Abstract
Owing to the increasing incidence and prevalence of inflammatory bowel disease (IBD) worldwide, effective and safe treatments for IBD are urgently needed. Hydrogen sulfide (H2S) is an endogenous gasotransmitter and plays an important role in inflammation. To date, H2S-releasing agents are viewed as potential anti-inflammatory drugs. The slow-releasing H2S donor 5-(4-hydroxyphenyl)-3H-1,2-dithiole-3-thione (ADT-OH), known as a potent therapeutic with chemopreventive and cytoprotective properties, has received attention recently. Here, we reported its anti-inflammatory effects on dextran sodium sulfate (DSS)-induced acute (7 days) and chronic (30 days) colitis. We found that ADT-OH effectively reduced the DSS-colitis clinical score and reversed the inflammation-induced shortening of colon length. Moreover, ADT-OH reduced intestinal inflammation by suppressing the nuclear factor kappa-B pathway. In vivo and in vitro results showed that ADT-OH decreased intestinal permeability by increasing the expression of zonula occludens-1 and occludin and blocking increases in myosin II regulatory light chain phosphorylation and epithelial myosin light chain kinase protein expression levels. In addition, ADT-OH restored intestinal microbiota dysbiosis characterized by the significantly increased abundance of Muribaculaceae and Alistipes and markedly decreased abundance of Helicobacter, Mucispirillum, Parasutterella, and Desulfovibrio. Transplanting ADT-OH-modulated microbiota can alleviate DSS-induced colitis and negatively regulate the expression of local and systemic proinflammatory cytokines. Collectively, ADT-OH is safe without any short-term (5 days) or long-term (30 days) toxicological adverse effects and can be used as an alternative therapeutic agent for IBD treatment.

Abstract
AIM According to the literature, high levels of salivary soluble E-cadherin may be lined to advanced stage and poor prognosis in cancers. This research aimed at comparing salivary and serum levels of soluble E-cadherin in cases with esophageal, gastric, and colorectal cancers. METHODS This case-control research was performed on 68 patients with gastrointestinal cancers and 57 healthy volunteers as a control group to measure salivary and serum levels of soluble E-cadherin using ELISA kits. RESULTS The results showed a statistically significant difference between salivary and serum levels of soluble E-cadherin in the case group, as opposed to the control group (P = 0.031). The salivary level of soluble E-cadherin in the control group was 2.138 ng/mL on average lower than that that in the case group. The median salivary level of soluble E-cadherin among cases with lymph node involvement was significantly higher compared with its median level in the control group (P = 0.049). Soluble E-cadherin salivary level and other variables, such as metastasis and cancer stage, were directly correlated, but it was not statistically significant. CONCLUSION According to the findings, the salivary level of soluble E-cadherin among cases with gastric cancer could be considered as a prognostic marker, but the diagnostic value of saliva could not be judged in esophageal and colorectal cancers because of small sample size, and more investigations are required for a definite conclusion.

Abstract
BACKGROUND Close to three-quarters of ovarian cancer cases are frequently diagnosed at an advanced stage, with more than 70% of them failing to respond to primary therapy and relapsing within 5 years. There is an urgent need to identify strategies for early detection of ovarian cancer recurrence, which may lead to earlier intervention and better outcomes. METHODS A customized magnetic bead-based 8-plex immunoassay was evaluated using a Bio-Plex 200 Suspension Array System. Target protein levels were analyzed in sera from 58 patients diagnosed with advanced ovarian cancer (including 34 primary and 24 recurrent tumors) and 46 healthy controls. The clinical performance of these biomarkers was evaluated individually and in combination for their ability to detect recurrent ovarian cancer. RESULTS An 8-plex immunoassay was evaluated with high analytical performance suitable for biomarker validation studies. Logistic regression modeling selected a two-marker panel of CA-125 and VCAM-1 that improved the performance of CA-125 alone in detecting recurrent ovarian cancer (AUC: 0.813 versus 0.700). At a fixed specificity of 83%, the two-marker panel significantly improved sensitivity in separating primary from recurrent tumors (70.8% versus 37.5%, P = 0.004), demonstrating that VCAM-1 was significantly complementary to CA-125 in detecting recurrent ovarian cancer. CONCLUSIONS A two-marker panel of CA-125 and VCAM-1 showed strong diagnostic performance and improvement over the use of CA-125 alone in detecting recurrent ovarian cancer. The experimental results warrant further clinical validation to determine their role in the early detection of recurrent ovarian cancer.

Abstract
Ultrasound imaging is a widely used, readily accessible and safe imaging modality. Molecularly-targeted microbubble- and nanobubble-based contrast agents used in conjunction with ultrasound imaging expand the utility of this modality by specifically targeting and detecting biomarkers associated with different pathologies including cancer. In this study, nanobubbles directed to a cancer biomarker derived from the Receptor Protein Tyrosine Phosphatase mu, PTPmu, were evaluated alongside non-targeted nanobubbles using contrast enhanced ultrasound both in vitro and in vivo in mice. In vitro resonant mass and clinical ultrasound measurements showed gas-core, lipid-shelled nanobubbles conjugated to either a PTPmu-directed peptide or a Scrambled control peptide were equivalent. Mice with heterotopic human tumors expressing the PTPmu-biomarker were injected with PTPmu-targeted or control nanobubbles and dynamic contrast-enhanced ultrasound was performed. Tumor enhancement was more rapid and greater with PTPmu-targeted nanobubbles compared to the non-targeted control nanobubbles. Peak tumor enhancement by the PTPmu-targeted nanobubbles occurred within five minutes of contrast injection and was more than 35% higher than the Scrambled nanobubble signal for the subsequent two minutes. At later time points, the signal in tumors remained higher with PTPmu-targeted nanobubbles demonstrating that PTPmu-targeted nanobubbles recognize tumors using molecular ultrasound imaging and may be useful for diagnostic and therapeutic purposes.

Soluble VCAM-1 promotes gemcitabine resistance via macrophage infiltration and predicts therapeutic response in pancreatic cancer. Sci Rep 2020; 10:21194.

Abstract
Pancreatic cancer is one of the malignant diseases with the worst prognosis. Resistance to chemotherapy is a major difficulty in treating the disease. We analyzed plasma samples from a genetically engineered mouse model of pancreatic cancer and found soluble vascular cell adhesion molecule-1 (sVCAM-1) increases in response to gemcitabine treatment. VCAM-1 was expressed and secreted by murine and human pancreatic cancer cells. Subcutaneous allograft tumors with overexpression or knock-down of VCAM-1, as well as VCAM-1-blocking treatment in the spontaneous mouse model of pancreatic cancer, revealed that sVCAM-1 promotes tumor growth and resistance to gemcitabine treatment in vivo but not in vitro. By analyzing allograft tumors and co-culture experiments, we found macrophages were attracted by sVCAM-1 to the tumor microenvironment and facilitated resistance to gemcitabine in tumor cells. In a clinical setting, we found that the change of sVCAM-1 in the plasma of patients with advanced pancreatic cancer was an independent prognostic factor for gemcitabine treatment. Collectively, gemcitabine treatment increases the release of sVCAM-1 from pancreatic cancer cells, which attracts macrophages into the tumor, thereby promoting the resistance to gemcitabine treatment. sVCAM-1 may be a potent clinical biomarker and a potential target for the therapy in pancreatic cancer.

