application/pdf, At Khon Kaen in northeastern Thailand, energy metabolism in cattle was studied by a respiration trial system using a ventilated flow-through method with a face mask built with technical and financial support of Japan International Research Center for Agricultural Sciences (JIRCAS). Energy values of locally available feed resources have also been obtained from digestion and respiration trials. JIRCAS also had already completed a new ventilated head-hood apparatus for energy balance trials and started the data accumulation concerning the energy value of Pangola grass (Digitaria eriantha) with Brahman beef steers. As for the energy balance measurement technique, JIRCAS supports the establishment of feeding standard by measuring the energy requirement of domestic animals under the tropical environment and energy value of locally available feed resources in the Indochinese peninsula., 2008年帯広農村開発教育国際セミナーシンポジウム「農業と地球環境問題に関する持続的開発のための教育」報告書

- Abstract
Background: The association between diabetes mellitus (DM) and the increased risk and progression of cholangiocarcinoma (CCA) has been reported with unclear underlying mechanisms. Previous studies showed that γ-aminobutyric acid (GABA) B2 receptor (GABBR2) was upregulated in CCA cells cultured in high glucose (HG) conditions. Roles of GABA receptors in CCA progression have also been studied, but their association with DM and hyperglycemia in CCA remains unclarified., Aim: To investigate the effects of hyperglycemia on GABBR2 expression and the potential use of GABBR2 as a CCA therapeutic target., Methods: CCA cells, KKU-055 and KKU-213A, were cultured in Dulbecco Modified Eagle's Medium supplemented with 5.6 mmol/L (normal glucose, NG) or 25 mmol/L (HG) glucose and assigned as NG and HG cells, respectively. GABBR2 expression in NG and HG cells was investigated using real-time quantitative polymerase chain reaction and western blot. Expression and localization of GABBR2 in CCA cells were determined using immunocytofluorescence. GABBR2 expression in tumor tissues from CCA patients with and without DM was studied using immunohistochemistry, and the correlations of GABBR2 with the clinicopathological characteristics of patients were analyzed using univariate analysis. Effects of baclofen, a GABA-B receptor agonist, on CCA cell proliferation and clonogenicity were tested using the MTT and clonogenic assays. Phospho-kinases arrays were used to screen the affected signaling pathways after baclofen treatment, and the candidate signaling molecules were validated using the public transcriptomic data and western blot., Results: GABBR2 expression in CCA cells was induced by HG in a dose- and time-dependent manner. CCA tissues from patients with DM and hyperglycemia also showed a significantly higher GABBR2 expression compared with tumor tissues from those with euglycemia ( P < 0.01). High GABBR2 expression was significantly associated with a poorer non-papillary histological subtype but with smaller sizes of CCA tumors ( P < 0.05). HG cells of both tested CCA cell lines were more sensitive to baclofen treatment. Baclofen significantly suppressed the proliferation and clonogenicity of CCA cells in both NG and HG conditions ( P < 0.05). Phospho-kinase arrays suggested glycogen synthase kinase 3 (GSK3), β-catenin, and the signal transducer and activator of transcription 3 (STAT3) as candidate signaling molecules under the regulation of GABBR2, which were verified in NG and HG cells of the individual CCA cell lines. Cyclin D1 and c-Myc, the common downstream targets of GSK3/β-catenin and STAT3 involving cell proliferation, were accordingly downregulated after baclofen treatment., Conclusion: GABBR2 is upregulated by HG and holds a promising role as a therapeutic target for CCA regardless of the glucose condition., Competing Interests: Conflict-of-interest statement: All the authors report no relevant conflicts of interest for this article., (©The Author(s) 2023.

- Abstract
Aims: Epidemiological studies indicate diabetes mellitus and hyperglycemia as risk factors of cancers including cholangiocarcinoma (CCA). How high glucose promotes cancer development and progression, however, is still unrevealed. In this study, insight into the molecular pathway of high glucose promoting progression of CCA cells was investigated., Main Methods: Human CCA cell lines, KKU-213A and KKU-213B were cultured in normal glucose (NG; 5.56 mM) or high glucose (HG; 25 mM) and used as NG and HG cells. Forkhead box M1 (FOXM1) expression was transiently suppressed using siFOXM1. Western blotting and image analysis were employed to semi-quantitatively determine the expression levels of the specified proteins. The migration and invasion of CCA cells were revealed using Boyden chamber assays., Key Findings: All HG cells exhibited higher expression of FOXM1 than the corresponding NG cells in a dose dependent manner. Suppression of FOXM1 expression by siFOXM1 significantly reduced migration and invasion abilities of CCA cells by suppression of Slug and MMP2 expression. Inhibition of STAT3 activation using Stattic, significantly suppressed expression of FOXM1 and Slug and decreased migration and invasion abilities of HG cells. In addition, EGFR expression was significantly higher in HG cells than NG cells and increased dependently with glucose concentration. Inhibition of EGFR activation by cetuximab significantly suppressed STAT3 activation and FOXM1 expression., Significance: The mechanism of high glucose promoting progression of CCA cells was revealed to be via in part by upregulation of FOXM1 expression under EGF/EGFR and STAT3 dependent activation., (Copyright © 2021 Elsevier Inc.

