Abstract

Retinoblastoma, a well-vascularized tumor that is dependent on a very robust angiogenic response, is the most common intraocular malignancy in children. Tissue factor (TF) is known to regulate tumor progression and in the present study we demonstrated that TF regulates tumor angiogenesis of retinoblastoma. In an orthotopic transplantation model of retinoblastoma, TF was selectively expressed in the proliferative area of retinoblastoma including tumor vessels as well as tumor cells, where TF expression was co-localized with endothelial cells of tumor vessels. TF expression progressively increased with fibroblast growth factor-2 (FGF-2)-induced proliferation of human umbilical vein endothelial cells (HUVECs), which was effectively inhibited by blockade of the TF pathway by TF pathway inhibitor (TFPI). In addition, FGF-2-induced angiogenic processes of migration and tube formation of vascular endothelial cells were also effectively suppressed by TFPI, which would be mediated by inhibition of extracellular signal-regulated kinase activation. Therefore, further to our previous report that TF is involved in tumor cell proliferation of retinoblastoma, our current data suggest that blockade of the TF pathway by TFPI could effectively inhibit tumor growth by suppressing tumor cell proliferation and tumor angiogenesis at the same time.
