Anatol J Cardiol 18: 3‑9, 2017]. This error arose inadvertently; the corrected version of Fig. 3, also containing the correct data for Fig. 3B, is shown opposite. The authors are grateful to the Editor of International Journal of Molecular Medicine for allowing them the opportunity to publish this Corrigendum, and stress that this error did not significantly influence either the results or the conclusions of the paper.
