View SamplesSurgical samples have long been used as important subjects for cancer research. In accordance with an increase of neoadjuvant therapy, biopsy samples have recently become imperative for cancer transcriptome. On the other hand, both biopsy and surgical samples are available for expression profiling for predicting clinical outcome by adjuvant therapy; however, it is still unclear whether surgical sample expression profiles are useful for the prediction by the use of biopsy samples because little has been done about comparative gene expression profiling between the two kinds of samples.

View SamplesThe gene mucAB has an error-prone activity in bacteria. We introduced mucAB into mouse 3T3 cells with an expression vector and found drastic increase of spontaneous transformation, accompanied by increase of expression of eight oncogenes, i. e., Gpnmb, Foxml, Maff, Myc, Aurka, Aukb, Fosl1, and Anxa8 and decrease of expression in two oncogenes, i. e., Lrig1 and RhoX in order of the magnitude of change, as compared with those in non-treated 3T3 cells.

View SamplesAlthough peritoneal dissemination is a major obstacle in treating diffuse-type GC patients, the mechanism is still unclear. To address this phenomenon from the viewpoint of molecular biology, we established a highly peritoneal-metastatic cell line, 60As6, from a diffuse-type GC derived cell line, HSC-60, through a six-times iterative in vivo selection consisting of an orthotopic inoculation of the tumor cells and the isolation of highly-metastatic ones from the ascites of immunodeficient mice. To assess the biological differences between HSC-60 and 60As6 cells, we compared gene expression profiles for both cell lines by microarray analysis. Down-regulation of three gastric pit cell differentiation markers and some cytokeratins were found in 60As6. By contrast, several stem cell markers were up-regulated in this cell line. The expression profile suggests that 60As6 has a strong mensencymal phenotype, which is a characteristic of epithelial cell-derived CSCs.

View SamplesSHH signaling pathway is activated in many type of cancers. However, the role of its activation in particular type of cancer was poorly understood. The GLI family transcription factor GLI1 is the effector of Shh pathway activation and functions as oncogene. Our goal of research is to identify the GLI1 targets in desmoplastic medulloblastomas.

View SamplesGastric cancers account for the fourth most frequent cancer death worldwide. Although many differential gene expression profiles are reported for gastric cancers, their variation at the post-transcriptional level has not been provided yet. In this study, we compared the gene expressions of normal stomach vs. stomach cancer in an exon-wise manner and compared alternatively spliced transcripts. The RNA from normal and cancer tissues of gastric cancer patients were subjected to Exon 1.0 ST microarrays.
