Figure 7: Expression of PLB, phosphorylated PLB at Ser16 (phospho Ser16-PLB) and at Thr17 (phospho Thr17-PLB) in the myocardium after the pacing and ISO treatment. (a) The representative Western blots of PLB, phosphorylated PLB at Ser16 and Thr17. (b) Expression of total PLB measured by pentametric plus monomeric forms. (c) Expression of phospho Ser16-PLB. (d), expression of phospho Thr17-PLB. Data are mean ± SEM, hearts in each group. * or ** versus baseline.
