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 ...

Mitochondrial biogenesis requires an intricate transcriptional coordination between the nuclear and mitochondrial genomes to establish the structural and functional components of the organelle. This coordination is paramount ...

Pacific salmon (Oncorhynchus spp.) production strongly influences the ecosystems, cultures and economies of the Northeast Pacific. Historical variability in population sizes is complex, reflecting natural and human drivers. ...

Migratory birds spend most of the year on the over-wintering grounds or traveling between breeding and wintering areas, but research has focused on the relatively short breeding period. As a consequence, we have only a ...

Allatostatins (ASTs) are neuropeptides that inhibit the biosynthesis and release of juvenile hormone from the corpora allata (CA) of various insects including the cockroach Diploptera punctata. We hypothesized that a similar ...

The neuroendocrine basis of paternal behaviour is hypothesised to be homologous to that of maternal behaviour, with the expression of paternal behaviour resulting from the activation of estrogen-sensitive pathways in the ...

There has been a recent paradigm shift in the study of animal communication from examining interactions as dyads to considering interactions as occurring in a communication network. The dawn chorus of songbirds, a striking ...

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 ...

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 ...
