Suppressing NFAT Increases VEGF Signaling in Hemangiomas

Infantile hemangiomas represent the most common tumor of endothelial cell (EC) origin, yet the mechanisms regulating hemangioma EC behavior are poorly understood. A new study by Jinnin et al. demonstrates that enhanced VEGFR2 signaling in hemangioma ECs is caused by suppression of NFAT (nuclear factor of activated T cells)-dependent VEGFR1 expression.
