MAGEE1 overexpression inhibits cell viability in vitro. (a) The expression of MAGEE1 in the ES-2 and OVISE cell lines transfected with empty vector control (NC), MAGEE1-WT, MAGEE1-Mut1 or Magee1-Mut2 was determined by RT-PCR. (b) Western blotting of MAGEE1 expression levels in ES-2 and OVISE cells transfected with empty vector control (NC), MAGEE1-WT, MAGEE1-Mut1 or Magee1-Mut2. (c) CCK8 assay showed a significant reduction in the viability of cells transfected with MAGEE1-WT, MAGEE1-Mut1 or Magee1-Mut2 compared to cells transdfected with empty vector control (NC).
