Western blot analysis revealed that TEFT treatment increased expression of the epithelial marker E‐cadherin while decreasing expression of mesenchymal markers N‐cadherin, Vimentin, and YKL‐40 in both U87 and U251 cells, indicating that TEFT treatment suppressed the EMT process in GBM cells (Figure 3B,C). The gene discussed is VIM; the disease is glioblastoma.
