, and growth in the peritoneum. Many cytokines, growth factors, matrix metalloproteinases (MMPs), and angiogenic factors play important roles in these steps. So far, few studies have investigated the correlation, if any, between peritoneal dissemination and the angiogenic factor, vascular endothelial growth factor (VEGF). METHODS Immunohistochemical staining, using the avidin-biotin peroxidase complex method, was performed on slides of surgical specimens from 40 patients with stage II gastric cancer with serosal invasion, who underwent surgery at our hospital between 1990 and 2000. Anti-human VEGF rabbit polyclonal IgG was used as the primary antibody. VEGF expression was classified in one of four categories depending on the percentage of tumor-cell staining (P). VEGF expression was also classified in one of three categories depending on the staining intensity (I). The VEGF expression score was calculated as P x I. RESULTS There were ten patients with peritoneal recurrence. Of these, seven had macroscopic type-4 scirrhous-type gastric carcinoma. In the immunohistochemical study, the VEGF score of patients with peritoneal recurrence was 9.40 +/- 2.46; on the other hand, that of patients without peritoneal recurrence was 3.47 +/- 2.36. The VEGF score of patients with peritoneal recurrence was significantly higher than that of patients without peritoneal recurrence. In patients with macroscopic type 4, the VEGF score of those with peritoneal recurrence was 9.14 +/- 2.19, while on the other hand, that of the patients without peritoneal recurrence was 3.80 +/- 3.03. The VEGF score of these patients with peritoneal recurrence was significantly higher than that of those without peritoneal recurrence. The survival rate in the VEGF low-expression group was significantly higher than that in the VEGF high-expression group. Multivariate analysis showed that the VEGF score was a significant parameter of peritoneal recurrence. CONCLUSION These results suggested that VEGF was correlated with peritoneal metastasis from gastric cancer, and that VEGF was a useful indicator of peritoneal recurrence.

Abstract
Adhesion of tumor cells to mesothelial cells or extracellular matrix components is a pivotal step in developing peritoneal dissemination after gastric cancer. As phospholipids were found to reduce adhesion formation, especially at sites of peritoneal lesions, we assessed the inhibition of attachment of NUGC-4 gastric cancer cells by local treatment with phospholipids to the peritoneum in nude mice. Gastric cancer cells (1xl0(6)) suspended in either normal saline (controls) or phospholipid suspension 75 mg/kg body weight (PL75) or 150 mg/kg (PL150) were injected intraperitoneally into 90 female BALB/c nu/nu mice. The treatment groups were subdivided into animals with defined peritoneal lesions and animals without lesions. After 30 days the extent of peritoneal carcinosis and the Peritoneal Cancer Index were evaluated. Statistical analysis was performed with two factorial ANOVAs. The level of significance was adjusted according to Bonferrorni (alpha = 0.00278). During a 90-day observation period the survival rate was determined using the log rank test. After 30 days the intraperitoneal tumor volume was reduced by PL150 up to 0.6 ml (SEM 0.16) and 0.48 ml (SEM 0.09) in mice with peritoneal lesions compared to 0.9 ml (SEM 0.2) and 0.9 ml (SEM 0.1) in the control group (P = 0.04). The mean area of tumor adhesion amounted to 145 mm(2) (SEM 17) (P = 0.08) and 164 mm(2) (SEM 32.8) (P = 0.049) with peritoneal lesions after treatment with PL150 [controls: 216 mm(2) (SEM 28.5) and 245 mm(2) (SEM 29.3)]. The peritoneal cancer index was 16.4 (SEM 1.7) in the control group and 9 (SEM 1.68) with PL150 (P = 0.0002). In the subgroup with peritoneal lesions, the respective values were as follows: controls: 20.8 (SEM 0.85); PL 150:14.3 (SEM 1.07) (P = 0.0001). We found a prolonged survival rate after treatment with PL150. However, this effect was not significantly different to that seen in the control group. Treatment with PL75 had no significant influence. Phospholipids may be an efficacious and economic tool for reducing peritoneal tumor cell adhesion and consequently the development of peritoneal carcinosis after resection of gastric cancer.

