Abstract
Hepatocellular carcinoma (HCC) is one of the most fatal solid malignancies worldwide. Evidence suggests that thrombin stimulates tumor progression via fibrin formation and platelet activation. Meanwhile, we also found a correlation between thrombin and HCC through bioinformatics analysis. Dabigatran is a selective, direct thrombin inhibitor that reversibly binds to thrombin. Dabigatran was used as the lead agent in this study, and 19 dabigatran derivatives were designed and synthesized based on docking mode. The thrombin-inhibitory activity of the derivative AX-2 was slightly better than that of dabigatran. BX-2, a prodrug of AX-2, showed a fairly strong inhibitory effect on thrombin-induced platelet aggregation, and effectively antagonized proliferation of HCC tumor cells induced by thrombin at the cellular level. Furthermore, BX-2 reduced tumor volume, weight, lung metastasis, and secondary tumor occurrence in nude mouse models. BX-2 combined with sorafenib increased sorafenib efficacy. This study lays the foundation for discovering new anti-HCC mechanism based on thrombin. BX-2 can be used as an anti-HCC drug lead for further research.

Wang X, Peng H, Zhang G, Li Z, Du Z, Peng B, Cao P. ADNP is associated with immune infiltration and radiosensitivity in hepatocellular carcinoma for predicting the prognosis. BMC Med Genomics 2023; 16:178. [PMID: 37525242 PMCID: PMC10391866 DOI: 10.1186/s12920-023-01592-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2023] [Accepted: 06/26/2023] [Indexed: 08/02/2023] Open
Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is one of the most lethal diseases due to its high faculty of invasiveness and metastasis. Activity-dependent neuroprotective protein (ADNP) has been regarded as an oncogene in bladder cancer and ovarian cancer. However, the role of ADNP in the regulation of tumor immune response, development, and treatment resistance in HCC remains unknown and is worth exploring. METHODS The correlation between ADNP and prognosis, immune cell infiltration, immune checkpoints, chemokines, tumor mutation burden, microsatellite instability, and genomic mutation of pan-cancer cohorts in The Cancer Genome Atlas was analyzed. ADNP expression in HCC cell lines, HCC and the adjacent normal tissues was measured by western blotting and immunochemistry. Nomogram was constructed to predict the survival of patients with HCC based on the ADNP expression and significant clinical characteristics. The potential biological functions and impacts on radiotherapy of ADNP in HCC cell lines were verified by vitro experiments. RESULTS ADNP was upregulated in most cancers and patients with elevated ADNP expression were related to poor survival in several types of cancers including HCC. Functional enrichment analysis showed ADNP participated in the pathways correlated with coagulation cascades and DNA double strand break repair. Further, ADNP exhibited a negative correlation with the immune score, stromal score, estimated score, and chemokines, and a positive correlation with cancer-associated fibroblasts, myeloid-derived suppressor cells, neutrophils, regulatory T cells, and endothelial cells. Immunochemistry and western blotting results demonstrated ADNP was up-regulated in HCC. Vitro experiments verified that suppressing the ADNP expression significantly inhibited the proliferation, invasion and migration and elevated the radiosensitivity via decreasing DNA damage repair in HCC. CONCLUSION ADNP might play an oncogene and immunosuppression role in tumor immune infiltration and response, thus influencing the prognosis. Its downregulation could attenuate the proliferation, invasion, migration, radioresistance of HCC. Our results indicated the potential of ADNP as a promising biomarker to predict the survival of HCC patients, providing a theoretical basis for novel integrative strategies.

Abstract
ABSTRACT Integrins are a family of transmembrane receptors that connect the extracellular matrix and actin skeleton, which mediate cell adhesion, migration, signal transduction, and gene transcription. As a bi-directional signaling molecule, integrins can modulate many aspects of tumorigenesis, including tumor growth, invasion, angiogenesis, metastasis, and therapeutic resistance. Therefore, integrins have a great potential as antitumor therapeutic targets. In this review, we summarize the recent reports of integrins in human hepatocellular carcinoma (HCC), focusing on the abnormal expression, activation, and signaling of integrins in cancer cells as well as their roles in other cells in the tumor microenvironment. We also discuss the regulation and functions of integrins in hepatitis B virus-related HCC. Finally, we update the clinical and preclinical studies of integrin-related drugs in the treatment of HCC.

Abstract
Hepatocellular carcinoma (HCC) ranks near the top in the global list of malignancies causing cancer-related death. Recently, combination therapy has gained popularity in treating this cancer. We tried to investigate the efficacy of combined treatment with curcumin and anti-programmed cell death-1 (anti-PD-1) in HCC. Hep3B cells were treated with different concentrations of curcumin, followed by determination of Hep3B cell proliferation and programmed cell death ligand-1 (PD-L1) expression. Then, Hep3B cells were co-cultured with peripheral blood mononuclear cells (PBMCs), after which the Hep3B cell growth and immune activity were detected following treatment with curcumin and/or anti-PD-1. Besides, we investigated the effect of transforming growth factor beta 1 (TGF-β1) on lymphocyte activation and the interaction between E1A binding protein P300 (P300), histone acetylation, TGF-β1, and thrombin. Additionally, the synergistic role of curcumin and anti-PD-1 in mouse models of HCC was studied. Curcumin retarded Hep3B cell growth and reduced surface PD-L1 expression in Hep3B cells. After co-culture of Hep3B cells and PBMCs, curcumin had a synergistic effect with anti-PD-1 to slow Hep3B cell proliferation, activate lymphocytes, inhibit immune evasion, and down-regulate TGF-β1 expression. Functionally, curcumin inhibited thrombin to reduce P300-induced histone acetylation in the TGF-β1 promoter region, and anti-PD-1 suppressed binding of PD-1 and PD-L1 to promote immune activity; the combination of the two showed better in vitro anti-cancer effects. In vivo, curcumin combined with anti-PD-1 also lowered HCC growth rate and improved the tumor microenvironment. In conclusion, the combination of curcumin and anti-PD-1 is synergistically effective in the treatment of HCC treatment.

