干扰抑制

Mechanical strains also regulated the protein and mRNA expression of several differentiation markers, as well as the activation of extracellular signal-regulated kinases, p38 MAP kinase and protein kinase B in a frequency-dependent manner. Furthermore, the inhibition of p38 pathway could block the strain-frequency induced the phenotype modulation of VSMCs, neither ERKs nor Akt. Frequency of mechanical strain, not conditioned medium, regulated the phenotype of VSMCs in a frequency-dependent manner. Rho-GDI alpha was suppressed by the mechanical strain at 1Hz.