Abstract
Mesothelial cell intercellular adhesion molecule-1 (ICAM-1) has recently been shown to play a role in tumour cell adherence to the peritoneum. However, solid tumours poorly express its most ubiquitous ligand, beta2 integrin. The aim of this study was to investigate the role of the beta2 integrin subunit and CD43, a known ligand for ICAM-1, in the development of peritoneal metastases. beta2 Integrin subunit and CD43 expression was assessed on a number of tumour cell lines. Adhesion of SW1222 and PSN-1 cells to human peritoneal mesothelial cells was investigated using a fluorometric assay incorporating an inhibitory antibody to beta2 integrin and CD43. beta2 Integrin expression was not inducible on these tumour cell lines, but Western blotting demonstrated CD43 expression in all the cancer cell lines examined and cell surface expression was confirmed by flow cytometry. The anti-CD43 antibody significantly reduced adhesion of PSN-1 and SW1222 cells to HPMC, however beta2 integrin inhibition did not reduce tumour cell adhesion. CD43 is expressed by a variety of carcinoma cell lines, and plays a role in tumour cell-peritoneal adhesion probably via interactions with its putative ligand ICAM-1.

Abstract
Background Nidation of floating tumour cells initiates peritoneal carcinosis and limits prognosis of gastro-intestinal tumours. Adhesion of tumour cells to extracellular matrix components is a pivotal step in developing peritoneal dissemination of intraabdominal malignancies. Since phospholipids efficaciously prevented peritoneal adhesion formation in numerous animal studies we investigated their capacity to reduce adhesions of gastric cancer cells to extracellular matrix components (ECM). Methods Human gastric cancer cells (NUGC-4, Japanese Cancer Research Resources Bank, Tokyo, Japan) were used in this study. Microtiter plates were coated with collagen IV (coll), laminin (ln) and fibronectin (fn). Non-specific protein binding of the coated wells was blocked by adding 1% (w/v) BSA (4°C, 12 h) and rinsing the wells with Hepes buffer. 50.000 tumour cells in 100 μl medium were seeded into each well. Beside the controls, phospholipids were added in concentrations of 0.05, 0.1, 0.5, 0.75 and 1.0/100 μl medium. After an incubation interval of 30 min, attached cells were fixed and stained with 0.1% (w/v) crystal violet. The dye was resuspended with 50 μl of 0.2% (v/v) Triton X-100 per well and colour yields were then measured by an ELISA reader at 590 nm. Optical density (OD) showed a linear relationship to the amount of cells and was corrected for dying of BSA/polystyrene without cells. Results The attachment of gastric cancer cells to collagen IV, laminin, and fibronectin could be significantly reduced up to 53% by phospholipid concentrations of 0.5 mg/100 μl and higher. Conclusion These results, within the scope of additional experimental studies on mice and rats which showed a significant reduction of peritoneal carcinosis, demonstrated the capacity of phospholipids in controlling abdominal nidation of tumour cells to ECM components. Lipid emulsions may be a beneficial adjunct in surgery of gastrointestinal malignancies.

Abstract
OBJECTIVE To evaluate the influence of intraperitoneal treatment with phospholipids on the formation of peritoneal carcinosis after inoculation of colonic tumor cells in rats. The presence of tumor cells in the peritoneal cavity serves as a prognostic marker for postoperative survival after resection of gastrointestinal cancer. Intraperitoneal tumor cell attachment is a pivotal step in developing peritoneal carcinosis. Intraabdominal application of phospholipids resulted in a significant decrease of adhesion formation, especially at sites of peritoneal lesions. METHODS 2x10(6) colonic tumor cells (DHD/K12/TRb) were injected intraperitonely in female BD-IX rats. A total of 90 rats were divided into three groups with treatments of phospholipids at 75 mg/kg or 150 mg/kg bodyweight or sodium chloride at 0.9% in the control group. The treatment groups were subdivided into animals with defined peritoneal lesions and animals without lesions. After 30 days, the extent of peritoneal carcinosis was determined by measuring the tumor volume, the area of tumor attachment and the Peritoneal Cancer Index. Over a 90-day observation period, the survival rate was analyzed. In vitro, we examined the reduction of tumor cell adhesion on extracellular matrix components after treatment with phospholipids. Microtiter plates were coated with laminin, fibronectin or collagen IV for adhesion experiments. RESULTS In our study, we found a significant reduction of peritoneal dissemination with respect to all evaluation methods after treatment with phospholipids at 150 mg/kg in animals without peritoneal lesions. This could not be achieved using the lower concentration of phospholipids (75 mg/kg). In vitro, the maximum reductions of tumor cell adhesion by phospholipids compared with the control values for laminin and fibronectin were 46% and 37%, respectively, whereas for collagen IV the reduction was only 24% ( p<0.0001). CONCLUSIONS A new method of prevention of intraperitoneal tumor cell adhesion, possibly leading to a reduced incidence of peritoneal carcinosis after surgery of gastrointestinal tumors, is introduced.

