Zhao W, Zhang M, Wang G, Liu E, Jiang G, Zhang Y, Zhang D, Jian X, Zhao H, Zhang C, Li W. The GNAQ T96S mutation abrogates the ability of wild-type GNAQ to induce apoptosis by phosphorylating ANXA2 in natural killer/T cell lymphoma. Cancer Sci 2022; 113:2288-2296. [PMID: 35293080 PMCID: PMC9277252 DOI: 10.1111/cas.15333] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Revised: 02/14/2022] [Accepted: 02/22/2022] [Indexed: 11/28/2022] Open
Abstract
Our previous study identified Annexin A2 (ANXA2) as a Gaq-interacting partner in natural killer/T cell lymphoma (NKTCL) cells transfected with the GNAQ T96S mutation vector by immunoprecipitation and mass spectrometry; however, the detailed molecular mechanisms by which GNAQ T96S might regulate ANXA2 remain to be defined in NKTCL. Herein, we found that the GNAQ T96S mutation significantly promotes the phosphorylation of ANXA2 at the Y24 site, whereas phosphorylation of ANXA2 abolishes the ability of wild-type GNAQ to trigger cell apoptosis. Further investigation revealed that a GNAQ T96S peptide inhibitor induced apoptosis by competing with ANXA2 binding to GNAQ T96S in NKTCL cells. In vivo animal experiments demonstrated that a GNAQ T96S peptide inhibitor suppresses the growth of NKTCL cells carrying the GNAQ T96S mutation. Our current data suggest a role for GNAQ T96S/Src/ANXA2 in mediating the apoptosis of NKTCL cells, and the GNAQ T96S peptide may be a promising agent for therapy in NKTCL patients.

Sun HB, Zhang GC, Liu J, Nie CS. Long noncoding RNA LINC00184 facilitates the proliferation, metastasis, and adenine metabolism of cholangiocarcinoma via modulating hsa-miR-23b-3p/ANXA2 axis. ENVIRONMENTAL TOXICOLOGY 2021; 36:1576-1590. [PMID: 33913242 DOI: 10.1002/tox.23154] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Revised: 04/08/2021] [Accepted: 04/17/2021] [Indexed: 06/12/2023]
Abstract
The purpose of this article was to probe the mechanism underlying long noncoding RNA (lncRNA)-LINC00184 in cholangiocarcinoma development and to investigate the effects of LINC00184 on cholangiocarcinoma. We used bioinformatics to analyze the expression of LINC00184, microRNA (miR)-23b-3p and ANXA2 in cholangiocarcinoma tissues. The levels of LINC00184, miR-23b-3p, and ANXA2 were detected by qRT-PCR. Cell proliferation was tested by CCK8. Transwell assay was used to detect cell invasion and migration. The target connection between LINC00184, miR-23b-3p, or ANXA2 was probed by luciferase reporter assay. RNA pull-down method was employed to test the relationship among LINC00184/miR-23b-3p/ANXA2 in cholangiocarcinoma cells. The Pearson correlation coefficient analyzed was applied to analyze the correlation among LINC00184, miR-23b-3p, and ANXA2. LC-MS/M analysis was used to explore whether the changes of adenine metabolism was affected by LINC00184 in cholangiocarcinoma cells. We discovered that LINC00184 expression was heightened in cholangiocarcinoma patients and cells. Knockdown of LINC00184 repressed cell proliferation, invasion, migration and adenine metabolism in cholangiocarcinoma cells. miR-23b-3p was regarded as a target of LINC00184 and its depletion perversed the inhibitive influence of LINC00184 silencing on cholangiocarcinoma cells. ANXA2 was a target of miR-23b-3p and was negatively modulated by miR-23b-3p. Moreover, ANXA2 was positively modulated by LINC00184 via sponging miR-23b-3p. In short, silencing of LINC00184 suppressed cell proliferation, invasion and migration through over-expression of miR-23b-3p and reducing of ANXA2 in cholangiocarcinoma cells. These findings contribute to understanding the influences of LINC00184, miR-23b-3p, and ANXA2 on cholangiocarcinoma and provide basis for cholangiocarcinoma treatment.

Abstract
OBJECTIVE Cholangiocarcinoma (CCA) is a noxious malignancy of epithelium of the bile duct with a low response rate to chemotherapy. The epidermal growth factor receptor (EGFR) signaling pathway is implicated in the development of cancerous cells, especially CCA. In this study, we report detailed biological profiling of 13f identified from our earlier hit expansion studies. The aim of this work was to expand our understanding of 13f via more detailed investigations of its mechanism of action against KKU-100, KKU-452 and KKU-M156 CCA cells, as well as in comparison to the EGFR inhibitor Gefitinib and non-specific chemotherapeutic agents such as Cisplatin. METHODS Inhibiting EGFR-Kinase, cytotoxicity, clonogenic assay, wound healing and apoptosis were performed. Levels of total expression of EGFR and EGFR phosphorylation proteins were detected. RESULTS 13f was confirmed as an inhibitor of EGFR with an IC50 value against the tyrosine kinase of EGFR of 22 nM and IC50 values for 48 h incubation period were 1.3 ± 1.9, 1.5 ± 0.4 and 1.7 ± 1.1 µM of KKU-100, KKU-452 and KKU-M156, respectively through dose- and time-dependent induction of early apoptosis of CCA cells. The compound also suppressed the clonogenic ability of KKU-100 and KKU-M156 cells stronger than Gefitinib, while potently inhibiting EGF-stimulated CCA cell migratory activity in KKU-452 cells. It was observed that under normal conditions EGFR was activated in CCA cells. EGF-stimulated basal expression of EGFR in KKU-452 cells was suppressed following 13f treatment, which was significantly greater than that of the marketed EGFR inhibitor Gefitinib. CONCLUSION In summary, our study showed that 13f has potent anti-cancer activities including antiproliferation, clonogenic ability and migration through the modulation of EGFR signaling pathway in CCA for the first time. The compound represents an interesting starting point as a potential chemotherapeutic agent in ongoing efforts to improve response rate in CCA patients.<br />.

