doi: 10.1038/ncb3295
Figure Lengend Snippet: ( a–c ) Immunohistochemical staining using antibodies against phospho-BRK (Tyr351) (a), phospho-HIF1α (Tyr565) (b), or phospho-GPNMB (Tyr525) (c) in human breast cancer tissues. Upper panel: representative image. Scale bars, 100µm; Lower panel: statistics analysis based on non-TNBC tissues ( n =5) vs . TNBC tissues ( n =40) and non-Metastasis (TnN0M0) TNBC ( n =27) vs . Metastasis (TnN>0M>0) breast tissues ( n =13) (median, two-way ANOVA). ( d–f ) Upper panel: statistical analysis of immunohistochemical staining using antibodies against phospho-BRK (Tyr351) (d), phospho-HIF1α (Tyr565) (e) or phospho-GPNMB (Tyr525) (f) in human breast cancer tissues including TNBC ( n =10), ER−/PR−/HER2+ ( n =7), ER+/PR+/HER2- ( n =18), and ER+/PR+/HER2+ ( n =2) (median, two-way ANOVA). Lower panel: Pearson’s correlation analysis comparing staining density between LINK-A expression and phospho-BRK (Tyr351) (d), phospho-HIF1α (Tyr565) (e), or phospho-GPNMB (Tyr525) (f) within the TNBC group ( n =10 tissue samples, Fisher’s exact test). ( g–i ) Kaplan-Meier survival analysis of phosphor-BRK (Tyr351) (g), phosphor-HIF1α (Tyr565) (h), and phospho-GPNMB (Tyr525) (i) status in breast cancer patients ( n =160, Gehan-Breslow test).