Abstract
The interaction between gastric carcinoma cells and the peritoneal lining is a key step in peritoneal dissemination. In this study, we examined the roles of the beta1 family of integrin receptors in the adhesion of such cells to the peritoneum. The adhesion of several gastric carcinoma cell lines to peritonea excised from mice was inhibited most by an anti-alpha3 integrin antibody and to a lesser extent by an anti-alpha2 integrin antibody. In the peritoneal implantation of NUGC-4 human gastric carcinoma cells in athymic mice, treatment of the cells with anti-alpha2 or anti-alpha3 integrin antibody reduced the number of disseminated nodules; suppression by the anti-alpha3 integrin antibody was stronger than that by the anti-alpha2 integrin antibody. The cDNAs to human alpha2 and alpha3 integrins were introduced into K562 leukemic cells, which were positive for the integrin beta1 subunit but negative for the alpha2 or alpha3 subunit. The alpha3 integrin-transfected cells adhered to excised peritoneum and to a monolayer of peritoneal mesothelial cells more firmly than did the alpha2 integrin-transfected cells or the mock transfectant. Reverse transcription-PCR was used to analyze the expression of laminin-5 and laminin-10/11, which have been reported to serve as high-affinity ligands for alpha3beta1 integrin. mRNA for these laminin isoforms was found in mesothelial cells from the diaphragm and parietal peritoneum. These results strongly suggest that alpha3beta1 integrin plays an essential role in mediating the initial attachment of cancer cells to the peritoneum, leading to the formation of peritoneal metastasis.

Abstract
The mechanisms underlying progression of peritoneal metastasis by gastric cancer after micrometastasis formation remain unclear. In the present study, we investigated metastasis to the abdominal wall peritoneum, one of the major features of peritoneal spread, using a human gastric cancer cell line (GCIY-EGFP) tagged with the green fluorescence protein gene (GFP). This model allows sensitive, specific and sequential observation of metastasis development from the initial deposits to peritoneal carcinomatosis at the end stage. In the initial phase, GCIY-EGFP cells could form micrometastasis selectively on the omentum and mesenterium in a milky spot-dependent manner, but not on abdominal wall peritoneum lacking milky spots until the late stages. In vitro analysis using primary mesothelial cells revealed addition of TNF-alpha to decrease their stress fibers, leading to morphological change followed by exposure of the submesothelial extracellular matrix (ECM) in intercellular gaps. Such TNF-alpha pretreatment was found to enhance attachment of tumor cells to the mesothelial monolayer. When tumor cells were injected into the peritoneal cavity of TNF-alpha pretreated mice, they could metastasize to the abdominal wall peritoneum from the very early stages, resulting in accelerated accumulation of ascites than in TNF-alpha non-pretreatment controls. RT-PCR analysis revealed that tumor cells express cytokines and chemokines, including TNF-alpha. Furthermore, TNF-alpha treatment results in up-regulation of expression of monocyte chemoattractant protein-1 (MCP-1) and IL-8 by mesothelial cells and of TNF-alpha itself by inflammatory leukocytes in the peritoneal cavity. These results suggest that metastasis to the abdominal wall peritoneum occurs as a second step from the first omental metastasis in a milky spot-independent manner and that TNF-alpha derived from tumor cells, mesothelial cells and inflammatory leukocytes in the peritoneal cavity may be involved in the progression of peritoneal metastasis.