Abstract
Three cholangiocarcinoma (CCA) cell line-formerly named, M156, M213 and M214 have been intensively used with discrepancy of their tumor origins. They were assumed to be originated from three different donors without authentication. To verify the origins of these cell lines, the short tandem repeat (STR) analysis of the currently used cell lines, the cell stocks from the establisher and the primary tumor of a CCA patient were performed. Their phenotypic and genotypic originality were compared. The currently used 3 CCA cell lines exhibited similar STR as CCA patient ID-M213 indicating the same origin of these cells. The cell stocks from the establisher, however, revealed the same STR of M213 and M214 cells, but not M156. The misidentification of M214 and M156 is probably due to the mislabeling and cross-contamination of M213 cells during culture. These currently used cell lines were renamed as KKU-213A, -213B and -213C, for the formerly M213, M214 and M156 cells, respectively. These cell lines were established from a male with an intrahepatic mass-forming CCA stage-4B. The tumor was an adenosquamous carcinoma with the liver fluke ova granuloma in evidence. All cell lines had positive CK19 with differential CA19-9 expression. They exhibited aneuploidy karyotypes, distinct cell morphology, cell growth, cytogenetic characteristic and progressive phenotypes. KKU-213C formed a adenosquamous carcinoma, whereas KKU-213A and KKU-213B formed poorly- and well-differentiated squamous cell carcinomas in xenografted mice. mRNA microarray revealed different expression profiles among these three cell lines. The three cell lines have unique characteristics and may resemble the heterogeneity of tumor origin.

Abstract
Introduction: Cholangiocarcinoma (CCA) is a malignancy of the biliary tract. CCA generally has a low incidence worldwide but incidence is typically high in Southeast Asian countries, particularly in northeastern Thailand, where small liver-fluke (Opisthorchis viverrini) infection is endemic. CCA has a poor prognosis as most CCA patients present with advanced stages. Poor prognosis and worse outcomes are due to the lack of specific and early-stage CCA biomarkers. Areas covered: In this review, we discuss the use of CCA tissues, serum and bile samples as sources of diagnostic and prognostic markers by using -omics approaches, including genomics, epigenomics, transcriptomics and proteomics. The current state of the discovery of molecular candidates and their potential to be used as diagnostic and prognostic biomarkers for CCA are summarized and discussed. Expert opinion: Various potential molecules have been discovered, some of which have been verified as diagnostic biomarkers for CCA. However, most identified molecules require much further evaluation to help us find markers with high specificity, low cost and ease-of-use in routine diagnostic laboratories.

Metformin sensitizes cholangiocarcinoma cell to cisplatin-induced cytotoxicity through oxidative stress mediated mitochondrial pathway. Life Sci 2018; 217:155-163. [PMID: 30528773 DOI: 10.1016/j.lfs.2018.12.007] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2018] [Revised: 12/02/2018] [Accepted: 12/05/2018] [Indexed: 01/17/2023]
Abstract
AIMS Metformin (Met), an essential antidiabetic agent, shows antitumor activity in some cancers. A previous study showed that Met enhanced cytotoxic activity of cisplatin (Cis) in cholangiocarcinoma (CCA) in association with the activation of AMP-activated protein kinase and suppression of Akt-mTOR. However, these effects do not entirely explain the observed chemosensitizing effect. The present study investigated the interaction of Met and Cis over the enhanced antitumor effect. MAIN METHODS KKU-100 and KKU-M156 cells were used in the study. Cytotoxicity was assessed by acridine orange-ethidium bromide staining. Reactive oxygen species (ROS) and mitochondrial transmembrane potential (Δψm) were measured by dihydroethidium and JC-1 fluorescent methods. Cellular glutathione (GSH) and redox ratio were analyzed by enzymatic coupling assay. Proteins associated with antioxidant system and cell death were evaluated by western immunoblot. KEY FINDINGS Cytotoxicity of Cis was enhanced by Met in association with ROS formation and GSH redox stress. The antioxidants, N-acetylcysteine and TEMPOL, and MPTP inhibitor, cyclosporine, attenuated cytotoxicity in association with suppression of ROS formation and the losses of Δψm. Met in combination with Cis suppressed expression of Nrf2 and altered the expression of Bcl2 family proteins. SIGNIFICANCE The chemosensitizing effect of Met in combination with Cis is causally associated with increased oxidative stress-mediated mitochondrial cell death pathway. Met may improve the efficacy of Cis in the treatment of cancer.

Sharma MC. Annexin A2 (ANX A2): An emerging biomarker and potential therapeutic target for aggressive cancers. Int J Cancer 2018; 144:2074-2081. [PMID: 30125343 DOI: 10.1002/ijc.31817] [Citation(s) in RCA: 65] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2018] [Revised: 08/08/2018] [Accepted: 08/13/2018] [Indexed: 12/12/2022]
Abstract
ANX A2 is an important member of annexin family of proteins expressed on surface of endothelial cells (ECs), macrophages, mononuclear cells and various types of cancer cells. It exhibits high affinity binding for calcium (Ca++ ) and phospholipids. ANX A2 plays an important role in many biological processes such as endocytosis, exocytosis, autophagy, cell-cell communications and biochemical activation of plasminogen. On the cell surface ANX A2 organizes the assembly of plasminogen (PLG) and tissue plasminogen activator (tPA) for efficient conversion of PLG to plasmin, a serine protease. Proteolytic activity of plasmin is required for activation of inactive pro-metalloproteases (pro-MMPs) and latent growth factors for their biological actions. These activation steps are critical for degradation of extracellular matrix (ECM) and basement proteins (BM) for cancer cell invasion and metastasis. Increased expression of ANX A2 protein/gene has been correlated with invasion and metastasis in a variety of human cancers. Moreover, clinical studies have positively correlated ANX A2 protein expression with aggressive cancers and with resistance to anticancer drugs, shorter disease-free survival (DFS), and worse overall survival (OS). The mechanism(s) by which ANX A2 regulates cancer invasion and metastasis are beginning to emerge. Investigators used various technologies to target ANX A2 in preclinical model of human cancers and demonstrated exciting results. In this review article, we analyzed existing literature concurrent with our own findings and provided a critical overview of ANX A2-dependent mechanism(s) of cancer invasion and metastasis.

