Activity of Na+/K+-ATPase and the content of phospholipids in the blue mussel Mytilus edulis L. during environmental temperature changes

Abstract

Changes in the activity of Na⁺/K⁺-ATPase and content of membrane lipids (phospholipids) in the gills and hepatopancreas of the blue mussel Mytilus edulis L. have been studied during a sharp temperature increase under aquarian managed conditions. The most pronounced changes were recorded in mollusk gills. A correlation of changes in the activity of membrane-bound Na⁺/K⁺-ATPase and phospholipid content (mainly phosphatidylserine, phosphatidylinositol, phosphatidylethanolamine, and lysophosphatidylcholine) was revealed; this correlation evidences their mutual involvement in compensation for the temperature effect to help mussels adapt to sharp temperature changes.
