ChIP-seq analysis for endogenous FOXO1 in human endothelial cells

FOXO1 was involved in various biologucal processes. In endothelial cells, it has reported that FOXO1 was phosphorylated by PI3K-Akt signaling, and it was nuclear exclusion by short-term VEGF stimulation. This event turns off the expression of apoptosis-related genes, it protects the cell from apoptosis. On the other hand, long-term VEGF stimulation, FOXO1 re-entry into the nucleus and induces the expression of different genes. Therefore, to identify genes regulated by FOXO1-binding in long-term VEGF stimulation, we performed ChIP-seq analysis of human unbilical vein endothelial cells (HUVECs) stimulated by VEGF for 18h. HUVEC cells were treated with human recombinant VEGF-A165 for 18h. The chrometin sample was used for ChIP-seq analysis with FOXO1 antibody and inputs.