Dysregulated microRNA expression profiles in cholangiocarcinoma cell-derived exosomes. Life Sci 2018; 210:65-75.

Abstract
AIM Cholangiocarcinoma (CCA) is a malignant tumor of bile duct epithelial cells. The prognosis of CCA is poor due to lack of effective therapeutic targets and detection at an advanced stage. Exosomes are secreted nano-sized vesicles and contribute to the malignancy of several cancers via transferring their miRNAs between cells. Thus, exosomal miRNAs may serve as new therapeutic targets and potential biomarkers for CCA. MAIN METHODS Exosomes were isolated from three different CCA cell lines and normal human cholangiocyte cells, followed by miRNA profiling analysis. Potential role of dysregulated miRNA was investigated by knockdown experiment. KEY FINDINGS We found that 38 and 460 miRNAs in CCA exosomes were significantly up- and down-regulated, respectively. Of these differentially expressed miRNAs, the hsa-miR-205-5p and miR-200 family members were markedly up-regulated for 600-1500 folds, whereas the miR-199 family members and their clustered miRNA, hsa-miR-214-3p, were down-regulated for 1000-2000 folds. The expression patterns of these representative exosomal miRNAs were similar to those observed in all types of CCA cells. The target genes of the top ten most up- and down-regulated miRNAs are significantly associated with well-characterized cancer-related pathways. Consistently, knockdown of the most up-regulated miRNA, miR-205-5p, reduced KKU-M213 cell invasion and migration. SIGNIFICANCE We have demonstrated the distinct miRNA signatures in exosomes released from CCA cells, compared to normal human cholangiocyte cells. These exosomal miRNAs may have the potential to be novel therapeutic targets and biomarkers for CCA.

Abstract
BACKGROUND/AIM Early detection of disease is a pivotal factor for determining prognosis and clinical outcome of patients with cancer. As cholangiocarcinoma (CCA) is currently difficult to detect and most cases of such cancer present with late-stage disease at the time of initial diagnosis, we employed proteomic analysis of the bile to identify potential candidate biomarkers for Opisthorchis viverrini (OV)-associated CCA. MATERIALS AND METHODS Proteins in pooled bile samples from patients with CCA and OV infection, with CCA without OV infection, with OV infection but no CCA, and with neither OV infection nor CCA were separated by 15% sodium dodecyl sulfate-polyacrylamide gel electrophoresis, in-gel trypsin digestion and analyzed by liquid chromatography-tandem mass spectrometry. RESULTS According to our analysis, three proteins, namely aristaless-like homeobox1 isoform X1 (ALX1), major histocompatibility complex polypeptide-related sequence A (MICA), and uncharacterized protein C14orf105 isoform X12 were found to be potential markers for OV infection, as they were predominantly found in all OV-infected groups. Although these proteins were detected in both OV-infected patients with and without CCA, their abundance was 2.90-, 7.06-and 3.65-fold higher, respectively, in those with CCA. In patients with CCA, potential novel biomarkers wre immunoglobulin heavy chain, translocated in liposarcoma (TLS), visual system homeobox 2 (VSX2) and an unnamed protein product. CONCLUSION We provided novel information regarding potential biomarkers for OV infection and CCA. These two protein profiles could benefit diagnosis as well as monitoring of CCA.

Abstract
BACKGROUND Alterations and mutations of endo-lysosomal trafficking proteins have been associated with cancer progression. Identification and characterization of endo-lysosomal trafficking proteins in invasive cholangiocarcinoma (CCA) cells may benefit prognosis and drug design for CCA. OBJECTIVE To identify and characterize endo-lysosomal trafficking proteins in invasive CCA. METHODS A lysosomal-enriched fraction was isolated from a TNF-α induced invasive CCA cell line (KKU-100) and uninduced control cells and protein identification was performed with nano-LC MS/MS. Novel lysosomal proteins that were upregulated in invasive CCA cells were validated by real-time RT-PCR. We selected Rab7 for further studies of protein level using western blotting and subcellular localization using immunofluorescence. The role of Rab7 in CCA invasion was determined by siRNA gene knockdown and matrigel transwell assay. RESULTS Rab7 mRNA and protein were upregulated in invasive CCA cells compared with non-treated controls. Immunofluorescence studies demonstrated that Rab7 was expressed predominantly in invasive CCA cells and was localized in the cytoplasm and lysosomes. Suppression of Rab7 translation significantly inhibited TNF-α-induced cell invasion compared to non-treated control (p= 0.044). CONCLUSIONS Overexpression of Rab7 in CCA cells was associated with cell invasion, supporting Rab7 as a novel candidate for the development of diagnostic and therapeutic strategies for CCA.

