BACKGROUND Recurrence after hepatocellular carcinoma (HCC) resection is the major obstacle to improved survival. The presence of vascular invasion (VI) in pathology specimens is a well-known unfavorable prognostic factor for HCC recurrence. Though some VI-related genes have been reported, their association with recurrence-free survival is not known. We(More)
MicroRNAs (miRNAs) play critical roles in embryonic development and are frequently deregulated in human cancers. The let-7 family members are tumor-suppressing miRNAs and are frequently downregulated in cancer cells. Lin-28 and Lin-28B are RNA-binding proteins highly expressed in embryonic tissues. Lin-28 proteins block let-7 precursors from being processed(More)
OBJECT Stathmin, an important cytosolic phosphoprotein, is involved in cell proliferation and motility. This study was performed to elucidate the role of stathmin in the progression of medulloblastoma. METHODS The expression of stathmin protein was examined by immunohistochemical staining of tumor sections obtained in 17 consecutive patients with(More)
The apolipoprotein A5 gene (APOA5 ) has been shown to play an important role in determining plasma triglyceride concentrations in humans. We describe here a novel variant, c.553G>T, in the apolipoprotein A5 gene that is associated with hypertriglyceridemia. In contrast to some other polymorphisms, which occur in non-coding regions of the gene, this variant(More)
BACKGROUND To investigate the significance of Aurora B expression in hepatocellular carcinoma (HCC). METHODS The Aurora B and Aurora A mRNA level was measured in 160 HCCs and the paired nontumorous liver tissues by reverse transcription-polymerase chain reaction. Mutations of the p53 and β-catenin genes were analyzed in 134 and 150 tumors, respectively,(More)
MATERIALS AND METHODS To elucidate the biological significance of the p53 gene expression in human hepatocellular carcinoma (HCC), the p53 protein was studied in 184 resected unifocal primary HCCs, including 102 small (-<5 cm) and 82 large HCCs (>5 cm), using immunocytochemistry. The p53 mRNA expression was analyzed in 69 cases using Northern hybridization.(More)
Collagen triple helix repeat containing-1 (CTHRC1) is a secreted glycoprotein that activates the planar cell polarity pathway of Wnt signaling. Using microarray analysis, we found that the CTHRC1 gene is overexpressed in hepatocellular carcinoma (HCC). The level of CTHRC1 mRNA was measured in 201 surgically resected HCCs using real time reverse(More)
PURPOSE KIAA0101 is a proliferating cell nuclear antigen-associated factor and involved in cell proliferation. This study is to elucidate its role in the progression, early tumor recurrence (ETR), and prognosis of hepatocellular carcinoma (HCC). EXPERIMENTAL DESIGN KIAA0101 mRNA was measured by reverse transcription-PCR in 216 resected, unifocal, primary(More)
Glypican-3 (gpc3) is the gene responsible for Simpson-Golabi-Behmel overgrowth syndrome. Previously, we have shown that GPC3 is overexpressed in hepatocellular carcinoma (HCC). In this study, we demonstrated the mechanisms for GPC3-mediated oncogenesis. Firstly, GPC3 overexpression in NIH3T3 cells gave to cancer cell phenotypes including growing in(More)
The calcium-binding protein S100P is expressed in a variety of human cancer cells and is important in cancer cell growth and invasion. Using differential display, we found S100P is overexpressed in human hepatocellular carcinoma (HCC). We examined the expression of 305 unifocal, primary HCC tumors using immunohistochemistry. The S100P protein was expressed(More)
