NRP-1/TNC/Integrin β3/FAK/Akt/NF-kB schematic signaling pathway. Schema to illustrate the identified mechanism by which NRP-1 activates TNC-dependent integrin β3 signaling via phosphorylation of FAK/Akt-473/NF-κB p65. In addition, NRP-1 upregulates TNFR2 expression and downregulates BCRP/ABCG2, TNFR1, and PI3K/Akt-308. Solid black lines indicate identified direct interactions in the pathway whereas dashed lines indicate indirect effects of NRP-1 overexpression via unidentified mechanisms. The key denotes the arrows and colors used in the illustration
