Several genes involved in the regulation of apoptosis can influence longevity. Although observations in several different systems imply that apoptosis and aging are closely linked, the relationship between the two remains ...

In multicellular organisms, apoptosis plays an important role in maintaining cellular homeostasis and removing damaged cells that present a threat to the integrity of the organism. Several lines of evidence suggest that ...

Cancer cells have the ability to survive when oxygen is limiting, and upregulate the pathway of fatty acid synthesis, owing in part to alterations in their metabolism. I compared the metabolic phenotypes of the prostate ...

Bythotrephes longimanus, a predatory exotic cladoceran, has spread rapidly to numerous lakes through the Laurentian Great Lakes region of Ontario and North America. Post-invaded lakes are known to have reduced zooplankton ...

Until recently it has been widely believed that significant anthropogenic influences on the environment began in Canada following the onset of European colonization. However, our paleolimnological data indicate that ...

Embryogenesis was observed through light and transmission electron microscopy to elucidate the role of the cytoskeleton in the cellularization of the coenocytic endosperm in Helianthus annuus. Microtubules were not seen ...

The acidification and metal contamination of freshwater resources are major environmental concerns in many areas, with Sudbury (Ontario, Canada) having been amongst the most severely impacted. Many scientific investigations ...

Our understanding of tree growth and development has increased substantially in the last few decades and is expected to increase much more as we fully exploit newly developed genomic tools. A major milestone in tree genomics ...

Paleoclimatic research in the Canadian Arctic has increased in recent decades; however, there is still much to learn about the nature and extent of past climate change in this vast, environmentally sensitive region. This ...

The peacock (Pavo cristatus) has long been considered the quintessential example of a sexually selected animal, and in the last two decades, peafowl have provided widely-cited evidence for female mate choice as well as the ...
