Thermal sensitivity of liver cell metabolism of different Antarctic fish species

Temperature dependent cell respiration and energy expenditure for protein synthesis were determined in primary hepatocytes of different fish species of the South Atlantic: the circumpolar-distributed Antarctic eelpout Pachycara brachycephalum (sampling location: 62°19′S; 58°33′W) and, of two notothe...

Description
Summary:Temperature dependent cell respiration and energy expenditure for protein synthesis were determined in primary hepatocytes of different fish species of the South Atlantic: the circumpolar-distributed Antarctic eelpout Pachycara brachycephalum (sampling location: 62°19′S; 58°33′W) and, of two notothenioids the sub-Antarctic Lepidonotothen squamifrons (sampling location: 53°24′S; 42°40′W) and the high-Antarctic icefish Chionodraco hamatus (sampling location: 70°19′S; 10°22′W). We used intermittent-flow respirometry and closed system respirometry to analyse cellular response to acute warming.
