Immunohistochemistry was adopted to detect Ki-67 expression in transplanted tumor tissues and it was reported that versus the sh-FOXP4-AS1-1 + sh-CTR group, Ki-67 expression was elevated in the sh-FOXP4-AS1-1 + sh-ZC3H12D group (P < 0.05) (Fig. 7G–H). This evidence concerns the gene FOXP4 and neoplasm.
