PURPOSE Abnormal spindle-like microcephaly associated (ASPM) plays an important role in neurogenesis and cell proliferation. This study is to elucidate its role in hepatocellular carcinoma (HCC), particularly early tumor recurrence (ETR) and prognosis. EXPERIMENTAL DESIGN We used reverse transcription-PCR assays to measure the ASPM mRNA levels in 247 HCC(More)
The expression of microRNA (miRNA) genes undergoes several maturation steps. Recent studies brought new insights into the maturation process, but also raised debates on the maturation mechanism. To understand the mechanism better, we downloaded small RNA sequence reads from NCBI SRA and quantified the expression profiles of miRNAs in normal and tumor liver(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)
Chromosome 4q exhibits high frequency of allelic loss in hepatocellular carcinoma (HCC). This study aimed to elucidate the interaction of the frequent aberrant mRNA expression of alpha-fetoprotein (AFP), osteopontin (OPN) and a novel short isoform of annexin A10 (ANXA10S) at 4q in the tumor progression among 294 patients who received surgical resection of(More)
BACKGROUND Intrahepatic metastasis via portal vein spread is an important feature and a crucial unfavorable prognostic factor of hepatocellular carcinoma (HCC). To identify the molecular factors for tumor progression, the authors used differential display (DD) to analyze aberrant gene expression in HCC. The goal of the current study was to elucidate the(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)
MicroRNAs are small non-coding RNA molecules that play important roles in the multistep process of colorectal carcinoma (CRC) development. The present study evaluated the relationship between miR-1-1 and miR-133a-2 expression and DNA methylation, and its putative biological role in CRC. The results indicated that DNA(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)
Annexins (ANXs) are a large group of calcium-binding proteins participating in diverse important biological processes. ANXA10 is the least expressed new member of unknown function. We showed that ANXA10 mRNA was expressed in adult liver and hepatocellular carcinoma (HCC), but not in multiple adult and fetal tissues, cholangiocarcinoma, and several other(More)
L2DTL is a human ortholog of Drosophila lethal (2) denticleless, l(2)dtl. This study is to elucidate its function and clinicopathological significance in hepatocellular carcinoma (HCC) progression. We used RT-PCR, immunostaining, Western blotting, and centrosome isolation to determine the L2DTL expression and protein localization, and RNAi to analyze its(More)
