About Enhancer
| Enhancer ID: | E_02_0311 |
| Species: | mouse |
| Position : | chr7:30330197-30332197   |
| Biosample name: | |
| Experiment class : | High+Lowthroughput |
| Enhancer type: | Enhancer |
| Disease: | Nothing |
| Pubmed ID: | 29753018 |
| Enhancer experiment: | Etv2 knockdown,In situ hybridization(ISH),Luciferase experiments,Chromatin immunoprecipitation and sequencing (ChIP-Seq),immunohistochemistry,Dual?Luciferase Reporter Assay,PCR, |
| Enhancer experiment description: | In Etv2-inhibited embryos and larvae, the number of lymphatic progenitors is greatly reduced, the major lymphatic vessel, the thoracic duct, is absent or severely fragmented, and lymphangiogenesis-associated marker expression, including lyve1b, prox1a, and vegfr3/flt4, is strongly downregulated. We also demonstrate that lymphatic progenitors in Etv2 deficient embryos fail to respond to Vegfc signaling. Chromatin immunoprecipitation and sequencing (ChIP-Seq) studies using differentiated mouse embryonic stem (ES) cells as well as luciferase reporter studies in the ES cells and in zebrafish embryos argue that Etv2 directly binds the promoter/enhancer regions of Vegfc receptor Vegfr3/Flt4 and lymphatic marker Lyve1, and promotes their expression. Together these data support a model where Etv2 initiates lymphangiogenesis by directly promoting the expression of flt4 within the posterior cardinal vein. |
