Abstract:
Coarctation of the aorta (CoA) is an anatomically defined lesion with a surgical solution and no established mechanistic etiology. TFAP2β has demonstrated specificity to ductal smooth muscle cells in CoA. In mammalian models, ductal TFAP2β protein expression declines across the third trimester, with protein undetectable at or near term in mice and rats as well as corroborating mRNA decline in non-human primates. We report robust postnatal TFAP2β protein colocalized to the elastin-poor obstructive shelf in a surgical CoA resection.
