    Epidermal Growth Factor-like 7 As a Novel Therapeutic Target in Mantle Cell Lymphoma (GWCC - Hall B5, Level 1) -  Nov 5, 2021 - Abstract #ASH2021ASH_4976;    
    Currently, MCL patients are treated with aggressive chemo-immunotherapy regimens followed mostly by consolidation with autologous stem cell transplantation and maintenance rituximab...To examine the therapeutic potential of targeting EGFL7 in MCL cells, we treated patient-derived xenograft (PDX) cells (n=3) with an anti-EGFL7 blocking antibody (Parsatuzumab) in vitro...Further, Anti-EGFL7 treatment decreased phospho-AKT protein levels in PDX cells and MCL cell lines compared to IgG control, suggesting blocking EGFL7 abrogates EGFR mediated downstream signals. In conclusion, this is the first report describing a role for EGFL7 in MCL growth and/or survival by modulating the EGFR-AKT signaling pathway and targeting EGFL7 using an anti-EGFL7 blocking antibody as a novel treatment to improve the outcome for MCL patients.
