EEF2K and neoplasm: The results showed that eEF2K knockdown significantly decreased the tumor size and weight, and this inhibitory effect was stronger in immunocompetent mice than in immunodeficient mice (figure 6A–D, online supplemental figures S4 and S5A), implying that the smaller size of tumors with eEF2K knockdown was probably due to the enhanced activity of immune cells in the tumor microenvironment.
