Oncol Lett 2022; 24:254.

Abstract
Cutaneous squamous cell carcinoma (CSCC) is one of the most common non-melanoma skin cancers worldwide. Fatty acid-binding protein 7 (FABP7) has been reported to be involved in the occurrence, development, metastasis and prognosis of various tumors. In addition, downregulated FABP7 expression was demonstrated in cutaneous malignant melanoma in a previous study. Therefore, we speculated that FABP7 may be a biomarker for CSCC diagnosis. The aim of the present study was to determine the molecular mechanism underlying the effects of FABP7 in CSCC, which may provide a new diagnostic biomarker or treatment target for CSCC. Reverse transcription-PCR, western blotting and immunohistochemistry assays were performed to detect the expression levels of FABP7 in CSCC tissues and cells. Overexpression of FABP7 was achieved in A431 and colo-16 cell lines by transfection with an overexpression vector (oeFABP7). Cell proliferation, colony formation, migration and invasion were detected by Cell Counting Kit-8, crystal violet, scratch and Transwell assays, respectively. Following FABP7 overexpression, western blotting was used to determine the expression levels of proliferation-, invasion- and Notch pathway-associated proteins, including Snail, N-cadherin, Twist, matrix metalloproteinase (MMP)-2, MMP-7, Notch 1 and Notch 3. In addition a CSCC model in nude mice was constructed. Immunohistochemistry was used to determine the expression levels of FABP7, Ki67, Notch 1 and Notch 3. It was demonstrated that FABP7 expression levels were significantly reduced in human CSCC tissues and cells compared with normal samples. Overexpression of FABP7 inhibited the proliferation, invasion and migration abilities of A431 and colo-16 cells compared with those in the negative control group. In addition, transfection with oeFABP7 reduced the expression levels of proliferation-, invasion- and Notch pathway-associated proteins compared with those in the negative control group. Overexpression of FABP7 also reduced the growth of CSCC tumors in vivo and inhibited the expression of Ki67, Notch 1 and Notch 3. Therefore, the results of the present study suggested that FABP7 may inhibit the proliferation and invasion of CSCC cells via the Notch signaling pathway.

Biomarkers and Genetic Markers of Hepatocellular Carcinoma and Cholangiocarcinoma-What Do We Already Know. Cancers (Basel) 2022; 14:cancers14061493. [PMID: 35326644 PMCID: PMC8946081 DOI: 10.3390/cancers14061493] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Revised: 03/09/2022] [Accepted: 03/13/2022] [Indexed: 02/04/2023] Open
Abstract
Simple Summary Hepatocellular carcinoma and cholangiocarcinoma continue to remain a serious threat. In this review, we describe the most common biomarkers and genetic markers currently used in the diagnosis of hepatocellular carcinoma and cholangiocarcinoma. It can be observed that biomarkers and genetic markers might be applied in various parts of diagnosis including screening tests in a high-risk group, non-invasive detection, control of therapy, treatment selection, and control of recurrence. Also, it can be seen that nowadays there is a need for more specific markers that would improve the detection in early or very early stages of both types of cancers and further research should be focused on it. Abstract Hepatocellular carcinoma (HCC) is the most common primary liver cancer with an increasing worldwide mortality rate. Cholangiocarcinoma (CCA) is the second most common primary liver cancer. In both types of cancers, early detection is very important. Biomarkers are a relevant part of diagnosis, enabling non-invasive detection and control of cancer recurrence, as well as in the application of screening tests in high-risk groups. Furthermore, some of these biomarkers are useful in controlling therapy and treatment selection. Detection of some markers presents higher sensitivity and specificity in combination with other markers when compared with a single detection. Some gene aberrations are also prognostic markers in the two types of cancers. In the following review, we discuss the most common biomarkers and genetic markers currently being used in the diagnosis of hepatocellular carcinoma and cholangiocarcinoma.

Abstract
BACKGROUND In advanced biliary tract carcinoma (BTC), the prognosis is very poor, and the overall survival is less than 1 year. This study aimed to determine the effect of neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocyte ratio (dNLR), C-reactive protein (CRP)/albumin ratio (CAR), and prognostic nutritional index (PNI) on the survival of BTC patients treated with gemcitabine/oxaliplatin (GEMOX) regimen. METHODS Data of 53 patients with advanced BTC were evaluated retrospectively. Association between inflammatory markers and 6-month PFS and 12-month OS were compared by the log-rank test. The optimal cutoff values were determined by a receiver operating characteristic (ROC) curve analysis. NLR, dNLR, CAR, and PNI were grouped based on cutoff points 1.95, 1.15, 0.57, and 33, respectively. Univariate and multivariate analyses were used to assess their prognostic values for survival. RESULTS Lower dNLR (< 1.15) was prognostic for higher 6-month PFS and 12-month OS rates, while lower NLR (< 1.95) was prognostic for higher 6-month PFS rates only. CAR and PNI did not have statistically significant effects on survival. CONCLUSIONS Pretreatment dNLR and NLR values in advanced BTC can be used as predictive markers for survival in patients undergoing the GEMOX regimen.

