Stems of genus Dendrobium (Orchidaceae) have been traditionally used as an herbal medicine (Dendrobii Herba) in Eastern Asia. Although demand for Dendrobium is increasing rapidly, wild resources are decreasing due to over-collection. This study aimed to identify plant sources of Dendrobii Herba on the market based on sequences of the internal transcribed(More)
Several structurally unrelated scaffolds of the Rho kinase inhibitor were designed using pharmacophore information obtained from the results of a high-throughput screening and structural information from a homology model of Rho kinase. A docking simulation using the ligand-binding pocket of the Rho kinase model helped to comprehensively understand and to(More)
ADP-ribosylation factor 1 (Arf1) plays a major role in mediating vesicular transport. Brefeldin A (BFA), a known inhibitor of the Arf1-guanine nucleotide exchange factor (GEF) interaction, is highly cytotoxic. Therefore, interaction of Arf1 with ArfGEF is an attractive target for cancer treatment. However, BFA and its derivatives have not progressed beyond(More)
We analyzed the inheritance of DNA methylation in the first filial generation(F1) hybrid of Oryza sativa L. ("Nipponbare"x"Kasalath") by restriction landmark genome scanning (RLGS). Most parental RLGS spots were found in the F1, but eight spots (4%) showed abnormal inheritance: seven of the eight spots were missing in the F1, and one was newly detected in(More)
A promising strategy as a cancer therapeutic is tumor-targeted gene delivery. The AG73 peptide derived from the laminin alpha1 chain is a ligand for syndecans, and syndecan-2 is highly expressed in some cancer cells. In this study, AG73-PEG liposomes were developed for selective gene delivery to syndecan-2 overexpressing cancer cells. AG73-PEG liposomes(More)
BACKGROUND Multiple system atrophy (MSA) is a sporadic disease. Its pathogenesis may involve multiple genetic and nongenetic factors, but its etiology remains largely unknown. We hypothesized that the genome of a patient with MSA would demonstrate copy number variations (CNVs) in the genes or genomic regions of interest. To identify genomic alterations(More)
Endothelial progenitor cells (EPCs) are known to repair vascular injuries. Recent studies suggest that Saiko-ka-ryukotsu-borei-To (SKRBT), a traditional herbal medicine that has been used to treat stress-related neuropsychiatric disorders, has protective effects on cardiovascular diseases such as hypertension and arteriosclerosis. Spontaneously hypertensive(More)
Targeted gene delivery to cancer cells is considered as a promising strategy for cancer therapy. Since, several targeting ligands have been studied for cancer gene therapy, such as transferrin, folate, anisamide, RGD-peptide, and antibodies. We have focused on AG73 peptide, which is derived from the globular domain of the laminin α1 chain. AG73 peptide is(More)
We developed laminin-derived AG73 peptide labeled liposomes for cancer specific gene therapy. AG73 peptide is well known as a ligand for syndecan-2 which is highly expressed in various cancer cells. Liposomes labeled with AG73 showed high efficient transfection efficiency in syndecan-2 overexpressing cells, and found that AG73 could be a superior molecule(More)