Abstract
Biliary tract cancers (BTC) are aggressive malignancies associated with resistance to chemotherapy and poor prognostic rates. Therefore, novel treatment approaches are in need. Immunotherapy represents a promising breakthrough that uses a patient's immune system to target a tumor. This treatment approach has shown immense progress with positive results for selected cancers such as melanoma and nonsmall cell lung cancer. Initial preclinical data and preliminary clinical studies suggest encouraging mechanistic effects for immunotherapy in BTC offering the hope for an expanding therapeutic role for this disease. These approaches include targeted tumor antigen therapy via peptide and dendritic cell-based vaccines, allogenic cell adoptive immunotherapy, and the use of inhibitory agents targeting the immune checkpoint receptor pathway and multiple components of the tumor microenvironment. At this time demonstrating efficacy in larger clinical trials remains imperative. A multitude of ongoing trials aim to successfully translate mechanistic effects into antitumor efficacy and ultimately aim to incorporate immunotherapy into the routine management of BTC. With further research efforts, the optimization of dosing and therapeutic regimens, the identification of novel tumor antigens and a better understanding of alternative checkpoint pathway receptor expression may provide additional targets for rational combinatorial therapies which enhance the effects of immunotherapy and may offer hope for further advancing treatment options. Ultimately, the challenge remains to prospectively identify the subsets of patients with BTC who may respond to immunotherapy, and devising alternative strategies to sensitize those that do not with the hopes of improving outcomes for all with this deadly disease.

Abstract
Cholangiocarcinoma is a primary malignant tumor of the bile duct epithelium. Cholangiocarcinoma is usually detected at an advanced stage when successful treatment is no longer possible. As the tumor originates from the bile duct epithelium, bile is an ideal source of tumor biomarkers for cholangiocarcinoma. In this study, we used a quantitative proteomics approach to identify potential tumor-associated proteins in the bile fluid of six cholangiocarcinoma patients. Three different gross-appearance tumor types were used in the analysis: mass-forming type ( n = 2), periductal infiltrating type ( n = 2), and intraductal growth type ( n = 2). Two bile samples from non-cancerous patients were used as controls. Isobaric labeling, coupled with Tandem mass spectrometry, was used to quantify protein levels in the bile of cholangiocarcinoma and control patients. In all, 63 proteins were significantly increased in cholangiocarcinoma bile compared to normal bile. Alpha-1-antitrypsin was one of the overexpressed proteins that increased in cholangiocarcinoma bile samples. Immunohistochemical analysis revealed that alpha-1-antitrypsin was detected in 177 (50%) of 354 cholangiocarcinoma tissues from our Tissue Bank. Immunoblotting of 54 cholangiocarcinoma bile samples showed that alpha-1-antitrypsin was positive in 38 (70%) samples. Fecal enzyme-linked immunosorbent assay showed that alpha-1-antitrypsin level was able to distinguish cholangiocarcinoma patients from normal individuals. In conclusion, alpha-1-antitrypsin is a potential marker for early diagnosis of cholangiocarcinoma.

Abstract
Parts of Southeast Asia have the highest incidence of intrahepatic cholangiocarcinoma (CCA) in the world because of infection by the liver fluke Opisthorchis viverrini (Ov). Ov-associated CCA is the culmination of chronic Ov-infection, with the persistent production of the growth factors and cytokines associated with persistent inflammation, which can endure for years in Ov-infected individuals prior to transitioning to CCA. Isobaric labeling and tandem mass spectrometry of liver tissue from a hamster model of CCA was used to compare protein expression profiles from inflammed tissue (Ovinfected but not cancerous) versus cancerous tissue (Ov-induced CCA). Immunohistochemistry and immunoblotting were used to verify dysregulated proteins in the animal model and in human tissue. We identified 154 dysregulated proteins that marked the transition from Ov-infection to Ov-induced CCA, i.e. proteins dysregulated during carcinogenesis but not Ov-infection. The verification of dysregulated proteins in resected liver tissue from humans with Ov-associated CCA showed the numerous parallels in protein dysregulation between human and animal models of Ov-induced CCA. To identify potential circulating markers for CCA, dysregulated proteins were compared with proteins isolated from exosomes secreted by a human CCA cell line (KKU055) and 27 proteins were identified as dysregulated in CCA and present in exosomes. These data form the basis of potential diagnostic biomarkers for human Ov-associated CCA. The profile of protein dysregulation observed during chronic Ovinfection and then in Ov-induced CCA provides insight into the etiology of an infection-induced inflammation-related cancer.

Abstract
Cholangiocarcinoma (CCA) is generally a rare primary liver tumor of the bile duct with extremely poor clinical outcomes due to late diagnosis. Osteopontin (OPN) is the most abundant expressed gene in intrahepatic CCA and its involvement in tumor aggressiveness suggests it could be a useful prognostic biomarker. However, the prognostic significance of OPN expression in CCA is still controversial. We therefore immunohistochemically studied OPN expression in 354 resected CCAs and correlated the results with patient clinicopathological parameters. OPN expression was separately scored according to the percentage of cancer cells or degree of stromal tissue staining and classified as low (score 0-1) and high (score 2-3). OPN expression in CCA cells was found in 177 out of 354 patients (56.5%), whereas stroma was positive in 185 out of 354 patients (52.3%). Univariate analysis with several of the aforementioned parameters revealed that stromal but not cancer cell OPN expression was significantly associated with tumor size, tumor direct invasion into normal liver parenchyma, regional lymph node metastasis and higher staging. The combination of cancer cell and stromal OPN expression demonstrated a positive trend for linkage with lymph node metastasis. Multivariate analysis identified gender, the presence of lymphatic permeation and lymph node metastasis, but not OPN expression, as independent prognostic factors. This study confirms the presence of stromal OPN expression in tumor aggressiveness but not survival in CCA patients.

