Figure Lengend Snippet: NDRG4 depletion in breast tumor cells increases lymph node adhesion and cell migration toward VN. a NDRG4 expression meta-analysis in human breast cancer cell lines using GOBO application . Breast cancer subtypes can be identified by different colors: red = Basal A, gray = Basal B and blue = Luminal cells. b Analysis of NDRG4 mRNA expression levels in MCF-7 cells transfected with NDRG4-shRNAs or scramble control (shSCR). Expression levels are relative to wild type cells and normalized to hydroxymethylbilane synthase (HMBS) gene. Error bars represent SEM of biological replicates ( n = 5). *** p < 0.001, ns = not significant, by one-way ANOVA. c Western blot analysis of NDRG4 expression in cytoplasmic extracts of MCF-7 shNDRG4s or shSCRs cells, using antibodies against NDRG4 and Actin. MCF-7 cells express all the three isoforms of NDRG4: 37 kDa (NDRG4-B), 39 kDa (NDRG4-B var ) and 41 kDa isoform (NDRG4-H). For simplicity, results obtained for two independent shNDRG4 clones were grouped and presented as the shNDRG4 group. ( d , left) Representative images of adherent red fluorescent MCF-7 cells on frozen rat lymph node sections. d , e Quantification of adherent MCF7 ( d ) and T47D ( e ) breast tumor cells in lymph nodes sections (right, n = 4 independent experiments for MCF-7 and 3 for T47D, ** p < 0.01 by two-tailed t test). f Stationary adhesion assays showed that NDRG4 knockdown promotes ‘adhesive switch’ between FN and VN. Error bars represent SEM of biological replicates ( n = 4). Cells do not adhere to albumin control (BSA, data not shown). * p < 0.01, ** p < 0.01, ns = not significant by two-tailed t tests. g , h Haptotactic cell migration toward VN was analyzed by transwell migration assay in MCF-7 ( g ) and T47D ( h ) cell lines. Error bars represent SEM of biological replicates ( n = 4). *** p < 0.001 by two-tailed t tests
