The substrate specificity of hormone-sensitive lipase from adipose tissue of the Antarctic fish Trematomus newnesi.
Antarctic fishes of the suborder Notothenioidei characteristically possess large stores of neutral lipids that have been shown to be important both in conferring buoyant lift and as a caloric resource for energy metabolism. Previous work has established that the aerobic energy metabolism of Antarctic fish is fueled predominantly by the catabolism of fatty acids, with the catabolic machinery dis...
متن کاملHeat-shock protein expression is absent in the antarctic fish Trematomus bernacchii (family Nototheniidae).
The heat-shock response, the enhanced expression of one or more classes of molecular chaperones termed heat-shock proteins (hsps) in response to stress induced by high temperatures, is commonly viewed as a 'universal' characteristic of organisms. We examined the occurrence of the heat-shock response in a highly cold-adapted, stenothermal Antarctic teleost fish, Trematomus bernacchii, to determi...
متن کاملComposition of cultivable enteric bacteria from the intestine of Antarctic fish (family Nototheniidae)
In this study, the intestinal bacteria of wild Antarctic fish (family Nototheniidae) were examined using traditional culture-based techniques. Bacterial flora of the gut contents of four marine fish species (Notothenia coriiceps, Trematomus bernacchii, Trematomus hansoni, and Trematomus newnesi) was investigated to describe the allochthonous bacteria inhabiting these Nototheniidae fish. A set o...
متن کاملNervous and sensory system correlates of an epibenthic evolutionary radiation in antarctic notothenioid fishes, genus Trematomus (Perciformes; Nototheniidae).
The perciform suborder Notothenioidei consists of 120 species, with 94 confined to the Antarctic Region of the Southern Ocean. On the Antarctic shelf, this phyletic radiation has been accompanied by a substantial morphological and ecological diversification towards a pelagic existence. For example, the primarily benthic genus Trematomus contains an epibenthic radiation that includes T. loennber...
متن کاملRegulation of heat shock genes in isolated hepatocytes from an Antarctic fish, Trematomus bernacchii.
The Antarctic fishes, isolated over evolutionary history in the sub-zero waters of the Southern Ocean, are an ideal group for studying the processes of cold adaptation. One species of Antarctic notothenioid fish, Trematomus bernacchii, has lost the ability to induce heat shock proteins (Hsps) in response to exposure to acute thermal stress or to the toxic heavy metal cadmium, an important part ...