Abstract
Although peritoneal metastasis is an important factor determining the prognosis of patients with gastrointestinal cancer, the mechanisms have not yet been clearly defined. Human peritoneal mesothelial cells (HPMC) are the first line against disseminated tumor cells. Recent reports have shown that mesothelial cells are capable of secreting various cytokines and growth factors. In this study, we isolated human mesothelial cells from surgically resected omental tissue and examined the production and interaction of two major angiogenic factors, vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (FGF-2). Quiescent HPMC produced a considerable amount of VEGF at almost the same level as tumor cells. Interestingly, addition of FGF-2 to the culture significantly increased the mRNA synthesis and protein secretion of VEGF in a dose-dependent manner, as determined by Northern blot and ELISA. The addition of 0.5 ng/mL FGF-2 was enough to stimulate VEGF production, and the effect reached a plateau at 5 ng/mL. Reverse-transcribed polymerase chain reaction (RT-PCR) method clarified that the HPMC-derived VEGF consisted mostly of VEGF(121) and VEGF(165), which are both predominantly soluble forms. These data suggest that HPMC contribute to the development of metastases and the accumulation of malignant ascites due to the production of VEGF, especially in cancers that do not express enough amount of VEGF.

Abstract
The processes of ovarian cancer dissemination are characterized by altered local proteolysis, cellular proliferation, cell attachment, and invasion, suggesting that the urokinase-type plasminogen activator (uPA) and its specific inhibitor (plasminogen activator inhibitor type-1 (PAI-1)) could be involved in the pathogenesis of peritoneal dissemination. We showed previously that expression of uPA and PAI-1 in the human ovarian cancer cell line HRA can be down-regulated by exogenous bikunin (bik), a Kunitz-type protease inhibitor, via suppression of transforming growth factor-beta1 (TGF-beta1) up-regulation and that overexpression of the bik gene can specifically suppress the in vivo growth and peritoneal dissemination of HRA cells in an animal model. We hypothesize that the plasminogen activator system in mesothelial cells can be modulated by HRA cells. To test this hypothesis, we used complementary techniques in mesothelial cells to determine whether uPA and PAI-1 expression are altered by exposure to culture media conditioned by HRA cells. Here we show the following: 1) that expression of PAI-1, but not uPA, was markedly induced by culture media conditioned by wild-type HRA cells but not by bik transfected clones; 2) that by antibody neutralization the effect appeared to be mediated by HRA cell-derived TGF-beta1; 3) that exogenous TGF-beta1 specifically enhanced PAI-1 up-regulation at the mRNA and protein level in mesothelial cells in a time- and concentration-dependent manner, mainly through MAPK-dependent activation mechanism; and 4) that mesothelial cell-derived PAI-1 may promote tumor invasion possibly by enhancing cell-cell interaction. This represents a novel pathway by which tumor cells can regulate the plasminogen activator system-dependent cellular responses in mesothelial cells that may contribute to formation of peritoneal dissemination of ovarian cancer.

Abstract
The anti-tumor effect of N- [3,4-dimethoxycinnamoyl] -anthranilic acid (tranilast) was examined in experimental pancreatic cancer. Proliferation of PGHAM-1 cells was inhibited by tranilast in a dose-dependent manner, showing a significant difference at a concentration of 25 microgram/ml (p<0.05). In colony formation, tranilast reduced the number of colonies at a concentration of 25 microgram/ml (p<0.01). DNA synthesis for 12 hours was attenuated dose-dependently and a significant difference was observed at concentrations of greater than 50 microgram/ml (p<0.05). From cell cycle analysis, a dose-dependent increase in the distribution of G0-G1 phase was observed. In the dorsal air sac model, the mean angiogenesis indices in PGHAM-1 chambers were 4.17 +/- 0.22 (control group) and 2.33 +/- 0.84 (treatment group), and in VEGF chambers they were 3.60 +/- 0.67 (control group) and 1.92 +/- 0.42 (treatment group), In the peritoneal dissemination model, the quantity of sanguineous ascites, the number and the size of diaphragmatic nodules and the microvessel density (MVD) of the metastatic site were reduced by tranilast significantly. In conclusion, the anti-tumor effect of tranilast on proliferation and on tumor-angiogenesis was confirmed in experimental pancreatic cancer.

