In addition to miR-196b, ETS2 has been reported to regulate the expression of miR-126 in endothelial cells and may mediate the angiogenesis process (34).
Given that increased PI3K and PKB/Akt signaling have also been shown to mediate angiogenesis through increased expression of vascular endothelial growth factor [ 44], loss of PTEN may promote tumor growth in vivo by an angiogenic mechanism.
Tissue transglutaminase is thought to mediate angiogenesis by crosslinking the extracellular matrix (Haroon et al, 1999).
In addition, AMPK has been proposed to mediate angiogenesis stimulated by adiponectin and hypoxia [15,18].
Experimental evidence indicates that GRO- β, also known as the chemokine CXCL2, may mediate varied functions, such as attracting neutrophils to sites of inflammation, regulating angiogenesis, and modulating neurotransmitter release [ 24– 26].
Growth-related oncogene- (GRO-) β is a member of the CXC chemokine family, which may mediate various functions, such as attracting neutrophils to sites of inflammation, regulating angiogenesis, and participating in tumorigenesis and progression.
Acute alternation of VEGF and Ang-1 in the ischemic core may mediate BBB leakage, whereas up-regulation of VEGF/VEGF receptors and Ang/Tie-2 at the boundary zone may regulate angiogenesis with neovascularization in ischemic brain.
Both moieties may mediate atherogenicity.
Finally, ADAMs may promote cancer growth and metastasis by mediating angiogenesis or pathological neovascularisation.
While VEGF mediated angiogenesis contributes to the repair and remodeling of degenerated tendons, invasion of endothelial cells may also weaken the mechanical stability of the tendon [ 8].