Abstract
Helicobacter pylori (H. pylori) is well-known to be involved in gastric carcinogenesis, associated with deregulation of cell proliferation and epigenetic changes in cancer-related genes. H. pylori infection is largely acquired during childhood, persisting long-term in about half of infected individuals, a subset of whom will go on to develop peptic ulcer disease and eventually gastric cancer, however, the sequence of events leading to disease is not completely understood. Knowledge on carcinogenesis and gastric damage-related biomarkers is abundant in adult populations, but scarce in children. We performed an extensive literature review focusing on gastric cancer related biomarkers identified in adult populations, which have been detected in children infected with H. pylori. Biomarkers were related to expression levels (RNA or protein) and/or methylation levels (DNA) in gastric tissue or blood of infected children as compared to non-infected controls. In this review, we identified 37 biomarkers of which 24 are over expressed, three are under expressed, and ten genes are significantly hypermethylated in H. pylori-infected children compared to healthy controls in at least 1 study. Only four of these biomarkers (pepsinogen I, pepsinogen II, gastrin, and SLC5A8) have been studied in asymptomatically infected children. Importantly, 13 of these biomarkers (β-catenin, C-MYC, GATA-4, DAPK1, CXCL13, DC-SIGN, TIMP3, EGFR, GRIN2B, PIM2, SLC5A8, CDH1, and VCAM-1.) are consistently deregulated in infected children and in adults with gastric cancer. Future studies should be designed to determine the clinical significance of these changes in infection-associated biomarkers in children and their persistence over time. The effect of eradication therapy over these biomarkers in children if proven significant, could lead to modifications in treatment guidelines for younger populations, and eventually promote the development of preventive strategies, such as vaccination, in the near future.

Abstract
Cancer-associated fibroblasts (CAFs) play a major role in the progression of stomach cancer, but the related mechanisms are not fully understood. H. pylori infection is recognized as one of the strongest risk factors for gastric carcinoma, but its effects on CAFs remain unknown. We aimed to determine the causative relationship between H. pylori infection in fibroblasts and the promoted cancer pathogenesis and progression in gastric cancer. Primary CAFs and normal activated fibroblasts (NAFs) were generated from gastric cancer patients. Gene signature of H. pylori-infected human stomach fibroblasts was performed using the RNA-seq analysis. Spheroid cell invasion assay and zebrafish cell line-derived xenograft (zCDX) model were introduced to evaluate tumor invasion induced by CAFs. The molecule interactions were determined using the kinetic binding analysis with the Biolayer Interferometry (BLI). Clinical significance and relevance were also assessed using the database analyses. H. pylori infection activated stomach fibroblasts and caused multiple gene alterations, including vascular adhesion molecule 1 (VCAM1). H. pylori infection increased VCAM1 expression in CAFs in gastric carcinoma via activation of JAK/STAT1 signaling pathway, and VCAM1 levels were positively associated with tumor progression and dismal prognosis in stomach cancer patients. Furthermore, CAFs-derived VCAM1 molecularly interacted with integrin αvβ1/5 in gastric cancer cells facilitated tumor invasion in vitro and in vivo. Our results identify a novel mechanism underlying CAFs to promote tumor invasion during H. pylori infection. These studies facilitate us for a better understanding of the molecular process of gastric carcinoma progression, and provide the potential strategies for gastric cancer therapy.

Abstract
BACKGROUND Gastric cancer is still the main health threat being the third leading cause of deaths from cancers in the world. The major risk behind the gastric cancer is that it remains asymptomatic in the early stages and in (97%) cases it metastasizes to other organs. Gastric cancer is a multifactorial disease in which Helicobacter pylori (H. pylori) has been known as a risk factor. However, patients with gastritis, especially atrophic gastritis and gastric ulcer have been shown to be at an increased risk for developing gastric cancer. METHODS This study included measuring the serum levels of E-Cadherin protein, carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA) in 30 patients diagnosed with gastritis, 20 gastric ulcer patients, 20 gastric cancer patients and in 20 healthy volunteers serving as the control group. RESULTS Infection with H. pylori was diagnosed by serology (IgA and IgG antibodies) as well as by rapid urease test (RUT) and histology. The results showed that 50 (71.4%) of the patients were positive for H. pylori. Levels of E-Cadherin were increased significantly in all patients in comparison to the control group with a large significant increase in the gastric cancer group. The levels of E-Cadherin were also significantly increased in H. pylori infected patients compared to H. pylori negative patients. A non-significant difference in the levels of CA19-9 and CEA was observed in all patients in comparison to healthy controls. CONCLUSION This study concluded that serum E-Cadherin could be considered as a potential marker in diagnosis of gastric cancer.

Abstract
Background Angiogenesis is a prerequisite for tumor growth and metastasis. Vascular cell adhesion molecule-1 (VCAM-1) is expressed on endothelial cells as a result of vascular endothelial growth factor (VEGF) stimulation. Purpose To determine if measurement in serum of VEGF or VCAM-1 provides an accurate measure of tumor angiogenesis. Methods VCAM-1 and VEGF were measured in the serum of women with early and advanced breast cancer by ELISA. Levels were compared to levels of VCAM-1 and VEGF in women with normal breasts and levels of the endothelial glycoprotein von Willebrand factor. Levels of VEGF and VCAM-1 in women with early breast cancer were correlated with established clinicopathological prognostic markers and intratumoral microvessel density (IMD). Results In early breast cancer serum VCAM-1 correlated closely with the microvessel density in tumors (r=0.61, p<0.001). Women with lymph node-positive and high-grade tumors had higher levels of serum VCAM-1 than women with lymph node-negative and low-grade tumors. Serum VEGF demonstrated no correlation with established prognostic features or IMD. Levels of VCAM-1 and VEGF were raised in women with advanced breast cancer. Conclusion Serum VCAM-1 is a surrogate marker of angiogenesis in breast cancer and its measurement may help in the assessment of antiangiogenic drugs currently in phase II trials.

Abstract
BACKGROUND Mesothelium vascular cell adhesion molecule-1 (VCAM-1) expression in the metastatic epithelial ovarian cancer (EOC) microenvironment is induced by tumor and mediates tumor cell invasion. VCAM-1 imaging suggests expression during treatment is an indicator of platinum resistance. Here, we assess the potential prognostic significance of mesothelium VCAM-1 expression and prospectively evaluate whether soluble VCAM-1 (sVCAM-1) is a surrogate for mesothelium expression. METHODS A retrospective review of EOC patients was performed to evaluate outcomes with mesothelium VCAM-1 expression determined by immunohistochemistry of peritoneum or omentum specimens. A prospective cohort of EOC patients was identified and followed through primary treatment. Serum for sVCAM-1 evaluation, which was performed via enzyme-linked immunosorbent assay, was collected before surgery or neoadjuvant chemotherapy and at each treatment cycle. Peritoneal specimens were obtained during debulking to assess mesothelial VCAM-1 expression. RESULTS A retrospective review identified 54 advanced-stage EOC patients. Patients expressing mesothelium VCAM-1 had shortened overall survival (44 vs 79 months, P = 0.035) and progression-free survival (18 vs 67 months, P = 0.010); the median time to platinum resistance was 36 months for VCAM-1-expressing patients and not yet determined for the VCAM-1-negative group. In our prospective observational cohort, 18 EOC patients completed primary treatment; 3 were negative for mesothelium VCAM-1 expression, and sVCAM-1 did not vary between groups. CONCLUSIONS Mesothelium VCAM-1 expression is negatively associated with progression-free and overall survival in EOC. This is especially compelling in light of previous data suggesting that persistent VCAM-1 expression during treatment is an indicator of platinum resistance. Our pilot study had insufficient cases to determine whether sVCAM-1 would substitute for mesothelium expression. Cancer 2017;123:977-84. © 2016 American Cancer Society.

