E Western blot analysis of the expression of the invasive and proliferative phenotype markers EPHA2, EGFR, AXL, PDGFRβ, SOX10, and MITF in TINCR-overexpressing MM13 and MM2 cells. Total protein lysates were extracted from PDX cells 7 days after infection and analyzed by immunoblot assay using the indicated antibodies. Vinculin was used as loading control. This experiment is representative of three independent experiments showing comparable levels of TINCR overexpression (8-10 folds).