Abstract
Intrahepatic cholangiocarcinoma (ICC) is an aggressive biliary tract cancer (BTC) that arises from the biliary tract epithelium distal to the secondary biliary radicals. Over the past decade, significant advances have been made in the diagnosis, staging, and treatment of ICC. Emerging data have highlighted the importance of lymphadenectomy for elucidating patient prognosis as well as the at-risk nodal basins based on tumor location (de Jong et al. in J Clin Oncol 29(23):3140-3145, 2011). Several large randomized controlled trials have recently been published clarifying the role of adjuvant therapy for BTCs (Cloyd and Pawlik in J Oncol Pract 14(12):723-724, 2018). In addition, the molecular understanding of ICC pathogenesis has increased over time, leading to new potential molecular biomarkers and opening opportunities for novel targeted and immunologic therapies (Rizvi et al. in Nat Rev Clin Oncol 15(2):95-111, 2018). These recent advances serve to only improve our understanding of the optimal multidisciplinary treatment of this difficult disease.

Abstract
Matrix metalloproteinase-7 plays a pivotal role in tumour progression and metastasis as an enzyme that can degrade the cell-matrix composition and cleave peptides between alanine and leucine in various biomolecular activation processes. In this work, a Pd-functionalised carbon nanocomposite was designed as a new impedance enhancer for an amperometric sensor of MMP-7. Pd nanoparticles in the enhancer can catalyse the oxidation of 4-chloro-1-naphthol with H2O2 to generate insoluble precipitation in situ, forming high-resistance precipitation on electrodes. In addition, poorly conductive carbon nanospheres of the nanocomposite increased the precipitation resistance, further causing a dramatic increase in resistivity of the enhancer and, subsequently, a significant decrease in current. This can significantly promote the current signal difference between the biosensor treated with and without the target analyte, which is directly related to the sensitivity of the amperometric biosensor. Overall, electrochemical biosensor can sensitively detect MMP-7 in the range of 100 fg mL-1 to 100 ng mL-1 with a limit of detection for MMP-7 of 17.38 fg mL-1.

Abstract
BACKGROUND Cholangiocarcinoma (CCA) represents the second most common primary liver malignancy. The incidence rate has constantly increased over the last decades and CCA patients face a dismal prognosis with a 5-year survival rate of less than 5% for advanced stage of disease. Surgical tumor resection has remained the only potentially curative treatment option in daily practice but is often not feasible due to advanced disease stage at initial diagnosis. SUMMARY The early detection of cholangiocarcinoma is essential to provide patients with a potentially curative treatment. Furthermore, prognostic biomarkers represent a valuable tool to offer patients a tailored therapeutic approach in accordance to their life expectancy. The clinically most established biomarker carbohydrate antigen 19-9 shows only a limited diagnostic and prognostic power, encouraging the evaluation of novel biomarkers for cholangiocarcinoma in the last years. Key Massage: In this review, we assess currently available and potential future biomarkers for the diagnosis and prognosis of cholangicarcinoma.

Abstract
Intrahepatic cholangiocarcinoma (iCCA) is the second most common primary liver tumor with increasing incidence worldwide. The outcome of patients with iCCA is dismal owing to tumor's aggressiveness, late diagnosis and lack of effective treatment options. Detection of the tumor at early stages may make surgical resection, as only potential curative treatment, more feasible. Unfortunately, despite recent developments in imaging modalities and laboratory tests, the diagnosis of iCCA remains challenging and patients often present in advanced stages when surgery cannot be offered. Moreover, accurate assessment of disease burden is critical to optimize management strategy, including the use of adjuvant therapies and clinical trials. Identifying iCCA specific diagnostic and prognostic biomarkers has been a focus of interest among many investigators with a progressive increase in data on iCCA related to advances in "omics" technologies. We herein summarize iCCA biomarkers and define the molecular mechanisms underlying iCCA carcinogenesis, as well as highlight potential diagnostic and prognostic application of molecular biomarkers.

Abstract
Intrahepatic cholangiocarcinoma (iCCA) is one of the fatal gastrointestinal cancers with increasing incidence and mortality. Although surgery offers the only potential for cure in iCCA patients, the prognosis is not optimal with low overall survival rate and high disease recurrence. Hence, adjuvant therapy is generally recommended in the management of high-risk patients. Identifying factors associated with disease recurrence and survival of the iCCA patients after resection will improve understanding of disease prognosis and help in selecting patients who will benefit from surgical resection or stratifying them for clinical trials. Despite development of new methods for early detection of tumor recurrence, effective prognostic models and nomograms, and recent advances in management, significant challenges remain in improving the prognosis of iCCA patients.

Abstract
Cholangiocarcinoma (CCA) is an aggressive biliary tract malignancy arising from the epithelial bile duct. The lack of early diagnostic biomarkers as well as therapeutic measures results in severe outcomes and poor prognosis. Thus, effective early diagnostic, prognostic, and therapeutic biomarkers are required to improve the prognosis and prolong survival rates in CCA patients. Recent advancement in omics technologies combined with the integrative experimental and clinical validations has provided an insight into the underlying mechanism of CCA initiation and progression as well as clues towards novel biomarkers. This work highlights the discovery and validation of molecular markers in CCA identified through omics approaches. The possible roles of these molecules in various cellular pathways, which render CCA carcinogenesis and progression, will also be discussed. This paper can serve as a reference point for further investigations to yield deeper understanding in the complex feature of this disease, potentially leading to better approaches for diagnosis, prognosis, and therapeutics.