Abstract
Annexin A2, a calcium phospholipid binding protein, has been shown to play an important role in ovarian cancer metastasis. This study examined whether annexin A2 and S100A10 can be used as prognostic markers in serous ovarian cancer. ANXA2 and S100A10 gene expressions were assessed in publicly available ovarian cancer data sets and annexin A2 and S100A10 protein expressions were assessed by immunohistochemistry in a uniform cohort of stage III serous ovarian cancers (n = 109). Kaplan-Meier and Cox regression analyses were performed to assess the relationship between annexin A2 or S100A10 messenger RNA (mRNA) and protein expressions with clinical outcome. High ANXA2 mRNA levels in stage III serous ovarian cancers were associated with reduced progression-free survival (PFS; P = 0.023) and overall survival (OS; P = 0.0038), whereas high S100A10 mRNA levels predicted reduced OS (P = 0.0019). Using The Cancer Genome Atlas data sets, ANXA2 but not S100A10 expression was associated with higher clinical stage (P = 0.005), whereas both ANXA2 and S100A10 expressions were associated with the mesenchymal molecular subtype (P < 0.0001). Kaplan-Meier and Cox regression analyses showed that high stromal annexin A2 immunostaining was significantly associated with reduced PFS (P = 0.013) and OS (P = 0.044). Moreover, high cytoplasmic S100A10 staining was significantly associated with reduced OS (P = 0.027). Multivariate Cox regression analysis showed stromal annexin A2 (P = 0.009) and cytoplasmic S100A10 (P = 0.016) levels to be independent predictors of OS. Patients with high stromal annexin A2 and high cytoplasmic S100A10 expressions had a 3.4-fold increased risk of progression (P = 0.02) and 7.9-fold risk of ovarian cancer death (P = 0.04). Our findings indicate that together annexin A2 and S100A10 expressions are powerful predictors of serous ovarian cancer outcome.

Abstract
BACKGROUND Cholangiocarcinoma (CCA), or bile duct cancer, is incurable with a high mortality rate due to a lack of effective early diagnosis and treatment. Identifying cytoplasmic membrane proteins of invasive CCA that facilitate cancer progression would contribute toward the development of novel tumor markers and effective chemotherapy. MATERIALS AND METHODS An invasive CCA cell line (KKU-100) was stimulated using TNF-α and then biotinylated and purified for mass spectrometry analysis. Novel proteins expressed were selected and their mRNAs expression levels were determined by real-time RT-PCR. In addition, the expression of ALCAM was selected for further observation by Western blot analysis, immunofluorescent imaging, and antibody neutralization assay. RESULTS After comparing the proteomics profile of TNF-α induced invasive with non-treated control cells, over-expression of seven novel proteins was observed in the cytoplasmic membrane of TNF-α stimulated CCA cells. Among these, ALCAM is a novel candidate which showed significant higher mRNA- and protein levels. Immunofluorescent assay also supported that ALCAM was expressed on the cell membrane of the cancer, with increasing intensity associated with TNF-α. CONCLUSIONS This study indicated that ALCAM may be a novel protein candidate expressed on cytoplasmic membranes of invasive CCA cells that could be used as a biomarker for development of diagnosis, prognosis, and drug or antibody-based targeted therapies in the future.

Abstract
OBJECTIVE To explore the expressions of annexin A2 in bladder cancer cell lines and bladder cancer tissues, we want to find the relationship among annexin A2, drug resistance, and recurrence of bladder cancer. METHODS Our laboratory established the PUMC-91 bladder cancer cell line against gradient concentration of Adriamycin (0.3, 0.6, and 1.0 μg/mL), and we also collected 60 cases of surgically resected bladder cancer recurrent tissue samples. The tissues were classified into 2 groups according to the frequency of recurrence (<6 months and >2 years) after initial surgery. The method of immunohistochemistry was used to examine the differences in the expression of annexin A2. RESULTS There were statistical differences in annexin A2 among normal bladder epithelial cell line SV-HUC-1, PUMC-91, PUMC-91 against 0.3 μg/mL Adriamycin, and PUMC-91 against 1.0 μg/mL Adriamycin (P < .05). The expressions of Annexin A2 were found to be higher than those that recurred at >2 years (P = .002) in the bladder cancer tissues and that recurred at <6 months after initial surgery. It was also associated with invasion depth (stage) of bladder cancer, such as higher expression in T2 (invasive muscular) group than Tis (carcinoma in situ) and T1 (invasive mucosa lamina propria) groups (P = .003 and P = .000, respectively). But, it did not correlate with the differentiation (grade) of cancer cells in bladder cancer tissues (P = .593). CONCLUSION Annexin A2 can act as a valuable biomarker for predicting the drug resistance and recurrence of bladder cancer.

Abstract
Cholangiocarcinoma (CCA), a common primary malignant tumor of bile duct epithelia, is highly prevalent in Asian countries and unresponsive to chemotherapeutic drugs. Thus, a newly recognized biological entity for early diagnosis and treatment is highly needed. Exosomes are small membrane bound vesicles found in body fluids and released by most cell types including cancer cells. The vesicles contain specific subset of proteins and nucleic acids corresponding to cell types and play essential roles in pathophysiological processes. The present study aimed to assess the protein profiles of CCA-derived exosomes and their potential roles. We have isolated exosomes from CCA cells namely KKU-M213 and KKU-100 derived from Thai patients and their roles were investigated by incubation with normal human cholangiocyte (H69) cells. Exosomes were internalized into H69 cells and had no effects on viability or proliferation of the host cells. Interestingly, the exosomes from KKU-M213 cells only induced migration and invasion of H69 cells. Proteomic analysis of the exosomes from KKU-M213 cells disclosed multiple cancer related proteins that are not present in H69 exosomes. Consistent with the protein profile, treatment with KKU-M213 exosomes induced β-catenin and reduced E-cadherin expressions in H69 cells. Collectively, our results suggest that a direct cell-to-cell transfer of oncogenic proteins via exosomal pathway may be a novel mechanism for CCA progression and metastasis.

