Downregulation of the miR-143/145 microRNA (miRNA) cluster has been repeatedly reported in colon cancer and other epithelial tumors. In addition, overexpression of these miRNAs inhibits tumorigenesis, leading to broad consensus that they function as cell-autonomous epithelial tumor suppressors. We generated mice with deletion of miR-143/145 to investigate(More)
Down-regulation of miR-26 family members has been implicated in the pathogenesis of multiple malignancies. In some settings, including glioma, however, miR-26-mediated repression of PTEN promotes tumorigenesis. To investigate the contexts in which the tumor suppressor versus oncogenic activity of miR-26 predominates in vivo, we generated miR-26a transgenic(More)
Cell adhesion molecules (CAMs) play an important role in cancer metastasis by facilitating attachment to vascular endothelia, invasion and spread into secondary tissue sites. We have shown that activated eosinophils (EosA) inhibited the growth of prostate cancer (Pca) cells in vitro. In the present study, we examined the ability of EosA 24 hr conditioned(More)
BACKGROUND Previous studies in our laboratory have shown that activated eosinophils and eosinophilic cell lines inhibit the in vitro growth of MCF-7 breast tumor cells. We have also shown that IL-4 and IL-5 partially inhibit MCF-7 growth in vitro. In this study MCF-7 multicellular tumor spheroids (MTS) were developed to study the effect of eosinophils and(More)
OBJECTIVES There is interest in improving the tumoricidal effects of preoperative radiotherapy for rectal carcinoma by studying new radiosensitizers. The safety and toxicity profile of these combination regimens needs rigorous clinical evaluation. The primary objective of this study was to evaluate the toxicity of combining bavituximab, an antibody that(More)
BACKGROUND Host Immune response to prostate cancer primarily involves the CTL and NK effector cells. Recent immunotherapeutic strategies incorporating cytokine genes into the tumor cell and/or dendritic cells have had encouraging results. In this study, we describe the inhibitory activity of a third potential effector cell, the eosinophil, against DU 145(More)
Significant damage of transportation infrastructure systems usually occurs during a major earthquake event. The impacts of bridge damage include not only short-term costs of structural repair, but also long-term economic consequences. In addition to initial replacement or repair costs of damage to the transportation structures, large earthquakes increase(More)