- Abstract
Aberrant glycosylation is recognized as a cancer hallmark that is associated with cancer development and progression. In this study, the clinical relevance and significance of terminal fucose (TFG), by fucosyltransferase-1 (FUT1) in carcinogenesis and progression of cholangiocarcinoma (CCA) were demonstrated. TFG expression in human and hamster CCA tissues were determined using Ulex europaeus agglutinin-I (UEA-I) histochemistry. Normal bile ducts rarely expressed TFG while 47% of CCA human tissues had high TFG expression and was correlated with shorter survival of patients. In the CCA-hamster model, TFG was elevated in hyperproliferative bile ducts and gradually increased until CCA was developed. This evidence indicates the involvement of TFG in carcinogenesis and progression of CCA. The mechanistic insight was performed in 2 CCA cell lines. Suppression of TFG expression using siFUT1 or neutralizing the surface TFG with UEA-I significantly reduced migration, invasion and adhesion of CCA cells in correlation with the reduction of Akt/Erk signaling and epithelial-mesenchymal transition. A short pulse of EGF could stimulate Akt/Erk signaling via activation of EGF-EGFR cascade, however, decreasing TFG using siFUT1 or UEA-I treatment reduced the EGF-EGFR activation and Akt/Erk signaling. This evidence provides important insight into the relevant role and molecular mechanism of TFG in progression of CCA.

- Abstract
Cancer cells exhibited the aberrant cancer-associated glycans that are potential biomarkers for diagnosis and monitoring of the cancer. In this study, Sophora japonica agglutinin (SJA) was used to detect SJA-specific N-acetylgalactosamine-associated glycans (SNAG) in liver tissues and sera from cholangiocarcinoma (CCA) patients. Whether SNAG could be the diagnostic and prognostic markers for CCA was evaluated. SJA-histochemistry revealed that SNAG was undetec2 in normal bile ducts but was highly expressed in hyperplastic/dysplastic bile ducts and CCA. SNAG was negative in hepatocytes and hepatoma tissues indicating SNAG as a differential marker of CCA and hepatoma. SJA-histochemistry of CCA hamster tissues revealed the involvement of SNAG in the early pathogenesis of bile duct epithelia and CCA development. A SJA-based ELISA was successfully developed to determine SNAG in serum. Serum-SNAG from CCA patients was significantly higher than those of non-CCA control groups with the diagnostic values of 59.5% sensitivity and 73.6% specificity, comparable to those of serum CA19-9. High levels of serum SNAG (≥69AU/ml) indicated poor survival of CCA patients. Taken together, SNAG was first demonstrated here to be a glycobiomarker for diagnosis and prognosis of CCA. Association of SNAG with pathogenesis of bile ducts and CCA development were suggested. (198)., (Copyright © 2017 Elsevier B.V. All rights reserved.)

- Abstract
Cholangiocarcinoma (CCA) is an aggressive malignant tumor which is difficult to diagnose at an early stage. Because no reliable CCA specific markers are available at present, most patients are diagnosed after late clinical presentation. In many tumors, aberrant glycans participate in various steps of pathogenesis and progression. In this study, we investigated aberrant glycosylation in CCA tissues using lectin histochemistry to allow associations of specific glycans with clinicopathological features of the patients to be investigated. For this purpose, 14 lectins specific to 5 main glycan structures were used for screening. Nine lectins showed positive staining in hepatocyte sand stromal cells in liver tissues whereas three lectins, sWGA, SJA and UEA-I, had negative lectin binding to hepatocytes and normal bile duct epithelia but exhibited positive staining with CCA. sWGA was selected for further evaluation of (β-D-GlcNAc)n-glycoconjugate expressions in 44 CCA tissues. We found that sWGA- specific glycans were aberrantly expressed along with CCA development and the level of expression varied with histological types. It was highly expressed in papillary and well-differentiated types but was significantly reduced in poorly-differentiated lesions. Specific associations of sWGA-specific glycoconjugate expression with clinicopathological features or overall survival of patients were not apparent in this cohort study.
