Figure 4From: Type 1 diabetes mellitus abrogates compensatory augmentation of myocardial neuregulin-1β/ErbB in response to myocardial infarction resulting in worsening heart failureMyocardial protein expression of MDM2 in MI and DM + MI rats. (A): Representative Western blot for MDM2, (B): Densitometric analysis of MDM2 immunoreactivity. Arrow shows MDM2 degradation product. In all samples, the densitometric measurement of MDM2 immunoreactivity was normalized to α-tubulin expression. **P = .003; ***P < .0001.Back to article page
