Galectin-9 suppresses growth of hepatocellular carcinoma in vivo
ABSTRACT: Galectin-9 suppresses growth of Li-7 cells, a cell line of human hepatocellular carcinoma, in xenograft model analysis. Micro RNA expression in xenografts of Li-7 cells, a cell line of hepatocellular carcinoma, with or without administration of galectin-9 were assessed.
Project description:Galectin-9 suppresses growth of Li-7 cells, a cell line of human hepatocellular carcinoma, in vitro study. Micro RNA expression of Li-7 cells, a cell line of hepatocellular carcinoma, with or without administration of galectin-9 were assessed in vitro.
Project description:The miRNAs expression was markedly altered with the treatment of galectin-9 in vivo and various miRNAs induced by galectin-9 also may contribute to tumor growth of cholangiocarcinoma in vivo. Using a custom microarray platform, we analyzed the expression levels of 2019 human miRNA probes in the tumorous tissues in vivo that was treated with and without galectin-9.
Project description:In isolated glomeruli by beads-perfusion methods, microRNA (miRNA) expression was analyzed in healthy C57BL/6 and B6.MRLc1 glomerulonephritis mice. The expression of 1,135 miRNAs was examined, and up-regulated or down-regulated miRNA was determined. These results provide a basical information of molecular pathology in glomerulonephritis. The glomeruli were collected from female C57BL/6 (n=3, 9-month-old, healthy control) and female B6.MRLc1 (n=3, 14-month-old, early stage of glomerulonephritis; n=3, 9-month-old, late stage of glomerulonephritis). The total RNA sample was purified, and total 1,135 microRNA expression was compared among healthy, early stage, and late stage.
Project description:The microRNAs expression was markedly altered with the MCD diet. Using a custom microarray platform, we analyzed the expression levels of 1135 mouse microRNA probes in liver tissue that were fed MCD diet.
Project description:To identify molecular biomarkers that are useful for diagnosis and its targeting treatment, we analysed expression profile of synovial sarcoma tissue. In the present study, we studied gene expression profiles comparing 11 cases of synovial sarcoma.
Project description:To identify molecular biomakers that are useful for diagnosis and its targeting treatment, we compared the gene expression profile of myxiod liposarcoma with that of normal fat tissue. In the present study, we studied about gene expression profiles comparing 6 non-preoperative myxoid liposarcoma with 3 normal fat tissue.
Project description:Microarray was performed to comprehensively examine microRNA induction in murine small intestine after exposure to total body g-irradiation. Small intestines were collected from Tlr3+/+ and Tlr3-/- mice at 0 and 6 hr after exposure to 10 Gy of total body g-irradiation. Samples were pooled from 3 mice. Total RNA was extracted and subjected to microRNA microarray analysis.
Project description:Recent studies have demonstrated that micro (mi)RNA molecules can be detected in the circulation and can serve as potential biomarkers of various diseases. This study used microarray analysis to identify aberrantly expressed circulating miRNAs in patients with type 1 autoimmune hepatitis (AIH) compared with healthy controls. Patients with well-documented and untreated AIH were selected from the National Hospital Organization (NHO)-AIH-liver-network database. They underwent blood sampling and liver biopsy with inflammation grading and fibrosis staging before receiving treatment. To further confirm the microarray data, circulating expression levels of miR-21 and miR-122 were quantified by real-time quantitative polymerase chain reaction in 46 AIH patients, 40 patients with chronic hepatitis C (CHC), and 15 healthy controls. Consistent with the microarray data, serum levels of miR-21 were significantly elevated in AIH patients compared with CHC patients and healthy controls. miR-21 and miR-122 serum levels correlated with alanine aminotransferase levels. Circulating levels of miR-21 and miR-122 were significantly reduced in AIH patients with liver cirrhosis, and were inversely correlated with increased stages of fibrosis. By contrast, levels of circulating miR-21 showed a significant correlation with the histological grades of inflammation in AIH. We postulate that aberrantly expressed serum miRNAs are potential biomarkers of AIH and could be implicated in AIH pathogenesis. Alternations of miR-21 and miR-122 serum levels could reflect their putative roles in the mediation of inflammatory processes in AIH. Case-control study, steroid treatment
Project description:Comprehensive gene expression analysis in BM-resident stromal cells was performed for an overview of BM environmental change caused by total body irradiation (TBI). Total RNA samples collected from BM-resident stromal cells with or without TBI were subjected to high sensitivity DNA microarray assays Three-condition experiment: Unirradiated, 1 day after TBI and 3 days after TBI. Bone marrow stromal cells were obtained from C57BL/6 mice (n = 6) either non-irradiated or after 9.5 Gy irradiation at indicated times.
