In addition, IHC staining and qRT-PCR assays on tumor sections and fresh tissues of nude mice showed that the number of Ki67-positive cells and the expression level of lncRNA HAGLROS in lncRNA HAGLROS overexpressing tissues were significantly higher than those in the control group, while the number of Ki67-positive cells in lncRNA HAGLROS low-expressing tissues and the expression levels of lncRNA HAGLROS were significantly lower than those of the control group (Fig. 2G, H). Here, MKI67 is linked to neoplasm.
