Endocrine responses to unpredictable environmental events: stress or anti-stress hormones?
In addition to seasonal changes in morphology, physiology and behavior that occur in predictable annual cycles, there are facultative responses to unpredictable events known as labile (i.e., short-lived) perturbation factors (LPFs). These rapid behavioral and physiological changes have been termed the "emergency" life history stage (ELHS) and serve to enhance life-time fitness. Glucocorticoster...
متن کاملAnti-stress hormones
B-ring hydroxylation is a major metabolic pathway for cholesterols and some steroids. In liver, 7αhydroxylation of cholesterols, mediated by CYP7A and CYP39A1, is the rate limiting step of bile acid synthesis and metabolic elimination. In brain and other tissues, both sterols and some steroids including dehydroepiandrosterone (DHEA) are prominently 7α-hydroxylated by CYP7B. The function of extr...
متن کاملEpigenomics of Plant’s Responses to Environmental Stress
Genome-wide epigenetic changes in plants are being reported during the development and environmental stresses, which are often correlated with gene expression at the transcriptional level. Sum total of the biochemical changes in nuclear DNA, post-translational modifications in histone proteins and variations in the biogenesis of non-coding RNAs in a cell is known as epigenome. These changes are...
متن کاملAn Efficient Chronic Unpredictable Stress Protocol to Induce Stress-Related Responses in C57BL/6 Mice
Exposure to chronic stress can have broad effects on health ranging from increased predisposition for neuropsychiatric disorders to deregulation of immune responses. The chronic unpredictable stress (CUS) protocol has been widely used to study the impact of stress exposure in several animal models and consists in the random, intermittent, and unpredictable exposure to a variety of stressors dur...
متن کاملStress in Atlantic salmon: response to unpredictable chronic stress.
Combinations of stressors occur regularly throughout an animal's life, especially in agriculture and aquaculture settings. If an animal fails to acclimate to these stressors, stress becomes chronic, and a condition of allostatic overload arises with negative results for animal welfare. In the current study, we describe effects of exposing Atlantic salmon parr to an unpredictable chronic stresso...
