摘要： This study aims to determine the effects of SCNT on cardiac development of SCNT pigs through proteomic methods. Heart proteins from three adult SCNTs and two normal reproductive Bama miniature pigs were extracted, separated, and identified via comparative proteomic methods, including two-dimensional gel electrophoresis, mass spectrometry, and Western blot. Eleven differentially expressed spots were identified as differentially expressed proteins, of which five spots were upregulated proteins such as cardiac myosin heavy chain, cathepsin D, and heat shock protein beta-1 (HSP27). By contrast, six spots were downregulated proteins such as alpha skeletal muscle and actin. The results also demonstrated that nuclear transfer might result in abnormal expression of some important proteins in hearts from SCNT pigs, and affect the cardiac development in SCNT pigs survival.
