In the present study, we compared mesenchymal stem cells (MSCs) derived from 4 different sources, human bone marrow (BM), adipose tissue (AT), umbilical cord Wharton's Jelly (WJ) and the placenta (PL), in order to determine which population of MSCs displayed the most prominent immunosuppressive effects on phytohemagglutinin-induced T cell proliferation, and(More)
Rosmarinic acid (RA) is a naturally occurring polyphenolic compound. It is found in several herbs in the Lamiaceae family, such as Perilla frutescens. RA has been reported to exert anti-oxidative effects on rat erythrocyte, liver, and kidney cells. However, little is known about the effects of RA on dopaminergic cells. In the present study, we investigated(More)
The expression of virulence determinants in Staphylococcus aureus is controlled by global regulatory loci (e.g., sarA and agr). One of these determinants, protein A (spa), is activated by sarS, which encodes a 250-residue DNA-binding protein. Genetic analysis indicated that the agr locus likely mediates spa repression by suppressing the transcription of(More)
In a previous study, we found that the global genome organizer Special AT-rich binding protein 1 (SATB1) is highly expressed in mesenchymal-derived human osteosarcoma U2OS cells and that the knock-down of SATB1 results in the inhibition of cell proliferation. The present study was aimed at investigating the effect of silencing SATB1 on cell migration,(More)
It has been shown that over-expression of Special AT-rich binding protein 1 (SATB1) in breast cancer predicts a poor prognosis. This study was aimed at investigating the effects of silencing SATB1 on mesenchymal derived human osteosarcoma U2OS cells and the underlying mechanisms. The expressions of SATB1 and the related genes in the cells were detected by(More)
In order to investigate the effects of flagellin secreted by bacteria associated with pine wood nematode (Bursaphelenchus xylophilus) on pine cells, suspension cells of Pinus thunbergii were treated with flagellin of Pseudomonas fluorescens GcM5-1A, and some physiological indices were determined. Superoxide anions radical (·O2 −) in treated suspension cells(More)
Intestinal alkaline phosphatase (IAP) is one of the major sources of alkaline phosphatase in circulation. It is secreted into the intestinal lumen, serum, and lymph. After the ingestion of lipid, lymphatic alkaline phosphatase secretion increases significantly. We have found that the nonabsorbable fat olestra is unable to stimulate lymphatic alkaline(More)
It is known that several bacteria are adherent to the surface coat of pine wood nematode (Bursaphelenchus xylophilus), but their function and role in the pathogenesis of pine wilt disease remains debatable. The Pseudomonas fluorescens GcM5-1A is a bacterium isolated from the surface coat of pine wood nematodes. In previous studies, GcM5-1A was evident in(More)
Arsenic trioxide (ATO) has been successfully used to treat leukemia and some solid malignant tumors. Our previous study regarding the effects of ATO on mesenchymal-derived human osteosarcoma MG63 cells showed that heme oxygenase-1 (HO-1) was strongly induced upon treatment with ATO. The present study sought to investigate the effect of silencing HO-1 on the(More)
Pine wilt disease (PWD), a destructive disease for pine trees, is caused by the pine wood nematode (PWN), Bursaphelenchus xylophilus and additional bacteria. In this study, extracts of Zostera marina showed a high nematicidal activity against PWN and some of the bacteria that it carries. Light yellow crystals were obtained from extracts of Z. marina through(More)