Overexpression of ANXA2 predicts adverse outcomes of patients with malignant tumors: a systematic review and meta-analysis. Med Oncol 2014; 32:392. [PMID: 25476478 DOI: 10.1007/s12032-014-0392-y] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2014] [Accepted: 11/19/2014] [Indexed: 01/23/2023]
Abstract
Accumulated evidence has indicated a correlation between annexin A2 (ANXA2) and malignancy progression. However, whether ANXA2 expression can be considered as a prognostic factor for cancer patients remains controversial. This meta-analysis aimed to explore the prognostic value of ANXA2 overexpression. A systematically comprehensive search for studies investigating the relationships between ANXA2 expression and outcome of malignant tumor patients was performed using PubMed and EMBASE. Prognostic value of ANXA2 expression in malignancy patients was evaluated regarding overall survival (OS), disease-free survival (DFS) and various clinicopathological features measured by pooled hazard ratios (HRs) or odds ratios and their 95 % confidence intervals (CIs). Fifteen studies including 2,321 patients were enrolled in the meta-analysis. Our results showed that the overexpression of ANXA2 was correlated with poor prognosis in terms of OS (HR 1.56; 95 % CI 1.24-1.97; P < 0.001) and DFS (HR 1.47; 95 % CI 1.18-1.83; P < 0.001) in patients with malignant tumors. In addition, ANXA2 overexpression was significantly associated with tumor invasion (HR 2.06; 95 % CI 1.47-2.89; P < 0.001) and lymph node metastasis (HR 2.25; 95 % CI 1.21-4.15; P = 0.01). However, when age, tumor stage, histological grade and distant metastasis were considered, no obvious association was observed. Publication bias was absent. Sensitivity analysis suggested that the results of this meta-analysis were robust. The present meta-analysis results indicated that ANXA2 overexpression might be associated with poor outcomes in patients with malignant tumors.

Abstract
Cholangiocarcinoma (CCA) is a fatal disease that is typically diagnosed late and treated ineffectively. As the morbidity and mortality rates for CCA rise markedly, patietns with CCA currently have a poor prognosis. However, if it were possible to diagnose CCA early while effective treat methods are available, CCA patients would achieve a better quality of life. Therefore, preventing the process of CCA in the early stages is an urgent problem to solve. An accurate, quick and safe method to diagnose early-stage CCA is required. The present review discusses the risk factors, status of research and certain serum markers of CCA. The sensitivity and specificity of these markers differ from each other. To explore the more accurate serum markers may be a novel direction and method for the diagnosis of CCA in laboratory medicine in the future.

Abstract
Milk fat globule epidermal growth factor 8 (MFG-E8) is a pleiotropic secreted glycoprotein to play roles in mediating immune tolerance and homeostasis maintenance and enhancing angiogenesis. To evaluate its value as a biomarker in opisthorchiasis-associated cholangiocarcinoma (CCA), the present study investigated MFG-E8 expression kinetics during the tumorigenesis in Opisthorchis viverrini infection-induced CCA, and demonstrated its expression in the tumor tissues of CCA patients and its serum level among them. During the tumorigenesis of CCA, MFG-E8 expression was increased in a time-dependent manner with the pathological processes. Absolutely higher expression of MFG-E8 messenger RNA was detected in the tumor tissues from CCA patients, compared with those in adjacent tissues. Immunobiochemical analysis showed that more than 90% CCA cases were positive and the positive reaction located in the membrane and cytoplasm of the tumor cells. Moreover, the average serum level in the CCA patients was significantly higher than that in healthy individuals and those with O. viverrini infection or other parasitosis. Correlation analysis of MFG-E8 expression with CCA clinicopathology revealed that a high expression of MFG-E8 protein was significantly bound with a poor differentiation, pathological advanced stage, and metastasis of CCA. The multivariation analysis indicated that MFG-E8 was an independent prognostic factor. In addition, short hairpin RNA-mediated MFG-E8 knockdown in CCA cell line obviously suppressed the cell proliferation. Our results strongly suggested that MFG-E8 is a promising biomarker for the diagnosis, prognosis, and therapy target of opisthorchiasis-associated CCA.

Abstract
Cholangiocarcinoma (CCA) is difficult to diagnose at an early stage and most tumors are detected at late stage where surgery or other therapy is ineffective. Many advanced techniques are applied to diagnose CCA; however, most are expensive and have varying degrees of accuracy. A less invasive and simpler procedure such as serum markers would be of substantial clinical benefit for diagnosis, monitoring, and predicting outcome for CCA patients. Recent advances in "Omics" technologies offer remarkable opportunities for establishment of biomarker-related to diseases. In this review, the potential biomarkers obtained from proteomics and glycomic studies are evaluated. Several protein markers were discovered from patient specimen, using two dimensional-differential gel electrophoresis couple with liquid chromatography tandem mass spectrometry (2D-DIGE/LC-MS-MS), matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF-MS), surface enhanced laser desorption/ionization (SELDI)-TOF-MS and capillary electrophoresis (CE)-MS, etc. Newly reported CCA-associated glyco-biomarkers were identified using lectin-assisted, monoclonal antibody-assisted or specific-target strategies. The combination between carbohydrate binding-lectin and core protein-binding mAb significantly increased the values for detection of the glyco-biomarkers for CCA. Searching for specific and sensitive molecular markers to be used for population screening is worth being evaluated. This could lead to earlier diagnosis and improve outcome. Further investigation of those biomarker functions is also of value in order to better understand the tumor biology and use them as targets for future therapeutic agents.

