Figure 3: Silence of miR-29a and its effects on the infrasound-modulated proliferation and collagen synthesis of cultured cardiac fibroblasts stimulated by angiotensin II. (a) miR-29a in the cardiac fibroblasts was knocked down by siRNA interference with scrambled siRNA as control. (b) [3H] thymidine incorporation. (c) [3H] proline incorporation was determined in the siRNA or control cells treated with Ang II with or without exposure to infrasound. The results were presented as times of control. The data were from three independent experiments. **P < 0.01 versus control group; ##P < 0.01 versus Ang II group
