DANCR knockdown blocked the tumor formation in vivo involving KLF8 activation. CAL-27 or TCa-8113 cells transfected with shRNA against DANCR were inoculated subcutaneously into the nude mice. Xenografts were measured every 4 days with a caliper. a Tumor volumes were measured every 4 days. b Mice were sacrificed after 25 days, and xenograft tumors were excised and weighed. c Relative expression of MMP-2 and MMP-9 protein in tumor tissues was measured by western blot after 25 days. d Relative expression of KLF8 protein in tumor tissues was examined by western blot after 25 days. e Immunofluorescence staining was performed to investigate KLF8 immunoreactive materials in tumor tissues after 25 days. ***p < 0.001, versus to sh-NC
