Article Title: ZIC1 acts a tumor suppressor in breast cancer by targeting survivin
doi: 10.3892/ijo.2018.4450
Figure Lengend Snippet: Assessment of lentiviral transfection in breast cancer cells. (A) MDA-MB-231 (upper diagram) and SK-BR3 (low diagram) transfected with rLV-ZsGreen-PGK-Puro in a bright field microscope (left panels: magnification, ×100) and green fluorescence microscope (right panels: magnification, ×100). (B) Ectopic expression of ZIC1 and survivin in MDA-MB-231 and SK-BR3 cells was examined by western blot analysis. (C) Relative protein expression of ZIC1 in the 'ZIC1' groups was obviously higher than that in the 'Vector' groups, while the expression of survivin in the 'ZIC1' groups (Z) was obviously lower than that in the 'Vector' groups (V), *** P<0.001; (D) The 2 −ΔΔCq value of ZIC1 in the 'ZIC1' groups was markedly higher than that in the 'Vector' groups, while the 2 −ΔΔCq value of survivin in the 'ZIC1' groups was markedly lower than that in the 'Vector' groups, *** P<0.001.