Abstract
A proteomic-based approach was used to search for potential markers in the plasma of hamsters in which cholangiocarcinoma (CCA) was induced by Opisthorchis viverrini infection and N-nitrosodimethylamine treatment. The plasma proteins of CCA-induced hamsters were resolved by 1-D PAGE, digested by trypsin, and analyzed by LC-MS/MS. From the criteria of protein ID scores >15 and an overexpression of at least three times across all time points, 37 proteins were selected. These overexpressed proteins largely consisted of signal transduction, structural, transport, and transcriptional proteins in the order. Among the most frequently upregulated proteins, exostosin 1 (EXT1) was selected for further validation. By western blot analysis, the EXT1 expression level in the plasma of hamster CCA was significantly higher than that of controls at 1 month and thereafter. Immunohistochemistry revealed that EXT1 was expressed at vascular walls and fibroblasts at 21 days (before tumor onset) and at 2 months (early CCA) posttreatment. Its expression was also observed in bile duct cancer cells during tumor progression at 6 months posttreatment. In the human CCA tissue microarray, EXT1 immunoreactivity was found not only in vascular walls and fibroblasts but also in bile duct cancer cells and was positive in 89.7 % (61/68) of the cases. By ELISA and immunoblotting, plasma EXT1 level was significantly higher in human CCA compared to healthy controls. In conclusion, these results suggest that increased expression of EXT1 level in the plasma might be involved in CCA genesis and might be a potential biomarker of CCA.

Cell death/proliferation roles for nc886, a non-coding RNA, in the protein kinase R pathway in cholangiocarcinoma. Oncogene 2013; 32:3722-31.

Abstract
We have recently identified nc886 (pre-miR-886 or vtRNA2-1) as a novel type of non-coding RNA that inhibits activation of protein kinase R (PKR). PKR's pro-apoptotic role through eukaryotic initiation factor 2 α (eIF2α) phosphorylation is well established in the host defense against viral infection. Paradoxically, some cancer patients have elevated PKR activity; however, its cause and consequence are not understood. Initially, we evaluated the expression of nc886, PKR and eIF2α in non-malignant cholangiocyte and cholangiocarcinoma (CCA) cells. nc886 is repressed in CCA cells and this repression is the cause of PKR's activation therein. nc886 alone is necessary and sufficient for suppression of PKR via direct physical interaction. Consistently, artificial suppression of nc886 in cholangiocyte cells activates the canonical PKR/eIF2α cell death pathway, suggesting a potential significance of the nc886 suppression and the consequent PKR activation in eliminating pre-malignant cells during tumorigenesis. In comparison, active PKR in CCA cells does not induce phospho-eIF2α nor apoptosis, but promotes the pro-survival nuclear factor-κB pathway. Thus, PKR has a dual life or death role during tumorigenesis. Similarly to the CCA cell lines, nc886 tends to be decreased but PKR tends to be activated in our clinical samples from CCA patients. Collectively from our data, we propose a tumor surveillance model for nc886's role in the PKR pathway during tumorigenesis.

Abstract
OBJECT Biomarkers for the diagnosis and prognosis of gliomas are lacking. To elucidate new diagnostic and prognostic targets, a routine method is used to evaluate differences between the protein profile of normal and tumor cells. The object of the current study was to investigate novel differentially expressed proteins and their roles in gliomas. METHODS Differences in the protein profile were compared using 2D polyacrylamide gel electrophoresis using C6 glioma cells and rat astrocytes. The mRNA and protein expression of ANXA2, PGAM1, and CALR were analyzed in glioma tissues and normal brain tissues. The expression of ANXA2 in the U87 glioma cell line was interrupted using short interfering RNA duplexes, and the role of ANXA2 in the migration and invasiveness of glioma cells was assessed. The expression of ANXA2, PGAM1, and CALR was examined further by immunohistochemical analysis using 130 glioma samples obtained in patients, and their prognostic roles in gliomas were evaluated using Kaplan-Meier and Cox regression analyses. RESULTS Significantly higher expression levels of ANXA2 and PGAM1 and a lower level of CALR were found in glioma samples than in the normal brain samples. ANXA2, PGAM1, and CALR expression correlated with the grade and survival of patients with gliomas. Multivariate analysis further revealed that ANXA2 was an independent prognostic marker for glioma. After ANXA2 expression was suppressed using short interfering RNA, U87 cells had decreased migratory and invasive capabilities in vitro. CONCLUSIONS Protein expression alterations in ANXA2, PGAM1, and CALR were found in gliomas, and ANXA2 provided a novel prognostic value.

Abstract
Liver fluke infection caused by Opisthorchis viverrini is a major public health problem in Thailand and adjacent countries. In addition to infection-associated morbidity, infection with O. viverrini and the related Clonorchis sinensis are unarguable risk factors for cholangiocarcinoma (CAA, bile-duct cancer). Here we review the pathogenesis of opisthorchiasis and the association between O. viverrini infection and bile-duct cancer, focusing on the molecular parallels between wound healing, chronic inflammation, and cancer development. We review a schema for human disease progression from fluke infection, chronic opisthorchiasis, advanced periductal fibrosis, and cholangiocarcinogenesis, and present a rationale for biomarker discovery to facilitate early intervention. We conclude by addressing post-genomic advances with a view to developing new control strategies to combat this infectious cancer.

Abstract
OBJECTIVES To investigate the association of expression status of α-enolase (ENO1) and clinicopathological outcomes of CCA patients. DESIGN AND METHODS Two-dimensional gel electrophoresis (2-DE) and mass spectrometry (MS) were used to compare differential expressed protein profiles of four human CCA cell lines and H69, a non-malignant biliary cell line, as a control. Immunohistochemical analysis was carried out in tissue-microarray of human CCA tissues (n=301). RESULTS We identified ENO1 in all CCA cell lines but not H69 by proteomics based. About 75% of patients with CCA showed over-expression of ENO1 in hyperplastic bile duct and the tumors compared with that in tumor-adjacent normal tissue counterparts. Moreover, over-expression of ENO1 is significantly associated with poor prognosis and tumor invasion of CCA patients. CONCLUSIONS ENO1 may serve as a prognostic marker to monitor the disease progression of these patients.