Abstract
BACKGROUND Cancer-tumor associated macrophage (TAM)-cancer associated fibroblast (CAF) interactions are an important factor in the tumor microenvironment of hepatocellular carcinoma. MATERIALS AND METHODS Hepatic stellate cells (HSCs) were cultured with cancer cell-conditioned medium (Ca.-CM), TAM-CM and CAF-CM, and the expression of CAF markers were evaluated by RT-PCR. Whether HSCs cultured with Ca.-CM, TAM-CM and CAF-CM contributed to the enhanced malignancy of cancer cells was examined using proliferation, invasion and migration assays. Furthermore, the differences between these three types of CM were evaluated using cytokine arrays. RESULTS HSCs cultured with Ca.-CM, TAM-CM and CAF-CM showed significantly increased mRNA expression of αSMA, FAP and IL-6. All HSCs cultured with each CM exhibited significantly increased proliferation, invasion and migration of cancer cells. The osteopontin concentration was significantly higher in HSCs cultured with TAM-CM than the other CAF-CMs. Osteopontin inhibition significantly reduced osteopontin secretion from HSCs cultured with TAM-CM and suppressed the proliferation and invasion of cancer cells enhanced by HSCs cultured with TAM-CM. CONCLUSIONS We observed enhanced osteopontin secretion from TAMs, and this increased osteopontin further promoted osteopontin secretion from HSCs cultured with TAM-CM, leading to increased malignancy. For the first time, we demonstrated the importance of cancer-TAM-CAF interactions via osteopontin in hepatocellular carcinoma.

Abstract
BACKGROUND AND PURPOSE Cancer cachexia and cancer-associated thrombosis are potentially fatal outcomes of advanced cancer. Nevertheless, thrombin expression in non-small cell lung cancer (NSCLC) primary tumour tissues and the association between prognosis of NSCLC patients remain largely unknown. EXPERIMENTAL APPROACH Clinical pathological analysis was performed to determine the relationship between thrombin and tumour progression. Effects of r-hirudin and direct thrombin inhibitor peptide (DTIP) on cancer progression were evaluated. Western blotting, immunohistochemistry, and immunofluorescence were used to explore the inhibition mechanism of r-hirudin and DTIP. The therapeutic effect of the combination of DTIP and chemotherapy was determined. KEY RESULTS Thrombin expression in NSCLC tissues was closely related to clinicopathological features and the prognosis of patients. Thrombin deficiency inhibited tumour progression. The novel thrombin inhibitors, r-hirudin and DTIP, inhibited cell invasion and metastasis in vitro. They inhibited tumour growth and metastasis in orthotopic lung cancer model, inhibited cell invasion, and prolonged survival after injection of tumour cells via the tail vein. They also inhibited angiogenesis and spontaneous metastases from subcutaneously inoculated tumours. The promotion by thrombin of invasion and metastasis was abolished in PAR-1-deficient NSCLC cells. r-hirudin and DTIP inhibited tumour progression through the thrombin-PAR-1-mediated RhoA and NF-κB signalling cascades via inhibiting MMP9 and IL6 expression. DTIP potentiated chemotherapy-induced growth and metastatic inhibition and inhibited chemotherapy-induced resistance in mice. CONCLUSIONS AND IMPLICATIONS Thrombin makes a substantial contribution, together with PAR-1, to NSCLC malignancy. The anti-coagulants, r-hirudin and DTIP, could be used in anti-tumour therapy and a combination of DTIP and chemotherapy might improve therapeutic effects.

Abstract
Background Cancer cells primarily utilize aerobic glycolysis for energy production, a phenomenon known as the Warburg effect. Increased aerobic glycolysis supports cancer cell survival and rapid proliferation and predicts a poor prognosis in cancer patients. Methods Molecular profiles from The Cancer Genome Atlas (TCGA) cohort were used to analyze the prognostic value of glycolysis gene signature in human cancers. Gain- and loss-of-function studies were performed to key drivers implicated in hepatocellular carcinoma (HCC) glycolysis. The molecular mechanisms underlying Osteopontin (OPN)-mediated glycolysis were investigated by real-time qPCR, western blotting, immunohistochemistry, luciferase reporter assay, and xenograft and diethyl-nitrosamine (DEN)-induced HCC mouse models. Results Increased glycolysis predicts adverse clinical outcome in many types of human cancers, especially HCC. Then, we identified a handful of differentially expressed genes related to HCC glycolysis. Gain- and loss-of-function studies showed that OPN promotes, while SPP2, LECT2, SLC10A1, CYP3A4, HSD17B13, and IYD inhibit HCC cell glycolysis as revealed by glucose utilization, lactate production, and extracellular acidification ratio. These glycolysis-related genes exhibited significant tumor-promoting or tumor suppressive effect on HCC cells and these effects were glycolysis-dependent. Mechanistically, OPN enhanced HCC glycolysis by activating the αvβ3-NF-κB signaling. Genetic or pharmacological blockade of OPN-αvβ3 axis suppressed HCC glycolysis in xenograft tumor model and hepatocarcinogenesis induced by DEN. Conclusions Our findings reveal crucial determinants for controlling the Warburg metabolism in HCC cells and provide a new insight into the oncogenic roles of OPN in HCC. Video Abstract

Abstract
BACKGROUND To improve the early diagnosis of hepatocellular carcinoma (HCC), more effective diagnostic biomarkers are needed. A combination of biomarkers is reported to distinguish individuals with early-stage HCC from at-risk individuals. METHODS Participants in this study were recruited from six hospitals in China. Literature review was used to choose 19 candidate proteins, a case-control study in the discovery stage was used to identify five proteins (P5) that constituted a diagnostic model. In the training and validation stages, the effectiveness of P5 for detecting early-stage HCC was tested (cross-sectional study). Finally, a nested case-control study independent of the other stages was set up to evaluate the P5 in the preclinical diagnosis of HCC. FINDINGS Between February 2013 and June 2017, a total of 1396 participants were recruited. A panel of 5 proteins (P5: OPN, GDF15, NSE, TRAP5 and OPG) showed high diagnostic accuracy when differentiating the early-stage HCC from the at-risk group, with AUCs of 0·892, 0·907 and 0·852 for the training stage, validation cohort 1 and cohort 2 data sets, respectively. In the prediction set, the sensitivity of P5 for diagnosing preclinical HCC increased with time, starting from 12 months before to the time of definitive clinical diagnosis (range, 46·15% to 86·67%). INTERPRETATION The P5 panel has the potential to screen populations at high risk of developing HCC and can enable the early diagnosis of HCC. FUNDING Research supported by grants from eight funds. All sources of funding were declared at the end of the text.

