Key result
MicroRNA-33 attenuates vein graft neointimal hyperplasia by preventing stretch-induced SMC proliferation.
Why the study?
Does miR-33 protect against neointimal hyperplasia induced by arterial mechanical stretch in grafted veins?
Does miR-33 protect against neointimal hyperplasia induced by arterial mechanical stretch in grafted veins?
miR-33 attenuates neointimal hyperplasia in grafted vessels via the BMP3-smad signaling pathway, suggesting a potential therapeutic target to prevent vein graft failure.
May support miR-33 targeting to limit vein graft hyperplasia; leaves open translation from animal models to clinical use.
The miR-33-BMP3-smad signalling pathway protects against venous SMC proliferation in response to the arterial stretch. miR-33 is a target that attenuates neointimal hyperplasia in grafted vessels and may have potential clinical applications.
