"Interestingly, in breast cancer, HH–GLI signaling was triggered in an autocrine manner by stimulation of the VEGF receptor neuropilin-2 (NRP2), xref whose expression in NSCLCs has been linked to unfavorable outcomes. xref , xref , xref In its role as a VEGF receptor, NRP2 specifically binds both VEGFA and VEGFC, xref and VEGF/NRP signaling impacts the biology of stem-like tumor cells in various types of cancer. xref , xref , xref We wondered whether oncogenic NRP2/ERK signaling might be the upstream cause of the noncanonical GLI1 activity in LAC cells."
