The present invention associates multiple long non-coding RNA (lncRNA) with key functions of endothelial cells. The lncRNA of the present invention are therefore useful as novel drug targets for the manufacturing of medicines for the treatment of cardiovascular diseases or pathological angiogenesis in context of proliferative diseases such as cancer. Modulation of the function or expression of the lncRNA of invention can induce or repress angiogenesis and vessel growth or repair in endothelial cells. Provided are further methods for the modulation of endothelial cell functions in vitro, for example, in the context of tissue engineering.
