(A) To induce EMT, A549 cells were treated with TGFβ or nickel for 2 days, and DLD1 cells stably expressing inducible Snai1 (Sna-ER) were exposed to 4-hydroxytamoxifen (4HT) for 2 days. Cells were subsequently subjected to RT-qPCR analysis for FBXO11 and E-cadherin.
(B) Expression of FBXO11 correlates with indicated epithelial markers and inversely with mesenchymal markers in a lung cancer cohort (n = 286). Clustering was based on expression levels of EMT markers. Green indicates lower expression, and red indicates higher expression.
(C) FBXO11 is a robust predictor for favorable clinical outcome in cancer. Kaplan-Meier 10-yr overall survival was based on expression levels of E-cadherin or FBXO11 in a large cohort of lung cancer patients (n = 1405). The online survival analysis software was previously reported [36].