Abstract
OBJECTIVE Breast carcinoma is the most common malignant tumor detected in women. The hypothesis that increased levels of adhesion molecules and Cathepsin D affect cancerous cells moving away the primary tumor and contributes to migration of the cancerous cell and may cause remote organ metastases is defended. The aim of the present study was to search the association of intracellular adhesion molecule-1 (ICAM-1), vascular adhesion molecule-1 (VCAM-1), Cyclin D1, cathepsin D immunohistochemically with clinicopathological parameters in the patients diagnosed with invasive ductal breast carcinoma. MATERIALS AND METHODS The pathological slides of 153 patients diagnosed with invasive ductal carcinoma were evaluated retrospectively. Three groups were created. Group 1 consisted of patients with positive lymph node metastasis and extranodal tumor invasion; Group 2 consisted of patients with positive axillary lymph node metastasis and negative extranodal tumor invasion and Group 3 consisted of the patients with negative axillary lymph node metastasis. In all groups, 20 paraffin blocks belonging to the primary tumor in the breast were stained by ICAM-1, VCAM-1, Cyclin D1 and Cathepsin D. Findings were examined by comparing with clinicopathological parameters. RESULTS The highest number of metastatic axillary lymph nodes and the highest rate of cathepsin D staining were statistically found in the cases with positive axillary lymph node metastasis and extranodal tumor invasion. CerbB2 was negative in the cases with negative ICAM-1 whereas estrogen receptor and progesterone receptor were positive in the cases with positive VCAM-1. CONCLUSION The present study reveals significant results for the patients diagnosed with invasive ductal carcinoma through breast biopsy especially before mastectomy in terms of increased number of metastatic axillary lymph nodes and extranodal tumor invasion by immunohistochemical Cathepsin D stain without any additional invasive intervention. Results of the present study may contribute to monitoring and treatment of the patients in the future.

E-cadherin and gastric cancer: cause, consequence, and applications. BIOMED RESEARCH INTERNATIONAL 2014; 2014:637308.

Abstract
E-cadherin (epithelial-cadherin), encoded by the CDH1 gene, is a transmembrane glycoprotein playing a crucial role in maintaining cell-cell adhesion. E-cadherin has been reported to be a tumor suppressor and to be down regulated in gastric cancer. Besides genetic mutations in CDH1 gene to induce hereditary diffuse gastric cancer (HDGC), epigenetic factors such as DNA hypermethylation also contribute to the reduction of E-cadherin in gastric carcinogenesis. In addition, expression of E-cadherin could be mediated by infectious agents such as H. pylori (Helicobacter pylori). As E-cadherin is vitally involved in signaling pathways modulating cell proliferation, survival, invasion, and migration, dysregulation of E-cadherin leads to dysfunction of gastric epithelial cells and contributes to gastric cancer development. Moreover, changes in its expression could reflect pathological conditions of gastric mucosa, making its role in gastric cancer complicated. In this review, we summarize the functions of E-cadherin and the signaling pathways it regulates. We aim to provide comprehensive perspectives in the molecular mechanism of E-cadherin and its involvement in gastric cancer initiation and progression. We also focus on its applications for early diagnosis, prognosis, and therapy in gastric cancer in order to open new avenues in this field.

Abstract
BACKGROUND Vascular adhesion protein-1 (VAP-1) is a glycoprotein that mediates tissue-selective lymphocyte adhesion in a sialic acid-dependent manner. The prognostic importance of VAP-1 was determined in various human cancers. The aim of this study was to determine the relationship between VAP-1 and prognosis of gastric cancer. MATERIALS AND METHODS Serum of operable and metastatic gastric cancer patients was collected before treatment (surgery, radiotherapy, and/or chemotherapy). VAP-1 levels were measured by enzyme-linked immunosorbent assay. RESULTS A total of 86 gastric cancer patients (32 female, 54 male) were included in the study. Curative surgical treatment was performed in 54 (62.8%) patients. The mean serum VAP-1 level was 324.4 pg/ml and significantly higher in operable gastric cancer patients compared to metastatic gastric cancer patients (383.1 ± 173.5 vs. 225.2 ± 113.9 pg/ml; p < 0.001). When a cut-off value for VAP-1 of 218.8 pg/ml was determined by receiver operating characteristic (ROC) curves for presence of metastasis, sensitivity and specificity were 81.5 and 65.6%, respectively. Patients with decreased VAP-1 levels had a significantly poorer prognosis compared to patients with increased serum VAP-1 levels (median survival 8.2 vs. 23.5 months; p < 0.001). Multivariate analysis showed that VAP-1 is an independent prognostic factor of gastric cancer (odds ratio 2.3, 95% confidence interval 1.1-4.9; p = 0.032). CONCLUSION A low serum VAP-1 level may be an indicator of poor prognosis in gastric cancer. This study demonstrated that low serum VAP-1 levels are associated with poor prognosis in gastric cancer patients.

Abstract
Vascular cell adhesion molecule-1 (VCAM-1) first attracted attention more than two decades ago as endothelial adhesion receptor with key function for leukocyte recruitment in term of cellular immune response. The early finding of VCAM-1 binding to melanoma cells, and thus a suggested mechanistic contribution to metastatic spread, was the first and for a long time the only link of VCAM-1 to cancer sciences. In the last few years, hallmarked by a growing insight into the molecular understanding of tumorigenicity and metastasis, an impressive variety of VCAM-1 functionalities in cancer have been elucidated. The present review aims to provide a current overview of VCAM-1 relevance for tumor growth, metastasis, angiogenesis, and related processes. By illustrating the intriguing role of VCAM-1 in cancer disease, VCAM-1 is suggested as a new and up to now underestimated target in cancer treatment and in clinical diagnosis of malignancies.

