The mechanisms by which tumors develop resistance to angiogenesis inhibitors, and the relative contributions of tumor cells and stroma to resistance, are not completely understood. We developed three human lung adenocarcinoma murine models of resistance to the VEGF inhibitor bevacizumab and, using s...

The homeodomain transcription factor, Pdx-1, has important roles in pancreatic development and M-NM-2-cell function and survival. In the present study, we demonstrate that adenovirus-mediated overexpression of Pdx-1 in rat or human islets also stimulates cell replication. Moreover, co-overexpression...

Mouse embryonic stem cells were maintained in minimal and chemically-defined culture conditions supporting naive pluripotency. Inhibitors of the Gsk3 (CHIR99021) and Mek/Erk (PD0325901) pathways were withdrawn, cultures maintained for 24 hours, and subsequently sorted by flow cytometry based on fluo...

Background: Current evidence indicates that even low-level lead (Pb) exposure can have detrimental effects, especially in children. We tested the hypothesis that Pb exposure alters gene expression patterns in peripheral blood cells and that these changes reflect dose-specific alterations in the acti...

Bovine rotavirus (BRV) and bovine coronavirus (BCV) infect intestinal villous epithelium in young cattle. A surgical model was adapted for neonatal calves in which a region of the jejunum was isolated from the digestive tract but lymph drainage, enervation and blood flow were maintained. Replicate s...

Oligonucleotide DNA microarrays were used as a platform to compare C. jejuni isolates from feedlot cattle and human clinical cases from Alberta. Comparative genomic hybridization (CGH) analysis was performed on 87 isolates (46 bovine, 41 human) obtained within the same geographical regions and time ...
