Mechanical overload activates hypoxia-inducible factor 1-alpha (HIF1a) in tenocytes to drive tendinopathy independently of VEGFA-mediated vascular ingrowth, and tenocyte Hif1a deletion prevents overload-induced tendon degeneration in mice.

This study shows that PIK3CAH1047R mutation causes clonal expansion in capillary and venous endothelial cells but not in arterial cells, revealing stage-dependent responses and a protective mechanism against arterial damage.

This study shows that Caspase-8 promotes angiogenesis in endothelial cells through a cell death-independent mechanism involving p38 MAPK activation and VE-cadherin destabilization.
