Description:
Epidermal growth factor-like domain 7 (EGFL7) is a secreted protein. We previously found that EGFL7 is up-regulated in primary AML blasts and that a high mRNA expression correlates with shorter event-free and overall survival in AML patients (Papaioannou et al. PNAS 2017;114(23)). However, the underlying mechanism by which EGFL7 promotes leukemogenesis is largely unknown. To identify EGFL7 binding partners, we took an unbiased high-throughput approach by using an antibody interaction-array to measure the ability of EGFL7 to bind directly ~400 proteins expressed by primary AML blasts. Using this strategy, we found in cell lysates of 3 AML patients that EGFL7 binds several signaling proteins important for normal and malignant hematopoiesis including NOTCH (in all patients P
