As expected, SFRS9 protein expression was obviously upregulated in mice injected with SFRS9-overexpressed Caco-2 cells (Figures 8G, H), while it was significantly downregulated in the tumor tissues of mice with shSFRS9-transfected HCT116 cells injection (Figures 8G, J). This evidence concerns the gene SRSF9 and neoplasm.