Abstract
Background Cholangiocarcinoma is a malignant tumor arising from the epithelium of the bile ducts. In this study, we prepared sorafenib-loaded biliary stents for potential application as drug-delivery systems for localized treatment of extrahepatic cholangiocarcinoma. Methods A sorafenib-coated metal stent was prepared using an electrospray system with the aid of poly(ɛ-caprolactone) (PCL), and then its anticancer activity was investigated using human cholangiocellular carcinoma (HuCC)-T1 cells in vitro and a mouse tumor xenograft model in vivo. Anticancer activity of sorafenib against HuCC-T1 cells was evaluated by the proliferation test, matrix metalloproteinase (MMP) activity, cancer cell invasion, and angiogenesis assay in vitro and in vivo. Results The drug-release study showed that the increased drug content on the PCL film induced a faster drug-release rate. The growth of cancer cells on the sorafenib-loaded PCL film surfaces decreased in a dose-dependent manner. MMP-2 expression of HuCC-T1 cells gradually decreased according to sorafenib concentration. Furthermore, cancer cell invasion and tube formation of human umbilical vein endothelial cells significantly decreased at sorafenib concentrations higher than 10 mM. In the mouse tumor xenograft model with HuCC-T1 cells, sorafenib-eluting PCL films significantly inhibited the growth of tumor mass and induced apoptosis of tumor cells. Various molecular signals, such as B-cell lymphoma (Bcl)-2, Bcl-2-associated death promoter, Bcl-x, caspase-3, cleaved caspase-3, Fas, signal transducer and activator of transcription 5, extracellular signal-regulated kinases, MMP-9 and pan-janus kinase/stress-activated protein kinase 1, indicated that apoptosis, inhibition of growth and invasion was cleared on sorafenib-eluting PCL films. Conclusion These sorafenib-loaded PCL films are effective in inhibiting angiogenesis, proliferation and invasion of cancer cells. We suggest that sorafenib-loaded PCL film is a promising candidate for the local treatment of cholangiocarcinoma.

Abstract
BACKGROUND Intrahepatic cholangiocarcinoma (IHCC) is a highly malignant neoplasm, but the prognostic factors of IHCC are not yet fully understood. The matrix metalloproteinases (MMPs) are known to be related to tumor viability. The aim of this study was to evaluate the prognostic significance of clinicopathological and immunohistochemical characteristics of resected IHCC. PATIENTS AND METHODS From 1996 to 2006, we surgically treated 35 patients with IHCC. Clinicopathological and immunohistochemical characteristics, including expression of MMPs, vascular endothelial growth factor, and epidermal growth factor receptor in the resected specimens, were investigated, and overall survival rates were evaluated with regard to the characteristics using univariate and multivariate analyses. RESULTS Univariate analysis revealed the significant prognostic factors to be preoperative serum CEA and CA19-9, intraoperative transfusion, tumor size, surgical margin, lymph node metastasis, invasion of portal and hepatic vein, intrahepatic metastasis, UICC stage, and expression of MMP-7. Subsequent multivariate analysis indicated that MMP-7 was an independent prognostic factor (hazard ratio (HR), 4.698; 95% confidence interval (CI), 0.057-0.866; P = 0.03) along with intrahepatic metastasis (HR, 5.694; 95% CI, 0.029-0.706; P = 0.017). CONCLUSION MMP-7 expression is associated with a poor prognosis in patients with resected IHCC.

Abstract
This study was performed to determine the prognostic role of preoperative serum carbohydrate antigen (CA) 19-9 levels in the survival of patients with cholangiocarcinoma. Articles published up to June 1(st), 2010 that evaluated preoperative CA19-9 levels and the prognosis of cholangiocarcinoma were collected for meta-analysis. The required information for calculating individual relative risk (RR) was extracted from the studies, and a combined overall RR was estimated. Nine eligible studies were included. One study dealt with extra-hepatic cholangiocarcinoma, while the other eight studies analyzed intra-hepatic cholangiocarcinoma. The mean methodological quality score was 74.1%, ranging from 65.5% to 82.5%. The overall RR for the nine studies was 1.28 (95% confidence interval = 1.10-1.46), and the Z-score for overall effect was 13.83 (P<0.001). The association between serum CA19-9 level and lymph node involvement was also assessed. The combined RR was 1.471 (95% confidence interval = 0.411-5.264) and Z-score for overall effect was 0.59 (P = 0.553). CA19-9 levels were associated significantly with the prognosis of patients with cholangiocarcinoma. This meta-analysis shows that elevation of preoperative CA19-9 levels is correlated with a poor prognosis of patients with cholangiocarcinoma. However, larger scale and randomized studies are needed to draw a more substantive conclusion.

Abstract
AIM: To determine whether the serum level of matrix metalloproteinase-7 (MMP7) has the potential to diagnosis cholangiocarcinoma from benign biliary tract diseases.
METHODS: This study was performed according to the PRoBE (a prospective-specimen-collection, retrospective-blinded-evaluation) design. A total of 187 patients with obstructive jaundice were consecutively enrolled. After the diagnostic status of these patients was ascertained, their levels of serum MMP7 were assayed and compared with serum carbohydrate antigen 19-9 (CA19-9). This was conducted in a blinded case (cholangiocarcinoma)-control (benign biliary tract disease) setup.
RESULTS: MMP7 and CA19-9 serum levels were significantly elevated in cholangiocarcinoma patients (P < 0.001). The area under the curve (AUC) from a receiver operating characteristic (ROC) curve analysis for the diagnosis of cholangiocarcinoma, using MMP7 was more accurate than CA19-9 (AUC = 0.84, 95% CI: 0.778-0.903 for MMP7 and AUC = 0.79, 95% CI: 0.708-0.868 for CA19-9). The sensitivity and specificity of serum MMP7 (cut-off value of 5.5 ng/mL) was 75% and 78%, respectively, while the sensitivity and specificity of serum CA19-9 (cut-off value of 100 U/mL) was 68% and 87%, respectively.
CONCLUSION: Serum values of MMP7 and CA19-9 appear to be useful biomarkers for differentiating cholangiocarcinoma from benign biliary tract obstructive diseases.

