Beta3-adrenergic receptors--studies on rainbow trout reveal ancient evolutionary origins and functions distinct from the thermogenic response.
FOR MOST PHYSIOLOGISTS it is clear that the major function for 3-adrenergic receptors is to mediate metabolic and thermogenic responses in adipose tissue (12). Thus one would expect their distribution to be restricted to homeothermic animals. However, in this issue of the American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, Nickerson et al. (5) report the presence ...
متن کاملSerotonin Coordinates Responses to Social Stress—What We Can Learn from Fish
Social interaction is stressful and subordinate individuals are often subjected to chronic stress, which greatly affects both their behavior and physiology. In teleost fish the social position of an individual may have long-term effects, such as effects on migration, age of sexual maturation or even sex. The brain serotonergic system plays a key role in coordinating autonomic, behavioral and ne...
متن کاملTeleocortin: A Novel Member of the CRH Family in Teleost Fish.
The CRH family of neuropeptides, including CRH and urocortins, plays pivotal roles in the regulation of physiological and behavioral stress responses in vertebrates. In this study, we identified a previously undescribed member of the CRH family of peptides in a teleost fish species (medaka; Oryzias latipes) and named this peptide teleocortin (Tcn). Medaka Tcn is a 41-amino acid polypeptide deri...
متن کاملBehavioral indicators of stress-coping style in rainbow trout: Do males and females react differently to novelty?
It is becoming increasingly clear that individual differences in the behavioral response to stressful situations are associated with distinct physiological profiles, and stress coping characteristics are of fundamental importance to fitness and life history. Teleost fishes display considerable variation in reproductive strategy, but sex differences in stress-coping style have not been described...
متن کاملIron acquisition by teleost fish.
Iron is a vital micronutrient for teleost fish, being an integral component of proteins involved in cellular respiration and oxygen transfer. However, in excess iron is toxic, and fish need to balance uptake to prevent deficiency vs. potential toxicity. This review assesses the current physiological and molecular knowledge of the mechanisms of iron acquisition in the teleost fish. It focuses on...