Abstract
Background Hepatocellular carcinoma (HCC) is the second leading cause of cancer death worldwide. Chemotherapy is an alternative treatment for advanced HCCs, but chemo-resistance prevents cancer therapies from achieving stable and complete responses. Understanding the underlying mechanisms in chemo-resistance is critical to improve the efficacy of HCC. Methods The expression levels of Id-1 and CCN2 were detected in large cohorts of HCCs, and functional analyses of Id-1 and CCN2 were performed both in vitro and in vivo. cDNA microarrays were performed to evaluate the alterations of expression profiling of HCC cells with overexpression of CCN2. Finally, the role of downstream signaling of MAPK/Id-1 signaling pathway in oxaliplatin resistance were also explored. Results The increased expression of Id-1 and CCN2 were closely related to oxaliplatin resistance in HCC. Upregulation of CCN2 and Id-1 was independently associated with shorter survival and increased recurrence in HCC patients, and significantly enhanced oxaliplatin resistance and promoted lung metastasis in vivo, whereas knock-down of their expression significantly reversed the chemo-resistance and inhibited HCC cell stemness. cDNA microarrays and PCR revealed that Id-1 and MAPK pathway were the downstream signaling of CCN2. CCN2 significantly enhanced oxaliplatin resistance by activating the MAPK/Id-1 signaling pathway, and Id-1 could upregulate CCN2 in a positive feedback manner. Conclusions CCN2/MAPK/Id-1 loop feedback amplification is involved in oxaliplatin resistance, and the combination of oxaliplatin with inhibitor of CCN2 or MAPK signaling could provide a promising approach to ameliorating oxaliplatin resistance in HCC.

BACKGROUND The venous thromboembolism, which may be caused by increased platelet activation, is a risk factor for tumor prognosis. We determined the platelet activation status for diagnosis and predicting postoperative prognosis of hepatocellular carcinoma. METHODS We conducted a prospective study of 191 patients diagnosed with HCC at Zhongshan Hospital from April 2016 to July 2016 as well as 99 healthy people. The platelet activation status was assessed by 2 platelet markers, PAC-1 and CD62p, using flow cytometry. The patients were treated with TACE or resection and monitored for ≥6 months. The diagnostic value of marker-positive platelets was determined by the receiver operating characteristic curve and the postoperative value were analyzed using the Kaplan-Meier method and COX regression model. RESULTS All the 3 groups with high levels of marker-positive platelets were likely to be diagnosed with HCC and the PAC-1+ percentage had the best efficacy. The univariate analysis showed that the levels of PAC-1+ and CD62p+ platelets was risker factors for poor postoperative prognosis after both TACE and resection. Moreover, the multivariate analysis revealed that the level of PAC-1+ platelets was an independent risk factor for poor prognosis. CONCLUSIONS The PAC-1+ percentage of platelets is a new indicator for diagnosis and predicting postoperative prognosis.

Abstract
PURPOSE The prognostic value of tissue and serum osteopontin (OPN) in hepatocellular carcinoma (HCC) remain controversial. The aim of present meta-analysis was to evaluate the prognostic value of OPN in patients with HCC. METHODS Eligible studies were systematically searched by PubMed, EMBASE, and Google scholar. A meta-analysis of 12 studies included 2117 cases was performed to estimate the association between OPN level and overall survival (OS), disease-free survival (DFS) in HCC patients. Subgroup analyses were also performed in the meta-analysis. RESULTS The pooled data of studies showed that high OPN level was significantly associated with poor OS (hazard ratios [HR] 1.84; 95% confidence intervals [CI] 1.54-2.20; P = .000) and DFS (HR 1.67; 95% CI 1.40-1.98; P = .000) in HCC. Furthermore, in subgroup analysis, high tissue based OPN by immunohistochemistry detection and serum-based OPN by enzyme-linked immunosorbent assay (ELISA) detection were both significantly associated with OS (tissue: HR 1.88; 95% CI 1.53-2.31; P < .0001; serum: HR 2.38; 95% CI 1.58-3.59; P < .0001). Simultaneously, we also found that OPN expression was positively associated with stage (odds ratios [OR] 5.68; 95% CI 3.443-7.758), tumor size (Size≤5 cm vs >5 cm; OR 2.001; 95% CI1.036-3.867). CONCLUSION The current evidence indicates that OPN could serve as a prognostic biomarker and a potential therapeutic target for HCC.

Abstract
In the hepatocellular carcinoma (HCC) microenvironment, chemokine receptors play a critical role in tumorigenesis and metastasis. Our previous studies have found that osteopontin (OPN) is a promoter for HCC metastasis. However, the role of chemokine receptors in OPN-induced HCC metastasis remains unclear. In this study, we demonstrate that OPN is dramatically elevated in HCC tissues with metastasis and that high expression of OPN correlates with poorer overall survival and higher recurrence rate. OPN upregulates chemokine receptor expression, migration, invasion and pulmonary metastasis in HCC. We find that C-C chemokine receptor type 1 (CCR1) and C-X-C chemokine receptor type 6 (CXCR6) are the most upregulated chemokine receptors induced by OPN. CCR1 knockdown results in reduction of migration, invasion and pulmonary metastasis induced by OPN in vitro and in vivo, whereas CXCR6 knockdown does not reverse OPN-promoted migration and invasion. Moreover, OPN upregulates the expression of CCR1 through activating phosphoinositide 3-kinase (PI3K)/AKT and hypoxia-inducible factor 1α (HIF-1α) in HCC cells. Furthermore, blockade of OPN-CCR1 axis with CCR1 antagonist significantly restrains the promoting effects of OPN on HCC progression and metastasis. In human HCC tissues, OPN expression shows significantly positive correlation with CCR1 expression, and the patients with high levels of both OPN and CCR1 have the most dismal prognosis. Collectively, our results indicate that the OPN-CCR1 axis in HCC is important for accelerating tumor metastasis and that CCR1 is a potential therapeutic target for controlling metastasis in HCC patients with high OPN.

