ErbB receptor protein expression in myocardium early and late after MI. A

<p>) Representative Western blot for ErbB2 and ErbB4 in early post-MI (5 weeks) vs late post-MI (12 weeks). <b>B</b>) Quantification of myocardial ErbB2 receptor expression after densitometric analyses. ErbB2 expression was normalized to α-tubulin expression for each of the groups. ErbB2 expression was increased early post MI compared to sham (p = 0.01) and late post MI (p = 0.03). <b>C</b>) Quantificationof myocardial ErbB4 receptor expression after densitometric analyses of blotted bands. Normalized ErbB4 expression to α-tubulin was similar in all groups.
