Background

Angiopoietin-like, also known as angiopoietin-related proteins, are structurally related to the angiopoietins. Seven ANGPTL proteins have been identified (ANGPTL1 through 7). ANGPTL4 plays an important role in numerous cancers and is implicated in the metastatic process by modulating vascular permeability, cancer cell motility and invasiveness. ANGPTL4 contributes to tumor growth and protects cells from anoikis, a form of programmed cell death induced when contact-dependent cells detach from the surrounding tissue matrix. ANGPTL4 secreted from tumors can bind to integrins, activating downstream signaling and leading to the production of superoxide to promote tumorigenesis. ANGPTL4 disrupts endothelial cell junctions by directly interacting with integrin, VE-cadherin and claudin-5 in a sequential manner to facilitate metastasis. ANGPTL4 functions as a matricellular protein to facilitate skin wound healing.

ANGPTL4 induces nitric oxide production through an integrin/JAK/STAT3-mediated upregulation of iNOS expression in wound epithelia, and enhances angiogenesis to accelerate wound healing in diabetic mice. Cyclic stretching of human tendon fibroblasts stimulated the expression and release of ANGPTL4 protein via TGF-β and HIF-1α signalling, and the released ANGPTL4 was pro-angiogenic. ANGPTL4 is also a potent angiogenic factor whose expression is up-regulated in hypoxic retinal Müller cells in vitro and the ischemic retina in vivo.
