Previous studies have shown that mulberry water extracts (MWEs), which contain polyphenolic compounds, have an antiatherosclerotic effect in vivo and in vitro through stimulating apoptosis of vascular smooth muscle cells (VSMCs). Histological analysis was performed on atherosclerotic lesions from high-cholesterol diet (HCD)-fed rabbits after treatment with 0.5-1% MWEs for 10 weeks. Immunohistochemistry showed that the expressions of SMA, Ras, and matrix metalloproteinase-2 in the VSMCs were dose-dependently inhibited after MWE treatment. The antimigratory effects of MWEs on A7r5 VSMCs were assessed by western blot analysis of migration-related proteins, visualization of F-actin cytoskeleton, and reverse transcription polymerase chain reaction. The results showed that MWEs inhibited VSMC migration through reducing interactions of the integrin-beta(3)/focal adhesion kinase complex, alterations of the cytoskeleton, and downregulation of glycogen synthase kinase 3 beta/nuclear factor ?B signaling. Taken together, MWEs inhibited HCD-induced rabbit atherogenesis through blocking VSMC migration via reducing interactions of integrin-beta(3) and focal adhesion kinase and downregulating migration-related proteins.