Abstract
BACKGROUND AND PURPOSE Paeoniflorin (PF) has ameliorative effects on learning and memory impairment and cerebral ischaemia in rats and has protective effects against the degeneration of dopaminergic neurons in substantia nigra. The neuroprotective effects of PF are most probably derived from its anti-inflammatory property. Abnormally high levels of intercellular adhesion molecule-1 (ICAM-1) have been found to be associated with a wide range of inflammatory and immune responses. Here we studied whether PF regulates the levels of ICAM-1 elevated in LPS-activated differentiated human monocytic U937 cells and TNF-α-stimulated human umbilical vein endothelial cells (HUVECs). EXPERIMENTAL APPROACH mRNA levels were evaluated by RT-PCR. Protein levels were evaluated by Western blot analysis. An immunofluorescence technique was used to estimate NF-κB translocation, and NF-κB binding to nuclear DNA was determined by EMSA. KEY RESULTS PF inhibited ICAM-1 expression elevated in LPS-induced U937 cells and TNF-α-stimulated HUVECs. Although previous reports showed that PF's action is mediated by activating adenosine A₁ receptors, application of a selective adenosine A₁ receptor antagonist did not change the inhibitory effect of PF in our experiments. To elucidate the underlying mechanisms of the effect of PF, we studied its effect on signalling pathways upstream of ICAM-1 expression. PF suppressed the activation of the NF-κB pathway, which regulates the expression of ICAM-1. The TLR4 and MAPK pathways were shown not to be involved in the effects of PF in these cells. CONCLUSIONS AND IMPLICATIONS PF inhibits ICAM-1 expression in LPS-treated U937 cells and TNF-α-stimulated HUVECs by suppressing the activation of the NF-κB pathway.

Abstract
Host immune responses are critical steps for carcinogenesis. Single nucleotide polymorphisms (SNPs) in immunoregulatory genes may influence gastric cancer risk. We performed a genotyping analysis for immunoregulatory genes in 311 gastric cancer cases and 425 controls from a Chinese population. We found that there were significant differences of E-selectin variant rs5361 (A>C) and FCGR2A variant rs1801274 (T>C) between cases and controls (P = 0.022 and P = 0.0001, respectively). Logistic regression analysis indicated that genotype of E-selectin rs5361AC increased the risk of gastric cancer significantly (P = 0.026, adjusted Odds ratio (OR) = 2.84, 95% confidence interval (CI) = 1.13-7.12). C allele of E-selectin rs5361 showed a significant increased frequency in cases (P = 0.023). However, the E-selectin variant did not affect the protein expression. E-selectin protein was observed not only in tumor interstitial vascular endothelial cells, but also in gastric cancer cells at primary and metastatic sites. The protein was associated with clinicopathological characteristics of gastric cancer, such as age (P = 0.008), tumor size (P = 0.027), differentiation (P = 0.000), and tumor-node-metastasis (TNM) stage (P = 0.006). CT and CC + CT genotypes of FCGR2A variant rs1801274 increased gastric cancer risk (P = 0.000, adjusted OR = 1.92, 95%CI = 1.36-2.72; P = 0.003, adjusted OR = 1.68, 95%CI = 1.20-2.35, respectively). Interleukin-4 receptor (IL-4R) variant rs2107356 presented negative correlations to E-selectin variant rs5361 and FCGR2A variant rs1801274 (P = 0.035 and P = 0.023) in conferring susceptibility to gastric cancer. We concluded E-selectin variant rs5361 and FCGR2A variant rs1801274 were significantly associated with gastric cancer risk. Expression of E-selectin protein would promote progression of gastric cancer.

Abstract
Immunodepletion of clinical fluids to overcome the dominance by a few very abundant proteins has been explored but studies are few, commonly examining only limited aspects with one analytical platform. We have systematically compared immunodepletion of 6, 14, or 20 proteins using serum from renal transplant patients, analysing reproducibility, depth of coverage, efficiency, and specificity using 2-D DIGE (‘top-down’) and LC-MS/MS (‘bottom-up’). A progressive increase in protein number (≥2 unique peptides) was found from 159 in unfractionated serum to 301 following 20 protein depletion using a relatively high-throughput 1-D-LC-MS/MS approach, including known biomarkers and moderate–lower abundance proteins such as NGAL and cytokine/growth factor receptors. On the contrary, readout by 2-D DIGE demonstrated good reproducibility of immunodepletion, but additional proteins seen tended to be isoforms of existing proteins. Depletion of 14 or 20 proteins followed by LC-MS/MS showed excellent reproducibility of proteins detected and a significant overlap between columns. Using label-free analysis, greater run-to-run variability was seen with the Prot20 column compared with the MARS14 column (median %CVs of 30.9 versus 18.2%, respectively) and a corresponding wider precision profile for the Prot20. These results illustrate the potential of immunodepletion followed by 1-D nano-LC-LTQ Orbitrap Velos analysis in a moderate through-put biomarker discovery process.

Abstract
Under persistent antigenic stimulation, virus-specific CD8⁺ T cells become increasingly dysfunctional and up-regulate several inhibitory molecules such as killer lectin-like receptor G1 (KLRG1). Here, we demonstrate that HIV-1 antigen-specific T cells from subjects with chronic-progressive HIV-1 infection have significantly elevated KLRG1 expression (P < .001); show abnormal distribution of E-cadherin, the natural ligand of KLRG1, in the intestinal mucosa; and have elevated levels of systemic soluble E-cadherin (sE-cadherin) that significantly correlate with HIV-1 viral load (R = 0.7, P = .004). We furthermore demonstrate that in the presence of sE-cadherin, KLRG1(hi) HIV-1-specific CD8⁺ T cells are impaired in their ability to respond by cytokine secretion on antigenic stimulation (P = .002) and to inhibit viral replication (P = .03) in vitro. Thus, these data suggest a critical mechanism by which the disruption of the intestinal epithelium associated with HIV-1 leads to increased systemic levels of sE-cadherin, which inhibits the effector functions of KLRG1(hi)-expressing HIV-1-specific CD8⁺ T cells systemically.

Abstract
The aim of this study was to analyse whether some cases of unexplained infertility and implantation failure after IVF could be explained by different expression levels of the matrix metalloproteinases (MMP-2, 9), their tissue inhibitors (TIMP-2, 3) and intercellular (ICAM-1) and vascular (VCAM-1) adhesion molecules in endothelial cells. Total RNA was extracted from the endometrial tissues of 41 women (unexplained infertile, group 1, n = 15; fertile volunteers, group 2, n = 15 and patients with implantation failure after IVF, group 3, n = 11). MMP-2, MMP-9, TIMP-2, TIMP-3, ICAM-1 and VCAM-1 mRNA expression levels were measured quantitatively using real-time polymerase chain reaction. In the endometrium from women with unexplained infertility and implantation failure after IVF, MMP-2 and TIMP-3 expression were significantly decreased when compared with the fertile group (P < 0.05 and P </= 0.001 respectively). In addition, a marked decrease was observed in the expression of VCAM-1 in women with unexplained infertility. These results suggest that the expression of gelatinase A (MMP-2), TIMP-3 and VCAM-1, at least at the transcriptional level, might be regulated by common factors and signalling pathways. The present study adds new and important data in this field and highlights the complex preparation of the endometrium for implantation at the molecular level.

