The RNA 3 of rice stripe virus (RSV) isolate T was cloned and its nucleotide sequence was determined. The complete primary structure was found to consist of 2504 nucleotides. One putative open reading frame (ORF), between nucleotides 2412 and 1444 in the 5'-proximal region of the virus complementary-sense RNA, encoded a 322 amino acid protein with an Mr of(More)
The use of recombinant adenovirus (Ad) vectors containing genetically modified capsid proteins is an attractive strategy for achieving targeted gene transfer. The HI loop of the fiber knob is a promising candidate location for the incorporation of foreign ligands for achieving this goal. However, the method of constructing an Ad vector containing a foreign(More)
The establishment of self-renewing hepatoblast-like cells (HBCs) from human pluripotent stem cells (PSCs) would realize a stable supply of hepatocyte-like cells for medical applications. However, the functional characterization of human PSC-derived HBCs was not enough. To purify and expand human PSC-derived HBCs, human PSC-derived HBCs were cultured on(More)
Adipose tissues contain populations of pluripotent mesenchymal stem cells that also secrete various cytokines and growth factors to support repair of damaged tissues. In this study, we examined the role of oxidative stress on human adipose-derived multilineage progenitor cells (hADMPCs) in neurite outgrowth in cells of the rat pheochromocytoma cell line(More)
A methanol extract of the flower buds of Chimonanthus praecox (L.) Link (Calycanthaceae) demonstrated inhibitory effects on melanogenesis in theophylline-stimulated murine B16 melanoma 4A5 cells. From the extract, five dimeric pyrrolidinoindoline alkaloids and four sesquiterpenes were isolated, together with 16 known compounds. Among them, (−)-chimonanthine(More)
Human embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) have the potential to differentiate into all cell lineages, including hepatocytes, in vitro. Induced hepatocytes have a wide range of potential application in biomedical research, drug discovery, and the treatment of liver disease. However, the existing protocols for hepatic(More)
A novel sugar ester poacynose (1) was isolated from the flowers of Poacynum hendersonii together with 31 known compounds. The structure of 1 was established mainly on the basis of 1D and 2D NMR spectral data. Among the isolates, several constituents, such as kaempferol 3-O-sophoroside (5), picein (16), and 4-hydroxybenzoic acid 4-O-β-d-glucopyranoside (17)(More)
Recombinant adenovirus (Ad) vectors have been used extensively to deliver foreign genes to a variety of cell types in vitro and in vivo (17,19). One problem associated with the use of Ad vectors has been the difficulty of constructing a vector. We recently developed an efficient method for constructing an E1 (E1/E3 or E1/E3/E4)-deleted Ad vector by means of(More)
A methanol extract of everlasting flowers of Helichrysum arenarium L. Moench (Asteraceae) was found to inhibit the increase in blood glucose elevation in sucrose-loaded mice at 500 mg/kg p.o. The methanol extract also inhibited the enzymatic activity against dipeptidyl peptidase-IV (DPP-IV, IC50 = 41.2 μg/ml), but did not show intestinal α-glucosidase(More)
The establishment of methods for directive differentiation from human embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) is important for regenerative medicine. Although Sry-related HMG box 17 (SOX17) overexpression in ESCs leads to differentiation of either extraembryonic or definitive endoderm cells, respectively, the mechanism of(More)
