Transcriptional profiling of VEGF-A and VEGF-C target genes in lymphatic endothelium reveals endothelial-specific molecule-1 as a novel mediator of lymphangiogenesis.

ABSTRACT: Lymphatic vessel growth and activation, mediated by vascular endothelial growth factor (VEGF)-C and/or VEGF-A, have important roles in metastasis and in chronic inflammation. We aimed to comprehensively identify downstream molecular targets induced by VEGF-A or VEGF-C in lymphatic endothelium by analyzing the time-series transcriptional profile of treated human dermal lymphatic endothelial cells (LECs). We identified a number of genes, many not previously known to be involved in lymphangiogenesis, that were characterized either as early response genes, transiently induced genes, or progressively induced genes. Endothelial-specific molecule-1 (ESM-1) was one of the genes that were most potently induced by both VEGF-A and VEGF-C. Whereas ESM-1 induction by VEGF-A was mainly dependent on acti