Abstract
Galectin-9, a member of galectin family, plays multiple roles in a variety of cellular functions, including cell adhesion, aggregation, and apoptosis. Galectin-9 also has three isoforms (named galectin-9L, galectin-9M, and galectin-9S), but whether these isoforms differ in their functions remains poorly understood. In this study, we showed that transient expression of galectin-9L decreased E-selectin levels, while transient expression of galectin-9M or galectin-9S increased E-selectin levels in LoVo cells, which do not express endogenous galectin-9. We also found that over-expression of three galectin-9 isoforms led to increased attachment of LoVo cells to extracellular matrix proteins respectively, while over-expression of galectin-9M or galectin-9S increased the adhesion of LoVo cells to human umbilical vein endothelial cells in vitro. In summary, these findings indicate that different isoforms of galectin-9 exhibit distinct biological functions.

Abstract
Molecular activities, regulating a balanced tissue organisation, are frequently disturbed during cancer progression. These include protein ectodomain shedding, a post-translational process that substantially changes the functional properties of the substrate protein. In comparison with normal epithelia, cancer cells almost invariably show diminished cadherin-mediated intercellular adhesion. This review will address cadherin ectodomain shedding and its functional consequence in normal physiology and in the tumor environment. Soluble cadherin fragments may retain specific biological activities during cancer cell invasion, angiogenesis and perineural invasion. When diffusion barriers disappear, soluble cadherins are detected in sera from cancer patients. Soluble N-(neural) cadherin may represent a novel diagnosis/prognostic biomarker showing a correlation with PSA in sera of prostate cancer patients. Furthermore, therapeutic monitoring in pancreas adenomacarcinoma revealed a correlation between circulating soluble N-cadherin and CA 19-9. A better understanding of cadherin regulation in cancer progression will likely increase our awareness of the importance of the combinatorial signals that regulate tissue integrity and eventually result in the identification of new therapeutics targeting cadherins.

Abstract
Bilirubin, the principal bile pigment, is the end product of heme catabolism. For many years, bilirubin was thought to have no physiological function other than that of a waste product of heme catabolism--useless at best and toxic at worst. Although hyperbilirubinemia in neonates has been shown to be neurotoxic, studies performed during the past decade have found that bilirubin has a number of new and interesting biochemical and biological properties. In addition, there is now a strong body of evidence suggesting that bilirubin may have a beneficial role in preventing oxidative changes in a number of diseases including atherosclerosis and cancer, as well as a number of inflammatory, autoimmune, and degenerative diseases. The results also suggest that activation of the heme oxygenase and heme catabolic pathway may have beneficiary effects on disease prevention either through the action of bilirubin or in conjunction with bilirubin. If so, it may be possible to therapeutically induce heme oxygenase, increase bilirubin concentrations, and lower the risk of oxidative stress-related diseases.

Abstract
PURPOSE Vascular cell adhesion molecule 1 (VCAM1) is a cell surface glycoprotein implicated in various pathophysiologic conditions. We measured VCAM1 expression levels in tumor tissues and evaluated its significance and prognostic use in renal cell carcinoma (RCC). EXPERIMENTAL DESIGN We used real-time quantitative PCR to examine the VCAM1 expression levels of a total of 485 sporadic renal tumors, including 429 clear cell, 21 papillary, 17 chromophobe, 11 oncocytomas, and 7 collecting duct carcinomas. We retrospectively examined the relationship of this expression to various clinicopathologic variables and the von Hippel-Lindau alteration status. We evaluated its significance with respect to patient survival rates using the Cox regression model combined with the split-sample method. RESULTS Compared with normal kidney samples (n = 43), VCAM1 was significantly up-regulated in clear cell RCC and papillary RCC, whereas it was down-regulated in chromophobe RCC and oncocytoma. In clear cell RCC, VCAM1 expression levels were apparently high in patients asymptomatic at presentation and in patients with small tumor size, low-stage, low-grade, microvascular invasion-negative, and von Hippel-Lindau alteration-positive tumors. Univariate analyses showed that VCAM1 high expression is strongly associated with better outcomes in clear cell and papillary RCCs. Further, Cox multivariate analysis models combined with the split-sample method revealed that this association is significant only in cancer-free survival for patients with clear cell RCC after curative surgical resection. CONCLUSIONS VCAM1 expression levels were found to be histologically subtype specific in renal tumors. Determination of the VCAM1 expression level as a biomarker can provide useful prognostic information for patients with clear cell RCC.

[PMID: 16934424 DOI: 10.1016/j.anl.2006.05.008] [Citation(s) in RCA: 17] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2006] [Revised: 04/25/2006] [Accepted: 05/26/2006] [Indexed: 11/22/2022]
Abstract
OBJECTIVE Lung and synovial fibroblasts produce VCAM-1 in response to TNF-alpha. However, the massive infiltration of eosinophils, the effects of the increased amount of TNF-alpha and the production of VCAM-1 in human nasal polyp fibroblasts are not yet fully understood. The present study examines the role of VCAM-1 and the molecular mechanism of its expression in nasal fibroblasts. METHODS Nasal fibroblasts were isolated from human nasal polyps and after four passages, the cells were stimulated with TNF-alpha and VCAM-1 expression was examined by ELISA, flow cytometry, and RT-PCR. The activation of NF-kappaB induced by TNF-alpha was determined by electrophoretic mobility shift assays and the influence on the expression of VCAM-1 was investigated. RESULTS VCAM-1 protein and mRNA were expressed in unstimulated controls and remarkably increased by TNF-alpha stimulation. NF-kappaB activity was enhanced by TNF-alpha stimulation and remarkably suppressed by NF-kappaB proteasome inhibitor. CONCLUSIONS The present study discovered that nasal fibroblasts produce VCAM-1 protein and mRNA and that production is increased by TNF-alpha stimulation. Furthermore, VCAM-1 expression in nasal fibroblasts is induced through an NF-kappaB-dependent pathway. These findings might provide a rationale for using NF-kappaB inhibitors as a treatment for nasal inflammatory diseases such as polyps.

Abstract
BACKGROUND/AIMS Cell adhesion molecules play a critical role in the invasion and metastasis of a variety of human tumors. Abnormal expression of VCAM-1 has been demonstrated to correlate with the malignant progression of gastric tumors, but the molecular mechanism underlying the VCAM-1-dependent metastasis has been rarely investigated. To explore the role for tumor cell-expressing adhesion molecules in the carcinoma-endothelium adhesion, we analyzed expression status of adhesion molecules in gastric cancer cells and its association with tumor cell capability of endothelial adhesion. METHODS Endothelial adhesion ability of gastric tumor cells was tested using calcein AM staining assay. Expression of cell surface proteins was determined by Western blot, flow cytometry, and immunofluorescence assays. RNAi-mediated knockdown of gene expression and neutralization with specific antibodies were utilized for functional analysis. RESULTS One of three cell lines tested was identified to be adhesive to endothelial cells and express VCAM-1. Adherence ability of the cells was dramatically decreased by neutralization of surface VCAM-1. VCAM-1 was co-localized with Caveolin-1 and siRNA-mediated knockdown of Caveolin-1 expression significantly blocked the VCAM-1-dependent cell adhesion. CONCLUSIONS Our data imply important roles for VCAM-1 and Caveolin- 1 in the regulation of metastatic potential of gastric tumor cells.