Abstract
OBJECTIVE Abnormal expression of Annexin A2 and S100A proteins has been reported to induce sensitivity/resistance to chemotherapy in a variety of cancers. The aim of this study was to evaluate the significance of Annexin A2 and S100A protein expression to predict response to neoadjuvant chemotherapy and prognostic significance of these protein expressions in bulky stage IB-IIA cervical cancer patients. METHODS Paired tumor samples (pre- and post-chemotherapy) were obtained from 68 patients who were treated with cisplatin-based neoadjuvant chemotherapy and radical hysterectomy at our hospital from 2006 to 2011. The expression of Annexin A2 and S100A proteins was analyzed by immunohistochemistry. RESULTS Thirty-six patients were identified as chemotherapy-response and 32 were non-response. (a). Protein expression in tumor cells: (1). Exposure of tumor cells to chemotherapy results in a change of Annexin A2 and S100A expression (P<0.05). (2). Annexin A2, S100A8 and S100A9 protein expression correlates with tumor response to chemotherapy (P<0.05). (b). Protein expression in stromal cells: (1). Expression of Annexin A2, S100A8 and S100A9 was increased, but S100A2 and S100A4 was decreased after exposure to chemotherapy (P<0.05). (2). Only S100A4 expression was associated with response to chemotherapy (P<0.05). Multivariate analysis revealed that tumor size (P=0.022), differentiation (P=0.000), Annexin A2 expression in stromal cells (P=0.009), and S100A8 expression in tumor cells (P=0.008) were independent prognostic factors for progression-free survival of cervical cancer patients. CONCLUSIONS Expression of some of the measured proteins in tumor and stromal cells correlates with chemotherapy exposure, response to therapy, and progression-free survival.

Abstract
We performed a comparative proteomic analysis of protein expression profiles in 4 cholangiocarcinoma cell lines: K100, M156, M213, and M139. The H69 biliary cell line was used as a control. Peroxiredoxin 1 and ezrin-radixin-moesin-binding phosphoprotein 50 were selected for further validation by immunohistochemistry using a cholangiocarcinoma tissue microarray (n = 301) to assess their prognostic value in this cancer. Both peroxiredoxin 1 and ezrin-radixin-moesin-binding phosphoprotein 50 were overexpressed in cholangiocarcinoma tissues compared with normal liver tissues. Of the 301 cholangiocarcinoma cases, overexpression of peroxiredoxin 1 in 103 (34.3%) was associated with an age-related effect in young patients (P = .011) and the absence of cholangiocarcinoma in lymphatic vessels and perineural tissues (P = .004 and P = .037, respectively). Expression of radixin-moesin-binding phosphoprotein 50 correlated with histopathologic type, with 180 (59.8%) of moderately or poorly differentiated tumors (P = .039) being higher, and was associated with the presence of cholangiocarcinoma in lymphatic and vascular vessels (P < .001 and P < .001, respectively). The high expression of radixin-moesin-binding phosphoprotein 50 and the low expression of peroxiredoxin 1 correlated with reduced survival by univariate analysis (P = .017 and P = .048, respectively). Moreover, the impact of peroxiredoxin 1 and radixin-moesin-binding phosphoprotein 50 expression on patient survival was an independent predictor in multivariate analyses (P = .004 and P = .025, respectively). Therefore, altered expression of peroxiredoxin 1 and radixin-moesin-binding phosphoprotein 50 may be used as prognostic markers in cholangiocarcinoma.

Abstract
AIM: To investigate the role of annexin-2 (ANXA-2) and vascular endothelial growth factor (VEGF) in promoting invasiveness of human liver cancer HepG2 cells .
METHODS: After HepG2 cells were treated with different doses of 5-fluorouracil, cell invasiveness was detected by Transwell assay, and the mRNA and protein expression of ANXA-2 and VEGF was detected by RT-PCR and Western blot, respectively.
RESULTS: The invasiveness of HepG2 cells decreased with the increase in the dose of 5-fluorouracil, with significant differences among cells treated with different doses of 5-fluorouracil (22 ± 5, 25 ± 4, 13 ± 2, 12 ± 2 vs 39 ± 7, all P < 0.05). The mRNA and protein expression of ANXA2 and VEGF in HepG2 cells decreased gradually with the increase in the dose of 5-fluorouracil (ANXA2 mRNA: 0.527 ± 0.008, 0.419 ± 0.046, 0.213 ± 0.007, 0.176 ± 0.007 vs 0.718 ± 0.008; ANXA2 protein: 0.669 ± 0.055, 0.484 ± 0.072, 0.180 ± 0.034, 0.099 ± 0.009 vs 1.236 ± 0.102; VEGF mRNA: 0.818 ± 0.016, 0.558 ± 0.101, 0.386 ± 0.009, 0.352 ± 0.017 vs 1.176 ± 0.035; VEGF protein: 0.960 ± 0.085, 0.962 ± 0.056, 0.376 ± 0.069, 0.219 ± 0.008 vs 1.124 ± 0.170, all P < 0.001). There were significant correlations between the mRNA and protein expression of ANXA2 and VEGF (rp = 0.900, rw = 0.856).
CONCLUSION: The expression of ANXA2 and VEGF in HepG2 cells decreased gradually with the increase in the dose of 5-fluorouracil. ANXA2 and VEGF may play an important role in the invasion and metastasis of hepatocellular carcinoma.