Abstract
UNLABELLED Cholangiocarcinoma (CCA) cells paradoxically express tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), a death ligand that, failing to kill CCA cells, instead promotes their tumorigenicity and especially the metastatic behaviors of cell migration and invasion. Second mitochondria-derived activator of caspase (smac) mimetics are promising cancer therapeutic agents that enhance proapoptotic death receptor signaling by causing cellular degradation of inhibitor of apoptosis (IAP) proteins. Our aim was to examine the in vitro and in vivo effects of the smac mimetic JP1584 in CCA. Despite JP1584-mediated loss of cellular inhibitor of apoptosis-1 (cIAP-1) and cIAP-2, TRAIL failed to induce apoptosis in KMCH-1, TFK-1, and BDEneu CCA cells; a finding consistent with a downstream block in death signaling. Because cIAP-1 and cIAP-2 also promote nuclear factor kappa B (NF-kappaB) activation by the canonical pathway, the effect of JP1584 on this signaling pathway was examined. Treatment with JP1584 inhibited TRAIL-induced NF-kappaB activation as well as TRAIL-mediated up-regulation of the NF-kappaB target gene, matrix metalloproteinase 7 (MMP7). JP1584 also reduced TRAIL-mediated CCA cell migration and invasion in vitro. Finally, in a syngeneic rat orthotopic CCA model, JP1584 administration reduced MMP7 messenger RNA levels and extrahepatic metastases. CONCLUSION : Although the smac mimetic JP1584 does not sensitize cells to apoptosis, it reduces TRAIL-induced CCA cell metastatic behavior. These data support the emerging concept that IAPs are prometastatic and represent targets for antimetastatic therapies.

Abstract
A 29-year-old man with advanced hilar cholangiocarcinoma was successfully treated with an extended right lobectomy. The carbohydrate antigen 19-9 (CA19-9) level was elevated to 939 IU/l, and the pathological findings revealed moderately differentiated tubular adenocarcinoma which involved almost the entire thickness of the hepatic duct and the adjacent liver tissue (T3) and which was associated with lymph node metastasis (N1). It was a stage IIB (T3N1M0) tubular adenocarcinoma according to UICC pathological staging. Immunohistochemical examination revealed that Ki-67, cyclin D1, and MMP-7 were positive, and 14-3-3σ and p27 were negative. The pathological and immunohistochemical findings indicated high malignant potential indicating poor prognosis. We administrated the postoperative adjunct gemcitabine combined with S-1 chemotherapy. The patient is alive without recurrence and doing well two years after surgery. We also review other reports of cholangiocarcinoma patients aged less than 30 years.

Abstract
Background Perineural invasion is a common path for cholangiocarcinoma (CCA) metastasis, and it is highly correlated with postoperative recurrence and poor prognosis. It is often an early event in a disease that is commonly diagnosed in advanced stages, and thus it could offer a timely therapeutic and diagnostic target if better understood. This article systematically reviews the progress of CCA neural invasion-related molecules. Methods Studies were identified by searching MEDLINE and PubMed databases for articles from January 1990 to December 2009, using the keywords "cholangiocarcinoma," "perineural invasion," "nerve growth factor"(NGF), "neural cell adhesion molecule" (NCAM), "matrix metalloproteinase"(MMP), "neurotransmitter," "acetylcholine" (Ach), and "transforming growth factor" (TGF)." Additional papers and book chapters were identified by a manual search of references from the key articles. Results From above we found that the molecules NGF, NCAM, MMP, Ach and TGF may have prognostic significance in, and offer clues to the mechanism of CCA neural invasion. Conclusions Cholangiocarcinoma's increasing worldwide incidence is especially poignant in view of both the lacking effective therapies, and the fact that it is commonly diagnosed in advanced stages. As CCA neural invasion often appears early, more complete characterization of its molecular pathology could lead to the identification of targets for the diagnosis and therapy of this devastating malignancy.

Abstract
In this review, we will examine various molecular biomarkers for their potential to serve as independent prognostic factors for predicting survival outcome in postoperative patients with progressive intrahepatic cholangiocarcinoma. Specific rodent models of intrahepatic cholangiocarcinoma that mimic relevant cellular, molecular, and clinical features of the human disease are also described, not only in terms of their usefulness in identifying molecular pathways and mechanisms linked to cholangiocarcinoma development and progression, but also for their potential value as preclinical platforms for suggesting and testing novel molecular strategies for cholangiocarcinoma therapy. Last, recent studies aimed at addressing the role of desmoplastic stroma in promoting intrahepatic cholangiocarcinoma progression are highlighted in an effort to underline the potential value of targeting tumor stromal components together with that of cholangiocarcinoma cells as a novel therapeutic option for this devastating cancer.

Abstract
Intraductal papillary neoplasm of the bile duct (IPNB) is characterized by exophytic proliferation of neoplastic epithelial cells with fibrovascular stalks in bile duct lumen, mucin hypersecretion, and considerable dilatation or multilocular changes of the affected bile ducts. A mucin-producing bile duct tumor is an IPNB with excessive mucin production and clinical symptoms. Herein, the phenotypes as well as the tumorigenesis and progression of IPNB are reviewed with immunohistochemical assistance. The tumors are subdivided into three phenotypes: pancreatobiliary, intestinal, and gastric. About half of IPNB cases are of the pancreatobiliary type, and the remaining half are of the intestinal type. Aberrant expression of CDX2 with MUC2 and CK20 is related to the development of intestinal metaplasia. Inactivation of P16INK4a and nuclear expression of beta-catenin are related to the development of IPNB. Decreased expression of membranous beta-catenin and E-cadherin and aberrant expression of MMP-7 and -9 and of MUC1 are related to invasion of IPNB with tubular adenocarcinoma, whereas MUC2 is involved in the invasion of IPNB with mucinous carcinoma. IPNB can be regarded as a counterpart of intraductal papillary mucinous neoplasm (IPMN) of the pancreas, particularly the main duct type. More comparative studies between IPNB and pancreatic IPMN are recommended for further analysis of these papillary neoplasms.

