Effects of osmotic stress on Na/K-ATPase, caspase 3/7 activity, and the expression profiling of sirt1, hsf1, and hsp70 in the roughskin sculpin (Trachidermus fasciatus).

Osmoregulation mechanism underlying acclimation of migratory fish to different salinities has been a classical research topic for decades. In this study, the roughskin sculpin (Trachidermus fasciatus) were subjected to two different acute osmotic treatments (one extreme acute and one acute treatment, i.e.
