Abstract
Cholangiocarcinoma (CCA) is acknowledged as the second most commonly diagnosed primary liver tumor and is associated with a poor patient prognosis. The present study aimed to explore the biological functions, signaling pathways and potential prognostic biomarkers involved in CCA through transcriptomic analysis. Based on the transcriptomic dataset of CCA from The Cancer Genome Atlas (TCGA), differentially expressed protein-coding genes (DEGs) were identified. Biological function enrichment analysis, including Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, was applied. Through protein-protein interaction (PPI) network analysis, hub genes were identified and further verified using open-access datasets and qRT-PCR. Finally, a survival analysis was conducted. A total of 1,463 DEGs were distinguished, including 267 upregulated genes and 1,196 downregulated genes. For the GO analysis, the upregulated DEGs were enriched in ‘cadherin binding in cell-cell adhesion’, ‘extracellular matrix (ECM) organization’ and ‘cell-cell adherens junctions’. Correspondingly, the downregulated DEGs were enriched in the ‘oxidation-reduction process’, ‘extracellular exosomes’ and ‘blood microparticles’. In regards to the KEGG pathway analysis, the upregulated DEGs were enriched in ‘ECM-receptor interactions’, ‘focal adhesions’ and ‘small cell lung cancer’. The downregulated DEGs were enriched in ‘metabolic pathways’, ‘complement and coagulation cascades’ and ‘biosynthesis of antibiotics’. The PPI network suggested that CDK1 and another 20 genes were hub genes. Furthermore, survival analysis suggested that CDK1, MKI67, TOP2A and PRC1 were significantly associated with patient prognosis. These results enhance the current understanding of CCA development and provide new insight into distinguishing candidate biomarkers for predicting the prognosis of CCA.

[PMID: 31423278 DOI: 10.3892/ol.2019.10522] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2018] [Accepted: 04/05/2019] [Indexed: 02/06/2023] Open
Abstract
The aim of the present study was to investigate the expression of epithelial mesenchymal transition (EMT)-associated proteins and their prognostic value in intrahepatic cholangiocarcinoma (ICC). The expression of six EMT-associated proteins, including E-cadherin, N-cadherin, Vimentin, Snail family transcriptional repressor 1 (Snail), Snail family transcriptional repressor 2 (Slug) and S100 calcium binding protein A4 (S100A4) was determined by immunohistochemistry in 109 patients with ICC who had received surgery. Survival analysis showed that patients with low E-cadherin expression (P<0.001) or high S100A4 (P<0.001) or Snail (P<0.001) expression had a reduced survival time. Based on the numbers of alterations in the expression of EMT-associated proteins as determined by immunohistochemical analysis, the patients were categorized as low (score, 0-3; n=75) or high (score, ≥4; n=34) EMT expression groups. The high EMT expression group was significantly associated with positive lymph node metastasis (P=0.023) and late Tumor-Node-Metastasis (TNM) stage (P<0.001). Furthermore, patients in the high EMT expression group had a significantly poorer overall survival time than those in the low EMT expression group (P<0.001). Multivariate analysis indicated that EMT status was a significant independent predictor for overall survival time (P=0.004), and was linked to surgical margin (P=0.013) and TNM stage (P<0.001). In conclusion, the reduced expression of E-cadherin and high expression of Snail and S100A4 were significantly associated with the poor survival of patients with ICC after surgery. The EMT protein expression status was associated with ICC progression, and may be considered as an independent prognostic indicator for patients with ICC.

Abstract
BACKGROUND Fluoxetine has been reported to treat anorexia nervosa (AN) caused by chemotherapy in patients with cholangiocarcinoma effectively. However, no study systematically investigated its efficacy and safety. Thus, this study will systematically assess its efficacy and safety for AN caused by chemotherapy in patients with cholangiocarcinoma. METHODS A comprehensive literature search for relevant studies will be conducted from the following databases from inception to the present: MEDILINE, EMBASE, Cochrane Library, Web of Science, PSYCINFO, Allied and Complementary Medicine Database, Chinese Biomedical Literature Database, and China National Knowledge Infrastructure. All randomized controlled trials on assessing the efficacy and safety of fluoxetine for AN caused by chemotherapy in patients with cholangiocarcinoma will be considered for inclusion in this study. RevMan V.5.3 software will be used for risk of bias assessment and statistical analysis. RESULTS This study will summarize the latest evidence of fluoxetine for AN caused by chemotherapy in patients with cholangiocarcinoma through assessing outcomes of weight, depression, anxiety, and quality of life. Additionally, any adverse events will also be analyzed. CONCLUSION The findings of this study will provide most recent evidence of fluoxetine for AN caused by chemotherapy in patients with cholangiocarcinoma. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42019131583.