Abstract
Praziquantel has been used for the treatment of diseases caused by infection with various parasites. Praziquantel treatment in Opisthorchis viverrini-infected patients reduces the hepatobiliary fibrosis due to tissue resorption, however, some fibroses are irreversible. To clarify the effect of praziquantel treatment on hepatobiliary fibrosis, we examined the expression of matrix metalloproteinases (MMPs) in relation to fibrolysis on praziquantel-treated hamsters after O. viverrini acute infection (AI) for 21 days and chronic infection (CI) for 4 months. The reduction rate of hydroxyproline content in the livers of the AI group with 6-month praziquantel treatment (71%) was higher than that of corresponding praziquantel-treated CI group (13%), similar to the decrease in the thickness of peribiliary fibrosis. Hepatic mRNA levels of collagen I significantly decreased compared with untreated control after praziquantel treatment both in AI and CI groups. Expression of collagen III significantly decreased in the AI group but unchanged in the CI group. MMP-9 and MMP-13 (except 3 months in CI group) levels significantly decreased in both groups. Notably, expression of MMP-7 level increased at 1 and 6 months in both AI and CI groups, respectively. MMP-2 level did not change in both groups. Gelatinase activity of MMPs-2 and -9 was associated with their transcriptional levels. Tissue inhibitors of MMP (TIMP)-1 and TIMP-2 significantly decreased in the AI group, whereas TIMP-1 levels did not change and TIMP-2 level was significantly increased in CI group. Praziquantel treatment increased the expression of TNF-alpha in both groups, suggesting an association with MMP-7 expression. TGF-beta expression was significantly increased only in the CI group indicating its may involve in TIMPs expression. These results suggest that in animals with chronic O. viverrini infection, praziquantel treatment induces the expression of TGF-beta, and TIMPs and resultant inhibition of MMP activity, leading to slow resorption of hepatic fibrosis.

Abstract
Cholangiocarcinoma (CC) is a rare, malignant neoplasm that can develop from any site within the intrahepatic or extrahepatic biliary tree. Although the key steps of cholangiocarcinogenesis remain unknown, it has been hypothesized that CC may develop through two key premalignant precursor lesions: biliary intraepithelial neoplasia (BilIN) and intraductal papillary neoplasm of the bile duct (IPNB). These lesions probably are analogous to pancreatic intraepithelial neoplasia and intraductal papillary mucinous neoplasm, respectively. This article outlines the molecular basis of cholangiocarcinogenesis through the BilIN and IPNB pathways. It highlights the genetic mutations that alter cellular proliferation, tumor suppression, and impairment of critical mucinous, cell-adhesion, and matrix proteins.

Abstract
Matrix metalloproteinase-9 (MMP-9) is an important enzyme in tumor invasion and metastasis in malignant tumors, including cholangiocarcinoma (CC). Tumor necrosis factor-alpha (TNF-alpha), a proinflammatory cytokine, was recently reported to induce the up-regulation of MMP-9 in cultured CC cells. We examined whether cyclooxygenase-2 (COX-2) and prostaglandin-E2 (PGE2), another endogenous tumor promoter, are involved in the up-regulation of MMP-9 in CC using CC tissue specimens and a CC cell line, HuCCT-1. MMP-9 and COX-2 were immunohistochemically expressed in 58% and 89% of 110 CC cases, respectively; the expression of MMP-9 and COX-2 was correlated (r = 0.32, P = 0.00072). Using zymography, latent MMP-9 was detectable in all cases and active MMP-9 was detected in 24% of cases of the CC specimens. The TNF-alpha/TNF-receptor 1 (TNF-R1) interaction induced MMP-9 production and activation, as well as COX-2 overexpression and PGE2 production, and increased the migration of CC cells. MMP-9 up-regulation was inhibited by COX inhibitors, antagonists of EP2/4 (receptors of PGE2), and COX-1 and COX-2 siRNAs. Inhibitors of both MMP-9 and MMP-9 siRNA treatment abrogated the increase in the migration of CC cells induced by TNF-alpha. In conclusion, we propose a novel signaling pathway of MMP-9 up-regulation in CC cells such that TNF-alpha induces the activation of COX-2 and PGE2 via TNF-R1 followed by the up-regulation of MMP-9 via the PGE2 (EP2/4) receptor.

