Because retrotransposons are the major component of plant genomes, analysis of the target site selection of retrotransposons is important for understanding the structure and evolution of plant genomes. Here, we examined the target site specificity of the rice retrotransposon Tos17, which can be activated by tissue culture. We have produced 47,196(More)
Plant growth and development are sustained by continuous cell division in the meristems, which is perturbed by various environmental stresses. For the maintenance of meristematic functions, it is essential that cell division be coordinated with cell differentiation. However, it is unknown how the proliferative activities of the meristems and the(More)
Hepatocellular carcinoma (HCC) is highly malignant and prone to multicentric occurrence. Differentiation between a true relapse of HCC and a second primary tumour appearing is of clinical importance. At this point, no convenient method is available to determine the origin of these HCCs. Tissue samples were obtained from 19 patients and analysed for the(More)
We investigated the biological activity of IL-4 to murine connective tissue-type mast cells (CTMC). When purified peritoneal mast cells, typical CTMC, were incubated with pokeweed mitogen-stimulated spleen cell-conditioned medium (PWM-SCM) in methylcellulose, about one-fifth of mast cells showed clonal growth. Recombinant IL-4 alone did not stimulate the(More)
BACKGROUND To identify genes associated with hepatocellular carcinoma (HCC) pathogenesis, we developed a triple combination array strategy comprising methylation, gene expression, and single nucleotide polymorphism (SNP) array analysis. METHODS Surgical specimens obtained from a 68-year-old female HCC patient were analyzed by triple combination array, and(More)
Alteration in transforming growth factor-beta signalling pathway is one of the main causes of pancreatic cancer. The human runt-related transcription factor 3 gene (RUNX3) is an important component of this pathway. RUNX3 locus 1p36 is commonly deleted in a variety of human cancers, including pancreatic cancer. Therefore, we examined genetic and epigenetic(More)
BACKGROUND To detect genes correlated with hepatocellular carcinoma (HCC), we developed a triple combination array consisting of methylation array, gene expression array and single nucleotide polymorphism (SNP) array analysis. METHODS A surgical specimen obtained from a 68-year-old female HCC patient was analyzed by triple combination array, which(More)
Hepatocellular carcinoma (HCC) is one of the major causes of cancer-related death especially among Asian and African populations. It is urgent that we identify carcinogenesis-related genes to establish an innovative treatment strategy for this disease. Triple-combination array analysis was performed using one pair each of HCC and noncancerous liver samples(More)
BACKGROUND A single nucleotide polymorphism (SNP) in the epidermal growth factor (EGF) gene (rs4444903) has been associated with increased risk of cancer, including hepatocellular carcinoma (HCC). The aim of this study was to examine the relationship between the EGF SNP genotype and the development and prognosis of HCC, in a Japanese population. METHODS(More)
Chromatin states are inseparably associated with regulation of genes. In yeast and animals, chromatin states also correlate with the configuration and spatial localization pattern of chromosomal domains in the nucleus. In plants, however, the dynamics of such domains associated with gene regulation is poorly understood except for heterochromatic domains. We(More)
