PURPOSE This study aimed to identify a novel biomarker or a target of treatment for colorectal cancer (CRC). EXPERIMENTAL DESIGN The expression profiles of cancer cells in 104 patients with CRC were examined using laser microdissection and oligonucleotide microarray analysis. Overexpression in CRC cells, especially in patients with distant metastases, was(More)
BACKGROUND Gastric cancer is the second most frequent cause of death from cancer in the world, diffuse-type gastric cancer (DGC) exhibiting a poor prognosis. Germline mutations of CDH1, encoding E-cadherin, have been reported in hereditary DGC, and genetic and/or epigenetic alterations of CDH1 are frequently detected in sporadic DGC. Genetic alterations of(More)
Distant metastasis is the major cause of death in colorectal cancer (CRC) patients. To identify genes influencing the prognosis of patients with CRC, we compared gene expression in primary tumors with and without distant metastasis using an oligonucleotide microarray. We also examined the expression of the candidate gene in 100 CRC patients by quantitative(More)
We identified a novel prognostic biomarker for the distant metastasis of colorectal cancer (CRC) using comprehensive combined copy number and gene expression analyses. Expression of mRNA in CRC tissue was profiled in 115 patients using an Affymetrix Gene Chip, and copy number profiles were generated for 122 patients using an Affymetrix 250K Sty array. Genes(More)
BACKGROUND Identification of causative genes in mendelian forms of Parkinson's disease is valuable for understanding the cause of the disease. We did genetic studies in a Japanese family with autosomal dominant Parkinson's disease to identify novel causative genes. METHODS We did a genome-wide linkage analysis on eight affected and five unaffected(More)
In cancer metastasis, various environmental stressors attack the disseminating cells. The successful colonization of cancer cells in secondary sites therefore requires the ability of the cells to avoid the consequences of such exposure to the stressors. Here we show that orthotopic transplantation of a CD44 variant isoform-expressing (CD44v(+))(More)
Pegylated-interferon-alpha 2b (PEG-IFN) plus ribavirin (RBV) therapy is currently the de-facto standard treatment for hepatitis C virus (HCV) infection. The aims of this study were to analyze the clinical and virological factors associated with a higher rate of response in patients with HCV genotype 1b infection treated with combination therapy. We(More)
To identify key genes involved in the complex multistep process of hepatotumorigenesis, we reduced multivariate clinicopathological variables by using the Long-Evans Cinnamon rat, a model with naturally occurring and oxidative stress-induced hepatotumorigenesis. Gene expression patterns were analyzed serially by profiling liver tissues from rats of a naive(More)
BACKGROUND Patterns of cancer recurrence hold the key to prognosis after curative resection. This retrospective study aimed to identify a predictor and therapeutic candidate for aggressive recurrence of hepatocellular carcinoma (HCC). METHODS Primary HCC tissues from 107 patients who had curative resection were analysed. Genome-wide gene expression(More)
Background:Diffuse-type gastric cancer (DGC) exhibits rapid disease progression and a poor prognosis. There are no effective serum biomarkers for early detection of DGC. We have established an E-cadherin/p53 double conditional knockout (DCKO) mouse line that recapitulates human DGC morphologically and molecularly. In this study we tried to identify(More)
