Expression of ER stress markers in myocardium from WT and APP/PS1 mice.

<p>A: Representative gel blots depicting the ER stress markers IRE1α, phosphorylated IRE1α, BiP and calregulin (calreticulin) using specific antibodies. α-tubulin was used as an loading control; B: phosphorylated IRE 1α/IRE 1α ratio; C: calregulin; and D: Bip. Mean±SEM, n = 4.
