PURPOSE We have previously identified a CD2 mediated, interleukin-12 dependent signaling pathway that inhibits activation induced cell death in mitogen stimulated human gammadelta-T cells, permitting the large-scale expansion of these cells. Herein we report the innate antitumor activity of expanded human Vgamma9Vdelta2+ gammadelta-T cells against human(More)
To determine, for various species, the pharmacological and biochemical properties of epothilone D (EpoD) that are relevant in establishing an appropriate animal model for further evaluation of this promising antitumor agent. A method involving high-performance liquid chromatography (HPLC) was developed and used to assess the stability and protein binding of(More)
The role of oxidative stress in alcoholic liver disease and cytokeratin aggresome formation is the focus of this in vitro study. HepG2 cells transduced to over express CYP2E1 (E47) and control HepG2 cells (C34) were first treated with arachidonic acid, then Fe-NAT, and finally with ethanol. In the E47 ethanol-treated cells, CYP2E1 was induced and a higher(More)
Excessive bone destruction is a major cause of morbidity in myeloma patients. However, the biological mechanisms involved in the pathogenesis of myeloma-induced bone disease are not fully understood. Heparanase, an enzyme that cleaves the heparan sulfate chains of proteoglycans, is upregulated in a variety of human tumors, including multiple myeloma. We(More)
Chronic ethanol ingestion leads to inhibition of proteasomal activity. As a consequence, proteins accumulate in liver cells. Cytokeratin accumulation as seen in alcoholic hepatitis could lead to the formation of Mallory bodies. In order to study the phenomenon of cytokeratin accumulation in liver cells, rats were fed ethanol or dextrose for 1 month and some(More)
Considerable change in the romantic and sexual behaviors of Asian young people may be occurring as traditionally Confucian societies modernize and increase outside contacts. This study explores the dimensions and context of this change in three sites at different stages in the process of modernization: Hanoi (early), Shanghai (intermediate), and Taipei(More)
The livers of mice fed diethyl 1,4-dihydro-2,4,6,-trimethyl-3,5-pyridinedicarboxylate (DDC) for 10 weeks formed Mallory bodies (MBs) in clusters of hepatocytes. Mice withdrawn from DDC for 9 months developed liver tumors. In the present study, the phenotype of the hepatocytes that formed MBs and tumors was characterized. Immunoperoxidase and(More)
Soil is an important epicenter of biodiversity. Human activity has threatened such biodiversity through vegetation shift. As the major type of microbes, bacteria have played key roles in material cycling. Since simple morphological characters and the failure of the major portion of bacteria in surviving artificial cultivation have hindered bacterial(More)
Hepatocyte growth factor (HGF) is a heparin-binding cytokine that enhances growth, motility, and angiogenesis of many tumor types, including multiple myeloma where it is often highly expressed. However, little is known regarding what controls HGF level and activity in these tumors. Evaluation of bone marrow biopsies from myeloma patients revealed a strong(More)
