- LINC00607 is a long non-coding RNA that regulates alternative splicing of the VEGF receptor FLT1 in endothelial cells, influencing angiogenesis.
- Knockout of LINC00607 increases production of soluble FLT1 (sFLT1), a decoy receptor that inhibits VEGF signaling and impairs angiogenesis, which can be reversed with sFLT1-neutralizing antibodies.
- LINC00607 interacts with U2 snRNA and depends on the chromatin remodeler BRG1 to prevent exon 15 inclusion in FLT1, thus reducing sFLT1 formation.
- A splice-blocking morpholino targeting the FLT1 intron14/exon15 junction reduces sFLT1 production and enhances VEGF-A-mediated sprouting by interacting with LINC00607 and U2 snRNA.
- LINC00607 expression is downregulated in preeclampsia and inversely correlates with sFLT1 levels in vascular diseases, suggesting a role in the pathophysiology of conditions like preeclampsia.
