Figure 4.

The protein and mRNA expression levels of RhoA in primary cultured cardiomyocytes. The mRNA and protein expression levels of RhoA both showed no significant difference when treated with the 3 different statins. OB – the cardiomyocytes without treatment; S1 – the cardiomyocytes treated with insulin; S2 – the cardiomyocytes treated with insulin and 1-μM statins; S3 – statins the cardiomyocytes treated with insulin and 5-μM statins; S4 – the cardiomyocytes treated with insulin and 1-μM statins.
