The transcription factor HoxB5 stimulates vascular remodelling in a cytokine-dependent manner.

Aims: Proper blood vessel formation is essential in health and is often dysregulated in ischaemic diseases. Therefore, regulatory mechanisms that control angiogenesis and arteriogenesis are required to improve treatment of ischaemic diseases. The aim of this study was to investigate the role of homeobox transcription factor HoxB5 overexpression during revascularization in ischaemic disease.

Inflammatory neovascularization during graft-versus-host disease is regulated by αv integrin and miR-100.

Acute graft-versus-host disease (GvHD) is a complex process involving endothelial damage and neovascularization. Better understanding of the pathophysiology of neovascularization during GvHD could help to target this process while leaving T-cell function intact. Under ischemic conditions, neovascularization is regulated by different micro RNAs (miRs), which potentially play a role in inflamed hypoxic GvHD target organs.

MicroRNA-100 regulates neovascularization by suppression of mammalian target of rapamycin in endothelial and vascular smooth muscle cells.

Background: The adaptive growth of blood vessels is an important protective mechanism in cardiovascular disease. However, the underlying regulatory mechanisms of this process are only partly understood. Recently, small endogenous RNAs (microRNAs [miRNAs]) were found to play an important role in embryonic and postnatal vascular development.