Abstract
The liver fluke Opisthorchis viverrini is endemic in southeastern Asia, and causes cholangiocarcinoma and liver fibrosis. We investigated the time profile of the expression of matrix metalloproteinases (MMPs) and tissue inhibitors of MMPs (TIMPs) in relation to peribiliary fibrosis in O. viverrini-infected hamsters. Hepatic mRNA expression of MMPs, TIMPs, cytokines and collagens I and III was assessed by quantitative reverse transcription-PCR. Zymography and immunohistochemistry were also used to examine MMPs-2 and -9 expression. After infection, an increase of peribiliary fibrosis was time-dependent. Opisthorhis viverrini-induced gene expression in hamster liver, with increased mRNA expression levels of IL-1beta, TNF-alpha, TGF-beta, and collagens I and III, was observed at 21 days p.i. Expression of MMPs-2, -13 and -14 and TIMPs-1 and -3 genes, was significantly higher at 1 month, and maximal levels of most MMPs (MMPs-2, -9, -13 and -14) were observed at 2 months p.i. The cytoplasmic levels of MMP-2 and MMP-9 were similar to mRNA expression. Immunohistochemistry revealed that MMP-9 was expressed mainly in the cytoplasm of inflammatory cells at the invasive front of the fibrous area. In contrast, the highest levels of mRNA expression of TIMPs-2 and -3, and TGF-beta were observed 10 months p.i. Concentration of TIMP-2 protein in the plasma correlated with its transcriptional level (r=0.320, P=0.040). Peribiliary fibrosis correlated positively with liver hydroxyproline content (r=0.846, P<0.001), plasma hydroxyproline concentration (r=0.770, P<0.001), plasma TIMP-2 level (r=0.335, P=0.046), and mRNA expression levels of MMP-7 (r=0.511, P=0.006), TIMP-1 (r=0.320, P=0.040), TIMP-2 (r=0.428, P=0.026), and TIMP-3 (r=0.553, P=0.003). This study suggests that expression of MMPs is associated with an inflammatory reaction in the early phase and TIMPs expression at the late phase may contribute to both fibrosis and liver injury. MMPs and TIMPs may serve as diagnostic markers for the severity of O. viverrini-induced liver injury.

Abstract
The worldwide incidence of cholangiocarcinoma (CC) is steadily rising, with the incidence in United Kingdom (UK) now exceeding 1000 cases per year. It is an aggressive malignancy typified by unresponsiveness to the existing chemotherapy and radiotherapy regimes in the vast majority of cases. Surgery offers the only hope of a cure, though post-operative disease recurrence is common, with 5-year survival rates of less than 25% following resection. Developments in molecular techniques and improved understanding of the basis of carcinogenesis in CC has led to examination of the role of biomarkers in predicting poor outcome. This systematic review examines published evidence relating to the prognostic significance of these molecular markers in CC. Of the molecular markers which have been investigated to date, p53 mutation, cyclins, proliferation indices, mucins, CA19-9, CRP and aneuploidy appear to hold significant potential as predictors of outcome in CC. These and other biomarkers may themselves represent novel therapeutic targets for CC.

Abstract
BACKGROUND/AIMS Specific markers are required for early detection and diagnosis of intrahepatic cholangiocarcinoma (ICC); however, the tumour markers currently in use are not specific for ICC. METHODS We compared an ICC cDNA library with that of hepatocellular carcinoma (HCC) by serial analysis of gene expression (SAGE). The expression patterns in each were confirmed by quantitative real-time reverse transcriptase-polymerase chain reaction (RT-PCR), immunoblotting and immunohistochemical analysis of 74 samples including 16 ICC samples. RESULTS A comparison of the two libraries revealed distinct gene expression patterns for each type of liver cancer. In addition to the known tumour markers, we detected nine novel genes associated with ICC. By comparing the mean transcript abundance in the ICC library with those in other libraries, including gastric, colon, prostate and breast cancer, together with our RT-PCR results, we identified three genes as specific markers of ICC: biglycan, insulin-like growth factor-binding protein 5 and claudin-4. Immunoblotting and immunohistochemical analyses showed that claudin-4 was highly expressed in ICC. Moreover, discrimination analysis revealed that a combination of these genes could be used to distinguish ICC from HCC or metastatic adenocarcinoma. CONCLUSIONS We identified novel marker genes of ICC that are potentially useful for the diagnosis of liver cancer.

Abstract
Cholangiocarcinoma of the perihilar, hilar, and extrahepatic bile ducts (collectively referred to as the large bile ducts) is an intractable disease, and a papillary phenotype and well-differentiated histologic grade have been proposed as indicators of a favorable prognosis after surgical resection. In this study, we examined the significance of matrix metalloproteinases (MMPs) in cholangiocarcinoma with respect to clinicopathologic features. We subjected 66 surgically resected specimens of cholangiocarcinoma of the large bile ducts to clinicopathologic examination, including postoperative survival, papillary phenotype, and immunohistochemical expression of MMP-2,-7, -9, and membrane type 1 MMP (MT1-MP). Nonneoplastic biliary epithelium did not express these 4 MMPs, whereas cholangiocarcinoma frequently expressed MMP-2 (33.9%), -7 (75.8%), -9 (47.5%), and MT1-MMP (54.5%). In particular, conventional (nonpapillary) cholangiocarcinoma expressed MMP-7 and MT1-MMP more frequently than papillary cholangiocarcinoma. The expression of MMP-7 and MT1-MMP significantly correlated with the nonpapillary phenotype, poorly differentiated histologic grade, perineural invasion, and advanced TNM stage. In contrast, the expression of MMP-2 and -9 was not associated with any of the clinicopathologic features. Univariate analysis of disease-specific survival revealed that a papillary phenotype and expression of MMP-7 were prognostic factors of cholangiocarcinoma, in addition to TNM stage, poorly differentiated histologic grade, perineural invasion, and microscopic margin status. Multivariate analysis showed only TNM stage to be an independent prognostic factor. Expression of MMP-7 in cholangiocarcinoma is an unfavorable postoperative prognostic factor of cholangiocarcinoma arising from the large bile ducts. Underexpression of MMPs in papillary cholangiocarcinoma might be associated with a favorable prognosis.

