Proteomic analysis of vascular tissue from critical limb ischemia mouse models treated with Etrinabdione

Vasculogenic therapies have been investigated for the treatment of peripheral artery disease (PAD) with very limited success in clinical trials. The isoform PP2A (protein phosphatase 2)/B55alpha inhibits the activity of the prolyl hydroxylase 2 (PHD2) and activates the hypoxia inducing factor-1alpha (HIF-1alpha), playing a key role in in vessel remodeling. Thus, PP2A/B55alpha activators may have the potential to induce angiogenesis and arteriogenesis. Herein we investigated the pharmacological attributes of VCE-004.8 (Etrinabdione) and its effectiveness in a murine model of critical limb ischemia.