Abstract
The incidence and mortality of intrahepatic cholangiocarcinoma (ICC) are increasing worldwide in recent decades. Osteopontin (OPN) plays an important role in cancer metastasis, but its functional mechanism in ICC is not clear yet. In this study, we found that OPN level was elevated both in plasma and tumor tissues of ICC patients, which was closely related to a shorter overall survival (OS) and high probability of tumor relapse after curative resection. The gain- and loss-of-function studies determined that OPN could promote ICC growth and metastasis. OPN selectively interacted with β-Catenin and knockdown of β-Catenin abrogated the effects induced by OPN. OPN recruited MAPK1 and activated MEK-MAPK1 pathway to mediate the S675 phosphorylation of β-Catenin and nucleus accumulation, which induced the activation of Wnt signaling. Moreover, a significant correlation between OPN and β-Catenin was found in ICC tissues. OPN, β-Catenin, and their combination were independent prognostic indicator for ICC patients. In conclusion, OPN promotes ICC progression through recruiting MAPK1 and activating the Wnt/β-Catenin pathway and can serve as a novel prognostic marker and therapeutic target for ICC.

Abstract
Our previous studies have found that osteopontin (OPN) is a promoter for hepatocellular carcinoma (HCC) progression. However, the molecular mechanism by which OPN enhances HCC metastasis remains elusive. Epithelial-mesenchymal transition (EMT) of cancer cells plays a pivotal role in promoting metastatic process. In this study, we demonstrated that OPN promotes HCC metastasis by inducing an EMT-like, more aggressive cellular phenotype in vitro and in vivo. Furthermore, OPN was identified to interact with vimentin by reciprocal OPN and vimentin immunoprecipitation as well as co-immunofluorescence examination. By using deletion mutants, we found that the residues between 246 and 406 in vimentin are required for binding to OPN. Importantly, OPN significantly increased vimentin stability through inhibition of its protein degradation. Knockdown of vimentin neutralized the EMT induced by OPN both in vitro and in vivo. Moreover, a significant correlation between OPN and vimentin levels was found in clinical HCC specimens and their combination had a worse prognosis with shorter overall survival (OS) and time to recurrence (TTR). In multivariate analysis, OPN and their combination were demonstrated to be independent prognostic indicators for OS and TTR of HCC patients. Collectively, this study indicates that OPN can induce EMT of HCC cells through increasing vimentin stability, which provides more in-depth understanding about the molecular mechanisms of OPN in promoting HCC metastasis and opens tantalizing therapeutic possibilities in HCC.

CCN3 is a therapeutic target relating enhanced stemness and coagulation in hepatocellular carcinoma. Sci Rep 2017; 7:13846.

Abstract
The general prognosis of patients with hepatocellular carcinoma (HCC) remains extremely dismal, due to the high frequency of metastasis. Since 2003, our research group has explored the gene expression profiles of metastasized HCC tissue samples and identified a significant upregulation of CCN3. However, the role and precise pathological function of CCN3 remains elusive. We showed that CCN3 is associated with the poor prognosis of patients with HCC, the malignant phenotype of HCC, and vascular thrombosis. We further evaluated the negative roles of CCN3 in vitro and in vivo, and identified osteopontin (OPN), and coagulation factors tissue factor (TF) and thrombin as the leading genes downstream of CCN3, that are positively associated with HCC cell stemness. We demonstrated that overexpressed CCN3 in HCC cells leads to enhanced survival and increased number of pulmonary metastases in vivo. The elevated levels of OPN and TF were associated with signal activation of nuclear factor κB (NFκB) and extracellular signal-regulated kinases (ERK). Our findings suggest CCN3 is a potential therapeutic target that would affect the upregulation of OPN and coagulation factors, which would lead to an enhanced stemness and blood coagulation microenvironment in HCC tissue.

Abstract
MicroRNA-122 (miR-122) is implicated as a regulator of physiological and pathophysiological processes in the liver. Overexpression of Gα12 is associated with overall survival in patients with hepatocellular carcinoma (HCC). Array-based miRNA profiling was performed on Huh7 stably transfected with activated Gα12 to find miRNAs regulated by the Gα12 pathway; among them, miR-122 was most greatly repressed. miR-122 directly inhibits c-Met expression, playing a role in HCC progression. Gα12 destabilized HNF4α by accelerating ubiquitination, impeding constitutive expression of miR-122. miR-122 mimic transfection diminished the ability of Gα12 to increase c-Met and to activate ERK, STAT3, and Akt/mTOR, suppressing cell proliferation with augmented apoptosis. Consistently, miR-122 transfection prohibited tumor cell colony formation and endothelial tube formation. In a xenograft model, Gα12 knockdown attenuated c-Met expression by restoring HNF4α levels, and elicited tumor cell apoptosis but diminished Ki67 intensities. In human HCC samples, Gα12 levels correlated to c-Met and were inversely associated with miR-122. Both miR-122 and c-Met expression significantly changed in tumor node metastasis (TNM) stage II/III tumors. Moreover, changes in Gα12 and miR-122 levels discriminated recurrence-free and overall survival rates of HCC patients. Collectively, Gα12 overexpression in HCC inhibits MIR122 transactivation by inactivating HNF4α, which causes c-Met induction, contributing to cancer aggressiveness.

Abstract
High-grade gliomas constitute a group of aggressive CNS cancers that have high morbidity and mortality rates. Despite extensive research, current therapeutic approaches enable survival beyond 2 years in rare cases only. Thrombin and its main CNS target, protease-activated receptor-1, have been implicated in tumor progression and brain edema. Our aim was to study protease-activated receptor-1 (PAR-1) protein expression and thrombin-like activity levels in both in vitro and in vivo models of glioblastoma and correlate them with the volume of the surrounding edema. We measured the presence of PAR-1 protein using fluorescence immunohistochemistry and assessed thrombin activity in various glial and non-glial cell lines and in a CNS-1 glioma rat model using a thrombin-specific fluorescent assay. Thrombin activity was found to be highly elevated in various high-grade glioma cell lines as well as in non-glial malignant cell lines. In the CNS-1 glioma model, the level of PAR-1 fluorescence in the tumor was significantly elevated compared to adjacent regions of reactive gliosis or distant brain areas. The elevated level of thrombin activity observed in the high-grade glioma positively correlated with tumor-induced brain edema. In conclusion, thrombin is secreted from glioma cells and PAR-1 may be a new biological marker for high-grade gliomas.

