The hormonal stress response is adapted to deal with acute (short-term) stressors; however, chronic (long-term) stressors have negative effects on survival and fitness. Field and laboratory evidence suggest that voles respond behaviourally to predator odours. However, it is unknown whether voles mount an acute hormonal stress response to predator odour. We determined whether reproductively acti...

Prostate cancer is the most common nonskin cancer in American men, and androgen-deprivation therapy is the cornerstone of treatment for advanced prostate cancer. Unfortunately, the median duration of response to initial androgen deprivation is limited to 18–24 months. After failing primary therapy, many individuals respond to multiple secondary hormonal interventions, such as ketoconazole. A po...

The industrial use of elicitors as alternative tools for disease control needs the identification of abundant sources of them. We report on an elicitor obtained from the green algae Ulva spp. A fraction containing most exclusively the sulfated polysaccharide known as ulvan-induced expression of a GUS gene placed under the control of a lipoxygenase gene promoter. Gene expression profiling was pe...
