      Vasiliauskaite, Kotryna; Fleten, Karianne Giller; Barkovskaya, Anna; Nygaard, Vigdis; Haugen, Mads Haugland; Engesæter, Birgit Øvstebø; Mælandsmo, Gunhild; Prasmickaite, Lina (Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
      The knowledge on how tumor-associated stroma influences efficacy of anti-cancer therapy just started to emerge. Here we show that lung fibroblasts reduce melanoma sensitivity to the BRAF inhibitor (BRAFi) vemurafenib only if the two cell types are in close proximity. In the presence of fibroblasts, the adjacent melanoma cells acquire de-differentiated mesenchymal-like phenotype. Upon treatment with ...