Abstract
GOALS The aim of this study was to perform a meta-analysis to evaluate the prognostic and diagnostic significance of serum/plasma osteopontin (OPN) in hepatocellular carcinoma (HCC). BACKGROUND The prognostic and diagnostic value of serum/plasma OPN) in HCC remain controversial. STUDY Eligible studies were identified through a systematic literature search. A meta-analysis of 8 studies (4 for prognosis and 4 for diagnosis, 1399 patients) was performed to estimate the association between serum/plasma-based OPN elevation and overall survival (OS) and disease-free survival (DFS) in HCC patients, and to evaluate the accuracy of plasma OPN and α-fetoprotein (AFP) in the diagnosis of HCC. Subgroup analyses were also performed in the meta-analysis. RESULTS We found that serum/plasma-based OPN elevation was significantly associated with poor OS (HR, 1.96; 95% CI, 1.47-2.61; P<0.00001) and DFS (HR, 1.80; 95% CI, 1.43-2.26; P<0.00001) in HCC. The summary estimates for plasma OPN and AFP in diagnosing HCC in the studies included were as follows: sensitivity, 88% (95% CI, 84%-91%) versus 68% (95% CI, 63%-73%); specificity, 87% (95% CI, 83%-90%) versus 97% (95% CI, 94%-99%); diagnostic odds ratio, 62.87 (95% CI, 10.90-362.60) versus 49.09 (95% CI, 11.36-212.10); and area under SROS, 0.91 (95% CI, 0.85-0.97) versus 0.68 (95% CI, 0.45-1.03). CONCLUSIONS The current evidence indicates that serum/plasma-based OPN seems to have significant predictive ability for estimating survival in HCC, and plasma OPN has a comparable accuracy to AFP for the diagnosis of HCC, although the diagnostic value of plasma OPN for early or AFP-negative HCC remains to be assessed by further studies.

Abstract
Hepatocellular carcinoma (HCC) is one of the most frequent malignancy worldwide. The increasing incidence of HCC in the worldwide has sparked an emerging interest in prognostic markers of HCC. Osteopontin (OPN) is a secreted phosphoprotein which has been associated with progression and metastasis of HCC. Also, peritumoral macrophage (PTM) have been reported to facilitate tumor progression and metastasis. Recently, one study reported that combination of OPN with PTM may predict the prognosis of HCC after curative resection. The authors successfully identified that combination of these two markers is an independent predictor of tumor recurrence and survival in patients with HCC, especially for those with early-stage disease. These findings might support the possibility that combination of OPN and PTM levels can be a prognostic tool. However, further investigations should be conducted before tumor OPN combined with PTMs can be accepted as a valid prognostic marker in clinical practice.

Abstract
The polymeric materials have contributed significantly in the area of bioanalytical science. The functionalization of polymeric backbone after its development brings unique selectivity towards the target biomolecules. In present work, the functionalities of choice have been introduced through the ring-opening of allyl glycidyl ether. The utility of polymer is widened through derivatizations to immobilized metal ion affinity chromatographic (IMAC) material for the phosphopeptides enrichment and Reversed Phase (C-18) for the desalting prior to MALDI-MS analysis. The polymer-IMAC in addition to Fe(3+) is also immobilized with lanthanide ions like La(3+), Eu(3+), and Er(3+). The amount of Fe(3+) immobilized is determined as 0.7928 mg/g. Spherical morphology with narrow particle size dispersion is revealed by scanning electron microscopy (SEM). The surface area, pore volume and size distribution is determined by nitrogen adsorption porosimetery. The elemental composition and purity level is confirmed by energy dispersive X-ray spectroscopy (EDX) data. The derivatization to IMAC and RP is evaluated by Fourier transform infrared (FT-IR) spectroscopy. The polymer enables the efficient phosphopeptide enrichment to equal degree from casein variants, non-fat milk, egg yolk, human serum, and HeLa cell extract. The identification of phosphorylation sites can lead to the phosphorylation pathways to understand the post-translational modifications. The identification with their sequence coverage is made using Mascot and Phosphosite Plus. It is sensitive to enrich the phosphopeptides down to 2 femtomoles with very high selectivity of 1:2000 with BSA background. These attributes are linked to the higher surface area (173.1554 m(2)/g) of the designed polymer. The non-specific bindings, particularly the Fe(3+) linked acidic residues are also avoided. Four characteristic phosphopeptides (fibrinopeptide A and their hydrolytic products) from fibrinogen α-chain are identified from the human serum after the enrichment, which have link to the hepatocellular carcinoma (HCC). The proportions of fibrinogen and their phosphorylation products enriched by poly(AGE/DVB)-IMAC open new horizons in the biomarker discovery.

Osteopontin is a promoter for hepatocellular carcinoma metastasis: a summary of 10 years of studies. Front Med 2014; 8:24-32.

Abstract
In this review, we summarize the novel findings from our series of studies on the leading metastasis-related gene, osteopontin (OPN). In our previous gene expression profiling study, OPN was identified as one of the leading genes associated with the metastasis of hepatocellular carcinoma (HCC). We focused on OPN to evaluate its prognostic values and important roles in HCC metastasis. A retrospective study of large cohorts of HCC patients demonstrated that plasma OPN level was one of the leading independent prognostic factors for HCC patients, even in the early stage of HCC, and could serve as a surrogate serologic biomarker for monitoring the treatment response and tumor recurrence after HCC resection. Using both in vitro and in vivo investigations, we found that OPN has an important role in metastasis and tumor growth of HCC and is an attractive potential therapeutic target for combating HCC metastasis. We also found that OPN⁺ HCC cells have much more amplifications at chromosomal regions, and promoter polymorphisms are important in the regulation of OPN expression and tumor growth and lung metastasis of HCC.

Abstract
BACKGROUND Crosstalk between a tumor and the microenvironment plays a key role in tumor progression and metastasis. This study was performed to elucidate the prognostic significance of combining tumor-secreted osteopontin (OPN) with microenvironment-associated peritumoral macrophages (PTMs) in hepatocellular carcinoma (HCC), especially for those with early-stage disease. METHODS Tissue microarray-based immunohistochemistry was used to investigate OPN and PTMs expression in two independent cohorts consisting of 374 patients with HCC who underwent radical resection. The prognostic value for the two factors alone or in combination was investigated in these patients. RESULTS OPN combined with PTMs was an independent prognostic factor for both overall survival (OS; p < 0.0001) and time to recurrence (TTR; p = 0.003) from the learning cohort (n = 96). Their combined value for prognosis was validated in early-stage HCCs using another independent cohort (n = 278; OS, p < 0.001; TTR, p = 0.001). This combination remained significant in HCCs with low α-fetoprotein levels in both cohorts, and was predictive for early recurrence/death risk (<2 years) compared with a single marker. Only OPN+HCCs had a significant correlation of PTMs levels with OS (p = 0.01) or TTR (p = 0.011). CONCLUSIONS Tumor OPN combined with PTMs is a promising predictor of tumor recurrence and survival in patients with HCC, especially for those with early-stage disease. The interplay of OPN and PTMs represents a new insight into tumor progression and therapeutic targets for HCC.

