Ommittee of “La Fe” Universitary Hospital of Valencia, Spain) and conducted in accordance with the guidelines of the Declaration of Helsinki [13].Homogenization of Samples and Protein DeterminationTwenty-five milligrams of frozen left ventricle was homogenized in the FastPrep-24 homogenizer (MP Biomedicals, USA) in specifically designed Lysing Matrix tubes, in a total protein extraction buffer (2 SDS, 10 mM EDTA, 6 mM Tris Cl, pH 7.4) with protease inhibitors (25 mg/mL aprotinin and 10 mg/ mL leupeptin). The isolation of nuclear and cytoplasmic protein fraction was obtained by NE-PER method (Sermorelin web Thermo Scientific, USA). The homogenates were centrifuged and the supernatant was aliquoted. The protein content of the aliquot was determined by the Lowry method (Peterson’s Modification [15]) using bovine serum albumin (BSA) 23115181 as standard.Source of TissueExperimental material was taken from a total of 88 explanted human failure hearts, 52 from patients with ICM and 36 from patients with DCM, undergoing cardiac transplantation. Clinical history, ECG, echocardiography, hemodynamic studies, and coronary angiography data were available on all patients. The clinical characteristics of the patients are shown in Table 1. All patients were functionally classified according to the New York Heart Association (NYHA) criteria and were receiving medical treatment following the guidelines of the European Society of Cardiology [14]. Nine non-diseased donor hearts were used as control (CNT) samples. The hearts were initially considered for cardiac transplantation but were subsequently deemed unsuitable for transplantation either because of blood type or size incompatibility. The cause of death was cerebrovascular accident or motor vehicle accident. All donors had normal left ventricular 3PO site function and no history of myocardial disease or active infection at the time of transplantation. Transmural samples were taken from near the apex of the left ventricle. The ICM, DCM, and CNT samples were flushed with 0.9 NaCl and stored at 4uC for a mean time of 4.463 h from loss of coronary circulation. All tissues were obtained with informed consent of patients.Polyacrylamide Gel Electrophoresis and Western Blot AnalysisSamples were separated by Bis-Tris Midi gel electrophoresis with 4?2 polyacrylamide in a separate gel for NDC1, Nup155, Nup160, Nup153 and Nup93; and by Native Bis-Tris Mini gel electrophoresis with 4?6 polyacrylamide for TPR. After electrophoresis, the proteins were transferred from the gel to a PVDF membrane by the iBlot Dry Blotting System Ltd (Invitrogen, UK) for Western blot. The membrane 1662274 was blocked all night at 4uC with 1 BSA in Tris-buffer solution containing 0.05 Tween 20 and then for 2 h with a primary antibody in the same buffer. For TPR the Western blot was performed in a BenchPro 4100 Card Processing Station (Invitrogen, Carlsbad, CA). The primary detection antibodies used were: anti-NDC1 rabbit polyclonal antibody (1/500 dilution), anti-Nup155 rabbit polyclonal antibody (1/800 dilution), anti-Nup160 rabbit polyclonal antibody (1/800 dilution), anti-Nup153 mouse monoclonal antibody (1/30 dilution), anti-Nup93 mouse monoclonal antibody (1/500 dilution) and anti-TPR mouse monoclonal antibody (1/ 1000 dilution), from Abcam (Cambridge, UK). Monoclonal antibeta-actin antibody (1/1000 dilution) (Sigma-Aldrich, Missouri, USA) was used as loading CNT for each of the blots. Then, the bands were visualized using an acid phosphatase conjugated secondary.Ommittee of “La Fe” Universitary Hospital of Valencia, Spain) and conducted in accordance with the guidelines of the Declaration of Helsinki [13].Homogenization of Samples and Protein DeterminationTwenty-five milligrams of frozen left ventricle was homogenized in the FastPrep-24 homogenizer (MP Biomedicals, USA) in specifically designed Lysing Matrix tubes, in a total protein extraction buffer (2 SDS, 10 mM EDTA, 6 mM Tris Cl, pH 7.4) with protease inhibitors (25 mg/mL aprotinin and 10 mg/ mL leupeptin).
