Table 2. Table showing β-actin dynamics changes upon dominant negative Rac1 expression.

	t1/2 (seconds)
	Fast	Slow
Control	19.5±2.3	445.7±65.2
ET-1	10.1±2.8*	176.9±15.7*
N17	61.8±10.5*	1484±197.7*
ET-1 + N17	15.3±2.9#	621.8±106.2#

FRAP experiments were performed in adult cardiomyocytes co-expressing the β-actin-GFP and N17 Rac following their treatment with +/− 100 nM ET. Analyses were made in at least 10 independent cells for statistical evaluation. Values are expressed as Mean ± S.D. *p<0.05 when compared to control. ^#p<0.05 when compared to ET-1 treated cells.
