The overarching goal of Task 6.3.4 is the development of molecules and strategies to target alternative splicing events involved in heterogenous diseases, syndromes, and multi-systemic conditions currently lacking curative options. In light of the fact that a vigorous neo-vasculature development is characteristic of aggressive primary tumors and metastases and that Tumor Endothelial Cells (TECs) are readily accessible to therapeutic agents, targeted delivery of bio-active agents to the tumoral neo-vasculature is a particularly promising anticancer therapeutic modality. In the past the group of Dr. Ghigna identified Alternative Splicing (AS) variants of cell surface molecules restricted to TECs and with relevant roles for tumor angiogenesis. Our main interest is to use antisense oligonucleotides (ASO) targeting TEC-restricted AS variants to block neo-angiogenesis and consequently tumor progression.
