A DNA plasmid, designated pRS64, was detected in three isolates of anastomosis group 4 (AG-4) of Rhizoctonia solani Kühn by biophysical methods. The plasmid was a linear double-stranded DNA with a molecular weight of 1.68 +/- 0.06 X 10(6) or 2617 +/- 87 bp. Weakly pathogenic isolates of R. solani, 1668 RI-1, 1271 RI-64 and 1272 RI-1, which showed abnormally(More)
Unique DNA sequences homologous to the linear DNA plasmid pRS64 were investigated in chromosomal DNAs of isolates belonging to anastomosis group 4 (AG-4) of the plant pathogenic fungus Rhizoctonia solani. Chromosome-sized DNAs of isolates RI-64 and 1271 of AG-4 were separated into six bands by orthogonal-field-alternation gel electrophoresis and hybridized(More)
BACKGROUND Cancer stem cells (CSCs) are considered a pivotal target for the eradication of hepatocellular carcinoma (HCC). Recently, we reported that the CSC markers epithelial cell adhesion molecule (EpCAM) and CD90 are expressed independently in primary HCCs and cell lines, and CD90+ cells share features of metastatic vascular endothelial cells and(More)
BACKGROUND TSU-68 is a multikinase inhibitor that targets platelet-derived growth factor receptors (PDGFRs). In the present study, we evaluated the effect of TSU-68 on the tumor-microenvironment interaction in hepatocellular carcinoma (HCC). MATERIALS AND METHODS HCC and fibroblast cell lines (HuH7, Hep3B, HuH1 and WI-38) were used to evaluate their(More)
BACKGROUND/AIM Anthracimycin, a secondary metabolite of Streptomyces, has been shown to inhibit the invasion of certain cancer cell lines. MATERIALS AND METHODS In this study we evaluated the effect of anthracimycin on cell growth and signaling pathways in hepatocellular carcinoma (HCC). RESULTS Anthracimycin suppressed cell proliferation and motility(More)
