Fig. 8. Proposed mechanism for the enhancement of sprouting angiogenesis by BACE1-dependent APP processing.

Fig. 8

Schematic diagram of our working hypothesis for increased sprouting angiogenesis in TgCRND8 (b) compared to WT (a) tissue. Increased APP processing by BACE1 in TgCRND8 OBSCs competes with NOTCH3 for γ -secretase or reduces γ-secretase activity, thereby lowering transcriptional signalling through NICD. This reduces Notch3-Jag1 expression via autoregulatory mechanisms, thereby releasing the inhibitory influence on sprouting angiogenesis. Created with BioRender.