Abstract
INTRODUCTION Recently, several mice models have been used for investigating cancer metastasis. However, there are no metastatic and peritoneal dominated variants from the same parental cell line. AIM AND METHODOLOGY To elucidate the mechanisms of metastasis, we established highly liver metastatic and peritoneal disseminated models in nude mice, and then characterized several factors related to metastasis in these cells. We established a series of well-characterized sublines that showed metastatic potentials to different organ sites of nude mice. Two sublines were selected sequentially from the parental pancreatic cancer cell line, HPC-4, resulting in a highly liver metastatic cell line, HPC-4H4, and a highly peritoneal disseminated cell line, HPC-4P4a. Using these three cell lines, we investigated several biologic properties and mRNA levels of differentially expressed genes involved in cancer metastasis. RESULTS The tumorigenicity, the motile activity, and the adhesive activity of metastatic sublines were higher than those of parental HPC-4 cells. Macroscopic and microscopic findings and the DNA ploidy pattern were the same among the three cell lines. In addition, HPC-4H4 cells expressed clearly higher levels of vascular endothelial growth factor and IL-8 expression than did HPC-4P4a cells. In fluorescence-activated cell sorter analysis of adhesion molecules, the expression of integrin-alpha2 was enhanced in HPC-4 cells, integrin-alphavbeta5 was enhanced in HPC-4H4 cells, and integrin-alpha3 was enhanced in HPC-4P4a cells. Osteopontin, vascular endothelial growth factor, and hepatocyte growth factor were among the genes that were upregulated in HPC-4H4 cells compared with HPC-4P4a cells. HPC-4P4a cells did not metastasize to the liver by intrasplenic injection. Conversely, HPC-4H4 cells metastasized remarkably to the peritoneum by intraabdominal injection. CONCLUSION These sublines are the first reported liver metastatic and peritoneal disseminated models derived from the same parental cell lines. The results of our study suggest that the process of hematogenous metastasis is not the same as that of peritoneal dissemination.

Abstract
Homeobox genes regulate sets of genes that determine cellular fates in embryonic morphogenesis and maintenance of adult tissue architecture by regulating cellular motility and cell-cell interactions. Our previous studies showed that a specific member, HOXD3, when overexpressed, upregulates integrin beta3 expression in human erythroleukemia HEL cells and lung cancer A549 cells, and enhances their motility and invasiveness. We performed a microarray study of over 7075 genes to determine the mechanisms underlying the HOXD3-enhanced motility and invasiveness in A549 cells. RT-PCR-based tracking gene analyses highlighted a set of TGF-beta-upregulated genes, which included matrix metalloproteinase-2, syndecan-1, CD44, and TGF-beta-induced 68 kDa protein. Exogenous TGF-beta also caused this pattern of upregulation in A549 cells and enhanced their migratory and invasive activity, confirming the involvement of TGF-beta signaling. However, HOXD3 reduced the expression of TGF-beta-independent genes coding for desmosomal components such as desmoglein, desmoplakin and plakoglobin which are known to suppress tumor invasion and metastasis. These results suggest that HOXD3 enhances the invasive and metastatic potential of cancer cells through the TGF-beta-dependent and -independent pathways.

Abstract
We investigated the effects of transforming growth factor-beta (TGF-beta) on biological behavior of a weakly malignant rat mammary carcinoma ER-1 cell line. TGF-beta enhanced the tumorigenic and metastatic capacity of ER-1 cells and their in vitro invasiveness to rat mesothelial and endothelial cell. Further cell biological analysis indicated that the increased invasive and metastatic capacity of ER-1 cells by TGF-beta was due to the increase in cell motility and adhesion to the mesothelial and endothelial cell monolayers. Thus, it is suggested that TGF-beta acts on ER-1 cells as a progression-enhancing factor which stimulates their adhesive and motile activities.

