Besides, expression of EZH2, p‐PI3K, p‐AKT and Ki‐67 was decreased, and expression of PTEN and miR‐30b‐5p was elevated in tumour tissues of nude mice injected with oe‐EZH2 + exo‐miR‐30b‐5p, but further addition of SC79 elevated expression of p‐PI3K, p‐AKT and Ki‐67, and exerted no alteration in expression of miR‐30b‐5p, EZH2 and PTEN (Figures 5C–E and S3A). This evidence concerns the gene EZH2 and neoplasm.
