UNLABELLED Insulin-like growth factor II mRNA-binding protein 3 (IMP3) is an RNA-binding protein expressed in embryonic tissues and multiple cancers. To investigate the role of IMP3 in hepatocellular carcinoma (HCC), its protein expression in the surgically resected unifocal tumors of 377 HCC patients (296 men and 81 women) with ages ranging from 7 to 88(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)
SIRT1 is a NAD+-dependent deacetylase that plays crucial roles in many biological processes, including stress response, apoptosis, cellular metabolism, adaptation to calorie restriction, aging, and tumorigenesis. The purpose of this study is to elucidate the clinicopathological and functional significance of SIRT1 expression in hepatocellular carcinoma(More)
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 hypothesized(More)
The influence of MSI on treatment outcome of colorectal cancers remains unclear and deserves further investigation. We recruited 244 patients with stage IV sporadic colorectal cancers for our study, based on appropriate eligibility criteria. Patients were nonrandomly allocated to 2 treatment groups of either with or without high-dose 5-FU plus leucovorin(More)
Cancer cells with a high glycolytic rate have an advantage in tumor growth. Hepatocellular carcinoma (HCC) often exhibits an aberrant expression of glycolytic enzymes, particularly type II hexokinase (HKII) and aldolase B (ALDOB). This study examined the aberrant expression of HKII and ALDOB in 203 surgically resected HCCs. A dramatic down-regulation of(More)
PURPOSE Aurora-A/STK15/BTAK, a centrosome-associated serine/threonine kinase, has been shown to induce chromosomal instability, leading to aneuploidy and cell transformation. The purpose of this study was to investigate the expression and amplification of Aurora-A in hepatocellular carcinoma (HCC). EXPERIMENTAL DESIGN Aurora-A mRNA levels were measured in(More)
BACKGROUND/AIMS Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide and novel therapies are urgently needed. Recently, aberrant expression of Aurora kinases has been reported in various human cancers including HCC. We sought to investigate the potential of a potent and selective Aurora kinase inhibitor, VE-465, for targeted(More)
INTRODUCTION Mutation in the core promoter of the telomerase reverse transcriptase (TERT) gene was determined to be a frequent event in malignant melanoma and other cancers. However, the role of TERT promoter mutation in hepatocellular carcinomas (HCCs) remains largely unknown. METHODS Genomic DNA samples from the tumor tissue of 195 HCCs were analyzed(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)
