EEF2K and cancer: Gorur et al. (2021) transfected MDA-MB-231 and MDA-MB-436 cell lines with miR-22-3p. Later, grafts of the same type of cell lines were put into the mammary fat of mice, which were then injected with single-lipid liposomal NPs (SLNPs) loaded with miR-22-3p. In both cases, expression levels of miR-22-3p were restored, silencing eEF2K, inducing apoptosis, and inhibiting cancer cell proliferation, colony formation, invasion, and metastasis (Gorur et al., 2021) (Figure 3E).
