Altogether, these results indicate the activation of Prune-1–metastatic pathway (as Prune-1 in complex formation with NME1; as previously described for medulloblastoma (Ferrucci et al., 2018)) also in these murine TNBC primary cells (i.e., MMTV–Prune-1/Wnt1 cells), thus overall suggesting increased migratory properties of these primary Prune-1-overexpressing TNBC cells. The gene discussed is WNT1; the disease is medulloblastoma.
