Green tea polyphenol (GTP) is one of the most promising chemopreventive agent for cancer; it can inhibit cancer cell proliferation and induce apoptosis through p53-dependent cell signaling pathways. Unfortunately, many tumor cells lack the functional p53, and little is known about the effect of GTP on the p53-deficient/mutant cancer cells. To understand the(More)
The aim of the present study was to determine the effects of 12-O-tetradecanoylphorbol-13-acetate (TPA) and diethyldithiocarbamate (DDTC) alone or in combination on human pancreatic cancer cells cultured in vitro and grown as xenograft tumors in nude mice. Pancreatic cancer cells were treated with either DDTC or TPA alone, or in combination and the number(More)
Developing a recombinant vector for noninvasively delivering biological macromolecules into the brain is important. This study constructed and purified a protein complex based on the cholera toxin (CT) molecular structure. Enhanced green fluorescent protein (EGFP)-modified A2 subunits of CT (CTA2) were used as tracer molecules for introduction of(More)
Trehalose, an important disaccharide in fungal spores, plays important role in protects against many environmental stresses, such as heat and salt. In this study, a gene (PiTPS) encoded trehalose-6-phosphate synthase was isolated from Phellinus igniarius (L.: Fr.) Quél, a basidiomycete fungus belonging to the family Polyporaceae. It contains many bioactive(More)
