Remarkably, tissues of all tumors derived from CEBPG-NC A2780 cells had significantly higher levels of CEBPG and SLC7A11 expression than those derived from CEBPG-Sh1 A2780 cells (Fig. 7E–G), and SLC7A11 expression level correlated positively with CEBPG expression level in orthotopic ovarian tumor tissues (R2 = 0.8149, P < 0.0001; Fig. 7H). This evidence concerns the gene CEBPG and ovarian neoplasm.
