Transgenic expression of different ultrasound intensities and LM concentrations.

Ultrasound intensity (W/cm2)	LM concentration (%)
	3	6	10
0.8	9.03±2.33	18.33±2.59a	16.59±5.13
1.0	12.73±2.81	31.18±5.48b,d	19.16±6.26
1.2	13.48±1.13	24.47±3.24b	13.32±1.03b,c

The data were presented as the mean values ± SEM, n=3. With the fixed ultrasound intensity condition,

^aP<0.05,

^bP<0.01, as compared with the LM concentration of 3%;

^cP<0.01, as compared with the LM concentration of 6%. With the fixed LM concentration,

^dP<0.05, as compared with the ultrasound intensity of 0.8 W/cm².

LM, liposome microbubble.
