CDH1 and glioblastoma: Figure 3 shows the levels of E-cadherin, vimentin and fibronectin in HCC827, H1975, H1993 and A549 lung cancer cell lines, MCF7 and MDA-MB-231 breast cancer cell lines and H1080 fibrosarcoma and U87-MG glioblastoma cells. Exposure to NETs caused a decrease of E-cadherin in HCC827, H1975 and MCF-7 cells and an increase of vimentin in HCC827 and H1975 cells indicating the activation of the EMT program in those cells. The results of quantitative analysis of E-cadherin and vimentin levels in HCC827 and H1975 cells are shown in Supplementary Figure S2.
