Key result
Statins downregulate the activity of small G proteins (Rac1 and RhoA) in cardiomyocytes in culture and in vivo, reducing myocardial expression of ANF and MLC-2.
Why the study?
Do statins reduce myocardial expression of hypertrophy markers ANF and MLC-2 in cardiomyocytes and spontaneously hypertensive rats?
Do statins reduce myocardial expression of hypertrophy markers ANF and MLC-2 in cardiomyocytes and spontaneously hypertensive rats?
Statins downregulate the activity of small G proteins (Rac1 and RhoA) in cardiomyocytes, reducing myocardial expression of hypertrophy markers ANF and MLC-2, suggesting a potential mechanism to prevent cardiac hypertrophy.

Suggests statins may blunt angiotensin II-driven hypertrophy via Rac1/RhoA in cardiomyocytes; hypothesis-generating in mice, human relevance unknown.
Ulrich Laufs (2002) studied Cardiac hypertrophy. Statins (atorvastatin) was evaluated on Rac1 and RhoA activity, ANF and MLC-2 expression. Statins downregulate the activity of small G proteins (Rac1 and RhoA) in cardiomyocytes in culture and in vivo, reducing myocardial expression of ANF and MLC-2.
