Regulation of Glucose Uptake and Transporter Expression in the North Pacific Spiny Dogfish (Squalus suckleyi)
… investigated in the North Pacific spiny dogfish (Squalus suckleyi). In particular, the presence of a putative GLUT4 transporter, which was previously thought to have been lost in these fish, was established and its mRNA levels were shown to be upregulated by feeding (intestine, liver, and muscle), …