Abstract
The biological effect of transforming growth factor-beta (TGF-beta) is cell type-specific and complex. The precise role of TGF-beta is not clear in vivo. To elucidate the regulation mechanism of endogenous TGF-beta on hepatoma progression, we modified the MH129F mouse hepatoma cell with a retroviral vector encoding the extracellular region of type II TGF-beta receptor (TRII). Soluble TRII (TRIIs) blocked TGF-beta binding to TRII on the membrane of hepatoma cells. Growth of MH129F cells was inhibited by TGF-beta1 treatment; however, soluble TRII-overexpressing cells (MH129F/TRIIs) did not show any change in proliferation after TGF-beta1 treatment. MH129F/TRIIs cells also increased vascular endothelial growth factor (VEGF) expression, endothelial cell migration, and tube formation. Implantation of MH129F/TRIIs cells into C3H/He mice showed the significantly enhanced tumor formation. According to Western blot and protein kinase C assay, the expression of VEGF, KDR/flk-1 receptor, and endothelial nitric-oxide synthase was enhanced, and the phosphorylation activity of protein kinase C was increased up to 3.7-fold in MH129F/TRIIs tumors. Finally, a PECAM-1-stained intratumoral vessel was shown to be 4.2-fold higher in the MH129F/TRIIs tumor. These results indicate that VEGF expression is up-regulated by a blockade of endogenous TGF-beta signaling in TGF-beta-sensitive hepatoma cells and then stimulates angiogenesis and tumorigenicity. Therefore, we suggest that endogenous TGF-beta is a major regulator of the VEGF/flk-1-mediated angiogenesis pathway in hepatoma progression.

Abstract
We established a new cell line, NUGC-3P4T, with high peritoneal metastatic disseminating potential in nude mice. NUGC-3P4T cells were derived from the human gastric carcinoma line NUGC-3, which has low capacity for peritoneal dissemination. NUGC-3P4T cells developed peritoneal dissemination in 10 / 10 (100%) mice, whereas the parental NUGC-3 cells developed dissemination in 1 / 5 (20.0%) mice. The metastatic foci in the peritoneum showed essentially the same histological appearance as those induced by parental cells. The tumorigenicity, the motile activity and the adhesive activity to the laminin of NUGC-3P4T cells were stronger than those of NUGC-3 cells. Production of IL-8 was significantly higher in NUGC-3P4T than in NUGC-3. cDNA macroarrays analysis showed that a variety of cytokines, interleukins, and other immunomodulators and their receptors were up- or down-regulated at the mRNA level in NUGC-3P4T cells, compared with NUGC-3 cells. Thus, this unique cell line and in vivo model might be useful to study the biology of peritoneal dissemination of human gastric cancer.

Abstract
In this experimental study, the effect of inflammatory cytokines and growth factors on tumour cell adhesion to the peritoneum was investigated. A reproducible in vitro assay was developed to study the adhesion of CC531 colon carcinoma cells to an autologous monolayer of rat mesothelial cells. Tumour cell adhesion to mesothelium pre-incubated with interleukin-1beta (IL-1beta) and epidermal growth factor (EGF) resulted in at least 60% more tumour cell adhesion at maximal stimulation (p</=0.001). Transforming growth factor-beta (TGF-beta) pre-incubation resulted in minor, though significant stimulation of cell adhesion (maximal 16%, p<0.05). The effect of IL-1beta was time- and dose-dependent. No mesothelial cell proliferation took place after pretreatment with IL-1beta, indicating that enhanced adhesion was not based on an increase in the number of mesothelial cells. Pretreatment with EGF stimulated mesothelial cell growth as measured by DNA analysis. This effect on cell growth and adhesion was dose-dependent. Additional blocking experiments with anti-IL-1beta resulted in statistically significant inhibition of IL-1beta-stimulated tumour cell adhesion (p</=0.01), demonstrating the specificity of this effect. Interferon-gamma (IFN-gamma), tumour necrosis factor-alpha (TNF-alpha), IL-6, and insulin-like growth factor (IGF-I) pre-incubation had no effect on tumour cell adhesion. These results prove that IL-1beta and EGF are significant promoting factors in tumour cell adhesion to mesothelium in vitro and may therefore account for tumour recurrence in the peritoneum in vivo.

Abstract
A new ex vivo method for assaying adhesion of cancer cells to the greater omentum has been developed using mouse greater omentum and [3H]labelled human gastric and mouse colorectal cancer cells. Since the adhesion rates were found to increase up to 18 h and labelled cells seemed to be stable during the period, the present method could be useful for investigating adhesion of cancer cells to the greater omentum, which must occur at the first step of the peritoneal dissemination. The adhesion of cancer cells to the greater omentum was inhibited by a series of chemically synthesized oligosaccharides and Gal beta1,3[3OMeGal beta1,4GlcNAc beta1,6]alphaBn was found to be the best inhibitor. The anti-tumor effect of this novel tetrasaccharide in vivo was shown in preliminary experiments using Balb/c mice and colon26 cells.

