Key findings
1. QKI-7 is significant upregulated in diabetic human iPS cell-derived ECs, and in blood vessels from diabetic critical limb ischemia patients.
2.The expression of QKI-7 is tightly controlled by RNA splicing factors-CUG-BP and hnRNPM through direct binding in diabetic ECs.
3.QKI-7 upregulation is correlated with disrupted cell barrier, compromised angiogenesis and enhanced monocyte adhesion.
4.When QKI-7 was knocked-down in vivo in ECs in the hindlimb ischemia model in diabetic mice, reperfusion and blood flow recovery were promoted.
5.Manipulation of QKI-7 represents a promising strategy for the treatment of diabetic vascular complications.
