Figure 6From: RETRACTED ARTICLE: Slug down-regulation by RNA interference inhibits invasion growth in human esophageal squamous cell carcinomaImmunohistochemical and TUNEL staining in vivo xenograft model. A,Immunohistochemistry with monoclonal antibodies directed against human Slug was performed to compare the Slug expression profile of Slug- and vector-transfectedclones in the in vivo human xenograft model. Bars, 21 mm. (a) Slug is intensely expressed in siRNA mock-transfected group.(b)Slug is weakly expressed in siRNA Slug-transfected group, B, TUNEL staining in the mock siRNA(c) and the siRNA Slug transfected groups(d).Back to article page
