We also verified that MEF2C affects the adhesion of tumor cells to the extracellular matrix by cell adhesion assays (Figures 9D, E).The results showed that the adhesion of si-MEF2C cells to the extracellular matrix such as vitronectin (Figure 9D) and fibronectin (Figure 9E) was reduced compared with the control group. The gene discussed is VTN; the disease is neoplasm.
