Sprague Dawley rats : A model of successful heart aging / D. Capitanio, R. Leone, C. Fania, E. Torretta, C. Gelfi. - In: EUPA OPEN PROTEOMICS. - ISSN 2212-9685. - 12:(2016 Sep 01), pp. 22-30. [10.1016/j.euprot.2016.03.017]
Abstract:
Aging is a universal phenomenon involving the whole body and is characterized by metabolic and physiological decline, leading to cardiovascular defects and heart failure. To characterize the molecular basis of physiological cardiac aging, the proteomic profiles of Sprague Dawley rat hearts of 6, 22 and 30 months were analysed by DIGE and immunoblotting. Results indicate changes in myosin binding protein C, aldehyde dehydrogenase, serpins and sirtuin-3 which protects from the opening of the mitochondrial permeability transition pore induced by cyclophilin D increment. Conversely, an increase of fusion, a decrease of mitochondrial fission and the activation of the non-canonical autophagy pathway were observed. These results support the hypothesis of successful aging in this rat model.
