| Outline of Final Research Achievements |
To develop an acoustic gene control system, researches consist of the following 4 topics were carried out; 1) establishment of direct/indirect acoustic system for cultured cells, 2) whole genome-wide identification of sound-sensitive genes, 3) isolation of sound-sensitive genetic regions, and 4) investigation of acoustic effects on cell differentiation. By using custom-made acoustic systems, more than 400 sound-sensitive genes were identified by the RNA-seq analysis. Although several promoter regions of these genes exhibited sound-sensitive activity control, the level of the control was not as high as expected from the gene analyses. Continuous exposure of myoblast cells under differentiation medium with acoustic stimulation significantly induced myotube formation. These findings revealed the future utility of acoustic stimulation in next-generation gene/cell control techniques.
