Cardiovascular diseases are primary cause of death worldwide, particularly among populations with sedentary lifestyles and diets rich in animal products and processed foods. Currently, public health countermeasures to these disorders focus on costly and often marginally effective interventions administered only after the development of disease. These countermeasures are mainly palliative and fail to address the underlying causes of cardiac pathologies. Previously, the authors of this report have demonstrated that sour cherry seed kernel extract (SCSE), a nontoxic low-cost plant material, strongly preserves tissues through induction of heme oxygenase-1 (HO-1), a critical host antioxidant defense enzyme. This investigation seeks to characterize underlying mechanisms of SCSE-mediated tissue protection. Isolated hearts from Sprague- Dawley rats fed 30 mg$kg21$d21 SCSE for 8 weeks, and untreated controls were mounted in a "working heart" apparatus and subjected to ischemia and reperfusion. A panel of cardiac functional evaluations was conducted on each heart. Infarct size assessments were made along with Western blot and immunohistochemical analysis for selected proteins involved in cardiovascular homeostasis. SCSE treatment was observed to improve postischemic cardiac functions and suppress infarct size. Analysis of the outcomes produced by this study is consistent with SCSE cardioprotection that involve interaction of Bcl-2 and HO-1.