Abstract
Osteopontin (OPN) is an acidic, glycosylated and phosphorylated protein that plays an essential role in determining the aggressiveness and oncogenic potential of several types of cancer, including lung cancer. The OPN function is highly dependent on post-translational modification (PTM) and regulation of the processes that involve OPN can be mediated through glycosylation. However, the connection between OPN function and its O-glycosylation in lung cancer cells has yet to be investigated. In the present study, this issue was addressed by studying the effects of wild-type (WT) OPN and a triple mutant (TM) of OPN, which was mutated at three O-glycosylation sites in lung cancer cells. It was shown that OPN WT rather than OPN TM induced the OPN‑mediated signaling pathway. The OPN WT expression enhanced cap-dependent protein translation, NF-κB activity and glucose uptake, whereas a reduction was observed in cells treated with OPN TM. The results clearly demonstrated that unlike OPN WT, OPN TM did not increase lung cancer cell growth and migration both in vitro and in a xenograft mouse model. Thus, results of the present study suggested that targeting OPN by introducing OPN TM may be a good strategy for treating lung cancer.

Abstract
Thrombin is the protease involved in blood coagulation. Its deregulation can lead to hemostatic abnormalities, which range from subtle subclinical to serious life-threatening coagulopathies, i.e., during septicemia. Additionally, thrombin plays important roles in many (patho)physiological conditions that reach far beyond its well-established role in stemming blood loss and thrombosis, including embryonic development and angiogenesis but also extending to inflammatory processes, complement activation, and even tumor biology. In this review, we will address thrombin's broad roles in diverse (patho)physiological processes in an integrative way. We will also discuss thrombin as an emerging major target for novel therapies.

Abstract
The cross talk between tumor cells and the surrounding peritumoral stroma has been extensively studied as a dynamic system involving the processes of hepatocarcinogenesis, tumor invasion, and metastasis in recent few decades. Besides hepatocytes, liver tumor microenvironments are generally classified into cellular and noncellular components, including hepatic stellate cells, fibroblasts, immune, endothelial, mesenchymal stem cells, together with growth factors, cytokines, extracellular matrix, hormone as well as viruses et al. The noncellular components manipulate hepatocellular carcinoma invasion and metastasis by facilitating epithelial-mesenchymal transition, increasing proteolytic activity of matrix metalloproteinases, and regulating antitumor immunity, etc. Because the main cause of death in hepatocellular carcinoma patients is tumor progression with metastasis, a better understanding of the interplay between hepatocytes and their environment during tumor metastasis may be helpful for the discovery of novel molecular targets.

Abstract
Osteopontin (OPN), first found in normal human tissue, is a secreted phosphorylated glycoprotein and one of the most important adhesion factors. Increased expression of OPN has been found in many types of tumors. OPN plays a very important role in the metastasis and recurrence of hepatocellular carcinoma (HCC). As a tumor marker, OPN may also become a new therapeutic target for cancer. This review aims to elucidate the structure and function of OPN, its role in HCC recurrence and metastasis, and the significance of OPN in HCC diagnosis and treatment.

Abstract
miR-612 suppresses local invasion and distant colonization by directly inhibiting AKT2 in HCC. MicroRNAs (miRNAs) play a critical role in tumor metastasis. In this study, we identified a set of 32 miRNAs involved in hepatocellular carcinoma (HCC) metastasis. Among them, miR-612 was shown for the first time to have inhibitory effects on HCC proliferation, migration, invasion, and metastasis. AKT2 was verified to be one of the direct targets of miR-612, through which the epithelial–mesenchymal transition (EMT) and metastasis were inhibited. The level of miR-612 in HCC patients was inversely associated with tumor size, stage, EMT, and metastasis. Of particular importance, miR-612 is involved in both the initial and final steps of the metastatic cascade, by suppressing local invasion and distant colonization. The pleiotropic roles of miR-612 in the HCC metastatic cascade suggest that it could be an effective target for both early and advanced HCC.

Abstract
UNLABELLED Osteopontin (OPN) plays a crucial role in hepatocellular carcinoma (HCC) metastasis. However, little is known about the impact of OPN polymorphisms on cancer progression. In this study, we first identified the single nucleotide polymorphisms (SNPs) in the OPN promoter region by direct sequencing in 30 HCCs, and then evaluated the prognostic values of the selected ones in two large cohorts of 826 HCC patients. The identified SNPs were functionally analyzed using in vitro and in vivo assays and their correlations with OPN levels were also evaluated. Only SNP at locus -443 and their related haplotypes (Ht2: -1748A/-616G/-443T/-155* [*indicates base deletion]; Ht3: -1748A/-616G/-443C/-155*) were significantly associated with overall survival (OS) and time to recurrence (TTR). The patients with the -443TT/TC genotype or Ht2 had a shorter OS and TTR compared with those with -443CC genotype or Ht3. This was further confirmed in the validation cohort. Moreover, this correlation remained significant in patients with small HCCs (≤5 cm). Multivariate analyses indicated that the prognostic performance of the -443 genotypes (OS, P=0.031; TTR, P=0.005) and their related haplotypes (OS, P=0.002; TTR, P=0.001) was independent of other clinicopathological factors. The Ht2 and -443TT genotype could significantly increase the promoter transcriptional activity and expression level of OPN compared with the Ht3 or -443CC genotype, and lead to an obvious increase in both in vitro invasion and in vivo tumor growth and lung metastasis of HCC cells (P<0.05). CONCLUSION The genetic variation at locus -443 of the OPN promoter plays important roles in the regulation of OPN expression and cancer progression of HCCs, which is a novel determinant and target for HCC metastasis and prognosis.