Abstract
BACKGROUND Two types of precursor lesions, flat-type 'biliary intraepithelial neoplasia (BilIN)' and papillary-type 'intraductal papillary neoplasm of the bile duct (IPNB)', are proposed in the tumorigenesis of intrahepatic cholangiocarcinoma (ICC) in hepatolithiasis. METHODS In this study, the participation of cancer-related molecules in the progression of these two precursor lesions was examined, using 64 hepatolithiatic livers with BilIN lesions (45 livers) and IPNB lesions (19 livers) and 10 hepatolithiatic livers without neoplastic lesions as a control. The expression of E-cadherin, beta-catenin, matrix metalloproteinase-7 (MMP-7), membrane type 1-MMP (MT1-MMP), cyclin D1 and c-myc was immunohistochemically examined. RESULTS The membranous expression of beta-catenin decreased along with the progression in both BilIN and IPNB lineages. Membranous expression of E-cadherin was significantly decreased in invasive ICC with BilIN and IPNB in comparison with non-invasive counterparts. MMP-7 and MT1-MMP were commonly expressed in invasive ICC with BilIN (100%), while non-invasive lesions (BilIN-1, -2, -3) and the IPNB lineage were only occasionally and weakly positive for these molecules. Cyclin D1 and c-myc, target molecules of Wnt signalling, were frequently positive in the IPNB lineage (65 and 54% respectively), and interestingly nuclear beta-catenin staining, reflecting activation of Wnt signalling, was observed only in the IPNB lineage (22%) (P<0.05). CONCLUSIONS Decreased membranous expression of beta-catenin and E-cadherin is an early event in the tumorigenesis of both BilIN and IPNB lineages. The expression of MMP-7 and MT1-MMP was closely associated with invasive growth of the BilIN lineage. The Wnt signalling pathway may play an important role in the tumorigenesis of the IPNB lineage.

Abstract
AIMS Matrix metalloproteinases (MMPs) have various functions that play roles in carcinoma development. In this study, we investigated the expression of two representative MMPs, MMP-7 and MMP-11, in papillary thyroid carcinomas. METHODS We immunohistochemically investigated the expression of these MMPs in 196 cases of papillary carcinoma. RESULTS A high level of MMP-7 expression was observed in 56 cases (28.3%). The expression level was significantly decreased in cases showing large tumour, N positivity, large pT and poor differentiation. MMP-11 expression was high in 119 cases (60.1%). The expression level was inversely related to tumour size, N factor, pT factor, pN factor, extrathyroid extension, and poor differentiation. CONCLUSIONS In contrast to other MMPs, MMP-7 and MMP-11 are inversely linked to aggressive characteristics of papillary thyroid carcinoma and their down-regulations may even be a marker of poor prognosis in patients.

Abstract
BACKGROUND We performed hepatectomy without lymph node (LN) dissection for intrahepatic cholangiocarcinoma (ICC) limited to the peripheral region of the liver, and hepatectomy with extrahepatic bile duct resection and regional LN dissection for any types of ICC extending to the hepatic hilum. Surgical outcomes were evaluated to elucidate the prognostic factors that influence patient survival with respect to intrahepatic recurrence. METHODS Forty-one patients underwent resection of ICC with no macroscopic evidence of residual cancer. RESULTS Significant risk factors for poorer survival included preoperative jaundice (P = 0.0115), serum CA19-9 levels >37 U/ml (P = 0.0089), tumor diameter >4.5 cm (P = 0.017), ICC extending to the hepatic hilum (P = 0.0065), mass-forming with periductal-infiltrating type (P = 0.003), poorly differentiated adenocarcinoma, portal vein involvement (P = 0.0785), LN metastasis at initial hepatectomy (P < 0.0001), and positive surgical margin (P = 0.023). Intrahepatic recurrence, which was the predominant manner of recurrence, was detected in 20 patients (74.1%). Patients with intrahepatic recurrence had a significantly high incidence of high serum CA19-9 levels (>37 U/ml; P = 0.0006), preoperative jaundice (P = 0.0262), ICC extended to the hepatic hilum (P = 0.0349), large tumors (>4.5 cm; P = 0.0351), portal vein involvement (P = 0.0423), and LN metastasis at initial hepatectomy (P = 0.009) compared with disease-free patients. The multiple logistic regression analysis revealed that preoperative CA19-9 elevation and obstructive jaundice influenced intrahepatic recurrence of ICC. CONCLUSIONS Although LN metastasis is a significant prognostic factor, the most obvious recurrence pattern after surgery was intrahepatic recurrence, which could be predicted preoperatively by a combination of elevated serum CA19-9 levels and manifestation of obstructive jaundice.

Abstract
AIM: To assess the effects of obstructive cholestasis on a wider range of gene expression using microarray technology.
METHODS: Male C57BL/6J mice underwent common bile duct ligation (BDL) and were matched with pair-fed sham-operated controls. After 7 d, the animals were sacrificed and total RNA was isolated from livers and kidneys. Equal amounts of RNA from each tissue were pooled for each group and hybridized to Affymetrix GeneChip®MG-U74Av2 containing a total of 12 488 probe sets. Data analysis was performed using GeneSpring®6.0 software. Northern analysis and immunofluorescence were used for validation.
RESULTS: In sham-operated and BDL mice, 44 and 50% of 12 488 genes were expressed in livers, whereas 49 and 51% were expressed in kidneys, respectively. Seven days after BDL, 265 liver and 112 kidney genes with GeneOntology annotation were up-regulated and 113 liver and 36 kidney genes were down-regulated in comparison with sham-operated controls. Many genes were commonly regulated in both tissues and metabolism-related genes represented the largest functional group.
CONCLUSION: Following BDL, microarray analysis reveals a broad range of gene alterations in both liver and kidney.

