Conversely, angiotensin II (Ang II) triggers cell death and promotes myocyte hypertrophy. Moreover, activation of p53 upregulates the cellular renin-angiotensin system (RAS). Therefore, IGF-1 overexpression in FVB.Igf+/-mice may downregulate the local RAS through the attenuation of p53 and p53-inducible genes. On this basis, p53 DNA binding activity to angiotensinogen (Aogen), bax, and the AT1 receptor was determined in left ventricular myocytes from FVB.Igf-/- and FVB.Igf+/-mice. The quantity of Bax, Bcl-2, Aogen, and AT1 receptor in these cells was evaluated. The presence of Mdm2-p53 complexes was also established. Finally, Ang II levels in myocytes were measured. Upregulation of IGF-1 in myocytes was associated with a protein-to-protein interaction between Mdm2 and p53, which attenuated p53 transcriptional activity for bax, Aogen, and AT1 receptor. Similarly, the amount of Bax, Aogen, and AT1 receptor proteins in these cells decreased. In contrast, the expression of Bcl-2 remained constant. The downregulation of Aogen in myocytes from FVB.Igf+/-mice was characterized by a reduction in Ang II. In conclusion, IGF-1 negatively influences the myocyte RAS through the upregulation of Mdm2 and its binding to p53. This may represent the molecular mechanism responsible for the effects of IGF-1 on cell viability and myocyte hypertrophy in the nonpathological and pathological heart in vivo."xsd:string |
