PKNOX2 suppressed gastric tumor growth in vivo. a Ectopic expression of PKNOX2 suppressed the growth of MKN45 xeongrafts in vivo. b Representative image of MKN45 xenografts in nude mice (upper). PKNOX2 overexpression reduced both tumor volume (P < 0.001) and weight (P < 0.05) (lower). c Overexpression of PKNOX2 in MKN45 xenografts was confirmed by RT-PCR. d PKNOX2 inhibited cell proliferation in vivo, as evidenced by Ki-67 staining(P < 0.01). e Ectopic expression of PKNOX2 suppressed the growth of AGS xeongrafts in NOD-SCID mice. f Representative image of AGS xenografts (upper). PKNOX2 overexpression reduced both tumor volume and weight (lower)(both P < 0.001). g Overexpression of PKNOX2 in AGS xenografts was confirmed by RT-PCR. (*P < 0.05; **P < 0.01; ***P < 0.0001)