Abstract
Molecular markers can provide additional information to traditional histomorphological evaluation for the assessment of tumor progression and predicting the likelihood of invasion and metastasis in various types of malignancies. We studied the association of E-cadherin, matrix metalloproteinases (MMPs), and tissue inhibitors of metalloproteinase with the progression and metastasis of hepatocellular carcinoma. Tissue microarray including six normal livers, 14 cirrhotic livers, 39 macroregenerative nodules, 16 dysplastic nodules, 22 grade I hepatocellular carcinomas, 43 grade II hepatocellular carcinomas, seven grade III hepatocellular carcinomas, and 10 metastatic hepatocellular carcinomas were stained immunohistochemically with antibodies against MMPs -1, -2, -3, -7, -9, tissue inhibitors of metalloproteinase-1, -2, -3, and E-cadherin. The intensities of staining were scored manually by two pathologists and verified by the Chromavision Automated Cellular Imaging System. Compared with normal liver, cirrhotic liver had significantly lower E-cadherin and tissue inhibitors of metalloproteinase-1 but higher MMP-1 and -7, which suggest a more favorable environment for tumor invasion and metastasis. Grade I and grade II hepatocellular carcinomas demonstrated high E-cadherin and decreased MMP-3 and -9, which may explain the rarity of extrahepatic metastasis in low-grade hepatocellular carcinomas despite the high circulatory volume of the liver. The histological progression from dysplastic nodule to well-differentiated hepatocellular carcinoma and to less differentiated tumors was associated with a gradual decrease in tissue expression of E-cadherin, tissue inhibitors of metalloproteinase-2 and -3. Metastatic hepatocellular carcinomas showed significantly lower level of tissue inhibitors of metalloproteinase-1, -2, -3 but higher level of MMP-7. These data suggest that tissue expression of E-cadherin, certain MMPs, and tissue inhibitors of metalloproteinases could be useful markers to predict the progression and metastasis of hepatocellular carcinoma.

Abstract
Scirrhous hepatocellular carcinoma (SHCC) is a rare variation of HCC, for which characteristics of tumor cells and the fibrotic stroma have not been clarified in detail. The present study was therefore carried out to elucidate cytological features of tumor and stromal cells and components of the stromal extracellular matrix in 15 SHCC patients undergoing hepatectomy without preoperative transarterial embolization. Diagnosis was on the basis of a scirrhous histological pattern exceeding 50% of the tumor area. Expression of cytoplasmic and extracellular matrix proteins was compared among SHCC, HCC and intrahepatic cholangiocarcinoma (ICC) cases with immunohistochemical staining. The lesions could be histologically divided into radiating and sinusoidal types. Common stromal components of SHCC and ICC were collagen types I and III. There was no expression of laminin-5 in the stroma of SHCC, but it was present in almost all ICC cases. Tenascin-C expression was significantly lower in the SHCC cases and its distribution differed between SHCC and ICC. Matrix metalloproteinase-7 (MMP-7) expression was significantly higher in SHCC compared with HCC. Almost all stromal cells were alpha-smooth muscle actin-positive both in SHCC and ICC, whereas glial fibrillary acid protein (GFAP)-positive stromal cells were significantly more increased in ICC than in SHCC. SHCC clearly differed from HCC with respect to collagen types I, III and MMP-7 expression, and from ICC with regard to stromal components including laminin-5, tenascin-C and GFAP(+) stromal cells.

Abstract
OBJECTIVE To better understand the nature of the malignancy of biliary tract carcinoma and evaluate the feasibility of its prediction by gene expression profiles. METHODS AND RESULTS We explored the gene expression profiles characteristic of progression and invasiveness in the cDNA array data obtained from 37 biliary tract carcinomas (15 bile duct, 11 gallbladder, 11 of ampulla of Vater). We pre-selected 51 and 100 genes for the presence versus absence of lymph node metastasis and perineural invasion on the basis of statistical difference. To search optimized sets of genes for prediction, we applied a sequential forward feature selection, minimizing leave-one-out error rates on a k-nearest neighbor classifier. We could predict lymph node metastasis and perineural invasion with an accuracy of 94 and 100%, respectively. When the 6-stage IA cancers without perineural invasion were precluded, a marked difference in gene expression (147 gene), discriminable with 100% accuracy, was noted between positive versus negative perineural invasion, suggesting that the acquisition of invasive character is rather a later molecular pathological event in biliary tract cancer. CONCLUSION The present method provides a powerful means of classifying biliary tract carcinomas. We also suggest that perineural invasion is an important target of array databased pattern classification, which may predict patient outcomes and facilitate the determination of the extent of surgery to minimize the risk of recurrence.

Abstract
Inhibition of matrix metalloproteinases (MMPs), a family of proteolytic enzymes linked to many aspects of cancer progression, has been explored as a therapeutic goal for almost two decades. Thus far, all tested MMP inhibitors (MMPIs) have failed to reach primary end points in Phase III clinical trials, although secondary analyses suggest benefits in particular patient groups. The clinical development of these agents has been hampered by problems related to determination of effective dosages and side effects that necessitate dose lowering or drug holidays. Imaging technologies offer hope as a means to measure enzyme activity and hence effective enzyme inhibition in vivo. Meanwhile, recent results from genetic studies of both mice and man have given some clues to possible causes of musculoskeletal side effects. Future progress in the therapeutic use of MMPIs is dependent on the ability to selectively target cancer-associated MMPs at the correct stage in tumour progression and the development of surrogate markers of in vivo efficacy.
