NRP1 and neoplasm: Beyond Sema4F, multiple axon-related molecules, classified for their function in tumor axonogenesis, such as Bmp7, Robo1, Fibronectin, or Nrp1, and the synaptic adhesion molecule IGSF11/VSIG-3 are regulated upon TGFβ−mediated EMT induction, hnRNP E1 silencing, or Platr18 overexpression (Fig 2F and Tables S2 and S3).