Abstract
Osteoblasts constitute part of the stromal cell support system in marrow for hematopoiesis, however little is known as to how they interact with hematopoietic stem cells (HSCs). In vitro studies have demonstrated that the survival of HSCs in co-culture with osteoblasts requires intimate cell-to-cell contact. This suggests that the osteoblast-derived factor(s) that supports stem cell activities are produced in very small quantities, are rapidly turned over, may be membrane-anchored and/or require the engagement of cell-cell adhesion molecules that are yet to be determined. In the present report we found that the survival of hematopoietic progenitor cells on osteoblasts is dependent upon the engagement of VLA-4 (alpha4beta1) and VLA-5 (alpha5beta1) receptors using function blocking antibodies. Cell-to-cell contact is required to support progenitor activity, but can be replaced if receptor-ligand engagement of the VLA-4 and LFA-1 complexes is provided through the use of recombinant ligands (fibronectin, ICAM-1, VCAM-1). Moreover, once these receptors were engaged, conditioned medium derived from HSCs grown on osteoblast ligands supported significantly greater hematopoietic progenitors in vitro than did osteoblast-conditioned or HSC-conditioned medium alone. While the molecules present in the co-cultured medium remain to be identified, the data suggest that hematopoietic cells cooperate with osteoblasts to assemble the various marrow microenvironments by directing the synthesis of osteoblast-derived cytokines to improve HSC survival.

Abstract
BACKGROUND The expression of adhesion molecules is important for the interaction of myeloma cells with the bone marrow microenvironment. In the current study, serum soluble adhesion molecules (sICAM-1 and sE-selectin) were measured in untreated multiple myeloma (MM) patients in relation with other markers of disease activity. MATERIALS AND METHODS The study group consisted of 67 patients with MM (classified according to the Durie-Salmon classification) and 15 controls. Interleukin-6 (IL-6), sICAM-1 and sE-selectin concentrations were determined by enzyme-linked immunosorbent assay (ELISA). In addition, the monoclonal protein, erythrocyte sedimentation rate (ESR) and hemoglobin (Hb) concentration were also determined. RESULTS Serum sICAM-1 level increased significantly at advanced stages of MM and was higher in comparison to controls (p<0.01). sE-selectin increased significantly with advancing stage of the disease, but did not differ from controls. IL-6, ESR and M-component were significantly higher and Hb concentrations lower with advancing stage of disease. There was a positive correlation of IL-6 with sICAM-1 and sE-selectin. CONCLUSIONS We conclude that serum sICAM-1 differs in multiple myeloma patients from normals and together with sE-selectin increase in parallel to increasing stage of disease, which may reflect a dysregulation and possible involvement of these adhesion molecules in myeloma progression.

Abstract
This paper provides a bird’s-eye view both in preclinical and clinical aspects of E-cadherin germline gene (CDH1) in gastric cancer patients and their families. E-cadherin, a product of CDH1 gene, belonging to the functionally related trans-membrane glycoprotein family, is responsible for the Ca2+-dependent cell-cell adhesion mechanism and contributes to dissociation followed by acquisition of cell motility, which usually occurs in the first step of cancer invasion and metastasis. CDH1 gene germline mutation is common in many types of carcinoma, and occurs very frequent in hereditary gastric carcinoma (HGC) patients and their families. Recently, more and more researches support that E-cadherin plays an important role in the differentiation, growth and invasion of HGC. So it is of great value to clarify its mechanisms both for understanding HGC pathogenesis and for clinical therapy, especially in China, where there are a high risk population of gastric cancer and a high HGC incidence rate. In this paper, recent researches on CDH1 gene mutation, especially its role in tumor genesis and progress of HGC, are reviewed, and advances in evaluation of its mutation status for HGC diagnosis, therapy and prognosis, are also discussed briefly.

Abstract
In our present study we focused on soluble VCAM-1 (sVCAM-1)/alpha(4) integrin-induced angiogenesis and found that this type of angiogenesis was mediated through p38 mitogen-activated protein kinase and focal adhesion kinase (FAK). HUVEC expressed both alpha(4) and beta(1) integrins, and it was reported that expression of alpha(4) integrin and its counterreceptor, sVCAM-1/VCAM-1, was enhanced in response to an inflammatory cytokine, TNF-alpha. In endothelial cells phosphorylation of p38 and FAK, but not that of extracellular signal-regulated kinase 1/2 was induced by sVCAM-1. Migration of endothelial cells was stimulated in response to sVCAM-1 at similar levels as those induced by vascular endothelial growth factor, and sVCAM-1-induced migration was almost completely blocked by neutralizing Ab against alpha(4) integrin, by either an inhibitor of p38 (SB203580), or by adenovirus containing FAK-related nonkinase. sVCAM-1 also induced the formation of blood vessels in Matrigel plug assay in vivo, and this neovascularization was blocked by SB203580 or neutralizing Ab against alpha(4) integrin. Moreover, we also confirmed that both TNF-alpha and sVCAM-1 could synergistically induce angiogenesis in the corneas of mice when each factor at used dose could not induce. This angiogenesis by TNF-alpha and sVCAM-1 was almost completely blocked by coadministration of SB203580 and also by neutralizing Ab against alpha(4) integrin. These results suggest that sVCAM-1/alpha(4) integrin induces angiogenesis through p38 and FAK signaling pathways.

Abstract
OBJECTIVES This study evaluated serum concentrations of soluble cell adhesion molecules in patients with gastric cancer and in healthy control subjects. Our objectives were to correlate these levels with clinicopathological features, established tumor markers, and patient survival, and to assess changes in serum levels of cell adhesion molecules after tumor surgery. METHODS The serum concentrations of the adhesion molecules E-selectin, intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 (VCAM-1) were investigated by ELISA in 57 gastric cancer patients, both before and 7 days after surgery, and in 47 healthy control subjects. RESULTS Preoperative serum concentrations of ICAM-1 and VCAM-1 in gastric cancer patients were significantly higher when compared with those of healthy controls, whereas there were no differences regarding serum E-selectin levels. Serum levels of E-selectin, ICAM-1, and VCAM-1 correlated significantly with each other. There was a significant association between preoperative levels of all three adhesion molecules and disease stage, gastric wall invasion, lymph node involvement, and presence of distant metastases. Their concentrations decreased significantly after radical resection of the tumor, whereas they remained almost unchanged in patients with unresectable disease. Elevated preoperative serum levels of E-selectin, ICAM-1, and VCAM-1 levels were found in 24.6%, 33.3%, and 28.1% of patients, respectively. Elevated levels of all three molecules were significant prognostic factors for patient survival but not independent of disease stage. CONCLUSIONS These findings suggest that serum concentrations of E-selectin, ICAM-1, and VCAM-1 may reflect tumor progression and metastasis, and may be clinically useful.