Abstract
BACKGROUND Presurgery serum osteopontin (OPN) level has been demonstrated to correlate to tumor recurrence and survival of hepatocellular carcinoma (HCC) patients. This study investigated the postoperative dynamic changes of serum OPN level and its clinical significance in HCC patients. METHODS Presurgery serum OPN levels were measured by enzyme-linked immunosorbent assay in cohort A of 179 HCC patients and were compared with the multiple controls including different kinds of liver diseases and healthy individuals. In cohort B of 110 patients with resectable HCCs, besides preoperative assays, serum OPN was monitored at 1 week, 1, and ≥2 months after operation. RESULTS The baseline presurgery serum OPN of HCC patients was significantly higher than that of the patients with the other kinds of liver diseases (p < 0.0001). The prognostic values of presurgery serum OPN level in HCC patients were further confirmed. The postsurgery OPN levels were significantly elevated within 1 week after HCC resection, then decreased at 1 month and reached the nadir later than 2 months after operations. It increased again at the time of tumor recurrence, then declined after the second removal of recurrent HCCs. Moreover, postoperative OPN in α-fetoprotein-negative and -positive HCC patients had the same changing pattern; it only correlated to liver function and C-reactive protein level. CONCLUSIONS After a transient fluctuation, serum OPN levels significantly decrease after curative resection of HCCs. Postoperative serum OPN could serve as a surrogate serologic biomarker for monitoring treatment response and tumor recurrence after HCC resection, including α-fetoprotein-negative ones.

Abstract
BACKGROUND Fibrinogen-like protein 2 (FGL2), which directly generates thrombin from prothrombin without activation of the conventional coagulation cascade, was shown to be overexpressed in various human malignant tumours. AIMS Herein, we aimed to investigate its expression pattern, biological function and mechanism of action in hepatocellular carcinoma (HCC). METHODS FGL2 expression and colocalization with fibrin was examined in 15 HCC tissues. FGL2 downregulation was performed by targeting microRNA in a HCCLM6 cell line in which FGL2 was highly expressed in xenografts of nude mice. The effects of FGL2 knockdown on tumour growth and angiogenesis were evaluated in vitro and in vivo. Cytometric bead arrays were employed to identify FGL2-regulated signalling pathways. RESULTS FGL2 was overexpressed in HCC tissues and colocalized with fibrin deposition. Knockdown of FGL2 expression in HCCLM6 cells (hFGL2(low) HCCLM6) resulted in delayed xenografts tumour growth within an observation period of 42 days and decreased vascularization, which was accompanied by decreased phosphorylation of extracellular signal-regulated kinase (ERK) and c-Jun N-terminal kinase (JNK). In vitro hFGL2(low) HCCLM6 cells exhibited decreased proliferation without significant induction of apoptosis. Overexpression of FGL2 in HCCLM6 cells or addition of recombinant hFGL2 protein induced phosphorylation of p38-MAPK and ERK1/2 involving protease-activated receptors (PARs).activation. CONCLUSIONS FGL2 contributes to HCC tumour growth and angiogenesis in a thrombin-dependent manner, and downregulation of its expression might be of therapeutic significance in HCC.

Abstract
This paper describes a novel, simple method for the highly sensitive and selective detection of thrombin using fibrinogen (Fib) and CuInS(2) quantum dots (QDs) as biosensing probes. Water-soluble near-infrared CuInS(2) QDs capped by mercaptopropionic acid (MPA) were directly synthesized by a hydrothermal method. Addition of fibrinogen to the CuInS(2) QDs solution led to the formation of a Fib-CuInS(2) QDs complex through electrostatic interactions and hydrogen bonding, and resulting in the enhancement of photoluminescence (PL) intensity and a red shift of the PL peak. Once thrombin was introduced into the Fib-CuInS(2) QDs system, it catalyzed the polymerization of the free and conjugated fibrinogen species to form insoluble fibrillar fibrin-CuInS(2) QDs agglutinates. After centrifugation, the PL intensity of the supernatants decreased upon increasing the concentration of thrombin. This Fib-CuInS(2) QDs probe provided a highly specific selectivity and a linear detection of thrombin in the range of 6.7 × 10(-11) to 3.9 × 10(-7) mol L(-1) with a detection limit (LOD) of about 8.7 × 10(-12) mol L(-1), and realized the thrombin detection in human serum samples directly. Compared with those obtained by using other nanomaterials and aptamer-based detection methods, this approach provided a lower LOD for thrombin detection. The proposed approach provides a simple and fast-responding procedure, which might hold a promising potential for application in the diagnosis of diseases associated with coagulation abnormalities and cancers.

Breast cancer metastasis suppressor 1 regulates hepatocellular carcinoma cell apoptosis via suppressing osteopontin expression. PLoS One 2012; 7:e42976.

Abstract
Breast cancer metastasis suppressor 1 (BRMS1) was originally identified as an active metastasis suppressor in human breast cancer. Loss of BRMS1 expression correlates with tumor progression, and BRMS1 suppresses several steps required for tumor metastasis. However, the role of BRMS1 in hepatocellular carcinoma (HCC) remains elusive. In this study, we found that the expression level of BRMS1 was significantly down-regulated in HCC tissues. Expression of BRMS1 in SK-Hep1 cells did not affect cell growth under normal culture conditions, but sensitized cells to apoptosis induced by serum deprivation or anoikis. Consistently, knockdown of endogenous BRMS1 expression in Hep3B cells suppressed cell apoptosis. We identified that BRMS1 suppresses osteopontin (OPN) expression in HCC cells and that there is a negative correlation between BRMS1 and OPN mRNA expression in HCC tissues. Moreover, knockdown of endogenous OPN expression reversed the anti-apoptosis effect achieved by knockdown of BRMS1. Taken together, our results show that BRMS1 sensitizes HCC cells to apoptosis through suppressing OPN expression, suggesting a potential role of BRMS1 in regulating HCC apoptosis and metastasis.

Abstract
Gastric cancer and liver cancer are among the most common malignancies and the leading causes of death worldwide, due to late detection and high recurrence rates. Today, these cancers have a heavy socioeconomic burden, for which a full understanding of their pathophysiological features is warranted to search for promising biomarkers and therapeutic targets. Osteopontin (OPN) is overexpressed in most patients with gastric and liver cancers. Over the past decade, emerging evidence has revealed a correlation of OPN level and clinicopathological features and prognosis in gastric and liver cancers, indicating its potential as an independent prognostic indicator in such patients. Functional studies have verified the potential of OPN knockdown as a therapeutic approach in vitro and in vivo. Furthermore, OPN mediates multifaceted roles in the interaction between cancer cells and the tumor microenvironment, in which many details need further exploration. OPN signaling results in various functions, including prevention of apoptosis, modulation of angiogenesis, malfunction of tumor-associated macrophages, degradation of extracellular matrix, activation of phosphoinositide 3-kinase-Akt and nuclear factor-κB pathways, which lead to tumor formation and progression, particularly in gastric and liver cancers. This editorial aims to review recent findings on alteration in OPN expression and its clinicopathological associations with tumor progression, its potential as a therapeutic target, and putative mechanisms in gastric and liver cancers. Better understanding of the implications of OPN in tumorigenesis might facilitate development of therapeutic regimens to benefit patients with these deadly malignancies.

