Stromal Expression of miR-143/145 Promotes Neoangiogenesis in Lung Cancer Development

This study shows that miR-143/145 expressed from the tumor microenvironment stimulates neoangiogenesis and supports tumor expansion in the lung, demonstrating a surprising role for the putative tumor suppressor miRNA cluster in promoting tumorigenesis. We propose inhibition of miR-143/145 as a therapeutic avenue to modulate tumor neoangiogenesis.