Abstract
Ecalectin, produced by Ag-stimulated T lymphocytes, is a potent eosinophil-specific chemoattractant in vitro as well as in vivo and thus is implicated in allergic responses. Ecalectin differs structurally from other known eosinophil chemoattractants (ECAs); ecalectin belongs to the galectin family defined by their affinity for beta-galactosides and by their conserved carbohydrate recognition domains. These characteristic features suggest that ecalectin has unique activities associated with allergic inflammation besides ECA activity. Conversely, ecalectin may mediate ECA activity by binding to a receptor of a known ECA via affinity for the beta-galactosides present on this receptor. In this study, we have tested whether ecalectin mediates ECA activity by binding to a receptor of a known ECA, and we have assessed its effects on eosinophils. Ecalectin did not mediate ECA activity by binding to the IL-5R or to CCR3. Also, the ECA activity of ecalectin was mainly chemokinetic. In addition, ecalectin induced concentration-dependent eosinophil aggregation, a marker for eosinophil activation. Ecalectin induced concentration-dependent superoxide production from eosinophils but did not induce degranulation; usually these two events are coupled in eosinophil activation. Moreover, ecalectin directly prolonged eosinophil survival in vitro and did not trigger eosinophils to secrete cytokines that prolong eosinophil survival. These results demonstrate that ecalectin has several unique effects on eosinophils. Therefore, we conclude that ecalectin is a novel eosinophil-activating factor. Presumably, these effects allow ecalectin to play a distinctive role in allergic inflammation.

Abstract
The expression of the following cell adhesion molecules, their beta1 and beta2 integrin ligands and the cytokine tumour necrosis factor-alpha (TNF-alpha) was investigated by light and electron microscope immunohistochemistry in the liver tissue in 20 patients with colorectal and gastric cancer also presenting with liver metastases: intercellular adhesion molecule-1 (ICAM-1), vascular endothelial adhesion molecule-1 (VCAM-1), E-selectin, leucocyte function-associated antigen-1 (LFA-1), macrophage antigen-1 (Mac-1), and very late antigen-4 (VLA-4). We have found a parallel enhancement of the adhesion molecules and of TNF-alpha in liver sinusoids surrounding metastases. The expression of ICAM-1 was enhanced on sinusoidal cells in all zones of the acinus. VCAM-1 immune reactivity was diffuse but less intensive in the lobule. E-selectin expression was observed in sinusoidal cells attached to metastases. In tumour metastases the expression of ICAM-1, VCAM-1, and E-selectin was visible on the tumour vascular endothelium. Tumour infiltrating host cells sowing positive immunoreactivity for ICAM-1, VCAM-1, LFA-1, Mac-1, and VLA-4 were located mainly at the boundary between liver parenchyma and the metastasis. At the ultrastructural level, ICAM-1-positive immune deposits were observed on the cellular membrane and in some transport vesicles of gastric metastatic cells. Further, the expression of all adhesion molecules was confirmed to sinusoidal endothelial cells and tumour vessels. It is concluded that the enhanced expression of adhesion molecules in liver sinusoids could be a marker for the assessment of the ability of sinusoidal endothelial cells to control the recruitment of leukocytes and monocytes to the metastatic site. They could also direct the adhesion of new circulating tumour cells to sinusoidal endothelium.

Abstract
Prostate cancer, the leading male cancer in Western countries, has accelerated in its incidence in the past decade. Patients with prostate cancer frequently have a poor prognosis as a result of local or distant spread of cancer. This review summarises some of the recent progress made in understanding the biology of cancer metastasis with a special emphasis on the role of cell adhesion molecules and adhesion abnormalities. The molecular and cellular function of cell adhesion molecules, their role in cancer and cancer progression, the clinical impact of these molecules, and therapeutic considerations are also discussed.

Abstract
The germline coded human monoclonal IgM antibody 103/51 was isolated from a gastric carcinoma patient. This antibody binds to a 130-kd membrane molecule and has a mitotic effect on tumor cells in vitro. To characterize the target, we sequenced the protein and showed that the antibody binds to the cysteine-rich fibroblast growth factor receptor (CFR)-1, which is highly homologous to MG-160 and the E-selectin-ligand (ESL)-1. The epitope was determined by glycosidase-digestion experiments to be an N-linked carbohydrate side chain. Immunohistochemistry was used to investigate the tissue distribution of CFR-1. Different healthy tissues were tested and only the collecting tubes of the kidney, the Golgi apparatus, and the glomerular and fascicular zones of the adrenal gland stained positive. However, on malignant tissue the receptor is overexpressed in nearly all tested stomach cancers (12 of 15) and other tested carcinomas (13 of 15). Most interestingly, the receptor is also present in Helicobacter pylori gastritis and gastric dysplasia, but absent on uninflamed stomach mucosa. This restricted tissue pattern indicates that antibody 103/51 reacts with a membrane-bound variant of CFR-1, which is mainly expressed on transformed cells and precursor lesions and is essential for proliferation processes. The possible activity of antibody 103/51 as an activating ligand in these proliferative changes of gastric epithelial mucosa is discussed.

Abstract
BACKGROUND Gastric cancer remains a major cause of cancer mortality globally but no good prognostic tumour marker is available. Soluble fragment of E-cadherin protein has been reported to increase in the sera of patients with cancer and recently was found to be elevated in 67% of patients with gastric cancer. AIMS To investigate if serum soluble E-cadherin is a valid prognostic marker in gastric cancer. METHODS Concentrations of soluble E-cadherin from 116 patients with histologically confirmed gastric adenocarcinoma and 40 healthy subjects were measured using an immunoenzymometric method with a commercially available sandwich ELISA kit based on monoclonal antibodies. RESULTS The logarithm of the means of soluble E-cadherin concentration was significantly higher in patients with gastric cancers (mean 3.85 (SD 0.28)) than in healthy subjects (3.71 (0.18)) (p=0.001), and in palliative/conservatively treated cancers (3.91 (0.35)) than in operable cancers (3.78 (0.19)) (p=0.015). The logarithm of the concentrations correlated with tumour size (p=0.032) and carcinoembryonic antigen concentrations (p=0.001). The cut off value calculated from discriminant analysis on operability and inoperability/palliative treatment was 7025 ng/ml. Soluble E-cadherin concentrations higher than this cut off value predicted tumour (T4) depth invasion (p=0.020, confidence interval (CI) 1.008-1.668) and palliative/conservative treatment (p=0.023, CI 1.038-2.514). In contrast, the relative risks for lymph node (N2) metastasis, distant metastasis, and stage III/IV disease were 1.41, 1.33, and 1.55 respectively, despite not reaching statistical significance. CONCLUSION Serum soluble E-cadherin is a potential valid prognostic marker for gastric cancer. A high concentration predicts palliative/conservative treatment and T4 invasion.

