Figure 4. Immunoblots of COX17, COX11, SCO2 and COX-IV proteins from the PE treated primary cultures of neonatal rat cardiomyocytes.

Control (cultured for 72 h with non-PE or other treatment), PE (PE treated for 72 h), Cu (cultured without treatment for 48 h then treated with Cu for 24 h), and PE+Cu (PE treated for 48 h followed by Cu treatment for 24 h). The bar graphs show the quantitative analysis of the intensity of immunoblots by densitometry. Values are means ± SEM. * significantly different from control group (P<0.05).
