MicroRNA-365 promotes the contractile phenotype of venous smooth muscle cells and inhibits neointimal formation in rat vein grafts.

The high rate of autologous vein graft failure caused by neointimal hyperplasia remains an unresolved issue in the field of cardiovascular surgery; therefore, it is important to explore new methods for protecting against neointimal hyperplasia. MicroRNA-365 has been reported to inhibit the proliferation of vascular smooth muscle cells (SMCs). This study aimed to test whether adenovirus-mediated miR-365 was able to attenuate neointimal formation in rat vein grafts.

Dedicator of cytokinesis 2 silencing therapy inhibits neointima formation and improves blood flow in rat vein grafts.

Objective: The high rate of vein graft failure due to neointimal hyperplasia is a major challenge for cardiovascular surgery. Finding novel approaches to prevent neointimal hyperplasia is important. Thus, the purpose of this study was to investigate whether dedicator of cytokinesis 2 (DOCK2) plays a role in the development of neointima formation in the vein grafts.

MicroRNA-146a sponge therapy suppresses neointimal formation in rat vein grafts.

The long-term failure of vein grafts due to neointimal hyperplasia remains a difficult problem in cardiovascular surgery. Exploring novel approaches to prevent neointimal hyperplasia is important. MicroRNA-146a (miR-146a) plays an essential role in promoting vascular smooth muscle cell (VSMC) proliferation.
