In the tumor tissues following oe-LINC00858 + sh-PCNP treatment, RAD21 expression was not altered while PCNP expression and phosphorylation levels of STAT3 and STAT5 were decreased in those following oe-LINC00858 + sh-NC treatment (Fig. 6B, and Supplementary Fig. 1H). This evidence concerns the gene PCNP and neoplasm.
