Therapeutic Potential of Ex Vivo Expanded γδ T Cells against Osteosarcoma Cells.

Immunotherapy is an attractive therapeutic strategy for the treatment of osteosarcoma (OS). The unique features of γδ T cells have made them popular for cancer immunotherapy. Here, we expanded γδ T cells using human peripheral blood mononuclear cells (PBMCs) and investigated their therapeutic potential against OS cells.

Development of a Bioluminescent Human Osteosarcoma Model in Humanized NSG Mice: A Pilot Study.

Background/aim: Osteosarcoma is the most common type of bone cancer, but current therapeutic interventions remain largely insufficient. The development of new treatment strategies is needed, and moreover, optimal rodent models are necessary for testing the efficacy of new treatment modalities of osteosarcoma. Humanized mice carry human hematopoietic and immune systems, and are considered an ideal tool to study human diseases including cancer immunology.

Kinetic study for the optimization of ginsenoside Rg3 production by heat treatment of ginsenoside Rb1.

Background: Ginsenoside Rg3 is a promising anticancer agent. It is usually produced by heat treatment of ginseng, in which ginsenoside Rb1 is the major ginsenoside. A kinetic study was conducted to optimize ginsenoside Rg3 production by the heat treatment of ginsenoside Rb1.

Effects of Aster scaber Seed Oil Containing trans-Δ3 Fatty Acids on Lipid Profiles of Hamsters and Rats.

The effects of Aster scaber seed oil (ASO) on lipid profiles were studied in rats and hamsters. ASO contained considerable amounts of Δ3t-16:1 (11.4%), Δ3t, 9c-18:2 (4.

Developmental expression of Pitx2c in Xenopus trigeminal and profundal placodes.

Cranial placodes are thickenings of the embryonic head ectoderm that contribute to the paired sense organs and to the cephalic peripheral nervous system. Here we report the spatiotemporal expression pattern of transcription factor Pitx2c during Xenopus laevis cranial placode formation, focusing more specifically on key stages of trigeminal and profundal placode development. We also compare its expression to five genes that have been associated with development of these sensory placodes, namely Foxi1c, Islet1, NeuroD, Pax3, and Six1.

Effect of Korean red ginseng extract on liver damage induced by short-term and long-term ethanol treatment in rats.

Korean red ginseng (KRG) is prepared by the process of steaming the roots of Panax ginseng. In this study, the feeding effects of KRG-water extract (KRGE) on ethanol-induced liver damage were elucidated by measuring serum biomarkers in rats. Serum γ-glutamyltranspeptidase (γ-GT) activity and the concentration of malondialdehyde (MDA) were significantly increased by short-term and long-term ethanol treatment in rats, whereas the activities of serum glutamate pyruvate transaminase (GPT) and glutamate oxaloacetate transaminase (GOT) did not respond.

Hypolipidaemic effects of dietary whole soybean curd (jeondubu) in rats.

Background: The characteristic of whole soybean curd is that it includes the soybean residue that is discarded as waste in the manufacture of usual soybean curd (known as tofu). In this study the effect of dietary whole soybean curd on lipid profiles in rats was compared with that of usual soybean curd. Rats were fed for 4 weeks with diets differing only in the source of protein, namely casein, whole soybean curd or usual soybean curd.

Enhancing phage display of antibody fragments using gIII-amber suppression.

The effect of utilizing Ex12 helper phage, a mutant M13K07 helper having two amber codons at the gIII (gIII-amber), in combination with Escherichia coli host strains belonging to the supE genotype on improving the phage display of antibody fragments was investigated. Because of an inefficient read-through of the UAG codons, Ex12 helper phage produced approximately 10% of the intracellular wt pIII in the supE host cells compared to M13K07. The phage progenies rescued from the supE XL-1 Blue MRF' strain carrying the recombinant phagemid, pCMTG-SP112, by Ex12 helper phage displayed both antibody-DeltapIII fusion and wt pIII at a ratio of 1:1.
