EEF1D and ovarian cancer: Compared with cells without KD or KO of EEF1D expression, the viabilities of ovarian cancer cells with EEF1D KD or KO were significantly decreased following DDP treatment (P < 0.05 or P < 0.01); the effect in SKOV3/DDP cells was more significant than that in SKOV3 cells (Fig. 2 A and B).
