Human umbilical vein endothelial cells express the dux4 protein: a basis for further vascular research

The high rate of DUX4 protein expression observed in HUVECs is the first positive data and suggests a potential role for DUX4 protein in endothelial cells. Further analyses including the functional analyses of DUX4, PAX3 and PAX7 in ECs could improve our understanding of a vascular pathogenesis in DUX4-related diseases, particularly in the contexts of cancer and facioscapulohumeral dystrophy.
