Figure Lengend Snippet: Role of NFIX in gastric cancer (GC) cells: proliferation, stemness, and kinase activity regulation. (A) Western blot analysis of NFIX in five non-neoplastic or GC cell lines. (B) Western blot analysis of NFIX in MKN-45 cells transfected with the negative control or NFIX siRNA. (C) Effect of NFIX knockdown on cell growth in MKN-45 cells transfected with the negative control or NFIX siRNA. (D and E) Wound-healing assay in MKN-45 cells transfected with the negative control or NFIX siRNA. (D) The mean percentage of wound closure. (E) Representative image. (F) Number and size of spheroids formed by MKN-45 cell lines transfected with negative control or NFIX siRNA. (G) The heatmap shows the gene expression profile of 3 independent sets of MKN-45 cells transfected with the negative control or NFIX siRNA by RNA sequencing analysis. Data are color-coded to reflect the gene expression level. (H) Volcano plot comparing MKN-45 cells transfected with the negative control and that with NFIX siRNA. (I) Gene Ontology enrichment analysis of the top 50 genes.
Article Snippet: The sections were incubated with rabbit polyclonal anti- NFIX antibody (NBP2-15039, 1:200; Novus Biologicals, LLC, USA) for 1 h at room temperature, followed by incubation with EnVision+ peroxidase-conjugated anti-rabbit secondary antibody for 1 h. For the color reaction, the sections were incubated with the Dako Liquid DAB+ Substrate Chromogen System (#K3468, Santa Clara, CA, USA) for 3 min.
