Abstract
The transcript of the angiogenic factor vascular endothelial growth factor A (VEGF-A) is subject to a multitude of stimulus-dependent, posttranscriptional regulatory events, consistent with its unusually long 30 untranslated region. We have recently reported translational readthrough of VEGFA mRNA whereby translating ribosomes traverse the canonical stop codon to a conserved, downstream stop codon, generating VEGF-Ax (''x'' for extended), a novel, extended isoform with an additional 22 amino acids appended at the C-terminus. This event is the first vertebrate example of protein-regulated, programmed translational readthrough that generates a protein with a known function. Remarkably, VEGF-Ax exhibits potent antiangiogenic activity, both in vitro and in vivo, thus raising profound clinical implications, particularly with respect to cancer treatment. In this review, we discuss the potential of VEGF-Ax as a therapeutic agent and drug target, as well as its possible role in the failure of, or resistance to, conventional anti-VEGF therapies in many types of cancers.