Abstract
We established peritoneal dissemination-prone subcultures (PCI-43p3) using nude mice by a repetitive in vivo selection of intraperitoneally inoculated PCI-43, a pancreas adenocarcinoma cell line. The subcultures showed upregulated expression of matrix metalloproteinase (MMP)-9, but not MMP-2 in culture supernatants. They also produced increased amounts of vascular endothelial growth factor (VEGF), which was not associated with alterations in isoforms of VEGF mRNA. PCI-43p3 cells attached to cultured mesothelial cell monolayers more readily than did the parent PCI-43 cells. The angiogenesis inhibiting agent, TNP-470, at 30 mg / kg was administered to the model mice, resulting in a prominent suppression of the establishment of peritoneal nodules. The suppression was dependent on the duration of TNP-470 treatment. TNP-470 treatment significantly suppressed proliferation of tumor cells in disseminated nodules, assessed in terms of immunostaining for proliferating cell nuclear antigen (PCNA). TNP-470 did not affect the in vitro attachment between PCI-43p3 and mesothelial cells. The combined data show that anti-angiogenic treatment profoundly suppresses the in vivo process of peritoneal dissemination.

Abstract
The present study was designed to clarify the molecules responsible for peritoneal dissemination of cancer cells. We established sublines with high (HP cells) and low (LP cells) passing activity through the membrane of a transwell chamber. The cell lines were established from the human pancreatic cancer cell line, Panc-1. LP cells demonstrated an octagonal shape and tight adhesion, whereas HP cells exhibited a spindle shape and grew with less cell-cell contact in vitro. It was found that HP cells demonstrated a high degree of peritoneal dissemination in nude mice following peritoneal injection of these cells compared to LP cells. We subsequently investigated the expression of certain adhesion molecules. Consequently, we found that LP cells exhibited a stronger expression of E-cadherin than HP cells. On the other hand, there was no difference in the expression of CD44H and beta1 integrin between these two sublines. Passing activity of LP cells through the membrane of the invasion chamber increased to nearly equal levels with HP cells following treatment with anti-human E-cadherin antibody. Moreover, transfection of mouse E-cadherin cDNA into HP cells reduced both passing activity through the membrane of the invasion chamber and peritoneal dissemination in nude mice to levels similar to that of LP cells. In conclusion, these results indicated that loss of E-cadherin facilitates both passing activity in an invasion chamber and peritoneal dissemination, playing a causative role in peritoneal dissemination of cancer cells.

Abstract
We established a new cell line, AZ-P7a, with high peritoneal-metastatic potential in nude mice. AZ-P7a cells were derived from the human gastric carcinoma line AZ-521, which has low capacity for peritoneal dissemination. AZ-P7a cells developed peritoneal metastasis in 11 / 14 (78.6%) mice, whereas the parental AZ-521 cells developed metastasis in 2 / 6 (33.3%) mice. The metastatic foci in the peritoneum showed essentially the same histological appearance as those induced by parental cells. The tumorigenicity and the motile activity of AZ-P7a cells were stronger than those of the parental AZ-521 cells; in contrast, adhesion to the extracellular matrix and the production of vascular endothelial growth factor by AZ-P7a cells were decreased. In fluorescence-activated cell sorter (FACS) analysis, AZ-P7a cells expressed significantly greater levels of integrins alpha2, alpha3, alpha5, alpha6 and alphavbeta5, as compared with AZ-521 cells. However, alpha1, alpha4, alphavbeta3, hCD44H, hCD44v3, hCD44v6 and hCD44v10 were not expressed in either cell line. AZ-P7a cells developed no liver metastasis when administered by the intrasplenic injection method, though the highly liver metastatic cell line AZ-H5c showed the same rate of peritoneal dissemination as that exhibited by AZ-P7a cells after intraabdominal injection. These findings suggested that the mechanism of peritoneal dissemination differed from that of hematogenous metastasis. Moreover, the latter appears to be controlled by more complex mechanisms than the former. Thus, this cell line might be useful for investigating the mechanism of peritoneal dissemination of human gastric cancer.