Abstract
BACKGROUND Angiogenesis, the development of new blood vessels from pre-existing vasculature, is a prerequisite for tumor growth and metastasis. Surrogate markers for angiogenesis would be useful for studying the effectiveness of antiangiogenesis drugs. We examined the potential of three serum glycoproteins-vascular cell adhesion molecule-1 (VCAM-1), endothelial selectin (E-selectin), and von Willebrand factor (VWF)-to serve as markers for angiogenesis. METHODS Preoperative serum levels of VCAM-1, E-selectin, and VWF were measured by enzyme-linked immunosorbent assay in 93 women with early breast cancer and were compared with microvessel density in each tumor, histologic features, and recurrence after surgery. Serum samples were taken from 55 women with advanced breast cancer who were commencing hormonal therapy, both immediately before therapy and 3 months later. Changes in serum levels of VCAM-1, E-selectin, and VWF were compared with the response of the disease to hormonal therapy assessed 6 months after the start of hormone therapy or at disease progression. All P: values are two-sided. RESULTS In women with early breast cancer, serum levels of VCAM-1 (but not of E-selectin or VWF) correlated closely with microvessel density in tumors (r =.65; P:<.001), and women who developed early recurrence had higher preoperative levels of serum VCAM-1 than those who remained disease free (P: =.01). Serum VCAM-1 levels rose in women with advanced breast cancer whose disease progressed (P:<.001) but remained unchanged or fell in women with advanced breast cancer whose disease remained stable or showed a partial response to hormonal therapy. CONCLUSION Serum VCAM-1 appears to be a surrogate marker of angiogenesis in breast cancer. Its measurement may, therefore, help in the assessment of antiangiogenesis drugs currently in phase II trials.

Abstract
Eosinophils are usually associated with parasitic and allergic diseases; however, eosinophilia is also observed in several types of human tumors, including breast carcinomas. In this study we examined several human breast carcinoma cell lines for adhesion molecule expression and the ability to bind and activate eosinophils. MDA-MB-435S and MDA-MB-468 cells constitutively expressed both intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) and this expression was enhanced by treatment with tumor necrosis factor-alpha (TNF-alpha). BT-20 and SK-BR-3 cells only expressed ICAM-1 or VCAM-1 after stimulation with TNF-alpha. Eosinophils constitutively bound to MDA-MB-435S cells, but not to BT-20 cells. Stimulation with TNF-alpha slightly enhanced eosinophil adhesion to MDA-MB-435S cells and dramatically increased adhesion to BT-20 cells. Greater than 80% of eosinophil adhesion to these cell lines was blocked with an anti-alpha4-integrin monoclonal antibody. Both MDA-MB-435S and BT-20 cells also released eosinophil activator(s). Supernatants from TNF-alpha-treated, but not control-treated, cell lines increased eosinophil adhesion to fibronectin and increased eosinophil transmigration across fibronectin-coated transwell plates. Enzyme-linked immunosorbent assays showed that TNF-alpha-stimulated breast carcinoma cells released the chemokine regulated on activation, T cell expressed and secreted (RANTES). Addition of an anti-RANTES antibody to breast carcinoma cell supernatants partially blocked eosinophil activation suggesting that RANTES in these supernatants was participating in eosinophil activation. These data show that TNF-alpha-stimulated breast carcinoma cells express mediators that can both bind and activate eosinophils, suggesting a mechanism for eosinophil localization to breast carcinoma sites.

Abstract
This is the first report of the serum profile of a glycosylated recombinant form of human IL-6 (rhIL-6) administered subcutaneously (1-10 microg/kg/day) in a phase I/II trial as a thrombopoietic agent in patients with advanced cancer. The pharmacodynamic effects of IL-6 were also examined. Detailed pharmacokinetic measurements were made in four patients. Peak concentrations at 5-8 h and a median t0.5 of ca. 5 h were similar to those previously reported for non-glycosylated IL-6. However, higher peak concentrations and apparent differences in effective dose levels to those previously reported with the non-glycosylated form were seen. Indications of an apparent attenuation in circulating IL-6 concentrations with continuing injections were seen in eight of 10 patients examined but anti-IL-6 antibody generation was seen in only two patients. Soluble interleukin 6 receptor concentrations generally decreased. No major changes in T cell subsets were seen but expression of CD25 and CD54 by T lymphocytes significantly increased, accompanied by marked increases in soluble CD25 (sIL-2R) and CD54 (sICAM-1). No consistent change in B cells, monocytes or NK cells were seen. No evidence for induction of TNF-alpha was found. This study demonstrates similar biological effects of glycosylated rhIL-6 to those reported for the non-glycosylated form but illustrates several apparent differences which are discussed further.

Abstract
To date, no soluble markers can discriminate benign from malignant breast lesions; therefore, to assess the diagnostic potential of circulating intercellular adhesion molecule-1 (sICAM-1), serum concentrations of sICAM-1 were quantitated in 230 consecutive patients that underwent surgery for breast neoplasias, utilizing an enzyme-linked immunosorbent assay. Histological diagnosis revealed that 177 patients had breast cancer and 53 had a benign breast disease. In the cancer patient group, 90 subjects had pT1 tumors without (pT1N0M0, n = 46) or with (pT1N1M0, n = 41; pT1N2M0, n = 3) regional lymph node metastases. Mean levels of serum sICAM-1 of patients with pT1 breast cancer, without or with regional lymph node involvement, were significantly (P < 0.05) higher than those of patients with benign breast lesions and of 49 age-matched control subjects. Elevated levels of serum sICAM-1 were detected in 27/90 (30%) pT1 breast tumors and in 1/53 (2%) benign breast lesions; thus, among subjects with high levels of sICAM-1, 96% had breast cancer. No significant correlation was found between levels of serum sICAM-1 and breast cancer progression. These observations, altogether, suggest that in the presence of a suspicious breast neoplasm the quantitative analysis of serum sICAM-1 can orient clinical diagnosis towards malignancy.

Abstract
The selectins are a family of intercellular adhesion molecules that mediate the attachment of leukocytes to the endothelial lining of blood vessels. Another biological process that may involve selectins is the adhesion of circulating tumour cells to endothelium in cancer metastasis. This review discusses the evidence for the involvement of E-, P- and L-selectin in the metastasis of different tumour types. It is concluded that, with certain reservations and qualifications, selectins can play a role in metastasis. For example, the evidence for the involvement of E-selectin in breast and colon cancer metastasis is very strong. For the other selectins and tumour types the evidence is less convincing and further investigations are required to clarify the situation. Certainly, selectins are not the only mechanism available for tumours to metastasise. In the future, measurement of selectins could be useful prognostically and manipulation of their levels could lead to new cancer therapies.

Abstract
The concentrations of the soluble adhesion molecules E-cadherin, E-selectin, intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) were investigated in 48 patients with colorectal cancer before treatment, and their relation to clinical, histological and routine laboratory parameters was examined. Data were collected on tumour stage at presentation, presence and sites of metastatic disease, tumour pathology and results of routine laboratory tests. Serum concentrations of ICAM-1 and VCAM-1 were significantly elevated in the patients with colorectal cancer in comparison with a group of healthy subjects (P < 0.00001). Levels of circulating ICAM-1 and VCAM-1 were increased both in patients with local and those with metastatic disease. Although elevated in some patients soluble E-cadherin and E-selectin concentrations were not significantly elevated compared with the control group (P = 0.71 and P = 0.052 respectively). The levels of circulating ICAM-1 were significantly correlated with those of VCAM-1 and E-selectin. A correlation was also found between the serum concentrations of E-selectin and ICAM-1 and alkaline phosphatase, total white cell count and platelet count. VCAM-1 was positively correlated with age and negatively with degree of tumour differentiation and haemoglobin concentration. The biological implications and possible clinical relevance of these findings are discussed.