Abstract
Metastasis is a multistage process that requires cancer cells to escape from the primary tumor, survive in the circulation, seed at distant sites and grow. Each of these processes involves rate-limiting steps that are influenced by non-malignant cells of the tumor microenvironment. There are growing evidences that tumors are sustained and promoted by inflammatory signals from the surrounding microenvironment. This review describes experimental data demonstrating the role of the inflammatory immune responses of microenvironment in metastases of hepatocellular carcinoma (HCC), points out the prospective areas for future research and possible new therapeutic approaches to control the metastasis of HCC.

Abstract
BACKGROUND Although several studies have shown that serum antithrombin III (ATIII) has anti-inflammatory effects, the prognostic value of ATIII in HCC is unknown. We investigated the influence of preoperative ATIII levels on the outcome of patients who underwent hepatectomy for hepatocellular carcinoma (HCC). METHODS Data from 440 patients (314 patients with ATIII ≥ 70 % and 126 patients with ATIII <70 %) who underwent curative hepatectomy for HCC were retrospectively collected and analyzed. To overcome bias due to the different distribution of covariates for the 2 groups, propensity score matching was performed on the patients, and outcomes were compared. RESULTS The propensity score analysis revealed that 65 patients with ATIII of ≥ 70 % (group 1) and 65 patients with ATIII of <70 % (group 2) had the same preoperative and operative characteristics (excluding the ATIII level). The overall survival rate and the disease-free survival rate was significantly higher in group 1 than in group 2 (P = 0.005 and 0.011, respectively). Multivariate analysis showed that ATIII was a significant favorable factor for overall survival and disease-free survival of patients with HCC after curative hepatectomy. CONCLUSIONS The prognosis of patients with HCC was found to be associated with preoperative antithrombin III levels. ATIII may be useful for predicting outcomes of patients with HCC after curative hepatectomy.

Abstract
Here, we describe a sensitive and specific method for thrombin detection with aptamer functionalized core-shell Fe(3)O(4)@C@Au magnetic microspheres (Au-MMPs). Firstly, Au-MMPs were synthesized through surface adsorption of gold nanoparticles onto PDDA functionalized Fe(3)O(4)@C magnetic microspheres. Then, the as-synthesized Au-MMPs were developed as new substrate for immobilization of thrombin binding aptamer (TBA) through easy formation of Au-S bond. After that, the prepared aptamer functionalized Au-MMPs (TBA@Au-MMPs) were used as effective magnetic absorbent to extract trace level of thrombin from dilute solutions. Finally, enriched thrombin was digested by trypsin and analyzed by matrix assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry. Taking advantage of the efficient affinity extraction ability of our TBA@Au-MMPs and the sensitive mass readout of MALDI-TOF, highly sensitive detection of thrombin was achieved. The limit of detection was as low as 18 fmol, corresponding to 0.36 nM thrombin in 50 μL original solution. Linear relation was observed within a concentration range from 0.5 nM to 10nM with linear correlation R(2)=0.998. Other proteins including human serum albumin (HSA), Ig G, transferrin, oval albumin (OVA) and fetal calf serum did not interfere with thrombin detection. This simple method holds great potential for analyzing, sensing, purification and preconcentration of proteins in biological fluids.

Abstract
Osteopontin (OPN) has been implicated in tumor development and progression for several years. However, the prognostic value of OPN overexpression in patients with hepatocellular carcinoma (HCC) remains controversial. We performed a meta-analysis to assess the relationship between OPN overexpression and clinical outcome of HCC. A meta-analysis of seven studies (1,158 patients) was carried out to evaluate the association between OPN and overall survival (OS) and disease-free survival (DFS) in HCC patients. The correlation between OPN and tumor vascular invasion or other invasion-related parameters was also assessed. Data were synthesized with random effect model of DerSimonian and Laird, hazard ratio (HR) or odds ratio (OR) with its 95% confidence interval (CI) was used as the effect size estimate. Our analysis results indicated that high OPN expression predicted poor OS (HR: 1.37, 95% CI: 1.21-1.55) and DFS (HR: 1.62, 95% CI: 1.24-2.11) of HCC. OPN overexpression tended to be associated with the presence of tumor vascular invasion (OR: 1.93, 95% CI: 0.97-3.84) and advanced tumor grade (OR: 1.74, 95% CI: 0.95-3.18). By this study, we conclude that OPN overexpression indicates a poor prognosis for patients with HCC, it may also have predictive potential for HCC invasion and metastasis.

Abstract
Osteopontin (OPN) is overexpressed in a variety of cancers including hepatocellular carcinoma (HCC), and is likely involved in the process of vasculogenic mimicry (VM) in some tumor cells. In this study, we explored whether OPN plays a role for VM in HCC. Metastatic MHCC97-H human HCC cells and non-metastatic Hep3B human HCC cells were compared for their abilities to establish VM. Three dimensional-culture assays showed that MHCC97-H cells but not Hep3B cells were able to form the chord-like structure that represents VM. Real-time RT-PCR arrays were used to detect gene expression profiles of the two HCC cell lines in three-dimensional culture. PCR array analyses revealed the increased expression of OPN in MHCC97-H cells forming VM compared with Hep3B cells. Small interfering RNA was employed to investigate whether OPN knockdown could influence VM, and the expression of matrix metalloproteinase (MMP)-2, MMP-9 and urokinase-type plasminogen activator (uPA) in MHCC97-H cells. OPN knockdown resulted in a significant decrease in the ability of MHCC97-H cells to form VM, which was accompanied by the down-regulation of MMP-2 and uPA expression. Furthermore, human HCC tissue samples were studied by immunohistochemistry to analyze the correlations between VM and the expression of OPN, MMP-2 and uPA. There existed significant positive correlations between VM and the expression of OPN, MMP-2 and uPA in HCC tissue samples. In conclusion, OPN is required for VM in HCC cells, and its action may be associated with activation of MMP-2 and uPA. OPN-targeted therapeutics may be useful for patients with advanced HCC.