Abstract
Prostate cancers (PRCAs) frequently metastasize to bone. We show here that this process is facilitated by osteoblast-mediated tumor cell recruitment. Transforming growth factor-beta1 (TGF-beta1) is produced by osteoblasts in a latent form and is activated by proteases in a cell-dependent manner. This cytokine exhibits pleiotropic effects on cell-extracellular matrix (ECM) interactions and may influence tumor cell invasion and metastasis. Our purpose was to identify the potential molecular mechanisms involved in osteoblast-mediated cell recruitment and to characterize the effect of TGF-beta1 on adhesion, motility and invasiveness of a human prostate cancer cell line with high bone metastatic potential (PC3 cell line) in vitro. Conditioned media from osteoblast cultures (OB CM) enhanced PC3 cell chemotaxis and invasion of reconstituted basement membrane. These effects were blocked by a neutralizing TGF-beta1 polyclonal antibody but not by elution of the OB CM in agarose-heparin columns, suggesting that TGF-beta1, but not EGF-like proteins, contribute to PC3 cell recruitment. In addition, TGF-beta1 directly induced chemotaxis and invasion of PC3 cells in a dose-dependent manner. The TGF-beta1-mediated invasion and motility were accompanied by increased PC3 cell adhesion, spreading and alpha2beta1 and alpha3beta1 integrin expression. These events are involved in the cell adhesion to several components of basement membrane and ECM and in the selective invasion of metastatic tumor cells. Our results suggest that TGF-beta1 can influence cellular recognition of ECM components by prostatic cancer cells and can modulate cell adhesion and invasion leading to increased invasive potential. Given the widespread tissue distribution of TGF-beta1, and the high levels present in the bone, this cytokine may be an important autocrine-paracrine modulator of the bone invasive phenotype in vivo.

Abstract
BACKGROUND Prediction of peritoneal dissemination is very difficult using current diagnostic tools such as computed tomography, ultrasonography, or various tumor markers. The predictive value of serum CA 125 levels for peritoneal metastasis from gastric carcinoma was studied. METHODS The sera from 384 patients with gastric carcinoma were measured for CA 125 titer using an immunoradiometric assay. Carcinoembryonic antigen, carbohydrate antigen 19-9, and sialyl-Tn antigen were measured in the same samples. RESULTS The serum CA 125 level was elevated according to the degree of peritoneal dissemination. The reference value for peritoneal dissemination was determined to be 35 U/mL, resulting in a sensitivity of 39.4%, specificity of 95.7%, and diagnostic accuracy of 90.8%. The diagnostic ability was more reliable than the other imaging modalities including computed tomography and ultrasonography and the other useful tumor markers for gastric carcinoma. The serum CA 125 level was elevated after gastrectomy for approximately 2 months, most likely due to the continuous inflammation of the peritoneum and lost predictive significance for peritoneal dissemination during this period. CONCLUSIONS Measurement of the serum CA 125 titer may be a powerful predictor of peritoneal metastases in patients with gastric carcinoma.

Abstract
A retrospective study of 50 patients with scirrhous carcinoma of the stomach who had undergone surgery was performed to elucidate whether immunohistochemical overexpression of transforming growth factor-beta1 (TGF-beta1) could predict the patients' survival. To evaluate the proliferative activity of the tumor, the proliferating cell nuclear antigen (PCNA) index was used. Expression of TGF-beta1 was low in 27 patients and high in 23. Clinicopathological characteristics were not significantly different between the two groups with high and low TGF-beta1 expression. Tumors with higher TGF-beta1 expression had higher PCNA indices (p = 0.0467, unpaired Student's t test). The 5-year survival rate was 40.4% for the low TGF-beta1 group and 28.7% for the high TGF-beta1 group (p = 0.0388, log rank test). By multivariate analysis, pT, residual tumor, and TGF-beta1 were the independent prognostic factors. These results suggest that immunohistochemical expression of TGF-beta1 is one of the useful predictors for estimating the patients' survival in scirrhous carcinoma of the stomach particularly of the T3 and T4 stages.
